Files in /etc/sysconfig ======================= /etc/sysconfig/authconfig used by authconfig to store information about the system's user information and authentication setup; changes made to this file have no effect until the next time authconfig is run USEHESIOD=no Whether or not the hesiod naming service is in use. If not set, authconfig examines the passwd setting in /etc/nsswitch.conf. USELDAP=no Whether or not LDAP is used as a naming service. If not set, authconfig examines the passwd setting in /etc/nsswitch.conf. USENIS=no Whether or not NIS is in use. If not set, authconfig examines the passwd setting in /etc/nsswitch.conf. USEKERBEROS=no Whether or not Kerberos is in use. If not set, authconfig examines the settings in /etc/pam.d/system-auth. USELDAPAUTH=no Whether or not LDAP is being used for authentication. If not set, authconfig examines the settings in /etc/pam.d/system-auth. Note that this option is separate from USELDAP, and that neither implies the other. USEMD5=no Whether or not MD5-based hashing should be used when setting passwords. If not set, authconfig examines the settings in /etc/pam.d/system-auth. This option affects authentication using both local files and LDAP. USESHADOW=no Whether or not shadow passwords are in use. If not set, authconfig checks for the existence of /etc/shadow. USESMBAUTH=no Whether or not SMB authentication is in use. If not set, authconfig examines the settings in /etc/pam.d/system-auth. /etc/sysconfig/autofsck does not normally exist; if it does, it can influence a choice whether or not to fsck after a crash AUTOFSCK_TIMEOUT=5 Number of seconds to wait for console user to make a choice AUTOFSCK_DEF_CHECK=no If the user does not respond, choose whether or not to fsck /etc/sysconfig/clock: deprecated values from earlier releases: CLOCKMODE=GMT indicates that the clock is set to UTC CLOCKMODE=ARC on alpha only indicates the ARC console's 42-year time offset is in effect currently correct values: UTC=true,yes Indicates that the hardware clock is set to UTC. UTC=no,false Indicates that the hardware clock is set to Local Time. Not having UTC set defaults to the last used (if recorded in the adjtime file), or to localtime, if not adjtime file exists. ARC=true on alpha only indicates the ARC console's 42-year time offset is in effect; otherwise the normal Unix epoch is assumed. SRM=true on alpha only indicates the SRM 1900 epoch is in effect; otherwise the normal Unix epoch is assumed. ZONE="filename" indicates the zonefile under /usr/share/zoneinfo that /etc/localtime is a copy of, for example: ZONE="US/Eastern" /etc/sysconfig/desktop: DESKTOP=GNOME|KDE|AnotherLevel This determines the default desktop for new users. DISPLAYMANAGER=GNOME|KDE|XDM This determines display manager started by /etc/X11/prefdm, independent of the desktop. /etc/sysconfig/init: BOOTUP= BOOTUP=graphical means use X Windows graphical boot up BOOTUP=color means colorized text mode boot display. BOOTUP=verbose means old style display Anything else means simplified display, but without color or ANSI-formatting LOGLEVEL= Sets the initial console logging level for the kernel. The default is 7. 8 means everything (including debugging); 1 means nothing except kernel panics. syslogd will override this once it starts. RES_COL= Column of the screen to start status labels at. Defaults to 60 MOVE_TO_COL= A command to move the cursor to $RES_COL. Defaults to nasty ANSI sequences output by echo -e. SETCOLOR_SUCCESS= A command to set the color to a color indicating success. Defaults to nasty ANSI sequences output by echo -e setting the color to green. SETCOLOR_FAILURE= A command to set the color to a color indicating failure. Defaults to nasty ANSI sequences output by echo -e setting the color to red. SETCOLOR_WARNING= A command to set the color to a color indicating warning. Defaults to nasty ANSI sequences output by echo -e setting the color to yellow. SETCOLOR_NORMAL= A command to set the color to 'normal'. Defaults to nasty ANSI sequences output by echo -e. PROMPT=yes|no Set to 'yes' to enable the key check for interactive mode as well as asking if a filesystem check should be done. Default is 'no' and the kernel command line option "forcefsck" can be used to check the filesystems and "confirm" can be used to enable interactive startup questions. obsoleted values from earlier releases: MAGIC_SYSRQ=yes|no Setting this to 'no' used to disable the magic sysrq key and Stop-A (break on serial console) on SPARC. This setting has been moved into kernel.sysrq and kernel.stop-a settings respectively in /etc/sysctl.conf. Setting either of them there to 0 disables it, setting it to 1 enables it. STOP_A=yes|no Setting this to 'no' used to disable the Stop-A (break on serial console) key on SPARC. This setting has been moved into kernel.stop-a setting in /etc/sysctl.conf. Setting it there to 0 disables it, setting it to 1 enables it. The setting should be present on SPARC only. /etc/sysconfig/keyboard: KEYTABLE= for example: KEYTABLE="/usr/lib/kbd/keytables/us.map" If you dump a keymap (using 'dumpkeys') to /etc/sysconfig/console/default.kmap it will be loaded on bootup before filesystems are mounted/checked. This could be useful if you need to emergency type the root password. This has to be a dumped keymap, as opposed to copying the shipped keymap files, as the shipped files include other maps from the /usr/lib/kbd/keytables directory. KEYBOARDTYPE=sun|pc on SPARC only, sun means a sun keyboard is attached on /dev/kbd, pc means a PS/2 keyboard is on ps/2 port. /etc/sysconfig/mouse: MOUSETYPE=microsoft|mouseman|mousesystems|ps/2|msbm|logibm|atibm| logitech|mmseries|mmhittab XEMU3=yes|no (emulate three buttons with two buttons whenever necessary, most notably in X) DEVICE= (the device of the mouse) In addition, /dev/mouse points to the mouse device. /etc/sysconfig/network: NETWORKING=yes|no HOSTNAME= GATEWAY= GATEWAYDEV= (e.g. eth0) NISDOMAIN= VLAN=yes|no IPX=yes|no IPXAUTOPRIMARY=on|off (note, that MUST be on|off, not yes|no) IPXAUTOFRAME=on|off (again, not yes|no) IPXINTERNALNETNUM= IPXINTERNALNODENUM= All the IPX stuff is optional, and should default to off. NETWORKING_IPV6=yes|no Enable or disable global IPv6 initialization Default: no IPV6FORWARDING=yes|no Enable or disable global forwarding of incoming IPv6 packes on all interfaces. Note: Actual packet forwarding cannot be controlled per-device, use netfilter6 for such issues Default: no IPV6INIT=yes|no Enable or disable IPv6 configuration for all interfaces Use with caution! Default: value not set in this file IPV6_AUTOCONF=yes|no Sets the default for device-based autoconfiguration. Default: yes if IPV6FORWARDING=no, no if IPV6FORWARDING=yes IPV6_ROUTER=yes|no Sets the default for device-based Host/Router behaviour. Default: yes if IPV6FORWARDING=yes, no if IPV6FORWARDING=no IPV6_AUTOTUNNEL=yes|no Controls automatic IPv6 tunneling. Default: no IPV6_DEFAULTGW= (optional) Add a default route through specified gateway An interface can be specified: required for link-local addresses Examples: IPV6_DEFAULTGW="3ffe:ffff:1234:5678::1" Add default route through 3ffe:ffff:1234:5678::1 IPV6_DEFAULTGW="3ffe:ffff:1234:5678::1%eth0" Add default route through 3ffe:ffff:1234:5678::1 and device eth0 IPV6_DEFAULTGW="fe80::1%eth0" Add default route through fe80::1 and device eth0 Note: if IPV6_DEFAULTGW is specified with %interface scope and it doesn't match IPV6_DEFAULTDEV, IPV6_DEFAULTDEV is ignored. Note: it's preferred to use %interface for all addresses, not just link-local if you have multiple IPv6-enabled interfaces. IPV6_DEFAULTDEV= (optional) Add a default route through specified interface without specifying next hop Type of interface will be tested whether this is allowed Examples: IPV6_DEFAULTDEV="eth0" INVALID example! IPV6_DEFAULTDEV="ppp0" IPV6_DEFAULTDEV="sit1" Examples for 6to4 IPV6_DEFAULTDEV="tun6to4" Add default route through dedicated 6to4 tunnel device "tun6to4", if configured Note: "tun6to4" does not support an additional IPV6_DEFAULTGW. Other interfaces prefer IPV6_DEFAULTGW, if specified. IPV6_RADVD_PIDFILE= (optional) Location of PID file for controlling radvd, see IPV6_CONTROL_RADVD Default: "/var/run/radvd/radvd.pid" Example: IPV6_RADVD_PIDFILE="/some/other/location/radvd.pid" IPV6TO4_RADVD_PIDFILE= (obsolete) As above, still supported for a while for backward compatibility. IPV6_RADVD_TRIGGER_ACTION=startstop|reload|restart|SIGHUP (optional) How to trigger radvd in case of 6to4 or PPP action startstop: radvd starts if interface goes up and stops if interface goes down using initscript call of radvd with related parameter reload|restart: initscript of radvd is called with this parameter SIGHUP: signal HUP is sent to radvd, pidfile must be specified, if not the default Default: SIGHUP IPv6 options above can be overridden in interface-specific configuration. obsoleted values from earlier releases: FORWARD_IPV4=yes|no This setting has been moved into net.ipv4.ip_forward setting in /etc/sysctl.conf. Setting it to 1 there enables IP forwarding, setting it to 0 disables it (which is the default for RFC compliance). DEFRAG_IPV4=yes|no Setting this to yes used to automatically defragment IPv4 packets. This is a good idea for masquerading, and a bad idea otherwise. This setting was moved into net.ipv4.ip_always_defrag setting in /etc/sysctl.conf. It is no longer valid for 2.4 kernels. /etc/sysconfig/static-routes-ipv6: Contains lines of the form: IPv6-network IPv6-gateway IPv6-network must be a device name to have the route brought up and down with the device For example: eth0 fec0:0:0:2::/64 fec0:0:0:1:0:0:0:20 adds a route for IPv6 network fec0:0:0:2::/64 through fec0:0:0:1:0:0:0:20 eth0 2000::/3 3ffe:ffff:0:1::1 so-called "default" routes for clients sit1 2000::/3 adds routes through dedicated tunnel interface sit1 tun6to4 3ffe:ffff:1234::/56 adds routes through hardwired 6to4 tunnel interface tun6to4 tun6to4 3ffe:ffff:5678::/56 ::5.6.7.8 adds routes through hardwired 6to4 tunnel interface tun6to4, specifying next hop Notes: * default routes (such as the "2000::/3" shown above) should be set with IPV6_DEFAULTGW and IPV6_DEFAULTDEV, see more above. * tunnel device "sit0" is not supported here, routes will never be applied /etc/sysconfig/routed: SILENT=yes|no EXPORT_GATEWAY=yes|no /etc/sysconfig/rawdevices: This is used for setting up raw device to block device mappings. It has the format: For example: /dev/raw/raw1 /dev/sda1 /dev/raw/raw2 8 5 /etc/sysconfig/pcmcia: PCMCIA=yes|no PCIC=i82365|tcic PCIC_OPTS= CORE_OPTS= CARDMGR_OPTS= /etc/sysconfig/amd: ADIR=/.automount (normally never changed) MOUNTPTS='/net /etc/amd.conf' (standard automount stuff) AMDOPTS= (extra options for AMD) /etc/sysconfig/tape: DEV=/dev/nst0 Tape device. Use the non-rewinding one for these scripts. For SCSI tapes this is /dev/nst#, where # is the number of the tape drive you want to use. If you only have one then use nst0. For IDE tapes you use /dev/ht#, where # is the number of the tape drive you want to use (usually ht0). For floppy tape drives use /dev/ftape. ADMIN=root Person to mail to if the backup fails for any reason SLEEP=5 Time to sleep between tape operations. Some drives need a bit more than others, but 5 seems to work for 8mm, 4mm, and DLT BLOCKSIZE=32768 This worked fine for 8mm, then 4mm, and now DLT. An optimal setting is probably however much data your drive writes at one time. SHORTDATE=$(date +%y:%m:%d:%H:%M) A short date string, used in backup log filenames. DAY=$(date +log-%y:%m:%d) This is used for the log file directory. DATE=$(date) Regular date string, used in log files. LOGROOT=/var/log/backup Root of the logging directory LIST=$LOGROOT/incremental-list This is the file name the incremental backup will use to store the incremental list. It will be $LIST-{some number}. DOTCOUNT=$LOGROOT/.count For counting as you go to know which incremental list to use COUNTER=$LOGROOT/counter-file For rewinding when done...might not use. BACKUPTAB=/etc/backuptab The file in which we keep our list of backup(s) we want to make. /etc/sysconfig/saslauthd: used by the saslauthd init script (part of the cyrus-sasl package) to control which arguments are passed to saslauthd at startup time; changes made to this file have no effect until saslauthd is restarted MECH=shadow controls which data source saslauthd will consult when checking user passwords; run 'saslauthd -a' to get a full list of available authentication mechanisms SOCKETDIR=/var/run/saslauthd controls in which directory saslauthd will be directed to create its listening socket; any change to this value will require a corresponding change in client configuration files /etc/sysconfig/sendmail: DAEMON=yes|no yes implies -bd (i.e., listen on port 25 for new mail) QUEUE=1h given to sendmail as -q$QUEUE -q option is not given to sendmail if /etc/sysconfig/sendmail exists and QUEUE is empty or undefined. /etc/sysconfig/i18n LANG= set locale for all categories, can be any two letter ISO language code LC_CTYPE= localedata configuration for classification and conversion of characters LC_COLLATE= localedata configuration for collation (sort order) of strings LC_MESSAGES= localedata configuration for translation of yes and no messages LC_NUMERIC= localedata configuration for non-monetary numeric data LC_MONETARY= localedata configuration for monetary data LC_TIME= localedata configuration for date and time LC_ALL= localedata configuration overriding all of the above LANGUAGE= can be a : separated list of ISO language codes LINGUAS= can be a ' ' separated list of ISO language codes The above variables are used in /etc/profile.d/lang.sh. SYSFONT= any font that is legal when used as /usr/bin/consolechars -f $SYSFONT ... (See console-tools package for consolechars command) UNIMAP= any SFM (screen font map, formerly called Unicode mapping table - see consolechars(8)) /usr/bin/consolechars -f $SYSFONT --sfm $UNIMAP SYSFONTACM= any ACM (application charset map - see consolechars(8)) /usr/bin/consolechars -f $SYSFONT --acm $SYSFONTACM The above is used by the /sbin/setsysfont command (which is run by rc.sysinit at boot time.) /etc/sysconfig/harddisks /etc/sysconfig/harddiskhd[a-h] (for specific devices) These options are used to tune (E)IDE hard drives and other devices - read the hdparm man page for more information USE_DMA=1 Set this to 1 to enable DMA. This might cause some data corruption on certain chipset / hard drive combinations. USE WITH CAUTION AND BACKUP. This is used with the "-d" option MULTIPLE_IO=16 Multiple sector I/O. a feature of most modern IDE hard drives, permitting the transfer of multiple sectors per I/O interrupt, rather than the usual one sector per interrupt. When this feature is enabled, it typically reduces operating system overhead for disk I/O by 30-50%. On many systems, it also provides increased data throughput of anywhere from 5% to 50%. Some drives, however (most notably the WD Caviar series), seem to run slower with multiple mode enabled. Under rare circumstances, such failures can result in massive filesystem corruption. USE WITH CAUTION AND BACKUP. This is the sector count for multiple sector I/O - the "-m" option EIDE_32BIT=3 (E)IDE 32-bit I/O support (to interface card). USE WITH CAUTION. LOOKAHEAD=1 Enable drive read-lookahead (safe) EXTRA_PARAMS= Add any extra parameters you want to pass to hdparm here. Files in /etc/sysconfig/network-scripts/ ======================================== /etc/sysconfig/network-scripts/ifup: /etc/sysconfig/network-scripts/ifdown: Symlinks to /sbin/ifup and /sbin/ifdown, respectively. These are the only two scripts "in" this directory that should be called directly; these two scripts call all the other scripts as needed. These symlinks are here for legacy purposes only -- they'll will probably be removed in future versions, so only /sbin/ifup and /sbin/ifdown should currently be used. These scripts take one argument normally: the name of the device (e.g. eth0). They are called with a second argument of "boot" during the boot sequence so that devices that are not meant to be brought up on boot (ONBOOT=no, see below) can be ignored at that time. Also, interfaces may be brought up via the hotplug scripts; in this case, ONHOTPLUG needs to be set to no to avoid this. /etc/sysconfig/network-scripts/init.ipv6-global: Not really a public file. Contains different basic settings that are set from /etc/[rc.d]/init.d/network at different stages of network initialization. /etc/sysconfig/network-scripts/network-functions: Not really a public file. Contains functions which the scripts use for bringing interfaces up and down. In particular, it contains most of the code for handling alternative interface configurations and interface change notification through netreport. /etc/sysconfig/network-scripts/network-functions-ipv6: Not really a public file. Contains functions which the scripts use for bringing IPv6 on interfaces up and down, like addresses, routes, forwarding handling and static or automatic tunneling. /etc/sysconfig/network-scripts/ifcfg- and /etc/sysconfig/network-scripts/ifcfg-:: The first defines an interface, and the second contains only the parts of the definition that are different in a "alias" (or alternative) interface. For example, the network numbers might be different, but everything else might be the same, so only the network numbers would be in the alias file, but all the device information would be in the base ifcfg file. The items that can be defined in an ifcfg file depend on the interface type. The really obvious ones I'm not going to bother to define; you can figure out what "IPADDR" is, I think... :-) Base items: NAME= Most important for PPP. Only used in front ends. DEVICE= IPADDR= NETMASK= GATEWAY= ONBOOT=yes|no ONHOTPLUG=yes|no USERCTL=yes|no BOOTPROTO=none|bootp|dhcp MTU= Default MTU for this device WINDOW= Default window for routes from this device PEERDNS=yes|no modify /etc/resolv.conf if peer uses msdns extension (PPP only) or DNS{1,2} are set, or if using pump or dhcpcd. default to "yes". DNS{1,2}= provide DNS addresses that are dropped into the resolv.conf file if PEERDNS is not set to "no". SRCADDR= use the specified source address for outgoing packets HWADDR= ethernet hardware address for this device MACADDR= Set the hardware address for this device to this. Use of this in conjunction with HWADDR= may cause unintended behavior. NOZZEROCONF= Set this to not set a route for dyamic link-local addreses over this device. PERSISTENT_DHCLIENT=yes|no|1|0 Without this option, or if it is 'no'/'0', and BOOTPROTO=dhcp, dhclient is run for the interface in "one-shot" mode; if the dhcp server does not respond for a configurable timeout, then dhclient exits and the interface is not brought up - the '-1' option is given to dhclient. If PERSISTENT_DHCLIENT=yes, then dhclient will keep on trying to contact the dhcp server when it does not respond - no '-1' option is given to dhclient. DHCPRELEASE=yes|no|1|0 With this option set to 'yes' (1), when a dhcp configured interface is brought down with 'ifdown', the lease will be released. Otherwise, leases are not released. If BOOTPROTO is not "none", then the only other item that must be set is the DEVICE item; all the rest will be determined by the boot protocol. No "dummy" entries need to be created. Base items being deprecated: NETWORK= BROADCAST= Alias specific items: ONPARENT=yes|no Whether to bring up the device when the parent device is brought up. Default: yes IPv6-only items for real interfaces: IPV6INIT=yes|no Enable or disable IPv6 configuration for this interface Default: no IPV6FORWARDING=yes|no Enable or disable global forwarding of incoming IPv6 packets Note: Obsolete in interface specification! Default: no IPV6ADDR=[/] Specify a primary static IPv6 address here Optional, if normal host and a router advertisement daemon is on local link Required, if node is a router and interface should route packets Note: if prefix length is omitted, 64 is assumed Example: IPV6ADDR="3ffe:ffff:0:5::1" IPV6ADDR="3ffe:ffff:0:1::1/128" IPV6ADDR_SECONDARIES="[/] ..." (optional) A list of secondary IPv6 addresses (e.g. useful for virtual hosting) Example: IPV6ADDR_SECONDARIES="3ffe:ffff:0:1::10 3ffe:ffff:0:2::11/128" IPV6_MTU= (optional) Optional, dedicated MTU of this link Note: Must be greater or equal to 1280. Example: IPV6_MTU="1280" Special configuration options for multi-homed hosts etc. IPV6_ROUTER=yes|no: Controls IPv6 autoconfiguration IPV6_AUTOCONF=yes|no: Controls IPv6 autoconfiguration Defaults: Global IPV6FORWARDING=yes: IPV6_AUTOCONF=no, IPV6_ROUTER=yes Global IPV6FORWARDING=no: IPV6_AUTOCONF=yes Optional settings for a 6to4 tunnel IPV6TO4INIT=yes|no Enable or disable 6to4 tunneling setup Default: no IPV6TO4_RELAY= (optional) IPv4 address of the remote 6to4 relay Note: if this is omitted, ::192.88.99.1 (the anycast relay address) is chosen IPV6TO4_IPV4ADDR=[/] (optional) Overwrite local IPv4 address which is accessable from the Internet (optional, in case of static IPv4-NAT behind a router or other special scenarios) IPV6TO4_MTU= (optional) Controls IPv6 MTU for the 6to4 tunnel Note: Must be greater or equal to 1280 Example: IPV6TO4_MTU="1280" Default: MTU of master device - 20 IPV6TO4_ROUTING="-/ ..." (optional) A list of routing tokens to setup proper IPv6 routes on the LAN Example: IPV6TO4_ROUTING="eth0-:0004::0/64 eth1-:0005::0/64" Will create one route per eth0 and eth1, taking given SLA Optional settings for a 6to4 tunnel or a ppp link IPV6_CONTROL_RADVD=yes|no (optional) Enable signalling radvd that the 6to4 prefix has been changed or a preconfigured dynamic device is up or down Default: no IPv6-only items for static tunnel interface: Interface name: sitX (X => 1) IPV6INIT=yes|no Enable or disable IPv6 configuration for this interface Default: no IPV6TUNNELIPV4= Specify IPv4 address of a foreign IPv6-in-IPv4 tunnel endpoint Example: IPV6TUNNELIPV4="1.2.3.4" IPV6TUNNELIPV4LOCAL= Specify local IPv4 address of tunnel, useful on interfaces with multiple IPv4 addresses IPV6ADDR=[/] (optional) local IPv6 address of a numbered tunnel IPV6ADDR_SECONDARIES="[/] ..." (optional) A list of secondary IPv6 addresses (example see above) IPV6_MTU= (optional) Optional, dedicated MTU of this tunnel Note: Must be greater or equal to 1280 Example: IPV6_MTU="1280" IPv6-only option to enable DHCPv6 client: DHCPV6C=yes|no This will enable the DHCPv6 client, dhcp6c, to be run for the interface. See man dhcp6c(8) and dhcp6c.conf(5). Ethernet-only items: {IPXNETNUM,IPXPRIMARY,IPXACTIVE}_{802_2,802_3,ETHERII,SNAP} configuration matrix for IPX. Only used if IPX is active. Managed from /etc/sysconfig/network-scripts/ifup-ipx ARP=yes|no (adds 'arp' flag to ifconfig, for use with the ethertap device) ETHTOOL_OPTS=... Any device-specific options supported by ethtool. For example, if you wanted to force 100Mb full duplex: ETHTOOL_OPTS="speed 100 duplex full autoneg off" Note that changing speed or duplex settings almost always requires disabling autonegotiation with 'autoneg off'. No longer supported: PROMISC=yes|no (enable or disable promiscuous mode) ALLMULTI=yes|no (enable or disable all-multicast mode) To properly set these, use the packet socket interface. Ethernet 802.1q VLAN items: DEVICE=eth0.42 Initscripts use DEV_PLUS_VID_NO_PAD naming mode for VLAN devices. Example: eth0.42 for vlan 42 on device eth0. Valid VLAN ID range is 0-4095. Most ethernet switches reserve VLAN ID 1 to be used as management VLAN; starting from VLAN ID 2 is recommended. REORDER_HDR=yes|no When enabled the VLAN device will move the ethernet header around to make it look exactly like a real ethernet device. This may help programs such as ISC dhcpd which read the raw ethernet packet and make assumptions about the location of bytes. If you don't need it turn it off because there is a small performance penalty. Default is on. PPP/SLIP items: PERSIST=yes|no MODEMPORT= LINESPEED= DEFABORT=yes|no (tells netcfg whether or not to put default abort strings in when creating/editing the chat script and/or dip script for this interface) (meaningless with WVDIALSECT) PPP-specific items WVDIALSECT= If this variable is set, then the chat script (if it exists) is ignored, and wvdial is used to open the PPP connection. DEFROUTE=yes|no (set this interface as default route? yes is default) DEBUG=yes|no (defaults to yes) turns on/off pppd and chat (if used) debugging. ESCAPECHARS=yes|no (simplified interface here doesn't let people specify which characters to escape; almost everyone can use asyncmap 00000000 anyway, and they can set PPPOPTIONS to asyncmap foobar if they want to set options perfectly) HARDFLOWCTL=yes|no (yes imples "modem crtscts" options) PPPOPTIONS= PAPNAME=<"name $PAPNAME" on pppd command line> (note that the "remotename" option is always specified as the logical ppp device name, like "ppp0" (which might perhaps be the physical device ppp1 if some other ppp device was brought up earlier...), which makes it easy to manage pap/chap files -- name/password pairs are associated with the logical ppp device name so that they can be managed together. REMIP= MTU= MRU= DISCONNECTTIMEOUT= (time to wait before re-establishing the connection after a successfully-connected session terminates before attempting to establish a new connection.) RETRYTIMEOUT= (time to wait before re-attempting to establish a connection after a previous attempt fails.) RETRYCONNECT=yes|no (defaults to yes) If this is yes, then we will re-run pppd if it exits with a "connect script failed" status. Otherwise, only one attempt is made to bring up the connection. Note that some connect scripts (for example, wvdial) might do their own retries (such as BUSY or NO DIALTONE conditions). MAXFAIL= If this is set, this will cause ppp-watch to exit after the specified number of attempts. DEMAND=yes|no Switches on demand-dialing mode using pppd's "demand" option. IDLETIMEOUT=600 The amount of time the link needs to be inactive before pppd will bring it down automatically. BOOTTIMEOUT=30 The amount of time to wait at boot before giving up on the connection. IPPP-specific items (ISDN) PROVIDER= USER= PASSWORD= ENCAP=[syncppp|] DIALMODE=[manual|auto] SECURE=off|on MSN=<> PHONE_IN= AREACODE=<> REGIONCODE=<> PHONE_OUT= BUNDLING=off|on HUPTIMEOUT= DNS1= DNS2= DOMAIN="" LAYER=[HDLC|] CALLBACK=off|on CHARGEHUP= CHARGEINT= CBHUP= CBDELAY= DIALMAX= AUTH=[+pap] [-chap] IHUP=<> DELDEFAULTROUTE=[enabled|disabled] CBCP=off|on VJ=off|on VJCCOMP=off|on AC=off|on PC=off|on BSDCOMP=off|on CCP=off|on SLAVE_DEVICE=ippp[0-9] ippp0 items being deprecated: BOOT=[on|off] will be converted to ONBOOT=[yes|no] by netconf LOCAL_IP= will be converted to IPADDR by netconf REMOTE_IP= will be converted to GATEWAY by netconf IPSEC specific items SRC=source address. Not required. DST=destination address TYPE=IPSEC SRCNET=source net (for tunneling) DSTNET=destination network (for tunneling) Manual keying: AH_PROTO{_IN,_OUT}=protocol to use for AH (defaults to HMAC-SHA1) ESP_PROTO{_IN,_OUT}=protocol to use for ESP (defaults to 3DES) KEY_AH{_IN,_OUT}=AH key KEY_ESP{_IN,_OUT}=ESP key SPI_{ESP,AH_{IN,OUT}}=SPIs to use _IN and _OUT specifiers are for using different keys or protocols for inccoming and outgoing packets. If neither _IN or _OUT variants are set for protocols or keys, the same will be used for both. Automatic keying: IKE_METHOD=PSK|X509|GSSAPI PSK=preshared keys (shared secret) X509=X.509 certificates GSSAPI=GSSAPI authentication IKE_PSK=preshared key for this connection IKE_CERTFILE=our certificate file name for X509 IKE IKE_PEER_CERTFILE=peer public cert filename for X509 IKE IKE_DNSSEC=retrieve peer public certs from DNS (otherwise uses certificate information sent over IKE) Bonding-specific items SLAVE=yes Specifies device as a slave MASTER=bondXX Specifies master device to bind to /etc/sysconfig/network-scripts/chat-: chat script for PPP or SLIP connection intended to establish the connection. For SLIP devices, a DIP script is written from the chat script; for PPP devices, the chat script is used directly. /etc/sysconfig/network-scripts/dip- A write-only script created from the chat script by netcfg. Do not modify this. In the future, this file may disappear by default and created on-the-fly from the chat script if it does not exist. /etc/sysconfig/network-scripts/ifup-post Called when any network device EXCEPT a SLIP device comes up. Calls /etc/sysconfig/network-scripts/ifup-routes to bring up static routes that depend on that device. Calls /etc/sysconfig/network-scripts/ifup-aliases to bring up aliases for that device. Sets the hostname if it is not already set and a hostname can be found for the IP for that device. Sends SIGIO to any programs that have requested notification of network events. Could be extended to fix up nameservice configuration, call arbitrary scripts, etc, as needed. /etc/sysconfig/network-scripts/ifup-routes Set up static routes for a device. /etc/sysconfig/network-scripts/ifup-aliases Bring up aliases for a device. /etc/sysconfig/network-scripts/ifdhcpc-done Called by dhcpcd once dhcp configuration is complete; sets up /etc/resolv.conf from the version dhcpcd dropped in /etc/dhcpc/resolv.conf /etc/sysconfig/network-scripts/route- Contains lines that specify additional routes that should be added when the associated interface is brought up. The files are processed by the ifup-routes script and uses the /sbin/ipcalc utility for all network masks and numbers. Routes are specified using the syntax: ADDRESSn= NETMASKn= GATEWAYn= The "n" can be any integer number, but is expected to be monotonically increasing and counting starts from 0. For example: ADDRESS0=192.168.2.0 NETMASK0=255.255.255.0 GATEWAY0=192.168.1.1 adds a network route to the 192.168.2.0 network via the gateway at 192.168.1.1. Since you must already have a route to the network of the gateway, there is no need to specify a device. Note: The ifup-routes script also supports an older syntax designed to be used directly as an argument to "/sbin/ip route add". This syntax is deprecated, but if no "ADDRESSn" lines are found the following will still work: 192.168.2.0/24 dev ppp0 adds a network route to the 192.168.2.0 network through ppp0. /etc/sysconfig/network-scripts/route6- Contains lines that are arguments to "/sbin/ip -6 route add" For example: site-local route for network fec0:0:0:2::/64 via gateway fec0:0:0:1:0:0:0:20 (e.g. on eth0): fec0:0:0:2::/64 via fec0:0:0:1:0:0:0:20 additional prefix configured to be on-link on eth0: 3ffe:fffe:1:2::/64 dev eth0 6to4 route for network 3ffe:ffff:1::/48, either: 3ffe:ffff:1::/48 3ffe:ffff:1::/48 via ::192.168.1.2 Note the special case of 6to4 interface: 'via [relay]' is automatically added if explicit 'via' wasn't specified.
