Files in /etc/sysconfig ======================= /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 indicates that the clock is set to UTC; anything else indicates that it is set to local time ARC=true on alpha only indicates the ARC console's 42-year time offset 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/init: BOOTUP= BOOTUP=color means new (as of RH6.0) boot display. BOOTUP=verbose means old style display Anything else means new display, but without 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. MAGIC_SYSRQ=yes|no Set to 'no' to disable the magic sysrq key, and Stop-A (break on serial console.) on SPARC. PROMPT=yes|no Set to 'no' to disable the key check for interactive mode. /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) In addition, /dev/mouse points to the mouse device. /etc/sysconfig/network: NETWORKING=yes|no HOSTNAME= Note: for compatibility with some old software people might install (like trn), the /etc/HOSTNAME file should contain the same value as here. FORWARD_IPV4=yes|no (The current Red Hat Linux installation sets this to no by default for RFC compliance, but if FORWARD_IPV4 is not set at all, forwarding is *enabled* for compatibility with the configuration files used on Red Hat Linux versions 4.2 and earlier.) DEFRAG_IPV4=yes|no Set this if you want to automatically defragment IPv4 packets. This is a good idea for masquerading, and a bad idea otherwise. It defaults to 'no'. GATEWAY= GATEWAYDEV= (e.g. eth0) NISDOMAIN= 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. /etc/sysconfig/static-routes: Contains lines of the form: net netmask gw may be a device name to have the route brought up and down with the device, or "any" to have the correct devices calculated at run time. /etc/sysconfig/routed: SILENT=yes|no EXPORT_GATEWAY=yes|no /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=$LOGROOT/counter-file For rewinding when done...might not use. BACKUPTAB=/etc/backuptab The file in which we keep our list of backup(s) we want to make. /etc/sysconfig/sendmail: DAEMON=yes|no yes implies -bd QUEUE=1h given to sendmail as -q$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.) 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. /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/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 "clone" (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 clone 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 USERCTL=yes|no BOOTPROTO=none|bootp|dhcp PEERDNS=yes|no modify /etc/resolv.conf if peer uses msdns extension (PPP only) or DNS{1,2} are set, default to "yes". DNS{1,2}= provide DNS addresses that are dropped into the resolv.conf file if PEERDNS is not set to "no". 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= 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) 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.) /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
