BTW, initially, the packaged file is good: $ rpmpeek /ALT/Sisyphus/noarch/RPMS.classic/etcnet-0.9.10-alt18.noarch.rpm cat etc/sysconfig/network # When set to no, this may cause most daemons' initscripts skip starting. NETWORKING=yes # Used by hotplug/pcmcia/ifplugd scripts to detect current network config # subsystem. CONFMETHOD=etcnet # Used by rc.sysinit to setup system hostname at boot. HOSTNAME=localhost.localdomain DOMAINNAME=localdomain # This is used by ALTLinux ppp-common to decide if we want to install # nameserver lines into /etc/resolv.conf or not. RESOLV_MODS=yes But somehow after installer's work, the domain is lost from HOSTNAME. |
basealt-p8-wmaker-20160612-x86_64.iso emacs24-nox-24.5-alt16 I've noticed that after the installation of the system, some programs have a very long startup time. (For example, emacs24-nox starts almost eternally; I suspect that the long startup of syslogd may be also related.) The reason was that it tried to resolve the host's FQDN sending the queries many times. The reason is: $ cat etc/sysconfig/network # When set to no, this may cause most daemons' initscripts skip starting. NETWORKING=yes # Used by hotplug/pcmcia/ifplugd scripts to detect current network config # subsystem. CONFMETHOD=etcnet # Used by rc.sysinit to setup system hostname at boot. HOSTNAME=comp-sempron-processor-266d91 DOMAINNAME=localdomain # This is used by ALTLinux ppp-common to decide if we want to install # nameserver lines into /etc/resolv.conf or not. RESOLV_MODS=yes $ Actually, f we want to install # nameserver lines into /etc/resolv.conf or not. RESOLV_MODS=yes $ Actually, DOMAINNAMEinto /etc/resolv.conf or not. RESOLV_MODS=yes $ Actually, f we want to install # nameserver lines into /etc/resolv.conf or not. RESOLV_MODS=yes $ Actually, DOMAINNAME is not used. [user@test ~]$ fgrep DOMAINNAME -r /etc/rc.d /etc/net [user@test ~]$ fgrep HOSTNAME -r /etc/rc.d /etc/net /etc/rc.d/init.d/local: echo "Welcome to $HOSTNAME" >/etc/issue.net /etc/rc.d/rc.sysinit:HOSTNAME=`hostname` /etc/rc.d/rc.sysinit:if [ -x "$RESOLVE_HOSTNAME_COMMAND" ]; then /etc/rc.d/rc.sysinit: HOSTNAME="$("$RESOLVE_HOSTNAME_COMMAND")" /etc/rc.d/rc.sysinit:if [ -z "$HOSTNAME" -o "$HOSTNAME" = "(none)" ]; then /etc/rc.d/rc.sysinit: HOSTNAME=localhost /etc/rc.d/rc.sysinit:action "Setting hostname $HOSTNAME:" hostname "$HOSTNAME" /etc/rc.d/rc.sysinit: [ "$(readlink /etc/HOSTNAME)" = /proc/sys/kernel/hostname ] || /etc/rc.d/rc.sysinit: ln -snf /proc/sys/kernel/hostname /etc/HOSTNAME /etc/net/scripts/functions-ip: if [ -n "$DHCP_HOSTNAME" ]; then /etc/net/scripts/functions-ip: case "$DHCP_HOSTNAME" in /etc/net/scripts/functions-ip: print_warning "AUTO in DHCP_HOSTNAME is no longer supported." /etc/net/scripts/functions-ip: [ -n "$HOSTNAME" -a "$HOSTNAME" != "localhost" -a "$HOSTNAME" != "localhost.localdomain" ] && \ /etc/net/scripts/functions-ip: H="-h $HOSTNAME" /etc/net/scripts/functions-ip: H="-h $DHCP_HOSTNAME" /etc/net/scripts/functions-ip: if [ -n "$DHCP_HOSTNAME" ]; then /etc/net/scripts/functions-ip: case "$DHCP_HOSTNAME" in /etc/net/scripts/functions-ip: [ -n "$HOSTNAME" -a "$HOSTNAME" != "localhost" -a "$HOSTNAME" != "localhost.localdomain" ] && \ /etc/net/scripts/functions-ip: H="-F $HOSTNAME" /etc/net/scripts/functions-ip: H="-H $DHCP_HOSTNAME" /etc/net/scripts/functions: elif [ -s "$HOSTTAB" ] && grep "^$HOSTNAME " $HOSTTAB; then /etc/net/scripts/functions: NETHOST=`$DENOISE $HOSTTAB | trim | grep -m 1 "^$HOSTNAME " | cut -d' ' -f2` /etc/net/scripts/functions: NETHOST=$HOSTNAME /etc/net/options.d/50-ALTLinux-server:DHCP_HOSTNAME=localhost [user@test ~]$ Then, I ran alterator, and changed the hostname there. The correct way to configure it is as by alterator: $ cat /etc/sysconfig/network # When set to no, this may cause most daemons' initscripts skip starting. NETWORKING=yes # Used by hotplug/pcmcia/ifplugd scripts to detect current network config # subsystem. CONFMETHOD=etcnet # Used by rc.sysinit to setup system hostname at boot. HOSTNAME=test.localdomain # This is used by ALTLinux ppp-common to decide if we want to install # nameserver lines into /etc/resolv.conf or not. RESOLV_MODS=yes [user@test ~]$ (Now, emacs starts quickly.)
