I've apparently got something wrong with the hostnaming process that is causing sendmail to balk.
Jan 30 12:41:02 localhost sendmail[10391]: My unqualified host name (localhost) unknown; sleeping for retry Jan 30 12:41:20 localhost sendmail[10445]: My unqualified host name (localhost) unknown; sleeping for retry Other evidence of a problem is that the hostname cmd returns: hostname chub (as expected) but hostname --long localhost (should return chub.local.net0 I think) I've setup the normal files for this like this: # cat /etc/conf.d/hostname # Set to the hostname of this machine HOSTNAME="chub" # cat /etc/conf.d/domainname # When setting up resolv.conf, what should take precedence? # If you wish to always override DHCP/whatever, set this to 1. OVERRIDE=1 # To have a proper FQDN, you need to setup /etc/hosts and /etc/resolv.conf # properly (domain entry in /etc/resolv.conf, and FQDN in /etc/hosts). # DNSDOMAIN="local.net0" # This only set what /bin/hostname returns. If you need to setup NIS, meaning # what /bin/domainname returns, please see: # # http://www.linux-nis.org/nis-howto/HOWTO/ # # NISDOMAIN= # cat /etc/hosts 127.0.0.1 localhost chub ## ============================ 192.168.0.4 chub.local.net0 chub # gentoo #=========================================================== 192.168.0.3 mobile2.local.net0 mobile2 # winxp (home) [...] domain local.net0 search local.net0 nameserver 192.168.0.20 -- gentoo-user@gentoo.org mailing list
