    Sendmail fails - problem creating SMTP socket

    Thanks to piti and tarn on the Linux (server) forum, I have an answer to this: (note that I mangled the IPs below for security reasons!) There was an entry in sendmail.cf: O DaemonPortOptions=Port=smtp,Addr=634.615.608.641, Name=MTA which was different from the current eth1: address...

    Strange Port 25 failure - RedHat 2.4.20 kernel

    Thanks to piti and tarn! (note that I mangled the IPs below for security reasons!) There was an entry in sendmail.cf: O DaemonPortOptions=Port=smtp,Addr=634.615.608.641, Name=MTA which was different from the current eth1: address 734.745.712.726 . When I changed sendmail.cf to match the...

    Fool Ultrabac into thinking Samba file server is NT Workstation

    If you invoke: $ smbclient -L //nt4machinename (from a Linux machine with smb client loaded) you get back: Domain=[MYDOMAIN] OS=[Windows NT 4.0] Server=[NT LAN Manager 4.0] If you invoke: $ smbclient -L //nt4machinename (from a Linux machine with smb client loaded) you get back...

    Strange Port 25 failure - RedHat 2.4.20 kernel

    I don't think so. eth0: ip has not changed, and (of course) lo: ip has not changed. eth1: is acquired by DHCP, and is of course subject to change, but 1) changes in assigned ip have not affected me previously, and 2) assigned ip did not change on this reboot. Please note that it seems nothing...

    Strange Port 25 failure - RedHat 2.4.20 kernel

    Sorry - I was not very clear on this ... One of the first things I did was to turn off all firewalling (stop iptables, check to be sure all firewalling rules were flushed.) The port 25 problem is the same whether iptables are applied or completely cleared (flushed). -Scott Wagner

    Strange Port 25 failure - RedHat 2.4.20 kernel

    I am (or was) running sendmail 8.11.6 on a 2.4.20 kernel (Red Hat Linux 7.3). The installation has been running without problems for many months. A few days ago, upon reboot, sendmail began failing with the following entries in maillog: Aug 21 12:12:40 mymachine sendmail[2421]: starting daemon...
