It looks to me like some problem with the hardware! :o)

For my problem, I don't think it's vserver-related. Today I could compile a vanilla 2.4.23-kernel on the relevant host-server without any vserver implementation. After a reboot in this kernel I did a "telnet remote.mail.server 25" from the host-server and it timed out as before. It looks as if it's a firewall-problem on the remote side but the admins in charge there of course claim, that it's not so.. I can't look into their firewall, but a more agressive approach with 1. "nmap -p 25 -sS remote.mail.server" and
2. "nmap -p 25 -sA remote.mail.server" from one of my host-servers showed for 1.: "port 25 open" and for 2.:"port
25 filtered". That sounds exactly like your explanation. But for my
host-servers it occurs no matter if they have a vserver-patched kernel running or not.
Too bad, for a short time I thought I might have tracked this problem down
and could accuse Herbert and the developers here of doing bad work instead of fighting alien admins.. :-)
Funny thing!
I've tried earlier to telnet on port 25 from a 2.4.18 debian machine and from a pix firewall and it worked.
All my vserver kernel were 2.4.20 onwards...
Now I've tried it from a RedHat 9 with a 2.4.24 kernel and RedHat 7.3 with a 2.4.20-RH kernel and trough a telnet proxy. Guess what - no go!
Great that this thing sorted out not to be vserver related :-) Let's go firewall admin bashing... -- lg, Chris _______________________________________________ Vserver mailing list [EMAIL PROTECTED] http://list.linux-vserver.org/mailman/listinfo/vserver
