SMTP Listener problem on Linux

HCL Domino Domino Forum

Hi all,

we had a Domino server 5.012 working fine on RedHat 9; yesterday we upgraded to 6.5.2 and now smtp doesn’t work. We tried also with 6.5.1 but with the same result.

The server console shows the SMTP listener task starting, but when I run a netstat -l port 25 does not show up.

When shutting down the server, the console seems to hang at the http task, after a cntrl-c it says that SMTP, and IMAP listener tasks have had trouble with the TCP stack.

Here’s the log:

18/06/2004 11.00.19 AM Unexpected TCP/IP error func: 0004h error Notes: 1C5B, NTI: 1000h, Stack: 00000009h

Do you know how to solve this?

Thanks in advance

I had similar problem with my installation. Tryexport LD_ASSUME_KERNEL=2.25

This should most probabily solve your issue.

Thanks to this forum which helped me solve my issue.

I suppose you meant 2.2.5 instead of 2.25…

For RedHat 9.0, “LD_ASSUME_KERNEL=2.4.1 server” worked for me. Heres what I went through:

Tested SMTP on port 2025, which worked.

Tried SUID on smtp

Tried running it through imapd

Combed newsgroups which failed me.

Tried kernel sysctls which would allow unprivileged daemons on ports < 1024, couldnt find one.

Thought of using iptables to dynamically map a daemon hosted on a higher port, to port 25.

Thanks for this forum, and I hope they put that little info in the Installation PDF.
