Re: 20050929: Problem with new ldm server

Robert,
I'm afraid I don't see a problem. All of the "SVC_UNAVAIL"
error-messages occur after the top-level LDM server indicates it
received a SIGTERM signal -- after which I wouldn't expect an
ldmping(1) to succeed.
The only program in the LDM package that generates a SIGTERM is the
ldmadmin(1) script when "stop" or "restart" is requested. Of course,
the LDM user can always manually send a SIGTERM to the LDM server.
What, exactly, is the problem?
Regards,
Steve Emmerson

Guys,
I have included the dvb-s logs, a tcpdump , a netstat output, and the
ldmd.conf file to document a problem. This problem shows up in the dvb-s
file: "mistral ldmping[5866]: SVC_UNAVAIL 0.000756 0 localhost
RPC: Program not registered"
From the command line I am able to ldmping active ldm servers.
If you want to connect and have a look, the new computer is currently
named: mistral.srcc.lsu.edu 130.39.188.225. The ldm password is the
same as the samoon ldm password.
I am drawing a blank at this point.
Bob
