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
