Spectre hostname problem

Greetings,

My company has a problem with 1 of their Linux machines and running
spectre. I will apologize if my description of the issue seems unclear.
I'm just the contracted Linux geek, not a Cadence tools expert.



Basically, whenever a user attempts to run a simulation, spectre goes
"Netlisting" for a while and comes back with the message "Failed"
What seems to fail is the host name resolution. The host name and
the proper IP are in /etc/hosts. Incidentally, this is also the only
machine there whose host name cannot be resolved by the DNS server.

How does spectre resolve the local machine's host name before running a
sim? I've never seen a Linux application using a remove DNS to do so, but
does Spectre use a remote DNS?

Thanks.

 

Check your /etc/resolv.conf and /etc/nsswitch.conf for anything strange.

I vaguely recall this being a potential problem area - it's not just spectre,
but other Cadence applications can have the same problem.

I think they just use gethostname() internally, but I've not checked to be sure.

Andrew.

 

Thanks for the reply

well I manage to get access to the DNS server on site and added zone entries
for the machine in question, and it works fine now... so I guess the app
uses DNS instead of /etc/hosts
