RE: [cobalt-users] VERY Slow access to Cobalt RaQ4

["Devin Smith" <devinsmith@xxxxxxxxxxxxxxx>]

I think this whole gethostbyaddr thing has thrown everyone off the trail
and made them think it is strictly a DNS issue.  We have another raq
located in the same premises using the same DNS servers, with no
problem.  The server worked fine until the cmuImport script hung.

When a site is added to a RaQ, what files are modified to reflect the
addition of the IP/address?  I'm sure I'm missing one somewhere that has
a corrupt entry.  Thanks!

Reverse lookup [ gethostbyaddr() ] doesn't care how many 'A' records or
how 
many MX records you have, it wants a PTR record.
If you are not having the delay then somebody, somewhere is answering
the 
gethostbyaddr() call.

Many services on a RaQ, as a security measure will attempt to 
gethostbyaddr(), the timeout can be something like 25 seconds, and two
or 
three attempts will be made.

The ironic thing, is that the cobalt sever will go ahead and service the

request, even though the gethostbyaddr() call failed, although you can 
configure such that it will not.

If you know the users IP address host name then entering the IP address
- 
host name in /etc/hosts file will resolve the gethostbyaddr() call FAST.
