If this helps: I have some NFS mounted drives but none of them if in
 one of the mc panes.

I would like to add that I have the same problem with version 
4.6.1-pre1a and that "options no_tld_query" in resolv.conf does not 
work (tested even after system restart)

I can (re)confirm this problem on RHEL also.

The DNS is well configured. There is no delay running "netstat -a"

I wasn't able to locate any other program with simmilar behaviour on
 these machines.

Possible hint: some partitions are mounted using NIS.

If you are searching on google after "midnight commander slow start"
 you'll see that a lot of people are encountering this issue.

I can confirm the same issue on multiple platform: OS X, Fedora and Ubuntu.

It's a real pain and this should be solved inside mc - mc is used as
a configuration tools and it's supposed to work even on systems 
where configuration is not "well done".

BTW. The solution with "options no_tld_query" in resolv.conf does 
not solves the problem in my case.

I don't remember exactly but I think it's somewhat related to 
/etc/hosts

I had this problem too
Solution is:
add "options no_tld_query" in resolv.conf

New strace file attached, now with timestamps.

It seems to timeout several times on
"RESOLVE-HOSTNAME-IPV4"

Strange because if I do nslookup with this host name it returns 
immediately..

Previous results were from MC 4.6.1 (fast starting).

Next slow results from MC 4.6.2 and a strace file.

Strace output added. Funny thing is that with strace, MC starts up 
rightaway...

you should attach the strace of such a startup.

On openSuse 11 starting mc takes a very long time: about 30s. IpV6 
is disabled but VMware player is installed and so virtual network 
devices are present.

nslookup and netstat work immidiately so it isn't the gethostbyname 
issue.

A solution would be greatly appreciated.
