Well, if your system is the dns of your network check if the first
name server specified in your /etc/resolv.conf file is:
nameserver 127.0.0.1
I don't think the name you assign to your system is the problem.
I rather believe that the problem happens when your system cannot
reach its dns.
When I saw your question and Jim's answer, I made some test at home
because I had had this problem before and I did not know why it
happends.
1) If I don't configure my NIC, there is no problem...
... except, of course, I'm isolated.
2) If my NIC is set and I don't set a nameserver, my systems takes
3 minutes to pass, from:
Starting sshd
to:
Initial i386 initialization
when it boots, as you reported.
3) If my NIC is set and I include my computer's name in /etc/hosts
but I don't specify a name server, my system also has the
problem.
4) If my NIC is set, its name server is set, but its name is not
registered in /etc/hosts, there is no problem.
test 1-4 were repited with a non-existent name, and the results were
the same.
conclusion:
----------
The problem does not depend on the system's name.
The problem does not depend on including the system's name in /etc/hosts.
It just depends on reaching the name server.
Now, I made another test.
I created a local name server, registered my system's name
and set 127.0.0.1 as the first name server. There is no problem
even if my NIC is completely unplugged.
Set 127.0.0.1 as your first name server in /etc/hosts.
Eduardo.
