Dear developers:
I'm using Samba-3.5.8 on Linux (Gentoo, amd64) as a file server, and using
some Windows based OSes as clinet. And something strange happened to me.
Things went as follows:
1. If there was no dot (".") in the hostname of server, then no matter
whether the DNS server (in /etc/resolv.conf) was set correctly or not,
everything went fine. Client can access shares (provided server) normally.
2. If there was dot in hostname of server, and if the DNS Server was set
correctly (or just left as blank), server worked normally.
3. If there was dot in hostname of server, and the DNS Server was set
incorrectly, all client could not connect to the server, with a message
indicated that the address of server could not be accessed.
My friend and I payed some time on it. We found that in the last situation, the
Samba server may spend a long time to look up the computer name (name of server
or client). But before the look up ends, the client would treat this as a
timeout.
I don't know whether we are right about this. And if we were, why everything
goes fine in the 2nd case?
Any information will be appreciated.
Best regards.

A dot in hostname is not RFC compliant, so change the servers hostname.

Thanks for your reply. But both the wikipeida (http://en.wikipedia.org/wiki/Hostname) and documents provided by CentOS (http://www.centos.org/docs/5/html/5.2/Deployment_Guide/s2-sysconfig-network.html) point out that they should be Fully Qualified Domain Name (FQDN), such ashostname.expample.com. And also, that does not make sense for the 2nd case in the previous mail. What's more, I'm interested in how Samba treat the server's hostname. But I failed to search it through the code. Help, please. Thanks. Tubo.

Another interest thing: if we use a Linux client to access the shares from server, it connects successfully in all cases. Don't know why. Thanks again.
