Have a look at man pages for smbclient, in particular the name resolve order (-R) command switch. Also have a look at man page for smb.conf, as the method for name look ups is defined there (The order too) The default order is lmhosts, host, wins, bcast for name look ups. I beleive that for bcast name lookups to work you need to allow bcast traffic too. ie you need to allow 192.168.0.255 port 137. If you don't want that, a quick fix is to try adding the 'myserver' name and IP to /etc/hosts .. Cheers, Michael
