Hi list! I already googled and grouped for that strange problem, so I hope to find here some answers. Since I updated to SuSE 7.3/ SuSEfirewall2 / protect from internal = yes ... Port 139 internally open, it somethimes occurs a problem connecting to the samba server (domain master) from any windows client: There is even nohting about a connection in the smb /nmb logs except if the hosts were listed in /etc/hosts. ^^^^^^ In the firewall log I've found some drops from the client ips connecting to the server (PROTO = UDP; SPT = 137), but this should nothing had to do with it? So I finally solved a part of it, but don't understand it... is this SuSEs understanding of security? Please excuse my very bad english. best regards, Vincent Kurtz
