I migrated a samba PDC (and WINS server) from 3.0.7 on Fedora Core 1 to new hardware running 3.0.14a on Fedora Core 4 using the procedure outlined in the Samba by Example docs. It appears to have been a success. I do see log messages like the following though: Feb 21 09:10:45 gecko nmbd[2450]: [2006/02/21 09:10:45, 0] libsmb/nmblib.c:send_udp(790) Feb 21 09:10:45 gecko nmbd[2450]: Packet send failed to 192.168.254.50(138) ERRNO=Operation not permitted There is no corresponding kernel iptables log entry so I don't think this communication is being blocked by the firewall. Also the firewall explicitly allows udp to port 138 on the local intranet. What else could it be and is it anything to worry about? Thanks, Mark Nienberg
