I have been getting the following errors: [2002/05/12 12:39:22, 0] libsmb/nmblib.c:send_udp(755) Packet send failed to 213.37.53.255(138) ERRNO=Operation not permitted and a bunch of others!!! On my network I have 2 interfaces my local network and my ISP's network. I was restricting all udp,tcp 137 and 138 via iptables onto my ISP's network mainly because I don't want none of that traffic being transmitted on that interface. Then I started receiveing all of these errors in my nmb.log I looked in the mail lists and saw that other people were having similar problems. After making the following changes (smb.conf) my errors have stopped: # Configure Samba to use multiple interfaces # If you have multiple network interfaces then you must list them # here. See the man page for details. interfaces = eth0 bind interfaces only = yes As you can see I added the "bind interfaces only" and set the interface to only eth0 (my local network, eth1 is my ISP). There are a fews ways to configure this but this seems best for me. Good Luck, Earle Nietzel P.S. Any replies should be sent to me as I am not on the mailing list.
