Hi, since december 1999 we have successfully running Samba on HP-Unix 10.20 with nmbd version 2.04b. Suddenly it's no longer possible to connect from Win9x clients - a connect from NT-Clients still works, but connection establishing is very slow. Here is an excerpt from the log.smb file for a connect request from a Win95 client: [2000/03/22 16:54:36, 3] smbd/process.c:(974) priming nmbd [2000/03/22 16:54:51, 3] lib/util_sock.c:(645) sending a packet of len 1 to (127.0.0.1) on port 137 of type DGRAM [2000/03/22 16:54:51, 4] lib/time.c:(110) Serverzone is -3600 [2000/03/22 16:54:51, 3] smbd/process.c:(615) Transaction 0 of length 72 [2000/03/22 16:54:51, 2] smbd/reply.c:(95) netbios connect: name1=CMGGE60 name2=DE-ESC-LAP4408 [2000/03/22 16:54:51, 5] smbd/connection.c:(127) trying claim /var/opt/samba/locks STATUS. 100000 [2000/03/22 16:54:51, 0] lib/util_sock.c:(889) getpeername failed.

Exiting The Win95 client then shows a popup saying "\\Cmgge60 is not accessible. The network is busy." I performed the tests described in Diagnosis.txt. Test 1 to 4 succeeded. I got problems with TEST 5 (nmblookup -B de-esc-lap4408 '*'): After 1 or 2 minutes the program exits with Sending queries to 0.0.0.0 10.48.191.210 *<00> The IP-address is the one of the Samba server not the one of the client! The same happens with a query for a NT client. Is it a sudden name resolving problem? In this moment I have no idea how to proceed. The problem arose over night - no configuration files have been modified, everything looks like before - nevertheless something in our network environment must have changed, but what? Is there someone who has a usefull idea? That would be great! Regards, Gunter Reinhard
