Since a couple of days I have a very strang thing... Machine-A : eth0 192.168.5.37 (linux) eth1 x.x.5.37 Machine-B : eth0 192.168.5.10 (win2k) eth1 x.x.5.10 eth3 not configured Machine-C : eth0 192.168.89.10 (win2k) Machine-B was mounted on Machine-A on /mnt/d (through 192.168.5.10) Machine-C was mounted on Machine-B on /mnt/c (through 192.168.89.10) After a power-failure on our switch, /mnt/d can be mounted but I can't read anything: ls /mnt/d freezes, and in smbmount.log I get: [2005/12/21 11:03:06, 0] tdb/tdbutil.c:tdb_log(725) tdb(/var/cache/samba/gencache.tdb): tdb_lock failed on list 10 ltype=1 (Bad file descriptor) However some things are working: df -h //192.168.5.10/Logfiles 38G 8.5G 29G 23% /mnt/d If I mount Machine-B through the other network-card it works just fine. --> this assumes the problem is within the 192.168-network or cards. Mounted Machine-C on Machine-B: no problem Mounted Machine-C on Machine-A: no problem --> the card of machine A+B+C must be fine Then fixed a cross-cable between Machine-A en B (192.168-cards), and it also works just fine: --> assuming the problem is within the switch or cabling. But this is very strange, cause the mount of Machine-C is also through that switch and cable. Removed all the cables, tried another switch: still no response! After this I assigned eth3 on Machine-B with the address of eth0, and now it works fine. Can somebody give me a clou what's going on, or where to look? Best regards, Pascal
