Hello; This is the first time I have tried to ask for help working with Samba, so please bear with me. I have been a subscriber to the newsgroup for a while and have appreciated all the helpful information. I have had a Samba server in my office network for about a year or so and have been very pleased with its operation and performance. Recently, I have decided to put together another Samba Server as a "backup" server in case our main one goes down for any reason. I have configured it virtually identical to the original server. The major difference being that the original server was with Red Hat Linux 6.2 and the newer backup server is using Red Hat Linux 7.0. When I reboot or power cycle the new backup server, everything works just fine, all my other computers (mainly NT boxes) can log into the backup server and share files fine for about an hour or two. Then, for no known reason, all connections to the backup server fail with a message "Network Path Unavailable", and I can no longer "ping" the backup server from any other network computers. Nor can I ping from the backup server to any other computers. However the backupserver can ping itself fine, it just can't get out. If I reboot or power cycle the backup server, the ability to communicate with the other computers in the network is restored..............for awhile (hour or two), and then the same problem occurs again. It is almost as if there is a setting or configuration that is set to somehow "turn off" my network card in the Samba backup server. I realize that this may not be a Samba issue, and is more likely to be a networking problem, but short of replacing the network card (which was working just fine prior when the same computer was an NT box), I don't know what to do. Is there any Samba or linux configuration(s) that anyone has any suggestions on trying. Thanks in advance for anyone's time and help. Sincerely, Bill Hayman -------------- next part -------------- HTML attachment scrubbed and removed
Hello Bill, Off the top of my head, I gotta say this is in all likelyhood NOT a samba problem. The disconnecting from the network sounds like it is the result of a cumulative phenomenon, possibly stemming from your NIC. I can only suggest to follow your instincts and change the card. I would also check dmesg, ifconfig, /etc/modules.conf, /var/log/messages, syslogs and netstat for any clues. I would also be interested to hear any results you can find regarding this, as I have run across something similar once before with no resolution. -- Keith Mastin kmastin@beechtree-its.com BeechTree Information Technology Services Inc. 137 Laird Drive M4G 3V5 Tel(416)696-6070 http://www.beechtree-its.com
Hello Keith; Thank you very much for your time and input. You were correct in that it was not a Samba problem. The nic I was using in the backupserver machine was a Kingston KNE110TX/110B PCI type network card. I thought, after checking the hardware support list that it was a supported nic in Red Hat 7.0. Apparently I was wrong. After another 4 hours of attempting to locate some type of setting or configuration file that might be the culprit, I decided to change out the nic and I substituted one my old "faithful" nics. I switched to an older Realtek PCI card and that appears to have done the trick. everything has been working nicely now for about 14 hours which is far longer than anything prior. If the problem should crop up again, I will keep you posted. I hope this is helpful to you and I thought it was interesting that you had a similar problem crop up before. Thanks again for your help, I am very impressed at the quality of information and people associated with this group. Wish others were as good.

Hi, it could be a DHCP/Route problem. It depends if you are running DHCP but I would try this. Check the route table, see if it's changed after the network goes down. Maby the RH7 receives a DHCP request and processes this and changes you route table? I would suggest using static addresses in servers. Check your interface card. Is it still there and functional? Do you have any 'clean up' deamon runing? Rebooting the server would not be necesarry. Just try to do one thing at a time. And see if it worked again after that one single action. Riesd
