If there's a more appropriate list to post to, I apologise, but I am not a list member. I'm having a bit of a problem doing simple copies over an NFS mount. The client is running Linux (2.6.11), and the server is running Solaris (5.8). When I first boot the client, getting NFS directory listings works just fine. But the instant I try to copy a file (to or from), the NFS mount hangs. While I can still do other network activity (even rlogin to the server), any NFS access I try to do after that point hangs, including directory listings. I have had this same client and server working flawlessly for years. The only change is that the client is now on a VPN (Watchguard SOHO box). However, I have a Sun machine on the same VPN network segment, and it can copy files with no problem, so it's not the router/SOHO that's blocking anything. (NIS and DNS also work just fine for both machines.) Also, after it hangs like that, I cannot reboot the machine normally. When attempting to unmount the network filesystems, the shutdown hangs, and I have to hard-reset the machine. Is there anyone who could please help me to debug this problem? As far as I know, I have NFS setup properly, but I don't know enough about it to know what options I might try. I don't even care if the fix degrades performance; I just want it to not hang. Does anyone have any ideas? Thanks very much in advance!
