Problem with NFS, everything freeze
Regards. I've got a problem with nfs. There are 2 servers. A and B. On server A I export one dir and start nfsd, portmap, mountd. On server B in mount A's exported dir. I begin to copy approxymately 40Mb up to A from B. At 30Mb the copy brokens and everything freeze on server B. B replyes to ping but nothing else. I waited 8 hours but nothing happened. I had to ask a restart for server B. For the most part it always happens. But why? Server A, B is OpenBSD 3.6 but I tried with 3.6-3.5 and the way around. They always freeze. I feel so uneasy..:/ The mount option was: serverA:/dir/ /mnt/nfsnfs rw 0 0 How can I avoid the feeze? I want to use nfs, to omit scp ( daily mail backups, sys backups and so on ) -- Adam Papai D i g i t a l Influence E-mail: [EMAIL PROTECTED] Phone: +36 30 33-55-735

are you running pf? are you scrubbing on an interface? On Wed, Jul 27, 2005 at 08:00:27AM +0200, Adam Papai wrote: Regards. I've got a problem with nfs. There are 2 servers. A and B.

Re: Problem with NFS, everything freeze
hey, yep, i made the same mistake first up too... from the pf users guide One reason not to scrub on an interface is if one is passing NFS through PF. Some non-OpenBSD platforms send (and expect) strange packets -- fragmented packets with the do not fragment bit set, which are (properly) rejected by scrub. This can be resolved by use of the no-df option. Another reason is some multi-player games have connection problems passing through PF with scrub enabled. Other than these somewhat unusual cases, scrubbing all packets is highly recommended practice.

Steven Manos said: hey, yep, i made the same mistake first up too... And did your system freeze as well like mine? Thanks anyway. I'll try this at home with 2 test NFS servers. ( of course with 2 openbsd ) I hope it will work. If not, I'll be sad. -- Adam Papai D i g i t a l Influence E-mail: [EMAIL PROTECTED] Phone: +36 30 33-55-735
