:This is yet another problem that we have run into here. If you check the :digest for -hackers it was reported awhile ago (mike smith even cc-ed it :to security since it may have been a kernel stack overflow) . Anyway, the :problem is that IRIX defaults to 32K packets on TCP NFSv3 mounts, and :16K on UDP NFSv3 mounts. I recommend using UDP and setting rsize=8192, :wsize=8192 in your amd maps (as we do now, no problems at all). : :-- :David Cross | email: crossd@cs.rpi.edu :Systems Administrator/Research Programmer | Web: http://www.cs.rpi.edu/~crossd Ah ha! Yes, 32K packets will certainly screw up NFS under FreeBSD. We need to fix that panic to have it simply drop the packet, I guess. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
