Re: FreeBSD 7.0-STABLE: "mount_nfs" vs "mount -t nfs": problems with second one, UDP timeouts and ICMP ports unreach?!

Adding `-o -c' to mount (to pass `-c' to mount_nfs) helps. But I'm very curious WHY mount_nfs, called directly, work WITHOUT `-c'... -- // Black Lion AKA Lev Serebryakov <[EMAIL PROTECTED]> ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"

FreeBSD 7.0-STABLE: "mount_nfs" vs "mount -t nfs": problems with second one, UDP timeouts and ICMP ports unreach?!
I have two hosts: host A (FreeBSD 6.3-S) and host B (FreeBSD 7.0-S, freshly installed). Host A exports "/usr/ports" to host B via NFS. Mount with "mount_nfs" works well: b# mount_nfs a:/usr/ports /usr/ports b# ls /usr/ports [---SKIPPED---= b# But mount with "mount -t nfs" FAILS: b# mount -t nfs a:/usr/ports /usr/ports [udp] a:/usr/ports: NFSPROC_NULL: RPC: Timed out [udp] a:/usr/ports: NFSPROC_NULL: RPC: Timed out ^C b# tcpdump on A shows VERY strange picture: b.960 > a.sunrpc: UDP, length 56 a.sunrpc > b.960: UDP, length 28 b.820 > a.nfs: 40 null a.nfs > b.820: reply ok 24 b > a: ICMP b udp port 820 unreachable, length 36 b.912 > a.sunrpc: UDP, length 56 a.sunrpc > b.912: UDP, length 28 b.973 > a.nfs: 40 null a.nfs > b.973: reply ok 24 b > a: ICMP b udp port 973 unreachable, length 36 You see? b answer with "UDP port unreachable" on each RPC reply! There is NO any firewalls on B. And, I repeat, it WORKS when I call mount_nfs directly in a moment! Main problem is, that "/etc/fstab" is processed by mount, and NFS mount hangs up on boot, as shown above :( -- // Lev Serebryakov ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
