See? The laptop, with both firewalls down, does not see those packages. And I'm working all the time remotely from the deskop on the laptop, no network problems detected. I have pings running all the time from both sides, no losses.
Those packages are removed intentionally by something.

Ok, so the nfs tcp packages from the laptop fails. If it was a generalized failure, nfs udp packages would be lost, too, and I have sendt and received many megabytes over it yesterday, over nfs 3. Or tcp packages from other services. It makes no sense :-/
The laptop was connected via wifi, the server on cable; the wifi packages go through the router cpu part, the cable only over the switch part of the box. Now, I have connected the laptop on cable, firewalls up, and tried: instant connection, nfs version 4: minas-tirith:~ # date --rfc-3339=seconds ; time mount -v /var/cache/zypp/nfs_packages/ ; date --rfc-3339=seconds 2013-07-17 20:18:31+02:00 mount.nfs: timeout set for Wed Jul 17 20:20:31 2013 mount.nfs: trying text-based options 'vers=4,addr=192.168.1.14,clientaddr=192.168.1.130' 192.168.1.14:/data/storage_c/repositorios_zypp/ on /var/cache/zypp/nfs_packages type nfs (rw,noauto) real 0m0.566s user 0m0.001s sys 0m0.006s 2013-07-17 20:18:31+02:00 minas-tirith:~ # Thus, it is the router fault. The router wifi eats SYN ACK 870 :-( [...] Well, now it works on wifi too. :-O I did two things. One, I rebooted this morning, to Windows (twice), and to openSUSE 11.4 again. Then, I removed two routing entries: In the desktop, a rule pointing to the laptop: minas-tirith.va router 255.255.255.255 UGH 0 0 0 eth0 In the laptop, the reverse one: Tecontar.valin router.valinor 255.255.255.255 UGH 0 0 0 wlan0 These were absolutely necesary with my previous router, there was no connection without it. But the new router, contrary to my thoughts, doesn't, and in fact, breaks. Why it breaks eating some packages, I can not imagine. So, now, nfs4 works, with tcp, instantly! minas-tirith:~ # date --rfc-3339=seconds ; time mount -v /var/cache/zypp/nfs_packages/ ; date --rfc-3339=seconds 2013-07-17 21:05:58+02:00 mount.nfs: timeout set for Wed Jul 17 21:07:58 2013 mount.nfs: trying text-based options 'vers=4,addr=192.168.1.14,clientaddr=192.168.1.129' 192.168.1.14:/data/storage_c/repositorios_zypp/ on /var/cache/zypp/nfs_packages type nfs (rw,noauto) real 0m0.091s user 0m0.003s sys 0m0.007s 2013-07-17 21:05:58+02:00 minas-tirith:~ # - -- Cheers, Carlos E.
