SLED11 Sp2 iptables dump
This is a SLED11 specific problem and what happens are that if you copy a large file to the mounted client drive, the nfs kernel client will timeout;
[ 1176.992247] nfs: server localhost not responding, timed out.
However smaller files and other operations works as expected.
100Mb test file will hang, 1Mb test file works as expected.
Turning of the firewall on SLED11 fixes the problem and copying 100Mb file
works as expected.
Interesting tho, is that output chain accepts all from/to anywhere...
See attachment for iptables -L -m
Stumble upon this bug when testing 32bit SLETC client against SLED11 Sp3, however no firewall is enabled and the issue still occours.
I've seen something similar to this with a Solaris client and a Ubuntu 12.04 server. Something fishy is going on.
I reproduced with the following in a ThinLinc session:
$ dd if=/dev/zero of=testfil.1G bs=1M count=1024
$ cp testfil.1G ~/thindrives/tmp/
Here vncviewer stops receiving updates, sound stops playing, etc. Waiting ~10 minutes, the session often resumes itself.
Can reproduce this problem with a 545Mb file on Fedora 30 when moving or copying it to a local drive mounted from Windows 10.
Can reproduce both with build 6182 (4.10.1) and 4.8.1 clients.
This is the error I'm getting in the terminal when running "cp":
>cp: misslyckades att stänga 'thindrives/Desktop/tears_of_steel_1080p.webm': In/ut-fel
