Hi Francesco,
as you have not heared of it, it is unlikely that you use it. So I would
go for an mtu check. What is 'ping -M do -s 1472 login.plx.cineca.it'
saying, does it work?

Hi Robert:
francesco@tya64:~$ uname -r
3.2.0-4-amd64

I do not understand "tunnel". I use classical scp, passwordless (my pub
keys at the mainframe):
francesco@tya64:~$ scp -p
[email protected]:/gpfs/scratch/userexternal/fpietra0/P2f_accelMD_H2O_PLX/*30.dcd
/home/francesco/PLX
and "stalling" occurs randomly. I did not try with another box, where
jelly is installed. Also, I did not try either from the Linux prompt
(actually I us startx, followed by gnome-session. I am having those
problems from the gnome terminal). I never had such problems from a
French server at the Univ Picardie, but that automatically probalby uses
ftp (and it has to be used from the graphical interface).
Thanks
francesco

Hi Francesco,
what kernel version do you use? There is an unfixed (in mainline)
kernel bug in the tun device which might cause your problems (see
https://bugzilla.kernel.org/__show_bug.cgi?id=74051
<https://bugzilla.kernel.org/show_bug.cgi?id=74051> ). This will
only be a problem if you use a tunnel to connect to your server.

Hello:
Since a few days, scp downloading 500MB file from a
supercomputer at the
Italian center CINECA results quite often in
francesco@tya64:~/PLX$ scp -p
[email protected]:/__gpfs/scratch/userexternal/__fpietra0/P3f_accelMD_H2O_PLX/*__29.dcd
/home/francesco/PLX
npt_accel-29.dcd 3% 13MB
0.0KB/s -
stalled -
No problem with small files.
Check at CINECA resulted in no malfunction. The provider
(TELECOM ITALY)
says their adsl if percetly functioning. Actually, the speed, ca
600kb/s, is as expected (don't smile, Italy is at that speed; if
you pay
more, you can just hope to download at 1000kb/s, while out is always
impracticably slow).
My question is: can scp, as available from my installation on a
wheezy
amd64 box, be responsible?
thanks for advice
francesco pietra
