[Bug 1417157] [NEW] scp transfers stalls and aborts because of SACK packages with invalid state

 

Public bug reported:

There is an existing bug report at red hat websites that exactly
discribes what happens to my ubuntu server installation.

https://bugzilla.redhat.com/show_bug.cgi?id=161898

I can confirm that this bug is affecting ubuntu 14.04 servers as well as
debian installations we are running in our university network. I can
further confirm that all workarounds stated in the last post by Chris
(2014-02-20 12:17:53 EST) work and he nailed pretty much all my findings
on our servers. So please read the last post by Chris.

There is probably  also a relation to this launchpad issue: Bug
#1388786, but I'm not shure about that. Is there any way you can provide
me with a linux kernel that solves this issue. I'm willing to test and
report here.

Thanks in advance
