It's only a problem with hpn and openssh-6.0_p1, as discussed in the bug
report.

But it stalls and blocks so much more quickly with it on :)

Video playback and CPU optimisations go hand in hand.

One video I have had for a long time, I could never play it at all on
any of my computers and I could not beleive what I saw next...
I got a new PC and thought to give it a try.  It worked painfully,
skipping and using 100% of one of my CPU cores.  I was sad and thought
this video might have been corrupt. After a wave of cleanup, I had
removed all CPU optimisation flags from my make.conf (I was originally
negating many, like -sse, etc, so I left it "to my profile" to choose
what was needed) and recompiled everything.  After that, the same
movie played in the best quality I had ever seen and CPU usage was
below 5%   I was even able to open 12 movies (4x3) all playing at
the same time (this was unthinkable before I optimized my system).
Anyway, keep in mind that my particular starting scenario was that I
had "un-optimized" it long ago!

Good luck!

Funny how "hpn" is supposed to enable "high performance". :-D

Well, openssh-5.9_p1-r4 
flag: "hpn" on by default and ssh is working without a problem.


If I were you I would open a bug.

I don't know, haven't used gentoo sources in ages. I don't need fb 
beautification, zcache, alps or livecd goodies. I like to be as close to 
upstream as possible, so bug reports are taken seriously.

vanilla-sources work reliably with that annoying io-stuff. But no matter which 
kernel I tried, ck, zen, gentoo, love etc pp that annoying io-stuff was always 
there.. so no reason at all to use a patched up kernel.

I use tftp-hpa and it works well for me.

Well a small web-server is going to handle the POST headers for you -
you're not going to have to write everything from scratch.

Yes it is, search b.g.o.

The problem is caused by the server running openssh-0.6_p1 with the hpn
USE flag, which is enabled by default. Either downgrade to 5.x or
re-emerge with USE="-hpn". I did the latter and everything is working as
it should now.

Well, not everything, my knee is still shot but SSH works :(

Sorry no answer, but I also saw this when using scp. I wasn't sure what
it was. But you're not alone... ;-)

Maybe we should just downgrade?

[gentoo-user] ssh stalls - please help

[Helmut Jarausch]

Hi,

probably since I've emerged openssh-6.0_p1 and/or git-sources-3.4_rc? I  
have problems with ssh.
scp as well as filezilla as well as  rsync -e 'ssh' stall when  
transmitting a somewhat larger file.

This might be as few as 500 Kb on a slow network (256 Kbit/s).
But it occurs on a fast network (100 Mbit/s) as well, when transmitting  
a larger file.


ssh not only stalls but seems to hang indefinitely.

Is this bug known and is there a work around?

Many thanks for some help,
Helmut.
