Good morning :)

sbalneav: Scotty would you have time to revert that commit today, so that I would then ping the ubuntu-mate maintainer for an SRU?
14:22
<sbalneav>
I'll see what I can come up with. I'll have to talk to some of the devs.

<alkisg>
ogra_: I'm having a bit of bureaucracy from #mate-dev, would it be possible to pitch in on https://github.com/mate-desktop/mate-panel/issues/535? and mention that it's indeed not needed anymore?
16:36
(it's that gnome-panel patch about hiding the shutdown menu on thin clients)

<alkisg>
bennabiy: no, but I'd like to try out their null cipher
20:25
<bennabiy>
alkisg: It is pretty fast compared to stock ssh
20:25
I wondered about it for ltsp use
20:25
<alkisg>
Null cipher = 0% sshd cpu usage :D
20:25
While now it's possible to get 100% cpu usage for sshd even on i3/i5 processors, if clients have enough disk access
20:26
bennabiy: did you try it on ubuntu?
20:26
<bennabiy>
alkisg: debian and ubuntu
20:26
but not with the null cipher
20:26
<alkisg>
Did you compile yourself, or did you use a ppa?
20:26
or some .deb?
20:29
Hmm the version at https://launchpad.net/~yoda-jazz-kc/+archive/ubuntu/hpn-ssh is older than the openssh one provided in ubuntu repositories
20:29
So apt pinning would need to be done to keep it
20:30
(and, one should ignore the security updates there...)
20:31
And also this seems to be needed to avoid sshd restarts: http://unix.stackexchange.com/questions/313080/infinite-activating-state-for-custom-build-openssh-hpn-sshd-on-ubuntu-16/313159
20:36
<bennabiy>
compiled myself
20:37
granted I use it more on my debian servers, but I did get it working on 16.04
20:38
I do not currently have it on this machine though, I just realized, because I did a reinstall and never recompiled it.
