Karaf and SSH timeouts
Out of curiosity, since this is driving me a bit batty because I usually
SSH into Karaf locally to tail the log, is there a bug in the SSH library
that Karaf uses to provide SSH access? The past few releases of Karaf,
4.1.13, 4.1.14 and 4.2.0 all timeout after a few minutes of being connected
via SSH to Karaf:
14:26:36.079 WARN [sshd-SshServer[20286265]-nio2-thread-1]
exceptionCaught(ServerSessionImpl[karaf@/127.0.0.1:63261])[state=Opened]
InterruptedByTimeoutException: null
I tried upping the timeout in the Karaf config which doesn't help. I
noticed a discussion in a different open source project (the name escapes
me at the moment) where they were having a similar issue and said it
started at 4.1.12. I was surprised to not see anyone else mentioning it,
so I'm just wondering if it's me. I would think this would be something
that would stand out to others very quickly. :) It happens no matter the
SSH client I use, or whether running Windows or Linux...

I would check the terminal settings + bouncycastle + JVM security first (even if
it should not impact the timeout IMHO).

Re: Karaf and SSH timeouts
Posted by Ryan Moquin <fr...@gmail.com>.
If you can point me to where in Karaf would be a good point to investigate,
I don't mind doing some preliminary debugging of this, especially because
it's such a pain in the rear for me. I know you guys probably have a lot
of your plate and this issue is more of a severe annoyance than anything
else, so I'm sure it doesn't really rank super high on list of priorities.

Re: Karaf and SSH timeouts
Posted by Ryan Moquin <fr...@gmail.com>.
One more thing that might be helpful, my bitvise client reconnects... so
there is a set of logs where it's been connecting and getting disconnected,
looks like it's happening every 10 minutes, I wasn't doing anything with
Karaf during that time:
18:25:48.014 WARN [sshd-SshServer[6e85ec8]-nio2-thread-1]
exceptionCaught(ServerSessionImpl[karaf@/127.0.0.1:49332])[state=Opened]
InterruptedByTimeoutException: null

Thanks for the update.
Let me try to reproduce this behavior.

Re: Karaf and SSH timeouts
Posted by Ryan Moquin <fr...@gmail.com>.
Yes, sorry, 4.0.12. Yes, with both the Karaf client and an OpenSSH client
I see this happen. Let me just re-verify that if I start up karaf with
absolutely nothing in it and ssh to it locally that it times out. Want to
make sure no bundles are clobbering anything. The logging gets messed up
periodically because camel pulls in pax-logger-log4j2 which breaks the
logging and then I have to reconnect my ssh client, if it's still
connected. I think this is something different though.
Actually, I think a bug was logged for this by OpenHAB (that was the
project), here is the thread where they discuss what sounds like the exact
same thing I'm seeing. They mention it happening after 30 minutes, which
is what the Karaf timeout is configured for, but then someone else mentions
it happens after a few minutes consistently...
https://community.openhab.org/t/timeout-in-karaf-console/35443
I've tried different SSH clients with Karaf to see if there was any
difference just in case. If I turn on keepalive in my bitvise ssh client,
it seems to stay connected a lot longer, but it sends a keep alive ever 20
seconds and the interval isn't configurable, which makes the logs fun to
look through :)

Re: Karaf and SSH timeouts

Hi Ryan,
Are you using the Karaf client or OpenSSH client ?
You just type log:tail ?
I didn't notice such timeout.
By the way, I guess you mean Karaf 4.0.12 (not 4.1.12) right ?
Regards
JB
