Subject: Can't connect to Ubuntu box
Print | Individual message | Show original | Report this message | Find messages by this author

I can connect just fine from my WinXP machine using PuTTY, but Connect Bot
gives me:

---------------------------------
Connecting to 192.168.1.53:22 via ssh

Connection Lost
Connecting to 192.168.1.53:22 via ssh
The operation timed out
The operation timed out
---------------------------------

The PC is wired, and the phone is connected via WiFi. I'm sitting at home
on my home network, and I get a nearly instant connection from the PC.

Suggestions? What other info do you need to help trouble shoot?

TIA

Install aLogcat and look at what connectbot has to say in the log

Looks like there's an error from Java on a time out, but doesn't seem (to
me) to indicate what's causing it. Do I need to change settings in aLogcat?
Level is currently Verbose, and Format is Brief.

Thanks a bunch!

OK. can you try to connect from the phone to  192.169.1.53 by some
other means? maybe it has a web server, or maybe just ping?

Or use telnet protocol to connect to ssshd (port 22).  Do same from desktop to see what to expect.

I sure can. I'm running XBMC on the Ubuntu box, and I use the XBMC remote
control app on the phone to connect to it. Also, I just tried to ping, and
was getting <2ms response times.

I attempted to telnet to port 22. I got no response on the phone or desktop
- it said "SSH-2.0-OpenSSH_5.8p1 Debian-7ubuntu1" and stared back at me.

The response is as expected.  It proves that you have gotten a text string from the sshd server! The SSH version string.

Not sure what happened to my original response...

I take it, then, that this is a good sign. Is there anything further I
should pursue on this path?

You didn't quote what you are responding to but I take it to be mine.

I have never rebuild ConnectBot nor look at the source, but here's my
guess.  The bottom most layer in ConnectBot that talks just slightly
above the TCP level is working fine in that it is able to communicate
and exchange data with the sshd server.  If indeed as your logcat suggest
there is an exception in the Java code, it is likely in the higher level
dealing with the ssh protocol.

Without the coder taking a closer look, we really don't know.

But if you can/want to try difference version of the sshd server, say
lower than 5.8, even just briefly, may be some versions will work.
Alternatively you can try 5.8 on another Linux machine, say on a
different distro.

Bear in mind that I'm just suggesting what I can think of, not necessary
what you should do.  It may be more productive to wait for a volunteer
coder to take a look.

Sorry, l00g33k, I'm looking at the website where the conversation is neatly
threaded, so I deleted the very long quote string. Yes, I was responding to
you.

You've gone over my head with this, I've never delved much into the 7
different layers involved in communication, so I wouldn't have a clue where
to start looking, I'm not enough of a Linux geek to want to mess around
with trying another version of SSH - especially since this is on my HTPC,
and any time it's been unavailable, there is a major ruckus at the house!
8-(

I appreciate your thoughts, hopefully someone else will have some
suggestions, or be able to delve into the code to see what's up.

Any other suggestions on what to look at? Would it be helpful to turn up
the level of what's reported in aLogcat?

Thanks
