ssh just stalls on login

When I try to log into my server via ssh, after I type in my password it just sits there forever.

I think it has something to do with the whole pty thing (running 2.6.4) but I'm not sure. I enabled whatever I could find in the kernel config relating to ptys:

Device Drivers -> Character Devices -> Legacy (BSD) PTY support
File Systems -> Pseudo Filesystems -> /dev/pts Extended Attributes

Is there something I'm missing? I thought there used to be another option in filesystems that was just "pts filesystem" or something, but I don't see it here.

2 questions

1) is there handshaking continuouslygoing on, or is it just died?

2) Did you try to ssh to the another server to make sure the client side is working?

I'm not sure what you mean exactly by it continuously handshaking, but yes my ssh client does work. I can connect to other ssh servers. When I try to connect to my own this is what happens:

bash-2.05b$ ssh bogo.ath.cx
bogo@bogo.ath.cx's password:

Yeah I have typed in the password, and it'll just stay at that point for infinity until I close the terminal window (ctrl-c/d doesn't do anything).

try

Well 192.168.1.1 would be my router which denies ssh, but if you were suggesting to try a different username on my server, that doesn't work either. Typing in an invalid username/password (as well as an invalid password for a valid username) will inform me that the password is invalid. Whenever I'm actually authenticated it's just not giving me a terminal.

if you try what I suggested, do you get a password prompt.

of coz the username/password both gotta be valid.

Yes... I get a password prompt... it's just that after I type in my password I don't get a terminal...

From the server, can you ssh to localhost?

Do you have this in your kernel config:
#
# Non-8250 serial port support
#
CONFIG_SERIAL_CORE=y
CONFIG_UNIX98_PTYS=y
CONFIG_UNIX98_PTY_COUNT=256

I had the same problem, and it is related to some kernel config, but I don't recall exactly which one.

Well... in my config it says CONFIG_LEGACY_PTYS and LEGACY_PTY_COUNT=256, instead of our beloved unix98 ones. Just for kicks I tried adding the config line pertaining to unix98 ptys and it said that was invalid. I'm guessing in 2.6.4 they changed something?

Also, sshing to localhost on my server doesn't work.

Try booting the livecd with the 2.6 kernel and grab the output of /proc/config.

I'm having the same problem, I think after upgrading the client machine's kernel to 2.6.4-rc1.

I'm working on it but I'm not too confident I'll find a solution so I'll keep watching!

I had that same problem with one of my servers too, only this was happening in the 2.6.3 kernel. I upgraded to 2.6.4 and everything is hunkey-dory.
Perhaps if you were do try the 2.6.3 kernel you may be able to ssh to it?
