Pseudo Terminal Problem

gabsik · 07-19-2008, 06:01 PM

I run debian lenny and i'm having issues with all the terminals avialable . When i launch kde konsole or gnome-terminal it says:

Code:

Konsole is unable to open a PTY (pseudo teletype). It is likely that this is due to an incorrect configuration of the PTY devices. Konsole needs to have read/write access to the PTY devices.

With an another console it also says:

Code:

Cannot open /dev/ttyS0 : Permission denied

With apt-get i was installing some softwares and i saw an another error asking me if /dev/pty was mounted .....

Hmm... I can't even find any 'pty' on my system. As for the 'ttyS0', I get this:

ls -l /dev/ttyS0
lrwxrwxrwx 1 root root 5 Jul 20 2008 /dev/ttyS0 -> tts/0

ls -l /dev/tts/0
crw-rw---- 1 root dialout 4, 64 Jul 20 2008 /dev/tts/0

Did you check the permissions on your serial port so anyone in the 'dialout' group can use it?

I'm still wondering why your console wants a pty or ttyS0 though.

It's not on my system either .
From the shell if i use the completition it says :

Code:

/dev/fd/0 no such file o directory

this error comes out just after i press the completition tab , it's a fresh debian install ... debian sid .

What completion is this? What command are you trying to complete?

If i try to complete any command , i think it's a bash script issue . Or /etc/bash.bashrc or /etc/bash_completition .

Forgetting about X window and KDE, what happens if you log in at the console?

What happened since it was working?
Did you update udev?
apt-cache policy udev

if i launch konsole , gnome says :

Code:

Cannot open /dev/ttyS0 : Permission denied

If i try to connect to this host through ssh the command gets stuck after it asked the key's password.
In the 'real shell' if i use completion tab on any command it says of a /dev/fd/0 as sayd above .
It is rally strange , whatever terminal , or form of console bash having to do with devices like /dev/pty .

Code:

Konsole is unable to open a PTY (pseudo teletype). It is likely that this is due to an incorrect configuration of the PTY devices. Konsole needs to have read/write access to the PTY devices.

That's all i can say i will try to post more debugging output next posts
Thanks

Server refused to allocate PTY
