TTY Issue?

joe_91 — Mon, 17 Feb 2003 15:29:03 GMT

Hi:
I am logged in from home. I get connected to my server using a telnet (PC) session. when i login to a particular server as root, i am not able to do ll. it just throws junk. on the other servers it is fine. Please let me know how to solve this. Should i capture the tty from the working server. if so how? pl. help

Thanks

Joe

Hi

Sounds like stty

look at stty -a on one that works and on the one that doesnt.

Probably there is a difference in baud rate

Otherwise please define junk

Strange that only "ll" would have a problem...

Is it possible in the login profile for "root" you have hardcoded a terminal type (TERM variable) that has problems with Microsoft Windows telnet?

Hi Steve:

Thanks. When i do "ll" or "ls" it throws junk characters and i get the prompt back only after a ^c.

Thanks

Joe.

Almost certainly the ttyp settings are different on this server. You can probably change the parity, stop bits, or word length on your PC terminal emulator so that you can connect. Plan B. Examine the /etc/gettydefs settings for working hosts and compare to this host. Examine /etc/innitab, the last field corresponds to the /etc/gettydefs entry for this particular port.

Hi:

Let me make it more clear. All i am getting is a prompt. i can't do any commands. when i do it is throwing to stdout as a junk.

Thanks

Joe.

Hi Joe,

What happens to listings from *other* dirs?
Do an ll /tmp (or some other dir) BEFORE you do an ll in the home dir.

Is it possible that you have a file in your home dir that contains terminal control-codes in the filename?

If not I'd agree that it's a stty problem.

Rgds,
Jeff

I thought I was clear but here goes again. If you must talk to this box remotely today then your only option is to play with the tty settings on your PC emulator.
The likely candidates are baudrate, wordlength, stop bits, and parity - all of which can be adjusted on your PC emulator. THere are, of course, many combinations and permutations. I would start at 9600, 8,1,N then 9600, 7,2,E but it could be anything.

Plan C. If you can telnet to on of the 'good' hosts can you then telnet to the 'bad' host through the 'good' one?

Hi Clay:

Thanks. I telnet to the good one. From there i telnet to the bad one and my listing (ll) is gone.

Thanks

Joe.

Joe ... even though you cant get response from commands on the "bad server", you may still be able to type commands.

Once you get the command prompt, type:

stty -sane

and see if that works.

Also try:

stty -parity

I have had to do this dialing into systems remotely at times.
