Login password prompt in upper case.


Kernel 2.6.21.5, Slackware 12.0
bash 3.1

Hi:
I have several times tried to log into my linux box and have seen the password prompt written in upper case chars. Can this be caused by something located on the other side of my connexion? Or by malignous software resident in my hard disk? Any hint will be welcome. Thanks.

Does this condition prevent you from logging in properly? Are you able to login even though the prompt appears in uppercase?

If you are able to login normally, don't worry too much about the prompt in uppercase chars. However, it is annoying to have something happening at random without apparent reason.

You should probably search though the files in /etc for anything that could affect the prompt, such as PS1 and PS2 prompts, and events which would determine which prompt is to be used.

Something like this:
Code:
find /etc -type f | xargs grep -i -A 3 -B 3 prompt | tee prompt
This will run a search for occurrences of the word "prompt" and show the 3 lines before and 3 lines after the occurrence, and write the output to a file called prompt, which you can study at your leisure.

My fault. I omitted the main fact. I have not been able to login at all in the two or three occasions when this has happened. I had never seen such a thing since I use linux, which is, by now, a long time ago. Also, perhaps "prompt password" does not mean what I intended to mean. I'll use an example:
Code:
root@darkstar:~# exit
logout
Welcome to Linux 2.6.21.5-smp (tty2)
darkstar login: root
Password: <here my password>
Since I began using Slackware, things were this way. But consider
Code:
root@darkstar:~# exit
logout
Welcome to Linux 2.6.21.5-smp (tty2)
darkstar login: root
PASSWORD: <here my password>
I have run the code you sent me and examined the output and, having centered my attention only in those files I considered that were more to the point, I did not find anything suspicious.

There have been several other strange behaviors of the system, that of the password being the strangest of all. Regards.
