hi Ricky,
in my first mail I mentioned

Last week I had to install Matehematica 5.2 in my system for which I  had to make certain canges in /etc/fstab file (I had to add user, exec in the first line) .

I removed "users, exec" and now there is no problem in screen lock.  I don't know the reason, bu t it worked. Any insight into the subject ?

no, no, even the user who has locked the session is not able to log in, the error is that the PW is not correct.

Dear friends,
I have FC6 in my system. I have the root PW, and two other users are using the system with different login. Last week I had to install Matehematica 5.2 in my system for which I  had to make certain canges in /etc/fstab file (I had to add user, exec in the first line) . After the installation of Mathematia
when any user locks screen and then tryes to unlock screen the pw is not recognized. He has to kill the session and then login again. when there is a fresh log in there is no pw problem. I am not able to understand the problem. Please suggest the solution.

Thanks In Advance.
Srikant.

Hi Ricky,
Thanks, thanks and thanks a million, it worked. I copyed the whole folder to root home folder and the ./MathInstaller command worked. I am now working in mathematica.

If you have time can you please explain what was the error. I am not a new user to Linux, but I have the root pw now. I realy want to understand Linux properly. Can you please suggest the best way to approach so that I will not waste 3 days for installation of any essential software.

Follwing is the error I got for "fdisk -l"
bash: fdisk: command not found

Thanking you again I remain
Srikant

Dear Ricky,
the  fdisk -l command is not working in FC6 , is there any other command for it ? My Mathematica installation folder is in cd drive only. Shall I copy them to root folder then try ? let me try to  "user" and get back to you.

Thanks for your help.

no it didn't  worked. it is showing same error.

how to proceed next ?

Dear Friends,
I have just  installed Fedora Core 6 in my system. For last few days I am trying to install Mathematica 5.2  in it. I am jumping to the folder where MathInstaller file is there and when running the command ./MathInstaller I get the following error message

bash: ./MathInstaller: /bin/sh: bad interpreter: Permission denied

I am doing all  this as root, still I am not able to install Mathematica. I searched in google for help. In one website there is a indication that this may occure due to improper mounting of cd. I tryed to use  mount  and unmount command in shell, both of which are not recognizable in FC6. I have already wasted lot of time in it. PLEASE HELP.  Until unless I install Mathematica in FC6 I can't work then I have to switch to Windows XP which I HATE the most.

Dear friends,
I am new to both linux and this website so excuse me if I am posting the question in wrong group.

the base URL of my YUM is following
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/$releasever/$basearch/os/
mirrorlist=http://fedora.redhat.com/download/mirrors/fedora-core-$releasever
which is wrong,  can ne1 suggest correct one ?
Thanks in advance.
