My Red Hat Enterprise Linux 4 system does not boot and stalls


Hello everybody

I am using Red Hat Enterprise Linux 4 on a single machine (an HP Proliant) and recently I installed the Intel Fortran Compiler as 'root'. Trying to make the newly installed compiler available to every user, I added 'source /opt/.../ifortvars.sh' both in the 'bashrc' and 'profile' files in the 'etc' directory.
I guess I did it wrong, because the system stops loading the files and everything else.
To be specific, it goes thru 'Grub' then loads a few things, but when it gets to 'Hal Daemon' right after that its stops, presumably for 5 minutes but it actually stalls for good and I have to turn the power off and on to restart.

My questions are: 1)How can I fix this problem? 2) If I cannot fix this, and reinstall the same version of Linux will I loose my data and would the user accounts disappear?

Your help is most welcome.
Regards, Saadi

Boot to single-user mode and undo your changes.

You should be able to just re-use existing partitions and NOT format them and existing data should be safe, however it's better to get a live distro and properly back it up.

First however I would suggest going into "Interactive mode" via I during boot and skipping most not needed services, Atleast then you can figure out what service is broken if any of the ones you need make it hang or roughly where about it occurs anyway.

Red Hat Enterprise Linux 4 is old

5.0 is dated March 14 2007, and they are now up to 5.3 so I expect 4 is no longer supported.

Perhaps you should get your system up to date?

Red Hat has roughly a 5 year support on all releases so 4 is still very much still supported. Also it costs to upgrade to newer versions and can cause issues. Infact I believe RHEL 3 may still be supported... RHEL licenses cost alot, Red Hat looks after their paying customers.

RHEL is a seven year life cycle.

RHEL 4 will be supported through at least 2012. (FWIW, my department runs only RHEL 4 in production.)

I stand corrected. By yourself, and r3sistance

Maybe I should check it out.
