anyone Perl guru??
 

I just installed Perl and DBI on my Suse box. When I test my DBI (perl -e 'use DBI;') from command line using regular account I get this message:

However, the same command run as root works just fine. I assume that this is file permissions problems, isn't it? cdruser1 belongs to "users" group and permissions for DBI.pm file reads like that:

cdruser1@cdr1:/usr/lib/perl5/site_perl/5.8.8/i586-linux-thread-multi> la

Any ideas what would fix the problem? change file permissions, or primary group for cdruser1? any ideas are appreciated. Thanks

I think you just answered your own question.
Yes it is, change the permissions on the file so that your user (cdruser1) is able to read the file. Currently the user and group permissions are both set to root.

So as root, use chown to change the owner to cdruser1. or chgrp to give a group that cdruser1 is in permission to read the file.

Here is info on chown - http://en.wikipedia.org/wiki/Chown
Here is info on chgrp - http://en.wikipedia.org/wiki/Chgrp
Here is some info on another command to alter the read/write/execute permissions on a file - http://en.wikipedia.org/wiki/Chmod

Thank you for fast reply. I tried doing something else before your suggestion, and I am surprised that it didn't work. I added cdruser1 to wheel group and enabled %wheel ALL=(ALL) ALL in sudoers file. But I still got the same error. Anyway, about permissions of DBI.pm. As soon as I changed the owner, the DBI test worked out fine. But I still have question. When you look at the permissions -r--r--r-- 1 root root 289975 2007-10-16 08:42 DBI.pm, why cdruser1 can't read DBI.pm during the test if "others" do have read permission. Does DBI.pm must be executed, but not just read? Thanks for your help.

Oh, another weird problem. Maybe someone will know that. I exported two variables in /etc/profile:
When I login as cdruser1, both variables exit. When I "su" to root, LD_LIBRARY_PATH just disappears even though ORACLE_HOME still works. Switching back to cdruser1 with "su" doesn't solve the problem; LD_LIBRARY_PATH still doesn't work. Again, after reboot everything works just fine until the first "su". Does it have something to do with wrong file for loading variables? But I still don't get how only one of those variables disappears... Unless there is some other place where ORACLE_HOME is exported. By the way, I use TWM (tab windows manager) if that makes any difference...

When you su, you don't take root environment variables (user environment variables are preserved). You need to use su - or sudo -s so user environment variables will be read from his .bash_profile or .bashrc. To exit from the user (in this case root) environment to your normal account just type exit or logout.

Really, those should all have
permissions ...

all I did I changed the owner for all files and folders in perl directory to my regular user. I assume it should work in this way.

Errrh. It's going to work for this one user. Should there be
any system tasks that require these they may fail. Bad move.

I recommend you read a chapter or two on Linux file-systems,
ownerships and permissions.

how did you install?

it seems odd that the file permissions are so pants.
the last thing you want is them to be root only.

personally I would just uninstall and reinstall them using your distro
package manager.

Since my PC is dedicated for one task only, there is no any other users to run Perl, which is I would say not bad, but even better move considering security. In addition, I've read all the chapters necessary before I got linux+ certified.

I installed perl through yast, and all other modules from tarballs. Anyway, since changing owner seemed to work, I should be fine because I have only this user in addition to root. Thanks for reply though.

Awesome ... and you understood them, too? :}
I don't mean memorised.

:rolleyes:

No ... :/

Thank you for you all ;) It's good to find a place where people can help :) It's time to read some chapters now ... :study: :D

Actually, it probably isn't a permissions-problem: it is more likely to be the case that Perl cannot find the libraries that you intend to use.

The '@INC' array is where Perl looks. Such things as the PERL5LIB environment-variable, the use lib pragma, and the original list hard-coded into Perl when it was compiled, can all affect that list.
