Re: su command not found.

Hi Bruno,

this command should be in /bin
check PATH valriable and whether /bin/su exists.

Re: su command not found.

Hey Michael,

I´ve checked the /bin directory and there is no "su" there ... Why ?

I also checked the PATH variable and it´s apparently OKAY.

Any other clues ?

Thanks

Re: su command not found.

Hi,

looks like someone deleted it. Restore from backup or from another machine with the same os release.

find / -name su -print
Any place else perhaps?

Re: su command not found.

Hi,

if you are lucky you find it in the shell history of the root user, but that's pure luck.

Re: su command not found.

Hey guys ,

I restore the command and it worked fine.
I got the person resposible for making the "su" command disappear.
There is another person that access the server from a different state and he also does some administration tasks.
He renamed the su command to zz ..
He said our boss told him to do that , i called up the boss and explain him the situation. THey were worried about security , using the "su" command to loggin as a different user and enter on the ERP system to mess up something.
But i explain that the only personsthat has full access are I and the other guy that dissapearwith the "su" command.

But anyway,

Thanks a lot guys , i am really learning many stuff in this forum.

Regards

Bruno
