Re: [vox-tech] Not able to log into root.
Sorry to reply to my own thread, but in /etc/passwd I do not have root. I didn't remove it though.

Re: [vox-tech] Not able to log into root.
hi rusty, off the top of my head, i would say that your su needs to be setuid root and it's not. you should have a permission of 4755 (rwsr-xr-x) on su. to verify this, i went to google groups: http://groups.google.com/advanced_group_search in with all of the words i typed: su cannot set groups the first item reads: su problem: su: cannot set groups: Operation not permitted i click on it, then click on complete thread. here's the URL: http://groups.google.com/groups?hl=enth=4dec5a92aba3e0rnum=1 it looks like all the responses to this question point to the permission problem. :-) hth, pete begin Rusty Minden [EMAIL PROTECTED] I am not able too loginto root and when I try to su into root I get this error below any ideas? rdm@cc668999-a:~ su Password: su: cannot set groups: Operation not permitted Rusty Minden ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech

Re: [vox-tech] Not able to log into root.
Perhaps a suid-checking script was poorly configured and chmodded the suid bit out? Did you install any security software recently? Coming into the picture recently (SOrry, did not read all of the other posts yet) some questions: Does a normal login from the console as root work? Is the only fault in when you su? The original message makes it sound like you cannot login or su. If that is the case, then there are other things to check beyond just su. -ME -BEGIN GEEK CODE BLOCK- Version: 3.12 GCS/CM$/IT$/LS$/S/O$ !d--(++) !s !a+++(-) C++$() U$(+$) P+$+++ L+++$(++) E W+++$(+) N+ o K w+$+ O-@ M+$ V-$- !PS !PE Y+ !PGP t@-(++) 5+@ X@ R- tv- b++ DI+++ D+ G--@ e+++ h(++)+ r*? z? --END GEEK CODE BLOCK-- decode: http://www.ebb.org/ungeek/ about: http://www.geekcode.com/geek.html On Tue, 23 Apr 2002, Shawn P.

Re: [vox-tech] Not able to log into root.
hi shawn, i had the same thought myself, but didn't post it. now that you bring it up... rusty, something happened between the last time you were able to su and the time at which su stopped working. rusty, is this a woody system? if so, su belongs to the package login. the current version of login is 2902-12 (you can get this by 'dpkg -p login'). if your OS and package version number match this, check your md5sum. here's mine: 5d324ad212b2ff8f767637ac1a8071ec /bin/su pete begin Shawn P.
