 |
|
Argh I am having all sorts of permission issues trying to get a user to log in through GDM.
Firstly /dev/null problems, whenever i startup up the PC /dev/null is always set to these permissions
| Code: | chris-linux chris # ls -al /dev/null
crw-rw---- 1 root root 1, 3 Jan 20 00:08 /dev/null |
Yes i can change the permissions but they never stay after a reboot! What am I doing wrong?
Secondly my user can't su despite being in the wheel group.
| Code: | chris-linux chris # id chris
uid=500(chris) gid=100(users) groups=100(users),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),17(console),18(audio),19(cdrom),27(video),32(gdm),80(cdrw),85(usb),250(portage) |
I simply get an authentication error - again am I missing something simple here?
| Code: | chris@chris-linux ~ $ su
Password:
su: Authentication failure
Sorry. |

OK I have made some progress on this by searching on the contents of .xsession-errors
If I chmod /dev/null and /dev/urandom to 666 i can now login, though i still cant actually start any programs (bizarrely)! I've read these problems are related to udev but not can a proper answer yet!
The search contuinues...
[edit] Further progress has been made:
| Code: | emerge --unmerge udev
rm -r /etc/udev
emerge udev |
Solved the terminal issues, however still not solved the SU problem!
[/edit]
[edit2]
Solved the SU problem, seems that /bin/su had the wrong permissions. AFAIK it chould be set as follows:
