DCOPserver/permission issues (still)

Thanotos · 11-20-2005, 11:32 PM

The saga continues....

On 11-11-2005 @ 03:19 PM I asked a question regarding an error when using users other than root fail to load with KDE. ~I recieved no responses

~

After countless attempts of trying to figure out:

Quote:

There was an error settuping up inter-process communications for KDE.
The message returned by the system was:

Could not read Network Connection List.
//: .DCOPserver_stealth__0

Please check that DCOPserver program is running.

{press the 'OK' button}

{new error pops up}

Quote:

Will not save configuration

configuration file "//.kde/share/config/kwinrc" not writable

configuration file "//.kde/share/config/kdeglobals" not writable

{press the 'OK' button}

... and working on the idea that it was a permission issue. I was humbled (again). I thought - 'k', I was good at "FUBAR", lets remove the users not working and add new ones. After all - if they don't work why keep them and with new users logic should agree that the errors would cease.

Unfortunately that idea failed as well.

I am still getting the same errors as the above

If there is anyone that has any suggestions, I am open to try anything. My fear now is that my /home is corrupted. The good news is that I do have /home on a seperate partition, I am just not sure how to repair or 're-install' if necessary.

Does anyone know if I could delete the KDE files and if they would re-write/create them selves. (probably not I am thinking - am new to this after all).

I have tried the command:

Code:

 rm -rf ~/.kde

(all that seemed to do was allow me to restart KDE for the / user.

And I am sure that it is related, I am still getting permission errors with all users other than /.

For example:

Code:

root@stealth:~# su thanotos
bash: /home/thanotos/.bashrc: Permission denied
thanotos@stealth:/root$ rm -rf ~/.kde
rm: cannot remove `/home/thanotos/.kde': Permission denied

Try entering this in console / bash

Code:

cd ~
su 
(Enter your Password)
chown -R thanatos.users /home/thanotos/

& See if it helps

How did you get into /root as a normal user?

Sounds like the permissions on your machine are completely wrong.

Code:

The permissions of your directories should look something like the above (subsituting your own name of course).

Root is the only user that I can log into. All other attempts with other users gets the described error.

Thanotos · 11-21-2005, 07:15 PM

oops forgot to add to slaxnoob's suggestion:

entered in the code as specified within / bash and then checked right away and here is the result:

Code:

root@stealth:/# chown -R thanotos.users /home/thanotos/
root@stealth:/# su thanotos
bash: /home/thanotos/.bashrc: Permission denied
thanotos@stealth:/$ whoami
thanotos
thanotos@stealth:/$ cd /home
bash: cd: /home: Permission denied
thanotos@stealth:/$

keefaz · 11-21-2005, 07:19 PM

what is the output with :

Code:

id thanotos
ls -ld /home
ls -ld /home/thanotos

?

keefaz · 11-21-2005, 07:24 PM

I didn't pay attention to your previous outputs...

try as root :

Code:

chmod 0755 /home

(for some reason the executable bit to your /home dir was removed but
this bit is needed to access a directory...)

Thanotos · 11-22-2005, 06:22 AM

Thank you everyone,

Keefaz your suggestion appears to have worked. If I could possibly be one more pain in the rear and get a speculation as to what happened and why changing the permissions worked?

Alien Bob · 11-22-2005, 06:54 AM

Someone or some process changed the owner of /home to a user ID of 777 and removed the executable bit from that directory.
I would advise you too look into /etc/passwd to get a clue about what user account that could be.

Eric

keefaz · 11-22-2005, 07:04 AM

I didn't notice that

Thanotos>you need to reset /home perms with : chown root:root /home

I guess it was owned to 777 uid because you did make a confusion between
chmod and chown, you did chown 777 /home to set the read write execute
bits, but chown change owner of the file so /home was owned by 777 uid
after the change (/home has to be owned by root user and root group)

That's a logical explanation.

Hey Thanatos, why are some of your users in the 'root' group?

They should be in the group called 'users', because using the 'root'
group can be dangerous. It could be part of the reason you've had
the problem with directory permissions.
