Angry fc3 /proc/net permission denied


I'm running FC3 and just did an update now my eth0 will not come up. I can cd /proc but not into /proc/net I get "permission denied" even as root. I tested with knopix and all is fine on the hardware. Has any one else seen this? the only other change was the install of VMware, but things kept working after the install of VMware things broke RIGHT after my last update with apt-get. and for the life of me I do not remember all that was updated.

I am not sure if I have the same problem, but...

My Toshiba laptop has been running FC3 for sometime now. When fc4 test came out, I upgraded to it successfully. Everyother day I would run yum -y update.

This command would update my fc4 with the latest packages. Things were fine untill two days ago I did the same then rebooted my machine to enable the latest kernel to reboot.

Now my laptop reboots fine, although the driverloaderbuilder complains about not finding the source code for the kernel to build the system modules!

Then I type my user id and password at the prompt, after the boot is completed. Linux logs me in and tries to create a shell for me, but then it logs me out with /bin/bash no permission.

I checked the permissions on /bin/bash. They are 0755. I checked my ownership of /home/userdir it did not show userdir.userdir it showed 500.500! I am sure that was not the case before.
<br>
What puzzles me is that I can not even login as root, although the /root directory is owned by root.
<br>
I am using redhat8 admin disk to login. When I tried to reset the ownership of my home/userdir of course it did not find me in the passwd file.
<br>
What can I do now to recover my machine? Was I hacked or was it just a silly update mistake?
<br>
Thanks.

no, I have at least 5 older kernels that yum dumped into my hard drive. I was thinking to delete them today, but thought to get some direction first.

I deleted the older kernels.
I forgot to mention, though, that when linux boots I get to Starting udev: MAKEDEV: makedir: File exists
but then it passes.

What has happened?

This is what I get when I try to ssh to the machine from a cygwin machine.

$ ssh root@192.168.15.23
Enter passphrase for key '.ssh/id_rsa'
:
root@192.168.15.23's password:
Last login: Sun May 8 16:18:37 2005
/bin/bash: Permission denied
Connection to 192.168.15.23 closed.

I booted in single user mode. In my /var/log/secure file I found the following:

sshd[3422] error: setfilecon(/dev/pts/0, root: object_r:devpts_t) failed: permission denied

Why is this happening? Am I sending these messages to the wrong thread?

what i can think is that ur kernel is not correct

so get in to rescue mode

chroot to that dir.

and install a kernel rpm frm ur distro CD
