Need help. Got virus and now stuck at start up.


Will is seem I got a virus from a networked hard drive.
My linux box is now stuck in the stratup mode.
The virus was Win32pa. I have unplugged my network cable and am in the middle of virus scan one win98. Once its completed I start on win98 on the other machine.
But for right now here is my problem.
Linux RH8.0 is stuck in the start up mode asking me the following:

It wants me to run fsck

Here is what is says on the screen:

Checking root filesystem
/contains a file system with errors, check forced
/:
inode 16737 has imagic flag set.

/:UNEXPECTED CONSISTENCY; RUN fsck MANUALLY
( i.e. without -a or -p)
*****An error occurred during the file system check
**** Drop you to a shell: the stem will reboot.
**** when you leave the shell
Give root password for maintance
(or type Control-D for normal startup):


At this time I entered my root pass word.
It replied with :

(Repair file system ) #1


What is it asking me to type in ? I know it starts with

fsck ( but what comes next????)

It's dropping you to a maint shell. Try

fsck /dev/hda

That is assuming that your main HD is ide. Replace the hda with whatever device is your primary hd that your root partition is based on.

This problem sometimes occur when your linux box isn't shut down properly.
The fsck utility is the equivalent of scandisk in windows.
Normally this program is able to run without intervention by the user, but sometimes like in this case it can't be absolutely certain what to do.

You will get a few questions along the way when running fsck. Almost all the time the standard reply will do. This manual check is a safety precaution from the system to make sure how to do.

get a copy of tomsrtbt or mulinux and use it to fsck your linux partion with "fsck -Asa /dev/hdxx" where xx is the harddeive and the partion of your linux file system
IF you have win2000 or XP use mulinux insted there is a bug in windblows that messes up the system when floppys larger than 1.44M are read
I say use tomsrtbt or mulinux because there is some kind of problem that fsck needs to have the file system unmounted to fix and can't do it with the filesystem mounted read olny or it would have fixed it at boot up

Thanks to everyone I was able to do the fsck and get back in.
I was not sure about some of the questions it asked me but I quessed right.

Additional question can a windows virus cause problems thru a network connection like I have?

1 linksys 5 way hub
1 win98 box
1 linux box

I some how got Win32 OPAS. I have AVAST running on the win98 box.
This is the second time I have gotten this virus in the last month. I have a feeling it is on something I am using. Anyhow can it mess up linux to?

Because I had the 2 boxes running and everything was ok then everything stopped. Both win98 and linux, when I rebooted the win98 box informed me that I have the virus. I promply had it take care of it. However when I went to boot the linux box this is when I got the above problem.
Was this just coincedces or did it mess with the linux box?

Any way thanks for the help again.

Windows viruses are harmless to linux. Once the virus hits the linux box it is dead - it can't even run to email itself to other users (the only way it could spread is if you intentionally email it to windows users).

The only way a windows virus can harm a linux box is if you have a dual boot system win/linux, then it can mess up your harddisk.

Unfortunately, the only way you can be sure that you will not be affected by Windows virri is to not run Windows. As Ugge mentioned above, the only possible way that your Linux partitions were affected is that the virus fiddles with your harddrive. To me this seems unlikely, but not impossible. You could always ensure that you only connect to any kind of network when running Linux... effectively remove any means of entry for Windows virii. Or just remove Windows

boot sector viruses are still out there even if you don't run windows you can still get a boot sector virus by booting from an infected dos boot disk (most likely some one else booting your computer from such a disk trying to get around your pass word)

I would also suggest using ext3 file system. This is less sensitive to sudden shutdowns which make recovery very easy. Do tune2fs -j /dev/hdxy .

i was getting a similar error about "a file system with errors, check forced" and getting booted into "maintenance mode" during an openSUSE 10.3 install today. just running fsck at the command line with no other parameters got me past it. thanks!

Clue 'ya... it wasn't "a virus."

It was a corrupted filesystem (or what might have been one ... one must err on the side of caution...). Nothing more.

I agree with the corrupt file system. But isn't it possible a virus could be executed through wine? Most likely the virus would need to be manually executed, either intentional or not. At this stage, it could conceivably freeze the computer (wine has frozen my computer a few times), forcing the OP to reset, and cause the file system to corrupt.

Am I right, or am I right?
