I run Ubuntu 9.04 and was recently told by my university that my computer is massively port scanning the network. I am interesting in learning more about figuring out what is happening to stop it, but I am lost at where to begin. What steps should I take (or files to look at) to figure out what is happening?

Sometimes at startup I get this message "Checking disk 1 of 1". Does that mean it's checking all partitions on the hd? After a bad shutdown there is no prompt for fsck to run and the system just boots up. In fstab I have both options set to "1" for the partition Ubuntu is on, all others set to "0". Any ideas on both?

A site belonging to the Savannah GNU free software archive was attacked recently, leading to a compromise of encrypted passwords and enabling the attackers to access restricted project material.The compromise was the result of a SQL injection attack against the savannah.gnu.org site within the last couple of days and the site is still offline now. A notice on the site says that the group has finished the process of restoring all of the data from a clean backup and bringing up access to some resources, but is still in the middle of adjusting its security settings.
View 4 Replies View RelatedThe infrastructure of the Fedora Project was compromised over the weekend and an account belonging to a Fedora contributor was taken over by an attacker. However, Fedora officials said they don't believe that the attacker was able to push any changes to the Fedora package system or make any actual changes to the infrastructure.
The attack appears to have targeted one specific user account, which had some high-value privileges. The attacker was able to compromise the account externally, and then had the ability to connect remotely to some Fedora systems. The attacker also changed the account's SSH key, Fedora officials said.
I have an OpenSSH server running on Ubuntu 10.04, and it works fine.
I'm concerned that my SSH key may have been compromised and would like to replace it.
I tried replacing keys before and reinstalling OpenSSH and SSH before but ran into terrible trouble so I'm asking for instruction before touching anything this time.
Code:
laeg@skyrocket:~/.ssh$ ls
authorized_keys id_rsa id_rsa.ppk id_rsa.pub known_hosts

So can I just synpaptic 'fully' uninstall SHH (although probably even less necessary than..) and OpenSHH, backup sshd_config, delete the two dirs referenced above, reinstall both packages, insert my sshd_config backup, and then start from scratch following the guides linked below?
I have a server connected to the internet placed in a DMZ that was running ProFTPD. A couple of weeks ago there was a security threat uncovered that would grant access to external users through a buffer overflow. Of course I patched my ProFTPD quite often after that to secure my server. Now my problem is that the servers of ProFTPD were compromised and that source code with a back-door was released. To make matters worse compromised systems notify the hacker they are infected. is there any way to ensure I don't have a root-kit installed short of reinstalling the system?

The free Windows application Speccy returns very useful information about the hardware + software installed on a computer. Before installing Linux as double-boot, I was wondering if there were an up-to-date Linux hardware database so that I could tell users to run Speccy, and then somehow check against that database to make sure their hardware is supported, so that I don't waste time trying to install Linux on unsupported hardware?

View 8 Replies View Relatedchecking of services in Nagios. You all know the check_[service] command right? In the commands.cfg and windows.cfg. To check for the different types of services/ports, we just replace the [service] in check_[service] with the name of the port? I only know of check_http, check_ssh, check_ftp etc. Some ports like Finger, snmp etc, all these we also write it as 'check_finger', 'check_snmp'? 2) And, if that is the case, do we have to install additional plugins to monitor the ports defined earlier? 3) Lastly, if i want to monitor finger,snmp in windows server, would i need to download any software?

View 3 Replies View RelatedI need to know which files were added/modified/moved/deleted after compiling and installing an application from source code, ie. the command-line, Linux equivalent to the venerale InCtrl5.
Is there a utility that does this, or a set of commands that I could run and would show me the changes?
The following is sort of OK, although it includes the lines where changes occured
(eg. "@@ -2,6 +2,7 @@"), and "." and ".." that I don't need: Code: # ls -aR /tmp > b4.txt
# touch /tmp/test.txt
# ls -aR /tmp > after.txt

View 2 Replies View RelatedI have one file called test.sh and in that file I have the below code. All this code is, is paths to three directories (as you can you can clearly see!).
Code:
#!/bin/bash
BACKUP="Documents /bin /sbin"
Now I have this other file which reads the directories (by using $BACKUP) and creates a tar file of everything in that folder. But what I am unsure of what to is create a bit of code that will simply look in test.sh, read all the directories and print a line saying either they all exist or some are missing. If possible it would be good to know which directories are missing too!
I have fiddled around with using -d but I can only get it to work for one directory or manually having to write out each directory.
