There is this great software for doing remote unattended Windows installs called, well, Unattended. It allows you to boot/install different windows versions without any intervention which is great if you are doing a number of Windows installs. This is a bit different than MSFN’s Unattended install which mainly is done off of CD media. MSFN’s site is still a great source of information on these types of installs but we are focusing on the network Unattended software since we are too lazy to have to/want to physically be at the datacenter to do the installs! If the windows included drivers.cab does not include your drivers, then once unattended (I’ll refer to the sourceforge network version of unattended from now on) installs windows, you will not be able to use the network card to access the PC any more. Therefore, you need a way to install 3rd party drivers directly into….

Not dead as in dead, but dead as in the user has logged out of the system and for some reason their shell is still open. This might happen if your system crashes before you can log out, there are network problems and you are disconnected, or a number of other reasons. This article explains how to log these “dead” shell users out.

If you are a system administrator of a linux system, you may find the following log entries familiar: 12345Sep 15 02:00:30 sol sshd[16364]: Failed password for invalid user test from ::ffff: 61.167.x.x port 53382 ssh2 Sep 15 02:00:30 sol sshd[16365]: Failed password for invalid user test from ::ffff: 61.167.x.x port 53394 ssh2 Sep 15 02:00:30 sol sshd[16366]: Failed password for invalid user test from ::ffff:61.167.x.x port 53396 ssh2 Sep 15 02:00:28 sol sshd[16366]: Invalid user test from ::ffff: 61.167.x.x Sep 15 02:00:28 sol sshd[16370]: Invalid user test from ::ffff:61.167.x.x Many, many times over. These are caused by an brute force attack from the remote host. Most likely this is another compromised machine, checking your machine for easy to guess username and password combinations. It could be someone manually trying to run a password cracking program on your ssh server too. In either case, the remote system really has no business….

If you need to find a string in a file, you would typically use: 1grep -H "string to find" filename.ext However, grep doesn’t handle a large number of files well. If you specify 1grep "string" * or even 1<em>grep "string" `find ./`</em> you may find yourself facing this error: 1bash: /bin/grep: Argument list too long If you need to search for a string in a lot of files then you can use a simple bash script to do the searching for you. In this sample, I am looking for a string “sample string” in a directory named “./sample/”: 1for i in `find ./sample/`; do grep -H "sample string" $i; done This uses the find command to do the searching. It actually returns a list of filenames, which we can then grep one-by-one. The -H option tells grep to let us know the filename it found the string in so we….

Here is a handy little shortcut I recently figured out (it took me long enough, didn’t it!). You can mount an ISO image as a directory in linux. Very nice for when you are remote and want to have a CD on that system. 1mount -t iso9660 -o loop imagename.iso /mnt/isoimage
