If you are considering any kind of SAN or NAS check out IPStor software by FalconStor. IPStor can be loaded on two Linux servers. These servers communicate with eachother and will failover automatically. They communicate via fibre channel or SCSI with storage devices (RAID cabinets, tape libraries, etc). They communicate with other servers (NT, Linux, […]

Managing Files With FileRunner
There are many filemanagers available for GNU/Linux; however, the one filemanager that has the most power for managing tons of files is the humble FileRunner. The fancy ones on KDE and Gnome aren’t entirely reliable, mainly, because they aren’t simple. They try and compete with XP by providing icons, previews, etc. That may be cool […]
Adding NFS Users
Add the hostname of the client you want to be able to access your NFS server to /etc/exports. To list the current allowed users: [root@mondo log]# exportfs /share u-1.signalq.com /share srv-3.signalq.com /share srv-44.signalq.com After adding the name to /etc/exports: [root@mondo log]# exportfs -a We added housey, now: [root@mondo log]# exportfs /share u-1.signalq.com /share srv-3.signalq.com /share […]
Point and Print in Samba
If you’re using a samba server to provide print services to Windows clients, why not take it one step further by offering point and print functionality. If you set this up, users *might* even be able to install printers themselves! At the very least it will save you time when you slave over their workstations […]
Default Admin Page for CUPS
Agatha broke her CUPS configuration when upgrading her Gentoo workstation. Simply deleting the old printer and creating a new one works. The thing about CUPS is that it just rocks, and only breaks, to our memory, during an upgrade. The configuration for the daemon is in /etc/cups/cupsd.conf. The cool web-based admin tool makes it really […]
Creating a SAN with iSCSI – Part 1 – Setting up the Target on GNU/Linux
[See This article for a newer procedure.] An iSCSI target is the server piece of an iSCSI SAN. The client piece/driver is called the initiator. We will be running the target on a GNU/Linux box with a 2.4.27 kernel, and will run the initiator on a Windows 2000 server. For our iSCSI target, we will […]
Creating a SAN with iSCSI – Part 2 – Setting up a Windows Initiator – Initial Install
We are going to create a drive that appears to the Windows 2000 operating system as a regular hard disk drive; however, this drive is actually a filesystem on a GNU/Linux box that is exported via TCP/IP using the iSCSI protocol. We created the server to do this in this article. Now, we need to […]
Creating a SAN with iSCSI – Part 3 – Setting up a Windows Initiator – Finish Install
You will see another license agreement box: If you agree, click Agree. You will be notified that the iSCSI initiator is installing: A box regarding the digital signature of the package will pop up: Click Yes if you wish to continue. If the iSCSI initiator installs successfully, you will see this box: A box with […]
Creating a SAN with iSCSI – Part 4 – Setting up a Windows Initiator – iSCSI Setup
You will see a dialog box saying the installation is complete: Click close. Open the Microsoft iSCSI Initiator program. There should be a shortcut on your desktop. If not, it is also in control panel. Open the Add Target Portal tab: The server we want is at 10.50.100.70. Click on the advanced button: The user […]
Creating a SAN with iSCSI – Part 5 – Setting up a Windows Initiator – Creating the Drive
You will see the name of the target in the box: Click Log On to connect to the drive and make it active. You will see a dialog: For now, just leave automatic restore option unchecked. Click OK. Now the available target box has the target listed as connected: Click OK and go into the […]
Creating a SAN with iSCSI – Part 6 – Setting up a Windows Initiator – Finishing Up
Our drive is detected properly now, and we have 3 gigs of unallocated space: Format the disk: If you want the drive to automatically be available at boot, check the box: Let’s copy a file over to our iSCSI drive: This drive is treated just like a hardware drive would be, but it is all […]
Configuring Print Margins With Alignmargins
There is a cool utility available from LinuxPrinting.org that can help align your margins. Below is how we configured our HP Laserjet 1200: [root@srv-1 usr-1]# cd /tmp [root@srv-1 tmp]# wget http://www.linuxprinting.org/download/printing/align.ps –07:04:32– http://www.linuxprinting.org/download/printing/align.ps => `align.ps’ Resolving www.linuxprinting.org… 216.129.135.176 Connecting to www.linuxprinting.org[216.129.135.176]:80… connected.

Quick and Easy NAS using FreeNAS – Part 1
There are 4 parts to this article: Part 1 – Part 2 – Part 3 – Part 4 FreeNAS is a very compact and free (as in BSD) CIFS, NFS, and FTP server with RAID 0, 1, 5 support, and a web administration GUI. Believe it or not the whole install is 16 megs. To […]
Quick and Easy NAS using FreeNAS – Part 2
There are 4 parts to this article: Part 1 – Part 2 – Part 3 – Part 4 Here is the second question that you answer “y” to if you are very confident you don’t have any devices you want the data on hooked up to this system: Now, perhaps you are familiar with the […]
Quick and Easy NAS using FreeNAS – Part 3
There are 4 parts to this article: Part 1 – Part 2 – Part 3 – Part 4 When the system comes back up, it should list the correct interface, as well as the default LAN IP address: Choose option 2 to set the LAN IP address and subnet mask: Reboot again to make sure […]
Quick and Easy NAS using FreeNAS – Part 4
There are 4 parts to this article: Part 1 – Part 2 – Part 3 – Part 4 To test this, we are going to set up CIFS and create a share off of a disk device. First off, we will configure CIFS, and change the workgroup to something different (remote1 in this example). Make […]
Configuring an HP Jetdirect Via Telnet
If you ever need to reconfigure an HP Jetdirect, this can be done via telnet. We have a model 170x; however, this procedure will work with many Jetdirect boxes. First off, you need to figure out the current IP address. Do this by pushing the system test button on the Jetdirect box. The current IP […]
Creating an iSCSI Target with the Linux 2.4 Kernel
This is a very similar article to this; however, we are using the last version of iscsitarget available for the 2.4 kernel. We wanted to bring up a simple iSCSI box quickly to serve as a target for our Mac OS X iSCSI Initiator article. We are working on a generic 2.6 kernal install procedure […]
Mac OS X iSCSI Initiator
There was only one choice we could find for a Mac iSCSI initiator. It is available from ATTO Technology. We used the iSCSI target we set up in this article, which is a GNU/Linux box running a 2.6 Linux kernel. Of course, iSCSI is a standard, so any iSCSI target should work as well. The […]
Creating an iSCSI Target with the Linux 2.6 Kernel
In this article, we set up an iSCSI target for the 2.4 linux kernel. Development for the 2.4 kernel, at least with the iSCSI target we are using has ceased, so we needed move to 2.6. In this article, we will set up an iSCSI target using the latest and greatest iSCSI target software available […]
