Im trying to find out What all network hardware is required for a successfull Iscsi setup. Example Do you need two network cards that support it. Or do you just need one network Iscsi adapter for the storage box, and the other machine just have a normal NIC. What type of Switch would be needed as well for decent transfer rates.

Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?

I have never done this before but stood up a new Debian (testing) x64 system. It only has 146GB available for RAID1 so I created a 500GB iSCSI LUN on my NAS device on the network and am really confused how I can attach my Debian to the iSCSI LUN I created. Right now the OS is installed all locally on the machine but I would like the iSCSI LUN to be the /home directory for mail storage. Is this possible or do I need to mount the LUN to a newly created folder / mount point that is locally attached?

I am interested in turning my home server into something that I can store backups on. I do photography and therefore have a lot of photos. I use Mac OS X for my photo editing, so it must be accessible from my Macbook. I am new when it comes network storage servers, so what would be the best solution for me to be able to backup my photos seamlessly? I would like it easy enough so others can backup files without any terminal commands and such. What would you suggest? CIFS? RAID? iSCSI?

I have a unique setup on my hands..-local (LAN) dev system built on a via epia m6000 (uses the older via eden-samuel cpu). Latest kernels will not boot due to cpu issue.I'm running CentOS v3.9 for kernel compatibility and have managed to get my basic LAMP setup accomplished via yum but I'd like to run the curnet versions of everything while keeping the older kernel if possible.I'm considering setting up my yum repos to include v4 or v5 and use the yum --exclude kernel option.

View 1 Replies View RelatedI am trying to set up a SSH key between servers so no password is required when I have to "scp" files between the two. This is what I have tried so far but still requires a password:
Code:
ssh-keygen -t rsa
scp /home/<user>/.ssh/id_rsa <server2.com>:/home/<user>/.ssh/athorized_keys
When I scp after this I wasn't expecting to need a password but it is still prompting. Now I have used this same method before and it has worked great. The only difference this time is server2 is not in the same cage.
If I do System-Preferences-Personal File Sharing it tells me that I can't enable sharing over the network because "the required packages are not installed on your system". It doesn't tell me WHAT packages I need to install!

I've been learning linux for a while now with half an eye on making a career out of it in future. One sizeable gap in my knowledge at the moment is networking. Is it feasible/desirable to set up a network of virtual machines to use as an environment to learn networking? My budget is non-existent so I was hoping to be able to get a basic understanding of the principles from installing a few desktops, a virtual gateway etc on VMware workstation on my laptop, and doing a lot of reading online.
Is this feasible, or will I just end up learning about virtual networks instead of real ones? Also how much power would be required, because my 3GB RAM lappy has just gone bang and all I have now is a (new) 1GB RAM lappy.
I'm trying to set up a network in the manner shown in the attached schematic. My problem is the ones hightlighted in purple, everything else is working fine. Could someone give me a quick tips on how this can be done (if at all possible)?The computer the router is connected to will be running linux (ofcourse).
What mode should i set the router to? I've listed the available modes below.Is there any way i can prevent the game consoles (or computers) from being able to contact anything but internet past the router or bridge computer? i.e the bridge computer becomes the only visible gateway?I'd prefer them to have their own ip range behind the bridge computer/router and use the DHCP function in the router, or perhaps setup DHCP on the bridge computer.I would like to be able to view the traffic going trough the bridge computer.What gateway and dns ip setup should i use on the router and the consoles/computers connected to the router?
At my workplace, Ubuntu connects to the wireless internet with no problem at all. When I log into openSUSE or PClinuxOS (the other two distros I use) I can't connect.

View 3 Replies View RelatedNewbie Question: How do I setup networking on openSuSE 11.4 on an HP Proliant DL385 G7 with 4 NICs to host Windows 2008 R2 on Xen? I've installed openSuSE 11.4 with all the patches (and most of the server patterns - Mail and News, LAMP, LDAP, Samba, etc.), and I've installed Windows 2008 R2 in a Xen virtual machine. I'm having problems configuring the 4 NICs eth0, eth1, eth2, eth3 are "bound" without an ip_address as br0
eth0 connects to my ISP - currently through a private LAN - It connects directly to the router with static IP 192.168.0.105 Eventually, one of the other NICs will serve ip_addresses via DHCP to a separate LAN (for use in an office setting), and eth0 will be set with a static IP from the ISP That means, eth0 will be static to the ISP, and the other NICs will attach to a switch serving private ip_addresses in the 192.168.0.xxx range.
Currently, I have br0 unconfigured and eth0 static. I have configured eth0 in the External Zone and br0 in the Internal Zone in the firewall, and all the correct ports are opened (afaik) I have enabled masquerading. Hostname, Domain (workgroup), DNS Server addresses and IPv4 Gateway are configured.
Windows 2008 R2 (Guest VM in Xen) "sees" the other machines on the network, and "browses" the internet, although it will not download patches except intermittently. I have not tried connecting to it from the LAN Eventually, I wish to run Windows Terminal Server. openSuSE cannot "browse" the internet, though it initially did. What am I missing? I "think" I need routing or NAT, or I may have my bridge setup incorrectly, although I've tried almost every combination. Google says Xen should be setup with either NAT or a Bridged Network.
Output of ifconfig:
br0 Link encap:Ethernet HWaddr 3C:4A:92:76:B8:F2
