Parallels is selling virtualization products and web hosting solutions. I was originally using a hosting package called Ensim, but Parallels bought Ensim over a while ago. Today, due to business growth, I need to expand my hosting capacity and to add an extra licence from Parakllels. > > As far as my other systems are concerned, (pen testing) I will reinstall > > them under Centos 5.2 in the coming weeks > > you dont need to reinstall to get from 5.0 to 5.2, if you do a yum > update, that will bring in all the updated packages. ( remember > 5.0+updates == 5.2 ). I currently run Fedora 7 --> I have to rebuild brand new systems from ISOs Thanks !

Simple IPTABLES Question
by Matt 22 Aug '08

22 Aug '08

I added these rules to IPTABLES to slow brute force attacks. iptables -A INPUT -p tcp --dport 22 -s my_subnet/24 -j ACCEPT iptables -A INPUT -p tcp --dport 22 -m state --state NEW -m recent --set --name SSH iptables -A INPUT -p tcp --dport 22 -m state --state NEW -m recent --update --seconds 60 --hitcount 5 --rttl --name SSH -j DROP I would like log entries when connections are dropped to see that its working. How do I do that? I am guessing I would add this before the drop. iptables -A INPUT -p tcp --dport 22 -m state --state NEW -m recent --update --seconds 60 --hitcount 5 --rttl --name SSH -j LOG --log-prefix 'SSH attack: ' Is that right? Thanks. Matt

iscsi and the last mile...
by Scott R. Ehrlich 22 Aug '08

22 Aug '08

I have a new Dell PowerEdge 2950 running CentOS 5.0 out-of-box and a Dell MD3000i. I am new to iscsi and, with google and included documentation, am having a heck of a time trying to get the RAID volumes I have created on the 3000i to be seen by the OS as usuable drives. I have printed out SMcli and iscsiadm documentation. I have asked on the linux-poweredge(a)dell.com site, too. Many leads, but there is something - be it a command, setting, or whatever else, that is just eluding me. How do I get the RAID devices seen on my C 5.0 box? The setup is currently on an isolated LAN and has no valuable data - all testing and experimenting by me, for now, to learn how it works, before putting it into production. Thanks for any and all leads. Scott

Xen "bridged" networking config
by David Dyer-Bennet 22 Aug '08

22 Aug '08

I've got a Centos guest and a Windows 2003 server guest running in Xen under Centos (5.2 in both cases), and they can get out to the network, and I can ping them from dom0. This is my first Xen install, and I haven't used Linux as a router before (I'm very familiar with it as a webserver and development platform) so I'm a bit weak on the bridging code and NAT / IP masquerading. (Amusingly, I was a voting member of IEEE 802.1 and worked on the .d standard for bridging; that was back when it was new, more than a decade ago, and my memories from then may be doing more harm than good now.) The problem is, I can't originate a connection to either guest from outside. Dom0 is getting IP 192.168.1.91 (from our enterprise DHCP server), which is a reasonable address. There are two bridges created, xenbr0 and virbr0. Virbr0 has an IP of 192.168.122.1 assigned to it, which evidence suggests did *not* come from our DHCP server. The interfaces for the two guest domains have 192.168.122.185 and .198 assigned, also not from our DHCP server. The IPs plus the behavior (can't connect in, can connect out) make it look very much like NAT has been setup, but I can't find any evidence like a "MASQUERADE" target in the dom0 iptables or anything (I've never run NAT on Linux, I could be looking for the wrong thing in the wrong place). This setup does not look anything like the "default" bridging config I find documented on various Xen websites (particularly <http://wiki.xensource.com/xenwiki/XenNetworking>). None of them have "virbr0". I've seen a number of reports that people's working configurations broke when the upgraded to Centos 5.2, so I'm suspecting that what I'm seeing here is how Centos 5.2 chooses to package Xen. And hence I'm asking on a Centos list :-). I created these guests in virt-manager. I selected the "bridging" network configuration. Oh, ip forwarding is on in dom0; that was one of the things several places I looked said was an obvious fix for my problem, but it was already on in the default config, and it wasn't helping. I'm currently not using either vlan or bonding, though I believe both are in my future. One thing at a time; and if I understand the basics I think I just might be able to take it to the next stage. This has gotta be simple; I want the most basic bridged configuration, with the guests directly visible to the outside world. Any ideas? -- David Dyer-Bennet, dd-b(a)dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info

kickstart error on 5.2 exception
by Jerry Geis 22 Aug '08

22 Aug '08

Hi, I am trying to get my kickstart file that worked under 5.1 to work under 5.2 centos x86_64. This is the error that I get. On the screen it says Exception occured and gives me the option to save it. This is that file. I dont see any odd that would cause it to crash. Can anyone help. My kickstart file is in the mix below. Seems to be related to network, my line seems fine (I think) for network.

I am trying to help a friend with a 2850 and snmp monitoring of a controller and its arrays. I don't have any dells, do they have a rpm to make easy work of this for the Percs? They have a monitoring solution already. Any hints I could pass on would be appreciated! Thanks, jlc
