Hi all, Which ports do I need to have open on an NFS client's firewall to allow it to connect to a remote NFS servers? When I disable iptables (using ConfigServerFirewall), it connects fine, but as soon as I enable it, NFS gives me this error: root at saturn:[~]$ mount master1.mydomain.co.za:/saturn /bck mount: mount to NFS server 'master1.mydomain.co.za' failed: RPC Error: Unable to

Hi all, Has anyone managed to get CentOS 6 domU (i.e. guest) working on a Debian 6 do0? Both OS''s are 32bit and I''m running XEN 4.0.1 with HVM support. A CentOS 5.6 domU works fine on this very same server though. When I start CentOS 6, I get the following error: newusaxen:~# xm create -c /xen/genocide.cfg Using config file "/xen/genocide.cfg". xenconsole: Could

Hi all, Has anyone seen something like this before: I want to use a laptop as a KVM console. Basically when a technician goes to one of our datacentres, or clients he has to look for a free LCD, keyboard & mouse to connect to a server (no network access, reinstall, troubleshoot failed kernel / HDD, etc). And then hopefully there's an open power socker in that cabinet. So I'm

Hi all, Does anyone know what the correct steps are to add a XEN bridge, let''s say xenbr0 to Debian Squeeze? I have added the following to /etc/network/interfaces # XEN Bridge auto xenbr0 iface xenbr0 inet manual bridge ports eth0 bridge_stp off bridge_fd 0 And then rebooted the server but brctl show still shows eth0 as bridge: newusaxen:~# brctl

Hi, I'm looking for a firewall (preferably on Linux / UNIX) that could automatically block bandwidth abusers as soon as a connection goes over a certain speed, or limit - i.e. either more than say 3Mb/s or 10GB in a giving period (like weekly / monthly). But, I need it to block the IP to, or where the traffic comes from, or goes to. i.e. a user logs into a web server and upload a LOT of

Sorry about the previous post, I see the subject had a typo. So here's the correct one :) Does anyone know how to configure Postfix to use SMTP authentication on a relay host? i.e. I have a Linux server, running PostFix on an ADSL line with a dynamic IP. Thus I can't just send out emails from this server but need to relay it via our ISP's SMTP server, which is very unreliable. Now

If you use any NAS (or a SAN) devices, what do you use? And I''m referring more to larger scale network storage than your home PC or home theater system. We''ve had very good experiences with our NetGear ReadyNAS devices but I''m in the market for something new. The NetGear''s aren''t the cheapest ones around but they do what it says on the box. My only

Hi, What is the preferred OS to use with XEN, as the dom0 host? We primarely us CentOS (currently 5.6) but it seems that the native XEN that comes with CentOS is a bit behind.

Hi, I have a problematic CentOS XEN server and hope someone could point me in the right direction to optimize it a bit. The server runs on a Core2Quad 9300, with 8GB RAM (max motherboard can take, 1U chassis) on an Intel motherboard with a 1TB SATA HDD. dom0 is set to 512MB limit with a few small XEM VM''s running: root@zaxen01:[~]$ xm list Name ID

Hi all I have a CentOS 5.1 x64 server, running Xen version 3.1.0-53.1.21.el5 & Windows 2003 VM. After doing a software update in Windows (via Remote Desktop), I rebooted windows, but it never came back up. So, I logged into the server via SSH, and destoyed the VM, and recrated it. Yet it doesn''t boot up ( I can''t connect to it via RDP). So, how do I debug it to see

Hi all, I need to setup a real bare minimum CentOS Virtual Machine, but with normal internet / network access. i.e. I need SSH, Mutt, Links, lynx, ping, tracert, dig, iptables, etc. Does anyone know where (if?) I can get a list of applications which gets installed with CentOS 6 if every option is deselected in the installer so that I can see what I can remove which isn't really necessary

Hi, Can someone please assist met with some software RAID 1+0 setup instructions? I have searched the web, but couldn't find any.

Hi all, I hope someone can help me with this please. One of our clients has an in-house Postfix mailserver which basically downloads mail for the individual users from our mail server hosted on the web using fetchmail. They use our SMTP server to send mail. Their email clients are then setup to get & send mail from the server, on 192.168.2.254 (for POP3 & SMTP). All mail between them

Hi, Has anyone been succesful in installing oVirt on CentOS 5.3? While it looks like a greate virtualization package, they only support FC10, and the installation instructions are for FC9. So, has anyone installed it on CentOS yet? If so, would you mind sharing with me whether it was a problematic installation, or not really? -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web:

Hi all, I'm sorry if this is a quick dumb one, but how does one install ip6tables?

Hi, Does anyone know of a stable / working "2way authentication" system for SSH, and even web authentication services? Most of the banks in South Africa have a system that, when you want to make a payment, they send you an SMS and you need to verify the action with a secret code which was SMS'd to you. gmail also has this. Does anyone know of a "universal" plugin /

Hi all, Does anyone know how to control a hard drive light from Linux? I'm building a 24bay Linux File server which will run software RAID and I need an easy way for the engineers to see which HDD has gone bad. Most of our NAS devices has 2 lights on the hard drive cages and they automatically signal a bad one (reg light, light constant on , etc) but I can't figure out how todo this from
