Hi, I am using Centos 5.4 x86_64 with kernel 2.6.18-164.11.1.el5xen. I've installed a Centos 5.4 (64 bit too) DomU (paravirtualized), process was apparently with no problems, but DomU refuses to start, this the error: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 498, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 573, in startup self.vm.create() File "/usr/lib64/python2.4/site-packages/libvirt.py", line 287, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: La operación POST falló: xend_post: error del demonio de xen: (xend.err "Error creating domain: Boot loader didn't return any data!")

There is two disadwantages with it: first, it's quite untrivial task to get it working under Centos, and second, it doesn't work anymore :) >From official fuse-gmailfs site (richard.jones.name): Gmail Filesystem no longer works with the latest Gmail interface, and will not be maintained in the future. BTW, according to google EULA, it's illegal to use gmail it that way. Gmail team could even disable you account. I would suggest you to take a look at dropbox, which provides 2-5Gb online storage with full desktop integration on lin/win/mac. At the moment it's quite tricky to install in under CentOS, because it uses python 2.5 (CentOS has python 2.4), but it's achievable: http://wiki.dropbox.com/TipsAndTricks/CnetOS-KDE-Install . Fancy GUI isn't working at the moment. I'm currently backporting it to CentOS, and I would like to include it in rpmforge (it's distributable). I estimate it in about one week. I hope it'll be useful ... Nikita

Question about running a CentOS4.8 (32-bit) guest under CentOS5.4xen (64-bit)

I am trying to run my old CentOS4.8 (32-bit) system as a guest system under CentOS5.4xen (64-bit).

Git: help sought
by Timothy Murphy 23 Jan '10

23 Jan '10

I have a project using Git on machine A. I'm running a Centos server on machine B. I'd like to "publish" the project on machine B (mainly for my own use, so I can access it from various sites). I've asked about this on a Git mailing list, but haven't understood the replies. In particular, a couple of people suggested gitolite, but when I examined this I couldn't make out what it did. As will be obvious I am a Git newbie, having been reared on SVN. But I thought some CentOS users might have met this problem and come to a simple solution. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

Centos security sshv1
by Alejandro Rodriguez Luna 22 Jan '10

22 Jan '10

Hi all! I was scanning my servers with nmap, ( i have installed ssh), and the result gave me this: 22/tcp open ssh sshv1: Server Supports SSHv1 ssh-keyhost: 1024 ea:7e:77:b7:a1:78:18:70:6c:46:ee:a0:dd:08:0e:74 (RSA1) 1024 ba:d0:8a:44:16:fc:7c:7a:38:24:2e:72:06:fe:99:56 (DSA) 1024 ff:43:15:78:98:3c:75:f9:12:36:58:92:46:6c:1c:99 (RSA) could this be a threat for intruders? i know that sshv1 should be avoided, but all i want to know is if with that information, a intruder could compromise my server?

OT: free DNS service?
by Lanny Marcus 22 Jan '10

22 Jan '10

I have been using a free DNS service for the past seven (7) years. This morning, at 4 A.M., , I changed the "A" record for one of my web sites, to point to an IP address on a different server, so I could test. After watching the TTL count down from 3600 to zero, with the "dig" command, it then reset to 3600, but still resolved to the original IP address. :-) I set the "A" record back to the original IP address and filed a Support Ticket with that company, but if they cannot get this to work properly again, I need a new DNS service that is free. Recommendations? (BTW, the Domain is registered with GoDaddy, but not hosted there, so it appears I cannot use their "Total DNS" service). TIA!
