Hi, Apologies for the long post - but I'm being driven crazy by this problem. A while ago I built a new server that is intended to serve as a Xen server running multiple DomU systems used a test environments for systems that I am working on. The host Xen system will be CentOS 5 as will some of the DomU systems. The systems will all be hardware virtualized. The motherboard uses the nVidia

Hi Guys, I am trying to set up a quick disaster recovery methodology for a client. It is supposed to work as follows:- All Data files , everything in /etc (except for a few hardware specific files such as fstab), all users .bashrc and .netrc files, all cron tables etc. is written to a DVD as a zipped tar file. A recovery script that unpacks this file, creates any directories required by the

Hi All, I have been Googling my head off but cannot find a method to stream edit all the images in a directory and to resize them. I have a large number of images of up to 3GB in size that I want to put in albums on a website, but before I do this I need to resize them to a more realistic configuration. I know how to do this manually with the GIMP but it becomes tedious for more than a few

Hi All, Last night I downloaded the latest security updates to my Centos 4 system, and rebooted afterwards. This morning I wanted to check my mail, but when I opened Thunderbird, it asked me to set up a mail account. I saved the contents of the previous .thunderbird file structure with tar and created a new mail account with the same details (name, isp, pasword, servers etc.) as the

Hi Some time ago there was a discussion on the above subject. I have scanned the past few month's mailing list archives and cannot find the relevant mail(s). Could somebody please repost the solution or point me at the correct resource. I would also appreciate advice on how to do this on a RHEL4 server being updated with up2date. Is it safe just to delete the old kernel and initrd

Hi, Has anyone on this list had any success with installing and using Open Cobol on RH or CentOS? Any pointers would be very welcome. I have Googled and am working with Vince on the Open Cobol mailing list to try to resolve installation problems. ChrisG

Hi, I am running Centos 4 (fully updated on this box). I removed the old DVD writer (/dev/hdc) and installed a new LG GH20 "Internal Super Multi DVD Rewriter" with a SATA interface - this shows up as /dev/scd0. When I insert a pre-recorded DVD autorun mounts it and displays the contents without any hassles. It appears to me that the required kernel modules are loaded - as copied

Hi, I am trying to set up an automatic connection between CentOS 4 system (server) and a CentOS 5 DomU VM (client) via ssh to enable my to back up development files on the server to the client with a cron process. I generate they key pair without a pass phrase on the client and copy the public key to the same user's .ssh directory on the server as authorized_keys2. When I try to ssh to

Hi, I am running a fully updated CentOS 4 box. Since the last few rounds of updates - upgrading to the latest Firefox, I find that I can not print Bank statements etc ( .ps files when saved to disk). The Bank's logo and any lines on the form print OK but the actual content is distorted beyond recognition - printing a series of special characters (!"$%&#'(") instead of

Hi, I am trying to bring one of my CentOS 5 VMs up to date. I have run: yum clean all yum update yum yum clean all yum update python* rpm* yum clean all without any problems or error messages. Now when I try to run yum update, I get the following: [root at tusker ~]# yum update There was a problem importing one of the Python modules required to run yum. The error leading to this problem

I think scev-aa does not succeed on the original example, because front ends do not put "nsw" on signed addition, so according to llvm rules addition can overflow and i can be < 0. Also, if original example used unsigned type (e.g. size_t, which is very common), I don't think ir can express the fact that i is guaranted to be >= 0. Another line of reasoning is that if

I tried to find anything banning calculating address of one field from address of another in the standard some time ago, but could not find it.
