I was trying to generate ssh key for my server and get this message below
Code:
[andyj@server ~]$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/andyj/.ssh/id_dsa): [Enter]
Enter passphrase (empty for no passphrase): [Enter]
Enter same passphrase again: [Enter]
open /home/andyj/.ssh/id_dsa failed: Permission denied.
Saving the key failed: /home/andyj/.ssh/id_dsa.
andyj: this is my username for my domain which is hosted in that server.
How do i allow 'andyj' user to have permission to do this? Note, I can do this with 'root' just fine. I'm using CentOS 5.
Just wondering if you guys had any resolutions to this. We are looking to save space on our rsync backups.
I know you can use the --compress, or -z and it compresses data on the fly to save bandwidth but is there anyway to keep the data compressed so it takes up less space once it is on the server and still make it so it only copies over the file changes?
If not, anyone have any suggestions on how to save space with rsync backups?
Is there a way to use a Web browser to open a file at [url], make changes to the file and save it back on the Web site? I am trying to do this but have only been able to save the file locally. The file only opens in [Read Only] (Compatibility Mode).
Just colocated at HE.NET and the the 15 amp limitation is a challenge. I'm just wondering what tricks there are to reduce power consumption by computer. Maybe people can add their tricks to this thread.
I'm experimenting at home right now. I got one of those KILL-A-WATT meters. (Egghead $18 - they are GREAT) And I'm measuring power usage with different configurations.
One thing I noticed is that the bios "cool and quiet" setting make a big difference. At idle current drops from 0.90 amps to 0.67. Of course if the processor is running 100% this probably goes away but if you have a cabinet of server and not all of them are maxed out all the time this should add up.
I'm using OpenVZ virtualization which allows my to use hardware more efficiently.
Just wondering if any of you have other tricks that cut electrical usage. Might have to put quad core processors in all my servers for expansion. Wish AMD would get their act together and get high speed quads out there.
I have Cpanel VPS account, and have been regularly backing up all my outgoing emails (via SMTP, imap or webmail) with the following:
Added to following lines in /etc/antivirus.exim
Code: if first_delivery and ("$h_from:" contains "username@domain.com") then unseen deliver "backup@anotherdomain.com" endif So, this worked well for the longest time. At some point it 'disappeared' and stopped working which I guess was due to some update, and putting it back it got it working again.
Recently, I had a new vps, moved my domain there and dropped the same bit in, but this time around, it didn't work.
Is it possible that antivirus.exim isn't being parsed? How do I check? Or is there somewhere else I can stick it into so it'll always work and not get replaced by some cpanel update?
I want to change SOA Settings from defaults to these: When I press OK button shows that is saved but when I test with [URL] .... and [URL] .... shows that settings still is defaults.How to change these settings??
We have a Windows 2003 Enterprise server with 6GB of RAM and about 20 terminal services users logging in. These users then launch a program called Accuthin Thin Client giving them access to a piece of software called Southware that runs on a Centos 5 Linux server on the same network.
Problem seems to be that saving files to the network share causes windows to blue screen and crash. Has anyone ever heard of this before? I know it is a shot in the dark but we have been investigating this issue for 4 months, have replaced the Windows server 5 times, increased RAM to 8 GB and installed Enterprise edition clean but the issue follow no matter what we do.
I did a Graceful Server Reboot, but it seems httpd service not running yet,
I got this error after try to restart Apache..

I am receiving a lot of cpsrvd emails every day and I am unsure how to stop this error.
I have read somewhere that a possible cause is that there is no space left on the server. I do have a warning in my WHM next to "Disk /dev/hda6 (/) DMA+ 86 %". Could this be a possible cause of the problem?
Code:

I have httpd down right now without any error outputted on errors_log my server is with 4 Quad-Core Intel Xeon 2.66GHz (16 CPu) and 16GB of RAM. Is running CentOS Linux 5.1 and Apache/2.2.8.

my apache crashed and I trying to restart apache from SSH, when I run "service httpd start" I didn't get any message and I come back yo command prompt, but the httpd is down yet
Our DC was perfoming a hardware test on one of our servers and two hours later, they have said:
A fsck was run on this machine which seems to of failed somehow, resulting in the machine failing to boot under any kernel or in single user mode. As such we are at the point of not knowing how to proceed. If you have any ideas please let us know so that we can try to get this up and running.
We had a new hard-drive put in two weeks ago, due to FSCK failing.
I'm in the process of transferring my sites over to a new VPS, which is running CentOS and plesk. The server is also running PHP4 and MySQL4, both of which have to be upgraded for one of my sites (the site depends on PHP5 specific functions and MySQL referential integrity stuff)
So, to begin with, I installed yum to make my job easier. That went without a hitch. Then I did a yum check-update to see what was going to update...among the list was php and Mysql...excellent. When I issued yum update, however, I got a failed dependency error, and for the life of me, I can't solve it. Hoping a centos/plesk/linux guru can help me out here...
