Debian Hardware :: HDD Change On Server?
Aug 25, 2010
Recently we have upgraded our hotel maintenance software, which uses databases and is running on Debian. We bought a HP ProLiant ML 110 G5 server for running the softwares. We experienced very slow speed on the network but after several tests, the result was that either the server or the software is the cause. We think that the software is the cause, but the provider of the software thinks it is the other way around. There is also HDD mirroring.
We have a same server except for memory. Our suggestion was that we move the two HDDs from the allegedly faulty server to the other one and than test the older server. But the provider of the software told us that this is not possible, since after moving the HDDs the mirroring might go bad and if the OS does not recognize the new hardware the OS could be damaged and than we will not be able to run the software.We were wondering whether this is a plausible scenario?

It's been awhile since I've posted.
I am curious as to the best and most practical way to change a desktop install into a server install. In other words, I want to get rid of X and KDE and all the extra software related to the two and have a purely command line interface.
I have discovered that having a GUI in a server context is kind of pointless, and when upgrading software requires a lot of time to upgrade the extra software related to X and KDE. I just want to clean it up and make it lean and mean.

I am running Debian (Lenny) as my file server on a Windows network. I have multiple users accessing shared excel worksheets. I am the owner of these files and have no problem but if I save a shared workbook the file properties on the Linux server change ''Groups - Read Only, Others - Read Only''. I can reset them logged in as root but they change back every time I save the file from the XP machine (XP Home SP3). All other non-shared worksheets are fine.

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

I have just configured CentOS server my new office. This is the first time I am using CentOS.
Whenever I am trying to change the webroot of the httpd server, it usually say "directory doesn't exist". whereas which can't be the case as it is home directory of the user.
To achieve this, what Do I need to do?
The second issue, I am facing that whenever I am adding new directories to public_html folder, it is not accessible. as the error page 404 is shown. I have changed the permissions to 0705 and ownership is also transferred to other user. What else is required to make new directories accessible by the web?

I installed Apache server with Debian 5.0.2 Lenny. I am trying to write a script which would analysis web log files. I found the log files on /var/log/apache2. There is an access log file, `access.log`. My question is what configuration file determines the location and the name of the access log file. How can I change them? I used CustomLog in /etc/apache2/apache2.conf like below.LogFormat ": %h %l %u %t "%r" %>s %b" common
CustomLog /home/test/my_log_file common Apache2 generated /home/test/my_log_file. But no logs were written in the file even after I run `/etc/init.d/apache2 restart`. Ichanged the log file location. It still didn't work. However, Apache2 still wrote logs in the file `/var/log/apache2/access.log`

I installed Debian Squeeze with Gnome today. I'm unable to change from the default icon theme. I can change themes, but the icon theme remains default.Things I've tried:
- I've made a new user account.
- .gtkrc-2.0 in my home is auto-generated, .gtkrc.mine does not exist.
# -- THEME AUTO-WRITTEN DO NOT EDIT include "/usr/share/themes/Darklooks/gtk-2.0/gtkrc" include "/home/haunted/.gtkrc.mine"
# -- THEME AUTO-WRITTEN DO NOT EDIT
- I've tried installing a theme into my /home/.themes.
- I've reinstalled gnome-settings-daemon.
- Tried changing themes then doing a full reboot.
- Cursed it periodically.

I've a popular vbulletin forum (10k max in vbulletin stats 'whos online') runnin in two servers like this:
1) Web server running vBulletin.
Dual Intel E5620 @ 2.40GHz (shows 16 cpus)
12 GB RAM
2 x 500 GB SATA (one for system/web and other for backups)
CentOS 5.6 64 bit
Apache/2.2.17
PHP 5.2.16
2) MySQL 5.server
Dual Intel E5620 @ 2.40GHz (shows 16 cpus)
16 GB RAM
2 x 500 GB SATA (one for system/web and other for backups)
CentOS 5.6 64 bit
MySQL 5.0.77
Web server connects to MySQL using private LAN.
Web-php server works with xcache as recommended by vBulletin.
Image/avatars and other static files (css, js, etc) are on a CDN
MySQL server uses Memcached for caching common queries.
The problem I'm facing, is from time to time (let's say one or two times a week) the Web server goes into read only mode... then the server has to be rebooted in order to get online normally and be able to work. From the logs I've seen this:
Code:
This is a new server, and in the old server the 'read only mode' issue happened very often too... so I guess it's not a HD issue.. it's just the HD have a heavy I/O usage. What do you think?
I am thinking about this solutions to improve the webserver performance:
1) 75% of the vbulletin users are anonymous users, so I've been thinking about using Cloudflare as a cache for all that traffic, that would reduce the php-webserver process a lot.
2) Using an external email server is a good option I guess... as right now the webservers also handles the email notifications for all the vbulletin users and it is constantly sending email everywhere. So, email will be stopped to gain server performance.
3) Mounting partitions with 'noatime' at /etc/fstab seems to improve I/O performance.

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

1. In the /etc/syslog.cong,
2.Change the line in /etc/logrotate.d/syslog
3. In /etc/vsftpd/vsftpd.conf
After the changes , i restarted the service for both ftp and syslog

I tried to change hostname through ssh.
Old hostname = server1
New hostname = server1.domain.local
I changed the hostname by editing the /etc/hostname file
Old:
/etc/hostname
server1
New:
/etc/hostname
server1.domain.local
Then I executed /etc/init.d/hostname.sh, and get as below, looks OK!
hostname -f
server1.domain.local
hostname
server1.domain.local
hostname -s
server1
The logs are still just showing server1.
Example:
tail -f /var/log/auth.log
Apr 15 13:30:01 server1 CRON[22783]: pam_unix(cron:session): session opened for user root by (uid=0)
Apr 15 13:30:02 server1 CRON[22783]: pam_unix(cron:session): session closed for user root
Do I really have to reboot, or is this normal behaviour that it does not show the full hostname?

I have these installations:
1. Wheezy on SSD (/dev/sdb) in one single partition (50GB)
2. Squeeze on HDD (/de/sda) with /boot, /root and /home.
Both drives are ext4 and they share one single swap partition.
I normally run wheezy on ssd since it is much faster. But, I have to log into my /home in squeeze in order to access my data there.
Is there a way that I can change wheezy to use the /home in the squeeze (second hdd)?

I just installed Debian and on the desktop are a few icons that have hideous icons. I was learning to just deal with them, but then I made a launcher for firefox and it gave me this spring-with-a-platform icon that just crossed the line for me.......
How can I change the icon pictures so that they actually represent what they are? I want the firefox launcher to just be the normal earth-with-orange-fire-thing firefox icon.

I am currently using a shell script to run a java app which performs some integration logic. The shell then continues to compile a file with all stats resulting from the java app. I then send this compiled stats file to several emails. The email is from 'root'. Is there anyway to change this without having to create a new user and running this app as them instead.
