Server :: Move The Server To It's Own Machine?
Mar 29, 2010
Im running my website on a Debian machine that started to get high load so i wanted to move the mysql server to it's own machine. and here is the problem. The second machine is also Debian and is behind a router only running mysql. i have forwarded the port 3306 to the second machine and created an A record for "mysql" so mysql.mydomain.com points towards the second machine. However, when i try to connect my websites script to the second machine i get the following error "Warning: mysql_connect() [function.mysql-connect]: Lost connection to MySQL server at 'reading initial communication packet', system error: 111" when i open the site in a a browser.
edit: i can connect to it without a problem localy trough phpmyadmin etc.

I've got 4 identical 1 TB drives and would like to use them in a software RAID configuration on my home server. I'm running Debian Linux using 'mdadm' utility to manage the software RAID. I don't know how much I've read is fact or dated or even false so I decided I would ask here to get help from people who know more about this than I do. This is essentially just a file server machine to store all my data so being that I've got four identical SATA hard drives, I was thinking about doing RAID level 5. I guess I'll start here and ask if that is the recommended level of RAID. I think RAID level 5 will be fine for my general server usage. My second issue is partitioning the four individual drives to get maximum performance / space from them. Basically just asking here how would you or you recommend I partition the drives? I was thinking about doing three seperate partitions per drive:
/dev/sda1 = 4 GB (swap)/dev/sda2 = 1 GB (/boot)/dev/sda3 = 995 GB (/)Now from that partition schema above, obviously all the types will be 'fd' for RAID and the partition for /boot is going to be bootable. My confusion is that I read Grub doesn't support booting from RAID 5 since Grub can't handle disk assembly. If /dev/sdx2 (sda2, sdb2, sdc2, sdd2) are partitioned for /boot (bootable), how would you guys configure this RAID to match up equally? I don't think I do a RAID level 1 on 4 identical partitions, right?

I have a qmail mta that needs to be moved to another server. The current host system will be discarded due to end of SLA for the hardware support.
The qmail mta is setup according to the guide on [URL]. There are currently about 10 postboxes and about 30 forwards defined with a total of about 1000 emails.
I don't want to send each old mail to a backup postbox outside qmail and resend it back after I setup a new qmail mta on the new server.
I would like to setup qmail in a configuration where each mail would be automatically replicated on the qmail mta, where the new mta would take over duty when the old one will shutdown. Anyone had a similar project and know how to do this? If not does anyone know how to move a qmail install onto another new system? Or may be how to export and import the postboxes and forwards?

I need to access a Windows Server 2000 machine using a Linux machine via KDE, but that will migrate to Gnome. The Linux user to connect to Windows machine, you should open an application 'XYZ' automatically, and only this, denying any unauthorized access. When you close the application 'XYZ' communications (RDP?) Should be terminated. Do I need a log of accesses and possible attempts to circumvent the system and access other application.

I have a DNS server at an old companies place and that box will be losing it's IP. The whois record for the domain goes to godaddy which has 2 'A' records;
ns.domain.com
ns2.domain.com which point to the current 2 DNS servers. Now if I have a new server up and running and the zones copied over, do I just need to change the 'A' location for ns.domain.com to this new IP? I remember back in the day you had to 'register' the nameserver with the registrar, etc.I haven't touched this stuff in a while, and before I go and change the IP of the nameserver, want to make sure all is in check.

As a Windows user, I generated a pair of DSA keys from CoreFTP Lite and sent it to a third party that runs an SFTP server. They told me that a valid DSA key needs to have ssh-dsa at the start and the username@systemname at the end. CoreFTP generated neither the ssh-dsa header nor the username@systemname footer. I tried with WinSCP and it didn't generate them either. Is there a difference between how SFTP works between Windows and Linux? If I put a useraccount@systemname at the end of the text will it work? How would the Linux system validate that my system is called "systemname"? If it can't validate, what is the purpose of adding it?

I have a very basic "working" Dovecot configuration from 1.x as shown below:
Code:
auth_mechanisms = plain login
mail_location = maildir:~/mail
passdb {
[code]...
My question is I've built a new server and now it has Dovecot 2.0.11 & I would like to know if I need to generate a new configuration file or will the above 1.x work in 2.0.11? The configuration file 'dovecot.conf' generated by 2.0.11 is all commented out and I don't know what I need to uncomment / add to the config to get IMAP working.
Code:
[root@mail /]# doveconf -n | head -2
# 2.0.11: /etc/dovecot/dovecot.conf

I have an email server running postfix and popa3d under Debian. I have mailboxes in mbox (single file) format per user in /var/mail/username. I had my own mailbox get too many messages so popa3d refused to process per a compiled in security / anti-DOS limit, so I moved to /var/mail/username_bak. What is the best way to start moving the messages from /var/mail/username_bak to /var/mail/username? I do not see any utilities included with postfix or popa3d that do this, but I am hoping there are generic mbox utilities to easily do this.

I'm in the middle of moving my lab to a new server in the middle of the school year.. and need to copy all the user accounts to the new box, hopefully with all the student's passwords and contents of their folders intact.And since we are using the system daily, I need to do it all in an hour or 2.I'm thinking I can just
1. diff /etc/passwd and /etc/shadow from the old the new
2. copy all the student folders to new /home
3. write a script to set the permissions on all the new /home folders to match the user names.
It seems easy and safe so long as I back up the 2 existing files..Any reason not to try? Or is there an easier way?

Currently running mythbuntu 10 and I'm trying to write a script that will move the *.mpg recording onto my server when it has finished recording. It is automated so I need it not to prompt for the password.
This is what I have so far:
1) System events, when finished recording: /var/lib/mythtv/mover.sh
2) mover.sh (chmod +x)
Code:
#!/bin/sh
#this is to move the files after recording locally
#to a unRaid box (reiserfs conflict)
sudo mount {server ip address}:/mnt/cache/ /mnt/pvr
sudo mv /var/lib/mythtv/recordings/*.mpg /mnt/pvr
3) sudo visudo
Code:
{name of pc} All = NOPASSWD: /var/lib/mythtv/mover.sh
This is my first script and I don't know too much so go easy, but I'm not sure what I'm missing.

Is there a simple way to move the Sendmail queue folder? Presently it's at the default location on /var/spool/mqueue/ but when / recently ran out of space (my fault storing backups there), it was unable to receive any more mail. There is plenty of space at another partition. My /var/opt/scalix location lives on another set of discs with lots of room. I created a folder called /var/opt/scalix/sendmail/mailqueue/ but uncertain how to move the existing queue to it.

I just installed mysql and need to move the databases to a new location.I say 'no problem' I shutdown mysql (service mysqld stop) I configure my.cnf to point to the new location, which in my case is: /mnt/data/mysql. I know not very original naming. I do the old chown -R mysql:mysql /mnt/datal/mysql AND I copy all the files over (cp -R /var/lib/mysql /mnt/cgsvol/mysql) chmod 777 /mnt/data/mysql I ensure the chown worked (ls -a -l) and the files are there from the old directory. I can't load the daemon again. I check the log (/var/log/mysqld.log) and it can't write any test file to that directory.
(log file exact data).
