Repairing MySQL tables that will not open.

This should be handled on a case by case basis, but if you are using the default MySQL table type of MyISAM (which is the default storage engine unless changed or specified differently) here are a few options:

  1. The myisamchk utility can be run from a command line to checks, repairs, or optimizes tables. It is normally run while the database is not running. For more information about myisamchk visit the MySQL website.
  2. mysqlcheck is similar in function to myisamchk, but can be run while the database is running. For more information about
    mysqlcheck visit the MySQL website.
  3. If you login to the database, you can also run sql commands that might fix your problem.
    mysql> optimize table your-tablename;
    mysql> analyze table your-tablename;
    mysql> repair table your-tablename;

    For more information about
    table maintenance SQL visit the MySQL website.
  4. If you are getting MySQL error numbers and are not sure what they are. From a command line you can use the perror utility to lookup errors. For more info on perror visit the MySQL website.
    shell> perror 13 64
    Error code 13: Permission denied
    Error code 64: Machine is not on the network

Need to change IP address in FreeBSD

Issue: A change of IP address is needed in FreeBSD.

Solution: If you do not have the root password boot into Single User mode [option 4]. Procced to step 1.

If you have the root password procced to step 2.

1. mount -o (if you get a read-only error, you will have to run fschk -y)

2. vi /etc/rc.conf (If vi is unavailable use ee)

at this point simply edit the IP Address lines that will need to be corrected.

How to block ip addresses with iptables

I have an ip address attacking my server or taking up all my httpd connections so none of my sites work.

In order to correct this you will want to use the netstat -n command to see the ip addresses connected to your server. Once you have the ip address you want to block you can use the following command to block them from accessing your server using iptables

iptables -I INPUT 1 -s IP.ADD.RES.SS -j DROP

-I INPUT 1 means to insert the rule at the top of the INPUT table (which means it will get looked at first)

-s IP.ADD.RES.SS is the source address of the packets we want to deal with

-j DROP means dump the packets into the void, and forget they ever happened.

How to forward a website to another url using PHP

There are several ways to accomplish this task, but the simplest to understand is to use php.

To do this, you need to create the page that will do the forwarding. This can be any page, as long as it ends in “.php”. If you are trying to redirect a domain, you’d create “index.php” inside the public_html directory.

Once you decide which page you will use, then create the file and enter the following text:


Where is the location that you want the page to forward to. You can use local values, ie: /page.html, or full urls as in the above example (http://..etc.)

Plesk Migration Manager is unable to connect to Plesk Agent installed on a remote server.

Source server has Plesk Migration agent installed. Plesk Migration Manager is installed on Plesk server. Plesk keeps displaying

Unable to upload scout: Unable to run migrmng: Unable to connect to remote host Please check if the remote server is available for connection and if the correct login and password are specified.

To successfully utilize Plesk Migration Manager it’s important to have the network setting configured correctly:

1. The following ports need to be open for PMM (add the required exceptions for firewall):

For PMM:tcp 6489 (by default or other custom)

For data transferring on Windows source servers:tcp 135tcp 139tcp 445udp 137udp 138

For data transferring on Linux source server:tcp: 22

2. Server’s network settings. “Client for Microsoft Networks” and “File and Printer Sharing for Microsoft Networks” must be present.

Start, Settings, Network Connections, Local Area Connection click Properties button. “Client for Microsoft Networks” and “File and Printer Sharing for Microsoft Networks” should be present. If they are not, they need to be installed.

You can test connection to server with PMM Agent using

Start, Run, type \\хxх.хxх.хxх.ххх\c$ and hit Enter

where xхх.xхх.хxх.ххх is the IP address of the source server.

And if “Network sharing” ports are opened you can access windows administrator’s share folders.
