If you follow those guides about migrating your blog to another webhost using import/export functionally…
You must rebuild your permalinks in the exact same format as the original webhost!

Go to Settings > Permalinks, and click save changes.
Make sure you choose the correct permalink structure.

If you do not, all your indexed pages on search engines (google, etc) will disappear and your site will be re-indexed losing you your traffic.

So, you want to access a MYSQL server but you only have an SSH terminal…
Not to worry, you can use SSH tunnelling to do this!

Basic Example

Example: ssh -L 3306:localhost:3306 user@IP -p SSHPORT

Now how do you control this dark ssh sorcery? Let’s break it down.

1) 3306:localhost:3306

•  Open a port 3306 on my local machine to redirect
• localhost:3306 means we are tunnelling to 3306 on SSH machine

2) user@IP

This is your username and the IP address of the server

3) -p SSHPORT

This is the ssh port if it is not on 22.

Another Example

ssh -L 9000:192.168.212.1:5000 [email protected] -p 1234

You would use this if you wanted to:

• use your computer port 9000
• to access the port 5000 on IP 192.168.212.1
• through the SSH server 192.168.2.1
• with SSH server port on 1234

Happy SSHing!

I used the following source:

https://bowerstudios.com/node/731

I did this in windows using git bash that has ssh command. You can also do using cygwin or pure minggw.

1) Run ssh tunnel command in command prompt (I do this in git bash/MINGGW32).

ssh -D 9010 -p 22 root@IP -v

2) Run your application on server with JMX options

java -Dcom.sun.management.jmxremote 
-Dcom.sun.management.jmxremote.port=9010 
-Dcom.sun.management.jmxremote.local.only=false 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false -jar 
application.jar

3) Run visualVM through socks proxy to connect:

visualvm -J-Dnetbeans.system_socks_proxy=localhost:9010 
-J-Djava.net.useSystemProxies=true

4) Actually add your JMX remote connection in visualVM

If you don’t have space to write a dump file, or want to directly send your SQL to another server (without intermediate transfers), using a remotely mounted folder is a way to go.

There are various mounting options such as:

• SSHFS
• NFS
• Windows Shares (SAMBA)

The watch command can be used to repeat a command every X seconds.

Examples:

Monitor Disk Usage (updated per second)

watch -n1 df -h

Print Hello World (every second)

watch -n1 echo “Hello World”
