How to change MTU size in Linux (all flavors)

A note to self.

We have a vpn issue where it is connected but can do nothing(ping etc.). Boss gave an idea maybe some MTU because of previous incident we have.

Fire up terminal.

/sbin/ifconfig usb0 mtu 1492 up

Viola, it can ping and even load some java apps on webs.
