For me application like Evolution mail, youtube-dl, PUBKEY etc. dont work and I checked the MTU to be 1472. At my work environment the MTU is 1500 and there all these applications work. Is the problem just with the MTU? and would changing that make all of them work for me? I am just being a bit cautious so that changing it doesn't disrupt my present scenario! Also I haven't understood how to change the MTU permanently. at /etc/network/interfaces the following two lines are written: auto lo iface lo inet loopback What do I change now? What is the point in reducing the MTU?

What do I change now?
