Dear readers,
Today I am going to show you how to solve a very very very hard problem in a very simple manner. If you are using Linux and Ringo Cameroon PPPoE or if you are using PPPoE or any other method to connect to the internet and then all of a sudden the following happens then read on:
- You can browse some websites but not others
- you can ping a website but cannot open in browser
- you can telnet a website but cannot open in browser
- you can traceroute a website but does not open in browser
- filezilla loads and stops just before opening a remote directory
- your skype works while facebook chat or empathy messenger will not
- your internet suddenly slows down and sites fail to open
if any of the following is happening then you MIGHT be suffering from what plagued me for 7 days. The problem is not your DNS or iptables or anything, it is the size of MTU. Yes.. for some reason the MTU might change without notice (I do not fully understand this yet). So all we have to do is set you MTU to the normal size which for PPPoE connections is 1400.
So just open a terminal and type this command:
/sbin/ifconfig ppp0 mtu 1400
Then press enter and you are done. Solved. (this took me 7 days to figure out)
Thanks for reading
