I appreciate your help. about MTU: I visited some web sites including the wikipedia. I do not think I understood everything correctly about MTU.
I did not customize MTU. MTU must be default setting. I think MTU is automatically set. Anyway,I typed, ifconfig eth0 MTU 1500 and tried to browse www.google.com , but the page can not be accessed. about other Google pages: www.google.co.jp :server can not be found www.google.co.nz :server can not be found www.google.com :server can not be found I get the same result. _______________________________________________ Mailing list: https://launchpad.net/~launchpad-users Post to : [email protected] Unsubscribe : https://launchpad.net/~launchpad-users More help : https://help.launchpad.net/ListHelp
