From: giant@proton.giant.org (Chien-An Chen) Subject: [Q] MTU? Date: 26 Jun 1993 05:36:11 GMT
Could someone explain what's "mtu"? "man ifconfig" tells me MTU = Maximum
Transfer Unit and says it should be set to 200 - 4096 for SLIP connection.
It is also noted that, for the current implementation, I should set the
value LARGE ENOUGH. ENOUGH is quite fuzzy for me. :-) Anyway, when I set
mtu=4096, all network clients hang on me after few minutes (some, like trn,
almost hang immediately). But when I change mtu to 296, everything is fine.
why???
BTW, when I login to SLIP server and type "slip", the server responds with
an ip address and mtu=1500. If I set mtu=1500, it's half chance clients
hang in a few minutes.
