Greetings, For the past several months I've been having interesting problems with my internet link via the user level ppp program. Essentially any connection in which I attempted to send large quantities of data (ie more than what's generated by an interactive shell) would hang and enter a state of FIN_WAIT_1. I spent a little bit of time digging through the code, and came accross the `set mtu` command. I assumed then that this command would override the MTU setting. But to no avail, the connections didn't work. In the end my problems are mostly a problem with our ciscos; however, there seems to be a logic problem in so far as I couldn't overload the MTU setting to something other than the MRU reported by the ppp server. As much as I'd like to spend sometime digging through the source code to fix it myself, I simply don't have the time right now. For the time being a simple hack to one of the header files resetting the MAX_MRU and DEF_MRU to 552 has solved my problem. Danke --- Joe Diehl <joed@ksu.edu> PGP Key: finger joed@unix.ksu.edu
