Personally I always run firewall, so just remember about it all the time. >- Less efficient than certain UUCP protocols or ZModem for really slow or >half-duplex links Well, technically it should be of course slightly less efficient because of PPP, IP and TCP header sizes, but with high MTU it should be not so considerable overhead. The main issue is window scaling algorithm and TCP on null-modem and similar links is good enough. Also PPP exists in OS (*BSD) out of box, comparing to UUCP or ZModem-utilities. And also it allows online protocol usage immediately. I am not trying to persuade PPP usage, just personally my struggles stopped me at that solution :-) -- Sergey Matveev (http://www.stargrave.org/) OpenPGP: CF60 E89A 5923 1E76 E263 6422 AE1A 8109 E498 57EF
