UNIX Desktop Questions & Answers

hi,

good morning.

Ma trying to ftp from one AIX machine to another on the same segment of the network. The ftp to eshtablish connection from machine A to machine B is quick, but the reverse is taking is much time (2 mins).

anyone can help me to solve this issue please

Could be tcp tuning -- small mss means few packets can be sent before awaiting ack. The receiving system sends the buffer size as mss and that is all the sender can send ahead of ack'd byte sequence #. Often systems are defaulted to 4 512 byte packets, nice on a dialup but silly on Ethernet. Usually sending something like 1440-1460 bytes a packet allows for headers in the Ethernet MTU 1500, and the mss can be some large mutiple of that (to stifle small packets) under 65535, or more with rfc 1323. http://en.wikipedia.org/wiki/Transmi...l_Protocol#RFC
