TCP window size

[Amitava_HP-UX]

How can i know what is the TCP window size in my Tru64 unix 5.1B system. I want to know it as my FTP is slow. I also want to know how to modify it & what all re the possible values of it. How to determine the best value.

Hi,

look with sysconfig -q inet for
tcp_recvspace
and
tcp_sendspace
There is also a file /etc/iptos

greetings,

Michael

hi
thanks for your valuable information. I could not find any file /etc/ipots. but this info served my purpose.

How slow is it and over what kind of connection?

I doubt that you need to tune the TCP window size to get good speed. It's more likely that you have a network problem, such as a badly negotiated network connection (e.g. half versus full duplex). What kind of interfaces do you use and how are they connected?
