Hi, Admin
I have some problem with zero tcp window size on HPUX11i Bundle Dec2003.
The 3rd packet have tcp window 65535 and length 1 in the first example. It's
wrongly. But on Solaris it has 1 packet (it's 3rd packet ) which set tcp
window size to non-zero. It we can see in second example.
Can I update HPUX to establish successful tcp session?
The server is wap.e-port.ru.
Example HPUX:
