TCPS_SYN_SENT in RST flag (remsh)

[Cristian_4]

Hi,

Im doing a remsh command from A to B, sometimes works and sometimes dont.

After a quick sniff to the network packets i discovered the following

working connection
1- A sends SYN to B
2- B replies SYN ACK to A
A- A sends PUSH ACK to B ... and everything goes fine after that

not working connection
1- A sends SYN to B
2- B replies ACK to A
3- A sends RST to B with TCPS_SYN_SENT-Bad_seq in the packet .... after that the remsh fails

A is a HPUX 11.0
B is a Sun 5.8

any ideas ?

Do you have PHNE_33159 installed? Is it relevent to your machne as you haven't posted details of what your HP machine is?

In particular :


( SR:8606311142 CR:JAGae73997 )
During connection establishment, an unacceptable sequence number is used. This sequence number triggers TCPS_SYN_SENT-Bad_seq RST from the peer which terminates
the connection establishment process.

Resolution:
The RST generation is avoided by not using an unacceptable sequence number when establishing the connection.
