the problem is pulling a file from khupepc001 when you are logged into khepx019..

if this is not what you are asking please let me know, i am a little confused on this part.

[marvin51796]

here is the netstat -rn from another system it still doesnt work from.

which of these is test1? and which address do you aim at when doing the test that is slow? 

[marvin51796]

we are logged into khepx019, and are doing a scp khupepc001:/tmp/aectst /tmp/aectst and it takes like 5 minutes, if i am logged into either of them and do a scp /tmp/aectst khupepc001:/tmp/aectst  it takes 5 seconds.

and according to our EMR people this is a major problem.

[marvin51796]

i guess the commands are really setup like this

if logged into khepx019 and isues a scp khupepc001:/tmp/aectst /tmp/aectst it takes 5 minutes

if logged into khepx019 and issues a scp /tmp/aectst khupepc001:/tmp/aectst it take 5 seconds

if logged into khupepc001 and issues a scp /tmp/aectst khepx019:/tmp/aectst it takes 5 seconds

hopefully this is a little clearer.

[Ken Grabowski]

From  khepx019 try using individual IP addresses not host names and use each of the IP's that they have. See if there is any difference in the time it takes.

[marvin51796]

logged into khepx019 doing a scp 172.27.104.54:/tmp/aectst /tmp/aectst takes the standard 5 minutes.

doing a push from khupepc001 scp /tmp/aectst 172.27.104.37:/tmp/aectst takes 5 seconds

doing a push from khepx019 scp /tmp/aectst 172.27.104.54:/tmp/aectst takes 5 seconds.

[Ken Grabowski]

whats the time for:

 khepx019 doing a scp 172.27.103.214:/tmp/aectst /tmp/aectst

[marvin51796]

5 min

[Ken Grabowski]

Also, while the 5 minute scp is occurring, what is the connect on the remote system?  netstat -an and look for the "ESTABLISHED" line from the originating server.
