RE: connection issue



fixed

I ran the arp -a from another machine on the same subnet of course. The
250 did not show. I changed the machine with the 250 to the 249 and it
doesn't show either yet it still connects to the I.

This is a laptop of an employee who travels to multiple plants with
different subnets. We have a static IP address for him at each of those
locations that he changes his laptop too. The 250 IP address is the only
one causing him fits.

Jeff,

What about running 'arp -a' from the pc at 249 - can you see 250 in
there..or does it give you any ideas.

No firewall or routers should be blocking the reply (multiple Windows
7 machines at this location connect to the system I with no problems).
The traceroute from the system I bombs on the first hop with the
following TCP error

Message ID . . . . . . : TCP3262

Date sent . . . . . . : 10/17/12 Time sent . . . . . . :
09:13:13


Message . . . . : 1 * * *



Cause . . . . . : For hop 1 no response was received within the
specified

time to probes 1 to 3.

Same error for the next two hops.

I would almost bet if I were to end TCP/IP and restart on the I that
would resolve the issue (of course that's a weekend type thing). IT's
been a while but I've had a similar issue at another remote location.

Are there any firewall or routers in between that are blocking the
reply from the iSeries? Can you run a TRACEROUTE from the iSeries
back to the
.250 IP address and see where that fails?

No point to point. The two locations are on a different subnet is all.

"bombs out" is a bit techie for me. Could you simplify that by
telling me the error message id and any reason codes or such stuff
that
you get?
Does that new IP address show up in NETSTAT?

Good morning,



I've had this issue before. I don't remember what I did to fix it though.
I
have a laptop at a remote location. If I assign it IP address
10.50.130.250
it will not connect to the system I (V6R1) using Client Access. If I
change the IP address to say 10.50.130.249 it connects to the system
I with no problems.



Using the IP address 10.50.130.250

I've tried the CWBPING and receive error CWBC01003 Socket error,
function connect <> returned 10060.

I can't ping the system I from the PC. I can't ping that address
from the system I either.

I've performed a tracert from the PC and I can see it connect to the
router at the remote location and the router at the location of the
System I then it times out.

I've performed a traceroute from the system I and it bombs immediately.



When I try to connect from the PC I can see a job in the TCP/IP
status area



10.50.130.250 50665 telnet 000:00:11 SYN-received



This job goes away after a short while.



If I perform the above with the 10.50.130.249 address everything
works fine.
I have multiple devices at this location that access the system I
with no issues.



The 250 address might have been used by another device at one point
in time.
It's almost like the system I is holding something from that
connection (mac address or something), not allowing the new device to
connect with that address.



The difference between the two IP addresses is one has full internet
access the other address is filtered through a website filtering
device. I've worked around the issue by opening up the 10.50.130.249
address to full internet access but I'm still curious as to what the
issue might be.







Thanks,



Jeff

subject: RE: connection issue

Yes the .250 reached the iSeries but the iSeries response did not make it
back to the .250 address. Can you set up two PC's, one at .250 and one at
.249 Login from the .249 and trace from the iSeries to the .250 address.
Check your routing tables on the iSeries to see if there is some special
route for the .250 or a misconfigured subnet mask.
