Re: FTP problem

Jim Many thanks.

If I telnet to the local address on the V5R2 server, I get through.
If I FTP to the same local address, I cannot connect and get the message

Connecting to remote host xxx.xxx.xxx.xxx using port
21.
Cannot connect to host xxx.xxx.xxx.xxx at address XXX.XXX.XXX.XXX. Try
again later.

Could the port be the problem?

Possibly but I'd like the test with TELNET or FTP to the specific address
(do not use the host name) to discover how that reacts.

So TELNET xxx.xxx.xxx.xxx and see how that reacts. You might try FTP too.
If they work the problem is most likely a simple one in the host table
and/or Relational Database Directory Entry. If they do not work it's
likely
the router/firewall is the issue.

Jim,

Many thanks.

As I said, I can ping the internal adress. Could it be a port problem
blocked by the router?

Another thing to consider. Ping uses UDP not TCP. If there was a
router/firewall change, is it blocking or not routing the TCP and
allowing the UDP through?

For grins try TELNET (or FTP for that matter) to the specific
address, not to the host name. If that works it's not the

router/firewall.

I wish I knew more in this area but here goes ...

The Change TCP/IP Domain (CHGTCPDMN) shows the IP address of your
domain name server.
Is this still correct?
If it is correct and you can reach the domain name server, does the
domain name server know about 'myhostname'?

I recently had to change a router and this has caused a variety of
problems.

I changed the RDB entries on a V5R1 server to reflect a new internal
IP address for a V5R2 server on the same network, but when I execute
the command STRTCPFTP on the V5R1 server and enter the RDB name for
the V5R2 server, I get

TCP101A - cannot find 'myhostname'.

Yet I can ping the internal address stored in the RDB definition for
the
V5R2 server without problem, both from Windows and using the ping
command on the V5R1 machine.

I wonder (ignorantly!) if the problem is with the router
configuration (which I didn't set up).

All help gratefully received.

many thanks
