RE: ftp to vendor system failed


Still fighting this issue, but know more.
Nslookup verified ftp dns as well as by ip
No ssl required and ssl not configured on this box.
This is message after timeout.

Message ID . . . . . . : TCP10B0 Severity:. . . . . . . : 10

Message . . . . : Cannot connect to host x.x.x.x at address . Try again
later.
Cause . . . . . : A control connection could not be established.
Recovery . . . : Try the command again later.

Google does not have much ..
Anyone find that talking to an Amazon hosted ftp server any different?

FTP from pc on same lan to same address, through same firewall works ..
6 other ftp processes all working well through same firewall to other
servers.
Similar scripts, just different logon and different file names.
Reasonably up to date on ptfs. This is V7R1.
There are two Ethernet ports, both connected to same lan, both route through
same gateway.
Noticed that the 2 have different SSAP. Nothing that points ftp to a
particular line.
No exit point for ftp client.

Plan to try something like FTPAPI this weekend..

Jim

Back in the day running SENDPA command before the PUT fixed a lot of NAT
issues.

I think the term you are looking for here is NAT or Network Address
Translation. It's basically the thing that changes your 10.x.x.x
address into something else on the outside.

Sometimes certain ftp sites require people coming in have a certain IP
address. Then you end up putting something in NAT that your address
internally always maps to this on the outside.

We used to do this but the fluidity of the internet had us turn that off.
For example the major customer who used FTP but the gal doing it often
did it from the local coffee shop when she started night school. The
kind of customer that when then say <excrement> you squat and ask "what
color?".

ftp server rejects ping from both Win and i .
i think this will end up being a firewall issue if diff public ip used
on the external side of the firewall.

Firewall or could their system be rejecting the IBMi FTP for some
reason
?

If a simple connect works from Windows it should from IBMi.

Try host name and IP ?

Can you ping it ?

subject: ftp to vendor system failed

I've used very simple ftp to other systems for decades.

Not sftp. Plain old ftp.

I can access other system via windows ftp with no problem, prompts
user, prompts password, connects.

Standard port 21.

No

Power i from command line or clle using a source member script - gets
stuck in TIMW status - no error message , just hangs.

No prompt for user.

Same system uses ftp to multiple systems every day. They still work.

As far as I know it's a Win or Linux system at other end.

V7R1

Any ideas - am having firewall reviewed.

Jim
