SFTP

robert70 — Tue, 25 Aug 2009 13:12:59 GMT

Trying to SFTP between an Alpha Server VMS 7.3-2 (SSH (V1.0) 2.4.1) and a Remote FTP Server. It connects ok and you can change directory ok but when you either take a directory listing or try and put a file to the remote server it hangs.
any ideas?

further to this I use a windows client version psftp.exe and this connects to the remote SFTP server ok and lets the commands ls and put work correctly
thanks

Some actual information on the "Remote FTP
Server" (which, I assume is actually a remote
SFTP server) might be helpful. Similarly, a
transcript showing the actual command(s)
used, with the actual output therefrom, might
also have some value (greater than that of
your vague description)

sftp2 egduser@128.8.204.122

sftp> cd /home/users/fosexe/feeds/data/egd/in

.

after the ls command the system just hangs

Does ssh into the target box work?

What does the following command show for diagnostics:

$ sftp "-D9" "user@host.example.com"

Are you using compatible (and valid) certificates?

Any firewalls lurking?

Any virtual LAN (VLAN) connections or managed switches lurking?

(These days, having another box working is basically meaningless in a non-trivial network environment. Even the journeyman network folks have available a veritable arsenal of tools expressly designed to prevent network connectivity.)

yes ssh into the target box works

Robert,

you appear to be runnnig an unpatched version of TCP/IP Services - and the early versions of SFTP were riddled with bugs.

Try updating the TCP stack.

You don't say whether "ls" works after the initial connection. I've encountered issues in the past with SFTP getting lost after changing directories. Perhaps this path is just too deep (I've not had occasion to try one with 14 levels). If "ls" does work upon initial connection, you might try marching down the directory tree and see where the failure occurs.

sftp> ls
sftp> cd /home
sftp> ls
sftp> cd /home/users
sftp> ls
sftp> cd /home/users/fosexe/
.

"ls" fails whenever you log in

How do you update the stack?
thanks

How do you update the TCP/IP Services stack? Well, by coincidence, I just answered that in another thread:

does it matter if I install the JA release of this?

Robert,

I think that this is the JAPANESE kit!

Go through the itrc search page:

If you want direct FTP access, use

ftp://ftp.itrc.hp.com/openvms_patches/alpha/V7.3-2/

Right. The headless chicken who organized
this stuff spread it around pretty well. It
often helps to start at:

ftp://ftp.itrc.hp.com/openvms_patches/

and then explore more branches of the tree
than you would reasonably expect to be
useful.

> Am I looking at the right kit here?

No. The JA variants are the Japanese language variant kits.

Read the associated text files, too. Those files are the release notes for the kits, and (bluntly) there can be the occasional, um, surprises lurking within some of the patch kits.

As for patch area access directly from an IP-connected OpenVMS box:

DIRECTORY /FTP /ANONYMOUS -
ftp.itrc.hp.com::"/slash/path/to/file"

and

COPY /FTP /ANONYMOUS ...

There's also the master listing file (over in the OpenVMS directory) that is worth a read.

If you're running Mac OS X, you can typically run all this processing right from Finder, including reading the release notes text files and the patch download.
