ftp connection hangs after a long inactive time. [message #22778] Thu, 15 May 2008 07:52 Go to next message

Hi,

I am connected to a remote site which uses some
routers/switches/firewalls that drop a session after some idle time (I
read somewhere that cheap Cisco firewalls have that problem).
So every time I take a coffee break ssh and ftp sessions with or without
Eclipse hang.
Can dsdp target management be configured to restart a session whenever
that happens?

Thanks

For ssh / sftp, what version of RSE are you using?
We added a keepalive feature in RSE 2.0.3 / RSE 3.0M6, which
should avoid that kind of issues.

For FTP, I was under the impression that it does reconnect
automatically, in fact doesn't even notice the dropped
connection, or am I mistaken?

If I am mistaken, would you please file a bug (enhancement
request) for this?

Thanks,

I couldn't find where this setting is. Please guide me.

I had the same impression but I don't know how to verify that and
therefore I would avoid submitting a bug report until I know what I see.

Anyway, I changed to fssh which seems to get disconnected after every
file transfer and therefore avoids the problem all together.

Thanks for your help.

In the New Connection Wizard, below "SSH Connector Service" there
is an "SSH Settings" node. Select it and you can enter the
keepalive (default is 300 seconds, so RSE would send a keepalive
packet every 5 minutes).

If your connection already exists, select the host, right-click
> properties, select the "Connector Servcies" / "SSH Settings"
node, and voila you see the keepalive time (300 by default).

Window > Show View > Other... > General > Console
Click on "Computer" icon to switch to the FTP Log Console
You'll see the log of FTP commands so you'll see if and where
the connection is (re-)established.

In general, don't be afraid of entering a bug. In the worst
case, a committer will come and set it to "WORKSFORME" or
ask you to provide more information. Please, don't be shy.
Just see bugzilla as a communication platform, where the
comments (just as I'm typing right now) are stored in a
much more accessible, ordered and searchable database than
here on the newsgroup.

Cheers,
Martin

I didn't find the "SSH settings" node. Is it a version issue?
