FTP Server HP-UX 11.0 Help

[Scott Callicott]

I have a HP-UX 11.0 server that is running FTP server on it. My users in the field are running Windows 2000 and are pulling and pushing data to this server. When my users are downloading a file from the HP I get a lot of disconnects closed by remote host problem. These files are 4-6MB in size going across a 56K modem. Now all there other access does not seem to do this ie Email Internet only the HP so I am looking for any help on settings etc on the HP side that might be causing this problem and how I might fit it. Thank you for your time.

First thing to do is make sure you have the latest patch bundle installed (Dec 2001).

How frequent are the disconnects?

As far as I know I am up to date on the patches on the box. The disconnects are getting to be a large issue they are happening more and more. Like 35% of the time now. The connection is still there with the RAS but the FTP itself disconnects before it is finished.

Hi,
Here is the doc How to increase the keep alive time for FTP Doc id # KBRC00000523

Instead of adjusting timeout variables, just enter hash at the ftp
prompt.
ftp> hash
then get your file
ftp> get filename

What this will do is present a # mark for about every 10k transmitted and will
not allow the ftp session to die no matter how long the session. The good thing
about this solution is that it is a client side solution meaning it will work
anywhere for any user.


2. If variables still need to be adjusted use the
nettune -s command. To increase the timeout increase two variables,
tcp_keepstop and tcp_keepfreq. Then make all of the variables present in a
startup script. The commands are as follows.

For 10.x
nettune -s tcp_keepfreq 1000
nettune -s tcp_keepstop 1000
for 11.0
ndd -set tcp_keepfreq
Use the netune -h command to print to standard output all variables that
are defined by nettune on your system.

So to academically incorporate the set_fin_time script to execute at boot-up,
you should create a compliant HP-UX 10.X start-up script.
