How to setup timeout parameter for a ftp session ?

Deepu Chakravarty — Wed, 29 Jun 2005 02:35:47 GMT

I need to setup timeout parameter for a ftp session. So that it does not timedout for that period or unlimited connectivity time.

Hm, is it a single client's session that you want to timeout?

Otherwise I'd suggest to have a look at man ftpd.

On start of the FTP server you can pass the daemon a timout through -t
(if unset it defaults to 15 mins.)
Since ftpd is usually spawned through inetd you would have to add an apropiate argument in /etc/inetd.conf and send inetd a SIGHUP,
or execute /sbin/inetd -c

hi,

to change the default 15 minutes timeout, edit the system-wide /etc/inetd.conf resource file to start the ftpd with the -t 600 (for 600 seconds) option:

FROM:

ftp stream tcp nowait root /usr/lbin/ftpd ftpd -l

TO:

ftp stream tcp nowait root /usr/lbin/ftpd ftpd -l -t 600

to use this new value, restart Internet services daemon:

# /sbin/init.d/inetd -c

regards.

Hi deepu

Option 1:

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

the hash # will keep the ftp session alive as a # is transmitted every 10k of data transfer...
and this is a client side solution and will work any where for any user...

Option 2:

If variable need to be tuned then tune using nettune -s, tcp_keepfreq and tcp_keepstop values... as u hav not mentioned the OS version , iam putting the command syntax ...

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.

Sorry a few flaws.

1st the correct path is

/usr/sbin/inetd

2nd rather set -T of ftpd

and set an "idle" timer in your FTP client.

Thanks for the replies. But what to set for unlimited timeout session.

hi,

if u mean disabling the timeout, set the -t option to 0 (numerical zero).

regards.
(p.s. please remember to assign points.)

hi deepu,

if you do man ftpd, you will get the whole syntax details

-t timeout Causes ftpd to timeout inactive sessions after timeout seconds. By default, ftpd terminates an inactive session after 15 minutes.
