cant FTP to any other hosts from my server

Praveen — Wed, 07 Oct 2009 07:50:11 GMT

Hi All,

I am not able to FTP to any systems from HPUC 11.23 server. If I run,

#ftp

it immediately returns saying "unknown host". I tried IP address, but didn't help. To me it appears to be ftp deamon problem on my HPUX server. Any help in this regard is very much appreciated

Thanks and Regards

Praveen...

What error message did you get when you tried with IP ?
Are you sure I is correct ?

and check this out:

netstat -a |grep -i ftp

Hello,
"unknown host" means that the system cannot resolve (convert) the name to an ip address.
a quick solution is to add the host name and ip address to /etc/hosts .
If using the correct numeric ip address also does not work you do not have a network connection to the other system.
You will need to fix the problem with your network .

As usual, seeing the actual command with its
actual output might be more helpful than a
vague description or interpretation.

To me, it appears to be a name look-up
problem on the FTP client system. Does any
other similar command work any better than
FTP?

telnet
rlogin
[...]

> netstat -a |grep -i ftp

Great. That will tell you about your own FTP
server.

Where "your network" means name look-ups on
the HP-UX system you're trying to use as an
FTP client.

are you using the correct IP address? try pinging the ftp server with IP address and with hostname.

if it works with IP address and with hostname doesn't, then there's a problem with name resolution. look for /etc/hosts and /etc/nsswitch.conf files.

if ping doesn't work either with IP and with hostname, there's a problem with your network.

Hi,

Login into destination host and try do a self ftp ? if you are not able to do then your ftp service is disable.....

ftp localhost

See what is the error message you are getting.

Who here believes that a dead FTP server can
cause an "unknown host" error message at the
FTP client?
