There appears to be an error either in /etc/services or /etc/inetd.conf as there does not appear to be anything listening on port 21.

Are there any error messages in /var/adm/syslog/syslog.log?

Can you try running an 'inetd -c' and see what errors are reported and whether or not anything is generated in syslog.log?

Well, yeah. "Connection refused" made it
pretty clear that you aren't running the FTP
server.

Assuming that "services" was "/etc/services",
then that looks ok to me.

> 1) inetd[1501]: ftp/tcp: Unknown service

If "/etc/services" is ok, but you get a
complaint like "Unknown service", then my
guess would be that you're not looking at the
same "services" data as inetd is. Are you
running NIS? LDAP? (Something else about
which I know nothing?)

cat /etc/nsswitch.conf

What's the history of this problem? Did FTP
ever work before on this system? What's
changed recently?

Sounds like a "services" data base problem,
doesn't it?

[infarakesh]

ftp never worked I guess.

This machine is of NIS client.

# ypwhich
spyder.xxxxx

nsswitch.conf file never existed. I added an hr back.. no luck though

# cat /etc/nsswitch.conf
#
# /etc/nsswitch.nis:
#
# @(#)B11.23_LR
#
# An example file that could be copied over to /etc/nsswitch.conf; it
# uses NIS (YP) in conjunction with files.
#

passwd: files nis
group: files nis
hosts: nis [NOTFOUND=return] files
ipnodes: files
networks: nis [NOTFOUND=return] files
protocols: nis [NOTFOUND=return] files
rpc: nis [NOTFOUND=return] files
publickey: nis [NOTFOUND=return] files
netgroup: nis [NOTFOUND=return] files
automount: files nis
aliases: files nis
services: files nis
#

[infarakesh]

I understood that it's services problem.. how to correct it?

In fact, I restored the original file w/o any luck

[infarakesh]

# cat /etc/nsswitch.conf|grep -i services
services: files nis
#
