Network services, that doesn't work corectly

Bakos György — Thu, 04 Dec 2003 06:46:39 GMT

I had a forum in
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=290491

I have now only problems with network services, they are not ok.
ftp:
Conection closed by remote host

telnet, rlogin are not working.

In sam they are enabled.

nmap 21port open

What could be the problem.
Maybe some permissions.
The host file is edited for this 2 machines.

First check the /etc/services file to make sure the lines for these services are not commented out (ie: no "#" sign at beginning of line). Then check to see if the services are running. A simple "ps -ef | grep " would do it. Also try connecting with the IP address first (not hostname). This will at least tell us if this is a DNS problem or if we can rule that out. Let me know what happens.

I would like you to check whether any duplicate ip is on the network.

Might be you are ping'ing another machine but no network services work!

Just disconnect the cable and try doing a ping to the ip.

Also check whether inetd is running

check whether the services are enabled in /etc/services and then check whether the services are not commented in the /etc/inetd.conf file and then do a
#/usr/sbin/inetd -c

Thanks

Any messages in the /var/adm/syslog/syslog.log file.

Try doing a #insf -e
to re-install all the telnet device files

registar/tcp: Conection from ltoux174(my host)

Then check

/var/adm/inetd.sec file

where there are restrictions
