Telnet Redhat 8.0 connection refused.

Hi,

Just installed redhat 8.0. Try to telnet the linux from remote machine. But today I just can't telnet it any more.

check the following setting:

# /sbin/chkconfig --list telnet
telnet on

# grep disable /etc/xinetd.d/telnet
disable = no

via lokkit I disabled the firewall and I also executed /etc/iptables stop

ied gnome-lokkit to reset firewall rules, tried redhat-config-securitylevel to change security level, but nothing seems working.

There is notthing in my checked /etc/hosts.deny file
also I set checked /etc/hosts.allow to ALL:ALL

Anyone can help? Thanks a lot.

Try running:
iptables -F

to remove all your firwall rules then if telnet works save them:
service iptables save

Then use lokkit to setup your firewall again.

I did what you asked but I still have the same problem.
This what I did:
iptables -F

Can you telnet to 127.0.0.1 from the server itself?

I'm not sure this will help or not I cannot ftp nither

david_ross · 05-01-2003, 02:03 PM

Do you have an FTP server running?

Did you restart xinetd?
service xinetd restart

saeed_zarea · 05-01-2003, 02:09 PM

Yes, yes. The ftp server and telnet are runing. I can see it [root@ftpserver /]# chkconfig --list | grep -i vsftp
vsftpd: on

[root@ftpserver /]# chkconfig --list | grep -i telnet
telnet: on

[root@ftpserver /]# chkconfig --list | grep -i xin
xinetd 0

What does your routing table look like?

Code:

route

how do you check for route tables.
FYI
[root@ftpserver /]# chkconfig --list | grep -i iptables
iptables o

Problem solved. /etc/xinited/telnet & vsftps files did not have an extra blank line at the files.
