can't access to remote machine

abd_bela · 12-29-2002, 02:42 AM

hi,
I ve just reinstalled the redhat 7.3.
In the previous installation, i could access to my machine from another with telnet or ftp, but not now.
I have installed telnet server, ftp server ..., the services are check and also the xinetd.
I run the xinetd but the same problem: Connexion refused.
perhaps something is doing by the firewall ??
where can I test if the fire wall stops the entering

thank you for help

What firewall? I think the problem is in you /etc/inetd.conf. Edit it and uncomment the line with telnet an FTP:
#something like that
# File Transfer Protocol (FTP) server:
ftp stream tcp nowait root /usr/sbin/tcpd proftpd
#
# Telnet server:
telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd

It should be ok, or you can edit /etc/hosts.allow file and enter IP of the host you want to allow.
If your are using some firewall script like rc.firewall check out if its properly configured, I mean the IPtables chains

good luck

since, i think redhat 7.0 , there is no file inetd, but instead , there is a directory /etc/xinetd, which contains the services ( ftp, telnet ....).
to run the telnet or ftp ( not the case for httpd for example) server you must run the xinetd daemon.

why, firewall ? because firewall could block the access to the machine?
so the question remains open

thank for help

To list the tcp ports open for listening,
netstat -tanp

Your firewall may not have any -j LOG rules in it to create messages, so do
chkconfig --list
and see whether ipchains or iptables is set on for levels 2,3,4,5, then either
service ipchains stop ,or
service iptables stop
to remove the firewall while you test.
You can turn the xinetd services on & off with chkconfig as well... eg
chkconfig telnet on
