telnet problem
I have 2 machines, machine A and machine B. From machine A, I'm able to ping machine B using hostname and ip address but not able to telnet to machine B with the error " telnet : Unable to connect to remote hosts: Connection refused" . In machine B, I'm able to nslookup machine B and able to telnet to machine A. I've checked the /etc/hosts, /var/yp/secureservers, /var/adm/inetd.sec, /etc/resolv.conf, /etc/rc.config.d/namesvrs and nfsconf files but seems like everything is ok. I even plug out the network cable and try to ping machine B to make sure the ip is unique and confirm it is an unique ip. Any idea?

Re: telnet problem
do you have a line like this
telnet stream tcp nowait root /usr/lbin/telnetd telnetd
in /etc/inetd.conf of machine B ?
after inserting the line you have to reread the configfile with "inetd -c"

Re: telnet problem
How are the machines placed.
Are the machines in the LAN.
Is there any firewall in between.
Is your port 25 opened for use?

Re: telnet problem
Make sure you have entries for telnetd in the inetd.conf file.
how are the machines placed?Are they in the local LAN
Is the port 23 open.
DO you have any files like /etc/hosts.allow and /etc/hosts.deny

Re: telnet problem
Is inetd running at all ?
If so do you have a /etc/hosts.allow file ?
If so is the machine A in there on machine B ?

Re: telnet problem
I do not have any /etc/hosts.allow or hosts.deny file in machine B. Anyway, when I reboot the machine B, I 'm able to telnet to this machine. I don't know why but this resolve my problem. Thanks to everyone who give some so useful information. Thanks once again.
Rgds,
Chin Soon

Re: telnet problem
I guess your inetd was not running anymore.
Check your /var/adm/syslog/syslog.log file for any clues regarding telnet or inet.
