RE: Telnet problem
It is your TCP Wrapper in the target machine. OK check the /etc/hosts.deny on the target machine, if your host machine IP address there, then remove it. Or it could be that the target machine hosts.deny is setup to deny all access and only allow the localhost connection. In that case you will find one line as below: ALL: ALL If thats the case -which is good- then you need to enter the following into the /etc/hosts.allow of the target machine. ALL: 172.20.90.100 this will make the 1st machine (host machine) able to access all tcp services on the target machine. BTW some linux firewalls automatically enter Attacking IP Address to hosts.deny. For example if you have PortSentry installed and if it detects any port scan on any port (that is monitored by it) it will block the IP by adding an entry of that IP to /etc/hosts.deny there by denying tcp access to the services for that particular IP or hostname. You can read more from the man pages and see the links below: http://www.sfu.ca/acs/security/linux/tcp-wrappers.html http://www.linuxtrainers.biz/articles/tcpwrappers.html Regards, Al-Juhani [EMAIL PROTECTED] = Original Message From [EMAIL PROTECTED] = Hello, I am trying to make a telnet connection between two machine running RedHat.

Try changing "LOCAL" to the actual net block. For example, try using: ALL: xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy Where xxx.xxx.xxx.xxx is your network IP and yyy.yyy.yyy.yyy is your netmask.

Re: Telnet Problem
I suppose you could take a basic tutorial on "troubleshooting your network". There is no command as such which will tell you why telnet is not happening. You can go through some of the FAQ's,HOW-TO's at: http://www.redhat.com/mirrors/LDP/ For HOW-TO's: http://www.redhat.com/mirrors/LDP/HOWTO/HOWTO-INDEX/howtos.html Vineeta harmit wrote: I am using IP to ping . What services ,need to be checked .Could you help me by giving the comands for that? Vineeta wrote: There are a couple of things you could check. I don't know whether you have your own nameserver and if you are trying to telnet by hostname and not ip address.Secondly,just because it's pinging to the remote host doesn't mean that the service you are trying to access on the remote m/c is running.you need to verify that. Try from other machines,other network... Perhaps,you could send across the ip address of the machine you are trying to access... maybe,we could help.

Re: Telnet Problem
Something else to check is your /etc/hosts.allow and hosts.deny files. If your /etc/inetd.conf has the proper entries in it, which IIRC it does by default, and you are sure that you did install the telnet-server rpm, then the next place I'd check is the hosts.allow and hosts.deny file. Normally, I have something like 'ALL: LOCAL" in my hosts.allow file, and "ALL: ALL" in the hosts.deny file. Try 'man hosts.allow' for more information on tcp wrappers.

Re: Telnet Problem
Hi, Did you check both hosts files to make sure you don't have any typos? Check hosts.allow and hosts.deny I messed around for awhile one only to discover I had hosts.deny set to deny all and hosts.allow didn't allow the other machine access. Also are you trying login with telnet as root, the default does not allow this. Good Luck Linda hanigan On Sat, 3 Mar 2001, harmit wrote: Hi I am not able to telnet linux6.2 box .

Re: telnet problem
Yes I checked all the files, Everything seems to be ok. Nothing is defined
in that files.
What is inet.d,? you mean inetd.conf, I checked that, it is also seems to
be right..

Re: telnet problem
Are you saying your trying to telnet an online server via a lanned machine or via net access. Also what does /var/log/messages and /var/log/secure say when you attempt this on the telnet server and the online server. Could it be a hosts.allow problem? Usually if it is a hosts.allow entry problem you would see connection refused. Can you give me some more info to go on and I may be able to help you.

Re: Telnet problem
As a side note here, I've got a question related to the telnet/ftp time problems. On my lan at home, when I have my workstation set up on the localnet, with just the ethernet card, the routes look something like: Destination GW Genmask Flags Metric Ref U Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 127.0.0.0 * 255.0.0.0 U 0 0 0 lo default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 When I telnet or ftp to the gateway, it times out for a minute something, then connects. However, if I REMOVE the default route on the workstation, it works instantly. Anyone?
