cannot do a telnet from my pc

Hi all,

I can telnet from one rx6600 server (host01) running HP-UX 11.23 to another rx6600 server running HP-UX 11.23 (host02) also. But when I try to telnet from my PC, I can't telnet directly to host02 but I can telnet directly to host01. Please help.

Thanks!

Hi Misa,

Most Probably there is some network related config on the host host02, some privacy in the settings and network access, like you can telnet to host02 only from the network that host01 belongs or something.

Please get in touch with the network administrator for more clarity on the network Securities.

thanks sujit. the two hosts are on the same network segment and there are no security configurations on that network.

Hi,

Check /var/adm/inetd.sec file on host02. Telnet service might have restricted with specific ip or network range.

The inetd.sec file is still in default. No changes were made to this file.

Addendum: I can't also do a ping from my PC to host02.

Re: cannot do a telnet from my pc

Hi,

If ping is not working then we may need to look into network part..

PC and host02 are on the same network? If no, have you configured gateway on PC?

Are there any firewall in between the pc and host02?

PC and host02 are on the same network? >> Yes.

If no, have you configured gateway on PC?

Are there any firewall in between the pc and host02? >> No.

The problem is that the PCs in this network experience the same problem. They can ping/telnet host01 but can't do the same for host02. Verified all network-related files and paramters and all seems ok.

Re: cannot do a telnet from my pc

Hi,

If it is in same network atleast we should be able to ping unless otherwise we have disabled ICMP protocal in router.

Are you able to ping host02 from host01?

Could you provide the netstat -in and netstat -i outputs from host02 and ipconfig output from pc?
Best wishes,

Ganesh.

Even if they are on same network, there is somewhere the breakage occuring it seems.

Can you do a tracert & then you can find where your packets are getting dropped off.
