Unable to telnet to newly upgraded OpenVMS 7.3-1 server

[Bjarne Steen Hansen]

Hi !

We have recently upgraded to OpenVMS 7.3-1 and TCP/IP 5.3-18.
We are now unable to telnet to the server, even locally to 127.0.0.1.
THe funny thing is, at we can't SET HOST (DECnet) either.

Any ideas ???

Hello

with
$ana/sys
sh lan

do you see the protocols Decnet and Tcpip ?
Do you use Decnet over Tcpip ? (that could explains why, if Tcpip does not work, Decnet too does not work)

What does

$ tcpip sh ver
shows ?
Do you have Tcpip 5.3 or tcpip 5.3 Eco 2 (which is the latest ?)

$ sh lo tcpip*
does show a logical with the state of Tcpip (started or something else)
What do you have ?

regards

Gerard

Is port 23 enabled?
Is Telnet enabled and started?

[Karl Rohwedder]

Did you change something else,may be add an additional controller, so that the names have changed?
Check TCPIP SHO INTERFACE, if an interface is
defined. Check MC LANCP SHO DEV ... /CHA.
May be just rerun NET$CONFIGURE and TCPIP$CONFIG.

Hi Bjarne,
there are some thinks to check.
1)Does your NIC working?
-Check interface:
$ TCPIP
TCPIP>if config -a
after this command you see interface characteristic for TCPIP; you must see at least 3 interface, TN0, LO0 and NIC interface (example WE0).
-Check TCP/IP connection:
TCPIP>ping 127.0.0.1
TCPIP>ping
After this command you could check your network working fine.

2) Is service Telnet enabled and ready?
-Check for enabled
TCPIP>SH SERV TELNET/FULL
You must see enabled state, limit > zero (at least 50) and other info.
-Check if ready
TCPIP>SH DEV
You must see one dev BGn:, type STREAM, local port 23, service TELNET, remote hist 0.0.0.0

For Decnet you have to declare if you are using phase IV or ISO.

After your post we can send furthermore help.

Hi everybody !

Thanks for prompt replys

The funny thing about this problem is, that the network is running.

We can do FTP's to/from the server. We can even do a DECnet directory to the host in the form "$ DIR HOST::".

We haven't installed the ECO 2, but I will try this today and get back to you.

Hi,

Can you start again from scratch. Rename all your TCPIP configuration files, and then reconfigure your TCPIP and its services. Then restart TCPIP .

$rename sys$system:tcpip$*.dat sys$system:tcpip$*.dat_OLD /log
$@sys$manager:tcpip$config...( reconfigure your complete TCPIP settings ).
$@sys$startup:tcpip$shutdown
$@sys$startup:tcpip$startup

Optionally you can reboot your system too. This process may is lengthy, but it should give results.

Thanks & regards,
Lokesh

do you get a response to telnet and if so what is it? If you do parhaps there is something in the system wide login thats causing a problem for interactive remote logins?

[Martin P.J. Zinser]

Hello Bjarne,

what does tcpip show service telnet/full

give?

Is the service enabled?

Greetings, Martin

Hello Bjarne,
you checked network is working.

Now you must check telnet service; do you executed command I hint you?
-Check for enabled
TCPIP>SH SERV TELNET/FULL
You must see enabled state, limit > zero (at least 50), addr must be 0.0.0.0 and other info.
-Check if ready
TCPIP>SH DEV
You must see one dev BGn:, type STREAM, local port 23, service TELNET, remote host 0.0.0.0
-Check if requests have reach your host
TCPIP>SH PROT TCP
Look for connection request, if 0 no connection has reach your host.
