Is tryed to modifiy the runvdr vdr startup line with the option -p 2001 but

Is vdradmin running on the same machine as VDR?

If so, can you do "telnet localhost 2001" and get immediately
'connection refused' or does it simply time out?

I'm thinking SuSE's firewall is in place, and blocking access to
'strange' ports.

I have no actual SuSE knowledge of how its firewall is configured, but I
can at least talk more generically :)

Check the output of 'dmesg' for firewall logs - you should see the
connection being DENY'd ...

Yes.

I got this:

VDR:~ # telnet localhost 2001
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

I'm thinking SuSE's firewall is in place, and blocking access to
'strange' ports.
I thinks it works, see above.
I got the following messages in the /var/log/messages

Jun 14 14:23:54 VDR vdr[973]: connect from 127.0.0.1, port 32897 - accepted
Jun 14 14:25:30 VDR vdr[973]: closing SVDRP connection
Jun 14 14:28:20 VDR vdr[973]: connect from 192.168.32.14, port 32898 -
DENIED

It seems that the connection from the 192.168.32.14 address (the address of
my VDR) is blocked. Why?
How can i fix this?

Gosh, IPv6 - how novel to see it anywhere but geek testing zones..

That's quite easy, simply add the 192.168 IP address into
/video/svdrphosts.conf - you may need to restart VDR...

Make sure your svdrphosts.conf is in the right directory and try to
connect your vdr via "telnet" (telnet localhost 2001).

telnet localhost 2001 works, but telnet 192.168.32.14 2001 (address of my

Maybe this is a Firewall problem..... But can i fix this?

telnet localhost 2001 works, but telnet 192.168.32.14 2001 (address of my

that is the problem, you must configure vdradmin, to use
127.0.0.1 and not the lan ip, which is not in your
svdrphosts.conf, and thus gest rejected.
so 127.0.0.1 is not equal to your lan ip.

please provide the info which host your vdradmin tries to connect.

Just look into the svdrphosts.conf:

#
# svdrphosts This file describes a number of host addresses that
# are allowed to connect to the SVDRP port of the Video
# Disk Recorder (VDR) running on this system.
# Syntax:
#
# IP-Address[/Netmask]
