Hello I have a problem with static DNS.
I am running ROS 2.9.43 on a dedicated AMD based PC.
I have in my internal network a Linux Debian mailserver ( Postfix ) and I wish my clients connect to it with it's name.
I had put a static DNS entry, this is the output:
[alex@badde1_pc] ip dns static> pr
Flags: D - dynamic
# NAME ADDRESS TTL
0 mailserv 10.5.50.252 1d
1 dnsbadde 10.5.50.1 1d
so my clients should insert MAILSERV as the SMTP out, buth this is not functioning.
If I try to ping MAILSERV it fails
The NSLOOKUP command gives this output:
SERVER: DNSBADDE
ADDRESS: 10.5.50.1
NAME: MAILSERV
ADDRESS: 10.5.50.252
So it seems that NSLOOKUP correctly finds the name-address association; but http or SMTP not.
I tryed also a: telnet mailserv
no success also with this command.
My DNS settings are:
[alex@badde1_pc] ip dns> pr
primary-dns: 62.211.69.150
secondary-dns: 0.0.0.0
allow-remote-requests: yes
cache-size: 2048KiB
cache-max-ttl: 1w
cache-used: 1368KiB
Please has someone some suggestion?
Do I missed something in the configuration?
Many thanks for your help
Regards
Alessandro
