Experimental Physics and Industrial Control System
Hi Adam,
if you have nmap installed on the client PC you can check if the archiver port
is accessible from the client with:
nmap -Pn -p 17600-17700 <archiver IP>
You might have to ask someone with root acces to the PC to issue this
comnmand.
If it shows the port 17665 it will tell you wether it is open, closed or
filtered. Normaly all routers block trafic between different subnets. I gues
only the ssh and ca-1/2 ports once got opened by your IT. If nmap shows the
port as filtered, you have to ask your IT to open the port on the firewal/
router between the subnets. If it is shown as closed, then there is a firewall
on the archiver server which blocks it.
Are you shure you contact the archiver server with caget? You can ask for info
about a PV with cainfo:
cainfo -s 5 <PV name>
It will tell you from where it gets the PV. There might be a gateway server
running somewhere that gives you access to the PV's from one of the subnets
(PC?). Depending in which your IOC's are running this will hand over the PV's
from one to the other subnet by being connected to both. Yoiu can also check
in the archiver from wher it gets the PV's. Just go to the reporst page and
click on details of one of teh PV's it recently archived.
Regards,
Jörn
