Hey Han,

 

Tried to switch the localhost with the ip but still didn’t have any success.  I did also try to switch back that server.xml port to 8080 just to try but that didn’t help either.

 

<Connector connectionTimeout="20000" port="17665" protocol="HTTP/1.1" redirectPort="8443"/>

 

I will double check but caget,camonitor, caput seem to work fine from the PC to the same PC that has the archiver from what I remember.  I made sure the env variables are set on the client PC correctly.

Hi Adam,

 

Please change all localhost to your IP address, which you are using. And let me know what it will be.

 

Best,

Han

Hi Adam,

 

Can you share your appliances.xml file? I want to see how you define them.

 

Best,

Han

Hi Andrew,

 

 

Sorry for the confusion on the ips, the internal network we run this on does route properly. I am able to ping the corresponding computers and also we have another web server running that I am able get to.  I don’t think it’s the web browser or Phoebus, since I have tried just doing direct queries through python and not getting a response either.  I asked our IT again and there shouldn’t be anything blocking.

I am trying to figure out why I cannot access the front end interface of the archiver (192.168.3.50:17665/mgmt/ui/index.html) from another subnet.  Locally it works perfectly fine, able to archive PVs and retrieve with Phoebus for example or even using python.  When I try to get the web page to serve up on another PC that is not on the same subnet 192.168.2.25(PC) and 192.168.3.50(Archiver) for example it seems like the request gets stuck.  Some possible debugging has led to the JS not being loaded properly on the web browsers but I have looked for anything that would block on the network and cant seem to find any issue.

 

The IP addresses that you are using (192.168.*.*) are in the Private IP range, and are often not routable (at least when it comes to transit over the public internet). Do you know for sure that your routers are properly configured to pass packets between these subnets? Can you ping between them (both ways) and make some kind of a TCP connection (e.g. ssh or telnet) with devices in the other subnet?

 

I know nothing about the internals of the Archiver Appliance, tomcat, or the Java network stack, but it’s conceivable that something there (or even in a firewall) might also be preventing packets from the other private network from being delivered or sent.

 

Just an idea, I might be completely wrong though.
