KDB+ IPC?

Hey Qbies, 
I am trying to connect to my tickerplant from a different machine. I’ve messed around with hopen, and am able to perform queries on tables located on the tickerplant machine.

However, listening to the tickerplant has not worked out thus far. 

I think I’m missing something simple. 

Any help appreciated!

Hi

Could you give an example of the command you’ve used to subscribe to the tickerplant?

Hi,
Did you try to use full name?

h: hopen `:fullname:port;

h “2+2”

Can you ping host and check port?

May be you have firewall or antivirus..

Can you open host/port from the local host?

Can you show the error?

Hey Igor, 
I was able to use hopen.

h:hopen `ipaddress:port – works no problem.

h “select stuff from table” works no problem.

I’m attempting to use the same code that I have currently in use on the server where the tickerplant resides. I have a series of q processes that listen to the tickerplant and perform functions. 

When I run the q processes on my machine I don’t get an error or anything (nothing happens). I have updated the h:open code in the c.q file to reflect the ipaddress of the server machine. 

But it’s clear that it’s not listening to the tickerplant on the server. Not data or errors come through.

ok, in  this case you can run q process in debug mode and check upd, port   and  other functions 
q <yourfile.q> -e 1

also check environment  variables , may be you have special logic on the server
