Re: procServ comminication with phoebus problem

Hello Ewen,

You are messing up two different things: procServ’s telnet port and Channel Access (CA) port. They are independent, not related to each other at all.

Since you are using ‘org.phoebus.pv.ca/auto_addr_list=false’, you probably should use “org.phoebus.pv.ca/addr_list=your-network-broadcast-ip”. Of course, you need to find “your-network-broadcast-ip” by yourself ( it is probably 192.168.238.255). You may need to restart your Phoebus after you re-configure the network settings.

Subject: procServ comminication with phoebus problem

Hi,

   I have a problem when I use procServ .It can works:
[root@localhost iocmyexample]# procServ -n "my-ioc" -L my-ioc.log -P 8888 -i "^D^C" /usr/local/EPICS/iocs/iocBoot/iocmyexample/st.cmd

procServ: spawning daemon process: 18044

[root@localhost iocmyexample]# ps aux | grep procServ

root      18044  0.0  0.0  16928  1268 ?        Ss   22:47   0:00 procServ -n my-ioc -L my-ioc.log -P 8888 -i ^D^C /usr/local/EPICS/iocs/iocBoot/iocmyexample/st.cmd

root      18093  0.0  0.0 112816   972 pts/1    R+   22:47   0:00 grep --color=auto procServ

[root@localhost iocmyexample]# caget ewen:aiExample1

ewen:aiExample1                6

[root@localhost iocmyexample]# caget ewen:aiExample1

ewen:aiExample1                0

[root@localhost iocmyexample]# caget ewen:aiExample1

ewen:aiExample1                4

[root@localhost iocmyexample]#

My phoebus setting.ini is::

org.phoebus.pv.ca/addr_list=192.168.238.134:8888

org.phoebus.pv.ca/auto_addr_list=false

It cannot read the value ewen:aiExample1, but when I close the procServ  and change the addr_list to org.phoebus.pv.ca/addr_list=192.168.238.134:5064 ,it works well.

Here the log:
