Re: caget from win failed when xspress3

["Yin, Zhijian via Tech-talk" <tech-talk at aps.anl.gov>]

Hi, Lynn,

We've have similar problem with xspress3 in the past: the vendor's PC (and ioc) was limiting ca traffic to localhost. 

I don't know your set up, but you may want to check /etc/profile.d/epics.sh, if there is a line like below

export EPICS_CAS_INTF_ADDR_LIST=localhost

comment it out

Hi Lynn,

This sounds like a firewall problem.  You said "firewall was closed".  What firewall are you referring to?  It could be either the Linux firewall or the Windows firewall.  To begin with I suggest completely disabling both firewalls.  If the firewall is the problem then re-enable them with rules to allow EPICS traffic to pass.

Subject: caget from win failed when xspress3

 

Hi,

   I met an question about caget.

  The situatuion was like  https://epics.anl.gov/tech-talk/2019/msg01836.php. I try a lot, but i still failed.

 

   I have 2 pc, first one was xspress Linux pc, which provided by the manufacturer;  the second was a windows pc.

   The linux pc( xspress pc ): there are two NIC and one wireless, one NIC is 192.168.0.2 for device1 , another NIC is 192.168.2.31(for epics)

   The windows pc: one wireless and one NIC:192.168.2.30( 255.255.255.0, gateway:192.168.2.1 and no gateway neither could worke )

   192.168.2.30 and 192.168.2.31 was in same router, just has the two cables in the router.

   

    Device connection was good, firewall was closed, IOC was good and started, pv name was right and i could caget from the linux pc itself.

    I set both pc the environment to YES or NO/localhost or NO/192.168.2.31or NO/192.168.2.255. None could work.    

    I don't think it was a big question, but i do failed. After so many failed, maybe it's the question about network setting, so i put the setting bellow.

 

These thing has lagued me.

Could someone give me some advice.
