Hi Mark, Thanks for your e-mail. It looks like the issue is with the port mapper or firewall rules. I am able to access gpib gateways from another subnet so it looks like that the connection is not EPICS 7 nor asyn related. I am sorry for the

Hi Mark,
Thanks for your e-mail. It looks like the issue is with the port mapper or firewall rules. I am able to access gpib gateways from another subnet so it looks like that the connection is not EPICS 7 nor asyn related. I am sorry for the false alert.
Best Regards Mirek
Hi Mirek,
I have been running a VXI11 device with base 7.0.7 and recent versions of asyn on Centos7 and CentOS 9 with no problems. I am currently using the master branch (a bit beyond 4-44-2). But I think R4-42 should work fine.
This is the command in my startup script:
vxi11Configure("serial2", "164.54.160.16", 0, 0, "gpib0", 0, 0)
Your error is happening because clnttcp_create is failing:
https://github.com/epics-modules/asyn/blob/a94a78987a99b1c36bbd641a67341069dc5d627e/asyn/vxi11/drvVxi11.c#L930
You may need to add some debugging to see why that call is failing.

Hi All, We are migrating in ALS from Centos7 to RockyLinux8 and from EPICS 3 to EPICS 7. 0. 7 . One of our ioc which runs on Centos 7 EPICS 3. 15. 4 asyn4-30 runs
fine and can access the GPIB devices via gpib gateways. The same ioc when converted

Hi All,
We are migrating in ALS from Centos7 to RockyLinux8 and from EPICS 3 to EPICS 7.0.7 .
One of our ioc which runs on Centos 7 EPICS 3.15.4 asyn4-30 runs fine and can access the GPIB devices via gpib gateways.
The same ioc when converted to EPICS 7.0.7 with asyn-R4-42 on RockyLinux 8
reports the problem as below:
vxi11Configure ("gpibport01","gpib01",0,0.0,"gpib0",0,0)
dbLoadRecords("db/gpibport01.db")
iocInit()

I compiled the same code (with EPICS 7.0.7 with asyn-R4-42) on centos7 and ran it on Centos7 and the error messages are identical.
Would that be a problem with EPICS 7.0.7 and new asyn-R4-42 vs EPICS 3.15.4 asyn4-30 ?
