Hi Ana, When you ssh to the device you are implicitly using port 22.
You don’t want to use port 5064, that is for EPICS TCP messages, not for communicating with the device. How does the vendor describe how to communicate with the device? Only with ssh? Or do they support simple TCP messages using another port? If ssh then that would require
your driver to implement the ssh protocol to talk to it on port 22, which would not be trivial I think. When you ssh into the device what types of things can you do? Mark From: [email protected] [mailto:[email protected]]
On Behalf Of Ana Malagon Hi, I'm trying to make an IOC for a digitizer, the
redpitaya. I've assigned it a static IP address and can successfully ssh to it, doing However, there doesn't seem to be a specific port I should use in connecting to it - as least I see no mention of it in the documentation. I've tried using the "default" port numbers 5064,5065 in my st.cmd file, but both options give the Can't connect to 10.95.101.75:5064: No route to host L0 -1 autoConnect could not connect error message. I also get this warning cas warning: Configured TCP port was unavailable. cas warning: Using dynamically assigned TCP port 33122, cas warning: but now two or more servers share the same UDP port. cas warning: Depending on your IP kernel this server may not be cas warning: reachable with UDP unicast (a host's IP in EPICS_CA_ADDR_LIST) but I've seen this with other IOCs for other devices, and those IOCs still work, so I'm assuming these warnings are not the fundamental issue. Does anyone know what other ports I should try or should I instead try to reconfigure the redpitaya and assign it a port as well? Thanks, Ana Malagon |
