I have an issue where I can't seem to get it working over the network I have a hackrf and a Pi2 as the server and several linux desktops that can't see it at all. SoapyServer runs fine on localhost though. For example on the server I can start the server:
`pi@sdr:~ $ sudo SoapySDRServer --bind 192.168.10.10
######################################################

Soapy Server -- Use any Soapy SDR remotely

######################################################

Server version: 0.5.2-gd11da72a
Server UUID: 44948858-c55b-15a1-8567-01cc007f0101
Launching the server... tcp://[::]:55132

SoapyServerListener::close()
SoapyServerListener::accept([::ffff:192.168.10.10]:34650)
SoapyServerListener::close()
`

I can access the SoapyServer from the server pi machine only (ie it's own IP address - 192.168.10.10):

`pi@sdr:~ $ SoapySDRUtil --find="remote=tcp://localhost:55132, driver=remote"
######################################################

remote:driver = hackrf
serial = 0000000000000000a06063c82b1e5313

`

Trying from any other machine results in nothing:

`me@linux-desktop2:~$ SoapySDRUtil --find="remote=tcp://192.168.10.10:55132, driver=remote"

I have rebuilt the pi from scratch, and tested the network with a usb RTL2832U rtl-tcp server and gqrx which works fine, but I want to get my hackrf to work, so I 'm trying Soapy server. Any ideas why I can't see this from any clients on the same LAN?

Thanks

Do I need to install the hackrf driver on the client? I was hoping it just ports though to gqrx like the rtl server did, or I am missing something?

seems to be listening, just can't connect...

Here is another client with the Soapyhackrf installed, but still can't connect to the server:

Got it to work!

I needed to install SoapyRemote on the client as well.

Now i have:

Available factories... hackrf, remote

Done!

Hello,

In my case, I also had to install soapyRemote package on my client (notebook with manjaro), and only then SoapySDRUtil started recognizing remote devices. Before, it just returned "no devices". The lack of any verbose error message made this whole thing mildly confusing.

I'd like to edit an wiki page to explicitly mention that soapyRemote is required on both server and client but before I do, I'd like to ensure that's not just an edge case, specific for the package in arch repos.

Maybe some of the implementation details give it away, but yes, the package needs to be installed on both ends
