How to verify on client side

Submitted by Gohper on #1

Hi Michael,
I am new to VirtualHere after struggling with usbip on a Rasberry for while.

I have started the server on the RasPi and the client i running as a deamon on the client.
I can USE my RasPi device on the client. So far so good.
BUT, how can I verify that the device "exists" on the client computer?
I have tried lsusb and looked in the /dev/, but nothing...

If this works, the Mrs will be very happy (I will probably recieve a gold star from here).
The client is a server that is located in the sleeping room, starts at 5.30 (her problem) and shuts down at 22.00 (my problem) :o)
To this client a weatherstation is connected and it would be very nice to just have the RasPi there.

Best Regards

Gohper

lsusb should show the device. I am assuming that it is a serial to usb device for the weather station. That would appear as a /dev/ttyUSB0 or similar on the client. Remember that you cannot run the client as a service with a free server, you need to purchase the server. Perhaps this is the problem?

For the moment it is a security card device, just as a test, some kind of Wasco Digipass.

Ok, it could be the problem, but when I run it I can list and "USE" it, maybe the license blocking is later on, ie towrds the usb.

I will try to figure out how to run it as non deamon, just to see.

Thanks!

Hmm, how to use the console client not as a daemon?

There are some parts missing in the documentation ;)
That is the console client config file option, I guess that i can run it like:
./vhclienti386 --config=/home/virtHere/myconfigfile

But what is the format of the config file?

I can say that, even if there is documentation missing, it looks more promising than the ordinary usbip.
And if this works, I will purchase a server license, that's for sure!

open two terminal sessions.

In the first one run "sudo ./vhclienti386"
In the second control it like so:

./vhclienti386 -t "LIST"

then

./vhclienti386 -t "USE,4262432142"

etc.

GREAT!
Thank you Michael!
But I did:
./vhclienti386&
./vhclienti386 -t "USE,4262432142"

I will try with the weather station when I arrive home from work, ssh can not switch the cable yet :o)!
But so far like a charm!

Ahhh, like a dream!
The weather station is connected and the pywws can fetch data from it!
Some minor fixing and a license, then the server can move down to the basement!

This is awesome!

But when they have been running for 2-3 hours a message appear:
"socket AF_INET: No file descriptors available"
It still works, but what does it mean?

UDP port 5353 is used to lookup servers on the network. Seems like there might be a leak in that version of the client... ill take a look...

Maybe this can help you, the port usage is increased with two every 30 seconds.

#13

Does this have somthing to do with this?
AutoRefreshLookupPeriod=30

BTW, It works very nice, so I want to purchase a license, but under point 3 there is something that I should paste.
How can I get this from the shell only client?

#14

Decreasing the value
AutoRefreshLookupPeriod=10

gives a decrease of used ports by 2 every 10 seconds, maybe it will give you a hint were to look...

Setting it to zero was not a good idea!

It is runnable with 3600 as value (1hour, I guess).

As the weather station is restarted to clear the collected data in the memory once every 24h the client can be restarted at the same time.
For now at least.

Now I have some scripting to do....

Gohper, i have updated the client to 2.6.3. the socket leak is fixed in this version as well i added the licensing details via IPC

1. Please download again from my website
2. Run the client in the background or in another shell sudo ./vhclienti386
2. To get the serial number details: ./vhclienti386 -t "LIST LICENSES"
3. Copy the returned line into the payment page on my website, it will send you a key via email after payment
4. To enter the license: ./vhclienti386 -t "LICENSE SERVER,key"Where key is replaced with the key in the email
5. To confirm type : ./vhclienti386 -t "LIST LICENSES" and it should now show unlimited
