modesmixer2 not working with sbs-1er under linux

[gwarne64]

I have a sbs-1er that works using basestation and modesmixer2 under windows 7 but I cannot get it to work under linux.
I am using the modesmixer2_x86_64_20150307.tgz version but it is the same with the 20141121 version. I am running Centos 7 on my linux system.
It appears that the code sends 2 short identical login messages to the sbs-1er then waits for 2 responses. The 2 responses appear to be coming back in 1 packet so it sits in an infinite loop waiting for the 2nd message.
Under windows the response to the first message comes back before the second message is sent, so everything is happy and the second response follows the second message and so the last message is sent starting the sbs-1er sending out its data.
I have wireshark dumps and strace outputs which show this action.
Please let me know if there is a fix for this.
I will try under a different linux distro on another platform but I do want to get it working under Centos 7.

Thanks

Hello sergsero

Thanks for your help
My SBS-1ER connection settings and firmware are the same as yours but I continue to have problems on more platforms.

Under Windows it connects most of the time but sometimes requires a couple of tries.

modesmixer2 running on the netbook and raspberry pi can both connect to the modesmixer2 running under windows if I add a outServer with sbs10001 format.


My sbs1-er settings are attached

Hello gwarne64,
   
Although I can't reproduce this situation, I will try to find out what could be the cause of the problem.

Thanks,

Hello sergsero

Thanks again.
I have a tcpdump and strace dump of the connection attempt.
They are attached.

Thanks Gwarne64
