[dpdk-dev] Any ideas how to stop DPDK from banning me from the box.

[Dmitry Vyal]

Greetings!

I've been playing with dpdk on my desktop for some time and decided to 
finally test in on a server. It has a plenty of nics:

I connect to the server using ssh through one of gigabit ports. The 
problem is that no matter which cards I blacklist with -b option then 
starting my dpdk application it takes away all the interfaces from the 
kernel and later returns blacklisted ones. This disrupts my ssh session 
and I can no longer connect to the server.

Any ideas how to overcome this?

Best regards,
Dmitry Vyal.
