[srslte-users] can not connect to internet on Jetson TX2

[Ralph A. Schmid, dk5ras]

On my TX2 I had to compile a new kernel, because the sctp stuff was not compiled into it. Was a real PITA for one who never did this. However I have no idea if actual releases maybe already support this.

Seems like your kernel does not like to enable IP forwarding.

What is the output of "cat /proc/sys/net/ipv4/ip_forward"?

I tried 2) sudo tee /proc/sys/net/ipv4/ip_forward 1>/dev/null

It hangs. 

I tried to use “route” or “ping ..” , the machine hangs. Then reboot automatically.

 

Thank you so much!

try to run these commands? ( sorry for not familiar with the script commands)

 

1) sudo -v

2) sudo tee /proc/sys/net/ipv4/ip_forward 1>/dev/null

3) sudo iptables -t nat -A POSTROUTING -o $1 -j MASQUERADE

 

Thank you so much!

So the srsepc_if_masq.sh script itself hangs?

Have you tried running the commands on the script manually to see which one is causing issues?

Dear srsLTE team

I ran srsLTE on Jetson TX2 by using LimeSDR USB as the RF end. A COST UE with a programmable SIM card connected  to the srsLTE.

when running ./srsepc_if_masq.sh to set epc interface to the internet., terminal stopped there . Even though ctrl+c could not stop the script. Of course "route" had no output. ping an Ip address was ok. But ping www.google.com <http://www.google.com>  stopped working.

I can not open the website either.

 

Does anybody have any idea? 

Any help will be appreciated!

 

 

Jane
