Network doesn't work after change network buffers via System ‣ Tunables

[Zeiu]

I've set
net.inet.tcp.sendspace
net.inet.tcp.recvspace
via System ‣ Tunables.

service nginx restart results nginx socket() failed (55 no buffer space available)
Networking not working.

Console is available. How I can change Tunables via console ?

The solution:
Via terminal:

sysctl net.inet.tcp.sendspace=1048576
sysctl net.inet.tcp.recvspace=1048576

service nginx restart
service django restart

Then change System ‣ Tunables.

Any particular reason why you're setting those values?

service nginx restart results nginx socket() failed (55 no buffer space available)
Networking not working.

You're out of memory.

By increasing net.inet.tcp.sendspace or recvspace you're gaining more buffers at the expense of using more RAM.

Please provide more details about your hardware and FreeNAS version.

This solve the problem.

I install openvpn on separate jail. Ping to dest = 70 ms, iperf show 1Mbit/s. I change buffer sizes to increase vpn speed.
