Hi!.
When I have to use my X310, executing the command “uhd_usrp_probe” I
obtain the following message:

I receive a lot of warning with the request to run the command:
Please run: sudo sysctl -w net.core.rmem_max=576000.
After that I run twice this command, all the warnings disappear and I
can use the board.
If I switch off my linux box and I restart all, the command
“uhd_usrp_probe” produces the same warnings how reported here.
There is a way to “hard write” in the linux box this configuration
command to avoid every time to check if the board is ready or not?
My linux box is:
Ubuntu 16.04: uname –a :
Linux name-linux-box 4.4.0-103-generic #126-Ubuntu SMP Mon Dec 4
16:23:28 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Thank You.

Look at the man page for sysctl.conf
SYSCTL.CONF(5) File Formats SYSCTL.CONF(5)
NAME
sysctl.conf - sysctl preload/configuration file
DESCRIPTION
sysctl.conf is a simple file containing sysctl values to be read
in and
set by sysctl. The syntax is simply as follows:
# comment
; comment
token = value
Note that blank lines are ignored, and whitespace before and
after a
token or value is ignored, although a value can contain
whitespace
within. Lines which begin with a # or ; are considered
comments and
ignored.
