How can I increase the value of somaxconn?

Question

I can check its value by cat /proc/sys/net/core/somaxconn,

is it OK if I change it simply by echo 1024 > /proc/sys/net/core/somaxconn?

Solution 1

Yes. Alternatively, you can use:

sysctl -w net.core.somaxconn=1024

Add net.core.somaxconn=1024 to /etc/sysctl.conf for it to become permanent (be reapplied after booting).

Solution 2

yes /proc/sys/net/core/somaxconn is writable if you have the permissions to do so.

so both /proc/sys/net/core/somaxconn and /etc/sysctl.conf are persistent?

[Eduardo Ivanec]

@linux_user - no, only modifying /etc/sysctl.conf is persistent. /proc is not a "real" filesystem, only a filesystem interface to the kernel.

You would have to modify /etc/sysctl.conf as root to make it persistent. /proc is not a real file system
