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?

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).

so both `/proc/sys/net/core/somaxconn` and `/etc/sysctl.conf` are persistent? – linux_user May 20 '11 at 01:17

@linux_user - no, only modifying `/etc/sysctl.conf` is persistent. `/proc` is not a "real" filesystem, only a filesystem interface to the kernel. – Eduardo Ivanec May 20 '11 at 04:11

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

You would have to modify /etc/sysctl.conf as root to make it persistent. /proc is not a real file system – Ganesh Krishnan Mar 16 '15 at 00:53
