RE: hostname - Daniel - 14.05.2020

Try this

Code:
------------------------------------

require('uci')

uci.set("system.@system[0].hostname=name63characters")

uci.commit('system')

--------------------------------------

What Daniel posted will work but you will have to reboot for hostname to change. You should also write to hostname file in order to change it right away:

Code:
io.writefile('/proc/sys/kernel/hostname', 'myhostname')

RE: hostname - Daniel - 14.05.2020

I tried it and it worked. Your browser cache?

RE: hostname - admin - 14.05.2020

You need to run both code pieces to set both permanent and current hostname:

Code:
hostname = 'myhostname'

require('uci')

uci.set("system.@system[0].hostname=" .. hostname)

uci.commit('system')

io.writefile('/proc/sys/kernel/hostname', hostname)
