hi, how can i write a hostname by script?

io.writefile...

[Daniel]

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')

[pepe]

Try this

Code:

------------------------------------
require('uci')
uci.set("system.@system[0].hostname=name63characters")
uci.commit('system')
--------------------------------------

Thank but does not work, maybe it's also me

worked but the old name is adopted after a restart

I tried it and it worked. Your browser cache?

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)

[pepe]

Try this

Code:

------------------------------------
require('uci')
uci.set("system.@system[0].hostname=name63characters")
uci.commit('system')
--------------------------------------

sorry it works! thanks forgot a sign...
after the restart it will be kept
