ShutOff networking

Scott McDade — Thu, 08 Apr 2010 23:16:21 GMT

Hello:

I am working with Red Hat 5.3 and would like to boot my workstation up without networking as it is configured for a network that I am not currently on. I would like to simply boot up without networking support and keep the netconf files in tact for when I want to boot back onto the network. Is there an easy way to accomplish this at boot time???

hi,

normally you could disconnect the cable from NIC, another way is to disable network services .

/sbin/chkconfig --list |grep network
error reading info for service vxsmfd: No such file or directory
network 0:off 1:off 2:on 3:on 4:on 5:on 6:off

syntax :

chkconfig [--level ]

/sbin/chkconfig --level 2345 network off

Not sure it will work (I've never tried this), but you could try disabling the network service:

chkconfig network off

This will remove links to /etc/init.d/network script from /etc/rc[n].d/ directories. In case you later want networking back:

chkconfig network on

Maybe not enough information on what exactly you are trying to do or accomplish.

If you boot the system up not connected to a network, it may spew out a few errors but it will boot and be functional.

When you are connected back on the network and boot, it should still have the same settings.

If you don't need the GUI, you could boot into init level 2 when not connected to a network
