Router - TG582N - Config Files

There are several files used to store the configuration of the TG582n. These can be seen by FTPing to the router

ftp> dir

The file named user.ini is probably the most interesting. The files isp.def and user.tpl between them appear to provide the factory default config, with the ISP specific config in isp.def.

From here on, it's the user.ini file we play with.

One can download the file contents to a local computer by a number of means - e.g. using the web interface, or FTP.

Storing the config in CVS

Your author is big in Software Configuration Management, and likes to store important config files in CVS. CVS can use keyword expansion to store version information etc. in the file. I wanted a way to store this information in the config file on the router. What I needed was a field which allows a large enough text string, and finally I found one - under firewall levels!

:firewall level add name=DummyEntry index=4 readonly=enabled udptrackmode=strict service=enabled proxy=enabled text="\\$Id$"

Now when I commit changes, and then restore the configuration file to the TG582n, the text is replaced by (e.g.):

\$Id: user.ini,v 1.14 2015/08/30 16:20:31 adsb Exp $

Needless to say, don't use this firewall level unless it's configured properly!

Managing multiple config files on the router

The command

:config list

shows all the user.ini type files on the router. If you want to store a copy of a temporary configuration, you can do for example:

:config save filename 30Aug15.ini

:config list
Configurations file(s): 
  30Aug15.ini
  user.ini

The matching command :config load is used to load from a configuration file - it's perhaps worthwhile doing :config menu and selecting load to see the options available (whether to flush the existing config, whether to load IP settings, etc.).

The command :config delete filename=<filename> can be used to delete a no longer required config file.
