Bingo! The attached script is *much* easier than configuring it by hand. 

Rich

#!/bin/sh
# Install and configure the various bits of the
# CeroWrt router for my preferred setup. 
# 10 Feb 2012 -reb

# ssh root@172.30.42.1
# cd /tmp
# cp > config.sh 
# [paste in the contents of this file, then hit ^D]
# sh config.sh
# Presto!

opkg update               # retrieve updated packages
opkg install snmpd fprobe # install snmpd & fprobe
/etc/init.d/snmpd start   # default snmpd config uses 'public' 
/etc/init.d/snmpd enable  # community string for SNMPv1 & SNMPv2c

# Start fprobe now to send netflow records to local netflow 
#   collector at 192.168.2.13 (I use http://intermapper.com) 
fprobe -i ge00 -f ip -d 15 -e 60 192.168.2.13:2055

# Also edit /etc/rc.local to add the same command 
#   so that it will start after next reboot

[Cerowrt-devel] Scripting CeroWrt config

[Richard Brown]

Folks,

I make a number of changes to the router each time I install new firmware. Specifically:

- I install the snmpd and fprobe packages
- I start and enable snmpd
- I configure fprobe to send data to my InterMapper server for monitoring, and add that command to the startup script
- At some point, I may want to change from 172.30.42.x addresses to my "normal" network address range (192.168.2.x).

What's the best way to script this? I'm quite content to paste in a set of commands over ssh, but wonder if there's another way... (Would save/restore do all this?)

Thanks!

Rich

I have a similar need to script things better. The uci interface can
be quite cool.
I would suggest playing with that.

example:

uci show network

There is decent doc on that on the openwrt web site.

#!/bin/sh

opkg update
opkg install snmpd fprobe
sed -i s/172.30.42/192.168.2/g /etc/config/* /etc/babeld.conf (etc -
the full string is on the wiki)

# etc, etc

# and wip for me...
opkg install ipv6policy
net=`generate-rfc4193-addr se00`
parse_network_somehow
get a string of useful networks
uci set network.se00.ip6addr=whatever/64
uci set network.sw00.ip6addr=whatever/64
stick in dns somehow

etc. the ash shell is quite limited so I'd suggest developing your
script on the box.

I'm not, and I agree, this gets very tedious after a while.
I'm very glad I use a routing protocol, because keeping
bloatlab #1 operational without it is nearly impossible.

(as it is, I reflash one box, wait for it to appear anew,
 change everything, reboot it, do another one)

and for all that I've 'lost' 2 of the 8 boxes on that network
(in california) and don't know which ones they are!!

save/restore is unlikely to be a good idea at this point. Too much
stuff changing.

What I do for my much more complex configurations (includes ipv6
and I'd like very much to make it more generic)

i snarf a copy of the default config via scp to my main machine
check all that in git
make the 'perfect' configuration
check all those changes into git

build a new box
snarf it
do diffs...


I'm also working on a generic set of testbed tools for
creating ipv6 ula addresses and getting them into dns.
