Reboot Script for Linksys WAP200 access points

September 15, 2009May 13, 2013Ryan7 Commentsbash, cisco, linksys, reboot

Since the Linksys WAP200 has a tendency to hang and not let any users connect anymore, this little script to reboot an accesspoint (webinterface still works fine). Replace user and password with correct values.

#!/bin/bash

if [[ "$#" == "1" ]]
then
nc -w1 -z $1 443
if [[ "$?" == "0" ]]
then
wget -q -O - --user=foouser --password=foopass --no-check-certificate --post-data='DeviceReboot=1&amp;page=AdminReboot.htm' https://${1}/reboot.cgi &gt;/dev/null
else
echo "Could not connect to https webinterface on ${1}"
fi
else
echo "Usage: $(basename $0) "
fi

#!/bin/bash

if [[ "$#" == "1" ]]

then

nc -w1 -z $1 443

if [[ "$?" == "0" ]]

then

wget -q -O - --user=foouser --password=foopass --no-check-certificate --post-data='DeviceReboot=1&page=AdminReboot.htm' https://${1}/reboot.cgi >/dev/null

else

echo "Could not connect to https webinterface on ${1}"

else

echo "Usage: $(basename $0) "

Cisco kleinigkeiten

Zwei Kleinigkeiten die ich heute beim scripten nachschlagen musste:

– “terminal length 0” lässt das, beim scripten, nervige “– more –” verschwinden

– neben “include” und “exclude” kann man beim pipe | auch “begin” benutzen. z.B. “sh run | b router ospf”

Cisco reverse telnet (AUX -> CON)

March 27, 2008Ryanaux, cisco, con, telnet

Let me jot this down before I forget it again, I’ve looked this up so often 😉
First we hook up the CON port of the borked device with the AUX port of a working router (the normal Cisco console cable with RJ45 connectors on both ends). Then we go to the router and configure it’s AUX port with these settings:

# conf t

# line aux 0

(config-line)# modem InOut

(config-line)# transport preferred all

(config-line)# transport input all

(config-line)# transport output all

(config-line)# stopbits 1

(config-line)# end

The router has to have a loopback address and it must be up (duh). Now we have to find out which port we are going to have to telnet to. Do a show line from the enable mode, the output should look something like this:

Tty Typ Tx/Rx A Modem

0 CTY – –

* 97 AUX 9600/9600 – inout

* 98 VTY – –

Our line is number 97, telnet to the loopback address and port 2000+our line. If our loopback had the IP 192.168.100.200 the command would be telnet 192.168.100.200 2097
