Installation Procedures

  • The default lan ip address for wrtsl54gs is 192.168.1.1.
  • Download 23sp2 for WRTSL54GS.
  • Browse Linksys web server.
  • Upgrade the default linksys firmware using the standard version, dd-wrt.v23_wrtsl54gs.bin.
    • There is no need to use the mini-generic one as stated in the hwsupport.txt file.

Turn on SSHd

Go to web interface (default user in v23sp2 is root, password admin), by default at 192.168.1.1... then go to Administration->Services and turn on Secure Shell -> SSHd and Password Login.

Turn on JFFS2

SSH to your WRTSL45GS and run:

nvram set jffs_mounted=1
nvram set enable_jffs2=1
nvram set sys_enable_jffs2=1
nvram set clean_jffs2=1
nvram set sys_clean_jffs2=1
nvram commit
reboot

This reboot takes a while, be patient and don't power the unit off.

Add more packages

To get USB working, install these packages:

ipkg update
ipkg install kmod-usb-uhci
ipkg install kmod-usb-core
ipkg install kmod-usb2
ipkg install kmod-usb-storage
ipkg install hdparm
ipkg install kmod-vfat
ipkg install kmod-ext2
ipkg install kmod-ext3

Then you need to load the modules:

insmod /jffs/lib/modules/2.4.30/usbcore.o
insmod /jffs/lib/modules/2.4.30/ehci-hcd.o
insmod /jffs/lib/modules/2.4.30/scsi_mod.o
insmod /jffs/lib/modules/2.4.30/usb-storage.o
insmod /jffs/lib/modules/2.4.30/sd_mod.o

Modules won't stay loaded across reboots - see USB howto for more: USB wiki page. Basically, you want to make your own startup script in /jffs/etc/config. Make sure it ends in .startup, like myscript.startup.

My script:

#!/bin/sh
insmod /jffs/lib/modules/2.4.30/usbcore.o
insmod /jffs/lib/modules/2.4.30/ehci-hcd.o
insmod /jffs/lib/modules/2.4.30/scsi_mod.o
insmod /jffs/lib/modules/2.4.30/usb-storage.o
insmod /jffs/lib/modules/2.4.30/sd_mod.o
insmod /jffs/lib/modules/2.4.30/fat.o
insmod /jffs/lib/modules/2.4.30/vfat.o
insmod /jffs/lib/modules/2.4.30/ext2.o
insmod /jffs/lib/modules/2.4.30/ext3.o
sleep 2

mount /dev/scsi/host0/bus0/target0/lun0/part1 /mnt
mount /dev/scsi/host0/bus0/target0/lun0/part2 /opt

Note that scripts in /jffs/etc/config appear to run in parallel!

Getting Samba2 running

This isn't easy! when I did ipkg-install samba, it was broken (running a binary gives you a bad symbol or something about fstat64).

How I did it: use Optware, with opt mounted on your USB HD (see my script above). Yeah, you've gotta mount /opt somewhere because the samba2 package alone is >7mb!

When optware is installed and working, ipkg-opt install samba2 should fix you up.


Turn on SNMP monitoring

Dude, a free network monitoring tool

Enable snmp client on dd-wrt v23 sp2

  • snmp client dd-wrt support both snmp v1 and v2.
  • see following screenshot.

Known bugs of DD-WRT V23sp2 with WRTSL54GS

  • 192.168.1.1 will not startup after some DD-WRT GUI operation.
    • Fix, close all the exising browser window and power cycle the WRTSL54GS.
