[edit] 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.
[edit] 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.
[edit] 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!
[edit] 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.
[edit] Turn on SNMP monitoring
This router device can be monitored by a SNMP Manager.
[edit] Dude, a free network monitoring tool
- Download Dude 2.1, Free system monitoring win32 software from Mikrotik.
[edit] Enable snmp client on dd-wrt v23 sp2
- snmp client dd-wrt support both snmp v1 and v2.
- see following screenshot.

[edit] 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.
