 + 
 +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 [http://www.dd-wrt.com/wiki/index.php/Optware 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 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

[edit] Enable snmp client on dd-wrt v23 sp2

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