Steps for creating a NoCat [http://www.openwrt.org/ Openwrt] Build on a Linksys WRT54g or gs

"OpenWrt is a linux distribution for the Linksys WRT54G. Instead of trying to cram every possible feature into one firmware, OpenWrt provides only a minimal firmware with support for add-on packages. For users this means the ability to custom tune features, removing unwanted packages to make room for other packages and for developers this means being able to focus on packages without having to test and release an entire firmware."

To use nocatsplash on openwrt, you need to do some fiddling.

• Get a current version of a prebuilt OpenWrt binary image with MAC support and iptables enabled here: BR

OpenWRT binary (CVS 10-Dec-2004) [http://bjencks.net/~brj/openwrt/openwrt-g-code.bin WRT54G] md5sum: 37664add5eafd051ec07e339d26f0e37 BR OpenWRT binary (CVS 10-Dec-2004) [http://bjencks.net/~brj/openwrt/openwrt-gs-code.bin WRT54GS] md5sum: 459df29183d7afcb8ffbbac3b7726c3f BR

• BROr

• Get a working buildroot following the instructions on the [http://www.openwrt.org/ openwrt] site.

  • First, you need to enable the MAC matching support in iptables, both in the kernel and as an iptables module.
    • To enable the iptables module
      • edit buildroot/sources/iptables-openwrt-extensions.patch
      • add 'mac' to the end of the PF_EXT_SLIB line.
    • For the kernel module
      • Edit buildroot/sources/openwrt/kernel/linux.config
      • Set CONFIG_IP_NF_MATCH_MAC=y
  • Do a full build ("make"). This will need some fiddling, mostly with the snapshot date in the main Makefile.

• Load the image onto your WRT. The openwrt website has some good [http://www.openwrt.org/userguide.html#before_you_flash instructions] on how to do this.

• At this point you should telnet to the WRT, edit /etc/ipkg.conf to add the main openwrt package directory

  src openwrt http://www.openwrt.org/ipkg

  ipkg update and ipkg install dropbear. Start sshd, and make an initscript to start it on boot. Then disable telnet, and use ssh to log in from now on.

• Now, you can either use the [http://bjencks.net/~brj/openwrt/nocatsplash_nightly-5_mipsel.ipk ipk] I built

  • BROr

• build it yourself. I recommend building it yourself, so you can tweak it later more easily.
• To build it yourself

  • make libglib: make `pwd`/build_mipsel/staging_dir/lib/libglib.a

  • unpack the [http://bjencks.net/~brj/openwrt/nocat-openwrt-r5.tar.gz tarball] into your buildroot

  • run 'make packages'.
  • To modify it
    • edit the patch buildroot/sources/nocatsplash.patch,
    • edit make/nocatsplash.mk and increment the version number

    • then make nocatsplash-dirclean; make packages.

      • BR

(The patch adds mac address logging, and more levels of logging. I recommend level 1, which shows auths and timeouts only. The logging part was by the ewrt people)

Troubleshooting

Q) I have flashed the OpenWrt bin on but whenI try to telnet in my old username/pswd simply do not work. I even reflashed it with the previous firmware (ewrt) and test the username/password just to be sure. Any thoughts? (TomHiggins)

A) try root/<your old linksys admin password or root/<no password>

• I tried this and still no go on two of the wrts I flashed to openwrt. I think perhaps we will have to peek into the NVRAM and see whats being help there under other firmwares. Is there any chance that OpenWrt overwrites the NVRAM on install? (TomHiggins)
