[OpenWrt-Devel] Minimal build of OpenWRT
Hi, What packages are minimally needed to make an OpenWRT run? In kamikaze there was a "minimum release", but in the current SVN version it doesn't look that way anymore? The packages getting compiled are: - base-files - bridge-utils - broadcom-diag - wireless-tools - nvram - broadcom-wl - busybox - dnsmasq - dropbear - iptables - kernel - mtd *- libpcap* *- linux-atm* *- ppp* *- switch* *- lua* *- uci* The once in italic I believe I can remove, but can someone please confirm this because I don't want to brick another modem ;-) Thanks ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org http://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel

Not so sure about uci either. You can tweak the busybox config also a bit. - Jan ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org http://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
Re: [OpenWrt-Devel] Minimal build of OpenWRT
What is switch? I thought that was the "switch/case" command in the basic "sh"? broadcom-wl I will need because I will need the wireless, so I probably also need the bridge, the tools and iptables as well... dnsmasq is a ?dns caching daemon? and might be removed, that's true. What is dropbear? I thought that was the ssh shell in the openwrt system?

Altering the package selection won't "brick" a router, the worst it will do is render it temporarily unbootable, and OpenWrt already includes several mechanisms to help recover from unbootable situations. For reference, "bricked" is a term I use when there is absolutely nothing that can be done to recover a router -- it should not be applied to cases of nihilistic ignorance or apathy. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org http://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel

I think most of us here refer to that as a system that isn't even recoverable via serial terminal - the bootloader's horked and would require a JTAG to re-flash. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org http://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel

Switch, as in the tiny (11.4k on my mipsel) utility used to configure your switch ports and VLANs. You could write your own suite of scripts to manipulate /proc/switch, but I doubt you'll do it in less size or more cleanly. > dnsmasq is a ?dns caching daemon? and might be removed, that's true. dnsmasq provides both DNS and DHCP; if you have that residing on another server or are completely static, you can probably drop it. > What is dropbear? I thought that was the ssh shell in the openwrt system? Dropbear is your SSH server and client; you can eliminate that if you never SSH. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org http://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
Re: [OpenWrt-Devel] Minimal build of OpenWRT
Well, The default SVN build is 1.9M in size. IIRC the micro build of whiterussion was like 1.3M, so I wonder what I need to remove to get it back to that size. BTW? Does anyone know if there is already an OS driver available for the WRT54GL modems (I'm speaking about the Broadcom wireless). I tried the 2.6 build at home, but that truly broke the modem... I don't know what happened, but it simply didn't want to start. Anyone know where I could buy such cable? I'm not very good in soldering I'm afraid...

Whiterussian's build process was completely different, and I don't see much attention being paid to the systems with under 2MB of flash any more. > BTW?

Check out the forum thread on the upcoming 8.08 release for a decent discussion of this. > Anyone know where I could buy such cable? I'm not very good in soldering > I'm afraid... I presume you mean a serial cable and not a JTAG? Both of them depend on what your price range is, but there are decent electronics shops that will sell you either for under $25. If you have to be in the sub-$10 range, eBay or soldering your own are about the only way to go. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org http://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
