Yep, that's what it was designed for. I have discovered one bug - if you change your LAN network to be something other than the default 192.168.0.0, the firewall port forwarding rules won't work. No idea how to report it, tho ... Peter.

BT Home Hub, port forwarding
by Greg Thomas 25 Nov '07

25 Nov '07

[This is not strictly Linux, but I guess it's the sort of thing a number of people on -list may have played with] I was playing with the port forwarding on my BTHH the other day, and noticed something odd. If I forward port 80 from the internet to my Linux box running Apache, when I visit whatever non-RIPE address the HH has at that time (from inside the NAT range), it still presents the HH admin interface, not the Apache files - i.e. the calls aren't being forwarded. Is there a way around this other than running on a port other than 80? Anyone know if it works from the internet proper (still waiting for my BT FON to be enabled)? TIA, Greg

Don't you just /love/ flame wars? (and my two penn'orth. None of the wrt applications could really be said to be suitable for newbies. Think about how they have to be acquired. Most ADSL users either use the router supplied by their provider, or (a smaller number) they will use a router bought at PC World. The kind of user who is prepared to install openwrt tends not to be at the newbie end of the spectrum). Mick

Please, please, anyone using a BT Home hub do yourself a big favour and stop right now. Go out and buy a decent router that BT don't control. I spent some long time earlier this year playing with the hub and everything that I found bothered me (and others with whom I corresponded). The is a crippled Thomson router which is locked to BT's network. They routinely update the software remotely without your agreement. You can lock it down to prevent this, but frankly why bother - just buy a decent router. I documented this at http://baldric.net/2007/01/22/bt-home-hub-and-the-gpl/. That post also points to comments from me (and many others with similar experiences - see Kai Robinson in particular) on a good site called homehubblog. See for example http://www.homehubblog.com/2006/12/23/christmas-present-from-bt/.

Why is /etc/cron.daily happening twice
by Chris G 24 Nov '07

24 Nov '07

If I do a 'ps -ef' on my system I see the following:- root 17343 1 0 04:02 ? 00:00:00 crond root 17344 17343 0 04:02 ? 00:00:00 /bin/bash /usr/bin/run-parts /etc/cron.daily root 18023 17344 0 05:05 ? 00:00:00 /bin/bash /usr/bin/run-parts /etc/cron.daily Why does '/bin/bash /usr/bin/run-parts /etc/cron.daily' appear to be spawning a copy of itself just over an hour after it started? I have looked at the /usr/bin/run-parts script and I really can't see a reason why it should do this unless one of the scripts in /etc/cron.daily is doing something wierd and I have only added a very simple backup script there. Oh, this is on Fedora 7 by the way. -- Chris Green

Ubuntu questions
by Greg Thomas 22 Nov '07

22 Nov '07

I've just installed an Ubuntu box on an old PC (could do with an extra 256MB, but hopefully that will be sorted later today; thanks, Matt :) ) It strikes me that, unless I'm missing something, it's not quite as user friendly as I was led to believe; o There's no obvious way to get out system information; Device Manager will tell me it's a PIII, but not the speed. System Monitor will at least tell me the installed RAM, but again not the CPU speed. o "Power management" is a bit of a grandiose name, given that all it will do is turn off the PC or the monitor. No disk spin-down times, fan speed controls, etc. o There are two package managers (Update Manager and Synaptic Package Manager). The former, at least, tells me when there are updates available. I don't know yet if it will include extra packages installed by the latter (e.g. Apache WWW Server). Why two in the first place? o Disappointed that something as basic as NTP isn't installed by default. Even (spit) Windows has had this since NT4. So, is Ubuntu not quite as ready for the mainstream as I thought, or have I missed something? Greg

Surge I don't know. I can tell which router is right for /me/ - I currently use a Thomson Speedtouch (780WL). I like the fact that it provides both a web based GUI (for speed and ease of routine config) and a decent CLI for more in depth configuration. Thomson have a good guide to the CLI on-line at http://www.thomson-broadband.co.uk/codepages/content3.asp?c=7&ProductID=528 The router runs a linux kernel and busybox and unlike the BTHH (which is based on the Thomson) it isn't crippled. I also like D-LINK kit for home use. But if you really want the full flexibility of a linux firewall, then I'd go for IPcop. You /will/ need a separate box, but it has a very small footprint and will run on some pretty ancient kit (try 486 with 86Meg of RAM). Alternatively, if you really want to get your hands dirty, go for openwrt (mentioned by Adam in a different post above). Mick >What I really do care about is the hardcore access to the device.
