IPTables and Me - they don't mix.
by Barry Samuels 29 Aug '08

29 Aug '08

My setup: Debian Testing (up to date) Kernel 2.6.24 My router has a firewall with the SSH port open. I run a FireStarter software firewall, which blocks SSH access, on my computer together with Knockd. Knockd runs a script which adds or deletes an IPTables rule to allow SSH access. The knockd script part works insamuch as it adds the required rule. The problem is that the firewall on my computer still blocks SSH access. This is so that I can access my computer when away from home and that's the only time I can test or try it consequently it's all rather long winded. SSH access is by key only and login is prohibited. First I added a rule to allow SSH access using the FireStarter GUI interface then I had a look at an IPTables listing to see what it had generated. I used that rule in my knockd script. The next time I went away I found that it didn't work - I still couldn't get access. The last rule I tried I had modified myself after reading the man pages and that didn't work either. So I'm now stumped. This is my last effort: iptables -A INPUT -p tcp --dport 22:22 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT iptables -A INPUT -p udp --dport 22:22 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT I don't know whether the UDP rule is required but I thought it wouldn't do any harm. If anyone can point out what I'm doing wrong I'd be most grateful. -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

Mobile Linux, more thoughts and questions
by mark fernandes (IFR) 28 Aug '08

28 Aug '08

<UNLURK> I've got an Asus EEEPC (701) which I use with a 3G Mobile Broadband USB dongle (HUAWEI E220). I just used the add network wizard and followed the prompts and voila! it was setup. Works quite well (even on the train - Useful when stuck on Norwich to London line!). I have had minor problems with random disconnects but I suspect that this is to do with mobile coverage and contention. Works well enough for casual web-browsing and e-mail (which is what I use it for). Suspect may not be up for beefier things like iplayer etc. :-) Hope that this is helpful, Mark </UNLURK>

Mobile Linux, more thoughts and questions
by Chris G 27 Aug '08

27 Aug '08

Having looked at the Nokia N810 (reviews etc.) I've decided it probably doesn't offer the mix I really want. In particular it lacks phone capability (i..e. it has no SIM) so I'd need to carry a phone as well as the N810 which seems a bit silly. So I'm still kicking ideas around, I'm after GPS ability (for logging and for motorbike), a mobile phone and mobile computing which, for me, essentially boils down to being able to make an ssh connection through the mobile phone data connection. A browser for Googling would be nice but is less essential. I think this probably looks like several devices with a mobile phone and a data connection at the centre. Does anyone here use a mobile phone data connection with an Asus EEEPC, is it easy to set up and usable? If it was then it gives me a much nice keyboard for ssh than any keyboard on a smartphone or whatever. Alternatively a smartphone (like a Treo 680) with ssh installed would work too, much more difficult keyboard but more portable. Any other ideas, comments, etc. regarding getting a "terminal on a mobile phone" that's usable, portable and cheap? Once I've decided the neatest solution to the above I can add a GPS logger easily enough and I suspec the motorbike GPS navigation just ends up as a separate device. -- Chris Green

What about the iPhone? I don't have one myself, but I hear there is quite a selection of applications for it, and it has built in GPS I'd be surprised if someone hasn't already figured out how to put linux on it... -----Original Message----- From: main-bounces(a)lists.alug.org.uk [mailto:main-bounces@lists.alug.org.uk] On Behalf Of Chris G Sent: 27 August 2008 14:47 To: main(a)lists.alug.org.uk Subject: [ALUG] Mobile Linux, more thoughts and questions Having looked at the Nokia N810 (reviews etc.) I've decided it probably doesn't offer the mix I really want.

Routing table via DHCP on Fedora
by Dan Hatton 27 Aug '08

27 Aug '08

Dear All, The dhcp-options manpage says `NOTE to Fedora dhclient users: dhclient-script interprets trailing 0 octets of the target as indi- cating the subnet class of the route, so for the following static- routes value: option static-routes 172.0.0.0 172.16.2.254, 192.168.0.0 192.168.2.254; dhclient-script will create routes: 172/8 via 172.16.2.254 dev $interface 192.168/16 via 192.168.2.254 dev $interface' If I suspect that I'm getting a messed up routing table (i.e. not what the DHCP server administrator intended) as a result of this, what should I do to diagnose and/or fix it? -- Thanks, Dan

19" CRT Monitor, Free to a good home!
by Simon Elliott 27 Aug '08

27 Aug '08

Hello everyone, I've got a 19" Dell CRT Monitor... Don't have the space for it any more. It runs a pretty nifty 1280x1024, still in good working order and it's just sitting in my living room. My landlord wants me to get rid of it, anyone want it? http://www.flickr.com/photos/sionide/2801352124/ If you can come and collect it, you can have it! NR1 3AY, email me if you want it :)

EeePC battery runs down ...
by Ted.Harding＠manchester.ac.uk 23 Aug '08

23 Aug '08

Hi Folks, Knowing there are a few Eee PC owners out there, I'd like to compare notes on the following. I have a standard Eee PC 900 (Linux) with the standard ASUS battery. I've observed that if the machine is "powered off" (via the GUI: logoff -> shutdown) when the battery is fully charged, a few days later the battery may be substantially discharged (e.g. currently at 20%, on a previous occasion dead flat). Might this be due to slow internal leakage in the battery? Might the computer in fact be quietly ticking over in the background even though nominally "shut down"? Would a different battery make a difference? Just a few questions -- I'd be interested in what others think. With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 23-Aug-08 Time: 18:09:03 ------------------------------ XFMail ------------------------------

CSS question, just a bug/quirk or what?
by Chris G 21 Aug '08

21 Aug '08

I wanted tables with no borders at all, after mucking around for a while with the CSS I found that:- table.docutils, td, th { border: 0 } works, but that:- table.docutils td th { border: 0 } doesn't work. According to CSS documentation those commas are wrong but they've made it work for me. Is this just a quirk of Firefox (2.0.0.12 on Linux) or am I missing something (quite likely!)? -- Chris Green

by Mandy Young 19 Aug '08

19 Aug '08

Hello Everybody, Does anyone out there know anything about the hardware suitable and if there is any open source software available for bluecasting that will run on a linux server? I have checked around and I can only find companies that offer a complete service for Windows. Thanks, Mandy. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
