We did have a chat about that in IRC and it was pointed out that Netcat might not be able to make to do it without a script. At least it was some help in enabling you to find socat ;) -- David Reynolds david(a)reynoldsfamily.org.uk

Intercepting TCP comms
by Mark Rogers 29 Oct '08

29 Oct '08

I'm trying to write some application code which will communicate via a TCP connection to a device. I have complete control of my application (which runs on a server to which I have SSH access) and no control of the device. At the moment my comms code is not working and I want to debug it at a binary level. For sake of argument, let's say the server connects to port 10000 on the device. I want to (a) listen on port 10000 on my desktop, (b) configure the server to think the device is my desktop, (c) forward any data I get on port 10000 to port 10000 on the device, and send any replies back whilst (d) logging everything going to/from the device. Any suggestions as to how I might do this? Or some suitable terminology to Google for? My desktop is Ubuntu and I have the luxury of a GUI there if I need it. The application is a Modbus/TCP driver for an industrial unit if anyone is interested. The protocol is simple, but binary. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

<<Just upgraded to this. Am I alone in finding it very disconcerting?>> <<Perhaps most disconcerting is the way autocompletion now seems to work.>> It was bit odd the first time I upgraded. I couldn't see how to go back several pages it's all become clear now. The spellcheck feature is a genius idea so that also helped to win me round. I don't mind the autocomplete feature. Most of the suggestions are of url's that I have typed in or looked at recently. The only wrinkle in this otherwise delightful browser is its tendancy to pick unicode/whatever for the character encoding so the question mark in the diamond appears where a pound sign should be etc. It can be changed manually but it has to be done fairly frequently as there is no option to save the setting. Sigh. I hope this gets fixed. Bev. -- _______________________________________________ Surf the Web in a faster, safer and easier way: Download Opera 9 at http://www.opera.com Powered by Outblaze

Ipswich ALUG meets: change of day discussion?
by samwise 21 Oct '08

21 Oct '08

Hi, all. At some point I promised someone, I forget who, I'd raise a discussion on the mailing list about whether we should change the "third monday" rule of thumb of the Ipswich ALUG meets. We've tailed off on numbers a little bit recently, tho that might just be the fine summer weather ... :) Anyway, so long as it doesn't majorly trouble any of the current regulars, then I don't see any problem with rearranging the day. So ... is there anyone who would find it more convenient* if we changed the date and, if so, what days would you prefer? Peter. * Yes, it would probably also be more convenient if I could regularly remember to send the reminder email out the week before. I'm working on that ... ;)

PGP/GPG private key management for offsite backups
by Srdjan Todorovic 21 Oct '08

21 Oct '08

Hi, I've got an offsite backup of some of my data, in case my apartment burns down etc. Since I dont have full control of the backup machine, I encrypt my data using PGP/GPG, and then upload to the backup service host. This is so far well and good. The GPG private key is on the machine in my apartment, beside possibly a copy being on some old floppy or CD-R. What happens if my apartment burns down? I will have my data backed up nice and snug on the backup service host. But since I cannot remember a 4096bit PGP private key pair, I would be in a bit of a bind. Could anyobne please offer some strategies to overcome this? I think someone on irc suggested some time ago that I mail my parents a copy of my key pair... but I'm not sure I'd want to do that (they might lose it). Thanks Srdjan

Why does Ubuntu set my resolution to 1152x864?
by Chris G 20 Oct '08

20 Oct '08

I'm trying out Ubuntu 8.10 on my new system. It insists on setting the resolution in X to 1152x864 by default. This is a real pain because it looks awful on my Dell display which has a native resolution of 1600x1200. I can set the user desktop to 1600x1200 but that doesn't change anything else, for example the gdm login is still at the lower (fuzzy) resolution and if I change to anothe window manager that's at the lower resolution too. Where does the 'default' come from now that there are no explicit resolutions in xorg.conf? Can I put 1600x1200 explicitly in xorg.conf and, if I do that, will it cause any problems? -- Chris Green
