dialup to UKFSN
by Ted Harding 17 Aug '05

17 Aug '05

Hi Folks, Are any of you using dialup via a modem to ukfsn.org's dialup service, and currently experiencing connecion problems? If so, I'd be pleased to compare notes (it may just possibly be a faulty modem, but it's unique to UKFSN). Thanks, and best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 17-Aug-05 Time: 21:32:43 ------------------------------ XFMail ------------------------------

Guys, I am after a little advice. Which package is best for network performance monitoring ? I am familiar with MRTG and Cacti. Is there anything better out there, or are these the ones to use? -- Regards Andy Trevor Technical Director Cutter Project Limited www.cutterproject.co.uk

C programming style question
by Chris Green 12 Aug '05

12 Aug '05

As a pleasant background task I'm re-programming astime (an X clock) to work more the way I want it to. It's currently written in ANSI C and shows evidence of different programmers having been involved at different times. Nothing wrong with that but it is a bit inconsistent in the way it does things. I'm trying to improve its style as well as making it do what I want, so, finally to my questions! It has *lots* of configuration parameters which specify things like colours of the hands, font to use for text, size of clock, etc. etc. There's something like 50 or so of them. In the existing code some are globals, some are members of a structure called 'state', there appears to be no good reason for this division. The problem is how to 'hand them around' between different parts of the code, if they're all globals it's easy to initialise them as well as create them in a file called, say, astime_config.c, this avoids the need to create them and *then* initialise them separately. However, apart from so many globals creating problems of its own, it then requires a 'extern' declaration for every value in a header file so that other source files can access the values. On the other hand if they're all in a structure (or maybe two or three structures) the structure can be declared in a header file and only a few 'extern' declarations are needed (one for each structure). However initialisation is then messy as it's of the form:- struct Fred fred = { <lots of numbers and strings> }; where it's difficult to document and keep tabs on all those constants. Is there a good way around this problem or have I just got to bite the bullet and decide on one or other of the above and go with it? C++ solutions are just as welcome but I can't see that helping really. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

Eeeeep! I forgot to send this reminder! Tonight is Norwich ALUG Social night...
by Brett Parker 11 Aug '05

11 Aug '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I've been busy, and I entirely forgot to send the reminder for the 2nd Thursday ALUG Social night... It's tonight! Thurs 11 Aug 2005, starting from ~ 8pm ish in the Reindeer on Dereham Road in Norwich. As is usual, I shall probably be there from ~ 7.30pm ish, I'll be wearing a blue shirt and jeans, probably sitting at the table just to the left or right of the door (depending on which is available when I get there), smoking (or at least the tin and lighter will be on the table), and there will be a pint glass full of something bitter tasting in front of me. (That should help anyone out that's looking for us that hasn't been before)... WARNING TO THOSE THAT HAVE MET ME BEFORE: I am less hairy again, the beard has gone, I am still me but you might not recognise me at first glance. Usual random topics will come up, beer, brewerys, cool projects, etc, etc. Directions to the Reindeer can be found at: http://www.alug.org.uk/venues/reindeer.html Someone remind me that I need to send a patch to mjr with some more dates etc, it appears that the last meeting listed on the meetings page was last month (ooops!). Pictures of some of the regulars, and irregulars, and, well, just some pictures of people that might or might not turn up are available from: http://www.earth.li/~noodles/Photos/2005-01-ALUG-Xmas/ Which is from the ALUG Christmas meal (which was very very good). There's some other pictures somewhere, but I can't for the life of me remember where at the moment. Hope to see lots of you there! - -- Brett Parker web: http://www.sommitrealweird.co.uk/ email: iDunno(a)sommitrealweird.co.uk -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFC+21PEh8oWxevnjQRAjJmAKCVy9HFRruzpRe5Y0j5XRRhZ1q6GgCgorUy 5leueataPVHDZgxezsBEv0g= =WrT2 -----END PGP SIGNATURE-----

Monitoring router firewall logs, how to work out what's doing what?
by Chris Green 10 Aug '05

10 Aug '05

I have a Zyxel Prestige ADSL router which does my NAT and is also a firewall. I'm fairly happy that I have the firewall set up correctly, however I'd like to be able to interpret what I'm seeing in the router logs. For example over the past few minutes I see lines like the following and some of them I don't really understand what's talking to what. Aug 10 12:30:31 zyxel RAS: src="192.168.13.3:137" dst="192.168.13.255:137" msg="Firewall default policy: UDP (L to L/PRESTIGE)" note="ACCESS FORWARD" devID="D9C103" cat="Access Control" OK, this is a Win2k computer on my LAN talking to the ISDN router, I can understand this. (The ISDN router is there for historical reasons, it's not used at the moment) Aug 10 12:31:16 zyxel RAS: src="192.168.13.44" dst="224.0.0.251" msg="Firewall default policy: IGMP (L to L/PRESTIGE)" note="ACCESS FORWARD" devID="D9C103" cat="Access Control" This is from a networked HP 7310 printer but I don't understand the dst address, where does 224.0.0.251 come from? It has no relation to my 192.168.13.xx subnet. Aug 10 12:31:16 zyxel RAS: src="192.168.13.44" dst="224.0.1.60" msg="Firewall default policy: IGMP (L to L/PRESTIGE)" note="ACCESS FORWARD" devID="D9C103" cat="Access Control" This (again from the printer) always appears immediately after the other printer one. Another 224.0.x.x destination. Aug 10 12:33:34 zyxel RAS: src="61.55.188.229:3381" dst="84.51.144.229:1433" msg="Firewall default policy: TCP (W to W/PRESTIGE)" note="ACCESS FORWARD" devID="D9C103" cat="Access Control" Now this I don't follow, it's from the 'outside' to the Zyxel router (I have the static IP 84.51.144.229 from my ISP). Is this a probe of some sort? The port numbers seem rather odd. Should the router be telling me what it's doing with this, e.g. is it blocked/refused? Aug 10 12:34:26 zyxel RAS: src="82.76.43.200:1627" dst="84.51.144.229:1433" msg="Firewall default policy: TCP (W to W/PRESTIGE)" note="ACCESS FORWARD" devID="D9C103" cat="Access Control" Another similar one. Aug 10 12:34:54 zyxel RAS: src="192.168.13.1:32978" dst="200.23.51.205:123" msg="Firewall default policy: UDP (L to W)" note="ACCESS FORWARD" devID="D9C103" cat="Access Control" This is my Linux box talking to cronos.cenam.mx, by the sound of the name it's probably asking what the time is using NTP. Yes, that's it, 123 is the NTP protocol, so I'm happy with this one. Aug 10 12:34:59 zyxel RAS: src="218.94.232.240:2611" dst="84.51.144.229:1433" msg="Firewall default policy: TCP (W to W/PRESTIGE)" note="ACCESS FORWARD" devID="D9C103" cat="Access Control" Another one to port 1433, which turns out to be "#Microsoft-SQL-Server" what on earth does this suggest? -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

USB
by Bob Dove 10 Aug '05

10 Aug '05

Hi folks, Further to my earlier message; If I take the memory card out of the camera and insert into USB card reader - the USB driver recognises it as a new drive and the data is accessible. Using the camera supplied USB cable, the camera software has to be installed or it is not recognised. Cheers, BD.

Keeping time correct
by Chris Green 10 Aug '05

10 Aug '05

My Linux box runs all the time and, while the system clock is reasonably accurate, it does drift a bit. What utilities and time source do others here use to keep their clocks accurate? Do you just run netdate with a known good time source from your crontab or what? -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

I have 10 copies of the pukka (Live+Install CDs in a card wallet) versions of Ubuntu 5.04 in my hot and sweaty hands. 5 are for the x86 architecture and 5 are for 64 bit (AMD64/EM64T) architectures. If anyone would like a copy of either (or both) sing out and we'll arrange getting one to you.
