You could use N-Map to see what packet are flying around your network or a simple trial and error turn off all bar one device and if it's not the offender turn on a second rince and repeat -------- Original message -------- From: cory seligman <coryms.luv(a)gmail.com> Date: To: luv-main <luv-main(a)luv.asn.au> Subject: data usage metering by IP on openwrt. Does anyone know of a simple way of showing which of my machines on my home network is hogging all my data? I recently discovered that something on my network is using ~30M per hour all day and night and I'd like to find out what it is. I guess I could go around and turn each thing off and check my ISP's usage meter over a few hours, but there must be a better way of doing it. I have a WRT54GL running: Firmware OpenWrt Kamikaze - With X-Wrt Extensions 8.09 Kernel Linux 2.4.35.4 #15 Fri Jan 22 11:36:55 CST 2010 MAC 00:18:39:ED:A2:73 Device Linksys WRT54G/GS/GL Board Broadcom BCM5352 chip rev 0 Username root Web mgt. console Webif² Version r4838 I'm very lazy, so an installable package that can do this over a web interface would be ideal, but not necessary. anyone?

strange video connector
by Russell Coker 13 Sep '13

13 Sep '13

http://www.coker.com.au/bug/strange.jpg I was just given what I believed to be an ATI video card with DVI output. When I got it home I found that it didn't have a DVI connector, the above picture shows the connector with a DVI cable next to it for perspective. The connector is physically almost the same size as a DVI connector, but it has more and smaller pins. The box claims that the card has DVI-I, HDMI, and VGA. Either the card that was in the box didn't match the description or there was supposed to be an adapter in the box which was lost before I got it. Does anyone have any suggestions on how to get this going? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

panic on swap device io error
by James Harper 12 Sep '13

12 Sep '13

I am testing ceph via tapdisk rbd and am having some problems. While debugging I'm running a secondary MX on there, with errors=panic as a mount option for / so that as soon as the tapdisk backend fails it just reboots and keeps going (I keep the core when this happens). The swap device did this the other day though and it was an hour or so before the system got around to panicking and rebooting. Is there a kernel sysctl option I can set to panic as soon as an error occurs on the swap device? Thanks James

ATI video cards wanted
by Russell Coker 12 Sep '13

12 Sep '13

As ATI chipsets are much better supported than NVidia for free drivers I would like to get some ATI video cards for the hardware library. AGP and PCIe preferred, but it would be good to have a PCI card as well. If you have any such cards gathering dust then please donate them to the hardware library. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Accessing email via dns service
by Rob Rankin 11 Sep '13

11 Sep '13

Hoping someone can throw light on this issue for a Linux newbie. I'm running Ubuntu Server 12.04LTS and accessing the web via DHCP client on a Netgear router/modem. DNS service is provided through Dyndns.org Basic website is accompanied by a Moodle site which is the main focus of my operation. (support learning and teaching for U3A group) All features and functions of Moodle are operative however email cannot be sent or received. My previous experience with Moodle sites has not relied on this DNS service and I have no idea what influence their operation has on the handling of email. If someone is familiar with all the links in this chain I would appreciate some explicit advice. Cheers, Rob

petition for FTTH
by Russell Coker 11 Sep '13

http://tinyurl.com/mpo6vft While I don't think much of the way the NBN has been designed, the Liberal party has an even worse plan that will give little benefit over the current situation and most of the costs of the NBN. The above URL has a change.org petition for them to reconsider this. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

---------- Forwarded message ---------- From: Joshua Hesketh <snip> On behalf of the *linux.conf.au 2014* team we are pleased to announce that we have now started accepting early bird registrations. According to Luke John, organising director, “The start of registration represents the culmination of a lot of groundwork in planning for the conference and it's a real milestone to be at this point in the process”, “While there's still a lot to do, it's really starting to take shape now, and I'm quietly confident that we've got a great line up of speakers and topics and we are looking forward to an awesome conference”. Paul Del Fante also chipped in to offer encouragement for those of you who may feel a bit daunted by the distances. “It's Perth, it's Summer, we've got a fantastic Linux conference on, warm beaches, balmy evenings, city life, so come on over and share in our hospitality”. The *linux.conf.au 2014* early bird registrations will be open till 2013/10/13, but are for a limited number of places and may close earlier before we move on to the formal registration period, and we'd please ask anyone who registers during this time to keep an eye out for any minor issues or inconsistencies you come across.

creating TTY
by Tim Connors 10 Sep '13

10 Sep '13

Very early in the boot process, before the getty etc are fired up, I want to fire up a process that talks over a full tty. What state it leaves the console after it has finished is irrelevant - the process will finish with a reboot. I've had some element of success with openvt and screen (and running stty sane in the subshell), but they're not particularly neat, and neither of them propogate the exit value from the last command executed. And my google fu is still failing me. Anyone any idea of a simple .c program or the like that can initialise the tty into a semi-sane state and talking over /dev/tty will do the expected thing? Running 'tty' this early in the process tells me my tty device is /dev/console, but it doesn't behave like a tty, in that rlwrap fails to do the expected thing 'rlwrap: Could not open /dev/tty: No such device or address' (yes, /dev/tty is c 5 0) -- Tim Connors

Re: selinux stole my bank details (and my pony)
by Petros 10 Sep '13

From: "Russell Coker" <russell(a)coker.com.au> > Apart from a few exceptions the SE Linux design is based on a default of deny That is true and definitely adds a layer. Whether it is SELinux or containers - you rely on kernel code. Both can have vulnerabilities. SELinux is sharing the same name space with the rest of the system - so you can reach other services, files etc. by misconfiguration. People are lazy. The easiest way to get it work: allow everything for all. I just help someone to have a test instance of a website. There is a form writing data to one DB table (contact): What do I see: GRANT ALL for db.* for user anyone (no password). Regards Peter
