09:29.25ChoHagYesterday one of our servers, which is used to dump databases onto because we don't know how to do replication, had a disc failure.
09:29.57ChoHagIt was rebooted, fiddled with, and so this morning it failed again.
09:31.12ChoHagSadly, people are surprised.
09:32.03wethrinoops
09:34.04jpdsChoHag: How many times did they reboot it?
09:34.23ChoHagI don't recall.
09:34.30ChoHagAt least once. Maybe it wasn't enough.
09:34.39jpdsThree times - should do it.
09:34.41ChoHagThey did do an fsck though so that should have fixed it right?
09:35.14jpdsIt's like https://www.youtube.com/watch?v=W8_Kfjo3VjU all over again.
09:50.55cbzChoHag: propose that be repurposed as the backup server
09:51.30ChoHagIt already does pretty much all the backing up that goes on.
09:51.59ChoHag<Foreigner> Arr! Let me buy this US flag and burn it. America we hate you.
09:52.10ChoHag<America> We know. Good luck with that.

14:28.28dick_turpinJust had a customer email "We have two iphones and a Nokia E90 and need a bit of help configuring them" I've emailed with a price per phone, I await the distraught phone call

14:30.37cityLightshi all
14:30.42antiphaseWod up homes
14:30.56cityLightswell I mean , antiphase , hali and leeds
14:31.03cityLightsthe ppl I know
14:31.29cityLightslet me start off with a linux question
14:32.31cityLightsassume I have eth0 - connected to the internet and ppp0 which is established using l2tp and ppp0 gw is the default gateway
14:33.06cityLightsI run a vpn server on the machine and I want the clients to connect to eth0 and be answered via eth0
14:33.34cityLightsI dont know all the subnets the clients will use to conenct, so, how can I solve this?
14:34.02dick_turpinantiphase: Close actually at least as far as our customers are concerned, I want £65 per unit. What's the betting they ring one of the gaffers "Have you seen what Pete says!"
14:38.37dick_turpinChoHag: [linuxjobs] Senior Linux (Red Hat) System Administrator, London £60K
14:45.05antiphasecityLights: Why do you use your VPN as a default gateway?

17:44.24cityLightsantiphase: as requested here is the network I mean: http://img819.imageshack.us/img819/5553/diagram1y.png
17:47.54antiphaseCan you run scripts when clients connect to the VPN?
17:49.25antiphaseI might just be confused now
17:52.39cityLightsinitially before I connect to the l2tp server I got only one NIC , eth0 - and it provides the defualt gateway to the internet
17:53.07cityLightsso when a client connects to the 1.1.1.1 address it is replied using the 1.1.1.1 address
17:53.56cityLightsnow when I establish the l2tp and use it as a default gateway, any out going communication is via the 2.2.2.2 address - right
17:54.25cityLightsso is the client connects to address 1.1.1.1 it is answered with the 2.2.2.2 address
17:54.28cityLightshow to fix
17:54.42cityLightsthe pc is a linux box
17:54.54cityLightsso I can add any kind of routing
18:11.26antiphaseIf your PC connects to eth0's IP address, that's where the replies will come from
18:11.42antiphaseor maybe not
18:11.53antiphaseI remember this from a few weeks ago now
18:12.22antiphaseI think I said you need more than one routing table, but I don't know if you can mark inbound traffic for outbound routing
18:14.06antiphaseI'm really quite confused by your diagram though
18:14.29antiphaseIf your remote PC connects to your "other" PC with a VPN, there's not a problem anyway
18:30.04*** join/#gllug mikejw (~mikejw@84.19.55.162)
18:38.50cityLightsI dont understand that last line
18:39.32cityLightsdo you mean the "phone" connects to the pc using the 1.1.1.1 address?
18:40.55cityLightsI mean when I ask these question - google responds with source base routing
19:58.34antiphasePhone?
19:59.02cityLightsthe remote host in the picture that is a client to the vpn server
19:59.45antiphaseAnd your VPN server can't add static routes based on where a client is coming from?
20:01.46cityLightsright
20:02.06cityLightsthe reason is that this client may connect from any coffee shop wifi
20:02.25cityLightsI mean this used to be a case for source based routing- right
20:02.38cityLightsthis is what I read about in google
20:03.21cityLightsnow , the idea of marking incoming traffic from ppp0 to destiguish it from traffic from eth0 - sounds good
20:03.24cityLightsbut how
20:03.31antiphaseYou need to provide some information to cause correct routing to happen at some point; either your VPN server needs to add a static route when a client connects, or you need to somehow provide other information in advance, or there's an outside chance of some hack involving iptables and multiple routing tables
20:03.44antiphaseSource routing hasn't been viable for at least 15 years, if not longer
20:04.06antiphasePeople will just drop your traffic or fail to honour routing information
20:04.30cityLightsso the easy way IS to mark traffic from ppp0
20:04.33antiphaseIncoming traffic from ppp0?
20:04.34cityLightshow ?
20:04.42antiphaseYour diagram is shit, to be honest
20:04.51cityLightsiptables -i ppp0 -MARK FF ?
20:05.10cityLightsok how should I draw it then?
20:05.32antiphaseYou need to show where connections are actually made, so it's clear why the problem exists and what needs to be done
20:05.37cityLightsthe fact that I draw it wrong - means I still strogle
20:05.49cityLightsok
20:05.56antiphaseAt the moment it's not clear which links are where and which are VPNs
20:06.11cityLightshow can I demonstrate that ppp0 is virtual via eth0?
20:06.42antiphaseProbably byindicating that there's only one physical interface
20:07.40cityLightsI will remove the l2tp srv block
20:08.23cityLightsand the isp block
20:22.30antiphaseI might have a solution for you
20:23.56antiphaseIt's 50/50 if it will work though
20:29.17cityLightsis this better?
20:29.22cityLightshttp://img156.imageshack.us/img156/971/diagram1.png
20:29.50antiphasehttp://pastebin.com/5jGw3u5B
20:30.36antiphaseI think the picture is more informative now. Not sure I'd do it that way, but it doesn't matter
20:49.13cityLightsseems fine, lets see it work
20:49.36cityLightsbtw, listening to gary numan
20:51.33cityLightsoddest part today, was the end of the interview:

20:52.24cityLightsthen he repied , and a car?
20:52.35cityLightsnow what should I replay to this?
20:52.42cityLightsno thanks
20:52.45cityLights?
20:53.00cityLightsmeaning a company car
21:17.30antiphaseWell I'm going to go to bed
21:17.44antiphaseIf your thing still isn't working we'll have to see about it another day
