[Hampshire] Hard drives for sale
Hi All, I have 4 of these WD green drives going if anyone is interested: http://i.imgur.com/ANAh9gv.jpg I had 7 in a home NAS, two have been repurposed and one went into a PC. They are all working and they haven't seen very heavy usage despite being in a NAS. It was a home media NAS so it needed lots of space but not high performance. If anyone is interested let me know, collection only from Southampton or somewhere not too far out (I can also deliver by car). Indivudally or all together for any reasonable price, since they work I just want them to go somewhere rather then the recycling.

[Hampshire] Free Original Xbox
Hi All, I recently moved house and have various bits and bobs that are free to a good home, if anyone wants any of them please let me know (first come first serve). I haven’t got room for them anymore. First up I have an original Xbox (not even an Xbox 360!) whichI have chipped so you can copy games to the hard drive and play copied disks (I have also fitted a larger than standard hard drive, 80GB I think). It has two controllers and a few old games like Rainbow 6, Burnout 3, Sega GT 2002, Halo 1, plus whatever games are copied to the hard drive. I guess this is considered retro gaming now? So if you’re into that, its free. I have more stuff I haven’t unboxed as yet. It can be collected from Southampton (or I can deliver it to you in Southampton) or in Reigate or Leather, I am circulating between though locations regularly.

[Hampshire] Free Xbox 360
Hi All, I have an Xbox 360 going for free. I re-flashed the DVD drive so it can play content from non-authentic disks like writable DVDs you’ve bought from the shops, hay, nudge nudge, wink wink, hay, nudge wink, hay hay ;) FWORRR! It has SD and HD TV connectors, 2 wired controllers, head set, Ethernet cable wireless adapter, power cable. I have 3 original games; Forza 2, Oblivion and Unreal Tournament. I had a stack of games that aren’t, erm, “originals”, but I can’t find them at present. I will try and dig them out, or you can use your favourite torrent site. I re-flashed the DVD drive with modified firmware a couple of years ago. The down side is you can't use xBox live. I lent this xbox to a friend for a year and I haven't turned it on sinse getting it back but I think they might have taken it on line. What this means is that the system will have updated and removed the alternate firmware so you can't play copied games anymore but can play online. If that is the case you can re-flash the firmware using a Windows PC, its not too difficult. Free to a good home, still unboxing my stuff so maybe more to come. It can be collected from Southampton (or I can deliver it to you in Southampton) or in Reigate or Leatherhead, I am circulating between those locations regularly.

[Hampshire] Free PCs
Hi All, I have 2 PCs that are free to a good home. I am going to drop them into my office tomorrow in central Southampton and I will wipe both and install a fresh copy of both on Ubuntu to ensure they are both working and nothing further. PC1; 2.0Ghz Intel Core 2 Duo 8GB DDR2 RAM 250GB SATA HDD 600W PSU nVidia GT210 PCI-E graphics card DVD-RW Motherboard has on-board sound, USB and wired Ethernet. PC2; 2.15Ghz Inter Core 2 Duo 4GB DDR RAM 80GB SATA HDD 300W PSU Missing a graphics card I think I have a spare DVD-RW on my desk at work I can put it in Motherboard has on-board sound, USB and wired Ethernet. PC1 is in a typical PC sized case (Is this called midi ATX?). PC2 is in a massive tower. I was a home media server. It has 8x 3.5 HDD bays and 3 or 4x 5.25 DVD drive bays. PC1 is 5 years old and PC2 is 4 years old (so both have wear on their cases, PC2 has more scratches than PC1). Neither are mean computing machines. If you want a basic machine for doing something basic PC1 is for you. If you want to mod PC2 for a home server, that case is what you need. I will follow this up with some pics tomorrow. Also free to a good home; -1x PCI sound card, Sound Blaster Audigy 2 -1x PCI SATA expansion card, Adaptec something with 4x SATA Connections. -I also have many SATA cables to chuck out due to decommisioning PC2 as an old media server and many 1x Molex to 2x SATA power connectors. All for collection only from central Southampton, must be this week. I'm moving so it all needs to go ASAP! I won't be giving away parts of the PCs as I'm in a rush to get rid of them, they must go whole.

There is a crossover point which you need to figure out for your self, where writing a bash script to do something is no longer useful because they run rather slow, or it would be cumbersome. At that point you end up either writing Perl or PHP scripts for example, or writing in Python or Ruby. I have a few goals which I want to delve into further.

Hi Chris, I'd be more than happy to throw in my two peneth worth if you can sort out SSH access (I help maintain several Apache servers, although non are resource constrained but they are all reasonably tuned, so I may have some crossover of knowledge to offer) ? Have you looked at the server (via SSH) whilst it's running slow to work out where the bottle neck may be? So you can try `iotop` to look at disk IO, `iftop` will look at network usage, and `htop` is a slightly prettier (but arguably less informative) `top` command. Also, have you looked at options in the Apache config for settings like the max number of threads, and connections, keepalive timers etc (check out this URL for some common ideas: http://httpd.apache.org/docs/2.2/misc/perf-tuning.html). Have you looked into MySQL tuning also?

Re: [Hampshire] Improving Home Broadband Talk - Follow Up
Hi all, I have received some more questions about line stats; So what actually determines your broadband speed is something call the sync rate, which is how fast your modem in your house and the DSLAM on the other end of the telephone line in the exchange are happy to communicate at. The content of my talk relating to your BT cabling etc were all tips towards inproving the sync rate on your line. The main factoring in determining your sync rate is your telephone line length from the exchange to your home. The longer the line the higher the attenuation (so this means the signal is getting weaker as it travels a longer distance). If you log onto your router/modem at home you will see various statistics such as sync rate, signal to noise ratio, attenuation, output power and receive power. I have just logging into my router at home and pulled the following stats from it; Downstream Upstream Rate (Kbps): 9214 kbps 695 kbps SNR Margin (dB): 6.2 8.8 Attenuation (dB): 42.022.2 Output Power (dBm): 0.0 12.3 I have a sync rate of 9214Kbps down stream. When your modem boots and initiates the DSL line it has a conversation with the DSLAM, both ends measure the noise on the line, and the attenuation (so signal loss from distance) etc and the DSLAM dictates what the sync rate will be. I won't be able to get 9.2Mbps because there will be some overhead room here. I have just done a speed test to http://speedtest.vostron.net/ and held a comfortable 7.74Mbps download rate. The sync rate is always slightly lower than what the DSLAM thinks you line can handle as noise is always coming and going from your line throughout the day. This means I perhaps could hold a sync rate of 9512Kbps or slightly higher, but my connection may periodically drop out when someone in my shared house uses the microwave or plays soldiers with some walkie talkies. So this is a safety net to keep your connection up by sacrificing a little bit of speed. If your sync rate is too high for the quality of your line you will experience transmit (and receive) errors on your connection. If you are experiencing a lot of errors any good ISP (such as Vostron :P) should after a quick phone call be able to change the stability option on your line. They can tell the DSLAM to be more reserved and force it to sync at an even lower rate than it would normally, sacrificing some speed for stability (we can in fact stage this down several times putting you down to a super stable option which chops 25% (or more) of your speed off, for stability. You should be able to check for errors by logging into your router/modem and looking for the error counters such as FEC errors or CRC errors, Reed Solomon errors and Drops. Look at these values in relation to the number of packets (or cells or frames) transmitted and received. Looking at mine now in the downstream direction, my router has transmitted 18,698,683 packets and encountered 10,859 errors. That is not very good, that is roughly one error every 2000 packets. I currently have an absolutely rubbish router (as I lived in a shared house, its out of my control!). I have just pulled these from a router in my office remotely; Cells: 293077295 Reed-Solomon EC: 0 CRC Errors: 23 Header Errors: 13 A good line like that should only be getting roughyl 1 error in every million packets/cells. This is a good page about the errors: http://www.kitz.co.uk/adsl/error_correction.htm Any good ISP should be able to turn on interleaving on your line to improve the stability, however this will add on some latency (delay) to your connection. It shouldn't be horrendeous unless you are a finanical trader or hardcore gamer, we have plenty of VoIP customers on lines with interleaving enabled. This is a good page explaining interleaving: http://www.kitz.co.uk/adsl/interleaving.htm Have a read through this page; http://www.kitz.co.uk/adsl/linestats.htm And this one: http://www.kitz.co.uk/adsl/linestats_explanation.htm They will tell what all your various line stats mean and give you an indication of what you should be able to achieve. If you are on ADSLMax (so not ADSL2/2+) see the following link for the various IP profiles your sync rate is going to be mapped to: http://www.kitz.co.uk/adsl/IPprofile.htm This site is reasonably accurate at guestimating what you should expect if you pop your stats into its calculator for either ADSL1/2/2+: http://www.coolwebhome.co.uk/calc/calculator.php If you have an attenuation of 60dB or higher, may the force be with you. 60dB is typical of a line length of greater than 5.5Km which is really at the tip of what ADSL will operate at, at all. I hope that proves useful somehow!

Hi (again) all, I had some questions on contention; Two great articles you can read on contention are these two; http://aaisp.net.uk/kb-broadband-contention.html http://www.beyondbroadband.coop/book/export/html/65 The main point to take from this is that contention isn't always bad perse, just given the raw ratio; you need to know what it is relation two (what speed each end users is promised and what speed the link they all share is). Also note that contention isn't really an issue any more. A few years ago before I started learning about the various DSL technologies used to delivered broadband I had this discussion with ISP engineer from various ISP : http://null.53bits.co.uk/index.php?page=conversation-on-contention-ratios This is still valid now. BT have moved away from selling on contention ratios and now opt for an assured minimum service level, i.e. on broadband package X you should always get 500Kbps, even at peak times.

[Hampshire] Meeting Talks
Reviving an old thread :) When this thread was first alive the wiki was down, this page is up and running now; http://www.hants.lug.org.uk/wiki/MeetingSuggestions/Talks I think the talks are a really good way of promoting the open sharing of information amongst the luggers, and bring new faces to the LUG meetings (there are three great talks happening this weekend if you didn't know already!). I am quite happy to be the one to record talks ( although I would have to be loaned a camera :D ) and either provide free hosting for the video files or be the one to upload them to YouTube (to tie in with the currently running social media thread, HantsLUG could have a YouTube channel? Again I would happily volunteer my self to run this). Can a site admin chime in here please? Currently account creation is disabled, is this going to be re-enabled ever? It would be nice if LUG members could freely sign up and request/offer talks.

Had another crazy idea; you can set up a box to auto run a script when a USB drive is attached, and a new file system mounted. Have a USB pen to hand that has a file with a random name in its root like 398hhwjhAweE. When a USB drive is mounted, the on mount script will run and and check if a file called 398hhwjhAweE is in the root, and if so, run shutdown -h now.

[Hampshire] Meeting Talks
Howdy all, There was a surryLUG post recently about the next bring-a-box meeting, which led me to cruise the surreyLUG site. There I saw they have two things; The first is a page of requested talks, where users can vote for talks they want to hear about, and submit topics. The second was on the bring-a-box page people can offer to give a talk at these meets, and fill in the days schedule. SurreyLUG is a bit too far from me, so I'm a hantsLUG goer only (well soon, still waiting to go to my first meeting, just been super busy this year!). So my question is; Is there any plan to have talks at hantsLUG meetings, with a similar pages where users can suggest and vote on topics, or does this already happen and I've missed the wiki page on this? It's good (I believe) to make a request accompanied with an offer so to get us started, I'm a network engineer for an ISP. I can offer talks on routing and switching, VPNs, networking protocols (Ethernet, MPLS, IP, TCP, ISIS, OSPF, BGP etc) and telephony. I'd like to hear about assembly, c++, high performance computing and clustering, high availability technologies, MySQL, SANs, Apache, Advanced BASH scripting. So not all that I offer or request is strictly Linux based to be honest, but I don't think we should be too restrictive.

What I have not done before is network address translation but preserving the port numbers. So, if the private side of the box is 192.168.1.0/24 and the public side of the box should make the private side look like 158.153.1.0/24, how is this done in Linux. E.g. Private PC on 192.168.1.1 sends a packet with source address 192.168.1.1, source port 12000, destination port 80. Public side sees a session coming from 158.152.1.1 source port 12000, destination port 80. Private PC on 192.168.1.2 sends a packet with source address 192.168.1.2, source port 12000, destination port 80. Public side sees a session coming from 158.152.1.2 source port 12000, destination port 80. etc. for each PC on the private network. As you can see, only the IP address is getting translated.

I want to buy a floppy disk drive (or maybe two or three if they're cheap enough), but they don't even have to work let alone be new. For this reason I don't want to go to PC and buy a new one for a tenner, I'm after second hand or worse for tuppence. Are there any electrical stores in Southampton that might sell 555 timer chips? (http://en.wikipedia.org/wiki/555_timer_IC) I suppose Maplins if I'm lucky, are there any other electrical shops around town? Many thanks all for your time and help, it is appreciated. -- James. http://www.jamesbensley.co.cc/ -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

What ever method you approach to this, you're going to get half baked results as its not fully supported. A better idea IMO would be to buy a BluRay player!

Re: [Hampshire] Slightly OT - Firewall Server
On 7 September 2011 18:30, Rob Malpass li...@getiton.myzen.co.uk wrote: Hi all A simple question: What is a firewall server? I've not heard of this term before. Is it: a) A pretty low spec server that's not got much processing power beyond that required to run ipcop or something similar? b) Something else I anticipate it will have more than one NIC but if I was looking for a really low spec server (or a few of them of identical physical dimensions) as I am at the moment, what's to stop me buying [1]? It can be A or B in some ways. Typically A; what you are referring to are often low spec boxes (when compared to number crunching servers for example) [1]. However, these days you can get boxes with so much functionality, the only thing they don't do is the dishes; so they can be something else. It depends if by A you mean just basic ACL rule checking or firewalls with integrated IDS, IDP, DPI, ACLs, VPN termination, HTTP(S)/SMTP/IMAP/POP filtering, instant messaging monitoring/filtring (the list goes on)... If you want to roll your own, and you're knew to this check out pfSense 2, its a custominsed BSD install with a WebGUI through which you manage everything. [2]. [1] There are high spec firewalls as well with ASIC etc. Depending on the set up, high volume firewalls have to monitor thousands of concurrent flows, each for thousands of possible pattern matches, without hindering the throughput.

It says that they are not so arrogant as to presume that an unexpected intrusion can be put right just by restoring the service that has shown itself to be insecure... Most DR would hope to get some sort of service back online within 48 hours. It would be a simple matter to get the same service back up within 48 hours - and then someone will break in through exactly the same security hole. The kernel.org maintainers have got it right - understand the problem before pretending it has been fixed. And more importantly than that, millions of people world wide use the kernel code provided there; all that code needs to be checked in case its been altered in some way. -- James. http://www.jamesbensley.co.cc/ -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --
Re: [Hampshire] DDoS survival strategies
Hi Damian, I like your script for pulling out IPs and counting their entries, works just fine on my dev machine, but I don't see how it could be practically used. Looking at the number of times alone one IP has accesses your site is not a good measurement of being DDoS'ed. It just means someone loves your site. I guess it would be obvious if you have say 1000 hits a day total aggregate on average, and you see one single IP access your site 10,000 in the last ten minutes. Before that can happen though you need to add some date functionality in there otherwise the data is meaningless; you have nothing to reference it against, presumably it needs to be at least 'hits per IP over X time period'. Also, I think if your script passed those IPs to iptables as rules that would be awesome! In fact now that I think about it, maybe you could just do this all in IP tables without a script? /sbin/iptables -N HTTPHITS /sbin/iptables -A HTTPHITS -p tcp -m state --state NEW -m tcp --dport 80 -m recent --set --name HTTP --rsource /sbin/iptables -A HTTPHITS -p tcp -m state --state NEW -m tcp --dport 80 -m recent --update --seconds 180 --hitcount 1000 --name HTTP --rsource -j DROP So these rules will essentials drop traffic from an IP that has already made 1000 requests to your server within the last 3 minutes, something like that perhaps? Like your script though, just going on numbers of hits is a dangerous method. If you run high traffic sites though (or low for that matter) the first give away for the (D)DoS is (IMO) going to be (as you would expect from a DoS) the sudden peak in number of open connections, CPU utilisation, memory utilisation, increased network throughput, increased drive I/O. A sudden spike in your load anywhere in fact, such as on your DB servers, or front end servers, load balancers, edge routers blah blah blah. So, graph everything all the time, set up alerts and you should be OK (YMMV!). Regarding your other points. My first port of call would be my upstream connectivity provider, I would get them to black whole the traffic, if you aren't dropping it with automatic IP tables rules that is :) Most providers support communities when you directly peer with them through BGP and have black-wholing communities etc so there is scope to work with your upstream provider. What general growing problems do systems engineers face in the future? Regarding what exactly? Security, or infrastructure, or both? Will IPv6reduce DDoS attack success or enhance the attacker's tool kits? I don't think IPv6 gives any extra powers to those wishing to DoS, it just puts a different spin on it. For example, IP blacklists and firewall tables are going to become massive! Manufacturers are going to be under pressure to forward at 100Mbps, 1Gbps, 10Gbps and 100Gbps with giant caching tables/routing tables. For your firewall devices, comparing a list of millions of blocked IPv6 addresses against every flow passing through in a few milliseconds to maintain a high throughout rate is going to require some seriously fast technology! Can we reassure customers that they will not lose business to DDoS without investing large amounts capital in security technologies? Yes and no :) IMO, very careful and meticulous planning and mitigation can prevent a high percentage of (D)DoS attacks or stamp them out very quickly, but if the opposition has lots of capital or infrastructure at their disposal there can be only one winner! What do you think? - is DDoS a global or local problem; or both? Do you mean local as internal to your network? So attacks sourced from your local network vs globally, then globally IMO.

Hi Luggers, I'm new to HantsLUG and am thinking of showing my face tomorrow if I can, to say hello. Just wanted to introduce me self and see what goes on here. I'm a happy member of ALUG (Anglian-LUG) as Norwich is my home town, but I have 10 fingers and 10 toes (including thumbs etc) so don't worry. I'm a network engineer recently moved to Southampton. I thoroughly enjoyed attending ALUG meetings as they are in a pub, so it was always a good social time and people always brought kit to dazzle you after a few cold ones which is fun (normally Arduinos) :D So what's HantsLUG like, do you guys ever have socials and go to the pub? Or pub after a meeting? [1] Also where is the Red Hat Farnborough location of the meet tomorrow as the link on the wiki is broken? Thanks for reading, and hopefully see you soon! [1] At this point I think I may be giving the wrong impression like I'm a regular boozer, I'm not! I just find the pub to have a good laid back atmosphere were people aren't afraid to voice crazy ideas they have about running Linux on calculator and running with said idea :D -- James. http://www.jamesbensley.co.cc/ -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --
