This is a geeky post which is unlikely to be interesting or even understandable to anyone other than those familiar with Debian Linux or similar systems.
I managed to trash my Debian system just recently. The /root partition was too small. I used gparted to increase it but made the mistake of gparted’ing the / EFI partition while increasing the size of the /root partition. My Debian system has been great for years and I’m out of practice installing Linux. My excuse – as poor as it is – is that / is traditionally the root partition. The Linux filesystem has changed and now there’s a /root partition and / is the /boot partition.
I tried to the repair the / EFI partition without success. The reEFI tools wouldn’t work for me. I reinstalled Debian many times while keeping my /home partition. I was using Debian install in expert mode.
I found that xfce4 was virtually useless after the Debian install. I suppose that it may be because I’m keeping my /home partition upsetting the settings. [2/11/16 I’ll try getting rid of anything relevant. [2/11 later. It was the previous config messing it up)) All applications are obscuring the start menu and the minimise, maximise, close window **adornments** are missing. Audio is simply not working after a Debian 8 install – what’s that about? It should just work, I tried fixing it but I shouldn’t have to. Debian used to install so well. It’s a 2011 A64 system [2/11/16 Amd64) , mainstream now and really should be no problem.
Years ago (95-05) gnome was fine if a bit heavy and slow. I can’t stand it now even in classic mode. The default gnome is unbearable. KDE is so slow and a real pain to achieve anything. Audio still not working. [2/11/16 soundcard not recognised appears to be a problem with Deb8 install. I tried to get hold of Deb7 install because it upgrades fine … )
[ed: After reinstalling Debian on one occasion apt was warning that installations were unverified. apt’s verification system was compromised.)
I then tried to netinstall Debian. I suppose this is the real reason of this post. Fetching a netinstall image from Debian.org I noticed that I was downloading from another not Debian.org site. I do anyway check integrity and the netinstall image sha256sum was wrong. I found it difficult to find the sha256sum on the Debian site which was a bit of a pain.
[ed: Were the spooks onto me?)
I’m likely to install OpenBSD as a desktop.
Simple security suggestions: Check integrity of install images, use long passwords, use a firewall, check what services are visible using nmap.
[4/11/16 Looks like audio was fine and not working due to a silly mistake by me.]
[5/2/15 I may have been mistaken about the running inside virtualization and that is probably normal livecd messages. There is still something amiss with the different ps axu(s) – it does at least make me very suspicious since I can’t think of any reason why that would happen other than nasty. I’m also surprised that this system is so difficult to boot into OpenBSD. You can’t be too paranoid, or can you?]
I’ve got an AMD64 thin client as a gateway / router that also runs a tor relay. It usually runs dnsmasq but has been running the more conventional dhcpd and named recently. It uses a small camera-style flash card as a hard drive running current and patched OpenBSD. My internal network connects to this through a switch. I run firewalls on all machines – pf on this of course and usually arno-iptables-firewall on debian boxes. This box currently has an uptime of over 59 days.
Just recently I’ve had a hard drive fail on my desktop debian machine. I was very surprised at this since it’s very low mileage and being debian linux it hardly ever gets powered down. It appeared to have many and increasing terrible errors that also seemed to jump about whenever I tried e2fscking them. I can’t help but suspect that GCHQ contributed to the apparent demise of this drive.
My new replacement drive arrived yesterday and I had decided to install an OpenBSD xfce desktop. None of the OpenBSD install cds were recognised. What’s going on here?
That can’t be right – that tor only appears in the second and subsequent ps axu(s). Having huge difficulty i.e. it is impossible, to install OpenBSD to my desktop machine. They’re pwned.
OpenBSD doesn’t install under a Linux virualization ‘wrapper’. Linux runs under Linux virtualization, OpenBSD won’t – at least not under this virtualization.
“NET: Registered protocol family 17
mpls_gso: MPLS GSO support” it reads – it’s embedded Linux.
It appears to be a very small wrapper in IPv6 coming from the OpenBSD router / gateway. My laptop starts complaining that BIOS has been changed – not seen that message before. The tor router relay is stopped pretty sharpish.
GCHQ? Well my connection to my ISP is to their ‘audit’ machine. I guess that means GCHQ. My close friend’s car was hours late back from it’s first service – shouldn’t the first service only be oil and filter, a half hour job? After that it was clear that cops could hear everything said in that car and were often waiting for us to arrive. A friend who I was once close to had the ‘Water Board’ round to check his taps. He remarked that she was well-presented. I’ve noticed that local ‘Scientific Investigation’ policewomen are well-presented. Oh, and we had a deep cover spy at our anti-casualisation group meetings. He was also at a pre-G8 2005 meeting. I think that he was Met, very interested in me and an apparent dirty, hairy anarchist cop.
I was using a password 29 characters long. My guess is that they used my mobile to map my keyboard – different characters sound different and there are differences in the time I take to reach them. Or they could have watched (spied) through the window.
I don’t know if they wanted me to find this or not. I met someone from GCHQ in the Bunch of Grapes one Friday afternoon many years ago. It’s their job, it’s what they do.
I watched this a few hours earlier. You may get lost after the first 10 minutes or so. 30 to 37 minutes or so is good for politicians.
but while I’m listening to this I want to explain a far greater danger than terrorism that I face almost daily because you see, I am a cyclist.
Yesterday I was almost mown down by a motorist that was on the wrong side of the road and almost mowed me down. He had not seen me because he was texting.
Motorists on mobile phones are lethal to cyclists – a far greater danger than any supposed attacks by ‘terrorists’. I can attest that there is a far greater danger to people – pedestrians, cyclists and motorcyclists – than terrorism. We need a sense of proportion, to be measured and to asses issues. As a cyclist, I am telling you it is far more dangerous than any fake manufactured, terrorism nonsense. I accept that there are a very few terrorists – usually insane. How can they be anything other than insane? But, they are caught up in the terrorist narrative. Cycling and being a pedestrian is far more dangerous.
Where is the international campaign against motorists using mobile phones? Surely NASA, GCHQ can catch these ‘t*******ts’? Don’t they cause terror to ordinary people and kill indiscriminitely? Actually, yes they do. And far more than this terrorism BS.
There are very few terrorist. Yes they should be pursued. There is fake, manufactured terrorism which is still terrorism pursued by nation-states and criminal cabals. There are also a few poor sods caught up in the terrorism narrative but let’s get it in perspective.
Indiscriminite drones. Stop it.
Ok, er, cycling is nothing compared to rockets from a drone. It’s much the same that it’s totally undeserved but I reckon a drone is far more lethal
– he’s talking about speed limits now
struck by lightening
I suggest that you watch the Greenwald vid. still long to go – talking about inscenity now
Talking about terrorism defined as what Muslims do. We had this in Uk recently with the car driven into council offices up North which then exploded. Strangely enough that wasn’t a car bomb and was reported on the news as most definitely not terrorism …
Intermission: I take advantage of this intermission to point out out that I do magick: that I have converted water into wine with the assistance of fruit, sugar and yeast. I made Melomel for the first time this year and I think that it may have been the first medicine (Meddygon Myddfai). Untreated, unadulterated honey and currant fruits worked really well. It was like a universal medicine – anything that was wrong with you it cured. I believe that it is possible to keep bees without exploiting them.
OK, intermission over.
22/1/15 2.40am At least they know that I’m not into CP. I wish that they would go for the ones that are (and more). Actually, I want them to go for the people that abuse children. My understanding of GCHQ’s purpose is that it’s outside their remit. I think that GCHQ is military and concerned with defence. Can we change that so that they catch paedos?
OpenBSD is widely regarded as the most secure operating system. Today is the release date of the latest release OpenBSD 5.4. You’ll need to give it a few hours because it’s not yet 1/11 in Canada.
OpenBSD is secure because it is continually security audited. It is absolutely ideal for firewall/routers because of it’s advanced pf packet filter. It’s best suited for servers but also performs well on desktops and multimedia machines.
Other geeky things I’ve been doing lately
Learning C programming properly. C is all about pointers and indirection. It seems to be taught totally the wrong way. Pointers are key and all else follows …
I recapped a motherboard. You don’t need a new machine nowadays and I was pleased to revive a machine for a friend’s parents. It’s good to save a computer from the skip. I solder badly because I don’t do it often enough but I obviously solder well enough.
I replaced a Sempron LE-1150 with a really fast Athlon X2. Now it rocks.
[11/11/13 I’ve been trying to learn Drupal 7. Drupal is a Content Managment System (CMS) which also claims to be a CMS framework. A CMS is used to build websites and Drupal is used to build many of the most complex and advanced websites. As the diagram shows, Drupal is difficult to grok. My experience is that it’s counterintuitive and opposed to many of the principles of programming e.g. the use of global variables. But then it’s not programming of course – it’s an application for developing websites.
I did try Joomla and WordPress but it looks like Drupal is what I need to build the websites I want. I think it may be that you just have to learn the Drupal way. Just lately I’ve been doing some maintenance to this blog and realised that WordPress produces an awful lot of dead links which are no good to anyone. I’m thinking of converting this blog to Drupal soon and get some practice in.
There’s some weirdness about this post – not allowing me to edit it as I normally would. I’ve had to use a different browser because it simply appeared totally blank in the browser I normally use but yet it appears published fine. Weird.]
[9/12/13 I’ve been repairing analogue radios just recently. It’s surprising what some contact cleaner, compressed air and a vacuum cleaner can achieve. I still need to repair my favourite radio which was second-hand and well used when I got it about 1999. It will need some soldering but some radios are special.]
Some geeky tips
Use strong passwords. I particularly like long passwords because I know about brute-forcing.
Get a real operating system. Linux livecds can help.
[More geeky tips. This could go on and on.
Firewall. Firewall on all interfaces especially on laptops and mobile devices. Lock it down.
Wireless should be considered insecure.
[6/11/13 The Guardian has published a Guide to Tor. The latest Tor browser bundle should be used and care should be taken. People have been caught-out accessing web-based email by not appreciating how it works. It should not be used for anything that divulges personal info and there’s not really much point in watching Youtube through Tor. If you’re in a repressive country it’s worth using. Basically, it hides what you’re looking at. [edit: It’s likely to get past broad political internet censorship. ]
If you have geek competence and spare resources please consider running a Tor relay as I do. There are certain dangers involved in running an exit node (relay) which do not apply to intermediate nodes.]
… and here are the regulations from the ILETS / ENFOPOL affair of the 90s. These regulations are demands made by law enforcement authorities of the capabilities needed to infiltrate communications. Essentially, these law enforcement demands are design requirements for communication systems. You will notice that these requirements date from the mid 1990s. It’s probably safe to assume that they have been implemented by now. [Later edit: These regulations were intended particularly at mobile devices: phones at that time e.g. the reference to location. These regulations are bound to have been updated in the same culture of secrecy for technological developments since.]
This section presents the Requirements of law enforcement agencies relating to the lawful interception of telecommunications. These requirements are subject to national law and should be interpreted in accordance with applicable national policies. Terms are defined in the attached glossary.
1.Law enforcement agencies require access to the entire telecommunications transmitted, or caused to be transmitted, to and from the number or other identifier of the target service used by the interception subject. Law enforcement agencies also require access to the call-associated data that are generated to process the call.
1.1.Law enforcement agencies require access to all interception subjects operating temporarily or permanently within a telecommunications system.
1.2.Law enforcement agencies require access in cases where the interception subject may be using features to divert calls to other telecommunications services or terminal equipment, including calls that traverse more than one network or are processed by more than one network operator/service provider before completing.
1.3.Law enforcement agencies require that the telecommunications to and from a target service be provided to the exclusion of any telecommunications that do not fall within the scope of the interception authorization.
1.4.Law enforcement agencies require access to call associated data such as:
1.4.1.signalling of access ready status;
1.4.2.called party number for outgoing connections even if there is no successful connection established;
1.4.3.calling party number for incoming connections even if there is no successful connection established;
1.4.4.all signals emitted by the target, including post-connection dialled signals emitted to activate features such as conference calling and call transfer;
1.4.5.beginning, end and duration of the connection;
1.4.6.actual destination and intermediate directory numbers if call has been diverted.
1.5.Law enforcement agencies require information on the most accurate geographical location known to the network for mobile subscribers.
1.6.Law enforcement agencies require data on the specific services used by the interception subject and the technical parameters for those types of communication.
2.Law enforcement agencies require a real-time, fulltime monitoring capability for the interception of telecommunications. Call associated data should also be provided in real-time. If call associated data cannot be made available in real time, law enforcement agencies require the data to be available as soon as possible upon call termination.
3.Law enforcement agencies require network operators/service providers to provide one or several interfaces from which the intercepted communications can be transmitted to the law enforcement monitoring facility. These interfaces have to be commonly agreed on by the interception authorities and the network operators/service providers. Other issues associated with these interfaces will be handled according to accepted practices in individual countries.
3.1.Law enforcement agencies require network operators/service providers to provide call associated data and call content from the target service in a way that allows for the accurate correlation of call associated data with call content.
3.2.Law enforcement agencies require that the format for transmitting the intercepted communications to the monitoring facility be a generally available format. This format will be agreed upon on an individual country basis.
3.3.If network operators/service providers initiate encoding, compression or encryption of telecommunications traffic, law enforcement agencies require the network operators/service providers to provide intercepted communications en clair.
3.4.Law enforcement agencies require network operators/service providers to be able to transmit the intercepted communications to the law enforcement monitoring facility via fixed or switched connections.
3.5.Law enforcement agencies require that the transmission of the intercepted communications to the monitoring facility meet applicable security requirements.
4.Law enforcement agencies require interceptions to be implemented so that neither the interception target nor any other unauthorized person is aware of any changes made to fulfil the interception order. In particular, the operation of the target service must appear unchanged to the interception subject.
5.Law enforcement agencies require the interception to be designed and implemented to preclude unauthorized or improper use and to safeguard the information related to the interception.
5.1.Law enforcement agencies require network operators/service providers to protect information on which and how many interceptions are being or have been performed, and not disclose information on how interceptions are carried out.
5.2.Law enforcement agencies require network operators/service providers to ensure that intercepted communications are only transmitted to the monitoring agency specified in the interception authorization.
5.3.According to national regulations, network operators/service providers could be obliged to maintain an adequately protected record of activations of interceptions.
6.Based on a lawful inquiry and before implementation of the interception, law enforcement agencies require: (1) the interception subject’s identity, service number or other distinctive identifier; (2) information on the services and features of the telecommunications system used by the interception subject and delivered by network operators/service providers; and (3) information on the technical parameters of the transmission to the law enforcement monitoring facility.
7.During the interception, law enforcement agencies may require information and/or assistance from the network operators/service providers to ensure that the communications acquired at the interception interface are those communications associated with the target service. The type of information and/or assistance required will vary according to the accepted practices in individual countries.
8.Law enforcement agencies require network operators/service providers to make provisions for implementing a number of simultaneous intercepts. Multiple interceptions may be required for a single target service to allow monitoring by more than one law enforcement agency. In this case, network operators/service providers should take precautions to safeguard the identities of the monitoring agencies and ensure the confidentiality of the investigations. The maximum number of simultaneous interceptions for a given subscriber population will be in accordance with national requirements.
9.Law enforcement agencies require network operators/service providers to implement interceptions as quickly as possible (in urgent cases within a few hours or minutes). The response requirements of law enforcement agencies will vary by country and by the type of target service to be intercepted.
10.For the duration of the interception, law enforcement agencies require that the reliability of the services supporting the interception at least equals the reliability of the target services provided to the interception subject. Law enforcement agencies require the quality of service of the intercepted transmissions forwarded to the monitoring facility to comply with the performance standards of the network operators/service providers.
22/7/14 My stats show that this is the most popular post – probably because of the ILETS / ENFOPOL quote above.
Got a spares or repair box off eBay cheap and swaped the processor. It rocks – quad core, 2T hard drive and I only ever use a small part of the memory.
Learning django at the moment and hoping to build a site using it soon. Python is good.
Everything wireless strikes me as fantastically insecure. Normal computer users are going to be vulnerable to evil twins at public hotspots. What about wireless keyboards? That’s a keyboard transmitting what keys are pressed. I don’t know but would doubt that encryption is used.
