stumbling around with sigil...
by Peter Alcibiades 21 Apr '13

21 Apr '13

OK, finally solved the problem with QT5, though without being really clear what worked or why. It did finally compile and installed itself politely in /opt. Now there is another puzzle. The problem was to install and run sigil. Which is a very nice package indeed if you want to edit epub books.Very nice. Unfortunately you have to compile it from source. They do not do binaries, and if they have as hard a time as me with it, I can understand why. The problem is that entering the command sigil in a terminal produces an error to the effect that libQt5 widgets is not found. However, the binary is installed in my home directory in a sigil folder, and if I execute this binary it works just fine. If I look in the /opt sigil directory, qt5widgets is indeed there. So how do I change the command so that it calls the binary that works? There must be a file someplace that has all these commands in it, but where? Al

Re: [ALUG] Looking up IP address via DNS

I have managed to solve this in two ways, in case anyone is interested. First: $ dig @8.8.8.8 192.168.1.1 +short $ dig @192.168.100.5 192.168.1.1 +short 192.168.1.1 It turns out that Google's DNS doesn't give an answer when queried for an IP address, but my own office DNS (dnsmasq) does. So controlling the DNS server gives me a solution. Secondly though: I found a way to bypass the braindead behaviour in the unit, and although it's messy it works, so none of the rest of this matters any more! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Looking up IP address via DNS
by Mark Rogers 18 Apr '13

18 Apr '13

I'm working with a brain dead system, so bear with me... I need a way to do a DNS lookup of an IP address that returns the IP address. I can control the DNS server, and/or possibly apply a suffix to the IP address. The reason is that I have an industrial unit that will accept a hostname (for FTP purposes) but if I enter an IP address it fails, and this appears to be because its DNS lookup of that address is failing. The unit should have Internet access and I can set the DNS server to whatever I like, so one option would may to run my own DNS server that when queried for "192.168.1.1" returns the IP address "192.168.1.1". That pre-supposes that the unit isn't already detecting that "192.168.1.1" is an IP address, not doing a DNS lookup, but then failing for some other reason (where it does not fail if I use a name which looks up to that IP). A "better" solution is probably to apply a suffix, so instead of entering "192.168.1.1" I enter "192.168.1.1.example.com" [1] where the DNS for "example.com" will return the IP address. That way I know that the unit will be forced to go through a DNS lookup and is more likely to just work. I'd just need some guidance on setting up BIND or some other DNS to achieve this. Any ideas? The "best" option would be to get the manufacturer to fix their product but it turns out that the best options aren't always available :-( [1] Just for clarity: the user enters the IP address and I have no control over what address they'll enter. In my code I then detect that it's an IP address rather than a hostname (probably just checking whether the last character is numeric would suffice), and appending ".example.com" before passing to the FTP handling code. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

QT5 compile errors
by Peter Alcibiades 17 Apr '13

17 Apr '13

This is the error I am getting:- Could not find a package configuration file provided by "Qt5Core" with any of the following names: Qt5CoreConfig.cmake qt5core-config.cmake Add the installation prefix of "Qt5Core" to CMAKE_PREFIX_PATH or set "Qt5Core_DIR" to a directory containing one of the above files. If "Qt5Core" provides a separate development package or SDK, be sure it has been installed. I am trying to compile and install Sigil from source. Anyone know specifically how to do what its asking for? Like what to put in what file? Al

USB 2.0 to ethernet adaptors
by mick 11 Apr '13

11 Apr '13

Hi all Does anyone have any experience of using USB 2.0 to ethernet adaptors? Ignoring the apparently magical ability to get more than 280 Mbits/s of adaptors advertised as "USB 2.0 to gigabit ethernet", what is the realistic maximum throughput anyone has experienced with such devices, and on what architectures? I am considering options for building a very small, low powered in-line F/W and some of the devices I am looking at only have one ethernet port (but often two or more USB ports). Any and all advice (up to and including "don't be silly, do it properly") happily accepted.

What does group 199528447 mean
by Chris Walker 11 Apr '13

11 Apr '13

Having dutifully followed advice and backed up my NAS drive using rsync, I have formatted the NAS and now want to write the contents of the rynced drive back to the NAS. But it gives me lots of 'Permission Denied' errors. I thought I'd re-created the NAS as it was but that's done through a web browser so I might well have screwed it up but it seems to be working, albeit that I can't now write to it. So once and for all, I'd like to fix the problem so that in the future, I can read and write files to the NAS without experiencing permission errors. I tried to find the cause of this error on google but it only returns one result and that's no help at all. I then looked at the groups configuration GUI on the machine but there are no groups numbered above 500 so how come this one is saying 199528447? If it helps, the user number is the same. So where do I start with trying to fault find this?

Running commands at boot
by Chris Walker 11 Apr '13

11 Apr '13

I run some software called RPCEmu (http://www.marutan.net/rpcemu/) and I want to run networking on it. I've setup networking on the emulator and also on my linux box. But I have to run the commands each time. These are the commands, run as root :- iptables -I FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -t nat -A POSTROUTING --source 172.31.0.0/16 -o eth0 -j MASQUERADE sysctl -w net.ipv4.ip_forward=1 sysctl -w net.ipv4.ip_dynaddr=1 How do I run them each time I switch on the machine so that they're run as root? Any help appreciated.
