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.

Dropbox alternatives, was Re: Diagnosing high X CPU usage

Following a link from OwnCloud's website, I find that OwnDrive.com do a free 1GB account. However, I have looked at OwnCloud (briefly) a long time ago so I thought I'd have another look at it, using my own server to host it. I decided to go with the install from the OpenSuse Build Farm repositories (onto Ubuntu 12.04), since that takes care of updates. However: $ sudo apt-get install owncloud [...] The following extra packages will be installed: autoconf automake autotools-dev binutils cpp cpp-4.6 gcc gcc-4.6 libc-dev-bin libc6-dev libltdl-dev libmpc2 libmpfr4 libquadmath0 libssl-dev libssl-doc libtool linux-libc-dev m4 manpages-dev php-pear php-xml-parser php5-dev php5-sqlite shtool zlib1g-dev That's a lot of dependencies that I wouldn't expect? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

git usage
by Chris Green 04 Apr '13

04 Apr '13

I have lots of scrappy little bash and python scripts that live in ~/bin. I have been trying to keep tabs on them using git but I don't seem to have a good strategy for doing this yet. Should one:- 1 - Have a separate 'development' directory where one mucks around with the scripts and keep that directory under git. Then, when tested copy the script to ~/bin. 2 - Simply put ~/bin under git. The second approach is much easier in some ways and most of the scripts are pretty trivial (but easier to test when in their proper place). ... and/or are there any git commands/tools to help one do this? -- Chris Green

Diagnosing high X CPU usage
by Mark Rogers 04 Apr '13

04 Apr '13

According to "top", /usr/bin/X is using between 30% and 60% of my CPU (and can go higher). this is on an AMD A6-3670 (quad core) system running Kubuntu (13.04 beta), and my new nVidia G210 graphics card with proprietary drivers. I had the same problems with the onboard GPU in 13.04 and 12.10 before it. Eg: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1357 root 20 0 321m 207m 49m R 48.9 1.3 214:58.86 Xorg Why would X CPU be so high, and what can I do about it? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

When and where is the next one? Ah. Do you see any regular attenders? Until my GP gets my beta blockers sorted so that I'm not nearly passing out from time to time, I'm not safe behind the wheel. IIRC, you live near Syleham? That's a bit far to bike. How often do you get into Norwich? I'm sure The Tea House near the bottom of Elm Hill would accept a small parcel. Obviously, I'm not in any hurry. /snip/ >>> Allows equipment with SCART or phono outputs to plug in to a >>> TV or aerial socket Direct channel selection /snip/ >> Thanks - sounds right up my street!

Open/Libre Office and docx

I've been finding that opening MS docx files with Libre Office makes the formatting go ever so slightly awol. Is there another office program I could use that doesn't have this problem? Bev.
