How to enable WiFi from cammand line on eeePc?
by Chris G 03 Oct '11

03 Oct '11

I have an Asus eeePc 701 running Ubuntu 10.04, no GUI just the base installation plus a few bits I needed. We now have WiFi available on the boat (where the eeePc is) and so I want to use it from the eeePc - does anyone know how to do it? The eeePC sees the Wifi as an ifconfig returns some information about it, what command line tools etc. do I need to configure it? The WiFi is pretty standard with "WPA & WPA2 Personal" security. -- Chris Green

Need some router/WiFi/routing help and advice
by Chris G 26 Sep '11

26 Sep '11

I need to 'rearrange' the internet connection on our boat. We used to have a connection via a 3G router with a Mobistar (Belgian) SIM in it and everything on the boat (two PCs, printer, VOIP base station) just plugged into the router. It was flakey at times because we didn't have a good signal, but it worked. However we are now permanently in France and our long term mooring has WiFi available (whoopee!) This rather spoils my nice simple setup and I need some advice to work out how to rejig things. The trouble is that neither the printer nor the VOIP base station can do WiFi so I need to have a switch at least to interconnect things. However even that isn't straightforward (at least not to me!). What's needed is:- Local (i.e. LAN) connection between PCs and printer, can be provided by a switch or router but needs to be routed correctly so PCs use the WiFi for everythng except the printer. At present I have to disconnect WiFi and connect wired LAN to print and then vice versa to use the internet. I need to connect the VOIP base station (wired ethernet only) to the WiFi somehow so we can use the phone. The ideal solution would be if I can persuade the 3G router (which does have wireless) to connect to the WiFi here and then provide hard wired services to PCs, printer and VOIP. Is this a normal sort of thing to be able to do? The router does have something about WiFi relay in 'Lazy', 'Bridged' and another mode, should I be looking at these? -- Chris Green

usb to parallel printer converter
by Peter Alcibiades 24 Sep '11

24 Sep '11

Does anyone have any idea for this? I have a star receipt printer with a parallel interface and no linux drivers. So I am printing to it using lp and just sending raw text to the device itself. The command in question, which works just fine, is: lp -d star temprint.txt In the same way, I send the hex characters to make it cut the receipt and also to open the cash drawer. I say it works fine, it has one slight issue which we can live with, that being that if the printer goes offline, all the print requests queue up and print out in a batch when it comes back. However this being an industrial strength receipt printer, its something we can live with, it hardly ever happens. Leaving that aside.... I set up the printer in CUPS with the name of star, and addressed as parallel:/dev/lp0 Now comes the problem. Parellel interfaces having gone the way of the dodo, the new computer I'm seeking to use only has a usb port. So I got a usb to parallel converter cable. I have played with this by stopping cups, then editing the /etc/cups/printers.conf file. I can't get it to work. Supposedly from the gentoo wiki, which is usually very helpful, you should address it as parallel:/dev/usb/lp0 On the grounds that linux still thinks its dealing with a parallel port. Makes no sense to me, but I tried it, and no luck. The cable itself is recognised and visible if you do lsusb. Also, I know it works fine as cable because I can connect another printer with a parallel port for which I do have drivers, and successfully print a test page on it over that cable. I must be doing something obvious wrong, but what? How do you address the usb port directly and just send it a stream of text, as in my present setup? Is there a way? Peter

Restarting Firefox from the commandline
by Mark Rogers 23 Sep '11

23 Sep '11

I have an Ubuntu box which I can access remotely via SSH. It is primarily a server but has a GUI with Firefox running on it for people on site to access the web interface that the server provides. Firefox, being Firefox, sucks up memory the longer it's running. So I'd like a way to force it to restart via my SSH connection, and assuming I'm happy with the results probably via a cron-job every night. I can obviously "kill" it, but I'm not sure how I then restart it given that I'm not running from within the GUI environment myself; also, I don't want it to start up offering to restore tabs from a crashed session, I just want it to go to it's configured home page. Suggestions? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Partitioning Laptop
by Richard Parsons 20 Sep '11

20 Sep '11

Hi, I've recently bought a Compaq laptop. It currently has Windows 7 installed and I want to dual boot with Ubuntu. Unfortunately, Compaq have already partitioned the hard disk into four partitions. The largest partition, which is 480GB is the second. If I begin the installer, and resize the second partition to create free space, then I'm told that it is "unuseable". I believe that the extra partitions are for recovery etc. So what can I do? Is there a way of getting Ubuntu installed without disturbing the contents of the partitions already setup? Thanks in advance Richard

Running CUPS as normal user
by Dan 16 Sep '11

16 Sep '11

Dear All, On my Gentoo system, /usr/sbin/cupsd has permissions -r-x------ i.e. it can't be run (nor even read) as a normal user. Does anyone know why, please? Is it safe just to chmod the file then run it as a normal user? (Background: my new printer, an Epson SX525WD, needs proprietary drivers - and I like to run proprietary software only as a special, low-privileged user.) Thanks -- Regards, Dan

I half expect someone to say how easy this is but I'm trying to join three photos together to form one jpg file. Easy to do in OO. In GIMP, I have no idea and the tutorial page doesn't seem to say anything on the topic. Help. Bev.

See message headers or the web site above! Yes, they are not bad. I have bought from them in the past, and their stuff arrives promply, properly packed, and the price is reasonable. The available stock fluctuates wildly as you would expect. I bought a laptop for a charity a few years back, we put Mandriva on it, and its going strong today. I see they have quite a stock of laptops now. Peter
