I anticipated that the IT manager would come back with a suggested card and wanted to see if I could propose something Linux usable- if you are right Wayne it seems more likely that the IT manager will come back and say that the whole idea is flawed even for MS machines. If a speaker turns up at 12pm wanting to access the internet during his talk, catch up on a few emails in the common room afterwards then be on a train at 5pm, we don't want to be poking around in his wireless card configuration trying to disable the built in one and enable our usb one. Apart from the hassle a visitor might feel justifiably annoyed if they then get back home and have problems getting their own wireless connections working again. I appreciate the info regarding the BT and Norwich networks. I think though that we are keen to offer the courtesy of a free connection to our guests and the Norwich city network has an uncertain future. Plus, how good is indoors reception with these? Looks like I should bring my own laptop in and try all the options with both Ubuntu and XP. Then if necessary our school can do what it can to push for a streamlining of the visitor registration process. I don't want to over push the linux thing at UEA as I get the feeling that attitudes to FOS in general vary considerably among our technical people here and I don't want to come across as too much of a trouble maker. I'm especially wary as someone with low technical knowledge- but you have given me some useful pointers to do what little I can here.

usb wireless card for visitors
by Rob Grant 19 Jun '07

19 Jun '07

Visitors to UEA need to get their network cards registered in order to access our network. As a more convenient alternative, the technical support manager here suggested that our school buy two or three usb wireless cards which can be pre-registered and loaned to visitors. Obviously, I'd like to make sure that whatever we get will have a good chance of working for any visitors who arrive with Linux laptops. Hence, any ideas on either of these would be appreciated. i) suggestions for a usb wireless card that should plug and play with Linux, Macs and Windows. Physical robustness probably a help too. ii) or is this whole idea a bad one? Apologies if this 'which wireless card?' thing has been rather done to death here recently. I can't recall anything specifically usb and mac/win interoperable though. Thanks, Rob Rob Grant Lecturer in Development Economics School of Development Studies University of East Anglia NR4 7TJ +44(0)1603592324 r.grant(a)uea.ac.uk

Tried what you suggested Adam, and got 'command not found' for aptitude install apt. Also had 'command not found' for sudo aptitude install apt. In fact I also tried commands ls, man, sudo, and they all returned 'command not found'. Does this mean that all (most) of my commands are unavailable? About a week ago I went through the update procedure. I started with Dapper 6.06 (from live CD), updated to Edgy 6.10, then updated to Feisty 7.04. Things worked perfectly until last weekend when I tried to boot up linux and got this result. Would I presume that the live CD 6.06 would not now be of any use since I am 2 upgrades up? I've alo tried recover mode at Grub but doesn't work either - same results. Is there such a thing as a rescue disk that will repair my OS without losing my work? Fortunately I am dual booting with Win98 (wash my mouth out), but it is a right pain rebooting backwards and forwards. I look forward to any suggestions - elc > > It gets to a point > > "the program 'apt-get' is currently not installed.

Various people at ALUG are trying to help me with my problem, and I thank them for their help in trying to get me back into Kubuntu. Someone asked if anything unusual has occured in the recent past to maybe cause my current situation. Only one thing comes to mind, is that when I first enter my password at the beginning of a session the first character depressed on my keyboard is not registered. There is no fault with my keyboard, - I have checked this. When I have tried to test my OS with your suggestions during the past week, I have got to a terminal prompt without any imput from me and at the first occassion of me entering a character the character is not registered, the second character (which is a repeat of the first) is registered. Do I have a gremlin here? Is it a cause or a symptom of my problem? On another thought, can I re-install my OS on top of my existing (non-working) OS to resolve my problem, as I can do with Windows? elc

Did as suggested 'echo $PATH' gave /lib/init:/sbin:/bin and 'ls' just returns me to desktop cursor and '/usr/bin/apt-get' gives me a fast scroll which I was not able to record and 'cd /bin' gives 'root@elc-desktop:/bin#_' and 'cd/usr/sbin' gives 'root@elc-desktop:/usr/sbin#' Wayne Stallwood wrote > Given that it worked for a while after the upgrade I am guessin that > either your system volumes is not available or your path is wrong. > > > What is the output of - > echo $PATH > > (case sensitive) > > does /bin/ls work rather than ls on it's own ? > or /usr/bin/apt-get ? > > Can you 'cd' to /bin or /usr/sbin ? >

At command line I did 'set' and this gave a long listing which might have scrolled off the top of screen.
