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. What is showing on screen is no line starting with PATH= , nearest to it is a line 'verbose= no = path' Ted wrote > On 12-Jun-07 22:31:22, elc wrote: > >> > Tried what you suggested Adam, and got 'command not found' for aptitude >> > install apt. >> > Also had 'command not found' for sudo aptitude install apt >> >> Looks to me as though your PATH is empty, so your shell has >> nowhere to look for the commands. >> >> >From you command line, enter: >> >> set >> >> and look down the resulting list for a line that starts >> with "PATH=...." >> >> If you do not find one, then you have an empty PATH and that >> is the problem.

Did 1) as suggested did '$ which dpkg' and got nothing - just returns to cursor did '$ which wget' and got nothing - just returns to cursor Did 2) '$ wget' and got 'bash: wget: command not found' Didn't do 3), was this reliant on 2) ? you'll need to forgive me I'm a newbie and didn't really understand your instructions, but thanks anyway. > On Tuesday 12 June 2007 23:31:22 elc wrote: > >> > 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'. >> > >> > Your problem may well be disk errors, but in case you just want to get apt > installed (which will be handy for helping to diagnose other problems) try > this.
