ps. there's no History in Ubuntu Software Center
I know the 'history' command give me a list of the commands I have typed into the Unix terminal.
How do I see the command history for all of the users currently logged onto the system?
I was wondering if there was a script that would run on log in telling me the history of when the server was rebooted or such, along with the last user and motd (which is a roflcopter in my case)
View 8 Replies View Relatedi have been using ubuntu for just over 3 months now and i completely love it. but heres where the problem starts (and please let me know if i am in the right topic) i recently installed ubuntu 10.10 on my roommates computer, the reason being is that the IT department here on college "fixed it" for him, now it wont connect to the internet. it will however connect if we use an ethernet cable from the other laptop to his. his had originally windows xp then got upgraded to vista. i was wondering if there was a way to completely reset the networking wifi card if that might be the problem.
my roommates computer is a DakTech PlaidBook, however i do not know on how to check the system information in the terminal to tell you what wifi card he has and such, all i want is to have internet back on his computer again.
i wanted to know what script i would put where that would tell me the last 5 times the server rebooted whenever i logged on.
View 9 Replies View RelatedOS: Ubuntu 10.4 I performed a routine "apt-get update", which apparently upgraded firefox to 3.6.14. If I start FF from the root account, everything works just fine. However, if I start FF from any normal user account, I get the error message: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem" Running FF from root does not give the error (but then, who runs FF as root?). I looked at link at [URL] And renamed the places.sqlite to places.sqlite.old as instructed. Same error. So I quit FF and completely wiped out the .mozilla folder.
FF dutifully created a new .mozilla folder, then promptly gave me the exact same error message again. This STRONGLY indicates that it is not a permissions issue (besides, I looked at the permissions and everything in the .mozilla folder is owned by the user with at least rwx------ permissions... Now I give up on this version of FF (3.6.14pre (Namoroka)) and apt-get remove it, then issue apt-get install firefox-3.5. It re-installed apt-get install firefox-3.5... (the /etc/apt/sources.list file is attached).

View 3 Replies View RelatedI created some users on my Ubuntu 10.0.4 machine a long time ago (whilst experimenting). Some of these users can login to the system, and others were prevented from login in. I can't remeber which ones can login. I have the following questions:
How do I find out which users may login to the machine? How may I disable an existing user account from login in? How may I re-enable a previously (login) disabled user account so it an login again?
System was fine with :Ubuntu 9.04 (had also installed kde )then....I wanted to try some change to gdm so i downloaded gdm while building it , it asked "PAM" libraries to be installed so i installed PAM ... but ignored the instruction to reinstall SHADOW (library i guess..),Now :on booting system i get login menu but i am not able to login , it says some critical error occured
1) install new copy of UBUNTU and remove old
ps :1) i can log into system through live cd
2) i can use recovery mode boot and log into terminal as root(startx is not working from this terminal..
I've searched these forums as well as Firefox's site, as well as searching on Google Linux but can't find what I'm looking for.In a nutshell, I want to keep a log of my users' browser history so that even if they clear history or set Firefox to not keep history, I can still view a log of what site they have visited.My hope is that I can write a script(although I'm a BASH newb it would be a nice little real-world project for me to attempt) that would keep info such as user,visit date,ip of visited site, just the basics. A great feature would be for the logs to be emailed to me for inspection but that isn't vital if I can navigate to the log myself.
For all I know this is already available somewhere in the log folders I just can't find anything. If it helps I'm running Mint 9 Isadora and Firefox 3.6.12
I want to make sure that the user www-data cannot be used to login on my system (Ubuntu Lucid). How can I find out? - is there a command I can run against this user? (traditionally run by Apache daemon)

View 9 Replies View RelatedI have set up a user to login remotely to our Red Hat 5 server via SSH. A rule in our department firewall enables this user to login from a single static ip address. The ssh port on our server is 22. I am able to login to port 22 from locations within our department firewall. Our administrator says the firewall configuration is unchanged. The remote user had been successful logging in. But now the remote user gets a Connection Timed Out message, before being asked to authenticate by the server.
I regenerated security keys, but the remote user still gets the connection timed out message. (I can login locally with the new keys). I suspect either a firewall or an authentication problem--inclining a firewall problem. Am I correct? Is there a Linux command to check whether port 22 is available or blocked, prior even to authentication, for login from the user's remote location?
it has been a year since I've started using Ubuntu linux, and for being calm that everything is working properly, I would like to do a full system check. The only option I've found is on System=> Administration=> System Testing, but this wasn't what I was searching for (mainly because I don't know what is written there- I don't know enough for running this option). Is there something else I can do? maybe something through Terminal?I want to run such a check also because the system sometimes work slowly, and maybe something went wrong...

I've been stupid, and used kleansweep, which deleted a load of files and in the process killed everything. When I boot I get "file system check failed". Then it gives me a command prompt. I really don't want to have to reinstall ubuntu as I have a lot of stuff installed on it.
View 9 Replies View RelatedI have recently noticed that my HDD fsck during boot up (generally done after 30 mounts) is always skipped. A file system check has never happened. I don't remember if this is the case ever since I upgraded to Lucid or was it after I tweaked some settings.I am a learner who keeps tweaking some minor settings, so I am not sure if I have screwed up something.At boot I get the following message:
Code:

I have a Hp Netbook, and my friend installed Ubuntu to my computer. Everything was going fine, until one day my battery died while I was searching the web. I turned it back on and It started checking files and then it took me to a black screen with white letters saying "File System check failed".
View 3 Replies View RelatedA non techie friend has helped an even less techie friend by contacting me by email to discuss an ailing laptop. A few emails were exchanged, with more details, and it was not looking good because it seemed that suddenly the CD drive was not responding, nor any USB devices, the wireless icon was gone, but Ubuntu still seemed to work (for now), with wired ethernet also working. I was struggling to think of what could be done, with the favourite routes of Live CD and Live USB apparently gone.
After a few more hours - another email: 'It's now working! After so many reboots it checked disc for errors and repaired itself! Is there some way of doing that when needed anyway?'I see there is 'Disk Utility', and this would presumably fit the bill, but how does it do checks and repair when the damaged file system is being run, and is currently *mounted*? I thought utilities like fsck(?) could only be run on unmounted file systems? Have I misunderstood the disk utility fs check repair function? And anyway, what might be a good answer to my (nontechie) friend's question 'After so many reboots it checked disc for errors and repaired itself! Is there some way of doing that when needed anyway?'
For the record: (quote) It is a toshiba EA60-155 Model number PSA67E-00300C8J. He put in extra ram to install ubuntu. He thinks he may have deleted something! There is a 'trash' file on his USB drive with loads of stuff in it and he doesn't know how or why but because it won't now read the drive on her laptop we cant replace it! (end quote)
how can I disable the automatic file system check after power outages or system crashes? The check sometimes prompts for a key (ignore, repair etc.) but the panels do not have a keyboard.
