Applications :: Get Last Logged In Date / Time For Vsftpd Users?

Aug 27, 2010

I can't seem to get last logged in dat/time for vsftpd users. They are linux users maintained within passwd groups ect ... i think this is because ftp doesn't actually give them a real session. That being true, how do i get the last logged in time for my ftp users?

Programming :: Get Real Time Information About How Many User Are Logged In And Their Ips

Jan 20, 2009

I use tomcat as my server platform in Ubuntu for a war file. I know in order to get real time information about how many user are logged in, we can count how many active sessions exist by a SessionCounter code. However, I have to permit HttpSessionListener in web.xml of tomcat. From other users' experiences, the configuration is complexed and has some errors.

Here's the link:


In order to get users'ip, in jsp, use request.getremotehost() or request.getremoteaddress() by editing the jsp file. I wonder if there's some open source software to use for these two purposes.

Ubuntu Servers :: Every Time Logged In Via SSH Got A Message Telling There Where Packages To Update Including A Security Update?

Feb 11, 2011

I was running 10.04 LTS and had decided to stick to the LTS versions as I'm now running my machine as a server and don't want to be updating regularly.Every time I logged in via SSH I got a message telling me there where packages to update including a security update. So I did a search to find out how to perform an update on Ubuntu server from the command line.What I found was to do this:sudo apt-get updatesudo apt-get dist-upgradeAfter doing that I rebooted but now my machine gives me this message:

init: ureadahead-other main process (794) terminated with status 4Your disk drives are being checked for errors, this may take some timePress C to cancel all checks currently inprogressI'm not pressing C yet and leaving it alone to finish, but I noticed when the machine booted that one of the options for booting talked about Ubuntu 10.10, so I'm worried that I've updated from 10.04 LTS to 10.10 by accident?

Networking :: Print AND Real-time Output Of PING Command ?

May 3, 2011

Let's say I am pinging a host, and want to output to a file each reply and its timestamp of when this started.

I know that it can be done with a loop and a shell script. Something like this


echo "$(date)" >> results.txt ###includes the time and outputs results to txt###
ping -c 4 HOST >> results.txt ###a total of 4 pings at a rate of 1 per second###


Now, my first issue is that I need to be able to see results real-time as well.

Is there a way one can print to BOTH a screen and output? If one uses the ">>" command, it is essentially sending everything to the file. Running another ping command in parallel is not an option.

Red Hat / Fedora :: Able To Vnc Into The Computer Without Having Logged Into The System Physically

Nov 6, 2010

I've used linux systems before, but the last time I actually set up a server was when fedora core 4 came out, which was, to say the least, quite a while ago. here's my core dilemma: atm, I have fedora 13 set up, and i'm looking to be able to vnc into it WITHOUT already having logged on as a user. I've tried various things and I'm having little to no luck. I uninstalled tigervnc and installed the original vnc package (With server) from I've also installed xinetd and tried to get it to incorporate vncserver as a startup service, to no avail.

I have not been able to connect to the vncserver regardless of how I try. I AM able to connect to the base remote desktop functionality provided by fedora (Also vnc based). However, as soon as I disable that, I am not able to vnc into it at all. Long story short, here are the current goals:

1) be able to vnc into the computer without having logged into the system physically
2) have those logins be un / passworded. i.e., be able to login as whatever user
3) complete disable the normal graphical startup that fedora provides, since I don't think there's ever going to be a person physically at the computer and I'd like to maximize system resources

Also, if VNC is NOT the easiest way to do something like this, please let me know, I'm completely amenable to taking another route. In short, I'd like non-physical per-user graphical access to the server. I'd also like it to be more than one single vnc session, as I may have it open from either multiple locations or multiple users.

Ubuntu :: System Freezes After Log Off With Multiple Users Logged In

On Ubuntu 10.04 when there are more than just one user logged in, if one of users logs off system hangs with a black screen.

After I reboot the machine and log in again, just after GDM login screen I get a window with a message about PowerMeter crash, with suggestion to 'cancel' and 'log off'. Only 'Log off' works, i.e. I'm successfully logged in.

Last entries from system.log before system freeze are:

Ubuntu Servers :: System Time Runs Slow Hareware Time Run Right?

Apr 11, 2011

I am running my Ubuntu 32 bit server on top of Windows 7 64 bit with VirualBox. It's a 2 core Atom. It's been working good for about half a year. But the last about 6 weeks the system time only in Ubuntu is going slow. About -8 per 24 hours! I can only guess because I have more things running in my Windows 7 and Ubuntu.

I can set it right by coping the hareware time to system time with this command:

hwclock --hctosys

I want to run a crontab to have that command run every minute. But it don't seem to run.

Server :: Logged Users Without Processes?

Nov 1, 2010

I try to write a script which would kill processes of users who are not logged in. My approach is to find out what users are logged in and then kill processes of all nonsystem users who fail the test of being logged. I use `w` for finding all logged in users, but apparently there are users on the list which `w` gives me who own absolutely no process in the output of `ps aux`. How do I log off those users, since killing their processes wont work (since they own no processes)?

CentOS 5 :: VNC Server - Works When Logged In Only

Sep 6, 2010

Been using CentOS for a couple of weeks and have a few quirks I need help with.
This is a fresh install of CentOS 5.5. I'd love for VNC Server to start up as soon as the computer reboots. It seems my VNC Server only works when I log in using the GUI at the computer itself. After a reboot I can remotely SSH into it successfully, but cannot VNC to it. I then have to physically get to the computer and log into the GUI, and wa-la I can VNC to it. I have not edited any conf files - seeing as my last attempt at getting this working got me nowhere. I have only enabled Remote Desktop through the GUI.

General :: Connect To Remote X-Server (logged In Via Ssh)

Jul 31, 2010

When I'm logged on to another host (e.g via ssh), how do I connect to the XServer of that machine (same user is logged in and is running a desktop (gnome))?

You may ask way I wish to do that: There are commands that don't open an X-Window, e.g. xinput, xhost, etc.. and there are situations where you want to run them from remote.

Ubuntu Servers :: FTP Not Responsive Unless Server Logged In?

Feb 1, 2011

I'm a total Linux noob, but I've needed a working development server for a while so I've put together an old celeron box running Ubuntu Server 10.10.The box runs fine, as does the Apache and MySQL servers, even if they did take a little while to fine tune!The problem I have is that vsftpd doesn't respond unless I'm logged on locally or via putty. As long as a local user is logged in, it's fine. If I try to connect when noone is logged in, then the connection times out waiting for the server message, and thereafter I have to login and stop / restart the vsftpd to make it work again.I'm not sure if the vsftpd is set to run on boot or on login and I have no idea how to check. Vsftpd is set to allow only local users, of which there is only one - so I can't check if it would work with any user logged in
