Software :: Understanding Output From "last"?
Jan 19, 2010I hope this is the correct forum for this question. When I use the "last" command, it gives me the list of successful logins. Can someone tell me what "pts/3" (or 1, 2, 4, etc) means? Example:
Code:
fivet sshd wireless68-198.w Wed Jan 13 10:48 - 10:48 (00:00)
fivet pts/3 wireless66-108.w Tue Jan 12 16:59 - 17:00 (00:00)

View 2 Replies View RelatedServer :: Use System Monitor Via A VNC Connection The Free Disk Space Value Is 20GB Free On The Same Volume
May 18, 2011I've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: - from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert.

Ubuntu Servers :: Not Quite Understanding UUIDs And Grub2 On 10.04 Server?
Jul 16, 2010I'm trying to set up an Ubuntu server using 10.04 (64-bit), and running into problems after a couple of reconfigurations. Here's the full story:I initially built the server on a 400+GB RAID5 array, putting everything but swap in one partition. Unfortunately, I needed to repartition, putting / in the first primary partition, swap in the second partition, /var/log in the third primary partition and /home in the remaining space on the fourth primary partition.
However, at this step, I ran into some problems with UUIDs in /etc/fstab and Grub2 (I've used Linux for about 9 years, but I'm new to Ubuntu, and I haven't used UUIDs or Grub2 on Gentoo, yet). Consequently, I made the (probably not smart) decision to move back to the /dev/sdX notation I am familiar with.The problem with that is that now I need even more space on /home, so I've added a Dell Powervault and a Dell PERC5/e SATA card to my server. Now, Grub2 tries to boot from the new RAID array on the Powervault instead of the internal RAID array, so I am trying to move back to the UUID notation so that I don't have worry about /dev/sda being the internal array sometimes and the external array at other times.I don't mind being RTFM'd, but I'm having trouble finding pointers to the documentation explaining Grub2 configuration and the UUID notation. Does anyone have pointers to some readable, concise documentation on configuring this in Ubuntu?
Server :: Understanding Server URL Structures?
Oct 27, 2010I guess I am trying to understand how webmaster's configure their servers on the Internet. I see servers that have the following:[URL]hat the webmaster above for 'mydomain.tld' has three separate unique servers for each hostname (mail, wiki, and www) above. Is it possible to get all the hostnames or aliases above running from one single piece of hardware? If so, how does that work? Obviously my single server will only have one unique hostname.

Ubuntu Networking :: Best Free FTP Server With GUI?
Jun 2, 2010I'm looking to set up a simple FTP server with an Ubuntu 10.04 box that I'm using as a file server. So far, I've tried a couple FTP server apps from the repos. One was proftpd with gadmin installed for the GUI. The other was pure ftp, with PureAdmin installed as the GUI. The problem I'm having is that gadmin seems buggy, and PureAdmin I cannot seem to make work properly. Another dilemma of mine is that I have two large hard drives with several folders on them. I only want to share a couple folders from each drive, but have them how up in the home directory of the user that logs in.
It seems like I may need a strong program that supports virtual folders (like Wing FTP), but I wanted to see if anyone out there in the Ubuntu world uses a free one that can help me make folders from different hard drives appear as though they're organized in one home directory?
Server :: /usr Missing Free Space?
Aug 23, 2010just some time ago, my /usr partition's used space is started to increase rapidly, and currently it reached 17.5GB. We put /usr as a separate partition (/dev/sda2)
So when we do "df" this is the result:
Code:
#df
...
/dev/sda2 20315844 17612628 1654576 92% /usr
...
But what makes me puzzled is if I do "du", I only get 4.3GB instead of 20GB as "df" reported.
Code:
# du -csh /usr
4.3G /usr
4.3G total
So I'm missing approx 13GB here. My question is:where does my 13GB missing?

Ubuntu Installation :: FREE Support For FREE OS?
Jun 10, 2010Am I asking too much for a FREE OS? Everybody spend their precious time to help others, that's very helpful.But it seems like there is no support from UBUNTU team,how could we even get through the barrier of not using Microsoft's OSes? No free lunch of course, but it seems to me some issues have never really been solved.I read lot's of people have problem with their WIFI, not just for my OLD USB wifi adapter. I don't have problem with WIFI in XP/Server.
I posted here and there, and seems like no answer, and I do not get any reply from UBUNTU support team,forgive me if I run out of google's keywords.I just need a simple answer, is my WIFI going to work in UBUNTU with a layman effort? I like linux and UBUNTU had put great effort in providing me such a great OS, but if a basic internet connection will need to spent sooo much time to setup, and it still doesn't work. IS IT WORTH to switch to UBUNTU at all
General :: DD Imaging Of Builds Better Understanding
Nov 12, 2010I am learning how to use DD for creating images across networks and locally but needed some clarification.
1 - When creating an image, I noticed that there is no verbose to show you the progress, How can I accomplish this?
2 - When I run this on a 8G usbstick it takes a long time to image. How can I speed up this process?
PHP Code:
dd if=/dev/sdb of=/home/test/images/image.dd
3 - When an image is restored like
PHP Code:
dd if=/home/test/images/image.dd of=/dev/sdb
will that give me a working bootable usbstick? For example if I imaged a working usbstick with Ubuntu on it using DD and restored it like the example above on a different usbstick, will this give me a booting new usbstick? I hope that came across ok?

As you can see, /home claims to be 100% full - but yet there is actually 18Gb free? I seem to recall this could be something to do with running out of inode space?
