As others have said that looks like a loose-loose situation. (Starting at the end) Completely new deployment Of course you can't just take the servers down and let the installer do it's magic. General Process Get budget for a backup server (backup as in storage for the data) create snapshots of the data and place them there before doing anything Get ...

You can trace the execution of a series of scripts using bash -x bash -x /path/to/your/script From this you can figure out which scripts are being called. You can force the script to abort early using the -e switch bash -e -x /path/to/your/script which may save you having to wade through lots of output

Screens tend to be a very personal thing - I don't think there's one universal set of "must-haves". That said, I'd recommend steering clear of the "glossy" displays and pay the extra few bucks for those with antiglare screens. Additionally, make sure that the monitors are VESA mount compatible so that you can attach them to a dual monitor arm if desired. ...

I'm not a monitor expert, but I'll offer you the qualities I like in monitors I have to stare at all day: Height adjustment. It's important that you not look down at your monitors all day. I can say from personal experience this leads to neck strain. My monitors are currently sitting on an empty 2U rail kit box to bring them up to the right height. ...

Nagios is a monitoring and alerting system, which has graphing capability (if you pay for it). Cacti is a graphing system, which does not have alerting capabilities (at least not years ago when I used it last, and there's no mention of it on the Cacti site). The two are related (and often paired to avoid paying for the commercial Nagios implementation), ...

Most server-based hardware, or server motherboards now a days have some sort of on-board network based KVM systems that allows remote administration of a machine, most of the time it's called IPMI. It allows you, with the correct license, the ability to pull the console (screen) and send keyboard and mouse entries directly to the server, and also mount ...

First of all, if you're going to invest extra time in this I'd advise you to actually get paid for it. It seems you've accepted unpaid overtime as a fact, judging from your words - it shouldn't be that way, in my opinion, and specially not when you're in such a pinch because of someone else's fault (be it management, the old sysadmin or probably a ...

Do you have reason to believe that the previous admin left something bad behind, or do you just watch a lot of movies? I'm not asking to be facetious, I'm trying to get an idea what sort of threat you think is there and how probable it is. If you think the chances really are very high that some sort of seriously disruptive problem might really exist then ...

I've seen in Tekzilla a tool, named JDiskReport which runs on several OSes. Actually I haven't tried it out on any Linux yet but on Vista it is great. And it is a Java application therefore it should work on Linux too.

The Windows AIK is the officially supported way of doing this, and is available for the Windows 7 RC (discussion here: http://www.mydigitallife.info/2009/05/06/windows-automated-installation-kit-aik-for-windows-7-rc-official-download/ ) You should note though that it requires quite a bit more work that you may be happy with, but you can be certain that the ...

Look at Apt-Proxy. apt-proxy is a program that caches the packages you download from the Internet, to your hard disk. Because apt-proxy behaves as if it were a HTTP server with a full copy of the repositories you select, you can access the packages from other computers on your network. If a package is not in the cache, apt-proxy automatically downloads ...

Simple: Nagios was built with alerting first. Cacti was built with graphing first. Both have addons that will enable the functionality of the other, but it boils down to what you want. If you already have a monitoring solution, and just want performance graphs Cacti might make sense. If you want a single unified solution with an emphasis on monitoring, ...

You can use the setx command to set the PATH that will be given to newly opened shells. Combine that with an autorun batch file and you should be in good shape. You will have to reverse the procedure before ejecting the drive though. As an alternative, have a cmdln.bat on the drive that opens a shell with environment configured how you would like it. That ...

I used to use apt-cacher, but I've since replaced it with apt-cacher-ng. What you need to do is On the server, apt-get install apt-cacher-ng On the server and the clients echo 'Acquire::http { Proxy "http://server:3142"; };' > /etc/apt/apt.conf.d/99apt-cacher-ng, replacing server with the domain name or IP address of the machine running apt-cacher-ng ...

Virtualization is a great way to give everyone their own "sandbox". LXC definitely is an option but you could also just use VMWare ESXi or Citrix XenServer. Both have commercial variations but they also have single-server free licenses. The reason using ESXi or XenServer might work better is the ease of being able to take snapshots or cloning systems. So ...

You probably mean the remote server administration tools (RSAT) package. Those are updated infrequently - so far there has been an update for Windows 7 SP1 and this specific one only seems to affect the installer and not any of the accompanying tools. The older toolkit releases have not been updated too often too - the latest and final release of the Windows ...

The solution depends on the size of the datacenter and the hardware of the servers. I manage a small datacenter. We use KVM switches with one vga connection per server. They are stackable, 10 servers per switch, allowing a total of about 100 servers. There are also KVM switches that pass the signal over ethernet to the terminal. Many servers provide ...

Midnight Commander (mc) is the usual answer, but there are others. I'd recommend you take a look at GNU Interactive Tools, or GNUit (it was git before Linus "reappropriated" the name...) Like other GNU tools, it has EMACS-like bindings throughout. GNUit is console-based and extensible, and has the dual-pane file manager layout with a command line ...

I can only tell you what I do, since there are a billion ways to approach this. We use Puppet for systems management at my company so I populate my .bashrc with lots of functions and aliases. For example (your example reminded me of mine): alias sp='du -mx . --max-depth=1 | sort -nr | head' If I ever want to remind myself what I've done, I can look at ...

Sounds like you want to use a versioning tool like svn/Subversion or git rather than rsync. It perfectly fits your need plus the benefit of rolling back if an edit messes something up. Take a look at the Subersion Homepage and/or git HOWTO.

If there are not too many people in that group, just deactivate that group and see what happens. It helps to tell anybody in that group what you are doing, so you can quickly investigate when something doesn't work anymore. Don't do that on your last day before you go on vacation. ;) The assumption is that you don't user user accounts (from you staff) for ...

ShareEnum and AccessEnum would be the tools I'd use to try looking for Share/NTFS permissions related to the group. http://technet.microsoft.com/en-us/sysinternals/bb897442.aspx http://technet.microsoft.com/en-us/sysinternals/bb897332.aspx You should also consider that it's entirely possible that users were added to a security group only for the purpose ...

$ du -sh foldername 408K foldername $ man du du - estimate file space usage -s, --summarize display only a total for each argument -h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G) it's manual but it works wonders if you hook it into a script

You might be interested in agedu. From the description "It does basically the same sort of disk scan as du, but it also records the last-access times of everything it scans. Then it builds an index that lets it efficiently generate reports giving a summary of the results for each subdirectory, and then it produces those reports on demand. "

If you already have all the scripts for the custom tasks then you can easily integrate them to many of existing monitoring solutions, both software ans cloud-based. You will then get graphs, reports and all the standard stuff monitoring. For instance, you may try Anturis - the one i'm involved with. However, it is more for servers with web stack rather than ...

You mention not using Nagios in your problem description but this seems like the kind of thing one would normally use Nagios for, writing whatever custom tests you need as plugins to the Nagios agent and aggregating the results using the Nagios console, as as using the built-in plugins for pinging, etc. The time would be spent more on learning how to use ...

Try Krusader. The only disadvantage of it is graphical interface. So it will be difficult (but possible *) to use it remotely. * Do you know about X11 forwarding? It gives you ability to run at server GUI applications and work with their GUI locally. All interaction with user and windows is translated through network. Usually one uses ssh with -X switch ...

What you seem to be looking for is a local mirror of a package repository. Here is a small guide on how to do this with Apt-mirror. It's a few years old, but still relevant. After you set up the mirror, you can point all your other servers/desktops to the local mirroring host for updates (Explained at the bottom of the guide).
