Svish's questions

I can create a web site in IIS using e.g. the following command:

appcmd add site
  -name:portallocal
  -physicalPath:"C:\dev\projects\mysite"
  -bindings:https/127.0.0.1:444:mysite.dev

But how can I also select an SSL certificate?

I'd like the highlighted dropdown shown below to have the correct SSL certificate selected, and I'd like to do it from the command-line, preferably as part of the add site command. if there's an additional command I can run, that's fine too, but I want to not have to go into the IIS Manager application and select the SSL certificate manually.

We have the following monit config which restarts tomcat if unable to connect to it:

check host Tomcat-Foo with address localhost
 stop program = "/usr/bin/systemctl stop tomcat.service"
 start program = "/usr/bin/systemctl start tomcat.service" with timeout 360 seconds
 if failed host localhost
        port 8081
        protocol http
        request "/foo/"
        for 3 times within 5 cycles
 then alert

The problem is that it takes quite a while to start up, and monit seems to keep checking. This means that while tomcat is starting up, monit seems to think it is down "again" and initiate another restart, turning it into a restart loop.

Is there an easy way to have monit pause/disable the checking until tomcat is in fact back up again?

Alternatively if this config should look completely different so it wasn't an issue to begin with?

I have tried to set up a scheduled backup of my Minecraft server. I used a script I found on GitHub at frdmn/minebackup.sh and it seems to work great when I run it from the terminal directly.

The cronjobs I have set up however doesn't work for some reason. In mails I get these error messages:

Hexxit Server is running, suspending saves... su: must be run from a terminal
su: must be run from a terminal
su: must be run from a terminal
done
Backing up hexxit-01... done
Total backup size (175 MiB) <= (5000 MiB)... done
Hexxit Server is running, re-enabling saves... su: must be run from a terminal
su: must be run from a terminal
done

The main problem seems to be su: must be run from a terminal and I assume this has to do with security issues on the server and not the script, so that's why I'm asking here.

It's more or less a freshly installed instance of Debian 7.1.0 x64 with one user on it, mc. How do I fix it so that this script runs successfully?

The cronjobs look like this and have been added using crontab -e

*/15 * * * * /usr/bin/minebackup backup
0 0 * * * /usr/bin/minebackup backup full

I've been searching around for a bit and I have a feeling I need to edit /etc/sudoers, but the line which I was supposed to comment away isn't even in the file, so I don't know if Debian has changed its defaults or... eh?

Defaults        env_reset
Defaults        mail_badpass
Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

root    ALL=(ALL:ALL) ALL

%sudo   ALL=(ALL:ALL) ALL

#includedir /etc/sudoers.d

I can add to the PATH variable from the console using the following command:

setx PATH "%JAVA_HOME%\bin;%PATH%" /m

However, when I check the PATH variable afterwards the JAVA_HOME variable has been expanded so that the actual PATH looks like X:\Path\To\Java\bin;... instead of %JAVA_HOME%\bin;.... Is there a way to use setx like I do here without having the JAVA_HOME variable expanded?

Tried using double %% but that just gave me the expanded version with a percentage on each end. Also tried \%, but that just messed it up.

A website I've been helping out with is hosted on a web host (not my choice) that only provide FTP to files (no shell access) and the database can only be accessed from the host itself or phpMyAdmin.

The website is running on Apache with PHP version 5.3.13.

Since bad and unforeseen things happen to websites from time to time, I'd like to have a backup of the website. I of course have most of the infrastructure locally already (database schemas and website source files), but if the website got hacked or something else bad happened, I would be left with a blank website. So I of course need to back up all user uploaded media and all data in the database.

Problem is I'm really unsure how to do this in a good way when all I have is FTP access and no direct access to the database. Any advice on how to get a decent automatic backup of this site that can be run periodically without too much trouble?

We are testing out Hyperic 4.5.1 in a quite small environment for now. Currently there are just 1-5 agents and there probably won't be any more than 10-15.

When I run ps ax there are 20(!) postgres processes running. For a small setup like this, that can't be necessary, can it? I'm a software developer and don't have much experience with setting up servers and such though, so don't really know.

Either way, what settings are appropriate for a small Hyperic setup like this?

Current, default and untouched configuration file, hqdb/data/postgresql.conf:

# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# (The '=' is optional.)  White space may be used.  Comments are introduced
# with '#' anywhere on a line.  The complete list of option names and
# allowed values can be found in the PostgreSQL documentation.  The
# commented-out settings shown in this file represent the default values.
#
# Please note that re-commenting a setting is NOT sufficient to revert it
# to the default value, unless you restart the server.
#
# Any option can also be given as a command line switch to the server,
# e.g., 'postgres -c log_connections=on'.  Some options can be changed at
# run-time with the 'SET' SQL command.
#
# This file is read on server startup and when the server receives a
# SIGHUP.  If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload". Some
# settings, which are marked below, require a server shutdown and restart
# to take effect.

Not sure what I did, but for some reason the network adapter no longer shows up in my guest os running Ubuntu. When I run ifconfig, only the lo interface is listed. The Network Adapter settings for the guest is this:

What's going on?

ifconfig -a

dmesg | grep -i eth

I was wondering if someone could give me a simple guide on how to set up virtual networking in VirtualBox (4.0.2) so that the following scenarios work:

• Both Host and Guest can access the Internet
• Host can ping Guest and vice versa
• Host can access, for example, an apache web server running on Guest and vice versa

I've been fiddling around with the various Network Adapters available in the settings for my Guest, but I'm just not able to figure it out. Is there anyone that can help me out here?

The host is running Windows 7 32-bit and the guest is running Ubuntu 10.10 32-bit.

Is there a way I can do the following in a unix terminal:

1. Start a long running process
2. Add another long running process to start when the previous is done
3. Repeat step 2 until I have queued the processes I need to have run

Reason I ask is that I have some long running stuff I need to do. I could put all the commands in a simple bash script and just execute that, but the problem is that I am not always sure exactly what I need to run. So if I start the script and then remember another one I should run, I need to hit ^C a bunch of times until all the processes are killed, edit the script and add my new process and then start the whole thing again.

What I specifically am doing right now is to copy a lot of large files on to various external hard drives, and since I don't know exactly which ones I need to copy and to where right now I'd like to start the ones I do know I need to copy, and then add to the queue as I figure out the rest.

Hope that made sense... Is anything like this possible?

This is really annoying... I need to administer a Mini Server running Mac OS X Server 10.6. Should be easy by using the Server Admin Tools I thought, but no. To administer a server running Mac OS X Server 10.6, I need Server Admin Tools version 10.6. Fair enough. But, to run Server Admin Tools version 10.6 I need Mac OS X version 10.6?! Coming from a Windows world, that makes no sense to me what so ever. Isn't Server Admin Tools just an app? What makes it even more annoying is that to get Mac OS X 10.6, I need Intel, and we have no macs running Intel here yet.

Soo... what can I do here? How can I administer that server? What are my options? Do I have any options at all? Or do I seriously need to buy another mac just to administer that mac server?

Note: I know I can put a screen on it, but it's location is so that that would not really be a workable solution.

What does the Job Options of RoboCopy do? And what exactly does the /MON and /MOT switches do? How can I use them? I don't understand them, and can't find any examples on how to use them.

• /MON:n - MONitor source; run again when more than n changes seen.
• /MOT:m - MOnitor source; run again in m minutes Time, if changed.

Does this mean that it will run one time first and then keep running after it finishes and run again if a change happens somewhere down in the filestructure or when something have changed and a time has passed?

• /JOB:jobname - take parameters from the named JOB file.
• /SAVE:jobname - SAVE parameters to the named job file
• /QUIT - QUIT after processing command line (to view parameters).
• /NOSD - NO Source Directory is specified.
• /NODD - NO Destination Directory is specified.
• /IF - Include the following Files.

What is a job file? What is the /NOSD and /NODD switches for?

I thought I would try out RoboCopy for mirroring the contents of a folder to another harddrive. And seems like it worked. But, for some reason, to see the destination folder I have to both enable Show hidden files, folders and drives and disable Hide protected operating system files. Why is this? Both the source and destination folder was initially both visible and normal directories. When I open up the properties for that destination folder, the Hidden attribute is even disabled. What is going on here?

Is it because I ran it in an administrator command prompt? Or is it an issue with my choice of modifiers? Or does robocopy really just work this way?

robocopy E: I:\E /COPYALL /E /R:0 /MIR /B /ETA

Update: Tried to copy another drive to another folder, and I got the same thing happening there. But when I try to just copy a folder to a different folder, then the destination folder stays normal. Could it be because I copy a drive? If so, how can I prevent this from happening? Cause I really do want to copy the whole drive...

I finally figured out how to get internet access on a Windows 7 guest running on Virtual PC 2007, as described here. But one I don't get. I am not able to ping or tracert anything. Google.com for example. On the host I can both ping and tracert it. On the guest I can do it to neither of them. All I get is Request timed out. But I can visit google.com in IE.

What is going on?

Is Virtual PC on Windows 7 x64 only able to virtualize x86 versions of Windows 7?

Can you help me with my software licensing question?

I have Windows 7 Ultimate running on my computer, and I thought I would set up a few virtual machines to help me when I develop so I don't mess up my main system with various installations of SQL Server, Visual Studio versions, etc.

Is it allowed (or even possible) to use the same product key for the virtual machines? Or would I need to get a new product key for each virtual machine?

Is Windows 7 Enterprise different when it comes to this matter?

(Maybe this belongs on stack overflow or super user, but felt virtualization and licensing issues like that belonged more on server fault. Please move if not =)

Raid-1 is mirroring two disks (if I haven't messed up completely here :p). Does that mean that I could take one disk out and put it into another machine and it would work like a normal disk? Or does it still only work in the raid? I can understand that a Raid-0 of course only works as a whole. But with mirroring I am not so sure how it works...

Of course putting the mirrored disk back in the raid afterwards would be a bad idea, but just taking it out... how would that work? Does raid store any special data on a drive that is needed? or does the raid controller handle everything like that and the harddrives are just used like normal?

Does software raid break when reinstalling the OS? If yes, is there any way to prevent it, or recreate it without data loss after the reinstall? If no, is there anything you have to remember when doing it so it doesn't? Or is it just fixed automagically?

The particular OS I am wondering about is Windows 7 and Vista, but more general answers are more than welcome.

Just ran Disk Cleanup on a computer here (Windows Vista), and saw 3 items in the list I haven't seen before:

• Per user archived Windows Error Repo... | 402 MB
• System archived WIndows Error Repor... | 18,0 KB
• System queued Windows Error Reporti... | 533 MB

What are those? I assume it is safe to delete, but should I do something with it first? Should I for example be kind to Mircosoft and send all that queued stuff? How would I do that?

Note: Wish I knew what was after those dots. Assume it is "Reporting", but no idea if there is more after it. Hate dialogs that can not be resized... (or at least lets me know what is behind truncated text in a tooltip)

Is it possible to install windows updates from the command-line? The graphical update tool doesn't seem to work so well in Windows 7. Sometimes it does, sometimes it doesn't... My problem is that I can't see any updates when I click to see the details list. So when there are updates that are not checked off by default, I can't install them...

So, is there an other way I can get those installed?

I was thinking of running maybe Windows Server 2008 or Windows Home Server on my home computer. But before I did the formatting etc, I would like to know if this is even possible. And I am then thinking driver wise. I have for example an ASUS motherboard with built-in network, wlan and audio, and an NVIDIA graphics card. But on the ASUS website there is not listed any drivers for these OSs. Only XP and Vista, etc.

Do you need special hardware to run these server OSs? Or can you use the Vista or XP drivers?
