How to install Terminal Services On Small Business Server (SBS) 2003

I've found this document that explains how to install Terminal Services in application mode on a Windows Small Business Server (SBS) 2003: http://www.bagsolutions.orconhosting.net.nz/

Before you start you have to had finished the small business server setup!!!!

This will show you how to do what M$ said you could in the pre release versions of SBS 2003 but can't in the final release. This does not crack nor get you to edit any of Microsoft's code. It just does what the install would have done. We have tested this as much as we could we cannot guarantee that it will work or be held liable for any errors, unforeseen or otherwise, that might occur.

Does Open-E support Jumbo Frames?

Here you can find how to enable jumbo frames on Open-e appliances: http://kb.open-e.com/Does-Open-E-support-Jumbo-Frames_28.html
Open-E supports the use of Jumbo Frames.

Use Jumbo Frames to improve performance by sending fewer frames across the network, saving CPU time and consuming less bandwidth.  The standard recommendation for the size is 9000. 

The stipulation to using Jumbo Frames is that your network hardware, which includes Ethernet cards, switches, and routers, all need to support Jumbo Frames.  Check the specs on your Ethernet card to make sure Jumbo Frames are supported.  An example of one that does support them would be the Intel Pro/1000 CT.  So then you need to check the manuals on your switches and routers to make sure they also support Jumbo Frames, or check their websites with your model.  You'll need to know what you need to do to set your switches and routers to use Jumbo Frames.  Once your hardware has been verified, then it's just a matter of setting Jumbo Frames in the Console Tools of your Open-E server.

Go to the Hardware Tools
Ctl - Alt - W

Select Tuning Options
Select Jumbo Frames Config

Select the interface you want to set and set the number to 9000.

Connecting to a W2008 shared folder from W2000 or XP clients

Recently I've tried to connect to a W2008 shared folder from a W2000 server without success, however I've found this information at http://www.petri.co.il/how-to-disable-smb-2-on-windows-vista-or-server-2008.htm and now it's working fine. This applies to windows XP clients too.

How to Disable SMB 2.0 on Windows Vista/2008

Server Message Blocks Protocol (SMB) is the file sharing protocol used by default on Windows-based computers. SMB 1.0 was designed for early Windows network operating systems such as Microsoft LAN Manager and Windows for Workgroups, but until Windows Server 2008 and Vista, all Microsoft-based operating systems continued to use it more or less in its original format.
SMB 2.0 was introduced in Windows Vista and Windows Server 2008. SMB 2.0 is designed for the needs of the next generation of file servers. Windows Server 2008 and Windows Vista support both SMB 1.0 and SMB 2.0 in order to preserve backward compatibility.
Some of the enhancements in SMB 2.0, include:

• Sending multiple SMB commands in the same packet which reduces the number of packets sent between a client and server
• Larger buffer sizes
• Increased scalability, including an increase in the number of concurrent open file handles on the server and the number of shares that a server can share out
• Support for Durable Handles that can withstand short network problems
• Support of Symbolic Links

Testing done with copying large files between Windows Vista and Windows Server 2008, and then Vista to Windows 2003, have shown that by using SMB 2.0 the file copying was, in average, 2 times faster than with older operating systems.
However, while SMB 2.0 seems to do a good job if BOTH client and server OSs support it, in some cases it will slow things down. The reason for this is that the version of SMB used for file sharing is determined during the SMB session negotiation. If both the client and server support SMB 2.0, then SMB 2.0 is selected during the initial negotiation. However, if they don't both support it, SMB 1.0 will be used to in order to preserve backwards compatibility.
The SMB protocol version to be used for file operations is decided during the negotiation phase. During the negotiation phase, a Windows Vista client advertises to the server that it can understand the new SMB 2.0 protocol. If the server (Windows Server 2008 or otherwise) understands SMB 2.0, then SMB 2.0 is chosen for subsequent communication. Otherwise the client and server use SMB 1.0.
When using the terms "client" and "server" in case of file and print sharing, it does not necessarily mean that a client-type OS such as Vista "always" connects to a server-type Os such as Windows Server 2008. Sometimes, a Vista computer will connect to another Vista computer, and in that case, the computer that is "serving" the shares is considered to be the "server".
Here's how SMB is used when related to SMB versions:

• When a Windows Server 2008/Vista "client" connects to a Windows Server 2008/Vista "server", SMB 2.0 is used.
• When a Windows Server 2008/Vista "client" connects to a Windows 2000/XP/2003 "server", SMB 1.0 is used.
• When a Windows 2000/XP/2003 "client" connects to a Windows Server 2008/Vista "server", SMB 1.0 is used.
• When a Windows 2000/XP/2003 "client" connects to a Windows 2000/XP/2003 "server", SMB 1.0 is used.

So, for troubleshooting purposes, mostly in an environment that has mixes operating systems, you might want to consider disabling SMB 2.0. So you need to do on both the "client" and the "server" operating systems. To disable SMB 2.0 for Windows Vista or Windows Server 2008 systems that are the "client" systems run the following commands:

sc config lanmanworkstation depend= bowser/mrxsmb10/nsi

sc config mrxsmb20 start= disabled

Note there's an extra " " (space) after the "=" sign.
To enable back SMB 2.0 for Windows Vista or Windows Server 2008 systems that are the "client" systems run the following commands:

sc config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi

sc config mrxsmb20 start= auto

Again, note there's an extra " " (space) after the "=" sign.
In order to disable SMB 2.0 on the server-side computer, follow these steps:

5. Reboot the server.

Fix Missing eth0 When Cloning Ubuntu VMware Virtual Machines

I've found this site: http://www.orzeszek.org/blog/2010/07/25/fix-missing-eth0-when-cloning-ubuntu-vmware-virtual-machines/ that explains how to resolve this issue:

Fix Missing eth0 When Cloning Ubuntu VMware Virtual Machines
by Chris on 25 July 2010

I ran into an annoyance trying to clone some Ubuntu LAMP virtual machines that I was using for website development. Every time I cloned the virtual machine, eth0 would go missing, and ifconfig would show only the loopback device, lo.

It turns out that when you clone a VMware virtual machine, the cloned virtual machine’s network interface gets a new MAC address (which, of course, it must to work on the same LAN). But Ubuntu, and many other Linux distributions, cache the old MAC address in a configuration file.

In Ubuntu, the file is /etc/udev/rules.d/70-persistent-net.rules. After cloning, it will contain a reference to the old network interface as eth0.

The easiest way to fix this problem is to simply delete the file. Ubuntu will regenerate it properly the next time it boots up.

sudo rm /etc/udev/rules.d/70-persistent-net.rules

After deleting the file, you need to reboot. After rebooting, ifconfig should show eth0 and everything should just work.

If you’re feeling less adventurous, you can rename the file to *.old so that you can restore it if something doesn’t work:

sudo mv /etc/udev/rule.d/70-persistent-net.rules /etc/udev/rule.d/70-persistent-net.rules.old

You can also edit the file to remove the old reference to eth0, and rename the new eth1 reference to eth0. But deleting the file and rebooting seems more convenient.

The relevant filename is slightly different in other Linux distributions. For example, in Debian, the filename is /etc/udev/rules.d/z25_persistent-net.rules.

P.D.: (03-08-2011) - In Suse 9 you must delete the file /etc/sysconfig/network/ifcfg-eth-id-xx:xx:xx:xx:xx:xx where xx:xx:xx:xx:xx:xx is the old MAC address.

How can my bash script output Unicode?

Finally I found how to print Unicode characters from a bash script: http://forums.debian.net/viewtopic.php?f=10&t=45394

Here is the code from 'hedgie' that works for me:

VMware ESX 3 – use lwp-download to grab files

If you need to download an iso file from a ESX 3.x console, you can use the command lwp-download.

First http port must be opened at firewall level:
esxcfg-firewall -o 80,tcp,out,http

Then you can get a file with the command:
lwp-download <url> [<localfilename>]

And finally you should close http port at firewall level:
esxcfg-firewall -c 80,tcp,out,http

VMware ESX 4 – use cURL to grab files

I've found this information by Eric Gray at http://www.vcritical.com/2009/05/vmware-esx-4-use-curl-to-grab-files/

I need to quickly download an ISO image to my new VMware ESX 4 box and discovered that the cURL utility is now included — pretty handy.

If you have not used cURL, it is similar to wget. However, with no parameters cURL will spew the download to standard out — definitely not what you want in the case of an ISO image. Therefore, the -O option — capital O — can be used to save the downloaded file, preserving the filename. If you happen to be behind a proxy server, don’t forget to set the http_proxy environment variable — standard Linux procedure.

[root@cl-168 Storage1]# export http_proxy=http://proxy:3128

[root@cl-168 Storage1]# curl -O http://mirros.easynews.com/linux/ubuntu-releases/hardy/ubuntu-8.04.2-server-amd64.iso

Also you can connect using ftp protocol as follows:

curl -O ftp://myftpsite.com/filename --user myname:mypassword

Random times in a batch file

You can use random times in a batch file using something like that:

echo randomize >C:\TMP\random.vbs
echo wscript.sleep Int(Rnd * 100000) >>C:\TMP\random.vbs
cscript C:\TMP\random.vbs
dir

Here is a more elaborated example (only for the vbs script):

TopWait=8       'Max. time to wait in hours
randomize
myrand = rnd()
Wait=Int(myrand * 3600 * TopWait)  'Time to wait in seconds

Hours=Wait \ 3600
Minutes=(Wait - (Hours*3600)) \ 60
Seconds=Wait - (Hours*3600) - (Minutes*60)

WScript.Echo "Waiting: " & Wait & " seconds => " & Hours & ":" & Minutes & ":" & Seconds
wscript.sleep Wait * 1000    'Must be in miliseconds
WScript.Echo "Done: " & Wait & " seconds sleeping"

REFERENCES

WScript.Sleep
Suspend the execution of the current script for the specified number of milliseconds.

Syntax
WScript.Sleep lngTime

Arguments:
lngTime is the delay in milliseconds

Example
WScript.Sleep(5000)
WScript.Echo("5 seconds have passed.")

Rnd
Return a random number

Syntax
Rnd[(seed)]

Key
seed A seed value of 0 will return the most recent random number
A seed value > 0 will return the next random number(default)
A seed value < 0 will return the same number

Example
myrand = rnd()
WScript.Echo myrand

Unattended access to Netscreen devices from vb script

I've found this post at experts-exchange: http://www.experts-exchange.com/Software/Internet_Email/File_Sharing/SSH_Telnet/Q_22920318.html

Here is a VBScript that should do what you are looking for. Just remember your credentials are in plain text in the script, set your permissions accordiningly:

set WshShell = WScript.CreateObject("WScript.Shell")

WshShell.Run "C:\putty HOSTNAME -l LOGIN -pw PASSWORD"      ' put putty in C:\
WScript.Sleep 2000
WshShell.AppActivate "HOSTNAME - PuTTY"      'insert correct hostname
WshShell.SendKeys "command"             'insert dns refresh command
WScript.Sleep 100
WshShell.SendKeys "{ENTER}"
WScript.Sleep 1000
WshShell.SendKeys "exit"
WScript.Sleep 100
WshShell.SendKeys "{ENTER}"
You will need to put putty in you C:\ directory or give it an absolute path

Good Luck

Windows 2003 synchronize with a NTP Server

This info is based on  http://etherealmind.com/ios-configure-windows-2003-xp-use-ntp-server-sync-time-clock-router/

Stop the Windows Time Service using the CLI.
net stop w32time

You must configure your NTP Servers:
w32tm /config /manualpeerlist:"hora.rediris.es,europe.pool.ntp.org",0x8 /syncfromflags:MANUAL
The peer list must be enclosed
Use the 0×8 flag to force W32time to send normal client requests instead of symmetric active mode packets.

Restart the Windows Time Service and then force a sync.
net start w32time
w32tm /resync

Save Netscreen config file from CLI

I've found this deimark's post in experts-exchange that explains how to save the Netscreen's firewall configuration from CLI.

From the webui you can save a copy of the config hen you view it. I would suggest using tftp to do this.

ie set up a tftp server and enter the following commands:
get config > tftp <ip address of tftp server> config-file.txt

Similar to what you would do for backing up and upgrading the screenos image.

Namely to back up:
save config from flash to tftp <ip address of tftp server> <filename>

To upgrade your system:
save config from tftp to flash <ip address of tftp server> <filename> to flash
reset
