One domain, port 80 on one server, port 443 on a second server.

First of all, this will be a temporary setup. I need http on server1 and https on server2. The AnaolgX PortMapper did the trick. I installed it on server1 and mapped 443 to server2. The new server is a Citrix gateway and the other solutions I tried resulted in SSL errors. The proxy works so far with no issues.

http://server1 -> old server
https://server1 -> new server

Server1 will be the proxy so it should have plenty of resources to handle the load.

Your browser is too old to view our site. User agent problem?

Lately I have noticed more web sites that will block you if your browser is too old. Why not just give a warning and recommend a new browser. I had one PC with this problem and Internet Explorer 8. So I went to a few test pages like whatismybrowser.com and they show I am using IE6 compatibility mode. Compatibility mode is NOT on. If you have this problem, go to the registry and delete Pre and Post tokens. All the blocked sites work now.

HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)
   SOFTWARE
      Microsoft
         Windows
            CurrentVersion
               Internet Settings
                  User Agent
                     Pre Platform
                        Token = Value
                     Post Platform
                        Token = Value

Stuck screensaver on OSX.

I lock the screen and step away. When I return the screensaver will not stop. This has happened a couple of times on the Mac Mini running Lion. Sometimes it is just slow to respond but this time I waited about ten minutes.

I did an SSH from another computer and killed the screensaver process. This worked but is very annoying. You must have the SSH enabled ahead of time.

ps ax | grep -i screensaver 
83230   ??  U      3:09.28 /System/Library/Frameworks/ScreenSaver.framework/Versions/A/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine 
sudo kill  83230

How to erase the config on a Foundry EdgeIron switch.

I searched for the a quick way to default the configuration on an old Foundry switch. Password recovery is not the issue since I have the password. This is the only fix I could find.

copy file startup-config
filename: Factory_Default_Config.cfg
reload 

Let me know if you have a better way to do this.

Cisco PRI connecting to NEC PBX.


This is want I need to setup.

Telco provider < Sip trunk > Cisco 5350 < PRI > Nec phone switch.

Here is my config for the PRI link. "protocol-emulate-network" is required when there is no service provider clocking the PRI.

controller T1 1/0
 framing esf
 linecode b8zs
 pri-group timeslots 1-24

!
interface Serial1/0:23
 no ip address
 encapsulation hdlc
 isdn switch-type primary-ni
 isdn protocol-emulate network
 isdn incoming-voice modem
 no cdp enable

These commands were also helpful.

show controller T1 ( Look for the T1 to be up with no errors.)
show isdn status ( Look for the lines below, especially MULTIPLE_FRAME_ESTABLISHED.)
debug isdn q921

#sh isdn status
ISDN Serial1/0:23 interface
******* Network side configuration ******* 
dsl 0, interface ISDN Switchtype = primary-ni
    Layer 1 Status:
ACTIVE
    Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
    Layer 3 Status:
0 Active Layer 3 Call(s)

Mitel command line trunk busy-out.

I have a Mitel with two PRI circuits. The 2nd PRI is bouncing every few minutes. Almost every time you get on the phone, the call is dropped. I wanted to busy-out or disable the 2nd trunk group to force all the phone calls to the good PRI. I could not find a way in the GUI so back to the command line.

busy trunk group 2 ( The status of the lines will change to man-busy.)
rts trunk group 2     ( Return to Service.)

The first time I tried this, the status of the lines changed to "not seizable." The command below fixed that.

dtstat clear 3 1 3 1   ( This command restored the lines to Idle. You will need to find cabinet, shelf, slot, and circuit to use dtstat.)

Now I wish the telco provider would get the PRI fixed!

Mitel 3300 command line intro.

You may have used the "Maintenance Commands" tool form the Mitel web interface. You can also telnet to the system and use some of the same commands. This is good for me because it works on a Mac which I use most of the time. I have always been irritated that the GUI requires IE.

telnet 10.1.2.3
system / xxxxxx  (Hint: This is not the same system password as the GUI)

There is a numbered menu bar at the bottom of the screen. To use these functions, type Esc and the number.

Here are my favorite commands.

stat trunk group 1 (This shows how many lines are busy)
cong (Traffic congestion report)
traffic status (I have not figured out how to use this feature yet but I want it)
loc num xxx (Identify extension number)
loc feat ext xxx (Shows if an extension is forwarded or if message light is on)

I will explore this CLI more later on.
