==== URL Telnet/SSH/VNC Integration On Windows
http://www.unetlab.com/2015/03/url-telnet-ssh-vnc-integration-on-windows/
UNetLab is currently using two console types:
textual: using the telnet:// URL
graphic (included non-serial textual consoles): using the vnc:// URL
On Windows the VNC viewer suggested is UltraVnc.
* PuTTY
* UltraVnc
* additional file from UNetLab repository
Install UltraVnc using default settings. By default destination path is C:\Program Files\uvnc bvba . Unpack the Windows 64bit Url Integration.zip file, move the vnc_wrapper.bat file in the same folder of UltraVnc C:\Program Files\uvnc bvba.
The vnc_wrapper.bat parses vnc:// URL and starts UltraVnc using UNetLab server and port:
@ECHO OFFInstall the win7_64bit.reg in the Windows registry. This reg file configures bind the vnc:// URL and UltraVnc:
SET S=%1
SET S=###%S%###
SET S=%S:"###=%
SET S=%S:###"=%
SET S=%S:###=%
SET S=%S:vnc://=%
start "VNCViewer" "C:\Program Files\uvnc bvba\UltraVNC\vncviewer.exe" -connect %S% -disableclipboard -shared
Windows Registry Editor Version 5.00Now both telnet:// and vnc:// URLs should be openable using browser on Windows.

==== UNL Update
apt-get update==== Add some IOS
apt-get -o Dpkg::Options::="--force-overwrite" install unetlab
....
unetlab is already the newest version.

==== And yes, because IOL uses half duplex, we expect a musmatch error:
*Mar 1 00:02:54.535: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on FastEthernet0/0 (not half duplex), with R3 Ethernet0/0 (half duplex).
===== Idle-PC and 100% CPU for dynamips
http://www.unetlab.com/2014/11/adding-dynamips-images/
$ dynamips -P 7200 -t 7200 /opt/unetlab/addons/dynamips/c7200-adventerprisek9-mz.124-24.T5.image
Wait for the following line on the console:
Would you like to enter the initial configuration dialog? [yes/no]:
After few more seconds press CTRL + ] then i. Dynamips will show suggested Idle PC values:
Please wait while gathering statistics...
Done. Suggested idling PC:
0x606e0000 (count=64)
0x60210c60 (count=51)
0x606de3f0 (count=63)
0x606df838 (count=60)
Restart the emulator with "--idle-pc=0x606e0000" (for example)
0x6160dec4
Modify this in
/opt/unetlab/html/templates/c7200.php
Select one and restart dynamips with the IDle PC value:
dynamips -P 1700 -t 1710 --idle-pc 0x80369ac4 /opt/unetlab/addons/dynamips/c1710-bk9no3r2sy-mz.124-23.image
If CPU usage is lower, then a good Idle PC value has been found:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
3598 root 20 0 346700 125328 109828 S 5.3 25.3 0:03.98 dynamips
If CPU is still busy, then another value must be tested.
