It’s not completely obvious that upgrading the partition means upgrading the OS on the controller. Use this if the Web UI gives you an error about running out of space.
To upgrade partition 0 in enable mode:
copy tftp: <IP ADDRESSS> <FILENAME> system: partition 0
copy tftp: 220.127.116.11 A800_18.104.22.168_23915 system: partition 0

copy sftp startup-config user <username> <IP Address> <Path to File>
copy sftp startup-config user alexkuo 22.214.171.124 /var/home/alexkuo/switch-import.cfg
Export Switch Configuration

You can download here the updated registry entry for opening the ASP.NET Development Web Server using context menu in Explorer. The path has been updated to use Visual Studio 2015’s development web server.
This is used to quickly open a web server in a directory. After merging the registry, just do the following:
- Open explorer and navigate to the target directory
- Right click and select the ASP.NET Web Server Here option
I have not tested this in Windows 10.
When setting up the guest network between an IAP with ClearPass, the older guides direct the user to setup a PreAuth role for guest and deny all traffic.
It’s assumed a firewall exception or something similar is automatically put into the IAP firewall rules to let the IAP, client, and the ClearPass server communicate, but this isn’t the case currently. In addition to denying traffic to all servers, you need to add additional rules to let the client communicate with ClearPass AND the IAP – or else radius requests will fail.
The PreAuth role looks similar to the following:
- 192.168.99.111 is the IAP’s Virtual Controller
- 192.168.99.103 is the ClearPass server
I needed a bash script to delete empty directories, excluding the parent directory. The following does this:
find /home/alex/target mindepth 1 -maxdepth 1 -type d -empty -print0 | xargs -0 rm -R
And the crontab that does this every few hours
0 */12 1-31/2 * * find /home/alex/target -mindepth 1 -maxdepth 1 -type d -empty -print0 | xargs -0 rm -R >/dev/null 2>&1
After reading through a bunch of troubleshooting threads, the following:
- Runs a shell script via cron
- SSH into a remote server using a SSH key for a password
- Executes Rysnc with the options to delete source files after download, and skip files with the extension .part
/usr/bin/rsync -havzPe 'ssh -i /home/alex/.ssh/id_rsa' --rsync path='/usr/bin/rsync' --remove-source-files --exclude='*.part' --stats email@example.com:/home/alex/target /home/alex | /usr/bin/mail -s 'Rsync Output' root
Link Explain Shell
Crontab consisted of the following:
0 */2 * * * /home/alex/sync.sh >/dev/null 2>&1
This runs the shell script every 2 hours. This was created using a this crontab generator.
Generating a SSH key for passwordless SSH login and exporting it remotely is explained here.
Generate the keys on your host server:
ssh-keygen -t dsa
Export the keys to the target server:
ssh-copy-id -i ~/.ssh/id_dsa.pub ross@remotehost [or enter ip address instead of hostname, e.g."remotehost"]
Configure email server so mail command works.

Google’s Protobuf code generator uses an API that many .NET developers may find a bit different than the usual MO.
An alternative to Google’s Protobuf implementation is Marc Gravell’s protobuf-net library, which uses an implementation that may make more sense to .NET developers. However, the code generator for this library is nowhere to be found in the nuget package. You can download it here.
The following is an example of executing the CLI tool
protogen -i:input.proto -o:output.cs
The example found on the csharp tutorial page doesn’t work. Instead do the following
- Open visual studio, open nuget command line, type :Install-Package Google.ProtocolBuffers , link : ProtocolBuffers 188.8.131.525
- Find Package/Google.ProtocolBuffers.184.108.40.2065/tools/ProtoGen.exe
- Use command line, type : ProtoGen.exe addressbook.proto -output_directory=C:\trash
Source: Stackoverflow Post
Marc Gravell has an online tool for generating C# code from a .proto file.
Edit the /etc/samba/smb.conf file and add something similar
path = /samba/secured
valid users = @smbgrp
guest ok = no
writable = yes
browsable = yes
Afterwards, save the conf file and restart samba
sudo service smbd restart
