Going to look into some email security products, mainly aimed at enteprises. Gateway implementation is main focus. This is in progress and just a list of products atm.

During livestreaming with wirecast with RTMP protocol we got some issues with drops and disconnects/reconnects. In the log for wirecast we saw some messages at random times. The log is found in the appdata catalog for the user running wirecast (in our case C:\Users\{username}\AppData\Roaming\Wirecast}. The messages found when the session was disconnected:
Feb 12 22:51:54 A: Start OK: sample=4, channels=2, type=2
Feb 12 22:54:12 N: onStatus: code="NetConnection.Connect.Closed" type="status" desc="" details=""
Feb 12 22:54:12 A: Network connection severed: -1301

Right after those messages the connection was reestablished. Was experiencing some choppy video aswell.

Tried making a whitelist in the DP-1006 like this:
In the submenu DDoS->Whitelist
Filled in SrcNetwork=ip of the wirecast client, DstNetwork=ip of the RTMP server, Protocol=TCP

Did a test streaming after this and after 30 minutes+ there was no more drops.

Guess this did the trick..

Check information registered in dns: nslookup –type=srv _vlmcs._tcp.subdom.domain.rootdom

Windows use space on systemdrive for almost never used installation files. You can easily move those from your expensive SSD to a cheaper datadisk:

Run cmd as Administrator, and use the following commands:
mkdir D:\Junctions\C\Windows\
move C:\Windows\Installer D:\Junctions\C\Windows\
mklink /J C:\Windows\Installer D:\windows\installer

You can also free up space by:

If you have a cisco network and not using software tools who logs status for your switchports you can still find where your device is connected without physically going to the location checking patching.

You will need a source and a destination mac address.

• Source mac address
  • The source mac address isn’t that important, just do a sh mac address table vlan 5. Find a random mac address on the same vlan as the device you are looking for.
• Destination mac address
  • I usually find this by checking the dhcp server or asking the user for the information. It might be printed on a label on the device or if it’s a windows computer you find it with ipconfig /all under Physical Address.

When you got source and destination mac address you can run the command: traceroute mac {source mac} {destination mac}. The output will tell you something about where both source and destination mac is connected and the path between them. Example:

Traceroute mac aaaa.bbbb.cccc dddd.eeee.ffff
Source aaaa.bbbb.cccc found on switch10
1 switch10 (172.32.0.10) : Fa0/40 => Gi0/1
2 switch13 (172.32.0.13) : Gi0/2 => Gi0/1
3 switch19 (172.32.0.19) : Gi0/2 => Gi0/1
4 switch31 (172.32.0.31) : Gi0/2 => Fa0/38
Destination dddd.eeee.ffff found on switch31
Layer 2 trace completed

If you need more details, you can add detail after the command.

Clean up volumes, moving data first

1. Set volume readonly: upd vol /tsmdata/stg1/filepool/01301.dsm acc=reado
2. Move data from the volume: move data /tsmdata/stg1/filepool/01301.dsm w=y
3. Delete the volume: del vol /tsmdata/stg1/filepool/01301.dsm
4. Delete the volume from the underlying file system (linux example here): rm -f /tsmdata/stg1/filepool/01301.dsm

All this could be scripted if multiple volumes should be cleaned up to free space on underlying file system.

Backup database

ba db t=f dev={deviceclass} (example: file_dbb)
