MBG : How to remove “revoked” certificates

Although i dont believe it does any harm i have wanted to remove the revoked certifcates from the certifcate management web page on the MBG

As you see above i have already removed mine

To do this simple find the revoked PEM files under

/home/e-smith/certmgmt/revoked

If you want to be specific you can search for the actual file or just delete all in the “revoked” folder

You can either access this folder with putty or via Winscp

If you dont know how to access the MBG via putty see my post here

How to : Edit large wireshark files with “editcap”

Wireshark does not play well with large pcap files. I read somewhere you need 1GB of RAM for 1 GB of file.

I recently needed to review the contents of a 30gb pcap file and wireshark refused to open it.

Few minutes of googling and i came accross this useful command

editcap. Its part of wire shark, located in the installation directory

editcap -h will give you some useful information

I found this post useful

Here is my example for extracting one days worth of capture

“C:\progam files\wireshark\editcap.exe” -v -A “2019-30-11 08:00:00” -B “2019-11-30 18:00:00” c:\input.pcap d:\output.pcap
