Pixel Doubling / HiDPI display support for BurpSuite

Running BurpSuite on a HiDPI display, and that makes the interface window tiny and unreadable?

Just set the _JAVA_OPTIONS environment variable so that it includes -Dsun.java2d.uiScale=2

On Linux, you can edit the BurpSuiteCommunity executable shell script wherever it's been installed, to include the following line near the top (below the #! line, though!):

export _JAVA_OPTIONS="-Dsun.java2d.uiScale=2"

Automatically start a single instance of ssh-agent for all terminal sessions to share (bash)

Installation

  1. mkdir -p ~/.config && touch ~/.config/ssh-agent.pid
  2. Paste the contents of ssh-agent-manage.sh into your .bashrc or .bash_profile or similar
  3. killall -9 ssh-agent
  4. Start a new terminal session (note: old sessions will not see ssh-agent, only new ones)

Details

This snippet, when included in .bashrc, will ensure that your session has a working ssh-agent with all your ssh keys loaded into it. It does this without creating separate ssh-agent processes by:

open-vm-tools and VMWare Shared Folders for Ubuntu guests

(NB: adapted from this Ask Ubuntu thread -- tested to work on Ubuntu 16.04 LTS through Ubuntu 22.04 LTS (Jammy).

Unlike using VMWare Tools to enable Linux guest capabilities, the open-vm-tools package doesn't auto-mount shared VMWare folders. This can be frustrating in various ways, but there's an easy fix.

TL;DR

Install open-vm-tools and run:

sudo mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other
