To get AWS CLI working in Cygwin: Install “python2-pip” with the Cygwin installer (and accept whatever dependencies it brings) Run “pip2 install awscli“ See what you have: “aws –version“, and continue with the usual “aws configure” procedure. Using AWS CLI is not very fast in this setup however. For example, showing specific Virtual Private Gateway […]
How to Fix GoToMeeting or Skype for Business on Second Monitor
[Update on 2018-08-31: The instructions below are probably not useful anymore after several Windows 10 or other software updates. Things look much better nowadays, even though many software still have problems with differing font scaling factors. I still feel sorry for the many developers out there who apparently don’t have sufficient possibilities to test software […]

Sending Twitter DMs in Zabbix Actions
When configuring actions in Zabbix for example for problem alerts, there is a built-in method for sending email notifications. Here are the instructions for sending alerts as Twitter direct messages.

majornetwork.net Is Now TLS-Enabled
I just enabled TLS in majornetwork.net. Everything seems pretty normal, and old http links should still work, redirecting to https. If you notice anything breaking up, let me know. Oh, and don’t report “not working with IE 6 on Windows XP”: It’s not me, it’s you.
IPsec VPN Tunnel between F5 BIG-IP and Juniper SRX
This post is an example of configuring an IPsec tunnel with F5 BIG-IP. In the diagram below the IPsec tunnel is configured between SRX210 (Junos 12.1X47-D20.7) and F5 BIG-IP (11.6.0 HF5-ENG11). F5 BIG-IP is connected here in one-arm setup. The SRX240 is not “an interesting device” in this demonstration. It is just a firewall and […]

There is a lot of documentation in the site but somehow I felt the material was hard to absorb. In this post I describe the reference implementation I managed to complete with SoftEther. […]
Juniper SRX IPsec LAN-to-LAN VPN Part 2
This is the part 2 of my Juniper SRX IPsec LAN-to-LAN VPN posts. In part 1 we had a simple LAN-to-LAN VPN with only one subnet in each site. In this post we have two subnets in Their Site to illustrate the VPN configuration options. Here is the topology for this post. Their Site is […]
Juniper SRX IPsec LAN-to-LAN VPN Part 1
In this post I will show two flavours of configuring a LAN-to-LAN IPsec VPN tunnel with Juniper SRX: policy-based and route-based. I have been under impression that those ways are mutually exclusive so that only one way is valid for a given endpoint in the opposite side. How wrong have I been. Here is the […]
