SSH Client as a Quick and Dirty Port Scanner
by zitstif on Jul.22, 2022, under Posts
Since the ssh client is pretty ubiquitous and has been included with Windows 10 installations for the past couple years, I’ve discovered it can be a useful tcp port scanner if you use the verbose flag:
For Windows:
ssh -p 80 google.com -v 2>&1 | findstr Connect
ssh -p 80 -o ConnectTimeout=1 www.google.com -v 2>&1 | findstr Connect
debug1: Connecting to www.google.com [142.250.191.228] port 80.
debug1: Connection established.
kex_exchange_identification: Connection closed by remote host
As for your *nix systems, just use grep instead of findstr. I hope someone else finds this useful!
Domain Controller/Active directory over Meraki VPN fix
by zitstif on May.03, 2022, under Posts
If you have a Meraki setup that has Umbrella tied into it, and you can’t communicate properly with your *.local domain controller over the Meraki VPN, I have a potential fix for you. In my scenario, VPN clients could see the domain controllers and DC IP addresses were specified as DNS servers which would properly assigned to VPN clients. VPN clients could query DCs for external DNS names without any issues but any *.local communications or gpupdate related commands would fail. I troubleshooted it to the nth degree and discovered this fix:
Go to Security & SD-WAN, then to configure, and then to threat protection. Scroll down to the Umbrella protection section and specify your local domain name (mydomain.local) as an exception from being routed to Umbrella. Save your changes and hopefully this resolves your issue.
If you continue to have issues, double check that your VPN clients and see what DNS servers are getting assigned. Some individuals had to change the metric (hint lower the number, route print to find metrics of adapters).
