Is there a way to increase the rate at which Gmail fetches mail from another account? – Web Applications Stack Exchange

Posted by jpluimers on 2021/02/05

[WayBack] Is there a way to increase the rate at which Gmail fetches mail from another account? – Web Applications Stack Exchange got a nice follow-up on Twitter:

This is way better than suggestions from the past: increase the frequency in which email arrives at the POP3 account.

bash – How to get the primary IP address of the local machine on Linux and OS X? – Stack Overflow

Posted by jpluimers on 2021/02/05

[WayBack] bash – How to get the primary IP address of the local machine on Linux and OS X? – Stack Overflow (thanks [WayBack] Collin Anderson!):

I tried on OS X 10.13.6 (macOS High Sierra) and these two work fine:

ip route get 1 | awk '{print $NF;exit}'

and

ip route get 8.8.8.8 | head -1 | cut -d' ' -f8

The first one needs the $ back-slash escaped as bash alias; the second does not need that.

i haven’t used nmap much except to scan my home network for fun so if i missed something really important i’d love to know!

also i need to find space in there somewhere for “if you don’t run nmap as root it can’t send icmp (ping) packets, it’s better to run nmap as root”

also be careful when nmapping in a network you don’t administer! it’s a popular hacking tool so using nmap is often discouraged / banned. i made all of the examples in this comic “nmap scanme.nmap.org” and “nmap your home network” for a reason :)

There are are quite a few interesting comments on the thread:

And it taught me about scanme.nmap.org: [WayBack] Go ahead and ScanMe!

Hello, and welcome to Scanme.Nmap.Org, a service provided by the Nmap Security Scanner Project and Insecure.Org.

We set up this machine to help folks learn about Nmap and also to test and make sure that their Nmap installation (or Internet connection) is working properly. You are authorized to scan this machine with Nmap or other port scanners. Try not to hammer on the server too hard. A few scans in a day is fine, but dont scan 100 times a day or use this site to test your ssh brute-force password cracking tool.

Thanks
