How to automatically obtain keys in Evolution for e-mail recipients? (key discovery)

I am using the PIM Evolution 3.22.6 for e-mail and contacts. For encrypting e-mails gpg (GnuPG 2.1.18) is used by Evolution.

How can I configure my system such as when I compose an e-mail the PGP key for the recipients are automatically retrieved from key servers and added to my keyring?

For example when I try to send an e-mail to a recipient, which is not in my keyring I get the following error message: gpg: <edward-en@fsf.org>: skipped: No public key

In case I run – outside of Evolution – gpg --search-keys edward-en@fsf.org a key is successfully found. Is there any way to tell Evolution to deal with the search?

How to conduct product discovery process in the B2B

There are some reasons why the discovery process for B2B (mid and enterprise) seems to me much more complicated compared to B2C:

  • Multiple feedbacks: multiple personas can use the same product
  • Low incentive to share internal problems
  • Long feedback cycle
  • Small market (#): some markets are made up of less than 50 companies
  • Strongly based on relationship
  • Domain complexity: some B2B niches are very specific and technical

Given this context, what would be a good discovery process techniques and approaches for B2B?

NMAP discovery scan reporting host offline, pinging the same host gets ICMP responses

I ran an nmap -sn scan on a host, and nmap reported the host as down. I then pinged the same host with ping and got ICMP responses. I’m confused, because I was sure that -sn among other things, did an ICMP echo request.

Output from my two commands:

~ $   nmap -sn 192.168.1.237   Starting Nmap 6.40 ( http://nmap.org ) at 2016-08-16 09:35 BST Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn Nmap done: 1 IP address (0 hosts up) scanned in 3.00 seconds  ~ $   ping 192.168.1.237 PING 192.168.1.237 (192.168.1.237) 56(84) bytes of data. 64 bytes from 192.168.1.237: icmp_seq=1 ttl=128 time=9.82 ms 64 bytes from 192.168.1.237: icmp_seq=2 ttl=128 time=5.25 ms 64 bytes from 192.168.1.237: icmp_seq=3 ttl=128 time=2.95 ms 64 bytes from 192.168.1.237: icmp_seq=4 ttl=128 time=9.10 ms ^C --- 192.168.1.237 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3004ms rtt min/avg/max/mdev = 2.957/6.785/9.826/2.810 ms 

Any ideas why NMAP could be confused? I’m running the scan from my Ubuntu 16.04 box, the target is a Windows 10.

Stats for homunculus created by Alchemist with Promethean Disciple discovery – how to get it buffed up, RAW?

One of my ex players (ex as we’re switching DM currently, she is still active) wanted to create a homunculus. She took Promethean Disciple because, for some reasons, Promethean Alchemist did not appeal to her.

Now she is level 8, and time, money, access to spells, blood and body parts are not of any particular concern to her at this point in the campaign. And man, what a collection of preserved body part she has! Prehensile tongues, wings etc.

The goal is to have homunculus (or homunculus-themed flesh golem) that is small or medium, has wings and boggart (frog-humanoid) tongue, and probably can “cast” one or two alchemical effects 1/day, too.

In my game it would not be a problem at all, given all the time and effort she put into it in game*, but because we’re transiting between DMs, I wanted to ask you, how close can we get to do this, RAW?


* Like, most of her character doings was experiments with flesh alchemy in order to build herself a servant she envied Promethean Alchemists. Actual 3/4 of her roleplay, honestly!

how to check if network discovery is on using powershell?

I have just built a new server – windows server 2016

when trying to access its c: drive from any other server I was getting this error:

enter image description here

The I changed this settings:

enter image description here

and all is working fine.

question:

Is there a way to check if network discovery is on using powershell?

otherwise, when they give me another server, how can I check for this setting?

How to discover discovery service

We are designing an architecture of a high availability distibuted system and we are considering server side vs client side service discovery. There is one problem, I need to solve – how is it possible to discover the Discovery Service (Eureka/Zookeeper/NGINX…)? Is there any way, how not to hardcode/hardconfigure the Discovery Service address?

Is really NMAP uses ping packets to consider Host discovery?

I run this command nmap -sn 192.168.0.2 for only Host discovery. And then I started wireshark to see what will going to happen.

I thought It would send ICMP echo req, but the results was very different.

It uses ARP protocol not ICMP. Even I didn’t see any single entry of ICMP in wireshark.

Am I missing any thing?

See the results.
