Specify Host for User in docker compose file

I’ve started messing with Docker and the MySQL 5.7 image, and have created a docker-compose.yaml file to quickly bring up a DB instance with the root password set, a new user & password created, and a new database. When I log in to the new DB, I see that the new user is set with a host of %. I would like to be able to set this to a host of my choice in the yaml, but I can’t find any docs or notes on what environmental variable to specify in the docker-compose file.

Thoughts about how to accomplish this? I did attempt to set MYSQL_USER: dbadmin@host but this just created the user as dbadmin@host with the host still set to % in MySQL.

Remote host identification has changed – How do I know if it’s an attack or not?

When connecting using SSH to a shared hosting provider I’m regularly using, I got this message today:

WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host [xyz.example.com]:2222 is 2b:6b:ec:d3:c0:fe:fb:40:11:fe:4b:73:03:17:6b:89. Please contact your system administrator. Add correct host key in C:\Users\Example.ssh\known_hosts to get rid of this message. Do you want to delete the old key and insert the new key?

I clicked “No”, because I have no idea if it’s a legitimate change or an actual attack.

How would I find out? The hosting provider is using CPanel, if it helps.

What title do priests of the Sovereign Host use?

Eberron Campaign Setting and Faiths of Eberron refer to the faithful of the Sovereign Host as “vassals,” and indicate that the various congregations of vassals are led by “priests,” in a mostly-decentralized manner. Quite a lot of detail is offered on what it means to be a priest, how one becomes one, and so on, but one thing seems conspicuously absent:

How do you address one?

Most real-world clergy have a particular title used with their names to indicate their status, and I assume the same is true in Eberron as well, but I can’t seem to find anything saying what those titles are. The Church of the Silver Flame has quite a lot of detail (being a very-thinly veiled proxy of the Catholic Church, it uses “Father,” “Bishop,” and “Cardinal”), and other cults are small enough that I’m not terribly worried about them, but the Sovereign Host is the majority religion for most of the continent: it’s a big deal.

So is there anything out there I’m missing that describes the naming? Even just a named example priest NPC, so that I can see how they’re named in a statblock, would be useful, but I can’t find even that.

Can the Host Header be used to hide the existence of a service?

Imagine a web server running on 93.184.216.34, usually reachable via the public DNS entry example.com. Web servers usually allow the distinction of multiple “virtual” servers, based on the Host header received via the HTTP request.

Now imagine the same web server would offer a different service when requested via cx6wdffpuik997eljf6d878i6f3np4207ne30vyjsvhpra69, which was not a public DNS entry, but rather done via a local DNS server or a modified hosts file.

Would this effectively hide the existence of the hidden service? Is this done in practice?


Note: I am aware that this alone should not be used to secure the service. Authentication via client-certificates would be done in addition.

Host not connected to my router shows up in a nmap scan

After scanning my local network with nmap, this host shows up listed as a nmap result but it is the only host that shows on nmap that is not listed as a client on my router list of connected devices.

❯ nmap 192.168.0.xxx -A                                                                                                                                                                  Starting Nmap 7.80 ( https://nmap.org ) at 2020-04-21 14:33 -03 Nmap scan report for 192.168.0.xxx Host is up (0.0056s latency).

What exactly about this host might be causing it to show on nmap in my local network if its not connected to my router?

nmap script “smb-os-discovery.nse” does not output information about the host OS?

I was following this Lynda course.

https://www.linkedin.com/learning/ethical-hacking-enumeration/enumerating-smb-from-linux-episode-1

The instructor used this script to detect the OS of the target system.

nmap --script /usr/share/nmap/scripts/smb-os-discovery.nse 192.168.56.3 

I have a OWASP box vm and Kali Linux running in a host only network in VirtualBox.

192.168.56.3 is the IP of OWASP. I’m running the above command from the Kali linux.

The output is

Starting Nmap 7.70 ( https://nmap.org ) at 2020-04-21 01:00 CDT mass_dns: warning: Unable to determine any DNS servers. Reverse DNS is disabled. Try using --system-dns or specify valid servers with --dns-servers Nmap scan report for 192.168.56.3 Host is up (0.00045s latency). Not shown: 991 closed ports PORT     STATE SERVICE 22/tcp   open  ssh 80/tcp   open  http 139/tcp  open  netbios-ssn 143/tcp  open  imap 443/tcp  open  https 445/tcp  open  microsoft-ds 5001/tcp open  commplex-link 8080/tcp open  http-proxy 8081/tcp open  blackice-icecap MAC Address: 08:00:27:FE:F6:AC (Oracle VirtualBox virtual NIC) 

A port scan is done but the OS detection part in the script is not performed.

For example this is the output shown in the tutorial
