How can I determine the IP address of Proximo add-on Heroku? I looked at the following link https://devcenter.heroku.com/articles/proximo but could not figure it out.
heroku config | grep PROXIMO_URL
PROXIMO_URL: http://proxy:password#proxy-12-34-45-56.proximo.io
so your ip address would be 12.34.45.56

Run a dig command on the hostname you want to test against and add the resulting IP address in your hosts file with the public hostname.
I am trying to generate certificate for my domain. I can ping my domain but still getting error. I have added inbound firewall rule to my digital ocean server to accept port 80 on ipv4 and ipv6 as well. Not sure what is wrong. [Note: my nginx server is not running as I cannot get the certificate]
https://community.letsencrypt.org/t/invalid-response-404-nginx-docker-container/102525
My domain is: www.1040nra.com
I ran this command: sudo certbot certonly --staging --webroot -w /root/dt-app-data/ -d 1040nra.com -d www.1040nra.com
It produced this output:

To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
My web server is (include version):
The operating system my web server runs on is (include version): ubuntu 18.04
You seem to have solved the problem yourself.
This is because the certbot domain cannot verify the DNS A record.
Make sure your domain address is directed to your server's ip address.
If you made the dns change 'recently', it may take some time to delete the old ip address.
https://www.whatsmydns.net/
Check here, there should only be one IP address and this should be your server's IP address.
Make sure ports 80 and 443 are open by running the command below:
sudo ufw status
If port 443 is not open, then run the command bellow to allow port 443:
sudo ufw allow https
Issue: The issue is your domain might be not pointing to your Cloud host IP and DNS setup
Solution:
You have to map your domain and IP in-network option tab A
Once you did the mapping then you have to setup DNS on where you have purchased the domain website.
Then check by entering your domain name on this web site www.whatsmydns.net showing your IP address or not
If Yes then you create the certificate
Go to the https://www.whatsmydns.net/
Enter your host name
You set the type A
Make sure that there is the same IP everywhere
You set the type AAAA
Make sure there are no AAAA entries
AAAA are IPv6 entries.
If the addresses for AAAA are present, make a request to this IPv6 address
#example curl [43ff:0c89:eb10:4c06:c90e:4b7d:64e5:fbe1]
curl [your IPv6]
If you get an error, then the address does not point to your site. Accordingly, there is a difference between IPv4 and IPv6.
Solution: delete the domain zone type AAAA
I have a server(AWS) to which I have ssh access.
There is a service(supervisor) running on this service on port 9001 whose web view can be accessed through 127.0.0.1:9001 had it been a local machine.
But since it is not a local machine, how do I access it?
I got the ip address of the machine using ifconfig | grep inet and then tried accessing it through https://172.11.11.1:9001/
Bit dint work.
When I tried wget https://172.11.11.1:9001/ it shows
Connecting to 172.31.19.8:9001... and hangs there.
I have added the following line in my supervisor conf file.
[inet_http_server]
port = *:9001
Can someone please help me with this?
This is more of a server config question. You'll most likely find your AWS access properties allow connections on post 22, 80 and 443 only. In AWS console you'll need to add a new security access group to allow port 9001 to be accessed.
Just try to figure out how to do ip spoofing in JMeter on my mac. What is done is that I created file which contains ip addresses somewhere in my subnetwork.
When I try to run thread JMeter shows me:
java.net.BindException: Can't assign requested address
Only my IP has ping. So, could you please advice me where I am wrong?
You can add an IP alias from Terminal application (it is under Applications -> Utilities) as
sudo ifconfig en0 alias 192.168.0.12 255.255.255.0
where:
en - is Network Interface name
192.168.0.12 - is the IP alias
Once you set up the alias, you can use new IP address in the "Source address" input
And HTTP requests will use that IP address as source one:
You can remove the IP alias when it is no longer required as
sudo ifconfig en0 -alias 192.168.0.12
See Using IP Spoofing to Simulate Requests from Different IP Addresses with JMeter guide for more detailed information on the domain.
I have a simple Ruby app hosted on Heroku. It is not Rails app, it only uses Rack and Sinatra and it is running on cedar-14 stack.
When I try to run heroku run console or heroku run bash it prompts:
! Heroku client internal error.
! Search for help at: https://help.heroku.com
! Or report a bug at: https://github.com/heroku/heroku/issues/new
Error: No route to host - connect(2) (Errno::EHOSTUNREACH)
Also, when I try to telnet as suggested here It prompts just the same
$ telnet rendezvous.heroku.com 5000
Trying 50.19.103.36...
telnet: Unable to connect to remote host: No route to host
and
$ telnet s1.runtime.heroku.com 5000
telnet: could not resolve s1.runtime.heroku.com/5000: Name or service not known
I'm not premium Heroku user.
Can I get that One-Off dyno and If I can how?
