Unable to Connect from New ISP
I am having an issue connecting to my linode. Traveling to my girlfriend's parent's house, I am unable to connect via PuTTy, MySQLWorkbench, or Netbeans (SFTP). My login configurations haven't changed, they were working fine yesterday using Delta WiFi on my flight, and they even work now if I connect via mobile hotspot.
I tried running
nmap -p 21,22 <IP Address>
with my current IP address in the web GLISH, and I got:
Starting Nmap 6.47 ( http://nmap.org ) at 2019-10-27 15:42 GMT 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 3.04 seconds
Please advise on how to fix. Do I need to whitelist this IP address or something? And if so, how do I do that?
Sorry to see you're having problems connecting to your Linode. What you're describing sounds like a peering issue with the local ISP. You probably need to open a Support Ticket. However, before you open it, we are going to ask you to run MTR reports so that we may further investigate this issue. So that we can speed up the process, could you please provide the output of an MTR report from your location to your Linode, as well as the reverse?
While logged into your Linode:
mtr -rwzbc100 <desktop.IP.Address>`
While logged into your desktop:
mtr -rwzbc100 <linode.IP.address>`
More information on generating and interpreting MTR reports can be found here.
If you cannot currently access your Linode via SSH, you can use LISH (Linode Shell) to issue the reverse report from your Linode. More information about using LISH can be found in our guide.
The report will take a few minutes to run. Then when you finish copy-paste, the outputs into a Support Ticket. Usually, if there's a peering issue, the hops won't leave our data center or will get stuck going to the Linode. We need to see where the problem is located. If the test running from your Linode to you is successful, then there is an issue with the local ISP, and you will need to reach out to them. If the report going to you from the Linode doesn't leave the data center, then there is a peering issue on our side, and our network team will see what they can do to help.
I hope this helps. Feel free to open a Support Ticket with any questions.
