This is why I configure my systems with /home as a separate partition. If you have not done this, you'll have to backup your /home/$USER (big USB keys are cheap), test the backup, reinstall, and restore.l

As I said in my answer, both lists of authentication methods are in the logfile, before any Next authentication method messages. You have shown a lig fragment of several keys failing in "publickey", and trying password next.

The first step in debugging ssh connections is to add the -v option to tour ssh command (ssh -v ...). Look at both the client's and server's lists of authentication methods. Only the authentication methods appearing in BOTH lists will work. If your desired authentication method fails, you'll know which server to "fix".

Your swap space is minuscule. 1/4 RAM size? You need 2xRAM. Also, avoid the use of upper case variable names. By convention, programs use uppercase names to control their actions. If you use upper case names yourself, you will, eventually, collide, and some program or script will flip out. This type of problem is very hard to solve.

waltinator

Do you have swap? free will tell you. If not, you need between 1xRAM and 2xRAM. Swap space must be contiguous, not fragmented. You may be encountering the dreaded OOM-Killer.

Telling us which remote procedure (RP) you "followed" doesn't help us help you for N reasons: 1) It's remote. Will the link exist tomorrow? 2) Reading the RP doesn't tell us how accurately you "followed" it. Did you suffer typos or missed lines? We have. 3) Reading the RP omits the error messages you got on your system. These error messages (and the commands that caused them) are key elements in any diagnosis.

Reread man NetworkManager.conf. Your dhcp=internal is what's preventing your system from getting a DHCP-assigned IP address from the router. No IP address, no TCP/IP communication.

Watch sudo journalctl --follow (or sudo tail -f /var/log/syslog) as you try to connect to the router.

And you assert that the above complex ( so complex that it's hard for you to type) command is good because it's a 1-liner? Make a script called "startup" in their $PATH, then that's all they'll have to type. You can use more than 1 line in startup.

What effect do you expect? The alias will be defined to the bash -c shell, which will then exit, forgetting everything. You could only use the alias within the bash -c operand. Also, one may separate commands with ";", rather than "\n".

Read man dhclient.conf and adjust the retry timeouts or use my script. Their server is overloaded by DHCP clients, or other stuff they're running on it, and doesn't respond in time. The only thing you can do is to set your retry timeout to a very low value (and try again real soon). IMHO (as a 50-year-career computer guy) this is a suboptimal way to run a DHCP server, but maybe they have reasons.

OK, they want you to re-lease your address every minute. This is not because of a shortage of IPv4 addresses. It's because they have too many clients for too few addresses in their DCHP address pool.

When "My ISP's support tested the connection on their device with my credentials and it worked fine for them" what timeout value did they get?

waltinator

Dec 27, 2017 23:28

The DHCP server tells its clients (you and others) to ask about their addresses again in 60 seconds. This will cause the server to be deluged with requests, and may cause it to be overloaded. "Reasobable" values are around 1500, but YMMV.
