[SOLVED] ssh connection problem

Pedroski · 06-15-2019, 03:16 AM

I'm trying to learn ssh. I have a little webpage on goDaddy.

I generated keys.

Quote:

ssh-keygen -t ed25519 -f ~/.ssh/godaddy_ed25519 -C "My ssh key"

First, I tried to login, I've managed this before:

Quote:

pedro@pedro-school2:~$ ssh Pedroski@www.xxx.yyy.zzz

It asks me for a password:

I tried my goDaddy User login password. No joy.
I tried my cPanel login password. No joy.
I logged in, changed the cPanel password, tried ssh login with the new PW again. No joy.

Now it blocks me. Too many unsuccessful login attempts I suppose.

Quote:

pedro@pedro-school2:~$ ssh Pedroski@www.xxx.yyy.zzz
ssh_exchange_identification: read: Connection reset by peer

This is only a cheap and nasty goDaddy shared host, maybe that is the problem.

What password do I need to give in response to ssh?

My goDaddy username login password, or my cPanel password.

Both don't seem to work.

When you ssh into a server with a user@server, you'll need the password for the user -- Pedroski in this case which, I suspect, is not capitalized...try pedroski -- very unusual to use mixed case for usernames.

Thanks.

Pedroski is not the right name. The right name is my cPanel login name, a jumble of letters and numbers.

I understand that goDaddy might block me after repeated failed login attempts.
I thought, if I wait a bit, sleep on it, maybe it will work again. Wrong!

From goDaddy help chat, another customer with the same problem getting advice:

Ok, your next move would be to make sure that your IP is not blocked...

After about 45 minutes on the phone they figured it out and got my account unblocked. Thank you very much for the advice.

Someone said, go to your cPanel, switch ssh off, then on again, should unblock it. That did not work for me. I think I will get an account at Digital Ocean!

but my own computer also refuses me?

Quote:

pedro@pedro-school2:~$ ssh localhost
ssh: connect to host localhost port 22: Connection refused
pedro@pedro-school2:~$ ssh pedro@localhost
ssh: connect to host localhost port 22: Connection refused
pedro@pedro-school2:~$ ssh test@localhost
ssh: connect to host localhost port 22: Connection refused
pedro@pedro-school2:~$

Tried as sudo, no go:

Quote:

pedro@pedro-school2:~$ sudo ssh test@localhost
[sudo] password for pedro:
ssh: connect to host localhost port 22: Connection refused
pedro@pedro-school2:~$

Reading more, I read that, if I connect from a different wifi, the ssh connection should succeed. Doesn't!

I called goDaddy help, the woman said, ssh is not blocked, but there was something weird about my ip here in China.
She connected to my webpage ip at goDaddy with Putty, which is ssh, I'm told. Not blocked.

I have an idea. Will this work?

I tried to upload a key. I remember seeing a message:

Quote:

pedro@pedro-school2:~$ ssh-copy-id -i ~/.ssh/goDaddy_ed25519 mycPanelusername@123.456.123.456
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/pedro/.ssh/goDaddy_ed25519.pub"

/usr/bin/ssh-copy-id: ERROR: ssh_exchange_identification: read: Connection reset by peer

pedro@pedro-school2:~$

Can I upload the ssh key by hand. If so, where should I put it?

Fixed it: seems it was the Great Firewall of China causing trouble again. After I connected to expressvpn, I uploaded the key fine:

pedro@pedro-school2:~$ ssh-copy-id -i ~/.ssh/goDaddy_ed25519 mycPanelusername@123.456.123.456
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/pedro/.ssh/goDaddy_ed25519.pub"

/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
mycPanelusername@123.456.123.456's password:

Number of key(s) added: 1

Now try logging into the machine, with: "ssh 'mycPanelusername@123.456.123.456'"
and check to make sure that only the key(s) you wanted were added.
