[Solved] Root password

[Egidio]

Hello,

I installed Arch Linux on a Raspberry PI 1. I tried to connect via ssh using root:root and alarm:alarm, but I cannot login. Is there any enabled user to login via ssh?

Thanks,

Egidio

What is the output when you attempt to connect? I believe (not 100%) that sshing as root has been disabled upstream for some time. It could be that Arch ARM modifies the config file to allow it though.

Hi!

It simply says "permission denied".

$this->bbcode_second_pass_code('', '
[egidio@arch ~]$ ssh -l root 192.168.1.94
root@192.168.1.94's password:
Permission denied, please try again.
root@192.168.1.94's password:
')

$this->bbcode_second_pass_quote('graysky', 'I') believe (not 100%) that sshing as root has been disabled upstream for some time.

I tried with the "alarm" password:

$this->bbcode_second_pass_code('', '

[graysky]

Are you sure 192.168.1.94 is the RPi? If so, are you sure you're typing the default password correct? If both are true, I cannot explain. From where did you obtain the image?

[Egidio]

From the official website. I'm pretty sure that's the right IP address. The other arch is my laptop.

[graysky]

Not sure what to tell you... alarm/alarm worked for me.

[WarheadsSE]

It's clear from the debug
$this->bbcode_second_pass_code('', 'debug1: Local version string SSH-2.0-OpenSSH_7.3
debug1: Remote protocol version 2.0, remote software version OpenSSH_6.7p1 Raspbian-5+deb8u3
debug1: match: OpenSSH_6.7p1 Raspbian-5+deb8u3 pat OpenSSH* compat 0x04000000
')

Hint: the default hostname with ALARM is "alarmpi"

[graysky]

Ha! I read over that but thought he was connecting out from the Raspbian host to the Arch ARM box...
