Serial Console Login "Login incorrect"

fouad_jh · 2013-01-24 10:41:19

Hi all

I just installed Arch Linux on x86 PC, I can login as root from the terminal using a keyboard.

I have configured Arch Linux to be able to use the console through USB to serial converter, I have configured all to communicate right, when I boot Arch Linux PC, while another PC connected through serial port, I get the login prompt, I use the other PC with the root user name and password, I get "loging incorrect" error

Am I missing anything?

Thanks

Hum well, I wrote the "GRUB2 and systemd" of the wiki

https://wiki.archlinux.org/index.php/Wo … nd_systemd

I personally have it configured with the first option i.e. setting up GRUB2 and letting systemd figure it out on it's own. I have no problem logging in as the root user, with no extra configuration.

What serial console program are you using, minicom?

add ttyUSB0 to /etc/securetty

Awe yes, that is the problem. I was thinking about the securetty file but forgot that he said it was a USB-to-serial adapter, so I figured "well ttyS0 should be in there..."

Hi, thanks for your replies, I just added it and worked fine. Thanks

How about SSH? is it something to do with SSH configurations? /etc/secyretty? or /etc/security/access.conf?

I will be trying to figure it out, but if you have come across it before, then will be handy.

Thanks

For SSH login, I had to un-comment "PermitRootLogin yes" in /etc/ssh/sshd_config

Thanks

No,
Do not allow root login from SSH.
Every robot and worm ever made hammers the root user account on every SSH daemon they can find. Login to SSH as a normal user and then use the `su` command to become the root user.

Thanks, for the purpose of what I am doing, is not really a big deal, but I agree with what you said, it would be much safer.
