Buffalo LS-QVL root access

Get the updated acp_commander.jar from Github
https://github.com/1000001101000/acp-commander

All needed files are in place, just needs some tweaking.. As with everything-Buffalo, I don’t know if it survives a reboot.

java -jar acp_commander.jar -t 192.168.0.10 -pw AdminPassword -c "(echo newrootpass;echo newrootpass)|passwd"
java -jar acp_commander.jar -t 192.168.0.10 -pw AdminPassword -c "sed -i 's/PermitRootLogin/#PermitRootLogin/g' /etc/sshd_config"
java -jar acp_commander.jar -t 192.168.0.10 -pw AdminPassword -c "echo 'PermitRootLogin yes' >>/etc/sshd_config"
java -jar acp_commander.jar -t 192.168.0.10 -pw AdminPassword -c "sed -i 's/root/rooot/g' /etc/ftpusers"

or

java -jar acp_commander.jar -t 192.168.0.10 -pw AdminPassword -s

then execute the same commands in the shell:

(echo newrootpass;echo newrootpass)|passwd
sed -i 's/PermitRootLogin/#PermitRootLogin/g' /etc/sshd_config
echo "PermitRootLogin yes" >>/etc/sshd_config
sed -i 's/root/rooot/g' /etc/ftpusers

Error message “pam_listfile(sshd:auth): Refused user root for service sshd” in /var/log/messages during my first login attempt
The last command above is there because root login was denied using this file (/etc/ftpusers) as a list of users to deny access in /etc/pam.d/login (or /etc/pam.d/sshd).
I found the hint to theck the pam.d configuration here (after checking the logs for any reason to the login error):

Since I wrote this note, I went over to installing Debian on my LS-QVL, so I can no longer verify each of the steps taken to gain root access.
