Sshbackup script

Installing and Using OpenWrt
1

I have a dozen openwrt edge endpoints and lost the configs to one during an upgrade..

so I came up with something..

change the username, password, and destination..

update cron, change perms, etc..

YMMV

#!/bin/sh

if ! [ -x "$(command -v sshpass)" ]; then
  echo 'Error: sshpass is not installed.' >&2
  opkg update
  opkg install sshpass openssh-client
fi

export SSHPASS='sshpasswordhere'

umask go=
sysupgrade -b /tmp/backup-${HOSTNAME}-$(date +%F).tar.gz

sshpass -e scp -o "StrictHostKeyChecking no" /tmp/backup-${HOSTNAME}-$(date +%F).tar.gz useraccounthere@192.0.2.254:/exports/

rm /tmp/backup-${HOSTNAME}-$(date +%F).tar.gz


# service cron enable
# service cron start
# crontab -e
# 42 00 * * * /etc/sshbackup
# chmod 755 /etc/sshbackup

size of files fwiw..

16.0K /usr/bin/sshpass
184.0K /usr/libexec/scp-openssh

You know that you leak the password to any mitm without host key checking?

And you don't have a script which builds unique pre-configured firmware for all of them?
