Autossh

• attivare autossh, ossia un tunneling ssh su macchina pubblica per

permettere l'accesso remoto di amministrazione; infatti la connesione tramite wifi o ethernet o GSM non espongono un ip pubblico (almeno senza fare un reindirizzamento di porta):

yum install autossh da root:

ssh-keygen
ssh-copy-id 

/usr/lib/systemd/system/autossh.service

[Unit]
Description=Autossh tunneling
After=network.target

[Service]
#User=ttn
#Group=ttn
WorkingDirectory=/root
#ExecStart=/usr/bin/autossh -M 5023  -N -R 5022:localhost:22 pat1@ttn.rmap.it
ExecStart=/usr/bin/autossh -M 0 -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" -N -R 5022:localhost:22 <user>@<remotehost>
SyslogIdentifier=autossh
Restart=always
RestartSec=30

[Install]
WantedBy=multi-user.target

systemctl daemon-reload
service autossh start
chkconfig autossh on

ora dalla macchina remota si può fare:

ssh root@localhost -p5022
