docker run --rm -it -p 80:5000 images/name (run and show terminal)

Connect to Container
docker exec -it docker_instance_id shell_in_container

Docker Save Images:
​docker save images_name > images_name.tar
docker save -o images_name.tar images_name


Docker Load Images:
docker load < test_save.tar
docker load -i test_save.tar

Docker Copy :
docker cp filename container_id:/path_to_file/file
docker cp container_id:/path_to_file/file src_file/file

Find Serial Number by SNMPWALK

find snmp OID:

snmpwalk -l noAuthNoPriv -v 1 -c COMUNICATION_STRING -On IP_ADDRESS | grep SERIALNUM

snmpwalk -l noAuthNoPriv -v3 IP_ADDRESS -u user -On

find serial by OID:

snmpwalk -l noAuthNoPriv -v 1 -c COMUNICATION_STRING -On IP_ADDRESS .1.3.6.1.2.1.47.1.1.1.1.11.1

snmpwalk -l noAuthNoPriv -v3 IP_ADDRESS -u user -On .1.3.6.1.2.1.47.1.1.1.1.11.67108867

find by network range:

for i in {1..20}; do echo ip = 192.168.1.$i Serial: ; snmpwalk -l noAuthNoPriv -v 1 -c COMUNICATION_STRING -On 192.168.1.$i .1.3.6.1.2.1.47.1.1.1.1.11.1  | awk '{print $4}'; done
