Cannot ping VM on 3Engines Cloud[🔗](#cannot-ping-vm-on-brand-name "Permalink to this headline")
=================================================================================================

If you have problems with access to your VM - ping is not responding. Try the following:

install the packages **net-tools** (to have the **ifconfig** command) and **arping**:

in CentOS:

```
sudo yum install net-tools arping

```

in Ubuntu:

```
sudo apt install net-tools arping

```

check the name of the interface connected to private network:

```
ifconfig

```

based on the response, find the number of the interface of 192.168.x.x (eth<number> or ens<number>)

after that invoke the following commands:

in CentOS:

```
sudo arping -U -c 2 -I eth<number> $(ip -4 a show dev eth<number> | sed -n 's/.*inet \([0-9\.]\+\).*/\1/p')

```

in Ubuntu:

```
sudo arping -U -c 2 -I ens<number> $(ip -4 a show dev ens<number> | sed -n 's/.*inet \([0-9\.]\+\).*/\1/p')

```

Next ping your external ip address and check if it helped.
