Accessing the SoC via the Management Port or the USB Port

Use this information to enable remote SSH access via the management port or the USB port for remote management.

Before you begin

Make sure that you have:

Installed a Napatech IPU in a server.
- F207xX IPUs: See Install in a Server in DN-1374.
- F307xX IPUs: See Install in a Server in DN-1409.
Connected a UART console cable cable.
- F207xX IPUs: See Connecting a UART console cable in DN-1374.
- F307xX IPUs: See Connecting a UART console cable in DN-1409.
Access to the SoC using the UART interface on an IPU. See Accessing the SoC via the UART Interface.
Connected a network cable to the management port or to the USB port on the IPU. If you are using the USB port, ensure that you have connected a USB-to-RJ45 adapter to it.

About this task

This procedure shows you how to configure the SoC via the UART interface on the IPU for enabling SSH access using the management port or the USB port.

Procedure

On the serial console, log in to the IPU if a login prompt is displayed.
For example:
```
…
…
Type [C-a] [C-h] to see available commands
Terminal ready

localhost login: root
Password:
```
You can log in to the IPU using the following default credentials.
- User name: root
- Password: ipuadm123
Check the configuration file for the network interface.
For example:
```
vim /etc/systemd/network/i210-wired.network
```
It is configured for DHCP by default. Edit the file with the desired network configuration.
```
[Match]
Name=enp1s0
[Network]
DHCP=yes
```
For setting a static IP address, see the following configuration example.
```
[Match]
Name=enp1s0
[Network]
DHCP=no
DNS=10.20.22.1
[Address]
Address=10.20.22.222/24
[Route]
Gateway=10.20.22.1
```
Restart systemd-networkd if the network configuration is changed.
```
systemctl restart systemd-networkd
```

Check the assigned IP address.

ip a

An output example:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:0d:e9:f1:08:27 brd ff:ff:ff:ff:ff:ff
    inet 10.10.8.178/22 metric 1024 brd 10.10.11.255 scope global dynamic enp1s0

    inet6 fe80::20d:e9ff:fef1:827/64 scope link
       valid_lft forever preferred_lft forever

Log in via SSH.
You can log in from a remote SSH session using an SSH client, provided you have network connectivity. Connect to the IPU remotely using SSH.
```
ssh root@<IP>
```
where IP is the actual IP address assigned to the IPU.
