使用Xshell連接虛機安裝的vyOS

本文主要講解：使用虛機(Vitual Box)安裝的vyOS，如何使用Xshell來通過ssh方式連接。

首先咱們安裝vyOS

1.安裝vyOS

先用Vitual Box安裝vyOS鏡像。
接下來的操作其實官網教程講的很清楚了，基本就是一路默認往下點就可以。

主要就是執行這條語句install image

vyos@vyos:~$ install image
Welcome to the VyOS install program.  This script
will walk you through the process of installing the
VyOS image to a local hard drive.
Would you like to continue? (Yes/No) [Yes]: Yes
Probing drives: OK
Looking for pre-existing RAID groups...none found.
The VyOS image will require a minimum 2000MB root.
Would you like me to try to partition a drive automatically
or would you rather partition it manually with parted?  If
you have already setup your partitions, you may skip this step

Partition (Auto/Parted/Skip) [Auto]:

I found the following drives on your system:
 sda    4294MB

Install the image on? [sda]:

This will destroy all data on /dev/sda.
Continue? (Yes/No) [No]: Yes

How big of a root partition should I create? (2000MB - 4294MB) [4294]MB:

Creating filesystem on /dev/sda1: OK
Done!
Mounting /dev/sda1...
What would you like to name this image? [1.2.0-rolling+201809210337]:
OK.  This image will be named: 1.2.0-rolling+201809210337
Copying squashfs image...
Copying kernel and initrd images...
Done!
I found the following configuration files:
    /opt/vyatta/etc/config.boot.default
Which one should I copy to sda? [/opt/vyatta/etc/config.boot.default]:

Copying /opt/vyatta/etc/config.boot.default to sda.
Enter password for administrator account
Enter password for user 'vyos':
Retype password for user 'vyos':
I need to install the GRUB boot loader.
I found the following drives on your system:
 sda    4294MB

Which drive should GRUB modify the boot partition on? [sda]:

Setting up grub: OK
Done!
vyos@vyos:~$

最後重啓系統：

vyos@vyos:~$ reboot
Proceed with reboot? (Yes/No) [No] Yes

2.配置vyOS可通過SSH連接

2.1 進入配置模式

vyos@vyos$ configure
vyos@vyos#

2.2 配置網絡接口

vyos@vyos# set interfaces ethernet eth0 address dhcp
vyos@vyos# set interfaces ethernet eth0 description 'OUTSIDE'

2.3 啓用ssh

vyos@vyos# set service ssh port '22'

2.4 保存改動

vyos@vyos# commit
vyos@vyos# save

3. 配置Xshell連接

3.1 獲取連接ip

接着2.4的操作：

vyos@vyos# exit
vyos@vyos$ sudo ifconfig 
eth0      Link encap:Ethernet  HWaddr 08:00:27:40:ac:ef  
          inet addr:你需要複製的地址  Bcast:XXX.XXX.XXX.XXX  Mask:255.255.255.0
          inet6 addr: fe80::a00:27ff:fe40:acef/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:2425 errors:0 dropped:0 overruns:0 frame:0
          TX packets:185 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:237660 (232.0 KiB)  TX bytes:19908 (19.4 KiB)

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:30910 errors:0 dropped:0 overruns:0 frame:0
          TX packets:30910 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:1865376 (1.7 MiB)  TX bytes:1865376 (1.7 MiB)

你如果直接把上面的ip地址複製進入Xshell連接配置的主機(H)欄，大概率是連不上虛機中的vyOS的，
在進行接下來的操作之前，我們還需要修改虛機的橋接模式

3.2 修改虛機橋接模式

選擇vyOS虛機，右鍵 > 設置 > 網絡 > 網卡1 > 連接方式 > 選擇橋接網卡。

執行完上面操作後，咱們再次獲取連接ip，操作同3.1。

3.3 再次獲取連接ip

將獲取到的ip填入到Xshell連接配置的主機(H)欄。賬號密碼都是安裝vyOS時候設置的。即vyos。

這樣一來，就OK了！
