偷懒,直接CP了

New features:
* VPCs now checks for duplicate addresses when assigning IPv4 addresses
* DNS is now supported
* Much more extensive help
* tracert has been simplified to just trace, and allows for protocols other than UDP (TCP & ICMP)
* Some commands have been replaced with more logical syntax, but usually the old syntax still works:

arp     is now show arp
dhcp    is now ip dhcp
ver     is now show version
history is now show history

New commands:

help (same as ?)
rlogin (telnet to a port on a host)
sleep (useful in scripts)
set dump (great for seeing protocols at work)

Modified commands:
arp  (now show arp - with more options)
dhcp (now ip dhcp - with more options)
show (many more options)
clear (more options)
ip (more options including DNS)
set (more options)
trace (formally tracert, more options)

Bug fixes:
The source port for pings to TCP & UDP ports is now random, allowing it to work through firewalls
DHCP now sets option 12 (Host Name) correctly in the DHCP Discover
The echo command no longer leaves blank lines between output


Details:

* Many more options for the show command:

show [arp [|all]|dump|echo|history|ip [|all]|ipv6 [|all]]
    arp [|all]   Show arp table for VPC or all VPCs
    dump [|all]  Show dump flags for VPC or all VPCs
    echo                Show the status of the echo flag (see set echo)
    history             List the command history
    ip [|all]    Show IPv4 details for VPC or all VPCs
                        Shows VPC Name, IP address, mask, gateway, DNS, MAC, 
                        lport, rhost:rport and MTU
    ipv6 [|all]  Show IPv6 details for VPC or all VPCs
                        Shows VPC Name, IPv6 addresses/mask, gateway, MAC,
                        lport, rhost:rport and MTU
    version             Show the version information

  Notes: if and are missing, arp/dump/ip/ipv6 will display
         the current VPC.
         
* In particular, the new show ip and show ipv6 commands are really useful

show ip [|all]
  Show IPv4 details for VPC (default this VPC) or all VPCs, including
  VPC Name, IP address, mask, gateway, DNS, MAC, lport, rhost:rport and MTU.

* A new set dump command, great for debugging protocols:

set dump [detail|mac|raw|all|off]
  Set the packet dump flag for this VPC
    detail  print protocol
    mac     print ether address
    raw     print the first 40 bytes
    all     all the packets including incoming
            must use [detail|mac|raw] as well as 'all'
    off     clear all the flags

* New options for dhcp, including a decode option to display the contents of the dhcp packets:

ip dhcp [-options]
  Attempt to obtain IPv4 address, mask, gateway and DNS via DHCP
  options:
    -d         Show DHCP packet decode
    -r         Renew DHCP lease
    -x         Release DHCP lease

* More flexible ip address settings, and new settings for DNS and dhcp:

ip [arguments]
  Configure the current VPC's IP settings
  arguments:
   
[/] []
   
[] [/]
                   Set the VPC's ip, default gateway ip and network mask
                   Default IPv4 mask is /24, IPv6 is /64. In the ether mode, 
                   the ip of the tapx is the maximum host ID of the subnet. 
                   ip 10.1.1.70 /26 10.1.1.65 set the VPC's ip to 10.1.1.70, 
                   the gateway to 10.1.1.65, the netmask to 255.255.255.192, 
                   the tapx ip to 10.1.1.126 in the ether mode.
                    may be written as /26, 26 or 255.255.255.192
    auto           Attempt to obtain IPv6 address, mask and gateway using SLAAC
    dhcp -[d|r|x]  Attempt to obtain IPv4 address, mask, gateway, DNS via DHCP
          -d         Show DHCP packet decode
          -r         Renew DHCP lease
          -x         Release DHCP lease
    dns       Set DNS server , delete if is '0'
    mtu    Set IPv4 MTU to , at least 576.

* New rlogin command allows you to telnet to router console ports directly from VPCs

rlogin []
  Telnet to at (def 127.0.0.1) relative to HOST PC. 
  To attach to the console of a virtual router running on port 2000 of this
  host PC, use rlogin 2000
  To telnet to the port 2004 of a remote host 10.1.1.1, use
  rlogin 10.1.1.1 2004


* New sleep command, useful in the execution of scripts

sleep [] []
  Print and pause execution of script for .
  If =0 or missing, pause until a key is pressed. 
  See load


* New command trace (replaces tracert) allows tracing a path to a host using UDP/TCP or ICMP

trace [-options]
  Print the path take to network . can be an ip address or name.
    options:
      -P  Use IP in trace packets
                     1 - icmp, 17 - udp (default), 6 - tcp  
      -m       maximum TTL, default 8
               Same as -m option, compatible with the old version
