我想重命名我的网络上的一个设备,因为我有来自同一个mfg的几个设备。例如,华硕无线路由器与华硕主板(通过以太网连接)显示相同的mfg名称,如下所示:
Nmap scan report for 192.168.1.110
Host is up (0.0013s latency).
MAC Address: (mac) (Asustek Computer)
Nmap scan report for 192.168.1.105
Host is up (-0.100s latency).
MAC Address: (different mac) (Asustek Computer)
计算机正在运行Ub
我最近买了一个Arduino以太网屏,但无法让它工作。
我尝试使用示例的代码,但它不起作用。我甚至尝试过在不使用DHCP的情况下获取静态IP,但总是出现相同的问题。
我使用了下面的代码:
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = { 0x90, 0xA
我试图在ESP32上使用Micropython完成一个简单的get请求。不幸的是,我一直得到OSError: -202。
这就是我到目前为止所拥有的:
wlan.py
import network
wlan = network.WLAN(network.STA_IF) # create station interface
wlan.active(True) # activate the interface
wlan.connect('Schmittli', 'the key') # connect to an AP
wlan.ifconfig()
所以我有一个非常基本的脚本:
#region Get Hostname IP
IPAddress[] dnsRecords = Dns.GetHostAddresses(hostname);
string ipHostname = dnsRecords[0].ToString();
if (ipHostname.Length == 0) {
responseCode = imapLoginResponse.Failed;
return false;
}
#endregion
#region Try make a request to the Host, Port
try {
我尝试运行了几个nmap命令,但无法获得返回主机名的结果。我的结果如下:
Nmap scan report for 10.2.16.253
Host is up (0.0025s latency).
All 1000 scanned ports on 10.2.16.253 are in ignored states.
Not shown: 1000 filtered tcp ports (no-response)
MAC Address: D8:D0:90:2F:6C:34 (Dell)
我尝试过的Nmap命令:
sudo nmap 10.2.16.0/24 -Pn
sudo nmap 10
当我在我的bash shell中输入arp -a时,我得到如下输出:
