summarized the solutions when the ssh connection fails for your reference. If you have any new ideas, you can discuss them together ~ There are no special instructions for the following tests: Use a common account to log on to www.2cto.com. I. ssh IP_A or ssh root @ IP_A both show Permission denied (publickey, gssapi-with-mic ). idea: Check whether the SSH version above IP_A is correct.

SSH or SCP is often used to connect to a bunch of remote hosts, which are also Linux Hosts. The speed of creating SSH connections is particularly slow, but the operation speed is normal after the connection is established, it seems that this is not the network reason. The solution is to view the debugging information through the-V parameter of SSH: Use SSH-V to view the detailed connection establishment process. I immediately tried it on a host that was slow to establish the connection and foun

Today, we finally stabilized the two-way audio communication between our mobile phone and the single-chip microcomputer, and took the first step of success. It can stably transmit a large data segment to each other, and both ends can fully identify the data. Last week, the mobile phone sent data to the MCU through audio. However, there is a problem that the mobile phone receives data from the microcontroller through mic. The main problem is that

Input Method is an essential tool for our work. Like Windows XP, in Vista, the input method is sometimes not very useful. In some cases, we will find that five inputs cannot be used normally in Windows Vista, pinyin and pinyin. Especially when running in IE browser. This is generally due to the role of the Internet security mode. The Internet security mode depends on the role of UAC, uipi, And Mic, therefore, it may be considered that the security

technology (802.1x) is an enhanced network security solution for wireless LAN. When the STA of the wireless workstation is associated with the AP of the wireless access point, whether the AP service can be used depends on the 802.1x authentication result. If the authentication succeeds, the AP opens the logical port for the STA. Otherwise, the user is not allowed to access the Internet. 802.1X requires the wireless workstation to install 802.1x client software. The wireless access point must be

(audio control)Volume Adjustment Process: The default value is interface 0, which sends the set cur command and the volume value. After the volume is changed, the set interface will be sent to interface 2 from interface 0, and then the audio data (PCM wave file) will be sent to interface 2 ), finally, send the set interface from interface 2 to interface 1.2. Interfaces 1 and 2: audio stream output (speak). Use endpoint 1, class 1 (audio), and subclass 2 (audio streaming ), the former balternate
