Environment:192.168.2.10192.168.2.11Implementation: 2.10 SSH without password login to 2.11In 2.10 ssh to 2.11 machines, a password is required, which makes it inconvenient for some scripts to work because of the need for a password, which requires manual intervention. The previous method is to copy Authorized_keys inside (remember, before), recently found a command ssh

I am a student party, the school's network restrictions on the comparison of strict, this can not be on that can not log on. Windows 3389 is not available and Linux 22 ports are not available.
All will need to modify the port to implement.
First, find a way to connect to your Linux server.(Mobile hot can OH)
First modify the configuration file
Vi/etc/
A slow connection occurs when using an SSH client to connect to another Linux server on Linux. But to change a client to even find the speed is normal. Assume that the SSH client appears as a problem.So using ssh-v IP debugging, sure enough to find the problem. The output is

Everyone knows. Linux is case sensitive. Windows. But the same port number parameter. The use of SCP and SSH commands is different.
In the SCP command. Uppercase is required. As follows:
[Root @ localhost data] # SCP-P 28 fina_info20120904.zip root@58.213.14.170:/home/huanliu/Data
In the SSH command, it is in lower
A linux iptables not only can be used to do the firewall can also be used to do port forwarding: example: Forwarding the 8080 port of the machine to another host, host ip:192.168.1.12, target host IP and port: 192.168.1.13 : 8088,
In Centos 6.9, the default port of SSH is modified.
There are a lot of blogs about modifying the default SSH port of Centos6.5 in Linux. I won't bother here, but in the face of Centos 6.9, there will be a big pitfall;
After modifying iptables, run the following command;
#
[wlan0-ip] -p tcp -j dnat --to [client-ip]It is worth mentioning that iptables essentially simply filters and processes data, so it is accurate to allow wlan1 traffic to be forwarded to Wlan0,In fact, if the default policy is used, forward is allowed without additional settings.Example 3. act as a transparent proxyDifferent people have different requirements for agents, the most common is the HTTP proxy, generally provides the address and port number
How does one access the Linux server after NAT through SSH reverse tunnel? (1)
Suppose you are running a Linux server at home, which is behind the NAT router or restricted firewall. Now, you can connect to the home server through SSH when you are not at home. How do you do this? S

In fact, most Linux VPN modules (ppp) basically adopt route forwarding. If you want to use Linux to implement the most basic routing (switch) function, you must enable the kernel forwarding service. 1. enable the Linux kernel to forward echo quot; 1 quot; gt;/proc/sys/net
complicated than that.2. The GRE tunnel has no state control, and one end of the tunnel may be closed while the other end is still open. The solution to this problem is to open keepalive packets at both ends of the tunnel. It allows the end of the tunnel to periodically send keepalive data to the other end, confirming that the port remains open. If one end of the tunnel does not receive keepalive data on time, the tunnel

Question: I think SSH has two versions (SSH1 and SSH2 ). What is the difference between the two? Also, how can I check the SSH protocol version on Linux? Secure Shell (SSH) uses an encrypted secure communication channel to remotely log on or execute commands. SSH is designed
communicating.When the switch establishes the complete MAC address table, the data frame is forwarded by looking up the MAC address table to get the corresponding port, thus sending the data frame through a specific port. However, for broadcast data that enters from a port and no address entry is found in the Address table, the switch forwards the data frame fro
