If centos5.5 is installed on VMware, secureCRT cannot be used for remote login. During installation, select the network connection mode as bridging, and disable linux's selinux kernel protection mechanism. At first, I thought it was my own setup problem, so services iptables stop disabled iptables. I tried the ping command and found that centos5.5 can ping the IP address of my XP system, and the IP address of the centos Nic can also be pinged. In XP, I tried telnet 192.168.0.49 22 and the result could not be connected.
At this time, a colleague of mine asked me about the centos IP address, and then tested the connection. Then he connected it. At this time, the problem is clear. It's not a problem with the centos virtual machine, it's a problem with my own XP system. But I still don't know where the problem is. Finally, my other colleague suddenly said that he had encountered similar problems before and finally found a solution. It was just too long to forget the solution. Then he immediately Baidu, A few minutes later, I found the correct solution to the problem. It turns out to be a local Nic configuration problem. The solution is as follows:
Right-click the local connection, select [properties], and click the [configuration] button on the [general] tab ()
Select [hardware checksum] In the Properties window of the [advanced] tab and disable it in the value option on the right.
Now it's okay. Let's take a look at the comparison between the connection interface of putty before and after modification.
Before modification ()
After modification, the connection can be established normally.
