From the search results this is likely a network/routing/network settings

problem on your side and not specific to CentOS at all.

The TCP connection is being built successfully. We can know this by the fact that it has progressed to sending an application-layer PDU. If it were a routing issue, it would have failed to build a TCP connection (the SYN-ACK would have failed to return).

However, it is closed very soon after, during key exchange, so I would suggest you check your /etc/hosts.allow and /etc/hosts.deny. Check the contents of /etc/ssh/, in particular, is there anything in /etc/ssh/sshd_config that could be a problem?

Was this a clean reinstall, or an upgrade over an existing system?

Most importantly, is there anything in the server logs?

You mentioned "idc", what is that?

Your issues with nginx,php,mysql etc, are probably separate.

ssh is default 22 port

The system perfomance good a few time.but it is always happen a problem only need hardware reboot to solve.the server is on idc.so i can not see the local screen information.

the appearance is: 1.it can not use ssh to connect,it show server is down or rebooting 2.ping is ok 3.http can show nginx's information(nginx/0.8.46),but can not load right page,and it show 403 forbiden page

i use another server use ssh -vv xxx.xxx.xxx.xxx,and the responce is:

SSH2_MSG_KEXINIT sent

close

sshd hangs after SSH2_MSG_KEXINIT sent

i do not know what happen,please give me a good answer
