linux-ssh连接不上远程Linux服务器——CSDN问答 … 2017-8-29 海外服务器能ping通但是SSH无法连接问题 - ic翼 2020-4-25 · ping 走的是 ICMP,能ping通说明ICMP没有被阻断。TCP阻断 SSH 走的是 TCP,IP 能 ping 通但 SSH 连接不上是因为 ICMP 报文是放行的,但是 TCP 报文都被拦截了,所以在你检测 IP 时,表面上 IP 正常能 ping 通,但是端口 TCP 已经被墙。 Linux 可以SSH,但ping不通-Tony-51CTO博客 2017-8-30 · 可以ping通! ©著作权归作者所有:来自51CTO博客作者tonyyyt的原创作品,如需转载,请注明出处,否则将追究法律责任 Linux Ping Linux

If the original poster is able to SSH to the device from his laptop then this demonstrates that SSH is enabled and seems correctly configured (which rules out one of the most common problems). If other devices are able to ping then it seems to demonstrate IP connectivity and correct routing (which rules out another of the common problems).

Just leave it as SSH. SSH is a secure, encrypted communications protocol designed to ensure your password and data are maximally protected. Raw connections might be used for developers to connect a TCP/IP socket for testing (e.g., when developing a network application that listens on a TCP/IP port). The proxy is the "endpoint" for our ping packets, i.e. the computer that we send the ping packets to. The client is the computer we're trying to surf the net from, and the destination is the computer we would normally be trying to access over TCP (such as a web site or an ssh server somewhere). $ sudo rm /etc/ssh/ssh_host_* && sudo dpkg-reconfigure openssh-server. There must be some way to screw up the Raspbian installation that produces this particular problem. And all this is assuming you already had the presence of mind to enable ssh in raspi-config. That of course is a prerequisite. Conclusion Managing PING through iptables. Allow/deny ping on Linux server. PING – Packet InterNet Gopher, is a computer network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the total round-trip time for messages sent from the originating host to a destination computer and back. $ ssh -t [email protected] sudo touch /etc/banner.txt. Note that we have used ‘-t‘ option with SSH, which allows pseudo-terminal allocation. sudo command requires interactive terminal hence this option is necessary. Execute script. Remote execution is not only limited to the commands; we can even execute script over SSH.
