Troubleshooting sshfs mount failures

Write code to run on Linux, but familiar IDE (such as VS code) on your own computer, you can use sshfs to mount the directory on linux locally, and then just open it with VScode, you can use the following command:

sshfs -odebug,sshfs_debug,loglevel=debug  -o rw,allow_other,uid=1190,gid=1190,reconnect,ServerAliveInterval=15,ServerAliveCountMax=3,IdentityFile=/Users/hailiang8/.privateKey [email protected]:/data1/workspace/mount/ffmpeg /Users/harlanc/workspace_ffmpeg

But today I encountered a problem, in other CentOS machine no problem, but to 192.168.23.2 this machine can not connect, reported the following error:

SSHFS version 2.5

remote host has disconnected

The server is actively disconnecting, check the server's ssh service:

[root@harlanc]# netstat -nltp | grep sshd
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      1085/sshd
tcp6       0      0 :::22                   :::*                    LISTEN      1085/sshd

Looking at the specifics of the ssh process:

[root@ harlanc]# ps -ef | grep 1085
root 1085 1 0 15:39 ?        00:00:00 /usr/local/sbin/sshd -D

[root@ harlanc]# rpm -qf /usr/local/sbin/sshd
***openssh-6.7.x86_64 //here **** is the name of our company

It turns out that we were using our company's own ssh service.

And in the CentOS machine can be connected to the use of openssh this open source ssh service, to replace our service is not very realistic, you can change the openssh service to a port to start up:

 vim /etc/ssh/sshd_config

locate

 Port 22

replace with

 Port 23

Get openssh up and running:

[root@ harlanc]# systemctl start sshd

Now both services are up:

[root@ harlanc]#  netstat -nltp | grep sshd
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      1085/sshd
tcp        0      0 0.0.0.0:23              0.0.0.0:*               LISTEN      316299/sshd
tcp6       0      0 :::22                   :::*                    LISTEN      1085/sshd
tcp6       0      0 :::23                   :::*                    LISTEN      316299/sshd

Specify the port when mounting with sshfs:

 sshfs -p 23 -odebug,sshfs_debug,loglevel=debug  -o rw,allow_other,uid=1190,gid=1190,reconnect,ServerAliveInterval=15,ServerAliveCountMax=3,IdentityFile=/Users/hailiang8/.privateKey [email protected]:/data1/workspace/mount/ffmpeg /Users/harlanc/workspace_ffmpeg

It finally mounted at last.
