I have setup a SFTP server on my Personal PC. I have started the service with the following configuration:

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

The strategy used for options in the default sshd_config shipped with


OpenSSH is to specify options with their default value where


possible, but leave them commented.  Uncommented options override the


default value.


#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::


#HostKey PROGRAMDATA/ssh/ssh_host_rsa_key
#HostKey PROGRAMDATA/ssh/ssh_host_dsa_key
#HostKey PROGRAMDATA/ssh/ssh_host_ecdsa_key
#HostKey PROGRAMDATA/ssh/ssh_host_ed25519_key


Ciphers and keying


#RekeyLimit default none


Logging


#SyslogFacility AUTH
#LogLevel INFO


Authentication:


#LoginGraceTime 2m
#PermitRootLogin prohibit-password
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10


#PubkeyAuthentication yes


The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2


but this is overridden so installations will only check .ssh/authorized_keys


AuthorizedKeysFile  .ssh/authorized_keys


#AuthorizedPrincipalsFile none


For this to work you will also need host keys in %programData%/ssh/ssh_known_hosts


#HostbasedAuthentication no


Change to yes if you don't trust ~/.ssh/known_hosts for


HostbasedAuthentication


#IgnoreUserKnownHosts no


Don't read the user's ~/.rhosts and ~/.shosts files


#IgnoreRhosts yes


To disable tunneled clear text passwords, change to no here!


#PasswordAuthentication yes
#PermitEmptyPasswords no


GSSAPI options


#GSSAPIAuthentication no


#AllowAgentForwarding yes
#AllowTcpForwarding yes
#GatewayPorts no
#PermitTTY yes
#PrintMotd yes
#PrintLastLog yes
#TCPKeepAlive yes
#UseLogin no
#PermitUserEnvironment no
#ClientAliveInterval 0
#ClientAliveCountMax 3
#UseDNS no
#PidFile /var/run/sshd.pid
#MaxStartups 10:30:100
#PermitTunnel no
ChrootDirectory "H:\FTP_Folder"
#VersionAddendum none


no default banner path


#Banner none


override default of no subsystems


Subsystem   sftp    sftp-server.exe


Example of overriding settings on a per-user basis


#Match User anoncvs


AllowTcpForwarding no


PermitTTY no


ForceCommand cvs server


Match Group administrators
       AuthorizedKeysFile PROGRAMDATA/ssh/administrators_authorized_keys

I have just changed the default directory and started the service.

I have created a local "ftp-user" on my Personal PC and given the directory access to the FTP server as follows:

FTP Folder permissions

Now, I have also checked firewall advanced settings and found that openssh is already enabled:

Windows Firewall settings

Port 22 is opened in TCP for Public, private and Domain.

Also, I have configured the router to set Port Forwarding as follows:

Router settings

At this juncture, my private IP defined by LAN is 192.168.1.4. I am able to connect through localhost and private IP address without any problem. But, if I use my cellular connection (public) and use the public IP of my PC to connect, I am unable to do so. It just timeouts.

I am unable to find any logs in ssh connection. I tried changing sshd_config Logging to Verbose but no files got generated in C:/programdata/ssh/logs.

I am trying to connect from my Phone sftp client (running on its own cellular data) to connect to my PC running on my Wifi.

Peeps. Help me a bit here!!
