Ubuntu ssh Android phone

The relationship between Android and Linux can refer to this blog post:

Android phones can install tools such as Terminal, SSHDroid, etc.

To use ssh to log in to an android phone, you need to pay attention to the configuration port:

# Package generated configuration file
# See the sshd_config(5) manpage for details

# What ports, IPs and protocols we listen for
Port 1234
# Use these options to restrict which interfaces/protocols sshd will bind to
# ListenAddress ::
# ListenAddress 0.0.0.0
# ListenAddress 0.0.0.0

Protocol 2
# HostKeys for protocol version 2
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key
HostKey /etc/ssh/ssh_host_ecdsa_key
HostKey /etc/ssh/ssh_host_ed25519_key
# Privilege Separation is turned on for security
UsePrivilegeSeparation yes

# Lifetime and size of ephemeral version 1 server key
KeyRegenerationInterval 3600
ServerKeyBits 1024

# Logging
SyslogFacility AUTH
LogLevel INFO

# Authentication:
LoginGraceTime 120
PermitRootLogin without-password
StrictModes yes

RSAAuthentication yes
PubkeyAuthentication yes
# AuthorizedKeysFile	%h/.ssh/authorized_keys

# Don't read the user's ~/.rhosts and ~/.shosts files
IgnoreRhosts yes
# For this to work you will also need host keys in/etc/ssh_known_hosts
RhostsRSAAuthentication no
# similar for protocol version 2
HostbasedAuthentication no
# Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication
# IgnoreUserKnownHosts yes

# To enable empty passwords, change to yes(NOT RECOMMENDED)
PermitEmptyPasswords no

# Change to yes to enable challenge-response passwords(beware issues with
# some PAM modules and threads)
ChallengeResponseAuthentication no

# Change to no to disable tunnelled clear text passwords
# PasswordAuthentication yes

# Kerberos options
# KerberosAuthentication no
# KerberosGetAFSToken no
# KerberosOrLocalPasswd yes
# KerberosTicketCleanup yes

# GSSAPI options
# GSSAPIAuthentication no
# GSSAPICleanupCredentials yes

X11Forwarding yes
X11DisplayOffset 10
PrintMotd no
PrintLastLog yes
TCPKeepAlive yes
# UseLogin no

# MaxStartups 10:30:60
# Banner /etc/issue.net

# Allow client to pass locale environment variables
AcceptEnv LANG LC_*

Subsystem sftp /usr/lib/openssh/sftp-server

# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of"PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
UsePAM yes

• • • • After the configuration is complete, restart sudo /etc/init.d/ssh restart

Then you can use ssh to log in to the phone:
