SSH

Getting Started

Basic SSH Connection

Establishing remote connections to servers

Connect to Remote Host with Default Settings

Connects to a remote host using SSH, with interactive password authentication. The host key is verified and stored in ~/.ssh/known_hosts

Code

ssh hostname

Execution

The authenticity of host 'hostname (192.168.1.100)' can't be established.
ECDSA key fingerprint is SHA256:abc123xyz...
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'hostname' (ECDSA) to the list of known hosts.
Last login: Wed Feb 28 10:30:42 2026 from 192.168.1.50
user@hostname:~$

First connection will prompt for host key verification
Uses default SSH port 22
Requires password authentication if no keys configured

Connect with Specific Username

Connect using a specific username different from local user. Format is [user@]hostname

Code

ssh user@hostname

Execution

user@hostname's password:
Last login: Wed Feb 28 10:35:15 2026 from 192.168.1.50
user@hostname:~$

If username not specified, uses current local username
Can also specify as user@domain.com or user@ip.address

Connect to Non-Standard Port

SSH server might run on ports other than 22. Use -p flag to specify alternative port

Code

ssh -p 2222 user@hostname

Execution

user@hostname's password:
Last login: Wed Feb 28 09:15:22 2026 from 192.168.1.50
user@hostname:~$

Port must be specified before hostname
Common alternative port is 2222
Can also configure in ~/.ssh/config

Authentication Methods

Public Key Authentication

Using SSH keys for passwordless authentication

Generate ED25519 SSH Key Pair

Create a new ED25519 key pair. This modern algorithm is preferred over RSA for better security

Code

ssh-keygen -t ed25519 -C "user@example.com"

Execution

Generating public/private ed25519 key pair.
Enter file in which to save the key (/home/user/.ssh/id_ed25519):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/user/.ssh/id_ed25519
Your public key has been saved in /home/user/.ssh/id_ed25519.pub
The key fingerprint is: SHA256:xyz123abc... user@example.com

Ed25519 is the recommended key type (fast, secure, compact)
Use -C to add a comment identifying the key
Protect private key with strong passphrase

Add Public Key to Remote Host

Copy public key to remote host's authorized_keys. Enables passwordless login

Code

ssh-copy-id -i ~/.ssh/id_ed25519.pub user@hostname

Execution

/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/user/.ssh/id_ed25519.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s)...
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed - if you want to re-run this setup...
Number of key(s) added: 1

Requires initial password authentication
Appends to ~/.ssh/authorized_keys on remote

Connect Using Specific Key

Explicitly specify private key for authentication. Useful when multiple keys exist

Code

ssh -i ~/.ssh/id_ed25519 user@hostname

Execution

Last login: Wed Feb 28 11:45:30 2026 from 192.168.1.50
user@hostname:~$

SSH tries default keys if -i not specified
Default keys: ~/.ssh/id_rsa, ~/.ssh/id_ecdsa, ~/.ssh/id_ed25519

Password Authentication

Interactive password-based login

Force Password Authentication

Disable public key auth and force password authentication. Useful for testing or shared accounts

Code

ssh -o PubkeyAuthentication=no user@hostname

Execution

user@hostname's password:
Last login: Wed Feb 28 10:20:15 2026
user@hostname:~$

Password transmitted securely through SSH tunnel
Server must have PasswordAuthentication enabled

Non-Interactive Password (Using sshpass)

Pass password non-interactively using sshpass utility. Not recommended for security

Code

sshpass -p 'password' ssh user@hostname

Execution

Last login: Wed Feb 28 11:25:10 2026
user@hostname:~$

sshpass must be installed separately
Security risk: password visible in process list and history
Use SSH keys instead for automation

SSH Agent & Key Forwarding

Use ssh-agent to manage keys across multiple hops

Start SSH Agent in Current Shell

Initialize SSH agent in current shell session. Required before adding keys

Code

eval "$(ssh-agent -s)"

Execution

Agent pid 12345

Agent runs as background process
PID stored in SSH_AUTH_SOCK environment variable

Add Private Key to Agent

Add private key to SSH agent. Benefits: Enter passphrase once, agent handles auth on multiple connections

Code

ssh-add ~/.ssh/id_ed25519

Execution

Enter passphrase for /home/user/.ssh/id_ed25519:
Identity added: /home/user/.ssh/id_ed25519 (user@example.com)

Prompted for passphrase only once
Key unlocked in agent memory until timeout or logout

Enable Agent Forwarding to Remote Host

Forward SSH agent connection to remote host. Allows using local keys from remote for further hops (jump hosts)

Code

ssh -A user@hostname

Execution

Last login: Wed Feb 28 12:00:00 2026
user@hostname:~$ ssh-add -l
256 SHA256:xyz... user@example.com (ED25519)

Requires ForwardAgent yes in ssh_config (or use -A flag)
Security: Only enable for trusted hosts
Useful for jump host scenarios

Port Forwarding & Tunneling

Local Port Forwarding

Forward local port to remote service

Forward Local Port to Remote Service

Forward localhost:3306 through SSH tunnel to remote database server. Local connections to 3306 proxy through SSH

Code

ssh -L 3306:localhost:3306 user@database-host

Execution

Last login: Wed Feb 28 08:30:00 2026
user@database-host:~$

Format: -L [bind_address:]local_port:remote_host:remote_port
Connection stays open for tunnel to function
Useful for accessing internal services through SSH

Forward with Non-Standard Local Port

Forward local port 13306 to remote database server db.internal:3306. Avoids port conflicts with local services

Code

ssh -L 13306:db.internal:3306 user@bastion-host

Execution

user@bastion-host:~$

Connect to localhost:13306 to access remote database
Allows multiple forwards on different local ports

Forward Multiple Ports

Forward multiple local ports to different remote services through single SSH connection

Code

ssh -L 3306:db:3306 -L 5432:db:5432 user@bastion-host

Execution

user@bastion-host:~$

Use multiple -L flags for each port forward
Efficient: only one SSH tunnel to bastion

Remote Port Forwarding

Forward remote port to local service

Expose Local Service to Remote Network

Forward remote port 8080 to local service on 8080. Remote server can access local service. Enables public access to private service

Code

ssh -R 8080:localhost:8080 user@public-server

Execution

user@public-server:~$

Format: -R [bind_address:]remote_port:local_host:local_port
Requires GatewayPorts yes on remote server for external access
Useful for exposing localhost dev server to internet

Bind to All Interfaces on Remote

Expose local service to all interfaces on remote host (not just localhost). Requires GatewayPorts enabled

Code

ssh -R '*':3000:localhost:3000 user@public-server

Execution

user@public-server:~$

Use '*' or empty bind_address for all interfaces
Security: Only do for development, not production

Dynamic Port Forwarding (SOCKS Proxy)

Create SOCKS proxy through SSH tunnel

Create SOCKS5 Proxy

Create SOCKS5 proxy on localhost:1080. All traffic through proxy routes through SSH tunnel to remote network

Code

ssh -D 1080 user@ssh-server

Execution

Last login: Wed Feb 28 09:15:00 2026
user@ssh-server:~$

Format: -D [bind_address:]local_port
Browser/application must support SOCKS5
Useful for accessing services on remote private network

Configure Browser to Use SOCKS Proxy

Route traffic through SOCKS proxy to access internal services as if on remote network

Code

# Firefox: Preferences > General > Network Settings > SOCKS Host
# localhost, port 1080, SOCKS v5

# Or use command-line tool
curl --socks5 localhost:1080 https://internal.company.com

Execution

<!DOCTYPE html>
<html>
<head><title>Internal Company Site</title></head>
<body>Welcome to internal site</body>
</html>

Many tools support SOCKS: curl, youtube-dl, etc.

Key Management

Creating and Managing Keys

Generate, manage, and secure SSH keys

Generate RSA Key for Legacy Systems

Create RSA key for systems that don't support Ed25519. Use 4096-bit for adequate security

Code

ssh-keygen -t rsa -b 4096 -C "legacy-key"

Execution

Generating public/private rsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Your identification has been saved in /home/user/.ssh/id_rsa
Your public key has been saved in /home/user/.ssh/id_rsa.pub

RSA requires larger key size (4096) compared to Ed25519 (256)
Slower but widely supported

List Keys Added to Agent

Display all keys currently loaded in SSH agent with their fingerprints

Code

ssh-add -l

Execution

256 SHA256:xyz... user@example.com (ED25519)
4096 SHA256:abc... legacy-key (RSA)

Shows key type, fingerprint, and comment
Returns exit code 1 if agent not running

Export Public Key from Private Key

Recover/regenerate public key from existing private key

Code

ssh-keygen -y -f ~/.ssh/id_ed25519 > ~/.ssh/id_ed25519.pub

Execution

ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJxyz... user@example.com

Useful if public key lost
Only works if you have the private key

Managing Authorized Keys

Control which keys can access your account

View Authorized Keys

Display all public keys that can authenticate as current user. One key per line

Code

cat ~/.ssh/authorized_keys

Execution

ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIO.../key1 user@host1
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIO.../key2 user@host2
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAAA... legacy-key

File location: ~/.ssh/authorized_keys
Permissions must be 600
Directory ~/.ssh must be 700

Remove Specific Key

Remove specific key by filtering it out. Revokes access for that key

Code

grep -v "key1" ~/.ssh/authorized_keys > /tmp/authorized_keys.tmp
mv /tmp/authorized_keys.tmp ~/.ssh/authorized_keys

Execution

(file updated)

Use tools like ssh-keyscan for managing multiple hosts

Set Command Restrictions on Key

Restrict key to only execute specific command. Useful for automation/backups with limited permissions

Code

echo 'command="/usr/local/bin/backup.sh" ssh-ed25519 AAAAC3...' >> ~/.ssh/authorized_keys

Execution

(user logging in with this key will only run backup.sh)

Key can only run the specified command
Useful for automated backups, deployments

Configuration & Advanced Setup

SSH Config File

Configure hosts, defaults, and connection settings in ~/.ssh/config

Basic Host Configuration

Define host aliases and connection parameters in ~/.ssh/config. Simplifies repeated connections

Code

cat ~/.ssh/config

Execution

Host myserver
  HostName server.example.com
  User admin
  Port 2222
  IdentityFile ~/.ssh/id_ed25519

Host *.internal
  User intern_user
  ProxyJump bastion

Format: Host pattern followed by configuration options
* and ? wildcards supported in Host patterns
Configuration applied in order, first match wins

Connect Using Host Alias

Use hostname alias instead of full connection details. All config parameters applied automatically

Code

ssh myserver

Execution

Last login: Wed Feb 28 14:30:00 2026
admin@myserver:~$

Reads from ~/.ssh/config automatically
Command line options override config file

Jump Host / Bastion Configuration

Use ProxyJump to tunnel through bastion host to reach internal servers. Cleaner than -J flag

Code

Host bastion
  HostName bastion.company.com
  User bastionuser

Host internal-*.company.com
  ProxyJump bastion
  User internaluser

ssh internal-db.company.com

Execution

(SSH connects through bastion automatically)
Last login: Wed Feb 28 15:00:00 2026
internaluser@internal-db:~$

ProxyJump added in OpenSSH 7.3
Can chain multiple jumps: ProxyJump host1,host2

Connection Multiplexing

Reuse SSH connections for faster subsequent logins

Enable Connection Multiplexing

Enable multiplexing globally. Auto reuses master connections for 1 hour

Code

# Add to ~/.ssh/config
Host *
  ControlMaster auto
  ControlPath ~/.ssh/control-%h-%r-%p
  ControlPersist 3600

Execution

(settings saved)

ControlMaster auto: automatically create master on first connection
ControlPath: location of control socket
ControlPersist 3600: keep master alive for 1 hour after last client

Multiple Connections Using Master

Second and subsequent connections reuse the master SSH tunnel, bypassing authentication

Code

# First connection (creates master)
ssh user@host

# In another terminal: reuses existing connection
ssh user@host

Execution

(second connection opens instantly)

Dramatically faster since TCP/auth already done
Check control sockets: ls -la ~/.ssh/control-*

Explicitly Check Master Connection

Check if multiplexed connection is active to a host

Code

ssh -O check user@host

Execution

Master running (pid=12345)

exit code 0 if master running
Useful for scripts

Security Best Practices

Protecting Your Keys

Keep SSH keys secure from unauthorized access

Fix SSH Directory Permissions

SSH requires specific permissions for security. SSH will refuse keys with wrong permissions

Code

chmod 700 ~/.ssh
chmod 600 ~/.ssh/id_*
chmod 600 ~/.ssh/authorized_keys
chmod 644 ~/.ssh/*.pub

Execution

(permissions updated)

~/.ssh directory: 700 (rwx------)
Private key files: 600 (rw-------)
Public key files: 644 (rw-r--r--)
authorized_keys: 600 (rw-------)

Test Key Permissions

Verify all permissions are correct. Private keys only readable by owner

Code

ls -la ~/.ssh/

Execution

total 32
drwx------ 2 user user 4096 Feb 28 10:30 .
-rw------- 1 user user  464 Feb 28 10:30 id_ed25519
-rw-r--r-- 1 user user   89 Feb 28 10:30 id_ed25519.pub
-rw------- 1 user user 1679 Feb 28 10:30 authorized_keys

First column shows permissions
Directory should start with 'd'
Private keys should be 'rw-------'

Rotate Compromised Key

After compromise, remove old key from all authorized_keys and generate new one

Code

# Step 1: Remove old key from authorized_keys on all servers
grep -l "old_key_fingerprint" ~/.ssh/authorized_keys | while read f; do
  sed -i '/old_key_fingerprint/d' "$f"
done

# Step 2: Delete local private key
rm ~/.ssh/id_rsa

# Step 3: Generate new key
ssh-keygen -t ed25519 -C "new-key"

Execution

(key rotated)

Must rotate across all servers
May need temporary password access to add new key

Host Key Verification

Verify remote host authenticity to prevent MITM attacks

First Connection Host Key Verification

On first connection, SSH shows host key fingerprint for verification. Accept only if verified from trusted source

Code

ssh user@newhost

Execution

The authenticity of host 'newhost (192.168.1.100)' can't be established.
ED25519 key fingerprint is SHA256:abcxy123...
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])?

Fingerprint should match official host key
Answer 'yes' to add to ~/.ssh/known_hosts
Subsequent connections won't show this prompt

Verify Host Key Fingerprint Manually

Verify fingerprint matches what SSH showed during connection attempt

Code

# On the remote host
ssh-keygen -l -f /etc/ssh/ssh_host_ed25519_key.pub

Execution

256 SHA256:abcxy123... root@newhost (ED25519)

Run on remote server admin console
Compare with fingerprint displayed during SSH connection

Check Existing Host Key

Display all known host keys and their fingerprints from ~/.ssh/known_hosts

Code

ssh-keygen -l -f ~/.ssh/known_hosts

Execution

256 SHA256:old_key... hostname1 (ED25519)
256 SHA256:new_key... hostname2 (ED25519)

Helps identify if host key has changed
Unexpected changes may indicate compromise or reconfiguration

Advanced Usage

Jump Hosts & Bastion Patterns

Connect through intermediate hosts to reach internal servers

Single Hop Through Jump Host

Use jump host to reach internal server. SSH tunnels through bastion automatically

Code

ssh -J user@bastion:2222 user@internal-server

Execution

Last login: Wed Feb 28 16:30:00 2026
user@internal-server:~$

Format: -J [user@]host[:port]
Can specify non-standard port on jump host
Automatically applies ProxyCommand

Multiple Hops Through Jump Hosts

Chain multiple jump hosts. Connection routes through bastion1 -> bastion2 -> final-host

Code

ssh -J user@bastion1,user@bastion2 user@final-host

Execution

(connected through chain of hosts)
user@final-host:~$

Separate hosts with commas
Each hop authenticates independently

Persistent Jump Host Configuration

Configure jump host in ~/.ssh/config for permanent setup. All internal-* hosts use bastion

Code

Host bastion
  HostName bastion.company.com
  User admin

Host internal-*
  ProxyJump bastion
  User devuser

# Usage: ssh internal-server1

Execution

(automatic jump through bastion)

ProxyJump simpler than older ProxyCommand
Inherits authentication from config

X11 Forwarding

Run graphical applications on remote servers and display locally

Enable X11 Forwarding

Forward X11 display from remote to local machine. Start GUI apps on remote, see them locally

Code

ssh -X user@remote-host

Execution

user@remote-host:~$ gedit &
(gedit window opens on local display)

Requires X11 server on local machine (native on Linux/macOS)
-X: standard X11 forwarding
-Y: trusted X11 forwarding (skips security checks)

Trusted X11 Forwarding

Trusted X11 forwarding allows apps to access X11 security extensions. Faster but less secure

Code

ssh -Y user@remote-host

Execution

user@remote-host:~$ firefox &
(firefox window opens on local display)

Use for trusted hosts only
-Y skips X11 SECURITY extension
Performance improvement over standard -X

Test X11 Forwarding

DISPLAY variable set by SSH indicates X11 tunnel is active

Code

ssh -X user@remote-host
echo $DISPLAY

Execution

localhost:10.0

DISPLAY set to localhost:N where N > 0
Value 0 would indicate no X11 forwarding

Practical Real-World Examples

Common Use Cases

Real-world examples and practical patterns

Copy Files Using SCP

SCP (secure copy) transfers files through SSH tunnel. Secure alternative to FTP

Code

# Copy file from local to remote
scp /local/path/file user@host:/remote/path/

# Copy file from remote to local
scp user@host:/remote/path/file /local/path/

# Copy directory recursively
scp -r user@host:/remote/path/ /local/path/

Execution

file                      100%   1234KB    5.2MB/s   00:00

Uses SSH for encryption
-r flag for recursive directory copy
-P for non-standard port (uppercase!)

Sync Directory with rsync Over SSH

rsync over SSH for efficient file synchronization. Only transfers changed files

Code

# Sync local to remote
rsync -avz -e ssh /local/path/ user@host:/remote/path/

# Sync remote to local
rsync -avz -e ssh user@host:/remote/path/ /local/path/

# With non-standard SSH port
rsync -avz -e 'ssh -p 2222' /local/path/ user@host:/remote/path/

Execution

sending incremental file list
file1
file2
sent 1234 bytes  received 567 bytes
total size is 5678  speedup is 3.21

Much faster than scp for large directories
-a: archive mode (preserves permissions)
-v: verbose, -z: compress
Better for backups and deployments

Run Remote Command and Get Output

Execute remote commands and get output without interactive shell. Useful for scripts

Code

# Execute single command
ssh user@host "ps aux | grep nodejs"

# Execute multiple commands
ssh user@host "cd /app && npm start"

# Run command and capture output
result=$(ssh user@host "docker ps -a")
echo "$result"

Execution

user        12345  0.5 15.3 234567 89012 ?  Sl  14:30   0:05 node /app/server.js

Command in quotes runs on remote, output sent to stdout
Exit code preserved: useful in bash conditionals
Great for cronjobs and automation

Automated Backup to Remote Host

Stream compressed backup to remote server. Efficient and no local temporary files

Code

#!/bin/bash
# backup.sh - automated backup script

LOCAL_PATH="/home/user/important-data"
BACKUP_HOST="backup.example.com"
BACKUP_USER="backup"
BACKUP_PATH="/backups/$(hostname)"

# Create backup
tar czf - "$LOCAL_PATH" | ssh $BACKUP_USER@$BACKUP_HOST \
  "cat > $BACKUP_PATH/backup-$(date +%Y%m%d).tar.gz"

echo "Backup completed"

Execution

Backup completed

tar pipes directly through SSH
No local disk space needed for backup
Useful for cron jobs with SSH key auth

Port Forward for Database Connection

Access private database server through SSH tunnel. Database thinks it's local

Code

# Terminal 1: Create tunnel
ssh -L 3306:internal-db:3306 -N user@bastion

# Terminal 2: Connect to local port
mysql -h localhost -u dbuser -p

Execution

Enter password:
Welcome to MariaDB Monitor. Commands...

-N: don't execute remote command
Keep tunnel running in separate terminal
Connection is end-to-end encrypted

SSH Agent for Automated Deployments

Use SSH agent in scripts for passwordless authentication. Clean up after

Code

#!/bin/bash
# deploy.sh - automated deployment

# Start SSH agent for this script
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/deploy-key

# Deploy to multiple servers
for server in web1 web2 web3; do
  ssh -o StrictHostKeyChecking=accept-new deploy@$server \
    "cd /app && git pull && npm start"
done

# Kill agent when done
ssh-agent -k

Execution

deployment to web1... done
deployment to web2... done
deployment to web3... done

ssh-agent managed within script
StrictHostKeyChecking=accept-new for new hosts
Always kill agent to avoid leaked credentials

Troubleshooting

Debugging SSH Connection Issues

Diagnose and fix common SSH problems

Enable Verbose Output for Debugging

Verbose flags show detailed connection process. Level indicates where connection fails

Code

# Single verbose (-v): shows authentication method
ssh -v user@host

# Double verbose (-vv): shows handshake details
ssh -vv user@host

# Triple verbose (-vvv): shows all details including crypto
ssh -vvv user@host

Execution

OpenSSH_8.0p1 Ubuntu 1:8.0p1-6ubuntu1, OpenSSL 1.1.1
debug1: Reading configuration data /home/user/.ssh/config
debug1: No more authentication methods to try.
Permission denied (publickey,password).

-v: high-level flow
-vv: detailed authentication
-vvv: packet-level (very verbose)

Check SSH Key Permissions

SSH refuses to use keys with improper permissions. Directory 700, private keys 600

Code

# Check directory permissions
ls -ld ~/.ssh

# Check key file permissions
ls -l ~/.ssh/id_*

Execution

drwx------ 2 user user 4096 Feb 28 10:00 /home/user/.ssh
-rw------- 1 user user  1234 Feb 28 10:00 /home/user/.ssh/id_ed25519
-rw-r--r-- 1 user user   456 Feb 28 10:00 /home/user/.ssh/id_ed25519.pub

Private keys must be readable only by owner
Use 'chmod 700 ~/.ssh' and 'chmod 600 ~/.ssh/id_*'

Test Remote SSH Server Configuration

Test which authentication methods server allows. Helpful for debugging auth failures

Code

# List available authentication methods
ssh -o PreferredAuthentications=none user@host

# Test specific auth method
ssh -o PreferredAuthentications=publickey user@host
ssh -o PreferredAuthentications=password user@host

Execution

Permission denied (publickey).
debug1: Authentications that can continue: publickey,password

Shows which methods server supports
Can isolate auth method issues
