SSH connection without welcome message or banner

Suppress SSH banners, welcome messages, and diagnostic output using the -q (quiet) flag.

Quiet mode: `-q` flag

ssh -q user@hostname
ssh -q user@hostname "command"

Suppresses:

Banner messages
Warning messages
Diagnostic output

Multiple verbose levels

ssh -q user@hostname       # Quiet (minimal output)
ssh user@hostname          # Normal (default)
ssh -v user@hostname       # Verbose (debug info)
ssh -vv user@hostname      # More verbose
ssh -vvv user@hostname     # Maximum verbose

SSH config file approach

For persistent suppression, add to ~/.ssh/config:

Host myserver
    Hostname example.com
    User myuser
    LogLevel QUIET

Then use:

ssh myserver

The server sends banner in /etc/ssh/banner or configured location. To suppress:

ssh -q user@hostname  # Quiet mode
ssh -o "LogLevel=QUIET" user@hostname  # Explicit log level
ssh -o "Banner=none" user@hostname  # Disable banner (if server allows)

With commands (clean output)

Useful for scripts/automation where you only want command output:

ssh -q user@hostname "ls -la /tmp"
output=$(ssh -q user@hostname "cat file.txt")

Combined with other options

ssh -q -i ~/.ssh/key -p 2222 user@hostname
ssh -q -o ConnectTimeout=5 user@hostname "echo test"
ssh -q -T user@hostname < script.sh

Note

The -q flag controls local SSH client messages, not server-side banner. If the server sends a banner, you may still see it. For full suppression at server level, the admin must configure /etc/ssh/sshd_config with Banner none.
