# For CentOS/RHEL
sudo yum install vinagre

# For Fedora
sudo dnf install vinagre

Arch Linux

sudo pacman -S vinagre

Basic vinagre Command Syntax

The basic syntax for the vinagre command is:

vinagre [OPTIONS] [CONNECTION]

Where:

OPTIONS are command-line flags that modify behavior
CONNECTION is the remote server address or connection file

Common vinagre Command Options

Option	Description
`-h, --help`	Display help information
`-v, --version`	Show version information
`-F, --file`	Open a connection file
`-f, --fullscreen`	Start in full-screen mode
`-n, --new-window`	Open connection in new window
`--geometry`	Set window geometry

Practical vinagre Examples

Example 1: Basic VNC Connection

Connect to a VNC server running on IP address 192.168.1.100:

vinagre 192.168.1.100

Expected Output:

Opening VNC connection to 192.168.1.100:5900
Connecting...
Authentication required
[Password prompt appears]

Example 2: Connect with Specific Port

Connect to a VNC server on a custom port:

vinagre 192.168.1.100:5901

This connects to VNC display :1 (port 5901) instead of the default :0 (port 5900).

Example 3: Full-Screen Connection

Start vinagre in full-screen mode:

vinagre -f 192.168.1.100

Visual Result: The remote desktop opens immediately in full-screen mode, providing an immersive experience.

Example 4: SSH Connection

Connect via SSH protocol:

vinagre ssh://[email protected]

Expected Output:

Establishing SSH connection to 192.168.1.100
Username: username
Password: [hidden]
Connected successfully

Example 5: RDP Connection

Connect to a Windows machine using RDP:

vinagre rdp://192.168.1.100

Advanced vinagre Usage

Using Connection Files

You can save connection details in a file and load it later:

# Create a connection file
echo "vnc://192.168.1.100:5900" > my_server.vnc

# Load the connection file
vinagre -F my_server.vnc

Setting Window Geometry

Control the initial window size and position:

vinagre --geometry=800x600+100+50 192.168.1.100

This opens a 800×600 pixel window positioned 100 pixels from the left and 50 pixels from the top of the screen.

Managing Bookmarks

Vinagre provides a bookmark system for frequently accessed connections:

Adding Bookmarks

Open vinagre GUI (run vinagre without arguments)
Go to Bookmarks → Add Bookmark
Fill in connection details:
- Name: Descriptive name for the connection
- Protocol: VNC, SSH, RDP, or SPICE
- Host: IP address or hostname
- Port: Connection port (optional)

Using Bookmarks from Command Line

Access bookmarked connections:

vinagre bookmark://MyServer

Security Considerations

VNC Security

VNC connections are not encrypted by default. For secure connections, consider:

SSH Tunneling: Route VNC through SSH
VPN: Use VPN for network-level encryption
TLS Encryption: Enable if supported by VNC server

SSH Tunneling Example

# Create SSH tunnel
ssh -L 5900:localhost:5900 user@remote-server

# Connect through tunnel
vinagre localhost:5900

Troubleshooting Common Issues

Connection Refused

Problem: “Connection refused” error

Solutions:

Verify VNC server is running on target machine
Check firewall settings on both machines
Confirm correct IP address and port

# Check if VNC server is listening
nmap -p 5900 192.168.1.100

# Test connection with netcat
nc -zv 192.168.1.100 5900

Authentication Failures

Problem: Authentication repeatedly fails

Solutions:

Verify VNC password is correct
Check VNC server authentication settings
Try connecting with different VNC client to isolate issue

Display Issues

Problem: Black screen or corrupted display

Solutions:

Check color depth settings
Verify screen resolution compatibility
Try different VNC encoding methods

Performance Optimization

Network Optimization

For better performance over slow connections:

Reduce color depth: Use 8-bit color instead of 24-bit
Lower resolution: Use smaller screen resolution
Compression: Enable VNC compression if available

Local Performance

Optimize local system performance:

# Check system resources
htop

# Monitor network usage
iftop

# Check vinagre process
ps aux | grep vinagre

Integration with Other Tools

Scripting vinagre Connections

Create automated connection scripts:

#!/bin/bash
# connect_to_server.sh

SERVER_IP="192.168.1.100"
PORT="5900"

echo "Connecting to VNC server at $SERVER_IP:$PORT"
vinagre -f $SERVER_IP:$PORT

Desktop Integration

Create desktop shortcuts for frequent connections:

# Create .desktop file
cat > ~/Desktop/MyServer.desktop << EOF
[Desktop Entry]
Version=1.0
Type=Application
Name=My VNC Server
Comment=Connect to my VNC server
Exec=vinagre 192.168.1.100
Icon=vinagre
Terminal=false
Categories=Network;RemoteAccess;
EOF

Alternative VNC Viewers

While vinagre is excellent for GNOME environments, consider these alternatives:

TigerVNC Viewer: Cross-platform, high performance
