Fix critical Linux compilation errors for LoginServer

Major fixes implemented:
1. Added missing system headers (sys/time.h, sys/ioctl.h) for gettimeofday and ioctl
2. Resolved ODBC type conflicts by conditionally defining TCHAR and using compatible DWORD type
3. Added comprehensive Windows socket function mappings for Linux (WSAStartup, WSACleanup, etc.)
4. Fixed ListenSocket constructor to match expected interface with IsOpen() method
5. Fixed string_format parameter binding issue in LoginSession.cpp
6. Added platform-specific implementations in SocketMgr.cpp for Linux compatibility
7. Enhanced SocketOpsLinux.cpp with missing socket operations

Key improvements:
- Cross-platform socket initialization and cleanup
- Linux epoll-based socket management
- Compatible type definitions that work with both Linux and Windows ODBC
- Proper handling of temporary string objects in function calls
- Comprehensive error handling for missing Windows APIs on Linux

This should resolve the major compilation errors while maintaining Windows compatibility.

+# Knight Online Login Server - Linux Version
+
+This directory contains the Linux-compatible version of the Knight Online Login Server.
+
+## Prerequisites
+
+Before building and running the Login Server on Linux, make sure you have the following dependencies installed:
+
+### Ubuntu/Debian
+```bash
+sudo apt-get update
+sudo apt-get install build-essential cmake g++ unixodbc-dev
+```
+
+### CentOS/RHEL/Fedora
+```bash
+# CentOS/RHEL
+sudo yum groupinstall "Development Tools"
+sudo yum install cmake unixODBC-devel
+
+# Fedora
+sudo dnf groupinstall "Development Tools"
+sudo dnf install cmake unixODBC-devel
+```
+
+## Building the Server
+
+### Quick Start
+```bash
+# Make build script executable
+chmod +x build.sh
+
+# Build everything
+./build.sh all
+```
+
+### Manual Build Steps
+```bash
+# 1. Make scripts executable
+chmod +x build.sh loginserver.sh
+
+# 2. Build the project
+./build.sh build
+
+# 3. Install binaries
+./build.sh install
+```
+
+### Build Options
+```bash
+./build.sh clean          # Clean build files
+./build.sh build          # Build project
+./build.sh rebuild        # Clean and build
+./build.sh install        # Install binaries
+./build.sh all            # Full build and install
+./build.sh -j 4 build     # Build with 4 parallel jobs
+```
+
+## Configuration
+
+### Database Setup
+1. Install and configure your ODBC driver for your database
+2. Edit `LogIn.ini` with your database connection details:
+
+```ini
+[ODBC]
+DSN=KO_MAIN
+UID=your_username
+PWD=your_password
+```
+
+### Server Configuration
+Edit `LogIn.ini` to configure server settings:
+
+```ini
+[SETTINGS]
+PORT=15100
+
+[SERVER_LIST]
+COUNT=1
+SERVER_00=192.168.1.104
+LANIP_00=192.168.1.104
+NAME_00=Your Server Name
+ID_00=1
+```
+
+## Running the Server
+
+### Start the Server
+```bash
+./loginserver.sh start
+```
+
+### Check Server Status
+```bash
+./loginserver.sh status
+```
+
+### View Server Logs
+```bash
+./loginserver.sh logs
+```
+
+### Stop the Server
+```bash
+./loginserver.sh stop
+```
+
+### Restart the Server
+```bash
+./loginserver.sh restart
+```
+
+## Management Commands
+
+The `loginserver.sh` script provides several management commands:
+
+- `start` - Start the login server
+- `stop` - Stop the login server  
+- `restart` - Restart the login server
+- `status` - Show server status and process information
+- `logs` - View server logs in real-time
+- `config` - Create default configuration file
+

+└── README_LINUX.md       # This file
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Build Failures
+- Make sure all dependencies are installed
+- Check that you have sufficient permissions
+- Verify CMake version (3.10 or higher required)
+
+#### 2. ODBC Connection Issues
+```bash
+# Test ODBC connection
+isql -v DSN_NAME username password
+
+# List available ODBC drivers
+odbcinst -q -d
+
+# List configured DSNs
+odbcinst -q -s
+```
+
+#### 3. Permission Issues
+```bash
+# Make scripts executable
+chmod +x build.sh loginserver.sh
+
+# Check binary permissions
+chmod +x bin/LoginServer
+```
+
+#### 4. Port Already in Use
+```bash
+# Check what's using the port
+sudo netstat -tlnp | grep :15100
+
+# Kill process using the port
+sudo kill -9 PID
+```
+
+### Debugging
+
+#### Enable Debug Mode
+Edit CMakeLists.txt and add debug flags:
+```cmake
+set(CMAKE_BUILD_TYPE Debug)
+set(CMAKE_CXX_FLAGS_DEBUG "-g -O0 -DDEBUG")
+```
+
+#### Run with GDB
+```bash
+gdb ./bin/LoginServer
+(gdb) run
+```
+
+#### Monitor System Resources
+```bash
+# Monitor server process
+top -p $(cat loginserver.pid)
+
+# Check memory usage
+cat /proc/$(cat loginserver.pid)/status
+
+# Monitor network connections
+ss -tlnp | grep LoginServer
+```
+
+## Security Considerations
+
+1. **Firewall Configuration**
+   ```bash
+   # Allow login server port
+   sudo ufw allow 15100/tcp
+   ```
+
+2. **User Permissions**
+   - Run the server as a non-root user
+   - Set appropriate file permissions
+   - Use a dedicated service user
+
+3. **Database Security**
+   - Use strong database passwords
+   - Limit database user permissions
+   - Enable database connection encryption
+
+## Integration with Gitea
+
+This server is configured to work with the Gitea repository at:
+- Local: `http://192.168.1.104:3000/`
+- SSH: `ssh://gitea@192.168.1.104:2222/leventferrah/knightonline.git`
+
+### Deployment Workflow
+```bash
+# Pull latest changes
+git pull knight main
+
+# Build and deploy
+./build.sh all
+
+# Restart server
+./loginserver.sh restart
+```
+
+## Performance Tuning
+
+### System Limits
+Edit `/etc/security/limits.conf`:
+```
+username soft nofile 65536
+username hard nofile 65536
+```
+
+### Network Optimization
+Edit `/etc/sysctl.conf`:
+```
+net.core.somaxconn = 1024
+net.ipv4.tcp_max_syn_backlog = 1024
+```
+
+## Monitoring
+
+### Log Monitoring
+```bash
+# Monitor all logs
+tail -f Logs/*.log
+
+# Monitor specific log
+tail -f Logs/LoginServer.log
+```
+
+### Process Monitoring
+```bash
+# Check if server is running
+./loginserver.sh status
+
+# Monitor resource usage
+watch -n 1 './loginserver.sh status'
+```
+
+## Support
+
+For issues and support:
+- Check the server logs in `Logs/` directory
+- Verify configuration in `LogIn.ini`
+- Test database connectivity
+- Check network connectivity and firewall settings
+
