syslog is not supported on windows

Error message

syslog is not supported on windows

What it means

vtorc supports writing audit log entries to syslog in addition to normal logging, but the Windows build (audit_dao_nosyslog.go) has no syslog support. EnableAuditSyslog is a stub that immediately returns this error.

Solutions

1. Disable syslog audit output in the vtorc configuration on Windows
2. Use file-based audit logging instead (audit file destination settings)
3. Run vtorc on a Linux host where syslog is supported

Example fix

// before
vtorc --audit-to-syslog=true ...
// after
vtorc --audit-to-syslog=false --audit-to-file /var/log/vtorc-audit.log ...

if runtime.GOOS == "windows" && auditToSyslog {
    return errors.New("syslog auditing unsupported on windows")
}

When it happens

Trigger: Configuring vtorc with audit syslog enabled (e.g. --audit-to-syslog or the OrcAuditToSyslog setting) on a Windows build, so run() calls EnableAuditSyslog().

Common situations: Running vtorc on Windows with a config copied from a Linux deployment that enabled syslog auditing.
