Hey, if you want everything riding on one password, more power to you, but you might want to refrain from using phrases like "stupid myth" unless you've got some hard data to back them up. > simply use good passwords.

The only mess I can think of is all that logging that forces a bit of accountability onto all the admins who know the root password. Of course, if you're the only admin, I suppose it doesn't really matter. ;-) --Jon Radel --------------ms070602050604090109030800 Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="smime.p7s" Content-Description: S/MIME Cryptographic Signature MIAGCSqGSIb3DQEHAqCAMIACAQExCzAJBgUrDgMCGgUAMIAGCSqGSIb3DQEHAQAAoIIJMTCC AvMwggJcoAMCAQICEG2TkfF/93Sx9LCftry1D3YwDQYJKoZIhvcNAQEFBQAwYjELMAkGA1UE BhMCWkExJTAjBgNVBAoTHFRoYXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4xLDAqBgNVBAMT I1RoYXd0ZSBQZXJzb25hbCBGcmVlbWFpbCBJc3N1aW5nIENBMB4XDTA4MDMyNDE2NTkyMVoX DTA5MDMyNDE2NTkyMVowXjEOMAwGA1UEBBMFUmFkZWwxEzARBgNVBCoTCkpvbiBUaG9tYXMx GTAXBgNVBAMTEEpvbiBUaG9tYXMgUmFkZWwxHDAaBgkqhkiG9w0BCQEWDWpvbkByYWRlbC5j b20wggEiMA0GCSqGSIb3DQEBAQUAA4IBDwAwggEKAoIBAQDPdCxQufreHHDAI9YN2axx87Rf 0TK1PYFMlJHi4y1ebdAMPqR6M44bz+3m8YnKn1bmIf7dWyisWyAIQYCOhW/2r66o4MdF9qJ9 z5uhMy+28zaJP/Glg64C3WPM0VfveCgvu+ApEyf2JDbjc/hUomw8KpppgOcn1wX6PZGbhHVv eAvDTWJ0ugqo08Ny6GR0bsGvePmxdWSQq+0aGTHqA1I2EozJBZ8W5xlUtKe22j56i1Uw1ujk Rlosdu2PTs8QOY1OUHuLPnEV9EWtYF7g6bXDUDsJxypXZy9qTipPplYXjdWgkLVRvezri+BN kgin8UKhKLQ99vS25zrMFKu80g31AgMBAAGjKjAoMBgGA1UdEQQRMA+BDWpvbkByYWRlbC5j b20wDAYDVR0TAQH/BAIwADANBgkqhkiG9w0BAQUFAAOBgQAR4u9o4CFvztyo0sZb3tCQIWYb 5U4jW9da3goVwWIkMz+qeCb2kiTQfsSmOdF9YJ8VTRdYW0l0fQbqL5JikVhaYeX85cpqZ3iA /PPJpfPtJw8g5jJOAROVAvxydMZXQYxyIBMV4HNG3qir44YnyfmJXkBtRFYWdxBc7bQpoZSZ jzCCAvMwggJcoAMCAQICEG2TkfF/93Sx9LCftry1D3YwDQYJKoZIhvcNAQEFBQAwYjELMAkG A1UEBhMCWkExJTAjBgNVBAoTHFRoYXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4xLDAqBgNV BAMTI1RoYXd0ZSBQZXJzb25hbCBGcmVlbWFpbCBJc3N1aW5nIENBMB4XDTA4MDMyNDE2NTky MVoXDTA5MDMyNDE2NTkyMVowXjEOMAwGA1UEBBMFUmFkZWwxEzARBgNVBCoTCkpvbiBUaG9t YXMxGTAXBgNVBAMTEEpvbiBUaG9tYXMgUmFkZWwxHDAaBgkqhkiG9w0BCQEWDWpvbkByYWRl bC5jb20wggEiMA0GCSqGSIb3DQEBAQUAA4IBDwAwggEKAoIBAQDPdCxQufreHHDAI9YN2axx 87Rf0TK1PYFMlJHi4y1ebdAMPqR6M44bz+3m8YnKn1bmIf7dWyisWyAIQYCOhW/2r66o4MdF 9qJ9z5uhMy+28zaJP/Glg64C3WPM0VfveCgvu+ApEyf2JDbjc/hUomw8KpppgOcn1wX6PZGb hHVveAvDTWJ0ugqo08Ny6GR0bsGvePmxdWSQq+0aGTHqA1I2EozJBZ8W5xlUtKe22j56i1Uw 1ujkRlosdu2PTs8QOY1OUHuLPnEV9EWtYF7g6bXDUDsJxypXZy9qTipPplYXjdWgkLVRvezr i+BNkgin8UKhKLQ99vS25zrMFKu80g31AgMBAAGjKjAoMBgGA1UdEQQRMA+BDWpvbkByYWRl bC5jb20wDAYDVR0TAQH/BAIwADANBgkqhkiG9w0BAQUFAAOBgQAR4u9o4CFvztyo0sZb3tCQ IWYb5U4jW9da3goVwWIkMz+qeCb2kiTQfsSmOdF9YJ8VTRdYW0l0fQbqL5JikVhaYeX85cpq Z3iA/PPJpfPtJw8g5jJOAROVAvxydMZXQYxyIBMV4HNG3qir44YnyfmJXkBtRFYWdxBc7bQp oZSZjzCCAz8wggKooAMCAQICAQ0wDQYJKoZIhvcNAQEFBQAwgdExCzAJBgNVBAYTAlpBMRUw EwYDVQQIEwxXZXN0ZXJuIENhcGUxEjAQBgNVBAcTCUNhcGUgVG93bjEaMBgGA1UEChMRVGhh d3RlIENvbnN1bHRpbmcxKDAmBgNVBAsTH0NlcnRpZmljYXRpb24gU2VydmljZXMgRGl2aXNp b24xJDAiBgNVBAMTG1RoYXd0ZSBQZXJzb25hbCBGcmVlbWFpbCBDQTErMCkGCSqGSIb3DQEJ ARYccGVyc29uYWwtZnJlZW1haWxAdGhhd3RlLmNvbTAeFw0wMzA3MTcwMDAwMDBaFw0xMzA3 MTYyMzU5NTlaMGIxCzAJBgNVBAYTAlpBMSUwIwYDVQQKExxUaGF3dGUgQ29uc3VsdGluZyAo UHR5KSBMdGQuMSwwKgYDVQQDEyNUaGF3dGUgUGVyc29uYWwgRnJlZW1haWwgSXNzdWluZyBD QTCBnzANBgkqhkiG9w0BAQEFAAOBjQAwgYkCgYEAxKY8VXNV+065yplaHmjAdQRwnd/p/6Me 7L3N9VvyGna9fww6YfK/Uc4B1OVQCjDXAmNaLIkVcI7dyfArhVqqP3FWy688Cwfn8R+RNiQq E88r1fOCdz0Dviv+uxg+B79AgAJk16emu59l0cUqVIUPSAR/p7bRPGEEQB5kGXJgt/sCAwEA AaOBlDCBkTASBgNVHRMBAf8ECDAGAQH/AgEAMEMGA1UdHwQ8MDowOKA2oDSGMmh0dHA6Ly9j cmwudGhhd3RlLmNvbS9UaGF3dGVQZXJzb25hbEZyZWVtYWlsQ0EuY3JsMAsGA1UdDwQEAwIB BjApBgNVHREEIjAgpB4wHDEaMBgGA1UEAxMRUHJpdmF0ZUxhYmVsMi0xMzgwDQYJKoZIhvcN AQEFBQADgYEASIzRUIPqCy7MDaNmrGcPf6+svsIXoUOWlJ1/TCG4+DYfqi2fNi/A9BxQIJNw PP2t4WFiw9k6GX6EsZkbAMUaC4J0niVQlGLH2ydxVyWN3amcOY6MIE9lX5Xa9/eH1sYITq72 6jTlEBpbNU1341YheILcIRk13iSx0x1G/11fZU8xggNkMIIDYAIBATB2MGIxCzAJBgNVBAYT AlpBMSUwIwYDVQQKExxUaGF3dGUgQ29uc3VsdGluZyAoUHR5KSBMdGQuMSwwKgYDVQQDEyNU aGF3dGUgUGVyc29uYWwgRnJlZW1haWwgSXNzdWluZyBDQQIQbZOR8X/3dLH0sJ+2vLUPdjAJ BgUrDgMCGgUAoIIBwzAYBgkqhkiG9w0BCQMxCwYJKoZIhvcNAQcBMBwGCSqGSIb3DQEJBTEP Fw0wODA1MTEyMTM0NDFaMCMGCSqGSIb3DQEJBDEWBBQv8MqoUpm2sUY13DhI5IQGjfoRdDBS BgkqhkiG9w0BCQ8xRTBDMAoGCCqGSIb3DQMHMA4GCCqGSIb3DQMCAgIAgDANBggqhkiG9w0D AgIBQDAHBgUrDgMCBzANBggqhkiG9w0DAgIBKDCBhQYJKwYBBAGCNxAEMXgwdjBiMQswCQYD VQQGEwJaQTElMCMGA1UEChMcVGhhd3RlIENvbnN1bHRpbmcgKFB0eSkgTHRkLjEsMCoGA1UE AxMjVGhhd3RlIFBlcnNvbmFsIEZyZWVtYWlsIElzc3VpbmcgQ0ECEG2TkfF/93Sx9LCftry1 D3YwgYcGCyqGSIb3DQEJEAILMXigdjBiMQswCQYDVQQGEwJaQTElMCMGA1UEChMcVGhhd3Rl IENvbnN1bHRpbmcgKFB0eSkgTHRkLjEsMCoGA1UEAxMjVGhhd3RlIFBlcnNvbmFsIEZyZWVt YWlsIElzc3VpbmcgQ0ECEG2TkfF/93Sx9LCftry1D3YwDQYJKoZIhvcNAQEBBQAEggEAXlCC AzVXwbrI0iv5Po2aPSSNSZJUQhNUDKWG2KSm6nLGsV+4aZRehuUhMNDXFjST2mV7ikQKSTuE rrQqh7zE+DWGwPy5Goi895E94n/bDT/8H2ghr7SRoOPQYqU0woECgiu9tAip4VePDSILXu8t LMK6POejZXylmABccVq8AW1qN2LI62vjqyKv4IyCg9GaX9zuOEmQWj2o7x2wk8CBV0nx4i9L QxQkOFIZSRDWp7RUNBSw0tQLbUk3Z8xq+Fmt+D8PWFr8uQW6I1BmMugs1tsa6dv2jL4/4+aD Zuyvgz4Cwlo6Adnt6GCqa1UrmpRweAr6NAF8t6cn+YHrsQ3+2gAAAAAAAA== --------------ms070602050604090109030800--
