Blocking telnet listener on ephemeral port
This is a multi-part message in MIME format.
------_=_NextPart_001_01C8B073.AFF31B72 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hello All - I am running a nessus scan and get an error that a telnet server is listening on an ephemeral port. I cannot turn the telnet listener off on the service running in the ephemeral port range as it is used for inter-process communications on the box. Is there a way to specifically block telnet messages destined for an ephemeral port with ipfilter? Any information would be appreciated, Anna. =20 ------_=_NextPart_001_01C8B073.AFF31B72 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" = xmlns:o=3D"urn:schemas-microsoft-com:office:office" = xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" = xmlns=3D"http://www.w3.org/TR/REC-html40"> <head> <meta http-equiv=3DContent-Type content=3D"text/html; = charset=3Dus-ascii"> <meta name=3DGenerator content=3D"Microsoft Word 12 (filtered medium)"> <style> <!-- /* Font Definitions */ @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0in; margin-bottom:.0001pt; font-size:11.0pt; font-family:"Calibri","sans-serif";} a:link, span.MsoHyperlink {mso-style-priority:99; color:blue; text-decoration:underline;} a:visited, span.MsoHyperlinkFollowed {mso-style-priority:99; color:purple; text-decoration:underline;} span.EmailStyle17 {mso-style-type:personal-compose; font-family:"Calibri","sans-serif"; color:windowtext;} ..MsoChpDefault {mso-style-type:export-only;} @page Section1 {size:8.5in 11.0in; margin:1.0in 1.0in 1.0in 1.0in;} div.Section1 {page:Section1;} --> </style> <!--[if gte mso 9]><xml> <o:shapedefaults v:ext=3D"edit" spidmax=3D"1026" /> </xml><![endif]--><!--[if gte mso 9]><xml> <o:shapelayout v:ext=3D"edit"> <o:idmap v:ext=3D"edit" data=3D"1" /> </o:shapelayout></xml><![endif]--> </head> <body lang=3DEN-US link=3Dblue vlink=3Dpurple> <div class=3DSection1> <p class=3DMsoNormal>Hello All –<o:p></o:p></p> <p class=3DMsoNormal>I am running a nessus scan and get an error that a = telnet server is listening on an ephemeral port.<o:p></o:p></p> <p class=3DMsoNormal>I cannot turn the telnet listener off on the = service running in the ephemeral port range as it is used for inter-process = communications on the box.<o:p></o:p></p> <p class=3DMsoNormal>Is there a way to specifically block telnet = messages destined for an ephemeral port with ipfilter?<o:p></o:p></p> <p class=3DMsoNormal>Any information would be = appreciated,<o:p></o:p></p> <p class=3DMsoNormal>Anna.<o:p></o:p></p> <p class=3DMsoNormal> <o:p></o:p></p> </div> </body> </html> ------_=_NextPart_001_01C8B073.AFF31B72--
