This is a multi-part message in MIME format. ------=_NextPart_000_002E_01C1BEC9.74C29E20 Content-Type: text/plain; Content-Transfer-Encoding: quoted-printable I would appreciate any help with this issue: I'm using ipfw on two machines, both running FreeBSD 4.5 RELEASE. At both machines the following rules apply: ipfw add pass tcp from A to B 22 ipfw add pass tcp form B to A 22 A and B being the respective IP addresses of the machines! Surprisingly, when I tried to log from each of the machines into the = other, the ipfw wouldn't pass any tcp through. The login format is as per usual: ssh username@A ssh usernamer@B Thanks in anticipation, Adam ______________________________________ Scanned and protected by Inflex http://pldaniels.com/inflex ------=_NextPart_000_002E_01C1BEC9.74C29E20 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 6.00.2600.0" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial color=3D#0000ff> I would appreciate = any=20 help with this issue: <DIV><FONT face=3DArial color=3D#0000ff></FONT> </DIV> <DIV><FONT face=3DArial color=3D#0000ff>I'm using ipfw on two machines, = both running=20 FreeBSD 4.5 RELEASE.</FONT></DIV> <DIV><FONT face=3DArial color=3D#0000ff>At both machines the following = rules=20 apply:</FONT></DIV> <DIV><FONT face=3DArial color=3D#0000ff>ipfw add pass tcp from A to B=20 22</FONT></DIV> <DIV><FONT face=3DArial color=3D#0000ff>ipfw add pass tcp form B to A=20 22</FONT></DIV> <DIV><FONT face=3DArial color=3D#0000ff>A and B being the = respective IP=20 addresses of the machines!</FONT></DIV> <DIV><FONT face=3DArial color=3D#0000ff></FONT> </DIV> <DIV><FONT face=3DArial color=3D#0000ff>Surprisingly, when I tried to = log from each=20 of the machines into the other, the ipfw wouldn't pass any tcp=20 through.</FONT></DIV> <DIV><FONT face=3DArial color=3D#0000ff></FONT> </DIV> <DIV><FONT face=3DArial color=3D#0000ff></FONT> </DIV> <DIV><FONT face=3DArial color=3D#0000ff>The login format is as per=20 usual:</FONT></DIV> <DIV><FONT face=3DArial color=3D#0000ff></FONT> </DIV> <DIV><FONT face=3DArial color=3D#0000ff>ssh <A=20 href=3D"mailto:username@A">username@A</A></FONT></DIV> <DIV><FONT face=3DArial color=3D#0000ff>ssh <A=20 href=3D"mailto:usernamer@B">usernamer@B</A></FONT></DIV> <DIV><FONT face=3DArial color=3D#0000ff></FONT> </DIV> <DIV><FONT face=3DArial color=3D#0000ff></FONT> </DIV> <DIV><FONT face=3DArial color=3D#0000ff>Thanks in = anticipation,</FONT></DIV> <DIV><FONT face=3DArial color=3D#0000ff>Adam</FONT></DIV> <DIV> </DIV></FONT></DIV> <PRE> ______________________________________ Scanned and protected by Inflex http://pldaniels.com/inflex </pre> </BODY></HTML> ------=_NextPart_000_002E_01C1BEC9.74C29E20-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
