dhcp to get their IP address. In this case, they may not always have the
same IP address, so you should use their hostname instead of an IP address in
your sshd_config file. Since the windows boxes automatically update their
DNS registration, their hostname, via DNS lookup, will always match the IP
address they are using when a connection attempt is made.<o:p></o:p></span></font></p>

all,<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>I
am in a mixed environment and I have 2 admins that connect to my RHEL AS4
machines using windows. In their windows setup, there is a setting “Register
this connections addresses in DNS” which registers the computer name to
the IP address. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>For
my Linux system there is no such setting that I am aware of. I have SSH
configures so that each admin can only SSH to the server from their
administrative desktop IP address. So in the sshd_config file I have <a
href="mailto:denise@192.168.1.1">denise@192.168.1.1</a>. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>My
question is this: For the admins running windows sometimes I need to add
the DNS name in addition to the IP address in the sshd_config file.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>Does
anyone know why that is? Also I wonder if I had an entry in DNS for my
Linux system if I would need the additional entry as well.<o:p></o:p></span></font></p>
