Here is the question incase, you missed it.
>Please HELP! I am really stuck. I have an Ultra 1 running 2.5.1 with
>all the latest patches. (The error occurred even before the patches were
>added) The machine is has a netmask of 255.255.255.240 and it is the
only
>machine running on that subnet. The only thing between the machine and
>the router is a hub.
> Now, the problem. I am able to telnet into that machine through the
>broadcast address. We have three networks that have access to the
>machine and all can telnet into the broadcast address. The IP address
is
>xxx.xxx.xx.173 and the broadcast address is xxx.xxx.xx.175. When I
telnet
>into either address I get the same machine name and the same accounts
>work. For some reason either the Sun box is answering to .175 or the
>router is sending .175 to .173. I have had Cisco check the routing
>tables on the router and he says they are fine. I have also had a
>conference call with Sun and Cisco and both agree the broadcast address
>is correct for that subnet.
> I have tried changing the IP address, reloading the OS, Sys-unconfig
>the machine, and changing the hostname but nothing has worked.
> I have also checked the ifconfig -a, /etc/hosts, netstat table, arp
>table, /etc/services and they all appear normal. When I do a snoop of
the
>connection to .173 I see the machine name going back and forth to my IP
>address. When I snoop .175 I see the IP address going to my IP address
>not the name. I'm not sure if that is important? Another note, this
>machine is a standalone not running DNS or NIS. The network I am coming
>from is running NIS+ but we do not have that machine added to our DNS or
>NIS+ on any network. We can only get in by IP address.
> I have open tickets with both Sun and Cisco but neither has been able
to
>help. I am very concerned because this is suppose to be a secure
>machine. If you need any more information please e-mail me. I will
>summarize any answers. Thank you in advance!
