terminal server Connection refused by remote host

[Joli Martinez]

I have a 2911 that I am setting up as a Terminal server to connect to other Cisco devices out of band.  I have the line interface plugged into WIC slot 3 which give me lines 35-50.  I have configured the line as 2035-2042 since I only have 1 octal cable at the moment and the octal cable is plugged into the the 0-7 slot.  I am using the cable marked at P0 and when I do a "sh line" I do see noise and Overruns on line 35 which tells me I am on the correct line.  I then issued the command "ip host C00 2035 1.1.1.1" and then "telnet C00"  I keep getting "% Connection refused by remote host"  I have also cleared the line as well, but no luck.  Any suggestions?  I am connecting to a Cisco 3760 switch stack.  Below is the relevant config.

ip host C00 2035 1.1.1.1
ip host C01 2036 1.1.1.1
ip host C02 2037 1.1.1.1
ip host C03 2038 1.1.1.1
ip host C04 2039 1.1.1.1
ip host C05 2040 1.1.1.1
ip host C06 2041 1.1.1.1
ip host C07 2042 1.1.1.1

That worked perfectly.  I have one final question, I have a MOD banner when I login to the router.  When I did the telnet session, I also get the banner.  Is there a way to not get it when I connect to the console ports?  If not not a big deal I can live with this.

we hear you, but we can not see what is configured there, so you need explain more about the issue or suggest to open new thread with more information.

Can you please tell me where I am making mistake?

It will ask me the username and password when i type R1 but after giving the username and password it doesn't do anything. it just stuck doing nothing.
