Trying R1 (172.16.1.1, 2001)...
% Connection refused by remote host

but I'm able to connect to my FRS w/o a problem

ACCESS_SERV# show sessions
Conn Host                Address             Byte  Idle Conn Name
*  1 FRS                 172.16.1.1             0     4 FRS

weird!? I did a quick reload on the 2511 and for some reason now i can connect to R1 thru R4 but can't connect to FRS or my on 2924-M

did you add the command "no exec" to the lnes? If there is line noise on the connection it can cause the term server to spawn an exec session on the line.

Enable telnet with a password on the router. You cant telnet into a router that does not have a telnet password.

he doesnt need telnet password on a 2511 using reverse telnet fromthe 2511
how do i now? i have a 2511 with reverse telnet and octal cable and works fine with
no passsword

makes sure youre reverse telnet config is correct and the sequence numbers used
correspond to the cables that is important you said you are cabling
your new lab there is some correpsondence to the cable #s and sequence numbers used
tonight when i get home i can give you my reverse telnet config on my 2511 and you
can match them with yours and i will give you correpsonding cable numbers

plus you have to make sure each host name corresponds correctly so first you need
to console cable to each device and set the host name first and then when you do your
reverse telnet config it will correspond as long as you match everything up

you will see once i give you my config

robert; been there done what you are experiencing but man will it be worth it!
i will not live with my 2511..and if it died i would pay what i need to get it back!
well worth it!

get rid of you ACLS for you access router
to troublehoot in the raw man just get rid of your ACLS on the interfaces tooo
and work with no ACLS period unplug your eithernet etc just use your
AR 2511 as an access router and once you get the bugs worked out you can add more
bells and whistles. i added and access group ACL for my telnet but that was once
i goot it all working.
toinght i will give my configs and cable numebrs
k!

do a "show line" on the 2511, you should see your 16 TTY lines there, if there is a "*" beside it, it means it's in use.

Issue a "clear line <line #>" to disconnect the connection, and try again.

ie. 2001 is your TTY line 1, if there is a "*", meaning it's in use, you won't be able to connect to that device. So to clear it, you issue "clear line 1"

ps. Just noticed you have a exec-timeout 0 0 for line 1 16, you might want to change that to 0 30 or something, otherwise if there is some problems with the TTY connections, you would always have to manually clear the connections.

hrmm config looks good, i had someone look at it....funny thing is
if i boot up the 2511 first i have no connection issues! hah
