RV110W telnet problems
I have Comcast Business internet, an SMC modem in "passthru" connected to the RV110W which in turn connects to my network. I have one server on the network that I want to telnet to. I have set-up port forwarding port 23 to 192.168.1.xx (server). On the internal LAN if I use a command prompt and telnet to the server, every thing is fine. If I try to access the server from a remote, It won't connect on port 23." could not open connection to the host on port 23". Where am I going wrong. I need the router because I have one static IP. On my old DSL connection everything was fine but I needed to switch because of mail server problems.
I have just created my login, and the other logins worked fine earlier. Nothing has been changed on the machine that I am aware of and a comprimise is highly unlikely in this situation. All logins freeze at the same place on the telnet login. Would it be possible that I need to create the user with admin rights? If so, how?
Also, The server is running a service of which I cannot break to shell ( chances are I just don't know how yet). Since I an in the application console, could that be a cause?
Thank you

ASA5520 reverse telnet problem
Hi all,
I have a problem with ASA5520 and reverse telnet. I recently upgrade IOS on ASA5520, asa921-k8. Problem is that cisco has latest IOS version asa91x.... for this platform.
I have 7201 on remote site, and connect his aux to asa console. When I do telnet to specific port, this is output:

This is run over and over. I just can't enter a ROMMON mode of ASA. I have older IOS on flash which works.
I don't know what to type to enter in rommon mode. I tried every combinatios of characters but nothing. I used Putty, SecureCRT.
Any idea?
Regards,
NenadSo ESC isn't working during boot? FYI 9.2 is not supported on non-X ASA chassis (which I'm sure you have now figured out). You can also try changing the escape sequence so ESC will work. Check this link on how to change that.

Hello.
I have Cisco Router 876 Series, and have problem with telnet. i cant connect via telnet from remote office to my router. does anybody know how to solve that problem.
I have two vlan, vlan 1 is a nativ vlan and it is config for inside network, and vlan 2 for outside.
and fa0, fa1, and fa2 interface is in vlan1, while fa3 is in vlan2.
Anybody please!!you stated you have it configured for ssh. does ssh work? i would suggest using that anyway. perhaps you have it only configured to use telnet from inside not outside aswell.
you will need something like this
telnet 10.1.2.0 255.255.255.0 outside
regardless of what you have in acl if you dont apply telnet to ouside it just wont work.

Hi guys,
Okay so i have 4 cisco switches 3500 and 1 3750E(core switch) on a subnet like 10.1.7.* configured for telnet. Between them telnet works but when i try to access them from a different subnet it doesnt work and i used the ip default gateway command set up my gateway.Im thinking the problem is with the router witch is not a cisco one its a pfsense.Any ideas? Thanks. i dont really have access to the router but there shouldn't be a rule that is denying this
dunno about the routing protocols or if its needed some networks to be added.
Best Regards,
CristianHi,
It sounds very much like a route is missing, either on the host with the telnet client which is missing a route to the 10.1.7.x network via the correct gateway, or the routing table on the pfsense doesnt know about one of networks.
Check the routing tables on all devices end to end and make sure they know about both the source and destination networks.
You can also try a tracert if its a windows box and see how far the trace gets.
Hope this helps.

Good Morning,
i have a question for the community :)
My configuration:
Modem router Telecom for WAN connection (192.168.1.1)
Cisco RV110 (192.168.1.100) for manage 2 local LAN with different class (192.168.2.x and 192.168.5.x) that can not communicate each other.
The request is NAT a port for an Ip address on VLan (2.x)
I had configured the Telecom Router with this rule (TCP EXT 82 -> TCP INT 82 to IP 192.168.1.100 "cisco"), after i created a rule on Cisco (TCP EXT 82 -> INT 80 to 192.168.2.10).
The packet arrive with destination (i checked with wireshirk) but on different port for example:
91.252.189.137 192.168.2.105 TCP 74 [TCP Retransmission] 22080→84 [SYN] Seq=0 Win=14000 Len=0 MSS=1380 SACK_PERM=1 TSval=1259661 TSecr=0 WS=32
Why the port are different.I find the problem, the RV110 not support the NAT Traversal :(
That's why the port are wrong. -
866VAE-K9 Modem/AUX and rev. telnet Problem
Hi Everyone,
I am currently observing some strange behavior of 866VAE-K9 router which might be a bug or my mistake, so I would very much appreciate your suggestions...
The 866VAE-K9 router has a single physical AUX/CON port.
The documentation states that in order to use AUX with a modem
one has to:
line con 0
modem enable
If I do this, some process starts on the line 1 and prevents
using of chat scripts and reverse telnet:
start-chat Dialout1 aux 0
% Chat script can not be run on line running other process
telnet 192.168.10.1 2001
Trying 192.168.10.1, 2001 ...
% Connection refused by remote host
If I clear line 1, and immediately after that start a chat script,
then it works (telnet hangs on at "asserting DTR"), but if I wait for
several seconds the line 1 becomes busy again...
Your suggestions/ideas are very appreciated!

We're running LMS 3.1. Whenever I try to telnet to any device I get a message "Application Not Found". What application is it trying to open and how do I change it?
I assume you mean from Device Center? If so, then you need a telnet.exe on the server. You may need to follow http://forums.vandyke.com/archive/index.php/t-2074.html (or something similar) to make sure the telnet:// URL is handled properly.

Telnet to Internal Device with single Global Address
I'm managing a field office that connects to the internet through an ASA5505. This office has only a single external address (static), but I have a device on the inside of that network that needs to be accessed by a vendor via telnet.
Could anyone suggest a good way to accomplish this?
Thanks,
ChrisA shot in the dark guess (so take it with a grain of salt):
I wonder if you might be hitting a "by design" Telnet problem. I've seen a couple of references to "the firewall will not permit inbound Telnet connections on its outside interface even if the config allows it"
The Cisco Press "Cisco ASA and PIX Firewall Handbook" mentions it as do a couple of results that pop up in a Google search of: cisco pix telnet outside
Since you're Telnetting in on the outside interface and your destination address is within the firewall, perhaps it's being silently disallowed. ?Just a guess?
Is there any possibility the outside vendor (and your inside device) can use SSH to communicate? I know *that* works just fine on the outside interface when redirected into a tunnel. -

Cisco ACS command authorization sets
I need help on the following please.
1. - I am using ACS as TACACS server to control IOS authorization on all our Switches, However I can not deny telnet sessions to other devices from within CatOS - does anyone know the command authorization set to deny this within ACS ????
2. Does anyone know where I can read up on command authorizations sets for ACS ??
3. What is the debug command for CatOS to see cli output ?
Many thanks
RodThanks for your info. I have solved my problem -
1. I enabled tacacs administration logging using command on switch aaa authorization commands 15 default group tacacs+
This let me see what what happening everytime I entered a command on CatOS - via the logging monitor on ACS. From here i was able to see that when i was trying to telnet to a device from CatOS it was doing it on Privilage mode 1. I then entered this command aaa authorization commands 1 default group tacacs+ which solved my telnet problem.
Problem resolved.
Many thanks. -
Hi,
I have been assigned the task of fixing a Solaris system on Intel platform.
There are two problems that I fugured out. The root filesystem is 100% full.
And number two I am unable to connect via telnet to the server from any other PC.
Could anyone tell me, how do I extend the root file system and what all things I need to do so that telnet can be used to connect to the server from other PCs.
Thanks a lot
AmitavaPerhaps you should first try to find out why the root
filesystem is 100% full. Sometimes someone mistypes a
tape device name while performing a backup and the whole
backup is written as a huge file into the root filesystem;
or some server/daemon has produced huge amounts of log file
entries (or other things like that).
Run something like "find / -xdev -type f -size +5000 -ls"
and check the resulting list. The command searches for
plain files > 5000 blocks (> 2.5Mbytes). Maybe you can
identify some files that need cleaning / can be deleted.
Sometimes you cannot identify files using up disk space
using a find command like the one given above,
because the file is already deleted from the filesystem,
but some process still keeps a reference to that deleted
file. The kernel cannot free the file's data until
that process closes the last reference to the file.
You can identify processes that keep references to
big, deleted files using a different find command:
"find /proc/*/fd -type f -size +5000 -links 0 -ls".
This searches the machine's process "filesystem"
for processes with file descriptors that have no links
in the filesystem (-links 0), and that are plain files
(-type f) bigger than >2.5Mbytes (-size +5000).
If this second find command produces any output:
The number between /proc/ and /fd/ is the pid of a process,
the number after /fd/ is the file descriptor number
inside that process. You can free the file system space
by stopping / restarting that process/daemon.
For the telnet problem: How long did you wait for a
server prompt? Wait at least a minute or two. If the
server prompt appears after a long delay, the typical
problem is that the server tries to look up the hostname
for the client connecting to it, and the name service
(DNS?) is slow or does not respond. The hostname lookup
eventually times out (after 60 seconds for example) and the
telnet prompt appears. This can be fixed by making sure
that the server gets name service responses for each
pc connecting to it. -
Hola tengo un problema que me gustaría solucionar:
Tengo instalado un router EPC3825 y quiero crear una VPN entre este y otro rv110w, el problema es que entre uno y otro hay un router de telefónica necesario para la configuración de red.
Mi pregunta es que debería hacer con el router intermedio, como deberia configurarlo etc.
Muchas gracias.Hi
I'm working on the same problem.
I have Routers with a L2L VPN for management and clients behind the router establishing VPN to central site.
Sometimes the management VPN gets lost and if I take a look to "sh ip nat trans" I can see that there are two nat translations:
(roIP=router outside IP, cLIP=client LAN IP, csVPNg=central site VPN gateway)
Pro Inside global Inside local Outside local Outside global
udp roIP:500 cLIP:500 csVPNg:500 csVPNg:500
udp roIP:4500 cLIP:4500 csVPNg:4500 csVPNg:4500
This naturally collides with the routers management VPN connection from roIP:500 to csVPNg:500.
Astonishing is that it works for a certain time.
Until now I didn't find a solution.
The only thing I have in mind is to change the routers VPN to another UDP-Port or TCP.
But maybe there's an easier solution?
