    Hello All,

    I recently was asked to step in a figure out and correct this disasterous
    network that is the compilation of many long gone companies and cheap owners.

    I have narrowed some of it down but I will need a little help for some of
    the things that I am not familiar with. I got a learning curve here so if you
    can please be kind.

    There is a lot to accomplish but I do think this would be an excellent
    learning experience for many here from the pros.

    First, from inside the network on the Server 2000 Terninal server how do I
    access the main Cisco 1723 router?

    Lets start there.

    Sincere thanks ahead of time
    Joe

  2. Hello Joe,
    that's the kind of questions, where are the documentations and tools from
    the hardware maker of the router So you should sit down and take the time to
    study that.
    Ususally these things have either an own webserver or a command line based
    console. The last can either be reached with a kind of telnet client via LAN
    or via direct cable connection.
    For details for your router - you should be able to find and download the
    manual.
    Best greetings from Germany

  3. Hi Joe,

    If it has an ip assigned (as the main router it probably does), and
    depending on how configured the network is, it might be the gateway address,
    so you should be able to use the ip via your web browser to reach the
    router. If there is a password on the router that you dont know, this doc
    should help you...

    Hello Olaf,

    I have tried this.There is no manual for this that I can see. Everytime I
    try to get the manual from a link on a search engine it takes me to a Cisco
    private page that needs to have a password. Also there is two types of this
    same router.(which baffles me) One is the long green steel version and one is
    the smaller black plastic compact version. However I can try again to find
    out how.

    May I go beyond the routers now?

    Thanks
    Joe

    Hello Mr. Miller,

    Thanks for the help,

    Yes it has an IP however I cannot access it like this - I tried. IP's of
    this router are:

    External: 66.237.xxx.142
    Subnet is:255.255.255.248
    Gateway:66.236.xxx.201

    So the first uable address would be xxx.202 and it is. It is on the first
    NIC on the Server 2000 box along with 10.222.221.1.

    However I cannot access this router via the External IP nor from the xxx.201
    I can RDP into the server at IP 66.236.xxx.202

    There are other routers that are in the same way.

    Thanks
    Joe

  6. Sounds like abit of a mess youve got there. :)

    You can try using the Security Device Manager (SDM), "an intuitive,
    Web-based device management tool" for the Cisco 830 series through Cisco
    7301 routers, hopefully that will discover your router and allow you to
    manage it.

    Hello Coraleigh (cool name btw)

    Well you are right. There are more nooks an crannies here. I called the ISP
    today who provided the router and they had no trouble accesing the router.
    Now, this is how I got the IP's because they told me what they were.

    This network is functional but a disaster. To add to the mix there is a ppp
    to another building that I just got back up and running. Ok, Let's remove the
    accessing the routers because this might be trivial and then I can figure
    this out later.

    Ready for some mind twistin' netwoking here <grin> (I'm burnt)

    Ok, the primary server is a Server 2000 Box and the first NIC is dialed in
    like this.

    IP's 10.222.221.1 and in the advanced section added IP of 66.236.xxx.202
    Subnets:255.255.255.0 and in the advanced section added 255.255.255.248
    Gateways: 10.222.221.254 Metric 1 Now in the advanced section added gateways
    of 10.222.221.249 metric 1
    66.236.xxx.201 metric 1

    Second NIC on the same server
    Local Network Card 2

    IP: 10.222.221.99
    Subnet 255.255.255.0
    Gway:10.222.221.254

    Nothing more on this box.

    Now I know why they need the multipla gateways but I am unsure as to how
    they tied them in.

    I do not know at this time where the 10.222.221.249 is? Would this be a
    router?

    I know the others.


    The strange part is this. All PC's in the main building have the Default
    Gway set to 10.222.221.254 and this is a completely different router than the
    main router that I was referring to.

    The more I type the more I think this cannot be solved here. I hope not.

    I called the ISP again and told them to please come and do a " Tag and
    Locate" first.

    any feedback on this?

    Thanks
    Joe

  9. A tag and locate would be fantastic. :)

    Have you found any pcs using the 10.222.221.249 gateway, outta curiosity?

    I would think that this would be another router configured perhaps to assist
    in load balancing (since they both use Metric 1) your internal traffic, with
    the 10.222.221.254. But if you cannot physically find another router which
    could be it, then its possible they used a server or desktop for it.

    Good luck!!

    Hi Coraleigh

    Well, no, This is why I do not know where it is. No PC or router that I know
    of used or uses this gateway.

    In the other building there is a better setup but it ties into this main
    buiding that is a mess.

    In the closet room is another Cisco steel version rack mount that has to be
    a Default gateway of 10.222.223.1
    All PC's in this buiding have this gateway. (Still cannot access this router
    either)

    This particular building is not what I am so concerned about because
    actually it is "cut and dry"
    a bunch of PC's and a set of drops in the walls and the main router with
    managed switches mounted with the router.

    This is what I am thinking....

    The afore mentioned building with the 10.222.223.1 tidy setup is set on a
    PPP to the main building through BellSouth CO (Central Office) and into
    another Cisco 1700 steel rack mount. Wala! I think this is the 10.249 because
    you wouldn't need it on a PC or server. Just for a connection as a default
    gateway to access the other routers and PC's.(it seems)

    Thoughts???

    Thanks Coraleigh

  11. Dont know why I didnt think of this before...try to telnet to the
    10.222.221.249 to see if you get a response. If you are able to login to it
    then use the netsh tech command and we should get some info on this router.

    It sounds to me thus far that you could be correct about this router.

    Hi Coraleigh,

    Thanks good advice? Let me give it a shot and see. Can you give me a full
    command line as I am unfamiliar with this?

    As an aside I thought that line way back was moving. I am a girl :)
    sorry for being so....presumptuous <blush> I raised my daughter by myself as
    a single parent so I now about girls.( I think)

    Thanks for the input it is truly helping me.

    Hello Coraleigh,

    Ok! Got a username and password prompt. I did it like this.

    Start>>Run>> CMD Typed telnet 10.222.221.249 and I got a user access prompt
    in the command line screen.
    I don't know the passwords but I think I can get them.
    I am going to try the other router and report back :)


    Thanks

    Hello Coraleigh,

    Well I am able to telnet to all routers even the external main router. All
    ask for a password which I do not know.
    What would I see after I enter the telnet method of accessing the router?

    Thanks again
    Joe

  15. Hi Joe,

    After you login with a password you will get to type in Cisco IOS commands
    such as
    show tech-support
    (umm yeah i forgot the last bit of that command before -i got it right this
    time, sorry been awhile since ive been on Cisco) :)

    Here is a good list of the Cisco commands you can use while telneted in...
    http://www.thenetworkadministrator.com/ciscoroutertips.htm
    These should help us get some great info on your mystery routers.

  16. We should drop all that info to a file as well to make it easier to see
    since there will be alot of it, use the command
    show tech-support | redirect tftp://10.10.10.10/bigrouter.txt
    change the ip to a server you wish to store your text file to obviously
    though. :)

    Ok Let me clarify

    Once inside the router. Issue the command

    show tech-support | redirect tftp://10.10.10.10/bigrouter.txt

    Replace the IP in this command to a server or location in which I can get
    the text file and read it. Correct?

    What is tftp ?
    Thanks Coraleigh
    Joe
     
    Joe, Jul 21, 2007

  18. Tftp server is is a simple file transfer protocol, with the functionality of
    a very basic form of FTP.
    http://en.wikipedia.org/wiki/Trivial_File_Transfer_Protocol

    Usually if there are a number of Cisco routers in an envirnment there is a
    tftp server nearby, but since you're fairly new to this company's network
    and since its a mess..well who knows if there is one. Sorry my fault for
    assuming. :) Somtimes I overlook the simpler approach to things, which in
    getting a router info file output would be to copy and paste from your dos
    screen. Since there will be alot of data, you should first increase your
    dos buffer size. To do this open your dos app, right click on the top left
    corner (in the title bar) and select properties, in the Buffer Size box set
    the number to 999 and click ok. When you later have a screen full of router
    info you can right click on the top left corner again and select edit->
    select all and then edit -> copy . From there you can simply paste into a
    text doc.

    Once you are inside the router issue the command:

    show tech-support


    You arent at work today are you?? I hope you enjoy some of your weekend.

    Hello Coraleigh,

    Thanks for the info and learning me something new today. Always a plus!

    No, I am not at work but, I wanted to get a heads up on this situation and I
    won't be able to get back to this disaster until about Tuesday or Wednesday
    night. But in the meantime I can gather as much info from here as possible.

    This network is not even in a rack. It is layed all over the place with
    wires EVERYWHERE! Whooo...

    I have to find that to ....a rack

    Thanks for asking :) I am going out for a while. It's Saturday and I need a
    break. I will monitor this thread.

    Thanks a bunch

    Hi Coraleigh,

    Do you know of any network discovery tools. Inexpensive or free?

    I have gotten really far from the last post. But this kind of tool will fill
    in the gaps.

    Thank you
    Joe
