TCL scripted probes on ACE

Hi,
I have two questions about TCP scripts on ACE :
1. TCP source code
How can I browse the TCL source code of predefined probe scripts on the ACE (for instance HTTPCONTENT_PROBE) '
2. Script parameters
How do I retrieve in the TCL script the parameters passed to the script in the command < script script_name [script_arguments] >  ?
Thank you,
Yves

Yves,
you can download all the scripts from the download software page.

  • Simultaneous tcl script probes on csm-s

    Hi there,
    is there anybody who kows how many simultaneous tcl script probes can run on the csm-s ?
    I know that i can only open 255 simultaneous sockets. when i have one connection(open socket) per script, there should be only 255 probes that can be run Simultaneously.
    is that right ?
    Thanks a lott.
    Bye Dirk

  • ACE TCL Script Probe for Websphere MQ

    Have anyone written a TCL script to probe MQ from the ACE?  Our app guys are saying that a Layer 4 probe (TCP port check) is generating errors in the QManager logs because there is no data exchange, just TCP connection setup, then tear-down.
    Thought I would check here to see if anyone has written a TCL Script for this before or has any other suggestions.
    Thanks!                  

    Hi,
    What do you need to check exactly on the server?  will be an specific uri?

  • Looking for ACE Probe TCL script specific for LDAPS

    Hello Everyone,
    I have searched the forum, and i am having difficulty finding an example of how to modify the LDAP TCL probe from port 389 to secure LDAP port 636.
    Could someone kindly point me or provide me the modified TCL script if you happen to have it.
    During my search I also found a config that someone had provided, which contained the following probe:
    probe tcp LDAPS_Probe
      port 636
    probe tcp LDAP_Probe
      port 389
    I was trying to figure out if this a modified TCL script for LDAP or modifed TCP TCL script specific for port 636.
    This is how I applied the script for LDAP port 389.
    script file 1 LDAP_PROBE
    probe scripted LDAP_PROBE_389
    interval 5
    passdetect interval 30
    receive 5
    script LDAP_PROBE
    serverfarm host SF-LDAP-389
    description SF LDAP Port 389
    predictor leastconns
    probe LDAP_PROBE_389
    rserver LDAP-RS1-389
    inservice
    I will be more than glad to provide you any additional information that you need.
    As always thanks for your input.

    normally you would engage a TCL developer or ciso advanced services to develop a custom script for anything other than what Cisco provides in canned scripts. If you are comfortable with tcl you can do it yourself. Here is an example of the LDAP script modified to include initiation via ssl.  default port is 389 when you implement you would specify 636.
    #!name = LDAP_PROBE
    # Description:
    #    LDAP_PROBE opens a TCP connection to an LDAP server, sends a bind request. and
    #    determines whether the bind request succeeds.  LDAP_PROBE then closes the
    #    connection with a TCP RST.
    #    If a port is specified in the "probe scripted" configuration, the script probes
    #     each suspect on that port. If no port is specified, the default LDAP port 389
    #     is used.
    # Success:
    #   The script succeeds if the server returns a bind response indicating success
    #    (status code 0x0a0100) to the bind request.
    #   The script closes the TCP connection with a RST following a successful attempt.
    # Failure:
    #   The script fails due to timeout if the response is not returned.  This
    #    includes a failure to receive ARP resolution, a failure to create a TCP connection
    #    to the port, or a failure to return a response to the LDAP bind request.
    #   The script also fails if the server bind response does not indicate success.
    #    This specific error returns the 30002 error code.
    #   The script closes any attempted TCP connection, successful or not, with a RST.
    #  PLEASE NOTE:  This script expects the server LDAP bind response to specify length
    #   in ASN.1 short definite form.  Responses using other length forms (e.g., long
    #   definite length form) will require script modification to achieve success.
    # SCRIPT version: 1.0       April 1, 2008
    # Parameters:
    #   [DEBUG]
    #      username - user login name
    #      password - password

  • ACE probe TCL script database

    Hello everyone, okay?
    I was thinking of a possibility to use my ACE to monitor a database, in this case a MySQL database Today I use a TCP probe, monitoring the port, but I would go one step further and try to make a connection in the DATABASE.
    I would like to see the possibility of a guideline in creating a TCL script to make a simple connection to a database.
    The idea is to try to make a connection in a database, run a query / select on any table just to validate its functionality and not just checking if the port is responding.
    I do not know how complex it is or what would be my pre -requisites required, but any help would be welcome.
    I thought about using an HTTP probe to make this validation and use a web page making the connection to the database, but it ended up creating another layer and if there is any problem in web service, the database would be affected indirectly.
    Thank you. All suggestions are welcome.

    Hi Plinio,
    I cannot see any support for testing authentication, SQL queries or connections to a database that is supported directly in TCL at this time.
    Here is the TCL guide that expalains the supported commands ( there is a HTTP example probe at the bottom )
    http://www.cisco.com/en/US/docs/app_ntwk_services/data_center_app_services/ace_appliances/vA4_2_0/configuration/slb/guide/script.html
    Beyond a TCL TCP probe to the port to test the listener is running, I believe your suggestion of a HTTP TCL script is probably the most accurate way to check the integrity of the database. You could write code to set a certain response to all types of failure scenarios and on the ACE you could then use a HTTP TCL script to parse the response from the web server to identify exactly what has failed in your database and act accordingly.
    cheers,
    Chris

  • ACE TCL Script to retrieve Cookie

    I am in need to to do a post instead of a Get with a probe. So I have configured a TCL script to perform this. The issue I have is that I also need to parse the Cookie instead of the http1. response. Any ideas? Or does anyone have a variable indetifiers for TCL scripting that Cisco uses?
    Thank you,

    HI Thulin,
    Health probe scripts have access to many configured items through a predefined TCL array. The most common use of this array is to find the current real server IP addresses of the suspect during any particular launch of the script.
    Whenever the ACE executes a script probe, a special array called scriptprobe_env is passed to the script. This array holds important parameters that may be used by the script.
    Member name Content
    realIP
    Suspect IP address
    realPort
    Suspect IP port
    intervalTimeout
    Configured probe interval in seconds
    openTimeout
    Configured socket open timeout for this probe (tbd)
    recvTimeout
    Configured socket receive timeout for this probe
    failedTimeout
    Configure failed timeout
    retries
    Configured retry count
    healthStatus
    Current suspect health status
    contextID
    The ID for the context running this script
    failedRetries
    Consecutive successful retries on a failed server before marking it as passed
    isRouted
    Boolean to determine if this IP address is a routed address
    pid
    Process identifier of the TCL process
    runID

  • Use of gset in CSM TCL Script

    Hello,
    I am trying to write a TCL script on a CSM (Code Ver 4.1) that retains the value of a variable between probe instances (so I can increment and check a variable in each probe attempt). Looking at the documentation there is supposed to be a 'gset' command that does this but cannot make this work.
    The example says 'gset var 1 ; incr var'.
    I have several problems with this:
    1. I would think that this would set the value of var to 1 each time it runs and then increment it (maybe)
    2. How can I read the value of the persistent variable without it causing an error if it doesn't exist?
    3. It doesn't seem to work anyway as var doesn't appear in the Persistent Variables section of 'show mod csm x tech script'
    Any ideas on this or on where I can get some examples where the gset command is used?
    Many Thanks
    LP

    it works for me:
    I just added the gset and incr commands to the echo probe and it I do see the counter increasing.
    gset counter 1
    # parse cmd line args and initialize variables
    puts "initializing variable 2"

  • Cannot generate IP using TCL script

    I'm trying to pull in a customized PCIe block from a .xci file using my TCL script with Vivado 2015.2 on Ubuntu 12.04.  I then want to generate all the IP output products and run through the entire design flow (to eventually generate a bitfile).  When I try to call create_fileset on my PCIe IP, I get the following error:

  • Cisco's Network Registrar and LDAP (tcl script)

    Hi all,
    I use CNR version 7.1. I use ldap for authentication user. I have a problem if ldap server not available. I want with tcl script to know what ldap not available and send to user default configuration (ip,dns) 
    How I can transfer in tcl a script that the server ldap isn't accessible? where i can found error code for this ?
    Thanks
    Roman

    Hi Habeel,
    I've answered this question before. If you search the forum for "ldap healtcheck script" - and yes the typo is real then you'll see what I did.
    The text is here:
    The easiest way is to capture a packet with the authentication credentials and then replace the hex bind string in the example.
    The alternative is to handcode the BER coded ASN.1 data string - which while more fun is time consuming. The remainder of the script can stay the same.
    I've done this on an ACE module. You have to be aware that 300c02010160 in the example script string is a sort of "header" that holds the request id (1). This will be different in your packet capture.
    If you look at the decomposition of the example you'll be able to see how it is put together and what you need to change.
    0x30 The start of a universal constructed sequence
    0x0c The length of the sequence minus the tag and length bytes = 12 bytes
    0x02 Next field is an integer
    0x01 The length of the next field (1 byte)
    0x01 Value (this is the message ID)
    0x60 Application, number 0, use RFC2251 to decode. This is a Bind Request
    0x07 Length of data to follow.

    where I've replaced the 9 character password with 9*x'ff'.
    The username for binding is AceProxy. If you want to use the same script then create that username and set the password in the string above (in hex). If for example you set the password to Example12 then you need to set the 9*x'ff' to '4578616d706c653132' - which is the hex representation of the ASCII.
    Note that if you use fewer or more than 9 characters then you'll need to change other values in the string because they refer to lengths.

  • Custom tcl scripts

    Hello,
    For one of my customer, I have to write two csm probes:
    - One that connects on tcp port 6200, sends the following message "test\\n" and verifies that the answer is "UP"
    - Another that checks if ICAP is working or not. To test this, I need to write a probe that makes an "OPTION" ICAP request.
    Is it something possible ? If yes, where can I find some guidelines.
    Thanks

    simply go to the CSM software download page and get the TCL scripts file (*.tcl)
    Edit the file and should have many examples to use. For your probe #1, you could reuse the echo_probe that sends a line and check the response from the server.
    For the 2nd probe, you should probably get more info on how the "option" request works and what response to expect.
    This is however definitely possible to do.

    Network Scenario:
    We have a Client-Server enterprise network, and nature of servers is to broadcast some stats/info to all the clients.
    We are using two 6509-E at core with HSRP to provide the redundancy for servers. I have attached the network layout (not the real one) with some description with this thread. On both switches we have configured “ip helper-addresses” to forward the broadcast to multiple destinations(different VLANs). Every thing is working fine with respect to HSRP.
    Problem:
    Under normal circumstances, both ACTIVE and STANDBY hsrp switches generates broadcast which causing duplication of every broadcast packet and Client end receiving every packet twice. Cisco already claimed that standby switch will forward the broadcast. As an alternate TAC has advised to use the TCL script as a work around which we attempted to however no success at the end.
    Please let me know if some one can help me in modifying TCL script.

    Try this version.  You will need to first set an environment variable, dhcp_servers to be a comma separated list of IP addresses (i.e. the helper addresses) to configure/unconfigure.  For example:
    event manager environment dhcp_servers 192.168.10.255,192.168.12.255,192.168.14.255

  • Creating a job that runs a Tcl script

    Hi,
    We currently have a scheduled job running a Tcl script on a 8.1.7 DB. My question is, can I still use the same setup in 10g DB (i.e. creating a job that runs Tcl script)? If I can, how am I gonna do it?
    Thanks,
    howie

    It depends on how you scheduled the job in 8.1.7 DB.
    By Cronjob? Yes you can do the same to connect to 10g
    By DBMS_JOB?. Yes you can do it in 10g and in addition, can improve it with DBMS_SCHEDULER
    Via OEM? Yes in can use Enterprise Manager to create a Job that runs the Script.

  • Setting the source-interface in a tcl script for email.

    So once again I am trying to figure this out and failing miserably. The only thin I can think of at the moment is that I need to tell it to source from a specific vrf interface. I've tried looking through possible enviornment variables. Hoping I could set it that way but have yet to find one. I have read varios settings for source-interface and attempted them. But fail every time with:

    eem-gold: (rel1)1.0.2
    eem-call-home: (rel2)1.0.0
    Below is the stock format for sending the email from the script. If someone could guide me in the correct way to set this up to source the interface that would be awesome.

    I got this far, saw the MAXRUN error, bumped that out and then turned on debugging. I am still not connecting to the mail server. So I don't think I am reaching the mail server yet. I don't think it is using the sourceinterface. In debugging everyting in the script works except for the mail portion.
