SimpleAgentPro (SAPro)/SimpleAgentEnterprise (SAEnt) Release Notes
SimpleSoft is pleased to announce the following new releases of its SimpleAgentPro product.
SimpleAgentPro/SimpleAgentEnterprise Ver 18.5 Release Notes
December 16, 2014
Simulated devices can now also support Netconf over SSH within SAPro/SAEnt. It works in conjunction with the modified opensshd server configured to listen to Netconf port 830. This feature is currently available in the Linux version only. The Netconf simulator uses a telnet style modeling file approach for simulation.
A proxy based learning mode is supported where in requests from the management application come to the simulated device which simply forwards the request to a real Netconf server. The simulated device then sends the responses received from the real Netconf server back to the management application and creates debug files that record both request/responses.
A new ncdconv utility is also provided which converts the debug files created in the proxy mode into a netconf modeling file that can later be used for simulation without the need to have a connection to a real Netconf server.
Flag Action support for coordinated execution:
%flag_action section is now added to the modeling file syntax to allow for evaluation of tcl scripts in device context upon receiving a TCP message. The SAPro/SAEnt GUI, the sapcnsl command line utility as well as Tcl commands like SA_setflagactionid can be used to trigger this action.
This section is useful in triggering script execution in a specific device, in all devices in a specific map, and in all devices in all running maps.
Topology Editor:
An option to load the generated map into the current workspace in SAPro/SAEnt is now provided.
A command line flag is now added to disable the redundant link limit checks.
Users can now specify the base directory for the generated project. The default directory of "../projects" is not changed.
Generated maps are now automaticaly optimized and broken up into multiple maps.
Sapcnsl has been enhanced to support retrieval of cable performance statistics using the cablestats command.
Sapcnsl also supports SNMP performance statistics retrieval if the THRESH_RESPTIME option is specified in the config.inp file.
Sapcnsl can now also be used to trigger flag action for all maps, specific map or a specific device in a map.
Sathrd/Tcl Commands:
Tcl Command to enable wildcard pattern matching in XML based request/response files is now supported.
VMware vSphere API support:
Updated support for OpenInventoryViewFolder commands when used in filters.

Support for new pcapng file format added to sapt2tel, stpktcnv, supktcnv, sapp2dat, and sapp2var utilities.
Added generation of additional SNMP topology related columns and rows for LLP support to topology wizard and editor.
SimpleAgentPro/SimpleAgentEnterprise Ver 18.0 Release Notes
July 15, 2014
The sapt2tel utility has been enhanced to decipher tcp packets from a regular pcap file and create a telnet modeling file. You can now use wireshark/tcpdump to capture telnet interaction between your application and the real device and then provide the pcap file to sapt2tel and it will create a telnet modeling file that can be used for simulation.
A new SSH client learner utility is now available that can take a list of commands to send to a real device and convert the responses to a telnet/ssh modeling file.

SimpleAgentPro Ver 11.5 Release Notes
July 10, 2008
Telnet learning command line utility:
tellearn is a command line utility that given a list of commands to learn and device profile, will setup up a telnet connection and convert the telnet responses to a telnet modeling file.
The utility to convert captured telnet session text files to telnet modeling files is now called sapt2tel.
Support for Wild carding in telnet commands:
There are many commands that seem to have only one parameter different, and the responses are also same or differ with regards to that parameter. By allowingwild carding in commands, it is possible to reduce the number of commands in the modeling file, thus reducing the device footprint.
Pre-compilation of telnet/snmp modeling files:
Modpcomp is a command line utility that preprocesses modeling files. It handles both telnet and snmp modeling files. When a script is written to learn all the CLI commands supported by the box, then the modeling file can become as large as 2G bytes. For large modeling files, if they are precompiled, then the time required to start a device/map can be significantly reduced. The telnet/snmp modeling files can also be encrypted prior to distribution.
Dynamic addition of telnet command actions:
Running a telnet command sometimes can result in the device supporting additional commands as in the case of provisioning. To allow this a new tcl command SA_telnet_addcmdaction has been added to the telnet Tcl interpretor.
Support for tftp client commands in telnet session.
To allow the tftp client tcl commands to also be interpreted in a telnet session, a new tcl command has been added that enables the SA_tftpget/SA_tftput commands, called SA_telnet_addtftpclientcmds.
Timestamps in syslog:
Today syslog events are treated as a simple string. New Tcl functions called SA_getsyslogtstamp and SA_getsyslogheader that returns the timestamp in sylog format have been added to allow its embedding in the syslog string.
Router cloning with multiple interfaces:
Today SAPro allows substitution of the primary management interface with the use of tokens. But if the device has additional IP addresses, then those do not get autoincremented during cloning. To solve this issue, support has been added to use tokens for the additional interfaces also.
HTTP root directory cloning:
Today SAPro allows you to specify different root directories for different devices, so that each device can have a separate index.html file. If the http root directory of a device has its own IP addresss as part of the directory name, like "/http/", then if that device is cloned, the root directories for the cloned devices will automatically be set to
"/http/" and
"/http/" etc.....
The actual directories and the different index.html files would need to be setup manually by the user, but the map generation part will be automated.
Support for command line learning of traps/syslog:
saptrlrn is a command line utility that opens up trap and syslog ports and listens for incoming traps/syslog events. Upon receiving them, it will convert them into corresponding tcl commands for trap/syslog generation. Typing a CtrlC terminates the running application.
Map cloning:
A map can now be cloned. The IP addresses of the devices in the original map are incremented by incrementing their subnets. Associated mac addresses, and topology data fields are also auto incremented. An option is available to add the new devices to the same map or to create new maps.
Telnet Statistics:
The Device and Map statistics now includes an option to also see Telnet statistics. Number of telnet sessions and number of CLI commands processed are counted and displayed.
Topology Editor supports additional interface types:
Topology editor now allows you to select the interface type for the interfaces instead of just ethernet(6) The different interface types are present in an editable, and user expandable list.
Topology Editor supports tokens:
Topology editor now allows you to create variable files with tokens instead of actual values, so that the configuration can be cloned with the new Map Cloning feature.
Workspaces with separate directories:
Workspaces can now be created so that they have their own subdirectories underneath the sapro/projects directory. The newly created files can all be contained underneath one root directory.
Tcl command to enable Variable Marking:
The SA_dumpgotvars command can be used to dump out all the variables that have been accessed by a manager since startup. It used to be controlled by the MARKVARSREAD = YES flag in the config.inp file. Enabling it would cause all devices to keep track of the variables being accessed. A new tcl command called SA_setmarkvarsflag has been added that allows this behavior to be controlled on a per device basis.
Sappoll to try SNMPv1 if no response received with SNMPv2c:
Sappoll has been enhanced to automatically try using SNMPv1 if no response is received from an agent by sending it a SNMPv2c request. Most of the command line arguments are also echoed in the output.
SNMP Request generation utility:
Saprqgen command line utility processes the snmp debug output and uses it as a basis to recreate the manager requests to be sent to the device. It extracts the SNMP request pdus and then recreates new requests that are similar to the original requests received by the simulated device. The command line argument allow you to overwrite the information in the request packet captured in the snmp debug file.
Telnet request regeneration:
A new debug level has been added to SA_telnet_debugflag. Setting it to 9, makes SAPro only write out the commands received. The debug file with these commands can then be given to the tellearn utility to recreate telnet commands received by the the simulator.
Stop status reflected on the GUI:
In the past, the GUI would show that all the maps have stopped, even though the maps were being stopped and cleaned up. The GUI now reflects the current status of the map/device cleanup more closely, when the WAITFORDEVICESTOSTOP=YES is enabled in the config.inp file.
Patching of timestamps in pre-created trap pdus:
To get better trap generation performance, users could create the trap pdu before hand in the init_action section via SA_trapgetpdu, and then simply send the generated packet in the timeraction using SA_sendtrappdu. But this trap packet would be the same every time and would not reflect the changing value of sysUptime. An optional second argument has been added to the SA_sendtrappdu call, that if set would cause the SAPro to partially decode the pdu and then patch the sysUptime value in SNMPv1, v2c and v3 (noAuth/noPriv) packets.
Token processing optimization:
Previously, when tokens were used in var files and they were part of table with very large number of rows, the time required to start devices and process get-next requests would be very large. The token substitution process has been optimized for better performance.
Tcl version upgrade:
The Tcl interpretor has been updated from Tcl 8.3 to Tcl 8.4.18 It will inherit all the updates and changes made to Tcl since Tcl 8.3
Bug Fixes/Minor Changes:
TFTP client software would loop on receiving an ICMP error when trying to connect to a Windows 2003 server which did not have the TFTP service running.
SAtcmd() variables were not getting cleared.
Line numbers used in error messages by sapw2var were not correct.
Sapvsort did not handle %csibegin sections correctly.
Telnet debug file name did not allow creation in different directory.
