When the GUI is restarted, it can connect with already running maps and be able to get updated status for them as long as they are in the GUI's workspace.
This is particularly useful when the terminal used to start the GUI is inadvertently closed or forced to be closed, causing all the simulations to stop.
Maps started externally by sapcnsl can be seen by the GUI when the "Update Running Maps" popup menu is chosen.
Support has been added for two additional tokens $$MYIPSUBNIDS$$ and $$MYIPSUBNHEX$$ that are based on the IP address of the simulated device. If the simulated device IP is, then the value of the first token will be 10.5.1 and the value of the second token will be 0x0a0501.
The rules file syntax used by sapw2var to convert walk files to var files has been enhanced to include special tokens like fixed($lc$) and fixed($fc$) inside the valuetype to take the last characters to the value of the variable retrieved in the walk or the first characters, instead of just fixed(%s) as was supported in the past.
The rules file syntax used by sapw2var to convert walk files to var files has also been enhanced to include %appendbefore, %appendafter and %tclscript to allow insertion of variables not present in the walk file, and manipulation of the value via script based logic.
When creating var files from pcap files, sapp2var has been enhanced to treat variable bindings inside SET requests as RW variables.
SAPro GUI now allows multiple trap managers to be specified in the trap generation dialog.
Sapt2tel has been enhanced to be more similar to tellearn in the output created.

Default server.pem and skey.pem have been updated for SSH2.
SimpleAgentPro/SimpleAgentEnterprise Ver 19.0 Release Notes
June 30, 2015
Telnet responses from a real device can now be learnt and converted to a telnet modelding file by simulating a proxy device that forwards application requests to a configured real device. It then returns the responses from the real device back to the application and creates a debug file that contains the requests and responses. This debug file can then be converted to a telnet modeling file. When the list of telnet commands sent by the application is not known before hand, the proxy can be used to do recording.
The telnet learner program has been enhanced to support command completion response based learning. Three additional keywords %CMDCOMP%, %RCMDCOMP% and %TCMDCOMP% allow the substitution of command completion response to facilitate learning. A recursive mode as well as tcl variable mode is supported.
The telnet simulator now includes built-in support for netconf queries to support "netconf echo" style IOS commands. A new %netconf_cmd_action keyword is added to the telnet modeling file and it allows the generation of netconf responses. The special netconf terminator of "]]>]]>" is used to demark the end of netconf queries.
The sapt2tel command line utility has been enhanced to also process netconf request and responses. It looks for the "netconf echo" style IOS command for special processing.
SA_snmptcpopen and SA_snmptcpclose tcl commands have been added to the device tcl interpretor to allow handling of SNMP requests over TCP in addition to the standard UDP port. The specified TCP port is opened and the simulator waits to receive connections on it and then processes SNMP requests over the connection.

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.

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.

These notes describe the new enhancements made to the SimpleAgentPro since Version 8.0 (Feb, 2004).
Added support for HP OpenView Discovery Wizard that discovers, learns and creates simulation maps based on information in HP OpenView database.
This greatly simplifies the tasks of duplicating existing networks instead of just duplicating individual devices.
MIB Browser
The MIB Browser has been enhanced to show changes in data as well as show results in multiple windows. The preferences dialog allows the user to save these settings for subsequent use.
MIB Compiler
A less stringent MIB compiler is now included with the product. The older mibcompiler is also provided for backwards compatibility if required. It uses a best-effort approach to parsing the MIBs and extracts as much information as possible from it.
DHCP requests can now also be made in parallel instead of sequentially as done in the past. This allows the simulation to stress DHCP servers with many requests coming all at once.
MIB Based Learning
In addition to doing snmp walks to learn all the variables supported by an agent, learning can also be restricted to learn only those variables that are present in a specified MIB. Number of rows learnt from a specific table can also be curtailed.
Added support for Tcl based commands to give current snmp port information as well as currently processed object identifier (which for getnext requests might be different than the one in the request).
Added support for automatic mapping of $$MYMAINMACADDR$$ token in the variable file with the device's associated MAC Address.
Command Line Utilities
Added support for carrying out learning on HP OpenView machines that are not running SimpleAgentPro. These tools can then be taken to customer sites to quickly build list of devices to learn from.
SNMP Informs
Added support to provide SNMPv3 discovery based inform generation and retransmission until response/ack is received from the inform receipient.
SimpleAgentPro Ver 8.0 Release Notes
February 18, 2004
These notes describe the new enhancements made to the SimpleAgentPro since Version 7.5 (July 28, 2003).
Added support for Discovery Wizard that discovers, learns and creates simulation maps based on seed router, subnets, and IP ranges.
This greatly simplifies the tasks of duplicating existing networks instead of just duplicating devices one at a time.
The Telnet/CLI interface in SimpleAgentPro is now also available via SSH, as today's secure devices increasingly support SSH instead of Telnet. Users can now login into the simulated devices using SSH and run CLI sessions.
Multiple SSH sessions are supported to the simulated devices and pre-learnt CLI responses can be played back over SSH.
SSH support is currently only available on Solaris and Linux within United States. It is not currently available for export.
Simulated devices now support HTTP/HTTPs in addition to SNMP, SSH, Telnet/CLI, TL1, FTP and TFTP. Now, some management data can be retrieved via SNMP while other data can be got via HTTP/HTTPs.
SimpleAgentPro also includes a simple HTTP learner application that allows you to learn from existing devices and save their HTTP responses so that they can be replayed later.
Added support for Tcl based command to automatically add trap recipients from the SNMPTargetAddrTable data.
Added support for manipulating the object ids returned in SNMP Set responses.
Added support to specify additional varbinds in enterprise specific traps when creating traps from MIBs.
Command Line Utilities
Added support for carrying out SNMP walks in parallel to facilitate faster learning from existing networks at customer sites.
Added support for discovery tools that can be taken at customer sites to quickly build list of devices to learn from.
Added support for learning traps for various trap logs.
User Interface
Added support for graphical display of maps using images.
Telnet Learning
Added support to handle cases where special input is necessary before the login prompt is displayed.
