The usage of the command is as
follows:
fw sam [-v] [-s sam_server] [-t timeout] [-l log] [-f
fw_host] [-C] -n|-i|-I <criteria>
fw sam [-v] [-s sam_server] [-f fw_host] -D options:
-v turn on verbose mode -s sam_server the SAM server to be contacted. Default is localhost -t timeout time in seconds for the inhibit operation. Default is never -l log can be one of the following: nolog, short_noalert, short_alert, long_noalert, long_alert (the last is the default value) -f fw_host the FireWalls to run the operation on. Should be either the name of a FireWalled object, the name of a group of FireWalled objects or one of the predefined names: All and Gateways. Default is All -C cancel the specified operation -n notify every time a connection that matches the specified criteria passes the firewall operations:
-i inhibit connections that match the specified criteria -I inhibit connections that match the specified criteria and close all existing connections that match it -D delete all previous operations criteria may be one of:
a. "src" <ip> match the source address of connections b. "dst" <ip> match the destination address of connections c. "any" <ip> match either the source or destination address of connections d. "srv" <src ip> <dst ip> <service> <protocol> match specific source, destination and service <ip>, <src ip> and <dst ip> may be a
host name or a dotted notation address
<service> may be a service name (e.g. "telnet") or a service number <protocol> may be a protocol name (e.g. "tcp") or a protocol number examples:
1. For the next 20 seconds, notify when someone contacts www.domain.name: fw sam -t 20 -n dst www.domain.name 2. Inhibit 10.0.2.4 from accessing the WEB server on www.domain.name: fw sam -i srv 10.0.2.4 www.domain.name 80 6 3. Cancel the operation from example #2: fw sam -C -i srv 10.0.2.4 www.domain.name 80 6 4. Have the SAM server on firewall1.domain.name cancel all previous SAM operations on the FireWall at firewall2.domain.name: sam -s firewall1.domain.name -f firewall2.us.domain.name -D Accordingly, you should issue the following
command:
If you blocked a source IP Address from accessing the host you protect, use the following: fw sam -C -i src xxx.xxx.xxx.xxx
If you blocked a destination address, use the
following:
fw sam -C -i dst xxx.xxx.xxx.xxx
If you blocked a specific source IP Address,
destination address, and service use the following:
fw sam -C -i srv xxx.xxx.xxx.xxx www.domain.name
service_name
Hope this helps a bit more,
Dimitris.

Can somebody tell me how to unblock the specific IP address which has been
blocked by server sensor 7.0 (Windows 2000 Server SP3 Platform)? I know if
I restart the issDaemon, then all the blocked IP address will be release, but I
don't want all the IP address to be release.
Please help.
Best Regards,
Tony Wu
