NAME

     tcpdrop -- drop TCP connections

SYNOPSIS

     tcpdrop local-address local-port foreign-address foreign-port
     tcpdrop [-l] -a

DESCRIPTION

     The tcpdrop command may be used to drop TCP connections from the command line.

     If -a is specified then tcpdrop will attempt to drop all active connections.  The -l flag may be given to list the tcpdrop invocation to drop
     all active connections one at a time.

     If -a is not specified then only the connection between the given local address local-address, port local-port, and the foreign address
     foreign-address, port foreign-port, will be dropped.

     Addresses and ports may be specified by name or numeric value.  Both IPv4 and IPv6 address formats are supported.

     The addresses and ports may be separated by periods or colons instead of spaces.

EXIT STATUS

     The tcpdrop utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

     If a connection to httpd(8) is causing congestion on a network link, one can drop the TCP session in charge:

	   # sockstat -c | grep httpd
	   www	    httpd      16525 3	tcp4 
		   192.168.5.41:80	192.168.5.1:26747

     The following command will drop the connection:

	   # tcpdrop 192.168.5.41 80 192.168.5.1 26747

     The following command will drop all connections but those to or from port 22, the port used by sshd(8):

	   # tcpdrop -l -a | grep -vw 22 | sh

RLM_IPPOOL_TOOL(8)					      System Manager's Manual						RLM_IPPOOL_TOOL(8)

NAME

       rlm_ippool_tool - dump the contents of the FreeRadius ippool database files

SYNOPSIS

       If an ipaddress is specified then that address is used to limit the actions or output.

       rlm_ippool_tool [-a] [-c] [-o] [-v] session-db index-db [ipaddress]

       Mark the entry nasIP/nasPort as having ipaddress

       rlm_ippool_tool -n session-db index-db ipaddress nasIP nasPort

       Update old format database to new.

       rlm_ippool_tool -u session-db new-session-db

DESCRIPTION

       rlm_ippool_tool dumps the contents of the FreeRADIUS ippool databases for analyses or for removal of active (stuck?) entries.

       Or with the -n argument adds a usage entry to the FreeRADIUS ippool databases.

OPTIONS

       -a     Print all active entries.

       -c     Report number of active entries.

       -r     Remove active entries.

       -v     Verbose report of all entries.

       -o     Assume old database format (nas/port pair, not md5 output).

       -n     Mark the entry nasIP/nasPort as having ipaddress.

       -u     Update old format database to new.

EXAMPLES

       Given the syntax in the FreeRadius radiusd.conf:

	       ippool myippool {
		   range-start = 192.168.1.0
		   range-stop = 192.168.1.255
		   [...]
		   session-db = ${raddbdir}/ip-pool.db
		   ip-index = ${raddbdir}/ip-index.db
	       }

       To see the number of active entries in this pool, use:

	       $ rlm_ippool_tool -c ip-pool.db ip-index.db
	       13

       To see all active entries in this pool, use:

	       $ rlm_ippool_tool -a ip-pool.db ip-index.db
	       192.168.1.5
	       192.168.1.82
	       192.168.1.244
	       192.168.1.57
	       192.168.1.120
	       192.168.1.27
	       [...]

       To see all information about the active entries in the use, use:

	       $ rlm_ippool_tool -av ip-pool.db ip-index.db
	       NAS:172.16.1.1 port:0x2e8 - ipaddr:192.168.1.5 active:1 cli:0 num:1
	       NAS:172.16.1.1 port:0x17c - ipaddr:192.168.1.82 active:1 cli:0 num:1
	       NAS:172.16.1.1 port:0x106 - ipaddr:192.168.1.244 active:1 cli:0 num:1
	       NAS:172.16.1.1 port:0x157 - ipaddr:192.168.1.57 active:1 cli:0 num:1
	       NAS:172.16.1.1 port:0x2d8 - ipaddr:192.168.1.120 active:1 cli:0 num:1
	       NAS:172.16.1.1 port:0x162 - ipaddr:192.168.1.27 active:1 cli:0 num:1
	       [...]

       To see only information of one entry, use:

	       $ rlm_ippool_tool -v ip-pool.db ip-index.db 192.168.1.1
	       NAS:172.16.1.1 port:0x90 - ipaddr:192.168.1.1 active:0 cli:0 num:0

       To add an IP address usage entry, use:

	       $ rlm_ippool_tool -n ip-pool.db ip-index.db 192.168.1.1 172.16.1.1 0x90
	       rlm_ippool_tool: Allocating ip to nas/port: 172.16.1.1/144
	       rlm_ippool_tool: num: 1
	       rlm_ippool_tool: Allocated ip 192.168.1.1 to client on nas 172.16.1.1,port 144
