inetd: Disable inetd Connection Logging for individual Services

Noticed a large number of unwanted constant connection messages in my system messages file.

The above is coming from my Veritas Netbackup network connection daemon which is constantly filling up my messages file during its nightly backup procedure.

If inetd is running, the "tracing" feature can be used to log information about the source of any network connections seen by the daemon. Rather than disabling inetd tracing for all services, the administrator has the option of disabling tracing for individual services with inetadm -m svcname tcp_trace=FALSE , where is the name of the specific service that should use tracing.

1. The following command will display the properties for the vnetd service.

 # inetadm -l svc:/network/vnetd/tcp:default
 SCOPE    NAME=VALUE
          name="vnetd"
          endpoint_type="stream"
          proto="tcp"
          isrpc=FALSE
          wait=FALSE
          exec="/usr/openv/bin/vnetd"
          user="root"
 default  bind_addr=""
 default  bind_fail_max=-1
 default  bind_fail_interval=-1
 default  max_con_rate=-1
 default  max_copies=-1
 default  con_rate_offline=-1
 default  failrate_cnt=40
 default  failrate_interval=60
 default  inherit_env=TRUE
 default  tcp_trace=TRUE
 default  tcp_wrappers=TRUE
 default  connection_backlog=10

2. The following command will disable tracing for the vnetd service

 # inetadm -m svc:/network/vnetd/tcp:default tcp_trace=FALSE

3. Confirm the changes using the display option again.

 
 # inetadm -l svc:/network/vnetd/tcp:default
 SCOPE    NAME=VALUE
          name="vnetd"
          endpoint_type="stream"
          proto="tcp"
          isrpc=FALSE
          wait=FALSE
          exec="/usr/openv/bin/vnetd"
          user="root"
 default  bind_addr=""
 default  bind_fail_max=-1
 default  bind_fail_interval=-1
 default  max_con_rate=-1
 default  max_copies=-1
 default  con_rate_offline=-1
 default  failrate_cnt=40
 default  failrate_interval=60
 default  inherit_env=TRUE
          tcp_trace=FALSE
 default  tcp_wrappers=TRUE
 default  connection_backlog=10
