Ensure rexd daemon is not in use
MediumLevel 1Automatedaix
Description
This entry starts the rxed service when required. This service should be disabled if it is not required. The rexd daemon executes programs for remote machines when a client issues a request to execute a program on a remote machine. The inetd daemon starts the rexd daemon from the /etc/inetd.conf file. Audit: `lssrc -s inetd -l` must not list the service (count 0).
How it is checked
Audit method: Shell command
shell
command -v lssrc >/dev/null 2>&1 || exit 1; n=$(lssrc -s inetd -l 2>/dev/null | grep -c '[[:blank:]]rexd'); echo "$n"- Expected output
0
How it is fixed
Fix method: Guidance or infrastructure patch
Use chsubserver to disable this service in /etc/inetd.conf: chsubserver -r inetd -C /etc/inetd.conf -d -v 'rexd' -p 'tcp' refresh -s inetd
