Ensure pcnfsd daemon is not in use
Description
This entry starts the pcnfsd daemon when required. This service is an authentication and printing program, which uses NFS to provide file transfer services. The pcnfsd service is an authentication and printing program, which uses NFS to provide file transfer services. This service is vulnerable and exploitable and permits the machine to be compromised both locally and remotely. Audit: `lssrc -s inetd -l` must not list the service (count 0).
How it is checked
Audit method: Shell command
command -v lssrc >/dev/null 2>&1 || exit 1; n=$(lssrc -s inetd -l 2>/dev/null | grep -c 'pcnfsd'); echo "$n"- Expected output
0
How it is fixed
Fix method: Guidance or infrastructure patch
In /etc/inetd.conf, comment out the pcnfsd entry and refresh the inetd process: chsubserver -r inetd -C /etc/inetd.conf -d -v 'pcnfsd' -p udp lssrc -s inetd && refresh -s inetd
