tcpdmatch – tcp wrapper oracle Synopsys tcpdmatch [-d] daemon client tcpdmatch [-d] daemon[@server] [user@]client Description tcpdmatch predicts how the tcp wrapper would handle a specific request for service. Examples are given below. The program examines the tcpd access control tables (default /etc/hosts.allow and /etc/hosts.deny) and prints its conclusion. For maximal accuracy, it extracts additional information…
tcpdchk – tcp wrapper configuration checker Synopsis tcpdchk [-a] [-d] [-i inet_conf] [-v] Description tcpdchk examines your tcp wrapper configuration and reports all potential and real problems it can find. The program examines the tcpd access control files (by default, these are /etc/hosts.allow and /etc/hosts.deny), and compares the entries in these files against entries in…
tcpd_selinux – Security Enhanced Linux Policy for the tcpd processes Description Security-Enhanced Linux secures the tcpd processes via flexible mandatory access control. The tcpd processes execute with the tcpd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. For example: ps -eZ | grep…
tcpd – access control facility for internet services Description The tcpd program can be set up to monitor incoming requests for telnet, finger, ftp, exec, rsh, rlogin, tftp, talk, comsat and other services that have a one-to-one mapping onto executable files.
