Top Forums UNIX for Dummies Questions & Answers I have firewall rules to open ports, why telnet refuses connection? Post 302754329 by Corona688 on Thursday 10th of January 2013 12:08:43 PM

It doesn't matter how many open ports you have if your telnet daemon isn't actually using these ports.

Consider that any other daemon on your system could use these ports too. The firewall doesn't decide which program gets an open port. You have to configure the program itself to use other ports.

Firewall Ports

Could someone please settle an inter-office argument? Will your network traffic be slower through a firewall on any other port other than port 80. In other words, is port 80 faster than any other port you open on the firewall. I say no. Thanks in advance for the help! (2 Replies)

NAME
kadmind -- server for administrative access to Kerberos database SYNOPSIS
kadmind [-c file | --config-file=file] [-k file | --key-file=file] [--keytab=keytab] [-r realm | --realm=realm] [-d | --debug] [-p port | --ports=port] DESCRIPTION
kadmind listens for requests for changes to the Kerberos database and performs these, subject to permissions. When starting, if stdin is a socket it assumes that it has been started by inetd(8), otherwise it behaves as a daemon, forking processes for each new connection. The --debug option causes kadmind to accept exactly one connection, which is useful for debugging. The kpasswdd(8) daemon is responsible for the Kerberos 5 password changing protocol (used by kpasswd(1)). This daemon should only be run on the master server, and not on any slaves. Principals are always allowed to change their own password and list their own principal. Apart from that, doing any operation requires per- mission explicitly added in the ACL file /var/heimdal/kadmind.acl. The format of this file is: principal rights [principal-pattern] Where rights is any (comma separated) combination of: o change-password or cpw o list o delete o modify o add o get o get-keys o all And the optional principal-pattern restricts the rights to operations on principals that match the glob-style pattern. Supported options: -c file, --config-file=file location of config file -k file, --key-file=file location of master key file --keytab=keytab what keytab to use -r realm, --realm=realm realm to use -d, --debug enable debugging -p port, --ports=port ports to listen to. By default, if run as a daemon, it listens to port 749, but you can add any number of ports with this option. The port string is a whitespace separated list of port specifications, with the special string ``+'' representing the default port. FILES
/var/heimdal/kadmind.acl EXAMPLES
This will cause kadmind to listen to port 4711 in addition to any compiled in defaults: kadmind --ports="+ 4711" & This acl file will grant Joe all rights, and allow Mallory to view and add host principals, as well as extract host principal keys (e.g., into keytabs). joe/admin@EXAMPLE.COM all mallory/admin@EXAMPLE.COM add,get-keys host/*@EXAMPLE.COM SEE ALSO
