Thanks. I have firewalled nfs ports and ran nmap from some other server. nmap can still get the listening ports like following<br />
<br />
PORT &nbsp; &nbsp; STATE &nbsp; &nbsp;SERVICE &nbsp; &nbsp; &nbsp; &nbsp;VERSION<br />
111/tcp &nbsp;filtered rpcbind<br />
2049/tcp filtered nfs<br />
4000/tcp filtered remoteanything<br />
<br />
is there a way to get rid of filtered ports showing up from nmap results.<br />
<br />

What is the issue you are trying to resolve?<br />
Disable the services that you do not need. &nbsp;This way the ports will not be listend.

Hi experts,<br />
&nbsp; Is there a way to make nfs daemons to listen only on tcp ports. i know we can using proto=tcp on client when we mount. but is there way to make it listen on tcp on the server side.<br />
<br />
&nbsp;Also is there way to make syslogd (514) listen on tcp. &nbsp;we are running RHEL5.5.

NFS  and syslogd on linux

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

The Linux operating system, in all its flavors, has its own share of security flaws that allow intrusions, but there are various mechanisms by which these flaws can be removed, generally divided into two parts: authentication and access control. Authentication is responsible for ensuring that a user requesting access to the system is really the user with the account, while access control is responsible for controlling which resources each account has access to and what kind of access is permitted.

Linux Security

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
