Affected Versions:FreeBSD 8.0FreeBSD 7.2 vulnerability description:Bugtraq id: 42533 FreeBSD is an open-source Unix system that runs on the Intel Platform and can be freely used. The setusercontext () function in the lib/libutil/login_class.c file is used to apply specific user settings when running with the permissions of other users. This allows local users to create special ~ /. Login_conf file and use OpenSSH to log on to change some restricted re

I have been compiling and installing the latest mono version 2.4.2.3 on FreeBSD for the past two days. However, I have tried many times and cannot compile it normally, so I have to give up temporarily. Then we will try to install it in the simplest way, ports. To install the latest mono version, update ports with the following command:ReferencePortsnap fetch ExtractPortsnap fetch update It should be noted that portsnap fetch extract only needs t

I did a minimal installation of FreeBSD a long time ago. At the time, I did not install manual pages. To later install these man pages, I shocould be able to do the following: Run sysinstall# Sysinstall Select configureConfigure do post-InstallConfiguration of FreeBSD Select DistributionsDistributions install additional distribution Sets Select man[X] MAN system manual pages-recommended

When adding a route, if you want it to be valid when the server is restarted, write the command to/etc/rc. Local. However, the routing operations are different in Linux and FreeBSD, with the following differences: Linux: The following is a code snippet:View routes:/Sbin/routeAdd route:/Sbin/route add-host 172.16.78.226 GW 10.55.40.1/Sbin/route add-net 172.16.20.0/24 GW 10.55.40.1Delete A route/Sbin/route del-host 172.16.78.226 GW 10.55.40.1/

FreeBSD runs x normally. Unlike Linux, FreeBSD does not play with Kde, So I rarely use Kde, and gnome often suffers errors. I had to install an xfce, but the xfce in ports is not the latest version, and I am too lazy to install it after I downloaded more than a dozen packages. Hey, I almost forgot what I want to do. This time I want to install the environment is eclipse 3.1 + jdk1.4.2-P6 + jboss-3.2.5 Jboss

FreeBSD has been used for some time. Many of the commands are commonly used during this period. It is easy to use FreeBSD by learning to use these commands. Now I will summarize the commands I used during this period. Many of them are very similar to Linux, and some of them are still learned from Linux materials, in any case, it is easier to search for Linux on Google. 1. Display directories and filesLs

step is to use the Vpopmail software to enable the server to support virtual domains. Because at this stage, the mail server can only provide mail services to users on FreeBSD. If every New Mail User is added to the system, this server not only wastes resources but also brings security risks. It currently only supports one domain name mail.itp.swjtu.edu.cn. Vpopmail provides the virtual domain function and converts/etc/passwd-based authentication to/

First describes how to establish a high-speed DNS cache server on FreeBSD, citing the words in the Freebs D Chinese Manual: A cached domain name server is a domain name server that does not provide authoritative resolution for any domain. It simply completes the query itself and remembers the queries for subsequent use. To set up such a server, simply configure a domain name server as usual, without configuring the domain. The installation is as fol

Because the file system is a very important part of the system, the task of maintaining the file system is also very important. This task includes checking, fixing the file system, and adjusting the tree to fit the changes in the system, adding new storage devices, etc. Check your hard drive There is no problem with the file system when using FreeBSD under normal circumstances. However, in some cases, if the computer's power is cut off without a nor
