Subversion depends on a number of third party tools and libraries.Some of them are only required to run a Subversion server; others are necessary just for a Subversion client. This section explains what other tools and libraries will be required so that Subversion can be built with the set of features you want

Lots of programmers like PHP for its ability to code and develop web applications fast. Code-debugging is a lot easier than with PERL or C. However, there is one thing a lot of developers are puzzled about, “How to run PHP Scripts with crontab?†Cron is normally available on all Unix and Linux distributions; if [...]

In retrospect this was surprising (since we had not requested any DNS software during the FC2 installation procedure – FC2 install was kind enough to do it anyway) and perhaps we should have removed this version before installing since we ended up with -in our view – an incomplete installation. We may have had a complete install if we had done this – maybe not. We issued the following command to upgrade the installation:

Most Linux distributions ship with tcp_wrappers “wrapping” all your TCP services. A tcp_wrapper (known as /usr/sbin/tcpd) is invoked from/sbin/inetd instead of the real service, such as telnet or ftp. tcpd then checks the host that is requesting the service and either executes the real server or denies access from that host. tcpd allows you to restrict access to your tcp services. You should make [...]

Here is a simple command to auto repair, check and optimize all the tables in all databases running on a MySQL server: mysqlcheck -u root -p –auto-repair –check –optimize –all-databases mysqlcheck is available in MySQL 3.23.38 and later. mysqlcheck uses the SQL statements CHECK TABLE, REPAIR TABLE, ANALYZE TABLE, and OPTIMIZE TABLE in a convenient [...]

The sg driver permits user applications to send SCSI commands to devices that understand them. SCSI commands are 6, 10, 12 or 16 bytes long [1]. The SCSI disk driver (sd), once device initialization is complete, only sends SCSI READ and WRITE commands. There a several other interesting things one might want to do, for [...]

You can limit users’ ability to browse the Internet with access control lists (ACLs). Each ACL line defines a particular type of activity, such as an access time or source network, they are then linked to an http_access statement that tells Squid whether or not to deny or allow traffic that matches the ACL. Squid [...]

Users configure their web browsers to use the Squid proxy server instead of going to the web directly. The Squid server then checks its web cache for the web information requested by the user. It will return any matching information that finds in its cache, and if not, it will go to the web to [...]

The SSL protocol includes two sub-protocols: the SSL record protocol and the SSL handshake protocol. The SSL record protocol defines the format used to transmit data. The SSL handshake protocol involves using the SSL record protocol to exchange a series of messages between an SSL-enabled server and an SSL-enabled client when they first establish an [...]

First you should check, whether and which IPv6 addresses are already configured (perhaps auto-magically during stateless auto-configuration). Using “ip” Usage: Â # /sbin/ip -6 addr show dev <interface> Â Example for a static configured host: Â # /sbin/ip -6 addr show dev eth0 2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_ fast qlen 100 inet6 fe80::210:a4ff:fee3:9566/10 [...]

When a Linux system has been running for a while memory fragmentation can increase which depends heavily on the nature of the applications that are running on it. The more processes allocate and free memory, the quicker memory becomes fragmented. And the kernel may not always be able to defragment enough memory for a requested [...]

The xinetd daemon is a replacement for inetd, the internet services daemon. It monitors the ports for all network services configured in /etc/xinetd.d, and starts the services in response to incoming connections. To check if xinetd is enabled and running, execute: # chkconfig –list xinetd xinetd 0:off 1:off 2:off 3:on 4:on 5:on 6:off # /etc/init.d/xinetd [...]

On Red Hat systems you can list all services which are started at bootup using the following command: chkconfig –list |grep on You will notice that there are quite a lot of services enabled on your system. But many runlevel services (Stand-Alone Services) are not network related services like kudzu which is responsible for detecting [...]

Unlike the built-in dhclient, your FreeBSD system does not come with DHCP server software. This is because you only need to configure a DHCP server if you want to lease out IP configuration for your own network. However, there are two ports that allow you to create your own DHCP server. The first is known [...]
