pmacct is a small set of passive network monitoring tools to account, filter, classify, aggregate, and export IPv4 and IPv6 traffic. A pluggable and flexible architecture allows storing collected network data in memory tables, RDBMSs (MySQL, SQLite, PostgreSQL, BDB), and flat files, and also export via IPFIX, NetFlow, or sFlow protocols to remote collectors. pmacct features fully customizable historical data breakdown, sampling, BGP correlation, tagging, and triggers. Libpcap, ULOG, sFlow v2/v4/v5, NetFlow v1/v5/v7/v8/v9, and IPFIX are supported data capturing methods.
G4L is a hard disk and partition imaging and cloning tool. The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server. A drive can be cloned using the "Click'n'Clone" function. G4L supports file splitting if the local filesystem does not support writing files larger than 2GB. The included kernel supports ATA, serial-ATA, and SCSI drives. Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.
The sysstat package contains the sar, sadf, iostat, nfsiostat, cifsiostat, mpstat, and pidstat commands for Linux. The sar command collects and reports system activity information. The statistics reported by sar concern I/O transfer rates, paging activity, process-related activites, interrupts, network activity, memory and swap space utilization, CPU utilization, kernel activities, and TTY statistics, among others. The sadf command may be used to display data collected by sar in various formats. The iostat command reports CPU statistics and I/O statistics for tty devices and disks. The pidstat command reports statistics for Linux processes. The mpstat command reports global and per-processor statistics. The nfsiostat command reports I/O statistics for network filesystems. The cifsiostat command reports I/O statistics for CIFS filesystems.
slapt-get is an APT-like system for Slackware package management. It allows you to search Slackware mirrors and third-party package sources (such as www.linuxpackages.net) for packages, compare them with installed packages, and install new packages or upgrade installed packages, all with a few simple commands.
Virtualmin is a Webmin module that simplifies the process of setting up and managing virtual servers. It can create Apache virtual hosts, BIND DNS domains, MySQL and PostgreSQL databases, and set up Sendmail or Postfix to accept email for a domain. It can also manage mailboxes and mail aliases within a domain.
The netpipes package makes TCP/IP streams usable in shell scripts. It can also simplify client/server code by allowing the programmer to skip all the tedious programming bits related to sockets and concentrate on writing a filter/service. <P>Applications of these utilities can include file transfer, network backups, HTTP queries, remote procedure calls, and TCP daemon testing. <P>The SSL encryption filter available in the US/Canada version can be applied by shell scripts communicating with secure HTTPDs and can be used to make an SSL IMAPD out of a non-SSL one. (requires the SSLeay library).
Req is a tracking system. People with problems or questions send requests via email to a group responsible for dealing with those issues. Those requests are assigned numbers that can be tracked and managed in various ways. The group handling the requests needs to have access to a UNIX computer or network.
Mrsh is a tool that uses pipes to allow a system administrator to issue a command on many systems at the same time. The user can select any remote shell command they wish. This tool was designed out of necessity. Mrsh is known to compile flawlessly under RedHat Linux, and Solaris 2.5 and 2.6.
