tcptraceroute is a traceroute implementation using TCP packets. The more traditional traceroute(8) sends out either UDP or ICMP ECHO packets with a TTL of one, and increments the TTL until the destination has been reached. By printing the gateways that generate ICMP time exceeded messages along the way, it is able to determine the path packets are taking to reach the destination. The problem is that with the widespread use of firewalls on the modern Internet, many of the packets that traceroute(8) sends out end up being filtered, making it impossible to completely trace the path to the destination. However, in many cases, these firewalls will permit inbound TCP packets to specific ports that hosts sitting behind the firewall are listening for connections on. By sending out TCP SYN packets instead of UDP or ICMP ECHO packets, tcptraceroute is able to bypass the most common firewall filters.

Net::Printer ============ Perl module for directly printing to a print server/printer without having to create a pipe to either lpr or lp. This essentially mimics what the BSD LPR program does by connecting directly to the line printer printer port (almost always 515), and transmitting the data and control information to the print server. Please note that this module only communicates with the BSD Line Printer Daemon Protocol as described in RFC-1179. It does not natively speak to remote print servers via SMB, Apple-Talk or Netware. Remote print services running lpsched, such as Sun Solaris or other Sys V-derived operating systems, will work so long as the print spoolers are set up to understand the BSD protocol. Most modern network-capable laser printers, such as those manufactured by HP and LexMark, also "speak" BSD.

CDO is a collection of command line Operators to manipulate and analyse Climate model Data. Supported file formats are GRIB, netCDF, SERVICE, EXTRA and IEG. There are more than 250 operators available. The following table gives a short overview about the main categories. * File information (info, sinfo, diff, ...) * File operations (copy, cat, merge, split*, ...) * Selection (selcode, selvar, sellevel, seltimestep, ...) * Missing values (setctomiss, setmisstoc, setrtomiss) * Arithmetic (add, sub, mul, div, ...) * Mathematical functions (sqrt, exp, log, sin, cos, ...) * Comparision (eq, ne, le, lt, ge, gt, ...) * Conditions (ifthen, ifnotthen, ifthenc, ifnotthenc) * Field statistic (fldsum, fldavg, fldstd, fldmin, fldmax, ...) * Vertical statistic (vertsum, vertavg, vertstd, vertmin, ...) * Time range statistic (timavg, yearavg, monavg, dayavg, ...) * Ensemble statistic (enssum, ensavg, ensstd, ensmin, ...) * Regression (detrend) * Field interpolation (remapbil, remapcon, remapdis, ...) * Vertical interpolation (ml2pl, ml2hl) * Time interpolation (inttime, intyear)

Nmap is a utility for network exploration and security auditing. It supports various types of host discovery (determine which hosts are up), many port scanning techniques for different protocols, version detection (determine service protocols and application versions listening behind ports), and TCP/IP stack fingerprinting (remote host OS or device identification). Nmap also offers flexible target and port specification, decoy/stealth scanning, sunRPC scanning, and much more. Also included is Ncat, the nc(1) work-a-like of the Nmap project. Refer to the separate port security/zenmap for those parts of the Nmap toolset which depend on python. The translated manual pages for Nmap are contained in security/nmap-i18n-man. See the web page and the Phrack Magazine article (Volume 7, Issue 51 September 01, 1997, article 11 of 17) http://nmap.org/p51-11.html

Tie::EncryptedHash augments Perl hash semantics to build secure, encrypting containers of data. Tie::EncryptedHash introduces special hash fields that are coupled with encrypt/decrypt routines to encrypt assignments at STORE() and decrypt retrievals at FETCH(). By design, encrypting fields are associated with keys that begin in single underscore. The remaining keyspace is used for accessing normal hash fields, which are retained without modification. While the password is set, a Tie::EncryptedHash behaves exactly like a standard Perl hash. This is its transparent mode of access. Encrypting and normal fields are identical in this mode. When password is deleted, encrypting fields are accessible only as ciphertext. This is Tie::EncryptedHash's opaque mode of access, optimized for serialization.

Rsyslog is an enhanced multi-threaded syslogd with a focus on security and reliability. Among others, it offers support for on-demand disk buffering, reliable syslog over TCP, SSL, TLS and RELP, writing to databases (MySQL, PostgreSQL, Oracle, and many more), email alerting, fully configurable output formats (including high-precision timestamps), the ability to filter on any part of the syslog message, on-the-wire message compression, and the ability to convert text files to syslog. It is a drop-in replacement for stock syslogd and able to work with the same configuration file syntax. Its advanced features make it suitable for enterprise-class, encryption protected syslog relay chains while at the same time being very easy to setup for the novice user. Tracking v7-devel

DVD+RW Tools by Andy Polyakov. This software allows one to perform DVD recording using a DVD burner, primarily via the "growisofs" utility. growisofs was originally designed as a frontend to mkisofs to facilitate appending of data to ISO9660 volumes residing on random-access media such as DVD+RW, DVD-RAM, plain files, hard disk partitions. In the course of development general purpose DVD recording support was implemented, and as of now growisofs supports not only random-access media, but even mastering of multi-session DVD media such as DVD+R and DVD-R/-RW. In addition growisofs supports first-/single-session recording of arbitrary pre-mastered image (formatted as UDF, ISO9660, or any other file system, if formatted at all) to all supported DVD media types.

SMBNetFS is a filesystem that allow you to use samba/microsoft network in the same manner as the network neighborhood in Microsoft Windows. Featuries: * you can use Samba/Microsoft network as a regular Unix filesystem * workgroup/computer/share entries are dynamically created * Windows domain supported * kerberos support (New) * user defined workgroup/link/hosts are supported * national character supported * in config files you can specify different user/password to access different network shares * you can access any computer in the world by "cd mountpoint/ip-addr" command, where "ip-addr" is the IP address of the desired computer. Do not warry that there is no file with such name :-) * command "cd mountpoint/username:password@computer_or_ip" allows you to access "computer_or_ip" as user "username" with password "password" (this is insecure, but usefull)

MultiTail lets you view one or multiple files like the original tail program. The difference is that it creates multiple windows on your console (with ncurses). It can also monitor wildcards: if another file matching the wildcard has a more recent modification date, it will automatically switch to that file. That way you can, for example, monitor a complete directory of files. Merging of 2 or even more logfiles is possible. It can also use colors while displaying the logfiles (through regular expressions), for faster recognition of what is important and what not. It can also filter lines (again with regular expressions). It has interactive menus for editing given regular expressions and deleting and adding windows. One can also have windows with the output of shell scripts and other software. When viewing the output of external software, MultiTail can mimic the functionality of tools like 'watch' and such.
