Re: Programming Language for Network Engingeers. [7:58032]
I would definitely say Perl. It runs on both Unix and Winblows so its portable. I used to write scripts for monitoring network services, connecting to ports ie. There is even a library to easily write your own network sniffer and a very good scokets library as well.

RE: Programming Language for Network Engingeers. [7:58032]
VB Is usually a good one to learn for a network engineer. Given that most of the systems I work on run some form of windows, I found it to be an easy language to learn and very useful for creating quick custom tools that the end user may need (such as logging into all the routers and saving the Config to a tftp server every day). Other then that just learn scripting languages such as VBScript for windows and SH for linux/unix.

RE: Programming Language for Network Engingeers. [7:58032]
Perl is good to know, but it is a scripting language. As far as programming goes, I like C and C++. Many tools are available using Perl, C, and C++, that can make a network engineers job much easier. Plus, the insight gained by knowing a good programming language is priceless. It's not necessary, but recommend! -Ted Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=58039&t=58032 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: Programming Language for Network Engingeers. [7:58032]
Perl - Use it to do many things like parsing log files, parsing and even generating config files. Too many uses to list. Once you learn what perl is and what it can do, you WILL find uses for it. Expect - Use it to script things that otherwise would only be able to occur interactively with network devices, such as Telnet to a router, log on, dump the config to a tftp server. Or, create an expect script to log on to a router, copy tftp image to flash and reload, then set this to run via a cron job for an unattended router upgrade (yes, that is risky but some people can get away with it :-). If you run both on unix/linux, learn bash or whatever shell you plan on using because you will find many useful functions built into the shell. It isn't unrealistic to setup a generic unix/linux system with Perl, Expect and a TFTP server to to manage all of your device configs, images and logfiles. -Original Message- From: John Tafasi [mailto:[EMAIL PROTECTED]] Sent: Monday, November 25, 2002 10:28 AM To: [EMAIL PROTECTED] Subject: Programming Language for Network Engingeers.

For operational use, Perl (unless you already know awk). I very, very strongly recommend using this on a UNIX box, so you can avoid reinventing the wheel where utilities exist that can be piped together. It is a decent language for scanning logs and the like, although it has some deficiencies if you want to do statistical analysis. Tcl is another possibility, along with the expect application. This is better for coding "automated operator" scripts. C and/or C++ have their role. I've found it much more cumbersome to do interprocess communications (beyond a simple telnet script) in Perl. These languages are also better for writing statistical analysis, since Perl is really text oriented. It's arguable that they are more maintainable. As an aside, all router code that I have actually looked at (Cisco, Nortel, NextHop, Zebra, etc.) is almost always in C, although there's some C++ here and there. You're more likely to see the OO languages in network managers and the like.

I don't know of any specific books for Network Engineers, but I would start with the O'Reilly books on Perl and Expect.

Again, depends on your definition of network engineer, but John Moy's second book goes through the programming of a public domain OSPF implementation. That's pretty network-ish. There's a lot of material on the Internet, primarily aimed at service providers. Check through www.nanog.org, www.radb.net, www.ripe.net, and the NANOG mailing list. For statistical analysis, www.caida.org is a good starting place. Apropos of not much, I once wrote a complete analyzer for IBM NCP configurations.
