RE: How to query the computer's ip address?
Hi,
Silly question, maybe, but is there a simple command to query the
computer's
ip address? Something similar to 'hostname' for finding the computer's
hostname.
I need the four dot-separated ip numbers.
I can analyze the output of 'ifconfig', but isn't there an easier way.
For the sake of looking for a command that might do this, i whipped up
this long one-liner:
ifconfig | perl -nle 'print $1 if(/(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/)'
note that this will print the first ip address it finds of each line
seperated by a newline, so be prepared to handle more than one.

Ctrl+Alt+Delete
Hi, this is a rather auxilary question but my curiosity overpowered my self control. This is also more of a i386 specific question, but then again i'm not completely sure if FreeBSD handles it the same way on different machines. Does anyone on the list know what Ctrl+Alt+Delete does on a running FreeBSD machine? The funniest part of this question is that FreeBSD has never frozen on me, so that I could actually find out. I run it on my server systems, and i don't want to test it and then run the risk of ruining some drives. -rian _ Let the new MSN Premium Internet Software make the most of your high-speed experience. http://join.msn.com/?pgmarket=en-uspage=byoa/premST=1 ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: Another Newbie Question: C or C++
I would recommend not trying to learn C or C++ by yourself from a book. The fastest (and best way) to learn the right stuff is to take coursework from a university or community college. Not that I like disagreeing for no good reason, but I wholeheartedly disagree with that statement. If the courses are any good, you'll get feedback, and you'll be paced and challenged with projects designed to help you learn. Going it alone in an unguided environment will only familiarize you the lesser aspects of a language, if you last that long. The difficult and most important aspects of the language (like pointers, virtual functions, references) will become almost insurmountable trial-and-error obstacles if you try to teach yourself. If you want to get a lower paying and boring job programming in C/C++ for whatever reason and have a piece of paper that says you can have that job, I recommend wasting 4-6 months taking a course in your spare time to learn C/C++. If you want to be top of your game and learn C/C++ without wasting time on topics that take you a minute to understand, get a good book, practice the topics you have learned at your own pace, get numorous code examples for things you may want to do (sockets, GUI, OpenGL, ncurses, threading, kernel interfacing) from the glorious and infinite internet and emulate good programming style (using const qualifiers in C++, using #defines in C, etc.). Also be prepared to teach yourself because you may not always be prepared for a job you may find yourself with; learn how to easily learn and use external libraries. The best programmers will teach themselves. A statement that may be on the borderline of opinion to fact by constant example. After all the first programmer, in fact, taught herself. -Rian Hunter _ MSN Messenger with backgrounds, emoticons and more. http://www.msnmessenger-download.com/tracking/cdp_customize ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Another Newbie Question: C or C++
I need to buy a book on C or C++ to help me in FreeBSD. Which would be better to buy? If you just want to start programming in FreeBSD, Learn C as well as you can. The route I took was learning basic programming skills then reading The C Programming Language by KR, it's an excellent book if you are already very familiar with the computer and have some basic programming skills (make sure you know your c development enviroment and how to use gcc). The book is so great because not only does it teach C syntax, the examples open your mind to writing simple and efficient code in a C style, and it even has a small UNIX programming tutorial toward the end (on how to implement some of the standard library functions in a UNIX system). That book and a good familiarity with the man pages is really all you need to get started coding on FreeBSD. If you are still a little lost and really want to go on the quick route to good BSD programming, read UNIX Network Programming by W. Richard Stevens. The original edition introduces you to good fundamental knowledge of the UNIX system and archictecture (process model, system calls, and IPC) then it goes right to socket programming which is a must to know especially in this day and age. The later editions seperate the actual socket programming from the unix stuff but go intensely in depth. That's why i'm fonder of the first edition, concise and smart. I first thought a book on C would be best, because the OS is written in C. But, now I'm not sure because I read that gcc can compile C++ too (so, I'm assuming C++ must get used too). Now that you've had good practice with C and UNIX programming, learning libraries (GTK, QT, pthreads, GD to name a few) is simply a matter of reference and learning any other language else is simply a matter of syntax and style, and everything will come very easy. If you haven't learned C++ by that point just figure out what Object Oriented programming is (it'll beautify your life), get a reference book, look at some coding examples, and no sweat. Java? Perl? Python? Javascript? Visual Basic (haha)? They'll all just be minor changes in syntax and style when in comes to C/C++ (except for python, hah). Hope that helps and good luck! -Rian Hunter _ MSN Messenger with backgrounds, emoticons and more. http://www.msnmessenger-download.com/tracking/cdp_customize ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Custom FreeBSD boot floppy??
Hi Everyone! The MBR on my hard disk is corrupted (or sometimes is), after re-installing FreeBSD it was not overwritten and fixed even though the complete system was. So when i need to boot i use the bootcds i used to install FreeBSD and at boot0 i press any key (during rapid / - \ - spinnings) and boot my hard drive using the command 0:ad(a,0)/boot/loader. When there is a power failure, it requires me to go back to the system and repeat the process. How could i make a custom boot floppy (or even boot cd) to load 0:ad(a,0)/boot/loader automatically, since the MBR never gets repaired (however many times i've tried). If this information is already documented somewhere, a point in the right direction will be more than sufficient, even if the information is about MBR repair and installation of the FreeBSD boot loader. I am using 4.8-RELEASE, thanks to all in advance! -Rian Hunter _ Send instant messages to anyone on your contact list with MSN Messenger 6.0.

Console Keyboard Difficulty
Hello! I am using FreeBSD 4.8. I recently installed emacs21 from the ports system but i'm afraid there may be a keybinding conflict. In my regular console and Xterm console Backspace is mapped at ctrl-h apparently. I think emacs knows this as backspace deletes the one character behind the cursur position and so does ctrl-h in emacs. The problem is that ctrl-h is supposed to activate the help system in emacs. Is there an (elegant) solution to this problem? I know that for a while my keys weren't always working so well, but they were minor problems so i ignored them. For example in Xterm pressing delete inserts and '~' character and a console beep, in the regular console pressing delete inserts a backspace.

TCP/IP: Operation Timed Out
Hello All! I manage a general mail server for my organization and recently i have been receiving complaints that not all their messages are being sent. A quick check to the maillog and i noticed that many of the mail servers of the receivers are getting Operation timed out responses. I manually checked connecting to these servers using telnet to see if it was just my mta, but to my surprise telnet was unable to connect as well! At home i tried connecting to these servers via telnet on port 25 as well, and it worked with ease. Then immediatly I ssh'ed to our remote mail server and telnet'ed to these operation timed out mail servers on port 25 and still same thing. Now this shocked me, how could i be easily connecting to the mail servers from home, and from the location of our mail server, not be able to. It connects to other mail servers there are just a few that do not work including: smtp1.dadeschools.net mail1.dadeschools.net oitmail.dade.k12.fl.us sbabmail.dade.k12.fl.us 7841exch2.tecmiami.com It's not a DNS problem as the dns resolves the same ip address from home and where the server resides. I'm not sure if it is solely our mail server or it is all the computers on our LAN that are unable to connect, i willl have to examine this when i get there sometime this week. The mail server is connected directly to the internet and is assigned a public ip address (it is not behind a router filewall or is not forwarded packets through NAT). The host address of our mail server is mail.e-equality.org. Does anyone know the nature of this problem or how to solve it? Could it be faulty design of the network route from our mail server to theirs? Or maybe our TTL settings on the packets are too small. -Rian Hunter _ Get 10MB of e-mail storage!

Re: TCP/IP: Operation Timed Out
Thank you for your help but after looking in to the problem, i realized it is not the ident protocol. This could be a problem due to timeouts with the ident protocol, also known as auth, which uses port 113. Most mailservers will try and do an ident check on you when you connect to them. If your firewall just drops the incoming connection, then the server at the other end will just have to wait out the timeout period. While ident is meant to be a security measure, it's practically worthless as it's too easy to lie to, and if you don't lie, then it's a leak of what should be private information. I tried connecting the un-connectable servers via Windows and FreeBSD using telnet at home and it works, and i am not running any sort of ident server. Connecting to the servers where the mail server lives gives me the operation timed out message under my MTA (not sendmail for note) as well as Telnet, even after flushing all firewall rules. So i suspect my problem lies elsewhere. Thank you for your concern though. -Rian Hunter I manage a general mail server for my organization and recently i have been receiving complaints that not all their messages are being sent.

MBR Corruption and Restore
Hello All! Unfortunatly, i was having a minor hard disk problem on my first FreeBSD installation, and (so used to Debian) i thought i could fsck after shutdown now. Apparently this was not the case, as my file systems were still mounted. After a quick re-install, with backups, it appears my MBR is corrupted as it will not start the /boot/loader and my BIOS recognizes my disk as a non system disk (FreeBSD has been re-installed, to get into the system i use the boot2 from the bootable CD). Is there anyway i can manually install the FreeBSD boot loader while in the system? I figured it is dd'ing the /boot files to the beginning of my hard disk, but i don't know what location nor how safe this is.

POP3 user configuration
Hello all! I'm setting up a POP3/SMTP server (going to use qpopper/sendmail) for my community computer access center and i have little experience setting up a pop3 server (i have more experience setting up a private smtp relay server). My primary question is how can i set up user accounts strictly for POP3 access without shell access, or even without the home directory set up. I was wondering if maybe (luckily and convieniently) adduser had an option for easy pop3 user set-up, but i didn't find any, then i thought that maybe i'd make a shell script to do all the restrictions automatically. I was also wondering if anyone knew how to do that check first/send after bit where users must first check their pop3 mailboxes before using the SMTP server to send mail out (i want to prevent just anyone from the internet from using the SMTP server). Any more comments/suggestions would also be greatly appreciated.

Complete hard-drive crash!
Hello! Hi everyone, i was under the impression that FreeBSD had great hard drive reliability even when using Soft Updates. I'm sure it does as nothing like this has ever happened to me before. I'm using FreeBSD 4.8 Release with a custom kernel (nothing questionable taken out) with the packaged version of KDE 3.1.0 that comes on the dist CD. I've been using it very stably for about a month and a half now (less than zero problems) and today i opened Konqueror and my computer HARD FROZE, super hard. Since most of my files are backed up daily i wasn't worried, and usually with freezes not many files are lost, if any. Well when i rebooted after the freeze my hard drive lost it's MBR i guess (or maybe it got corrupted) because my bios gave me NON SYSTEM DISK OR BOOT ERROR. I rebooted once more after that, and the FreeBSD bootloader came up (slower than usualy) and slightly complained about not findind loader.conf. Then it attempted on loading the kernel, until the kernel finished loading (stopped printing devices) and gave me a prompt and asked me what root device i shoudl load ( it was in the form of fstype:device) i attempted ufs:/dev/ad0s1a but it named a bunch of errors and i was forced to reboot into the same process again and again. So i fsck'ed alll my partitions that were mounted when it first crashed (using FixIt) and i was able to get all my files back. The problem is the files were scattered throughout each partition in lost+found and some folders were just gone, so the filesystem, i think, is completely ruined. I was using Soft Updates for all my partitions besides the root partition (even though the root was also missing a lot of files too). I wanted to know what could have caused my hard drive to crash so hard and also how i could avoid this type of behavior in the future because as it looks i might have to do a complete reinstall. Also, How can i reinstall the FreeBSD standard MBR? (the one that is minimal and only loads FreeBSD). Thanks a ton! -rian _ Add photos to your e-mail with MSN 8.
