Captain's Log Supplemental

Life sucks when you expect a loved one to stick a knife in yoru ribs at any sec, got trop’d lightly, not what I expected but expected some thing to hit.

Dunno whats more fsck’d up, to think that she’d kill me, or worry she’ll get a stroke screaming.

To night I think I sleep armed, my prefered self defense weapon near by. (Light sabre for sword practice.) It’s got allot more punch and range then bare hands if I need to disarm some one in the dark, without getting injured.

I know I’m far from the perfect son, surly I’m rotton enough at times but I’m not a target to for some one to vent rage on for lack of a more appealing outlet to a problem (even if I’m related to the issue). Life is just, fsck, crap. I wish my family didn’t have such a knack for anger… sheesh I can’t hate some one for more then 10 seconds and if I want to hate longer then that I feel like a disgrace to GOD. These people, can thrive on it.

Anger, fear, hatred, a dark road. I reject it and all it stands for. Only one person has a right to take my life, and that is Jesus Christ and no one is beeting him to the punch imho. This war, is not one I asked for but it’s one I must stand warry to parry.

Note to self, prep a emg escape and evasion route, back woods might be good. I’d be blind as a bat but it’s thick enough to stop pursoot. Don’t think I’ll ever need it but it’s always good to plan for worst.

Well, just so I don’t forget if I frag it later heres the write process of my logging program (still working on).

It’s pretty simple, just get input till we get a return char, then write it into the file and append a newline. The only bugger is that the input has to fit into a char array of 256, any attempts to modify this to what is needed has returned junk pointer warnings in realloc at run time. I’m still a newb whose trying to learn the standard library and more so simple code is probably good.

if ((rflag < 1) && (tflag < 1) && (fflag < 1)) {
 char str[256];  /* this is enough space for our needs */
 fscanf(stdin, " %[^n]", str);
 fprintf(fp, str);
 fputc('n', fp);
 fclose(fp);
}

I figure one or two lines of text is what is most likly to be written to file, so str is big enough yet small enough for right now.

Un till I have the time, chance, and enegry to learn how to handle reading the file and printing it out to screen in a head/tail like fashion. I’m just having a system() call to invoke head or tail as needed on the file. /usr/src/bin/ cat, head, and tail are my current points of study for methods. Cat looks the easiest to follow but means I have to work on it when I have time to consintrate on the flow of the program.

This is also a test to see if the html pre tags work the way I’m hopping they do, since I don’t know allot of html to start with. It’s just never interested me very much [xhtml/css/php/e.t.c.]

I hate not being able to sleep…

My work load piles up, theres always more to do tomorrow then there is today. I usually have to be up early to walk the dogs and get them squared away before work. So sleeping in’s not a big option.

My mind always wonders about, from thought to thought it just can’t shut up. I can be thinking of any thing from a programming problem, a good movie, food (a killer), or even some thing more interesting. I don’t want to sleep because I don’t want to think all night, yet I want to sleep because I can’t go any further with my things to get done.

Theres got to be a better way………..

I did a custom install using only the base system and GENERIC kernel, later I installed the man pages rather then swap around. Partitioned the drive [ad0] into one large slice [ad0s1] with a 256MB partition for /var, a 256MB swap partition giving me 7.1GB for a root partition. I didn’t see a need to split /usr off of / on such a small system. It was cool not to have many packages installed after using PC-BSD and FreeBSD on my desktop. I quickly setup a text based web browser and cvsup tools via pkg_add.

pkg_add -r lynx
pkg_add -r cvsup_without_gui
pkg_add -r fastest_cvsup && rehash

I used fastest_cvsup to check what the best mirrors would be for getting a current copy of the system sources. Usually I’d just zip it over on a USB stick but my local tree was out of date.

fastest_cvsup -c us

tested all the US mirrors and showed me the fastest ones, I copied the example supvile over to my root directory and set the mirror. [#cp /usr/share/examples/cvsup/standard-supfile /root/]. A quick cvsup [cvsup -g -L 1 /root/standard-supfile] later and I was ready to update the machine. I checked out the make files, the FreeBSD handbook and the text files in /usr/src. I issued the make buildworld command and let her compile for about 5 hours. I then did a make buildkernel and it failed, I removed /usr/src and did a freash cvsup, tried again and failed again. Built a kernel using an alternate method discribed in compiling a custom kernel. Installed the kernel, dropped to single user mode and ran a make installworld. Life was good but the system still showed the wrong patch level, probably because the un updated kernel was running in memory 🙂
A reboot fixed that, tested things to make sure the system was working and no problems with commands not working right. The kernel was made /w sources downloaded a day after world. All was fine

rstf@.launchmodem.com-%uname -a
FreeBSD .launchmodem.com 6.1-RELEASE-p5 FreeBSD 6.1-RELEASE-p5 #0: Mon Sep 4 22:48:50 EDT 2006 root@.launchmodem.com:/usr/src/sys/i386/compile/GENERIC i386

I’ll setup hostname/custom kernel later and keep tabs of the security mailing list. Since then I have installed porteasy and the ports tree. I checked this link for some advice and isntalled gnu ghostscript via package, I checked on the ftp server to make sure I could get it without X11 support.

pkg_add -r ghostscript-gnu-nox11
I then built cups via porteasy -fb print/cups and took the night off.

I’ve still got to get back to setting up the printer but I’ve all ready begun on the configuration files. My primary goals for right now is to get the printer working and a custom kernel ready. Then I play with packet filter [pf the openbsd firewall] and tighting security. I’ll post more of my changes later since I have them logged.

Today I post a history and a log of my oldest computer here.

When one of my employers (who works in IT) found out I wanted to run FreeBSD but my mom wouldn’t let me repartition her computer (which we shared). He gave me an old office computer, keyboard, and monitor and I bought a Microsoft Basic Optical mouse for it. It gave me my first expirences with FreeBSD 6.0 and PC-BSD 1.0RC1-2. After PC-BSD made it’s 1.0 release, breaking upgradeability (via easy install patches) with the beta releases. After I got a new computer which runs XP and BSD, the machine sat more or less just for a way to quickly check system files or man pages when I needed to look some thing up.

After some time I tried installing NetBSD 3.0 on it, nice system but it just felt wrong after using FreeBSD/PC-BSD so much. So I overwrote it with a large install of FreeBSD. Just incase I might need to fall back to it I setup Xorg and Windowmaker. I wanted to set it up with Samba/CUPS so I could print form it and store some files on it. I never got a chance to finish samba config and the install burned most of the HDD. A few weeks ago I reformated with a bare bone install of FreeBSD 6.1-Release with the intention of learning more about system administration and security. System Specifications:

Model: Hewlett Packared Vectra Vli8 500
Processor: Katmai core, 500Mhz Pentium 3
Memory: 384MB DDR RAM
Storage: 8GB Maxtor IDE drive
Extra: 1 x CD-ROM drive, 1 x 3.5 1.44MB Floppy drive

I’ve been working on a logging program, it’s nothing much but it’s good learning fun, usually…

She basically deals with command line options like so:

while ((ch = getopt(argc, argv, "rchtf")) != -1)

        switch
(ch) {

        case 'r':

      
     rflag = 1;  
       
     /* read log, like tail */

      
     break;

      
     case 't':

      
     tflag = 1;  
       
     /* read top of log like head */

      
     break;

        case 'f':

      
     fflag = 1;  
       
     /* log to a diffrent file */

      
     break;

When ever a switch is “On” or “1” we perform an action. When no switches are given we fscanf stdin into a str[256] char array. This is more then enough space and shouldn’t be to memory hungry for right now. Input is taken until a new line is given then we store it in the char array and fprintf it into our logfile + a newline. I toyed around with trying to resize str to match stdin should str be to small, so we could avoid a segfault when trying to write huge entries. Yet allow no major limit on entry size. That nett’d me a good junk pointer warning I’m sure not able to find out all the details of.

Right now I’m working on trying to get the t switch working using the source for the head command as a reference. So far no real luck, we never get any output from it. It seems to break apart in the line of execuition so I know I’ve got to change things around.

I know I could just pass things along to head and tail via sh, but what is the fun in that? I’ll figure this out later must sleeeeeeeeeeeeppp!!!!

/* I don’t do HTML ! */

Ok time to inhale the manual

So far LJ seems a nice site, maybe I should replace my logging files with it. I’ll try to keep my blog orderly but I’m not the most structured person hehehehe.

Primary subjects: Computers, Programming, BSD and Unix like operating systems, trials and tribulations in my studies and learning of computers and technology. And life as a working schmuck and JNCO of one of the best Coop teams to ever play SWAT/R6.
