CheckResolv
===========
This is a quick and dirty hack, built for chasing
a LPRng latency problem. Usage is very simple:
you give a hostname or an IP addr, and the soft
try a few lookup and/or reverse lookup.
Options are:
-V display version
-r do a reverse lookup
-v increase verbosity
-e print relateds env vars
-t display time op operations
Have a good life, don't release CO2 in the Ternet...

.TH CheckResolv 1 "2005 September" "various OS" "Tonton Th"
.SH NAME
checkresolv \- quick & dirty tool for checking sanity of resolver.
.SH SYNOPSIS
\fBcheckresolv\fP -V
.br
\fBcheckresolv\fP [options] host.name
.br
\fBcheckresolv\fP [options] 42.51.69.406
.SH DESCRIPTION
CheckResolv is a (not so) q'n'd tool for checking basic capacities and
potentials bugs of your resolver configuration.
I have started the dev of this thing when I was working hard on a remote
nasty printing problems.
It use only \fBgethostbyname\fP and \fBgethostbyaddr\fP functions,
like any lambda applications.
CheckResolv can also display environment variables who can modify the behaviour
of this damned resolver, or give you some problems.
.SH OPTIONS
.B -V
display version number and exit.
.br
.B -h
brief help on the command-line options.
.br
.B -v
display various useless messages.
.br
.B -r
do reverse lookup on IP address discovered.
.br
.B -e
show content of a few environment vars resolver-related.
.br
.B -t
compute elapsed time of operation, not really accurate.
.SH TIPS
If you have a strange problem between two hosts, "don't panic". Take the time
to compil CheckResolv on the two hosts, and run it with the -r option, first
with the hostname, and after that, with the IP address.
And do this two runs on the two hosts. So, you get four results.
Now, use your brain...
.SH CONFIG FILE
All your config files are belong to us. In the futur, may be you can
put a list of env vars to display in a file.
.SH ENV VARS
If the environment variable CHECKRESOLV is set to "tech", reverse lookup
and timing are activated, very nice when your pop3 server take 42 seconds
before you can get some silly answer.
And "all" give you all the bells & whistles.
This variable override command lines options.
.SH SEE ALSO
.BR resolver (5),
.BR host (1),
.BR dig (1),
.BR nslookup (1)
.SH BUGS
Some are here, some are waiting in the dark. Hidden static storage is a pain.
No IPv6 support. No Slackware package, no Debian package...
.SH COMPILATION
Currently (2005 march), this software was only tested on Slackware 10.0 and
Debian Sarge, but it can
compile 'fine' on others Linux or *BSD flavors. IRIX is also a valuable target,
because my troll-master use it...
.SH AUTHOR(S)
Thierry (aka tth) Boudet, with help from @donis, Miod, Reynerie...

.TH ClearGDBM 1 "Juillet 2002" "GNU/Linux" "tontonTh tools"
.SH NAME
cleargdbm \- Videur de fichiers GDBM
.SH SYNOPSYS
\fBcleargdbm\fP -V
.br
\fBcleargdbm\fP -h|-?
.br
\fBcleargdbm\fP [-v] fichier.gdbm
.SH DESCRIPTION
Les fichiers GDBM permettent de stocker des 'tables associatives'
sur mémoire permanente. La rapidité de lecture de ces tables est
impressionante. Je les utilise parfois comme cache de bases de
données dans des applications Web.
.br
\fBcleargdbm\fP permet de 'vider' une table gdbm, en fait de l'effacer
physiquement du disque, puis de la re-créer sans rien y mettre dedans.
Accessoirement, on peut aussi mesurer la vitesse d'utilisation, de
manière totalement arbitraire (à la BogoMIPS, en fait).
.br
Le programme tente de préserver certaines caractéristiques du fichier
destroyé: les droits d'accès uniquement à l'heure actuelle.
.SH OPTIONS
.B -V
pour connaitre la version du machin-bidule.
.br
.B -v
pour avoir du bavardage (fmbl roulaize) sur ce que fait ce kludge.
.br
.B -h -?
Ah, il y a un peu de l'aide. On va en avoir besoin.
.br
.SH SEE ALSO
.BR gdbm (3)
.BR GDBM_File (3pm)
.BR dumpgdbm (1)
.SH BUGS
Il y en a probablement quelques uns qui trainent...
Au lieu de raler, il faut signaler les problêmes à l'auteur.
Toutes les idées d'amélioration sont les bienvenues.
De bonnes bouteilles aussi.
Bières anglo/saxonnes (Guinness roulaize) ou vins languedociens.

.TH DumpGDBM 1 "Fevrier 2003" "GNU/Linux" "Oulala tools"
.SH NAME
dumpgdbm \- Dumpeur de fichiers GDBM
.SH SYNOPSYS
\fBdumpgdbm\fP -V
.br
\fBdumpgdbm\fP -h
.br
\fBdumpgdbm\fP [-vxoa8] [-m 42] [-i] fichier.gdbm
.SH DESCRIPTION
Les fichiers GDBM permettent de stocker des 'tables associatives'
sur mémoire permanente. La rapidité de lecture de ces tables est
impressionante. Mais leur utilisation est parfois surprenante.
Par exemple, la présence ou non d'un '\\0' en fin de chaine...
.br
\fBdumpgdbm\fP affiche en ascii, en octal, ou en hexadécimal les
couples (clef/valeur) contenus dans un fichier GDBM.
Il devrait contenir bientôt (ymmv) un mécanisme de détection des clefs nulles,
réputées pour créer des problèmes dans des langages à typage faible,
comme Perl ou PHP. Suggestions attendues...
.SH OPTIONS
.B -V
pour connaitre la version du machin-bidule.
.br
.B -x
affichage des octets en hexadecimal.
.br
.B -o
affichage en octal (pdp11 roulaize).
.br
.B -a
affichage en ascii (voir aussi -8)
.br
.B -v
pour avoir du bavardage (fmbl roulaize)
.br
.B -h
ah, il y a un peu de l'aide.
.br
.B -8
C'est OK pour afficher les caractères dont le code ascii > 128.
.br
.B -m 42
détermine le nombre maximum d'octets affichés.
.br
.B -i
démarrage en mode interactif.
Les options -x, -a et -o sont exclusives et c'est la dernière rencontrée
sur la ligne de commande qui a la priorité.
L'option -8 n'a de sens qu'en mode ascii.
.SH INTERACTIF
Pour le mettre en oeuvre, c'est l'option
.B -i
au lancement, et ensuite, au prompt, un
.B ?
pour une liste abrégée des commandes. Puis taper:
.B help command
ou
.B listcom
pour en savoir un peu plus. Désolé, mais mon interpréteur de commandes n'est
pas (encore) parfait. Il utilise readline, mais ne sauvegarde pas (encore)
l'historique des commandes.
Les commandes de recherche,
.B ds
et
.B ks
, utilisent les expressions régulières POSIX.
.SH SEE ALSO
.BR gdbm (3)
.BR GDBM_File (3pm)
.BR cleargdbm (1)
.BR regex(3)
.SH BUGS
Il y en a probablement quelques uns qui trainent...
Par exemple, rien n'est encore prévu pour l'EBCDIC (Flo?).
Mais bon, au lieu de raler, il faut signaler les problêmes à l'auteur.
Toutes les idées d'amélioration sont les bienvenues.
De bonnes bouteilles aussi.
Bières anglo/saxonnes (Guinness roulaize) ou vins languedociens.
.SH SORRY
I have to rewrite this man page in english, but my english is very poor.
.SH LICENSE
Ce logiciel est distribué sous la bienveillante protection de la
GNU GENERAL PUBLIC LICENSE, version 2. J'en profite pour remercier
.B RMS
sans qui rien de tout ça ne serait arrivé.
.SH AUTHOR
Thierry Boudet (oulala@chez.com) depuis Juillet 1999.
Pour en savoir plus: http://krabulator.free.fr/devel/ ou
http://tboudet.free.fr/
.SH DEDICACE
Euh, donc ce logiciel est dédié à Jennifer Mack, dont je suis un fervent
admirateur depuis très longtemps. Merci également à Joshua, qui m'a fait
découvrir que tout cela n'est qu'un jeu.

.TH HexDiff 1 "November 1905" "Divers Un*ces" "TontonTh tools"
.SH NAME
hexdiff \- un 'visuel diff' pour les fichiers binaires
.SH SYNOPSIS
\fBhexdiff\fP -V
.br
\fBhexdiff\fP -h|-?
.br
\fBhexdiff\fP file1 file2
.SH DESCRIPTION
\fBhexdiff\fP a été crée pour faciliter le débuggage de routines d'écriture
de fichiers images (PCX et BMP, comme par hasard). En comparant un fichier
kimarche et un fichier que je fabrique, ça va aider :)
.br
\fBhexdiff\fP affiche, après le lancement, deux fenètres montrant un dump
hexadécimal et ascii du début des deux fichiers. Deux barres d'état
donnent le nom du fichier, sa taille et l'offset courant.
La fenêtre courante est marquée par '**' à gauche de l'écran.
A l'aide de diverses touches du clavier, vous pouvez vous déplacer
simultanément dans les deux fichiers, et le dump vous montrera alors,
en vidéo inverse, les octets qui sont différents entre les deux fichiers.
Après, hein, c'est à vous d'interpréter...
.SH OPTIONS
.B -V
Pour connaitre la version du machin-bidule.
.br
.B -h | -?
Ah, il y a un peu de l'aide. Bon à savoir.
.br
.B -X
Help for debugging your ~/.hexdiffrc, or the rc file parser.
.SH KEYBOARD COMMANDS
.B x q
Quitte le programme. Parfois...
.br
.B u j U
Remonte d'une ligne (de 16 octets), ou de quatre, dans les deux fichiers.
.br
.B d k D
Descend d'une ou quatre lignes dans les deux fichiers.
.br
.B <space>
Descend de plusieurs lignes dans les deux fichiers. Ce nombre étant calculé
selon la taille de l'écran, je ne peux le révéler ici.
.br
.B 0 <home>
Reprend au début des deux fichiers.
.br
.B $
Vous emmène aux environs de juste avant la fin du plus petit des deux fichiers.
.br
.B g
Propose de saisir un nouvel offset pour les deux fichiers. Attention, cette
fonctions a été écrite à la 'Gruik' et n'est donc pas fiable.
.br
.B H
Bascule l'affichage des offsets entre le décimal et l'hexadécimal. Le mode
initial est configurable.
.br
.B i
Affichage des informations 'fstat' sur le fichier sélectionné.
.br
.B I
Affiche les mêmes informations, mais pour les deux fichiers simultanément.
.br
.B A
Open the (currently) experimental AsciiViewer.
Maybe coredump with no request. <tab> switch as usual.
.br
.B ^O
Ouverture d'un nouveau fichier dans la fenêtre courante. Le "selecteur de
fichier" est encore rudimentaire. Utiliser 'Q' pour annuler, <Enter> pour
valider, et '?' pour l'aide.
.br
.B n
Part à la recherche de la prochaine différence entre les deux fichiers.
.br
.B <tab>
Change la fenètre active. Pour le moment, ça ne sert presque à rien.
Ah, non, il parait que ça joue sur le contexte d'autres fonctions.
Personne ne m'en a parlé, je ne suis au courant de rien, alors
je --->[]
.br
.B ?
"Popupe" une fenètre d'aide reprenant les principales commandes. Pour
les autres commandes: un seul slogan, Utsl.
.SH CONFIG FILE
Le fichier de configuration est
.B .hexdiffrc
et doit se trouver dans le
.B $HOME
de l'utilisateur.
Une ligne commençant par un
.B '#'
est un commentaire. Les lignes vides sont ignorées. Pour plus de détails,
consulter le fichier 'hexdiff.rc' qui devrait se trouver dans l'archive.
.SH SEE ALSO
.BR diff (1),
.BR cmp (1)
.SH BUGS
Si vous redimensionnez votre xterm, \fBhexdiff\fP se prend un SIGWINCH,
et s'en va probablement visiter le pays des Slashies. Dans la pratique,
il en revient très vite.
.br
L'affichage en fin de fichier, si les tailles sont différentes, est
parfois un peu déglingué. Mais je vais réparer ça.
.br
Cette page de man n'est pas synchrone avec la réalité virtuelle du code.
Car le code évolue plus vite que la réalité. Parfois.
