Program sshd (secure shell démon) je server pro ssh. Program ssh
nahrazuje programy rlogin a rsh a zajiÅ¡Å¥uje bezpeÄnou Å¡ifrovanou
komunikaci mezi dvÄma nedůvÄryhodnými poÄÃtaÄi pÅes nezabezpeÄenou
sÃÅ¥. Programy ssh a sshd jsou navrženy tak, aby jejich instalace a
použÃvánà bylo co nejjednoduÅ¡Å¡Ã.
Sshd je démon, který vyÅizuje spojenà klientů. NormálnÄ je
startován pÅi bootu ze souboru /etc/rc.local nebo jeho ekvivalentu.
Pro každé pÅicházejÃcà spojenà vytváÅà nový podproces.

#
# For more information about this file, see the man pages man(1)
# and man.conf(5).
#
# This file is read by man to configure the default manpath (also used
# when MANPATH contains an empty substring), to find out where the cat
# pages corresponding to given man pages should be stored,
# and to map each PATH element to a manpath element.
# It may also record the pathname of the man binary. [This is unused.]
# The format is:
#
# MANBIN pathname
# MANPATH manpath_element [corresponding_catdir]
# MANPATH_MAP path_element manpath_element
#
# If no catdir is given, it is assumed to be equal to the mandir
# (so that this dir has both man1 etc. and cat1 etc. subdirs).
# This is the traditional Unix setup.
# Certain versions of the FSSTND recommend putting formatted versions
# of /usr/.../man/manx/page.x into /var/catman/.../catx/page.x.
# The keyword FSSTND will cause this behaviour.
# Certain versions of the FHS recommend putting formatted versions of
# /usr/.../share/man/[locale/]manx/page.x into
# /var/cache/man/.../[locale/]catx/page.x.
# The keyword FHS will cause this behaviour (and overrides FSSTND).
# Explicitly given catdirs override.

gunzip -c /usr/share/man/cs/man8/sshd.8.gz zobrazuje krásně všechny české znaky. Když přesměruju výstup toho příkazu do souboru: gunzip -c /usr/share/man/cs/man8/sshd.8.gz > sshd.8 a prohlížím si ho příkazem less sshd.8 přímo, tak to nezobrazí obsah souboru (který obsahuje různé formátovací direktivy manuálových stránek apod.), ale zobrazí to přesně jako man stránku, a to stejným způsobem zmršenou (v podstatě se to chová ne jako less sshd.8, ale jako man sshd). Když ale dám cat sshd.8 | less, tak to zobrazí skutečný obsah souboru se správnými znaky a včetně direktiv, prostě doslova to, co je v souboru sshd.8. LESSCHARSET=utf-8 mám nastaveno.

INPUT PREPROCESSOR
You may define an "input preprocessor" for less. Before less opens a
file, it first gives your input preprocessor a chance to modify the way
the contents of the file are displayed. An input preprocessor is sim‐
ply an executable program (or shell script), which writes the contents
of the file to a different file, called the replacement file. The con‐
tents of the replacement file are then displayed in place of the con‐
tents of the original file. However, it will appear to the user as if
the original file is opened; that is, less will display the original
filename as the name of the current file.

Jinak ten vas pripad mi prijde trochu divny. Ja kdyz mam manualovou stranku v UTF-8, tak mi ji zmrsi nroff, protoze zadny vstupni preprocessing type
-mutf8 neumi (defaultni kodovani je totiz latin1). Naopak less se chova zcela korektne.
Kdyz se podivam do manualove strankym tak mi file rika, ze to neni v utf8

Dobre je take prozkoumat manual k nroffu
The nroff script emulates the nroff command using groff. Only ascii,
latin1, utf8, and cp1047 are valid arguments for the -T option, select‐
ing the output encoding emitted by grotty, groff’s TTY output device.
If an invalid or no -T option is given, nroff checks the current locale
to select a default output device. It first tries the locale program,
then the environment variables LC_ALL, LC_CTYPE, and LANG, and finally
the LESSCHARSET environment variable.
Bohuzel o vstupnim kodovani se nikde nedoctete. Podle mych zkusenosti nepatchovany nroff predpoklada iso-8859-1, pokud nepouziji makro (parametr -m) pre samotnym formatovanim.
1. v Makefile nastavit PREFIX (ja sem nastavil /opt/groff-utf8) 2. sudo make 3. sudo make install 4. v man.conf jsem nastavil NROFF /opt/groff-utf8/bin/groff-utf8 -Tutf8 -c -mandoc 5. vytvoril jsem si v /etc/env.d soubor 03groff-utf8 s obsahem PATH="/opt/groff-utf8/bin" 6. sudo env-update 7. source /etc/profile 8. man lsa vse se zobrazilo ok
Bohužel, vzhledem k tomu, že JSEM člověk LÍNÝ a POHODLNÝ, tak jsem zrušil všechno co jsem měl v utf8 a vrátil se k ISO-8859-2
Ale díky, určitě to jednou vyzkouším.
