Ahojte

Chcem prepojiť dva stroje, hlavne kvôli sťahovaniu súborov z jedného na druhý. Na jednom stroji mám Ubuntu 10.04 a na tom druhom Lubuntu 10.04. Chcem to spraviť cez server alebo SSH alebo Apache, ale neviem moc ako na to, so sieťami som menej pokročilý. Oba servery mám úspešne nainštalované, len neviem, ktorý by bolo pre mňa jednoduchšie vybrať. Apache používam väčšinou cez balík XAMPP, ten originál v systéme keď robím stránku zvyknem vypínať. Prosím, odkážte ma na zdroje, ktoré by mohli byť nápomocné (prosím vás, len nie na 1000 stanovú dokumentáciu v PDF, tú si nájdem, keď budem trošku pokročilejší). Stroje mám zosieťované cez wi-fi router. Súbory chcem zdieľať cez HTTP alebo FTP protokol.
Díky

Administrátor

Nainstalujes server, napr. Apache pre HTTP (inac, XAMPP a podobne balicky su IMHO zlo, v Ubuntu mas Synaptic alebo tasksel, tam je vyber balickov pre LAMP server otazkou par kliknuti), proftpd pre FTP, ak ti bezi, natukas na druhom pocitaci IP adresu (vo vnutornej sieti, 192.168.nieco, zistis z ifconfig) a hotovo.
Inac, ak potrebujes tie subory iba sharovat a nechces ich mat duplom, mozes pouzit NFS.

Užívateľ

Tak som to skúsil. Hodil som si aj proftpd. IP adresu som úspešne pingol, ale keď som ju zadal do prehliadača, nič sa nedialo. Inak, ten ifconfig nemám šajnu, kde mám hľadať. Prosím ťa, napíš mi adresárový strom.

Administrátor

Do prehliadaca? A nezabudol si na ftp:// protokol? Resp. teda pockaj, no, instaloval si len proftpd alebo aj Apache?
Spusti si na pocitaci, na ktorom bezi server, terminal a zadaj `telnet localhost 21`. Ohlasi sa ti server, ze bezi (stavovy kod 220)?
Program ifconfig je v /sbin.
Este teda aby sme si to ujasnili, s Unixami si ako-tak rozumies?

Užívateľ

kód:

andrej@andrej-laptop:~$ telnet localhost 21
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.
andrej@andrej-laptop:~$

Mám nainštalovaný a spustený aj Apache, aj proftpd.

S Linuxom mám asi 3 ročnú takmer každodennú prax, takže celkom v pohode, ale do sietí som lama.

Aha, jasnéééééé. ifconfig.

Ty kokso. Už si spomínam. Ja som si myslel, že je to nejaký konfigurák.

Administrátor

Jaj, no dobre, tak nechajme proftpd tak, s Apachom som robil castejsie a mal by fachcit okamzite po instalacii, tak to bude snad lahsie. Restartuj Apache, nech vidime, ci to nehadze chybove hlasky - ako root `/etc/init.d/apache2 restart`, potom vytukaj http://localhost v prehliadaci a napis, ci to zobrazilo It works. Vsetko robis na tom pocitaci, kde je nainstalovany server, siet este neriesime.

Užívateľ

V pohode. "It Works" svieti. S localhostom nemám najmenší problém. Len progblém mám dostať sa z jedného počítača na druhý, na ktorom ten Apache beží.

Administrátor

Coze, neverim. Ukaz, ako citas adresu z ifconfig, aby sme si boli isti, ze natukavas adresu spravne. S iptables si sa nehral? Ked si sadnes za druhy pocitac a ako root skusis `nmap ip.servera`, co ti to vypise?

Užívateľ

ak to chces na sharovanie nebude pre teba lepsia samba?

Užívateľ

Vípis z nmap na klientskom stroji:

kód:

andrej@andrej-desktop:~$ sudo nmap 192.168.0.169
[sudo] password for andrej:

Starting Nmap 5.00 ( http://nmap.org ) at 2012-02-06 15:16 CET
All 1000 scanned ports on 192.168.0.169 are filtered
MAC Address: 00:1E:4C:01:3B:B1 (Hon Hai Precision Ind.Co.)

Nmap done: 1 IP address (1 host up) scanned in 28.10 seconds
andrej@andrej-desktop:~$

Nie, nechcem sharovanie. Chcem Apache. Ide mi o niečo iné, ako sharovanie.

S iptables som sa pokiaľ dobre viem, nehral.

Idem teraz preč, takže teraz príspevky odomňa nesledujte. Zajtra alebo možno ešte dnes večer sa k téme vrátim.

Administrátor

Ukaz schvalne vypis z ifconfig na serveri.

Chlapci nechcem sa vtierať, ale napadlo vás niečo?

Fajn, takže aby sa nepovedalo, že som spal a sám som sa o nič nepokúsil, skúsil som pre testovanie účely kvôli vyriešeniu problému zmeniť rolu klietnského počítača na server. Išlo to dobre. defaultná localhostová stránka servera sa na ďalšom počítači natiahla, takže spojenie bolo úspešné, len som nevyrišeil, ako prenášať súbory. Ozaj, môžno by pomohol výpis konfiguračného súboru apache2 počítača, na ktorom sa mi server riadne rozbehať nedarí:

kód:

#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log"
# with ServerRoot set to "" will be interpreted by the
# server as "//var/log/apache2/foo.log".
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
ServerRoot "/etc/apache2"

#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
#<IfModule !mpm_winnt.c>
#<IfModule !mpm_netware.c>
LockFile /var/lock/apache2/accept.lock
#</IfModule>
#</IfModule>

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 15

#
# DefaultType is the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value. If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
DefaultType text/plain

#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
#
ErrorLog /var/log/apache2/error.log

#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
