Squid + Iptables + Udostępnianie Neostrady

etz257 · Kwiecień 10, 2006

Witam!

Wiem że temat dość często się przewija, ale pewne rzeczy są przestarzałe, a inne nie do końca jasne.

Sam próbowałem dojśc do pewnych rzeczy ale z braku czasu nie mam okazji zagłębic sie w temat a chciałbym dośc szyko skonfigurować moją FC5.

Więc tak:

1. Czy znalazłby się ktoś kto by ładnie napisał od początku do końca jak skonfigurować firewalla, tak aby system był bezpieczny i udostepniał internet.

2. Do tego by się przydała ładnie opisana konfiguracja squid'a, tak aby był "przeźroczysty" i służył komputerowi na którym jest zainstalowany i temu któremu jest udostepniane łącze.

Mam nadzieje że nie zagmatfałem za bardzo:)

Ja osobiście uzywam Neostrady i udostepniam net przez eth1, w FC4 poszło mi bez wiekszych problemów i myślałem że na FC5 też sobie szybko poradzę ale narazie na drugim kompie neta nie mam.

Brakuje mi w FC5 w Iptables zakładki zaufanych urządzeń. W FC4 było to i udostępnianie neostrady poszło bez problemu.

Moją konfiguracje SQUIDA przedstawiam poniżej, może ktoś sprawdzi i poradzi czy coś jeszcze zmienić, no i nie włacza mi się przy starcie systemu SQUID

#
#	If your peer has configured Squid (during compilation) with
#	'--enable-icmp' that peer will send ICMP pings to origin server
#	sites of the URLs it receives.  If you enable this option the
#	ICP replies from that peer will include the ICMP data (if available).
#	Then, when choosing a parent cache, Squid will choose the parent with
#	the minimal RTT to the origin server.  When this happens, the

#
#Default:
# reload_into_ims off

#  TAG: always_direct
#	Usage: always_direct allow|deny [!]aclname ...
#
#	Here you can use ACL elements to specify requests which should
#	ALWAYS be forwarded by Squid to the origin servers without using

#	local servers ignoring any parents or siblings you may have use
#	something like:
#
#  acl local-servers dstdomain my.domain.net
#  always_direct allow local-servers
#
#	To always forward FTP requests directly, use
#
#  acl FTP proto FTP
#  always_direct allow FTP
#
#
#	NOTE: This directive is not related to caching. The replies
#	is cached as usual even if you use always_direct. To not cache
#	the replies see no_cache.
#
#	This option replaces some v1.1 options such as local_domain
#	and local_ip.
#
#Default:

#
#Default:
# maximum_single_addr_tries 1

#  TAG: retry_on_error
#	If set to on Squid will automatically retry requests when
#	receiving an error response. This is mainly useful if you
#	are in a complex cache hierarchy to work around access
#	control errors.
#
#Default:
# retry_on_error off

#  TAG: snmp_port

#  TAG: coredump_dir
#	By default Squid leaves core files in the directory from where

Brakuje mi w FC5 w Iptables zakładki zaufanych urządzeń. W FC4 było to i udostępnianie neostrady poszło bez problemu.

Sorki, że ja się wtrącę OT, ale gdzie w iptables są zakładki? Przecież to polecenie wydawane z poziomu powłoki, to gdzie tam są jakieś zakładki? Może miałeś zainstalowany jakiś program ułatwiający ustawianie iptables. Coś w rodzaju firestarter, shorewall czy fwbuilder.

Pozdr,

Nie nie stawiam serwera! Chce tylko żeby mi śmigał szybko net na moim kompie i na tym któremu udostepniam łacze a SQUID wydaje się idealny do przyspiesenia neta

No i co do Firewalla to wiadomo przydalo by się żeby komputery byly bezpieczne, ale jak narazie to na tym drugim kompiem mam neta ale tylko jak u mnie jest XP właczony

To co nikt się nie pokusi coś napisać?

"To co pomorzecie? No pomorzecie!"

Wciąż mam problem z udostepnieniem netu Help!

yoda6886 · Kwiecień 13, 2006

jezu czlowieku o tym jest multum naprawde multum w sieci. najpierw udostepnij sobie net bez squida. to jest trywialne. jak to bedziesz juz mial, przeczytasz jak sie odpala i konfiguruje squida z www.squid-cache.org i jak dalej cos Ci nie bedzie chodzilo to napisz.

firewall - zainteresuj sie iptables -> o tym jest chyba najwiecej materialow dotyczacych (_linuxa_ → Linuksa) ORT w sieci...

ludzie google nie boli. nie robcie z siebie ciot.

Witam poraz kolejny.

Szukałem grzebałem ustwaiwałem i dalej nic

Skorzystałem teraz z tego postu i dalej nic http://forum.fedora.pl/index.php?showtopic...914&hl=iptables

Moge dodać że wyłączając firewalla net śmiga że hej ale po właczeniu tylko pingi dzialają

Juź opadam z sił na FC4 śmigało a tu cos nie che ruszyc

Dotarłęm również do informacji takiej:

Komenda echo 1 >/proc/sys/net/ipv4/ip_forward nie działa w FC 5

trzeba zmienić:

/etc/sysctl.conf

net.ipv4.ip_forward = 1

i nic nie dało.

tu http://forum.fedora.pl/index.php?showtopic=10220&hl=

ktoś ma podobny problem i też chyba nie rozwiązał

Dodam jeszcze że SELinux mam tez wyłączony. I nie wiem co się stało ale nie widzę w otoczeniu sieciowym kompa na którym jest Linux.

Ma ktoś jakis pomysł?

Pozdrawiam

Witam serdecznie i pozdrawiam wszystkich równie serdecznie.

Miałem podobny problem co Ty - kilku kompikom udostępniałem neta z mojego (i też korzystam z X'ów), w squidzie Ci nie pomogę bo go po prostu nie stawiałem - szkoda mojego czasu, a przyspieszenie w małych sieciach nieznaczne (czasem nawet zwolnienie).

Biłem się z moją gotową konfigurką która pięknie śmigała i w Mandarynkach (10.0, 10.1 i 2006) potem bez zmian również na Reksiu 10.1 (Aurox) Fedorce 2 i 4 a potem na Reksiu 11.1. Po postawieniu FC 5 klapa. Efekt identyczny - pingi są a firewall nie przepuszcza, już myślałem, że mam zainstalowany jeszcze jakiś pakiet zabezpieczeń.

Problem rozwiązałem następująco:

moja dotychczasowa konfigurka (dopięta np. do /etc/rc.d/rc.local)

echo "1" > /proc/sys/net/ipv4/ip_forward
/sbin/route add 192.168.0.3 eth3
/sbin/route add 192.168.0.4 eth2
/sbin/route add 192.168.0.2 eth1
/sbin/iptables -t filter -A FORWARD -s 192.168.0.0/255.255.255.0 -d 0/0 -j ACCEPT
/sbin/iptables -t filter -A FORWARD -s 0/0 -d 192.168.0.0/255.255.255.0 -j ACCEPT
/sbin/iptables -t nat -A POSTROUTING -s 192.168.0.0/255.255.255.0 -d 0/0 -j MASQUERADE
/sbin/modprobe ip_conntrack
/sbin/modprobe ip_conntrack_ftp

ku ścisłości - eth3, eth2, eth1 - to odbiorcy netu ode mnie - moje okno na świat - wlan0

W tej konfiguracji miałem tak samo - po zdjęciu firewalla - net śmiga, po założeniu - wraz z tymi klauzulami - nie.

W moim przypadku zbawienna okazała się linijka:

/sbin/iptables -I FORWARD -i ethx -o wlan0 -j ACCEPT

Mam nadzieję, że Tobie również to pomoże - pozdrawiam wszystkich serdeczniście

Jeśli chcesz aby usługa uruchamiała sie przy starcie to wpisz

chkconfig squid on - włączenia (off wyłaczenie)

jeśli chodzi o firewalla to w sieci jest strona z generatorem skryptu do tworzenia firewalla. Napisz do mnie [email protected] to ci przyślę ten skrypt
