...ktory prideluje IP-cku podla MAC adresy.Mohly by ste pomoct??
A este by som potrebola nieco take, co zapisule prenesene MB z internetu-ale kontroluje to na kazdu IPcku zvlast.
teda napr. 192.168.0.22---stiahol 200MB
192.168.0.5 ---- stiahol 500GB

kazdy DHCP umoznuje pridelit IPcku podla MAC adresy. AK si pozres nejaky manual, urcite to najdes.
# dhcpd.conf
pridaj si tam napr. toto
host pocitac01 { hardware ethernet <MAC_ADRESA>; fixed-address: <IP>; }
kde MAC_ADRESA je napr v tvare 00:0e:a0:4e:00:01
a ip je 10.176.1.100
ako na to najdes v kazdom slusnom dhcpd manuale.
co sa tyka accountingu trafiku, prosim na kazdu otazku otvor new thread, pripadne si pozri diskusiu. |

dhcp server (pre *nixove systemy) najdes tu:
http://www.isc.org/sw/dhcp/
(inac byva sucastou takmer kazdej normalnej distribucie linuxu)
konfiguracia pre segment a jednotlivych hostov moze vyzerat nasledovne:
# dhcpd.conf
#
# Configuration file for ISC dhcpd (see 'man dhcpd.conf')
#
ddns-update-style none;
subnet 10.8.4.128 netmask 255.255.255.192
{
option routers 10.8.4.129;
option domain-name-servers 10.8.254.17, 213.215.72.6;
option netbios-name-servers 10.8.254.17;
option domain-name "localnet.sk";
range 10.8.4.164 10.8.4.167;
max-lease-time 3600;
default-lease-time 3600;
host HOST1 {
option domain-name "localnet.sk";
hardware ethernet 00:00:00:00:00:00;
fixed-address 10.8.4.130;
}
}
subnet 10.8.4.192 netmask 255.255.255.192
{
option routers 10.8.4.193;
option domain-name-servers 10.8.254.17, 213.215.72.6;
option netbios-name-servers 10.8.254.17;
option domain-name "localnet.sk";
range 10.8.4.232 10.8.4.235;
max-lease-time 3600;
default-lease-time 3600;
host HOST2 {
option domain-name "localnet.sk";
hardware ethernet 00:00:00:00:00:00;
fixed-address 10.8.4.194;
}
host HOST3 {
option domain-name "localnet.sk";
hardware ethernet 00:00:00:00:00:00;
fixed-address 10.8.4.195;
}
}
....
toto je maly vycuc z jednoho konfiguraku na jednom z mojich routrov, nechal som ti to aj s konkretnymi cislami aby si sa v tom (mozno) vedel lepsie zorientovat, len MAC a mena hostov som prepisal (z bezpecnostnych dovodov)
na prenesene data z netu ako tu uz jmi spomenul, sa da velmi rozumne pouzit iptables, ktore je vhodne este skombinovat s par scriptami a databazou, aby si neprisiel o hodnoty pri reboote  |

countre z iptables dostanes za pomoci parametrov -L -n -v -x
princip spracovania cisel je nasledovny (plati rovnako pre IN aj OUT)
$CUR = 'iptables ... so vsetkym oparsovanim'
$TOTAL = 'query na mysql databazu'
$PREV = 'query na mysql databazu'
if ($CUR < $PREV) //doslo k preteceniu countra
$TOTAL = $TOTAL + $CUR
else
$TOTAL = $TOTAL + ($CUR - $PREV)
endif
$PREV = $CUR
'zapis do mysql databazy hodnoty $TOTAL a $PREV'
Za pozvanie na veceru pre mna (autorky mam na svedomi shellscriptovu cast) a moju babu (ta zas spachala veci okolo mysql a php-ckove rozhranie na to aby sa to dalo aspon neak prezerat) ti to mozem komplet rozchodit |

| na ratanie dat mozes pouzit ntop (znacne obsiahle statistiky), alebo ip accounting http://ipaccounting.standus.com/ (jednoduxe, prehladne) prip si spravit nieco vlastne na ratanie dat |

Si: velmy pekne ti (vam) dakujem ze si taky ochotny ale mam taky pocit ze pouzijem radsej ten ip accounting,lebo cez iptables je toho na mna vela, a kedze niesom ziadny linux guru(a linuxom sa zacinam len zaoberat)-tak to bude lepsie riesenie,ale neboj tvoju snahu si cenim a ukadam si vsetky toje rady,a ked budem o nieco lepsi tak by som to chcel spravit cez ip tables a cez databazu MySQL.
Zatial diky! |

kedze pouzivam sickovu technologiu tu je priklad z dhcpd conf:
# dhcpd.conf
#
# Configuration file for ISC dhcpd (see 'man dhcpd.conf')
#
ddns-update-style none;
authoritative;
#siet 10.100.0.0/25 server 10.100.0.1
subnet 10.100.0.0 netmask 255.255.255.128
{
option routers 10.100.0.1;
option domain-name-servers 10.100.0.1, vonkajsia ip daka;
option netbios-name-servers 10.100.0.1;
option domain-name "volaco.sk";
range 10.100.0.96 10.100.0.103;
host nazovkompu {
option domain-name "volaco.sk";
hardware ethernet 00:00:00:00:00:00;
fixed-address 10.100.0.22;
}
.................................
................................
atd atd
a ako vie kade ma ist ktora ip? to uz nesuvisi s dhcp to urcujes s net ini skriptov ktory interfejs ma ktory rozsah
pr:
/sbin/ip a a 10.100.0.1/25 brd + dev eth1 |

magnum: vid to co ti tu napisal fleg, IP pre jednotlive sietove rozhrania sa prideluju v bootscripte (u mna standardne /etc/rc.d/rc.inet1) ktory vyzera asi takto:
#! /bin/sh
#
# file: /etc/rc.d/rc.inet1
# desc: network initscript
# created by SI
#ako sa to vlastne volam ? )
HOSTNAME=`cat /etc/HOSTNAME`

| A ako zabezpecit aby DHCP prideloval IPcky iba na jedno rozhrani? Mam konretne v routri 3 rozhrania - dve spojene s WiFi a na jedno je pripojena kabelazna siet v budove. Na WiFi rozhraniach IPcky pridelovat nepotrebujem - tam su nastavene staticky, ale v ramci kabelaznej siete v budove by som ich rad prideloval - a nemusia byt pridelene ani podla MAC |
