semi-long distance links
Hello! To make a network between 2 sites in a MAN or WAN the posibilities would be: - cabling (leased lines, fiber optic) - air waves (microwaves, ax25, packet...) - any provider providing the link via cabling or airwaves or satelite Wavelan/Orinoco cards can make a link about 15km. Which tecnologies are available to make a link of ~200 kilometers with speed at least 64kbps? Where can I find more info about this class of networks? Im looking for the tecnology not to get the service. -- Carlos Barros.

On all your hosts: route add default gw 194.226.7.1 or route add default gw 10.128.114.2.1 where corresponds. Second one: Specially if you can not change the cisco. on the firewall: in this order do eth1 = 194.226.7.9 eth0 = 194.226.7.9 # eth0 and eth1 have the same IP 194.226.7.9 rotue add -host 194.226.7.1 dev eth0 # do the same for all hosts that are connected to eth0 # and the trick is: for i in /proc/sys/net/ipv4/conf/*/proxy_arp do echo 1 $i done add 10.128.114.2.1 IP to eth1 do the masquerading for 10.128... net add firewall rules. on all hosts: route add default gw 194.226.7.1 or route add default gw 10.128.114.2.1 -- Carlos Barros. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

fore runner
Hello! Does anyone know the ForeRunner ES-3810 switch? I have a null modem cable(using only 3 cables) that I can use to connect to the console of a 3com switch but fore-runners. (using minicom) Is there something that i can play with? Things that I checked are: - 9600 8N1 - powered down and up and no message appears - enter does nothing. Sorry for the off topic, but couldnt find any help elsewere. Could you make them recognize more that 4 MAC per port ? Is there an easy(nice and gui) SNMP client (in debian)? -- Carlos Barros. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Is there any change that I have to do to the conf files? Is there a known problem?

LDAP on debian
Well, I don't know where to start. Well... There's someone who want to learn LDAP (ME :) Debian is using LDAP to authenticate users but I couldnt realize how it's done. The LDAP-guide is not well documented and I don't understand it very well... The first problem is to setup an LDAP server. How to use it, how to configure it. Then how to configure a host to use LDAP as the server to authenticate. I know there's pam-ldap and nss-ldap. But how d.org do that? I need the guidelines, for example, there's a lot of files in /etc/openldap/ which are in the ldif format? How does slapd run? I mean which files in the configuration dir uses? How to configure a database for the authentication purposes? How to add/remove entries in the database? When the configuration file change, how to update the running slapd server? Does LDAP has accounting? (like /var/log/wtmp?) I read a lot of the ldap-guide. Classes, persons attributes, but couldn't find a way to join each other with the authentication. I mean the interaction of the diferent parts do setup an LDAP-authenticated based network. Is there any HOWTO's Is there any text explaining how does it work? I mean The guide explain how to get, untar, configure, compile, install, run, change things, what it is, netscape... But nothing as to how the database must be for authentication purposes. -- Bye Carlos Barros.
A routing, source routing and masquerading with 3 networks
Hello! I need to masquerade a network only if the destination is some network and the source is one of the net In Debian frozen (to be released as potato) the configuration is this /etc/network/interfaces --- iface eth0 inet static address a.b.c.d network a.b.c.128 netmask 255.255.255.252 gateway a.b.c.129 iface eth1 inet static address net1a.net1b.net1c.129 network net1a.net1b.net1c.128 netmask 255.255.255.128 iface eth1:0 inet static address net2a.net2b.net2c.3 network net2a.net2b.net2c.0 netmask 255.255.255.128 up ip route add net1a.net1b.net1c.128/25 dev eth1 table 2 #default gateway for net2 up ip route add 0.0.0.0/0 via net2a.net2b.net2c.1 table 2 # now the rule to make net2 use routing table 2. up ip rule add from net2a.net2b.net2c.0/25 lookup 2 -- The net2 has a special condition that all packets that goes to a net3/24 must be masqueraded as if it goes from eth0 instead of going via net2a.net2b.net2c.1(eth1:0) The problem is that ipchains -A forward -j MASQ -s net2a.net2b.net2c/25 -d net3/24 does not do nothing. All packets are routed as the table says, so it does not masquerade. Kernel: 2.2.14 Can you giveme a clue how to solve that? -- Bye Carlos Barros.
