I wish to connect using two different ISPs with the same LAN card ( if thats not possible then with two diff LAN cards) and want to use the bandwidth provided by both the accounts. How do I do this?
I created the interface eth0:1. So I do I login to both the accounts simultaneously ? There is just one command adsl-start. There aren't scripts like FC (ifcfg-ppp0 and ifcfg-pp1) in gentoo.
If I am able to connect to both the ISPs, will the following command allow me to use the bandwidth of both the accounts ?
ip route add default proto static scope global equalize nexthop dev ppp0 nexthop dev ppp1 |

If your gentoo is 2005.1 or current, then the easiest method of connecting two ISPs is to go out and purchase a 2nd ethernet card.
Edit /etc/conf.d/net
| Code: | iface_eth0="dhcp"
config_eth0={ "adsl" }
adsl_user_eth0={ "useraccountname@isp1.com" }
dhcpcd_eth0="-C -G -N -R -Y -o"
iface_eth1="dhcp"
config_eth1={ "adsl" }
adsl_user_eth1={ "useraccountname@isp2.com" }
dhcpcd_eth1="-C -G -N -R -Y -o"
iface_eth2="192.168.1.1 netmask 255.255.255.0"

Stick your passwords into /etc/ppp/pap-secrets file
then perform
| Code: | /etc/init.d/net.eth0 restart
/etc/init.d/net.eth1 restart |
If you want this to start up automatically at bootup, then ensure that rc-update records net.eth0 and net.eth1 by doing:
| Code: | ln -s /etc/init.d/net.eth0 /etc/init.d/net.eth1
rc-update add net.eth0 default
rc-update add net.eth1 default |

No, it would not give you the kind of load-sharing that you are (I'm presuming here) seeking.
Quick fix. Remove the word 'equalize' and use the word 'weight'.
The problem lies in two areas of IP networking principle:
1. Any server you talk to must expect a steady and fixed source IP address (yours).
2. TCP connection must maintain the same source IP address throughout its one TCP session (connection).
You want per-flow routing, not per-packet routing.
