Re: [PLUG] Accessing IP-dependent pages from home... 

*** NOTE: This bounced back from Nothing But Net, so I'm trying again... ***

[Warning: Long-winded ramble about routing follows. If you want to skip

Thanks for the long ramble - Very didactic, really. Now, I have pretty much made up my mind as to what I want:

a) Instead of setting up a proxy server, which will have all the problems pointed out by Bill, I think the easiest thing to do is just to set another IP for eth0 and then set up a table with static routes to the servers with the databases that goes thorugh the 10.1.x.x gateway. In that way, they'll beleive is from within the USP firewall and allow document downloads.

b) Then, users will have to a) log into tonga using telent, get their stuff with lynx, and then use fetch or whatever to get the documents to their home machine. Although navigating through text is sometimes aggravating, it will save a lot of time for those using dial-up connections.

Now, I'm still having problems making this work, and here is were I need help. First, the following command works:

/sbin/ifconfig eht0:1 10.1.20.30 up

When I try '/sbin/ifconfig' alone, I get:

eth0 Link encap:Ethernet HWaddr 00:A0:C9:93:31:4A
 inet addr:208.7.154.206 Bcast:208.7.154.255 Mask:255.255.255.0
 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
 RX packets:23132 errors:0 dropped:0 overruns:0 frame:0
 TX packets:465 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqueuelen:100
 Interrupt:11 Base address:0xe000

eth0:1 Link encap:Ethernet HWaddr 00:A0:C9:93:31:4A
 inet addr:10.1.20.30 Bcast:10.255.255.255 Mask:255.0.0.0
 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
 Interrupt:11 Base address:0xe000

lo Link encap:Local Loopback
 inet addr:127.0.0.1 Mask:255.0.0.0
 UP LOOPBACK RUNNING MTU:3924 Metric:1
 RX packets:60 errors:0 dropped:0 overruns:0 frame:0
 TX packets:60 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqueuelen:0

And '/sbin/route' gives me:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
208.7.154.206 * 255.255.255.255 UH 0 0 0 eth0
208.7.154.0 * 255.255.255.0 U 0 0 0 eth0
10.0.0.0 * 255.0.0.0 U 0 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 208.7.154.254 0.0.0.0 UG 0 0 0 eth0

Now, I also made a static-route file in /etc/sysconfig that looks like:

any net 216.200.143.20 netmask 255.255.255.255 gw 10.1.1.254
any net 216.143.112.80 netmask 255.255.255.255 gw 10.1.1.254
any net 198.81.200.2 netmask 255.255.255.255 gw 10.1.1.254
any net 209.67.7.112 netmask 255.255.255.255 gw 10.1.1.254

In any event, it's not working. According to a site I found that reports IPs, I'm still going out as 208.7.154.206, tonga's default address, which goes out through the wrong gateway...

Any ideas?

Thanks!

Guillermo
