[expert] Install Problem
I have been trying to install Mandrake 7.0, but it aborts in the second stage. A search of the list came up with the alternate screens accessed with Ctrl-Alt-F3 and -F4, but the information they show doesn't mean much to me. The Ctrl-Alt-F3 screen ends with: * method selection completed * state saved to /tmp * symlink /tmp/stage2 failed * second stage running * extra log messages enabled * running: insmod serial * warning: insmod serial failed at /usr/bin/perl-install/modules.pm line 358 * probing /dev/ttyS0 find class: * probing /dev/ttyS1 find class: Any ideas if that failed symlink is the problem, and why it would occur?

ping and tracert send out ICMP (raw IP) packets. It's my hypothesis that
root permissions are need to send or receive those.
As for su and mount, root permissions are needed under some or all
circumstances. The only way to do that is to run the application as root
(and switch the effective UID to the user if the extra permissions are not
needed).

I don't know for what reasons, but 90.0.0.x is guaranteed not to be routed, so it's not "just any old network". At least, that's what some old tool told me, and it happened to be the one to which I was introduced before 192.168.1.*. Like I said in my original post: "I don't remember what is usually used", meaning that it's not the one usually recommended. So everyone, use 192.168.1.*, not 90.0.0.* to be on the safe side! > Eric: I'm not trying to publicly toast you, I just want to make it clear > for other folks' benefit.

I just bought the hub last week, got the > linux machine working, and had no idea of the implications. Check the archives of the list, available on the mandrake site where you subscribed to the list. Assuming your ISP is providing you with only a single IP address, you want something along these lines: ++ | Comp B |---\+---+ ++\---| H | ++ +---+ | u |--| Comp A |-| Modem | ++/---| b | ++ +---+ | Comp C |---/+---+ ++ Comp A is your Linux box. The network card in A connected to your cable/xDSL modem is assigned the external address supplied by your ISP (static or DHCP). You'll need to use ipchains on this box so that it acts as a gateway for the LAN. Comp B and Comp C are you Windows or ther Linux boxes. The three network cards connected to the hub are assigned internal IP addresses. I don't remember what is usually used, but I use 90.0.0.1, .2, .3, etc. I don't know anything about linux security, so I can't comment on that area. ELB -- Eric L.

I don't believe that's the problem. The problems are security/privacy and bandwidth usage. Bandwidth: All internal packets are also being sent over to the ISP. This can cause performance problems. For example, if the LAN is 100Mbps and the connection to the world is only 1 Mbps, a transfer from one machine to another on the LAN will be limited to 1Mbps. Security: The ISP and possibly other clients can see your internal packets, and possibly even gain access to your private network. ELB -- Eric L. Brine | Chicken: The egg's way of making more eggs.

It could be there is more than one MIME type returned for PNG images. ELB -- Eric L. Brine | Chicken: The egg's way of making more eggs. [EMAIL PROTECTED] | Do you always hit the nail on the thumb?
