Yes. That's the whole point, really -- X is supposed to make the OS
irrelevant. Telnet in, tell it where to send the display, enjoy.
Is freeBSD replacing the Windows box? I'm assuming the modem is on the
Linux box and the Win98 box is just a cheap X terminal. If I've reversed
their roles, please take what follows with a grain of salt.
>I launched netscape & it works although it is complaining about fonts.
I can believe that -- the X version of Netscape is not likely to be
optimized for a lowest-common-denominator Windows X server. In short,
running Netscape on the Linux box so you can view it under X on a
Win98 box is nuts, if you'll excuse my frankness. You can just as easily
use IP masquerade to push packets through the ethernet and run the Windows
version on the Windows box, using the Linux box to provide a "direct
connection" to the Internet. (No Windows Dial-Up Networking required.)
That way you get to use Windows fonts and features, such as they are, but
you still eliminate a layer of Microsoftian nonsense and get a smidgen of
Linux's stability in your connection. Better to push packets over your
Ethernet than entire formatted screens, IMHO.
>So where in netscape does one set it to access the net through win98
>(10.0.1.250)?
IP masquerade = Direct connection to the Internet = NO PROXIES. You'd put
the address of the Linux box (which has the modem) in Control Panel /
Networking / Ethernet card bound to TCP/IP / Gateway, and from then on all
your Internet apps on the Win98 box should "see" the Internet directly.
They don't know or care that there's a Linux box between you and your ISP.
See my Linux IP masq page, http://www.nic.com/~cannon/Linux/ for info on IP
masquerade and ppp dial-on-demand. It's gotten good reviews.

Well, I was referring to the stuff that pops up in the logfile when
the PPP daemon dials out. For example, on my machine:
Dec 26 15:00:17 furball pppd[1639]: pppd 2.3.5 started by root, uid 0
Dec 26 15:00:51 furball pppd[1639]: Serial connection established.
Dec 26 15:00:52 furball pppd[1639]: Using interface ppp0
Dec 26 15:00:52 furball pppd[1639]: Connect: ppp0 <--> /dev/modem
Dec 26 15:00:57 furball pppd[1639]: local IP address 209.47.93.65
Dec 26 15:00:57 furball pppd[1639]: remote IP address 205.150.233.65
If your nameserver's IP is the same as your 'remote IP', then I'm
guessing the defaultroute option is the problem. This was my original
suspicion, because without a defaultroute, looking up names wouldn't
work *unless* the remote IP was also the nameserver you use.

The kernel upgrade prolly did something to the PPP config then, though
I dunno why it would do that, and especially why it would remove the
defaultroute option.

You should be able to get away with sticking 'defaultroute' in
/etc/ppp/options, or as a parameter to pppd in the files you use to
connect (/usr/sbin/ppp-on, in my [very old] Slackware distribution).

Mmm, try running 'route -n' as root (no pun intended). Normally, with
PPP running, you should see at least two entries:
- one with 193.4.241.1 in the Destination field
- one with 'default' in the Destination field, and 193.4.241.1 in the
Gateway field
You might also notice one entitled 'loopback'; ignore it. I'm
guessing that of the above two entries, you have the first, but lack
the second, and that's the cause of your problem. I could be wrong;
if so, the only advice I can offer is to perhaps upgrade pppd to the
latest version.
Hope this helps! :)

Well, you send a quick response to my last post and in the meantime I fixed it
using completely different means. It turns out that I needed to *remove* the
IP number from the <namservers:> box in netcfg. I did that and all is well.
Go figure.
The other thing that was puzzling me was that I had already upgraded the kernel
and had been using PPP with it when it went wrong. I must have fouled netcfg
or something when I was fooling around trying to figure out some local
networking stuff.
Well, thanks again for your suggestions. I'm jsut glad it's working again.

Hi,
I've been trying to upgrade my Netscape Navigator 3.01 to some more
modern browser.
Tried Communicator 4.07 (from RedHat 5.2 RPM) and Communicator 4.5,
however both give me a NullPointerExcetion on trying to start the first
Java applet or trying to open Java console.
I also wonder where (or to be rhetorical why) the good old way of
enabling/disabling java or javascript changed; I cannot find the menu
for that on either browser.
Thankx for any help:

Same problem here, and as far I have seen it is a quite common one. I
haven't seen any solution around yet.
I have a 3c905b, under windows works perfectly; but under linux (I
have redhat 5.1) it gets recognized at boot, ifconfig reports it, etc,
all *apparently* in a perfect wat, except that when one tries to do
anything (like a ping), the thing seems dead.
I have seen that the harware compatibility list in the redhat site,
the 3c905"B" (as opposed to 3c905) is marked in boldface as NOT
supported.
Help!!!!!!!

I've been told to get one that does TCPIP. Is that all I need to worry

others? If one says it works with Unix, can I be sure it will be ok
