Well, that's that idea buggered then.
If anyone knows how to get a 3Com Sportster ISDN TA External (
UK/European model, not the 128K US one ) to work under Linux ( it works

I'd expect there to be a "dhcp" package in the 5.2 distribution, but if
not, there's a great resource for binary RPM packages at rufus.w3.org, or
its mirror at userfriendly.net... check out

Who will volunteer to audit the entire netscrape source tree to verify that

Maybe you are, maybe you aren't, but with the netscrape executable being 13
megs I bet there's a hell of a lot we're both missing and that's why I
wouldn't count on it to provide any kind of restricted access to a guest
account.
Now if you can find some way to automatically delete and recreate the guest
account when the xdm session is logged out, that would be cool.

Hi Ian,
I noticed that just a few of my timestamps were 9 hours ahead of me, and since
I'm in Japan, 9 hours ahead of me is a time that doesn't yet exist anywhere in
the world. In fact, unless someone moves the dateline, it can never be 9 hours
ahead of me, anywhere, ever. ;-) (Nine hours *behind* me is GMT.)
Anyway, I pulled out the man page on advice from some folks, and used that
command above -- just as you have suggested for this other fellow. My system
clock is JST, by the way. But after doing that, I still get this on boot:
Jun 10 13:38:19 localhost kernel: Freeing unused kernel memory: 60k freed

As you see, there are about 13 lines out of the many which are wrong.
The actual boot time was 1:38 pm JST. At that time, there is no Jun 10 at
22:38 anywhere in this world. Where it's 22:38, it's Jun 8, not Jun 10. So,
what do you make of this, and how would you suggest attacking it?
One thing I notice is that the system clock gets set (see above) *after* these
invalid time stamps. But I sure don't know how to fix this.
Yuki ^_^

I was facing the same kind of trouble. I'm setting up a network between our
family's summer houses and the distance from my house to the central hub is
~120m. I called the local Black Box representative for a price on a repeater. It
was 2500FIM(~400US$)! A bit too much for a summer house. He said that UTP twisted
pair (10Mb) should easily do 150m, especially as I don't have any disturbing
factors except some screaming children ;-). Nice advice, especially as he did not
sell anything.

Subject: Dns problem
Date: Wed, 9 Jun 1999 22:11:06 +0200
I use 'sygate' for windows on a computer to connect my other computer to
internet. (a program that provides a gateway and a dns-server). The gateway
works just fine. But dns doesn't! (sygate is alright, but linux can't find
any host names).
Also when i try to ping MB (the gateway) it can't find the ip for MB. If i
ping 195.195.195.75 (MB) it works fine. If i ping 207.155.248.4
(ww.bleem.com) it also works
What do i have to put in my resolv.conf?

I just put together a PII 350 system with a 3com 905B Nic and Caldera Open
Linux 2.2. Everything is good so far. NIC works. My problem is this: I have
an ADSL internet service that uses dhcp. I followed the dhcp mini howto to
the letter. It did not work, I could not connect to the internet. Then I
tried the troubleshooting section of the mini howto and tried running
dhcpcd with the -r switch from a terminal window. That worked. But
everytime I reboot I have to open a terminal window and type that command.
The howto also said "If this solves your problem add the "-r" flag to the
boot up scripts ie. instead of /sbin/dhcpcd you will have /sbin/dhcpcd -r"
How do I do this? I tried to edit /etc/sysconfig/network-scripts/ifup
like it said, and I fouund a line that said something like .../sbin/dhcpcd
-HD... and I inserted the lowercase r in front of the HD and rebooted but
it still did not work. I sill have to manually enter dhcpcd -r for my
internet to work.
Please go easy on me as I am just learning Linux.
Thanks in advance

CableCom manufacture racks and accessories.
SynOptics and Hewlett Packard manufacture hubs in both SNMP-managable
and non-managable versions.
You should also invest in a UPS such as those manufacturered by APC.
I can highly recommend these products since I have installed and
configured these products during many contracts with the military and
other government departments and agencies.
I hope this will point you in the right direction.

Ah, that makes sense. It's annoying, but it makes sense :-)
I suppose another alternative is to go buy a name-brand NIC and use ne

I'll try your approach and let you know the results. I appreciate the

The hosts file on windows should be 'hosts'.

If you can ping them by IP number, You are on the right track.

You could just give an extremely limited PATH to the user who runs X. Just
Netscape and xinit. I think that would stop the telnet thingy. Anyways who
would allow telnetting in /etc/inetd.conf, if the machine is for a surf
station? Then I would use a windowmanager without the possibility to call
xterms or give commands directly. I think icewm could be configured to do
this. Then give only reading rights to all configuration items.
Oh and mount the /usr/ and /opt directories over the network.(NFS or SAMBA)
That way you can upgrade all software on one machine. If somebody manages to
crack his surf machine, he can't do a lot of BS there.
The first proposal (no WM) is not possible as Netscape itself opens up
several windows.
