Subject: wierd BOOTP/DHCP problem
Date: Fri, 23 Jul 1999 14:53:17 -0700
I've been using HP-UX for BOOTP only serving until recently. I'm trying
migrate all of my IP address serving to a RedHat 6.0 server w/ dhcpd.
Everything under HP-UX bootpd works fine. When I try to boot some devices
(HP Printers w/ JetDirect cards mostly) they only get the IP address and
host name (no subnetmask, domain, etc.). The HP 8000 in the sample below
works fine. The HP 5SI in the sample dosen't. Anyone have any ideas?
Here's an excerpt from the /etc/dhcpd.conf file
subnet 192.168.252.0 netmask 255.255.255.0 {
option domain-name "mydomain.org";
option routers 192.168.252.254;
option ntp-servers 192.168.252.100, 192.168.252.108;
option domain-name-servers 192.168.252.100, 192.168.252.102;
option subnet-mask 255.255.255.0;
use-host-decl-names on;
}
....
group { # The Unix network
host jd-6a242e { # HP 5SI

Seems like one of the Raid versions does that. Kinda of like the Raid
where you have 2 hardrives in 1 machine on different channels, you can
also mirrow to a drive on an adjacent machine. There may be limit as to
how far the 2 boxes are apart. I haven't got to that yet. Just setting
up my second server with Raid 0 which will be my primary server, then I
will looking at doing what you are trying to do.
That would be a very convenient way to be able to maintain hardware etc
while the network is up.And in my business if 1 server went down for 15
minutes I would be behind at least all day.

Subject: start samba services on reboot

I'm using rehat 6.0 samba server. I'm the only one at work that knows
how to start the server or Samba.
If I'm out and the server tries to reboot, (like it did lately with an
extended power failure) then there is no one to start it all up.
Is there a way to have the server boot up , startx , start samba, start
the network services with no intervention?
Thanks (because I would like to have a vacation somewhere down the
road).

Subject: Re: Problems in configuring a dialout server using diald and IP masquerading
Date: Sat, 24 Jul 1999 08:27:01 -0400
I had a similar problem. The way I solved it was to _mostly_ ignore the
documentation about masquerading. Since the ppp connection was the only
access to the outside world, I did not need a firewall until the ppp
connection was made. So ipchains was the default ACCEPT for all three
main chains. Moreover, the resolv.conf file was did not exist except as
a symbolic link to another file that listed the nameserver for the lan
only.
Upon calling diald the link is changed to another file that does list
the ISP nameservers as well. This is done in the addroute script. The
ipchaining rules for the firewall, which essentially also enable
masquerading, are set by calling a script from the ip-up script--even
though the documentation states that it is non-blocking. Calling the
ipchains script for the addroute file did not work.
Of course, it still is not working quite right. I still get disconnects
often--but diald redials.
Hope this helps.

Date: Sat, 24 Jul 1999 12:37:18 GMT
Mike,
If I understand your post correctly, your default run level must be set to
3. If you want X (startx) to automatically startup at bootup, you need to
change the default run level to 5. This is done by editing the /etc/inittab
file and changing the following line from
id:3:initdefault:
to
id:5:initdefault:
Then as user "root" in an x terminal window, type: control-panel &
Invoke the run level editor button to enable/disable services at bootup.
i.e. add all the services you want to automatically start to run level 5
(smb, network, etc...). If you have anything custom that you want invoked
after the system has completly started (like ipchains), add those commands
to the end of /etc/rc.d/rc.local file.
If you want to test your changes before rebooting, type: telinit 5
Now... sit back, relax and take a vacation!!!

Subject: Network configuration advice
Date: Sat, 24 Jul 1999 09:10:01 -0400
I have a small network at home that is Windows based ( no
my-os-is-better-than-yours threads please).
Anyway, I've come to realize after a hacker attack that I need a firewall.
3 or 4 years ago I played around with Slackware and am familiar with it.
Not wanting to spend the big cash to set Windows up properly I decided to
put a Linux box between my network and the web. Then something occured to
me:
I have parts to piece together six computers. The primary system that I
rely on the most is a PII 333, 256M, 13 gig and a Voodoo3. Currently one of
the other systems is my PDC and Internet server. A third is an LCD luggable
that I usually use to read help files, tutorials, and misc. other jobs. The
others are basically just pieces and parts that I play with when I'm doing
network experiments etc.
I would like to set all of these systems up as multiboot with the PII as the
primary application server. I would also like to be able to use a boot
manager to boot into any configuration (Windows NT, 95, 98, Linux) from any
of the machines and have the kernels from all the the OS's on a single
machine.
I only have one ethernet card with a boot rom installed.
Is this possible? Is it advisable?
If so, what boot manager should I use?
Does anyone have a suggestion for a better configuration?

After a reinstallation of my Linux OS from the scratch (I use SusE 6.1), I
fail in establishing a ppp connection to my internet provider.
pppd tells me that it cannot find the script dialup.sh - I checked about
sixty five billion times - I spelled path and filename correctly
in /etc/ppp/options and all users have read and execute permission for the
script and all its parent folders.
What did I forget?

Good day all,
I am new to Linux, very new. I want very much to get into Linux, but,
it is kicking my A$$ all over town. I spent 1 month trying to use a god
damn WinModem when I finally found out it couldn't be done. OK - Fine
! This caused me to send back the network cards I had, and go with a
different strategy.
Heres the situation :
I am using a Dell optiplex 466/Le. It has a 4.3gb, and a 44x cdrom,
12mb. The rest is the usual. There are 3 ISA slots in the machine. In
one slot, I put an ISA Sound card, and in the other, I put a LinkSys
10bT card. Its a Home lan, what for would I need 100mb. Anyway, I have
as a client machine, a Dell 266, 32mb, 2 ISA, and 5 PCI. I Bought the
LinkSys Network Starter kit PCI, and put one of the PCI cards in the
Dell266, and I used the HUB that came with it to connect the two
computers.
For the life of me, I have been working most of my nights for 2 or 3
weeks trying to get them to talk to each other, with no luck. The
individual utilities that come with the cards both report that the cards
are working fine in each of the machines. The Dell 266 is running
Win95, and I believe I got the networking stuff done OK. On the Linux
side, I have tried to reinstall 6 times, going on 7. The Linux, first
of all seems to hang when I choose anything other than Custom Install.
And when it comes time to configure the card, none of the NE200 or Tulip
drivers I have heard about can detect the device in my machine.
I am completely at a lost and am now contemplating going to Win95 just
so I can get on with the business at hand.
Any help would be GREATLY appreciated !
Thanks, Nick

no, you have to install David Hind's PCMCIA package (I don't have RH 6.0,
but I'm sure it's included). The link will automatically get created when
you insert the modem (or on bootup, when cardmgr is started). Any pcmcia
card won't work if cardmgr isn't running. Check the PCMCIA howto.
good luck!
