You might also consider using the x3270-Terminal-Emulation for Linux, to
connect to the OS/390 (find it at
http://rufus.w3.org/linux/RPM/index.html). But this might not be an
option, since you are working at home.

At least under redhat, you allow yourself access to floppies by adding
yourself to the "floppy" group. You can allow users to mount devices using
the "user" switch in your /etc/fstab. pppd is fairly safe to setuid (at
least that's what I've been told). I do su to root to install, but *only*
for the make install phase, and usually only after I've seen what it will do
with make -n install.
I suppose a user could give themselves write access to /usr/local so they
can install software there without being root.
Another alternative is sudo, which will only query you for the password the
first time you run it (but will also time out after 5 minutes for safety).

You'll need bzip2 installed. If you do, see "bzip2 --help" if you don't,
get it at http://www.muraroa.demon.co.uk/
The command to unzip a bzip2-file is "bunzip2 <filename>".

Another thing you could do is check that you've got both Parallel Port
Support and PC-Style Hardware support options checked in the kernel
config.
When you type `dmesg | less` you should see entries like:
lp0: using parport0 (polling).
lp1: using parport1 (polling).
If you don't that means that your kernel hasn't seen the devices, for
whatever reason.

You can run some Windows apps under Linux using WINE
(http://www.winehq.com/) or you could take a look att VMWare
(http://www.vmware.com/) which lets you run Win95 in a virtual machine
at the same time as you are running Linux.

No, but I suppose it could still be useful for the menus. I suggest using a
minimal corner panel. One thing I found annoying is the panel produces an
appicon, so you have to set it not to have one. Hit ctrl-esc over the panel
(a little tricky) to set the attributes.

most of the time they do it to fill a need for themselves, not necessarily for a

for those people who do it for Linux they like it, if they didnt they woudln't be

no but most people who dont like it have a good reason to, mostly for the fact that
it doesnt' work like it should or doesn't allow people to do things like Linux
does. That and it costs an arm and a leg to buy MS shit, linux is free except for

You might also want to try Suse (what i'm running now) and Mandrake.
Mandrake is 110% compatible with RH. I heard it's easy to use. With
Suse, i had trouble updating the kernel :\ i may try Mandrake if it
doesn't work properly.

Hi everyone.
I've been using xawtv on my PII-400, RH5.1 Kernel 2.2.1, 64Mb RAM and
a Zoltrix TVMAX capturer. It runs smoothly but without sound. This must
be due to my SB64PCI audio card, but everything sounds except
this thanks to PCI and Ensoniq support on the new 2.2.x kernels.
I have tried things such as mute the sound and unmute as I heard

Date: Fri, 09 Apr 1999 10:48:12 GMT
I've been trying to get my 7200e at work running with linux and I did find
a nice web page with a step by step instructions. It seems everything
works until I load the pg driver. The only problem is that my dev
directory didn't have a pg0 file.
When the pg module was loaded it said something about having a major number
of 97, so I created a file in the dev directory called pg0 with a major
number of 97 and a minor number of 0. That didn't work unfortunately.
I did get the source code for cdrecord 1.61 but the documentation on how to
compile it to use the pg module is pretty slim. I don't know if it now
supports it like it didn't in earlier versions or not. When I try to
get it to use the recompiled cdrecord, it says something about
operation not supported by device.
Anyone have any luck with getting the HP 7200e working under linux?
Oh I did get it to load up as a pcd and I was able to read CDs off of the
drive.
I'm using mnandrake 5.3 as my base, with kernel 2.0.36.

If you don't need any unsolicited incoming connection to your box when
you are on line, edit /etc/hosts.deny to read:
ALL:ALL
If you get mail via SMTP from your ISP, you will probably need to
add an appropriate entry to /etc/hosts.allow. Something like:
smtp:your.isp.mail.net/your.isp.mail.subnetmask
You will also need to enable any other services that you need
in there too.
You need to then grant local host full access to everything, with
lines like:
ALL:127.0.0.1
ALL:your-ip-address
If you have your own local network (say, 192.168.0.*)
ALL:192.168.0.0/255.255.255.0
(If you leave that line out for now, you can test things from
elsewhere)
Next, edit /etc/inetd.conf.
Comment out any services that you don't want to run.
You don't need echo, discard, daytime, chargen, and can probably do
without time, nntp, finger, netstat, sysstat, netbios-ssn, netbios-ns,
swat, gds_db, and most of the others.
There may be some in that list that you do need
All those services that you do want to run, even if you only need them
for your own internal network, should be run using tcpd, which filters
connections based on /etc/hosts.{allow|deny}
For instance...
ftp stream tcp nowait root /usr/sbin/tcpd wu.ftpd
telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd
Leave identd as is.
Clobber inetd with a SIGHUP (killall -1 inetd) to make it re-read it's
files.
Now edit /etc/syslog.conf
Add a line
*.=warn;*.=info;*.=notice /dev/console
(You have to use TAB, not space in that file, I don't know why either)
This will cause most interesting messages to be logged to the console,
which (if you are running Xconsole) on your display, will mean that
while you are on line, you'll see various messages scrolling up as
various things happen. There are some xconsole implementations
that write to the root window.
Install the shadow password suite if you haven't already.
Check all accounts in /etc/passwd are either login-disabled, or
have new passwords. Remove/disable any accounts you don't recognise.
Standard accounts are:
root:x:0:0:root:/:/bin/bash
bin:x:1:1:bin:/bin:
daemon:x:2:2:daemon:/sbin:
adm:x:3:4:adm:/var/adm:
lp:x:4:7:lp:/var/spool/lpd:
sync:x:5:0:sync:/sbin:/bin/sync
mail:x:8:12:mail:/var/spool/mail:
news:x:9:13:news:/var/lib/news:
uucp:x:10:14:uucp:/var/spool/uucppublic:
operator:x:11:0:operator:/root:/bin/bash
man:x:13:15:man:/usr/man:
postmaster:x:14:12:postmaster:/var/spool/mail:/bin/bash
nobody:x:65535:100:nobody:/tmp:
You probably don't need 'operator'. You can effectively disable
an account by removing the last field (the shell), so that if
someone gets in on that account, they get straight out again.
Change the root password. Remove extra accounts with uid 0.
Scan your system for new suid-root executables
find / -perm +6000 -type f -exec ls -ld {} \;
This will generate a list of binaries with the suid/sgid bit
set. If any have been added that you don't recognise as something
that needs to be suid, reinstall it.
All of that won't necessarily make you 100% secure, but it should
put a few road blocks in the way.
As per usual, these instructions come with no warranty. If you break
something, you get to keep both pieces.
Regards,
Jim
