G'day Phil,
You need to make these users "guest" class users. Here's how:
The crux of the matter is the class of ftp user. In wu-ftp, there are three
classes of user:
- Real User
- Guest User
- Anonymous User
When the real user (default) logs in, they do not get chrooted( ).
When a guest user logs in, they get chrooted( ) to their home directory as
defined in the /etc/passwd file
When an anonymous user attaches, they get chrooted( ) to the ftp daemon's
home directory.
To get an ordinary user to be a guest, you need to put them into a
/etc/group as, say, 'ftpusers'. Like so:
ftpusers::101:nigel,gmcs,ann
They have an entry in /etc/passwd like:
ann:xxxxxxxxxxxxx:511:101::/home/ann:/bin/ftponly
(xxxxx...) is replaced by their encrypted passord if not using shadow
passwords. Note the group they belong to.
Then, in /etc/ftpaccess, put stuff like:
class all real,guest,anonymous *
# root is aliased to an admin mailbox by the mail program
email root@localhost
loginfails 5
# The only thing a guest user can't do is chmod
compress yes all
tar yes all
chmod no guest,anonymous
delete no anonymous
overwrite no anonymous
rename no anonymous
# Log all transfers
log transfers anonymous,guest,real inbound,outbound
# This line determines what group is the guest group
guestgroup ftpusers
# You can specify global filespecs to leave alone
noretrieve .qmail .*
# You can also restrict upload to only the home/username/public_html
directory
upload /home/* / no
upload /home/* /bin no
upload /home/* /bin/* no
upload /home/* /etc no
upload /home/* /etc/* no
upload /home/* /lib no
upload /home/* /lib/* no
upload /home/* /public_html yes
Restart inetd and it should work with the 'home' directory as the users root
directory.

AFIAK you can't. The developers of pppd seem to resist requests for

Yes. This is the default behaviour on recent kernels. (Can't recall

Use pppd.

Date: Sun, 17 Jan 1999 00:01:40 GMT
I am trying to get my AVM Fritz! PCI passive ISDN card to work on
Linux - Red Hat 5.2. (This card is also sold in the UK as a BT
Speedway card.)
What I need is a simple step-by-step setup guide, written in English,
for someone who is computer and Unix knowledgable, but a Linux
newcomer.
I've searched the web and usenet archives, but most of what I find is
in German. While I can have a natter over a beer in German, I am
completely defeated at this technological level.
Any help would be most welcome. (BTW, my ISP's news feed is NBG so a
copy of any responce by e-mail would be welcome :-)
Regards,
Alistair.
PS This message was sent from WinNT only 'cos I can't get my ISDN card

I have information for the header file that needs to be changed. But......
How do I recompile the binaries for ipfwadm (command line)?
For now I downloaded the RPM ipfwadm-2_3_0-5_alpha.rpm and installed it.
This older rpm works but I would like to use the new one and recompile it.

If all you have are two stations, I beleive that the likelyhood that you
would have collisions
should be the same with or without a hub when in half duplex. If you
can configure each end of
a two device ethernet connection to be full duplex, collisions by
definition do not happen.
In general, unless you have a lot of traffic initiated on both ends, you
won't see a lot of
collisions on a half duplex point to point connection. Also, contrary
to popular opinion,
collisions are not in themselves a bad thing. Collisions and how they
are handled is the
mechanism that makes ethernet work at all.

Actually, although 10/100 AutoNegotiation is supposed to be backwords
compatable with
10BASE-T, in practice there can be problems, especially with older
10BASE-T devices.
In any event, I would recommend using a crossover cable using CAT-5
cable (the required
class of cable for 100BASE-TX). You may need to fix the 10/100 port at
10 Mbps and disable
AutoNegotiation. Electrically, there is no problem.

Yeah, I set the subnet mask with the ifconfig command. I tried to set a
static route <with the correct netmask and gateway values> using the route
command, but I got a 'Network Unreachable' error. I've been told that this
normally indicates my netmask is screwy, but I've triple checked it and the
one I set is correct. I've tried pinging my host on the network and I get the

Subject: PPP configuration problem
I'm running Redhad 5.2 and am trying to set up PPP. I have it working
perfectly as root, however it doesn't work right as any other user. I
can activate the connection as root (either by logging in as root and
activating it, or by using su from a user account ) and as long as I am
root, it works great, but when I try to use any network software from a
user account, it will no longer resolve the URL's. I can type the IP
numbers in and it goes to the address, but when I type the name, I get
a DNS error. The interface was created and is being activated using
netcfg.

You got to take the information with a grain of salt. I new the ppp was
outdated. But the fact that they actually had instructions for
connecting under linux was enough to get me to switch.

I know BellAtlantic.net uses PAP I had them as my ISP for a year. But I
could never connect with there service with any new version of PPP other
than 2.2.0 and it was outdated and I eventually want to move to kernel
2.2 and you need at least version 2.3.5 of PPP with it.

Yeah BellAtlantic doesn't support 56K. There service is good hardly no
busy signals in fact I can't remember the last time I had one. To bad
for you that BeOS doesn't support CHAP. I am sure glad Linux does.

It doesn't find the tcl-lib while linking. Either it's missing in the
link comando (there must be someting like -ltcl8.0) or it's lying
around in another directory where the linker couldn't find it, or
it's there but named sligthly differnet from the linker command
(e.g. -ltcl as opposed to -ltcl8.0).

It appears that the server emulates a Windows printer and a Netware
printer. Since it
doesn't do TCP/IP and Samba doesn't do IPX we can rule that out. However
Linux can run
Netware server software. The MARS_NWE package allows LinuX to emulate a
Netware 3.x
server, including print queues. The print box can then be attached to
the 'Netware' print
queue. Linux can the use nprint (part of ncp utils) to print to the
Netware queue.
Another possible solution may be to define a print share on your W95 box
that prints to
pn6125. The linux box can then use smbprint to print to the W95 box,
which then spools to
the server.
I'm sorry that the ideas above seem a bit clunky, but the correct
solution would involve
getting a better print server that supports lpr/lpd over IP as well as
Windows printing. I
guess the obvious solution of chucking the print server and using the
Linux box to drive the
printer directly, and using Samba to provide Windows print services was
rejected for some
reason?
