Personally I use Ctrl-X-C and Ctrl-X-O in Midnight Commander for
housekeeping permissions. It's quick and easy.
On my system, I've made myself a member of group pppusers, and set the
permissions as follows:
ppp-on/off xxxx-x--- root pppusers

dialler xxxx-x--- root pppusers

Is it just slow getting the login? If so then add entries for your other
machines in /etc/hosts. Your probably getting reverse DNS lookup timeouts.

One nit: the digital side of the connection MAY be done using an ISDN
device, including a BRI line, which is something that ordinary mortal
users can sometimes buy. (Not always, of course. I can't get ISDN
where I live ...)
Terminating V.90 with ISDN works as long as there's only one D to A
conversion in the path back to the analog modem user.

Thanks for both your advices.
The "mod_userdir" is loaded.
Using 705 access rights solves my problem. That way authorized users cannot
access the homedir, but Apache can show the "public_html" dir. 701 could
perhaps work too.
Now the problem is making a "post user creation schript". It should set 705
access to the userdir after creation of a new user for automation.
I try, by copying the accountarchive.sh file userconf uses, and changing
this to
include a line like "chmod 705 $BASE/&USERID"
It doesent help. Can you help me out on this one also?

Actually, what I was trying to say is not that a 100% collision rate is ok, but
that, even with 100% collisions, performance doesn't take too big a hit.
Consider 10Mb/s ethernet (I don't have even crude numbers on 100 Mb/s usage).
An ethernet packet is just over 1500 bytes long. If every packet transmitted
results in a collision, then all packets are lengthened by 40 bytes (collisions
only occur at the beginning of transmission and are guaranteed to be detected
within that 40 byte window). This decreases your maximum throughput from 10
Mb/sec to 1500/1540 * 10 Mb/s, or 9.74 Mb/s. Obviously, this is horribly
simplified, but I think it does help put collisions into perspective. On my
test network (dirt cheap 10 Mb/s hub and 2 linux boxes), I run an X server on
one machine and X applications on the other. Even with 25% collisions, I can
maintain an ftp transfer rate of 1100 KBytes/sec between the two boxes without
noticing any sluggishness. I haven't tried at 100 Mb/s --- I suspect that the
higher speed would decrease the number of collisions, while the larger
collision detection window would increase the penalty for those collisions.

Hi!
Well I parsed thru the FAQs but didnt found it :-(, i have the following
situation.
Intranet with an IP of 10.114.0.0 and a Internet address of e.g 200.100.99.0
I want to do the following:
I have a bunch of Machines which should be able 2 went to the Internet with
dynamic masq., thats not the problem.
BUT
I want one machine with an private 10.114.69.69 to have an STATIC masqed
200.100.99.33 address. so that I can telnet form the Internet to 200.100.99.33
and my linux-router with ipfwadm directs me to 10.114.69.69.
well i could use ipautofw for the port but I want to use every port on that
machine. I hope some1 has an Idea following a small drawing for what I mean.
Machine A
IP: 10.114.69.69
Linuxrouter 200.100.99.33 Shoud route 2 MachA
w/ ipfwadm 200.100.99.99 Dynamic for the rest
IP: 10.114.something

I've had a PPP connection (set up using kppp) working perfectly from
Mandrake 5.3 with a 2.2.5 kernel for months.
Now suddenly I can't access web sites, with either Navigator, lynx or
the KDE web browser. Navigator gives the most sensible error message,
and says:
"A network error occurred:
unable to connect to server (TCP Error: No route to host)
The server may be down or unreachable."
The funny thing is that ping, FTP, POP3, SMTP, NNTP and so on work fine.
What on earth have I done?
Thanks for any help.

I wasn't suggesting bombing as such (repeated large e-mails), but a single
one from me, a single one from you... makes one big whale on their account,
and doesn't block the line I'm on too much.
Students in Norway protested against... uh, what was it again? Can't
remember... Anyway, we didn't "bomb" the government representatives, but
someone make a script that would send a generic letter, with the name you
wrote, to a dousin representatives. Small thing, but a lot of students did
it...
I do not call this bombing, but the communications company just dropped the
whole bunch of e-mails. Sort of the postal service burning postcards if the
sack gets too heavy. *grrr*
