Hi
I configured our machine as a pppd server at last. Now I want to learn
how can I apply time limit for users who logged on server by pppd. ( 10
minutes is OK).

Hi,
I haven't found any pppd version implementing the -demand, -persist, and
-idle options.
These are very usefull for automatic reconnection.
Does someone knows a pppd version enabling these options?
Else, how do you enable automatic reconnection without these?
Thanx.

Subject: can't see network
Date: Thu, 29 Jul 1999 11:27:50 -0700
Hello all,
I've inserted a linux box into an existing NT network (public subnet) as
a firewall, and, no matter what I try, can't see either the network or
the internet from the firewall. I have had this same linux box
successfully set up to masquerade my ppp internet access on a different
win95 private network, and have tested both nics so I know they work.
If someone can point me in a direction to debug this I would surely
appreciate it. I've been banging my head for three weeks now...
The subnet is 209.xxx.xxx.160/255.255.255.240 Broadcast=209.xxx.xxx.160
The network has cable modem internet access with address
209.xxx.xxx.174. Everything works great until I plug in the firewall.
The firewall has 2 - 3c515 cards which show activity when I ping, but no
response. I can ping the modem (174) and firewall interfaces (172 & 173)
but nothing else.
eth1 (external interface) is set as 209.xxx.xxx.173 with gateway 174.
eth0 (internal interface) is set as 209.xxx.xxx.172 (no gateway - adding
a gateway here just seems to screw up my routing table).
The network clients have addresses between 161 & 166, with gateway =
172.
I have flushed the ipchains rules - they are wide open.
I'm running Redhat 5.2, kernel 2.2.5-15.

Is it possible to set up a DNS name that has a primary and secondary IP
address? If so, can DNS detect that a primary is down and therefore
switch to the secondary?
TIA.

My hosts.deny and hosts.allow files are empty.
I can telnet into the exporting machine from the 'mount' machine with no

The machine that I am attempting 'mount' from does not have a DNS entry.
I tried adding its IP address into the exports file to see if that made
any difference but it still did not work.

You might want to check out the security "language" features of

able to execute a chroot command from one of those files.

Merhaba G�kalp,
I assume you mean "time limit for *idle* users.
For a timout based on line activity 'man pppd' says :
idle n Specifies that pppd should disconnect if the link is idle
for n seconds. The link is idle when no data packets
(i.e. IP packets) are being sent or received. Note: it is
not advisable to use this option with the persist option
without the demand option. If the active-filter option is
given, data packets which are rejected by the specified
activity filter also count as the link being idle.
You can put it on command line (overrides everything),
/etc/ppp/options.ttyS? (overrides all except command line options),
~/.ppprc file (overrides only options file), or /etc/ppp/options
(defaults) from highest priority to lowest priority.
So, by putting different time out values into different dial-in tty
groups (options.yyS?) you can define timeouts based on line activity.
For a timeout based on userid, you can put this option into user's
~/.ppprc file. But in this case you cannot use getty to invoke pppd
directly for a chatscript-less dial-in. Instead, you must define a user
account (you will do that anyway if you also plan giving telnet access
to users) and invoke pppd from within ~/.bashrc file. So user must enter
his/her userid and password in chatscript (or manually), which may not
be what you really want.
Other than that, I seem to remember a utility somewhere to force-logout
an idle user. Just search it in metelab, or http://www.linuxapps.com/
or http://linuxberg.ankara.edu.tr/
Kolay gelsin,

I recently installed Redhat 6.0, and for some reason I cannot telnet to the

Trying 152.7.8.26...
Connected to afc-008-026.rh.ncsu.edu.
Escape character is '^]'.
Connection closed by foreign host.
I get similar results when I telnet to localhost from the machine itself.
As best as I can remember, I have not changed any of the config files from their
default state with the exception of /etc/issue.net. The /etc/hosts.* files are
empty.
I can ftp to this machine using wu-ftpd with no problems at all, and I can
telnet out with no problems at all. Can anyone provide some clues about what
might be wrong?

The Linux server works fine. It is just the client who has problems. If
you put in a URL from the client when the server is not online, the
server connects to the ISP and then the client tells you it cannot
resolve the name.
I don't know if anything is correct anymore. Could I send you some
files and have you look at them?
