DHCPD problem
Hi All
I have dificulty using DHCPD on Linux server (rh7.3) with 2 interfaces
I found out the dhcpd require me to specify all the interfaces on the
server to start even if i dont want to use ( in this example eth0 ) one
of the interfaces.
the HOWTO recomended me to enter this line for the unused eth0
subnet 194.90.15.160 netmask 255.255.255.224 {
}
but then when I start to get DHCP Discover both interfaces send DHCP
Offer and the client which return DHCP Request to confirm get DHCP
NAK from the eth1 while eth0 send DHCP ACK.
This result in endless retries.
if I do ifconfig eth0 down all work and the client get its ip ( after
i comment the eth0 enteries in the dhcpd.conf file )
if I leave both interfaces up and fill the missing option in the
194.90.15.160 subnet the client succesfuly lease an ip from this subnet
here is the dhcpd.conf 4 yours inspection:
default-lease-time 600;
max-lease-time 7200;
option domain-name-servers 192.168.0.1;

The Diagnosis section of pptp,
http://pptpclient.sourceforge.net/howto-diagnosis.phtml#read_io_error
says there are likely errors in config files. Various mailing list
archives on the net suggest checking the secrets files when LCP
timeout sending Config-Requests occurs. Tsahi wrote this in
http://plasma-gate.weizmann.ac.il/Linux/maillists/01/08/msg00528.html
If you get LCP: timeout sending Config-Requests, your redback at bezeq
probably is experiencing difficulties or it is rebooting because of an
overload. the problem could also be you have some configuration problem, but
if your connection was up and now it is down, it is highly unlikely. you
should call 1800-340-340 and ask whats up, or wait a few minutes until the
redback reboots (if it is the case).
I have waited much longer than a few minutes, I just got ADSL
installed - it has never been up, and Bezeq support are not very
helpful. I'd like to verify that I am doing everything right before I
call them again.
I set up {chap,pap}-secrets according to the HOWTO (I think)
[root@trillian ppp]# cat /etc/ppp/chap-secrets

RE: DHCPD problem
I encountered the same problem.
what you have to do is edit /etc/sysconfig/dhcp
and set the DHCPDARGS to the interface or interfaces you want dhcpd to
listen on.
root@gw etc# cat /etc/sysconfig/dhcpd
# Command line options here
DHCPDARGS=eth1
that way dhcpd will listen only on one interface, and you won't have to set
up a dummy range on your other interface.

Re: ADSL: LCP: timeout sending Config-Requests
I don't know how helpful this is, cuz I run FreeLSD, but essentially pptp
and ppp are rather the same.
I have /etc/ppp/ppp.conf that looks like:
Actcom:
set authname aris@IActcom
set authkey putpasswordhere
set timeout 0
set ifaddr 0 0
add default HISADDR
enable dns
set mtu 1452
[If ppp scriptos on linux have slightly different syntax -- use yours
here]
and I hit it by doing a simple:
/usr/local/sbin/pptp 10.0.0.138 Actcom
Note: the whole RELAY_PPP1 thing is not mandatory, at least on the ALCATEL
modems. notice I don't use it.

Oleg Goldshmidt wrote: Actually, come to think about it, contrary to what I wrote in the posting that puzzled you, one can argue that a device driver is a piece of software that makes a particular piece of software work, using knowledge of its specific characteristics that are outside of Linux scope. Thus a linux device driver is related to Linux only insofar as it enables the hardware to work with Linux, but the hardware spec it is based on is not Linux-specific, and thus the device driver is not a derivative product of the Linux kernel in this sense, so proprietary drivers are OK. A device driver is basicaly the same for a given device under a given architechure. In each system, the driver gets parameters, takes control of interrupts (if necessary), gets requests and reports status differently. The basic manipulation of the device is the same, e.g. load firmware, set interupts, buffers, etc, start i/o, get the repsonse, etc. While the code may be different (or not) the driver for device X on archiechture Y looks the same no matter what language it is written in. Probably not enough to be restricted by copyright, but enough that anyone who is familiar with writting drivers could spot. Most linux drivers were written the other way arround however. Someone wrote a driver for a device, say a network card, and someone else pulled out the device specific code and stuck in new code for their device. This worked out well in the days when no-one had any idea of how to write a device driver and very few people had a specific device. You could hack together a driver without a lot of prior programing skill and it would work. If there was enough demand, it would get fixed and ocasionaly improved. In the 2.5.x kernels, there is a new method of accessing device drivers. Some drivers have been rewritten, some fixed, some left (now to be broken). Geoff. -- Geoffrey S.

Bezeq just told me (after a lot of we have no support for Linux and attempts to give me a 192.168.*.* address to ping while I had no connection) it was something on their side and they were working on it. To be fair to Bezeq's support, the last guy was friendly and did try hard to help, and didn't just slam the phone down after getting the unexpected reply to his question about OS I was using (he was just explaining to me that he was not knowledgeable in what was going on on my end, and was not sure thay had anyone knowledgeable around, though I did get an impression that there are some people with Linux expertise there, though not necessarily always).

RE: DHCPD problem
I don't think so
In the man page u can see : COMMAND LINE
The names of the network interfaces on which dhcpd should listen
for broadcasts may be specified on the command line.
In the dhcpd init script u can the line: daemon /usr/sbin/dhcpd
${DHCPDARGS}
Thet start the daemon on a specific interface.
It is not part of the configuration, it is part of the daemon startup
process

Subject: DHCPD problem
Hi All
I have dificulty using DHCPD on Linux server (rh7.3) with 2 interfaces
I found out the dhcpd require me to specify all the interfaces on the
server to start even if i dont want to use ( in this example eth0 )
one
of the interfaces.
the HOWTO recomended me to enter this line for the unused eth0
subnet 194.90.15.160 netmask 255.255.255.224 {
}
but then when I start to get DHCP Discover both interfaces send
DHCP
Offer and the client which return DHCP Request to confirm get DHCP
NAK from the eth1 while eth0 send DHCP ACK.
This result in endless retries.
if I do ifconfig eth0 down all work and the client get its ip (
after
i comment the eth0 enteries in the dhcpd.conf file )
if I leave both interfaces up and fill the missing option in the
194.90.15.160 subnet the client succesfuly lease an ip from this
subnet
here is the dhcpd.conf 4 yours inspection:
default-lease-time 600;
max-lease-time 7200;
option domain-name-servers 192.168.0.1;
subnet 192.168.0.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.0.255;
option routers 192.168.0.1;
range 192.168.0.2 192.168.0.5;
option domain-name internal.co.il;
}
subnet 194.90.15.160 netmask 255.255.255.224 {
}

Re: ADSL: LCP: timeout sending Config-Requests
actually what hacking your modem refers to, is making it initiate the ppp link by itself and therefore, cancelling the need to set up pptp in the computer itself, which in addition to activating the dhcpd in the modem can make life pretty easy for you. (something that could solve the problem in the discussed case, although it is illegal) Try entering your modem with a browser on port 80 and looking at the pptp tab. (default password is blank - what is commonly referred to as hacking your modem by 3LiT3 H4x0Rz..) -- Barak Kaufman (3LiT3 H4x0R) :P Customer Support Manager Oz-Tech Information Systems To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

In the man page u can see : COMMAND LINE
The names of the network interfaces on which dhcpd should listen
for broadcasts may be specified on the command line.
In the dhcpd init script u can the line: daemon /usr/sbin/dhcpd
${DHCPDARGS}
Thet start the daemon on a specific interface.
It is not part of the configuration, it is part of the daemon startup
process
But on redhat you normally start dhcpd with the init script, not directly
with /usr/sbin/dhcpd .
Should have RedHat patched their local man page? (to add a reference to
the sysconfig documentation?)
Anybody care to file a bug report to them?

Simulating a high latency link on a LAN using netfilter
Hey all. Anyone knows of a netfilter module that can be used (or any other way) to deliberately stall a packet in the router ? I want to create a situation in which machine A communicates with machine C on a LAN, through machine B, the linux router, and to stall the packets for a pre-determined amount of time. I've thought of course of overloading the router to the point where it lags naturally, but that's a bit of a crude solution.

To have done it right, /etc/rc.d/init.d/dhcpd should have sourced
/etc/sysconfig/dhcpd, where the line DHCPDARGS=whatever would be
put if wanted and then used the line:
daemon /usr/sbin/dhcpd $DHCPDARGS

RE: DHCPD problem
That's exactly what /etc/init.d/dhcpd does.
it sources /etc/sysconfig/dhcpd and uses daemon /usr/sbin/dhcpd
${DHCPDARGS}

Nevertheless, if I won't find any pre-made tool to achieve this, I think I'll try and do it. I think it can be a very handy tool in testing enviroments.

RE: ADSL: LCP: timeout sending Config-Requests
Note: the whole RELAY_PPP1 thing is not mandatory, at least on the ALCATEL modems. notice I don't use it. Interesting. Can anyone confirm or deny it? Should it be in the HOWTO? A month or two ago my (Alcatel) ADSL stopped functioning altogether. Might have even been the same timeout sending Config-Requests error, but I'm not sure. The nice Bezeq tech-support person suggested that I change remotename to 10.0.0.138 (and the matching field in pap-options, etc), which fixed the problem. He wasn't as helpful in telling me why this change was suddenly required, but there you go. = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
