Re: [Dnsmasq-discuss] DHCP doesn't seem to respond to requests(?)

I have decided to start small - connecting with an UBUNTU laptop - but my dhclient eth0 requests consistently end with No DHCPOFFERS received.

Can't you turn off all firewalling on client and server? (unconnecting them from dangerous world first ;-) You can also test it adding tap interface (can be in a bridge with eth0) and then running something like: qemu -net nic,model=pcnet -net tap,ifname=tap0,script=no,downscript=no -boot n ...and watch tcpdump -i tap0 (br0) -- jasiu

Re: [Dnsmasq-discuss] Multiple Macs - Same IP

Beware that this is a dangerous thing to do, it will only work reliably if only one of the hardware addresses is active at any time and there is no way for dns- masq to enforce this. It is, for instance, useful to allocate a stable IP address to And I suggest using dhcp-hostsfile - less to write and more elegant way. -- Jan
Re: [Dnsmasq-discuss] Feature request for dhcp-hostfiles to behave like addn-hosts
A tangential question, I've increased MAXLEASES to #define MAXLEASES 16384 in config.h. Is there any danger in having this many leases and increasing this even higher if necessary? I'm a few weeks away from being able to test this at scale and appreciate any warnings or feedback anyone might have now. If you get bitten anywhere, it will be performance writing the lease file. That gets truncated and re-written for every change. On reasonable storage it should be fine, but maybe not on a slow flash drive. If it's a problem that's that prefect excuse to write a script to move the database to a MySQL backend, right? If you would talk about SQLite rather, Simon, it would look more achievable :-) Nearly every Linux (and not only) uses SQLite in some places nowadays, and any database which needs a server complicates things. I understand, that it is only a proposal for users, but with one-file-database it can be included as #ifdef SQLITE patch. -- Jan

Re: [Dnsmasq-discuss] dnsmasq-2.43rc3 caps failed
On Linux 2.6.24 (Gentoo kernel, though I don't see why it wouldn't
happen on other distros), starting this release with the user set
to anything other than root fails with this message:
dnsmasq: setting capabilities failed: Operation not permitted
I think I may have been guilty of answering the question I expected
in my last reply. Its valid if what you are talking about is running
(as root)
dnsmasq --user someuser
if you are actually starting dnsmasq as someuser (presumably
listening on a high port) then I can see that changing the capability
error from soft to hard is a problem. The solution is not to attempt
any of that stuff if the original process uid is non-zero.
I'll fix that before a final release.
?
I use kernel 2.6.25 on recent Gentoo, and have no such problem (and
never before had). I never cared of using capabilities (I don't know
much about it, but enough to remove capabilities setting from kernel
tun driver -- it does not let run qemu -net tun as normal user).
On Gentoo dnsmasq is started that way:
start-stop-daemon --start --exec /usr/sbin/dnsmasq \
--pidfile /var/run/dnsmasq.pid -- -x /var/run/dnsmasq.pid \
${DNSMASQ_OPTS} # =
so it runs as nobody, as he likes. Running:
dnsmasq --user nobody
as root goes without problems and as normal user I must use:
/usr/sbin/dnsmasq -u jasiu --dhcp-alternate-port 1067 -d -p 1053
and disable TFTP server because of port numbers.
All on 2.43rc3. Kernel compiled for my machine. Dnsmasq runs well.
