Re: [bind-users] Slow reply under heavy load (on a specific NIC ip)
Can you please provide some specifics about your setup that is experiencing the problem? HW - Sparc, PPC, Intel x86/x64, ARM ? OS - what OS is the problem occurring on? specific BIND version? anything about the NIC in question, possibly to include mfg && model number, if relevant?

Under particular heavy load mometns, with some hundreds of concurrent queries coming in, sometime Bing stops answering for some seconds or answer with important delays. But, when i try to query the same server/same Bind on a NIC alias IP during congestion on the main IP, everything is fast! I changed some tunings in: max-connections in /proc txqueue in network ipv4_ports and i mitigate something. But it is not completely solved. Do you think Bind could have some NIC IP limit? Some ideas? Really thank you!

Re: [bind-users] dhcp failover is not working as expecte
Julie,
Not intending to come across as rude, but is this the list you intended to post
to?
FWIW, you posted to the BIND list, not the DHCPD list.
Good luck,
Jerry

Hi,
I have dhcpd running on two servers. Share the load 50%.
I expect if one of the servers has issue, another one will automatically take
over for all 100% clients.
But, the fact is not. When one of them down, or frozen, half of users had lose
network without ip address.
My configuration is:
failover peer "primary_secondary" {
primary;
address 111.111.111.111;
peer address 222.222.222.222;
port 8068;
peer port 8068;
max-response-delay 60;
max-unacked-updates 10;
mclt 300;
split 128;
load balance max seconds 3;
auto-partner-down 0;
max-lease-misbalance 15;
max-lease-ownership 10;
min-balance 60;
max-balance 3600;
}
Could I get some explanation on why it is happed? And how to avoid it?
Any comments will be appreciated
Thanks in advance
Julie

Re: Defense against a client?
I suspect that the NAT/PAT thing is at its peak (across the Internet) right now. I expect to see it beginning to dissipate in the coming years with the adoption of IPv6.

Re: Operating system recommendation
I have ran BIND on Sun/Oracle Solaris since 1994 beginning with Solaris 2.3. When I started, that was back in the BIND 4.X days. Solaris has always provided a positive experience for me as a BIND server.

compiling BIND on AIX
I have compiled BIND many times on Solaris/OpenSolaris and several different *BSD's, and this has always been a pretty simple procedure. I currently need to compile (a current) BIND on AIX 5.2 and it appears to me that there is a little more work involved to get a successful compile on this platform vs. others that I have worked with. Can anyone who is currently compiling/running BIND on AIX share any getting started pointers ( i.e. BIND only compiles with gcc, etc)?? A search of the archives indicate that there are people on the list running BIND on AIX, but I was unable to uncover any specific tips, hints, etc. as to getting a good compile.
