Hi With the announcement that: “Advisory — D-root is changing its IPv4 address on the 3rd of January.” https://lists.dns-oarc.net/pipermail/dns-operations/2012-December/009428.html We are running 9.7.3-P3 on the Auths, and 9.8.1-P1 on the resolvers. We currently do not use a root hints file – If we put a hints file in named.conf, then will named will use it, rather than the compiled in hints? Bruce Hayward There are 340,282,366,920,938,463,463,374,607,431,768,211,456 IPV6 IPs divided by 7,000,000,000 (seven billion) people on the earth in 2011 = 4.86117667 × 10 to the 28th IPV6 IPs per person. That should be enough for about 48 octillion, That is 48 followed by 27 zeros) 48,000,000,000,000,000,000,000,000,000 IPV6 devices per person. - approximately... ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
Settings for File Descriptors
Hi I am trying to understand file descriptors with bind in mind, and what they should be set at in conjunction with the OS. We are running 9.5.1 P1 on Solaris 10 (patched up), which is basically all that is on each server. Some questions: 1) Is there a recommended setting (number of FDs)? 2) Better to set this at the kernal level with the set rlimit, or a compile option with configure, or both 3) Should the number be correlated to the number of recursive clients? 4) Different on the auth servers? Thanks Bruce Hayward ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

BIND will set the file descriptor resource limit to unlimited when it starts up, unless you tell it not to in the options setting. Just forget about it. 2) Better to set this at the kernal level with the set rlimit, or a compile option with configure, or both This doesn't apply to BIND (see above) but I think it foolish to mess around with /etc/system to change resource limits for all processes, when you can easily use a targetted ulimit command in the calling script for the process that actually needs it. BIND doesn't have a compile option for this, anyway, AFAIK. Are you confusing this with the FD_SETSIZE value? BIND 9.5.1-P1 on Solaris will not be using select(3c) anyway, so that isn't an issue. 3) Should the number be correlated to the number of recursive clients? 4) Different on the auth servers? If you did go out of your way to make it other than unlimited, then yes to both. But don't. -- Chris Thompson Email: c...@cam.ac.uk ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
