Even more fun on HP-UX is that in addition to the hosts line in nsswitch.conf they allow for a separate line called ipnodes used by IPv6 routines whereas hosts is only used by the older routines (gethostbyname etc...). It bit me when using NetBackup 7 because Symantec started using the IPv6 routines there where they hadn't in 6.5. HP's nslookup kept returning the correct entry from /etc/hosts but NBU refused to see it because I didn't have the ipnodes line.

But its use as a troubleshooting tool is limited at best (misleading and confusing at worst) in that environment for testing how application resolution will work. And this is because it uses its own logic and not the high level resolver APIs that applications call. (And even if it did use the high level resolver APIs - it wouldn't necessarily be using them with the same options that an application does anyway - particularly around IPv6 versus IPv4). _______________________________________________ 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 Athena(r), Created for the Cause(tm) Making a Difference in the Fight Against Breast Cancer --------------------------------- CONFIDENTIALITY NOTICE: This e-mail may contain privileged or confidential information and is for the sole use of the intended recipient(s).
