| help | |
| Saying Y here will include support for the DNS Resolver key type | |
| which can be used to make upcalls to perform DNS lookups in | |
| userspace. | |
| DNS Resolver is used to query DNS server for information. Examples | |
| being resolving a UNC hostname element to an IP address for CIFS or | |
| performing a DNS query for AFSDB records so that AFS can locate a | |
| cell's volume location database servers. | |
| DNS Resolver is used by the CIFS and AFS modules, and would support | |
| SMB2 later. DNS Resolver is supported by the userspace upcall | |
| helper "/sbin/dns.resolver" via /etc/request-key.conf. | |
| See <file:Documentation/networking/dns_resolver.txt> for further | |
| information. | |
| To compile this as a module, choose M here: the module will be called | |
| dnsresolver. | |
| If unsure, say N. |
