cifs.upcall - Userspace upcall helper for Common Internet File System (CIFS)
|
cifs.upcall [−c] [−v] {keyid} |
This tool is part of the samba(7) suite.
cifs.upcall is a userspace helper program for the linux CIFS client filesystem. There are a number of activities that the kernel cannot easily do itself. This program is a callout program that does these things for the kernel and then returns the result.
cifs.upcall is generally intended to be run when the kernel calls request−key(8) for a particular key type. While it can be run directly from the command−line, it´s not generally intended to be run that way.
−c
When handling a kerberos upcall, use a service principal that starts with "cifs/". The default is to use the "host/" service principal.
−v
Print version number and exit.
cifs.upcall is designed to be called from the kernel via the request−key callout program. This requres that request−key be told where and how to call this program. The current cifs.upcall program handles two different key types:
cifs.spnego
This keytype is for retrieving kerberos session keys
dns_resolver
This key type is for resolving hostnames into IP addresses
To make this program useful for CIFS, you´ll need to set up entries for them in request−key.conf(5). Here´s an example of an entry for each key type:
#OPERATION TYPE
