kmtune vs lsattr
Thanks for your info. I have used lsattr -E -l sys0 command to look at the tunable kernel parameters. I cannot find any mention of minperm/maxperm nor minfree/maxfree in the output. Can these parameters only be accessed via kmtune? The box has live applications on it, so if invoking kmtune will affect the server in anyway, it won't be used.
The full output of lsattr -E -l sys0 gives:
# lsattr -E -l sys0
keylock normal State of system keylock at boot time False
maxbuf 20 Maximum number of pages in block I/O BUFFER CACHE True
maxmbuf 0 Maximum Kbytes of real memory allowed for MBUFS True

Are there any parameters here that need their values changing?
Thanks,

gss_inquire_context
gss_inquire_context(3) Library Functions Manual gss_inquire_context(3)
NAME
gss_inquire_context() - obtain information about a security context
SYNOPSIS
DESCRIPTION
The routine provides information about the security context to the calling application. The calling application must first have called the
routine for a handle for the credential.
Input Parameters
context_handle A handle that refers to the security context.
Output Parameters
src_name The name of the context initiator. If the context was established using anonymous authentication, and if the appli-
cation invoking is the context acceptor, an anonymous name will be returned. Specify NULL if not required.
context_handle The name of the context acceptor. If the context acceptor did not authenticate itself, and if the initiator did not
specify a target name in its call to the value will be returned. Specify NULL if not required.
lifetime_rec Returns the number of seconds for which the credential will remain valid. If the credential expired, the parameter
returns a 0 (zero). If there is no credential expiration, the parameter returns the value If an expiration time is
not required, specify NULL.
targ_name The name of the context acceptor. Storage associated with this name must be freed by the application after use with
a call to
mech_type The security mechanism providing the context. Specify NULL if not required
ctx_flags Specifies independent flags, each of which requests that the context support a service option. The following sym-
bolic names are provided to correspond to each flag. The symbolic names should be logically ORed to form a bit-mask
value.
The True/False values are:
True Credentials were delegated to the context acceptor.
False No credentials were delegated.
The True/False values are:
True The context acceptor has been asked to authenticate itself.
False The context initiator has not been asked to authenticates itself.
The True/False values are:
True Replayed signed or sealed messages will be detected.
False Replayed messages will not be detected.
The True/False values are:
True Out-of-sequence signed or sealed messages will be detected.
False Out-of-sequence signed or sealed messages will not be detected.
The True/False values are:
True Request that confidentiality service be made available
False No per-message confidentiality service is required.
The True/False values are:
True Request that integrity service be be made available
False No per-message integrity service is required.
The True/False values are:
True Do not reveal the initiator's identity to the acceptor.
False Authenticate normally.
cred_usage Returns one of the following values describing how the application can use the credential:
If no usage information is required, specify NULL.
mechs returns a set of security mechanisms supported by the credential. Specify NULL if not required.
minor_status Returns a status code from the security mechanism.
STATUS CODES
The following status codes can be returned:
The routine was completed successfully.
The referenced context could not be accessed.
The credentials were invalid.
The routine failed. Check the
minor_status parameter for details.
The routine could not access the credentials.
