I was trying to setup a file share between AIX and widnows servers. I have installed cifs filesets on my AIX LPAR. but when i was trying to mount the share on AIX , got the below errors.
I tried with all combinations by cleaning the file "cifscred". But still got the error.
Can any one of you used CIFS on AIX for file sharing purpose? If i can achieve fileshare using CIFS, then i may not go for samba server.
Please provide your ideas.
Thanks

Dear All,
I mounted a windows share on AIX 5.3. with cifs.
The write on it is much slower than from other windows clients.
Could you help me with any tricks to speed the writing process?
Thanks,

Hi all,
We are experiencing below mentioned error on mounting windows Share on AIX 5.3 when we migrate our TL from 8 to TL12-SP01, we also checked the allowed password length for mounting CIFS which is fine(10 characters in our case). On IBM fix central site there is a fix IZ63140 for... (10 Replies)

cifs.upcall
CIFS.UPCALL(8) System Administration tools CIFS.UPCALL(8)NAME
cifs.upcall - Userspace upcall helper for Common Internet File System (CIFS)
SYNOPSIS
cifs.upcall [--trust-dns|-t] [--version|-v] [--legacy-uid|-l] [--krb5conf=/path/to/krb5.conf|-k /path/to/krb5.conf]
[--keytab=/path/to/keytab|-K /path/to/keytab] {keyid}
DESCRIPTION
This tool is part of the cifs-utils 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.
OPTIONS -c
This option is deprecated and is currently ignored.
--krb5conf=/path/to/krb5.conf|-k /path/to/krb5.conf
This option allows administrators to set an alternate location for the krb5.conf file that cifs.upcall will use.
--keytab=/path/to/keytab|-K /path/to/keytab
This option allows administrators to specify a keytab file to be used. When a user has no credential cache already established,
cifs.upcall will attempt to use this keytab to acquire them. The default is the system-wide keytab /etc/krb5.keytab.
--trust-dns|-t
With krb5 upcalls, the name used as the host portion of the service principal defaults to the hostname portion of the UNC. This option
allows the upcall program to reverse resolve the network address of the server in order to get the hostname.
This is less secure than not trusting DNS. When using this option, it's possible that an attacker could get control of DNS and trick
the client into mounting a different server altogether. It's preferable to instead add server principals to the KDC for every possible
hostname, but this option exists for cases where that isn't possible. The default is to not trust reverse hostname lookups in this
fashion.
--legacy-uid|-l
Traditionally, the kernel has sent only a single uid= parameter to the upcall for the SPNEGO upcall that's used to determine what
user's credential cache to use. This parameter is affected by the uid= mount option, which also governs the ownership of files on the
mount.
Newer kernels send a creduid= option as well, which contains what uid it thinks actually owns the credentials that it's looking for. At
mount time, this is generally set to the real uid of the user doing the mount. For multisession mounts, it's set to the fsuid of the
mount user. Set this option if you want cifs.upcall to use the older uid= parameter instead of the creduid= parameter.
--version|-v
Print version number and exit.
CONFIGURATION FOR KEYCTL
cifs.upcall is designed to be called from the kernel via the request-key callout program. This requires 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. Support for this key type may eventually be deprecated (see below).
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 D C PROGRAM ARG1 ARG2...
#========= ============= = = ================================
create cifs.spnego * * /usr/sbin/cifs.upcall %k
create dns_resolver * * /usr/sbin/cifs.upcall %k
See request-key.conf(5) for more info on each field.
The keyutils package has also started including a dns_resolver handling program as well that is preferred over the one in cifs.upcall. If
you are using a keyutils version equal to or greater than 1.5, you should use key.dns_resolver to handle the dns_resolver keytype instead
of cifs.upcall. See key.dns_resolver(8) for more info.
