LinuxQuestions.org - [SOLVED] not able to permanently mount samba share on linux

my samba server is working properly but i want to mount it permanently on linux (red hat) client.i have tried /etc/fstab and also autofs service but both are not working for me.
1. /etc/fstab
i made the following entry in it
//192.168.0.254/myshare /temp smbfs credentials=/root/pass 0 0

and when i use comman mount -a it shows "unknown filesystem smbfs"
why this is so?

2. using autofs
my auto.master file is shown below

# Sample auto.master file
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# For details of the format look at autofs(5).
#
misc /etc/auto.misc
/net -hosts
#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.

"/etc/auto.master" 21L, 587C

cd -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom

# the following entries are samples to pique your imagination
#linux -ro,soft,intr ftp.example.org:/pub/linux

samba -fstype=smbfs,username=vinita,password=redhat ://192.168.0.254/myshare
