mount -t nfs server:/path /mnt/point #linux
mount -F nfs server:/path /mnt/point #solaris
mount -o remount,suid /mnt/point # "remount" a fs, so as to set new mount options
# should be able to remount ro fs as rw
/etc/dfs/dfstab Solaris, eg:
share -F nfs -o ro -d "tin-sun /mnt/cdrom" /mnt/cdrom
share -F nfs -o ro -d "tin-sun vold /cdrom" /cdrom/cdrom0
#share -F nfs -o ro -d "tin-sun vold /cdrom" /cdrom/sol_10_305_sparc # don't work for OS cd
share -F nfs -o ro -d "tin-sun vold /cdrom s0" /cdrom/sol_10_305_sparc/s0 # need to export each slide separately
share -F nfs -o ro -d "tin-sun vold /cdrom s1" /cdrom/sol_10_305_sparc/s1 # as they are mounted separately.
mount -F servername:/exportName /mount/point
cdrom : hsfs /dev/rdsk/c0t6d0s0 /cdrom
dos : pcfs
If not using vold to manage cdrom, add entry like this to the vfstab:
/dev/dsk/c0t6d0s0 - /mnt/cdrom hsfs - no -
showmount -e : display the devices shared by a remote host that can be mounted
showmount -a : list remote system that has mounted a export
solaris loopback fs, sample entry in vfstab, as per man page on mount:
/export/test - /opt/test lofs - yes -
removable media management - vold
in sol up to 9, vold is very buggy, and tend to cause problem,
especially after hitting eject button on cdrom drive w/o using soft "eject cdrom"
if it goes bad, stop,start don't seems to help. need reboot.
in sol 10, seems to be better, at least volmgt stop,start clear things up.
sol 10 handles usb dev mounting pretty good.
mounting them correctly and showing icon on desktop.
Files can be access in /rmdisk/...
- usb floppy drive from apple
- usb cd/dvd/burner from iomega
- usb memory storage (lexar jumpdrive)
usb devices are hot plug detected by kernel since solaris (8?).
usb hard drive should work since solaris 8.
see gmail ref for more info.
/dev/usb/... is driver, and sym link created into /dev/[r]dsk/
though somehow format did not see the disk.
other vold paths:
/vol/... (/vol/dev/[r]dsk, /vol/dsk, ...)
some maybe used as raw path for floppy dd when vold is running.
mount -t vfat -o loop=/dev/loop0 /tmp/floppy.dd.img /mnt/loopbackmount
: use loopback to mount a dd-ed image of a dos floppy, fully writable.
mount -t iso9660 -o loop,ro /tmp/cdrom.dd.img /mnt/loopbackmount
: same as above, mounting imaged created from cdrom
# NFS export cannot see loopback devices (at least in linux, solaris)
# and loopback from a file based off NFS won't work either
# Typically, supports only 8 loopback "devices" unless edit loop.c and recompile kernel
dd if=/dev/cdrom of=/tmp/cdrom.dd.img : create dd image out of cdrom, using raw dev.
mount -t smbfs -o username=tin,password=foobar //n2k/c$ /mnt/n2k/c$ (trying in rh7.1 jaba)
mount -t smbfs -o 'username=administrator,password=bar,workgroup=ntdom2' //10.0.71.231/cifs /mnt/smbfs
fuser : which user holding up what file, useful when mounting, etc
fuser -cu : -cu show user and resolved user name using a particular mount point
mount -t ...
cdrom is iso9660
Making ext2 floppy
create primarty partition of type Linux (ext2)
mount -t ext2 /dev/fd0 /mnt/floppy
or mount /mnt/floppy (auto determine fs type should work).
linux sample /etc/fstab:
/dev/hda1 / ext2 defaults 1 1
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/hda6 /var ext2 defaults 1 2
/dev/hda7 /work ext2 defaults 1 2

none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hda5 swap swap defaults 0 0
# external mounts
//10.0.1.245/c$ /mnt/tin-nt/c$ smbfs noauto,username=tin 0 0
192.168.71.30:/ /mnt/test nfs noauto 1 1

/img/rhel-3-cd1.iso /mnt/rhel-3-cd1 iso9660 loop,ro # cd iso img from rhn ftp
# mount option user will default to noexec
# sometime loopback mount will complain with strange message if image is not on a local fs
linux sample /etc/exports:
# Either use
# (1) space delimit multiple machines of the same export dir
# each machine options must be given immediately, colon (or comma) CANNOT be used
# to group multiple machines with same option as in Solaris
# (2) each machine has its own line, with mount point repeated.
# Then run exportfs -a to export everything
# (eg 1)
/mnt/usbdrv tin-sun(rw,no_root_squash,async) chong-sun(rw,no_root_squash,async)
# (eg 2)
### smb.conf and related stuff
security = domain,
smbpasswd -j ntdom1 -r '10.0.72.15' -UAdministrator%password
USB hard drive on linux.
Hot plug ok.
Tested on RH AS 3.0 (ges-dfm).
Typically made available as /dev/sda1.
doc found by peter, fwd by emily about basic of cifs file operation.
cifs common internet file system
used by windows, and also has stuff like network browsing,
print services, authentication (NT). aka smb
Commonly a layer 7/6 (app/presentation) protocol, and usually
run over NTB.
smb server message block
samba unix open source implementation of some of cifs.
NTB NetBIOS over TCP
NetBEUI NetBIOS Enhanced User Interface (NetBios + precursor of CIFS)
SNIA Storage Network Industry Association
Coming up with CIFS 1.0 protocol w/ IETF.
Subset of current M$ CIFS, try to document it better,
and maintain for future.
WINS M$ refer this as the NetBIOS name server implementation.
Same function of DNS, but implemented totally differently.
Use lot of broadcast!
Run over NetBIOS (on top of whatever network protocol).
also see fs.ref, smb.conf
nmblookup -U -R
smbpasswd -j -r -Uuser%password
then start samba.
determine if secret used to join ntdomain is still good (security=server)
samba 3.0 use the "net" command:
net [method] [-d dbgLevelNum] join member -Uadministrator%password -S tileg-bdc1
member = add host as member host (not as pdc/bdc)
-S = target (window) server to use
[method] can be blank, it will auto detect
ads = XP style
rpc = nt4 style
ads = win95 style ?
-d 0-10 specify debug level info (spill to console), 0=none, 5=a lot, 10=unreadable. Try 3.
check whether domain participation is still valid
# no longer avail???
strace -o /tmp/output smbpasswd ...
to see what file it opens, has tendendy to open wrong smb.conf
list all doamin user
check that smb.conf is correct.
smbclient //10.0.71.231/cifs -W ntdom1 -Uadministrator%password
ftp like client to connect to nt-style share
smbclient -L 10.0.71.231 -N
list shares available from the given server
-N = force no ask password
update 2004/06/23, for samba 3.0, in tileg/hybridauto
create /usr/local/samba/lib/smb.conf file (see eg here for core elements).
add member host in PDC via server manager.
net join -Uadmin -S PDC-server # for security=server
sbin/smbd -D -s lib/smb.conf
# parameters are really default, but just in case samba have its own mind.
# show version
If using security=user, then may need to use smbpasswd -a to add user
Although it seems to authenticate via NIS if no smbpasswd entry.
quick and dirty config w/o domain fuss,
in smb.conf, set to use user level security mode (ie local list of samba user) :
security = user
add users to smbpasswd file as (user must be recognized os level user):
smbpasswd -a USERNAME
change existing user password:
location specified by smb.conf, typically /usr/local/samba/var
log.IP = NetBIOS ip to name resolution log, per each client machine connecting to the server.
log.HOSTNAME = smbd log for each connecting client after netbios name resolution.
log.nmbd = nmbd server process/status log
log.smbd = smbd server process/status log. level determined by smb.conf
# log level = 3 passdb:5 auth:10 winbind:2
# log level = 0 (default)
log level = 2
# workgroup = NT-Domain-Name or Workgroup-Name, eg: REDHAT4
workgroup = TILEG # NT4
# Security mode. Defines in which mode Samba will operate. Possible
# values are share, user, server, domain and ads. Most people will want
# user level security. See the HOWTO Collection for details.
#security = user # user = local passwd/smbpasswd file
security = server # need to join machine to nt domain
#security = domain # probably never used this.
# whether to use encrypted password
#encrypt passwords = yes # default = yes
