DOS-family networking (netware too I think) uses the UNC convention:
\\\[\path]

Various parts of *X (including shells) escape characters, using the "\"
as the key to flag when escaping is intended, so one has to type "\\" to
mean "\".

Sometimes, escaping can be done more than once.

To avoid this, Samba and attendant software allows "/" to be used
interchangeably, in UNC filesystem names.

Apart from syntax checkers, OS/2 (and I think Windows) also allows "/"
to mean "\" in filesystem names.

No, that just means the smbfs kernel module has been loaded, and it's one that 
(for whatever reason) isn't going to be supported by Novell if you have a 
problem with it, or if Novell support thinks that it is causing another problem 
elsewhere.



I'm sure cifs is supported.

It is possible to mount smbfs from fstab. From your line i see that you
have a ":" to much and some of the "/" changed to "\". The line should
look like this:

\\ipaddres/dirname /dirname smbfs username=testid,password=testpw 0 0

And ofcourse, if you want it to automount at boot you change the last 0
to 1.



Here are two correct mount commands. Note that cifs is the successor to
smbfs:
mount.cifs  coco\\profile /mnt/coco/ --verbose -o
user=administrator,password=**,ip=10.0.0.253,domain=class.corridors
mount -t cifs  coco\\software /mnt/coco.software --verbose -o
user=administrator,password=**,ip=10.0.0.253,domain=class.corridors


This works too:
mount.cifs //coco/profile /mnt/coco/ -o
user=administrator,password=**,ip=10.0.0.253,domain=class.corridors

The arguments on the mount commands here should appear in fstab if
that's what you are using.

The credentials can be picked up from a file, so as to maintain
confidentiality.

Mostly, I prefer to not use backslashes so as to avoid hassles with
programs that think they should be escaped and so reduce two to one,
potentially several times.


Note, on SLES10 (and probably 9) you should be specifying cifs, not
smbfs; smbfs hasn't been maintained for some time.

I guess I buy that answer to a point. If the driver receives an error code,
then providing some additional context around "Adapter returned: x"
would be a lot more helpful to you than just a bare error code. Since the
operation of these adapters is a Deep Dark Secret, we could do a lot more to
tell you what happened if you told us the context of the problem, regardless
of the source of the problem.

Example: "Adapter returned: x0a" tells me almost nothing that you would find
useful -- you're going to have to ask me to trace stuff and send you more
details. "Adapter returned: x0A (PORT_NAME_MISMATCH) when initializing
adapter, first use". That tells me something I can use to help you
understand the problem (and maybe solve it myself). You know what the
various codes mean, or you can lean on the hardware guys to find out. Even a
simple enumerated type lookup like the one shown above would be better than
what we have now.

No, that just means the smbfs kernel module has been loaded, and it's one
that (for whatever reason) isn't going to be supported by Novell if you
have a problem with it, or if Novell support thinks that it is causing
another problem elsewhere.

Re: smbfs mount ?

[Erik N Johnson]

So again, to clarify, two questions:
1. The checkpass value (field 6) has no bearing on whether a given
volume will be automatically mounted and determines only the order in
which fsck will examine the volume (if at all.) Is this correct?

2. The ONLY way to specify that a given fstab entry should NOT be
mounted at boot time is to specify the NOAUTO option in the options
list (field 4.)  Is this correct?

Sorry to be redundant but I want to make absolutely sure my
understanding is correct.

Re: smbfs mount ?

[Mark D Vandale]

This is the format in the last /etc/fstab I tried.  I started out using the
credentials option and changed to specify the username and password just to
make sure I didn't have something wrong with the file that contained the
username and pw.  The uid, gid, fmask and dmask was added this last time as
well, before I had not specified those.  This format looks like what
everyone  has specified except the 0 0 at the end.  I had found this
message in one of the logs and wasn't sure if it was related to this
statement in /etc/fstab:
In var/log/messages that says  "kernel:  smbfs: module not supported by
Novell, setting U taint flag.

ipaddress/p2dev  /p2dev   smbfs
username=xxx,password=xxx,uid=emxpkid,gid=emeddev,fmask=774,dmask=777,rw
0 0

Nothing special about Linux or about zLinux regarding /etc/fstab.
I think several have simply omitted details when trying to answer this

#1,  YES,  you can mount smb via /etc/fstab (and not only manually)


#2,  NO,  there is no difference between /etc/fstab on zLinux
and other Linux
/dev/to/mount  /place/to/mount/it  type  options  backuppass  checkpass

Re: smbfs mount ?

[Erik N Johnson]

I'm confused by this thread.  Is there a special behaviour of fstab
specific to z/Linux?  On every other UNIX or UNIX-clone system I have
ever used including Linux on the x86 and powerpc platforms, the two
integer values at the end of an fstab config line have nothing
whatever to do with automatic mounting.

instead, all entries are automatically mounted at boot unless the
NOAUTO keyword is given.

the numbers, as best I understand, represent the following:
field 5 (first integer field) specifies a dump frequency.  for more
info see man -s8 dump
field 6 (second integer field) specifies fsck order.
this is very very simple
a value of zero means "do not examine this volume on boot"
a value of one means "this volume must be checked first" this option
should be used only for the root filesystem
a value of two means "this volume may be checked at any time
subsequent to the root volume"  typically this means that logical
volumes on the same physical volume are checked in series, volumes on
distinct physical hardware will be checked concurrently, obviously
because of hardware constraints.  afaik it is possible to specify
values >2 which would then indicate, these volumes should be checked
only after all volumes with an fs-check value of 2, and so on and so
forth.

Please, if I am in some way in error, somebody let me know!  I'd hate
to discover that my *nix boxen were doing bizarre things at boot up.
I can tell you this though, all my volumes mount at boot except for
optical drives and one nfs mount (specifically /usr/home on my
fileserver which automounts on my Linux and BSD boxen but not on my
Mac, I do have an fstab entry on my mac, bearing the noauto keyword,
as well as an fs-check value of zero (there should be no need to fsck
network mounts as they are checked when the providing host boots. I
don't even know if fsck works at all on network filesystems, as I
believe it bypasses the typical VFS abstraction and works on the
physical hardware directly.)

Again, if I am in error, please let me know!

Re: smbfs mount ?

[Scott Rohling]

Works fine from /etc/fstab..   just use the same format as the mount (not
sure what the colon was about):

//192.168.20.2/Media   /Mediasmbfs   ro, blah blah

Sure you can do that, although it's not recommended to code the userid and 
password in /etc/fstab itself.  (See credentials in "man smbmount".)  Did you 
really have the colon between the ipaddress and dirname in /etc/fstab?  That 
isn't likely to work.

Re: smbfs mount ?

[Amelia Nilsson]

It is possible to mount smbfs from fstab. From your line i see that you
have a ":" to much and some of the "/" changed to "\". The line should
look like this:

\\ipaddres/dirname /dirname smbfs username=testid,password=testpw 0 0 

And ofcourse, if you want it to automount at boot you change the last 0
to 1.

Best regards,

smbfs mount ?

[Mark D Vandale]

Can smbfs be mounted from /etc/fstab ?  I can issue the cmd "mount -f
smbfs //ipaddress/dirname  /dirname username=testid,password=testpw"  and
get the smbfs mounted but I can't get this mounted by adding a line in
the /etc/fstab .  The format in the /etc/fstab is more like -->
//ipadress:/dirname   /dirname  smbfs ro,username=testid,password=testpw  0
0   Is this possible from /etc/fstab or do I need to do this from somewhere
else ?  This is SUSE SLES10.

Thanks,

Re: ganglia, libconfuse RPMs?

[John Dome]

I have built ganglia 3.1.1 for SLES 10 SP2, fairly straightforward.

Everything is working pretty well, the only issue I have identified is that
cpu speed is not reported.  Actually a question to the forum, is it
possible
to query that information from Linux?  If not what about within VM?

Re: Problem getting a SAN device connected to our Linux

[Robert J Brenneman]

Does the storage device allow you to define the type of host that is
connecting to it?

I know we have to specify a zSeries Linux host in the IBM type storage
boxes since it uses a different lun number format than xSeries Linux
does on the wire. If you have a host type field on the storage
controller try changing it to a different type. It could be something
wacky like a HPUX system or AIX that ends up working since those may
coincidentally use the same lun number format as zSeries Linux.

It's just something else to try while you wait for the vendor to get
back to you.

Just one thing to try:

echo  0x > unit_add

It should be smart enough to pad it out, but just to be sure...

If that works - make sure you specify it that way in /etc/zfcp.conf

Problem getting a SAN device connected to our Linux

[Bauer, Bobby (NIH/CIT) [E]]

 We have an older model SANs device that we are not having much luck with 
connecting to our Red Hat Linux (5.3) under z/VM 5.4. We specified the LUN as 0 
on the SANs device. It is a CorData SAN and we are contacting the vendor.
All seems to go well until I try to echo the LUN into unit_add


Following the Red Hat Installation Guide for adding FCP devices dynamically:

The logs in the SANs device don't show anything. The lszfcp command reports a 
status of "0x4500092e". Any insight or what steps to take next would be 
appreciated.

Hey Gary,

I have used this many times on linux and window hosts.

'vncserver' starts it
You can check for the listener port by checking netstat -an | grep tcp | 580*

Hi, Gary.

Yes, I've gotten it to work before.some thoughts:

1) any firewall issues?
2) I believe for the Windows based VNC clients, Java needs to be enabled on the 
workstation
3)what Linux VNC server and distribution are you using?

David,

I agree with you. But most of the error codes indicate programming
errors, which should be reported to us. It is an ongoing effort for us
to identify those "real" error codes, which are not caused by code
problems, and to come up with a meaningful message for them (like the
error code 0xf6 discussed in this thread).
