Dear Micheal,
Thanks for the solution again, it seems i dont
have any luck. I have patched the kernel with
BLIST_LARGELUN support I have tried all the options
given by u
still success is far away from me. I have made
these changes in the scsi_scan.c
{"IBM", "AuSaV1S2", "*", BLIST_LARGELUN |
BLIST_FORCELUN | BLIST_SPARSELUN},
{"HITACHI", "OPEN E*4", "*", BLIST_LARGELUN |
BLIST_FORCELUN | BLIST_SPARSELUN},
{"HITACHI", "OPEN E*18", "*", BLIST_LARGELUN |
BLIST_FORCELUN | BLIST_SPARSELUN},
{"HITACHI", "OPEN E*8", "*", BLIST_LARGELUN |
BLIST_FORCELUN | BLIST_SPARSELUN},
{"HITACHI", "OPEN E*36", "*", BLIST_LARGELUN |
BLIST_FORCELUN | BLIST_SPARSELUN},
I tried all the possible combination of
BLIST_SPARCE, BLIST_FORCE, etc.
I would like to know whether the LINUX works on SAN
envirnment. I am feeling it has its own limitation
in SAN.
If any one can help to solve my problem it will be a
great help.
To my strange experiance RedHat 6.2 with kernel
2.2-14 without SMP options works fine, withot LUNO
and without luns biengin sequence but we require
multiple cpu option
if RedHat 6.2 works fine i dont know why it is
not implemented in RedHat 7.X. I have tried allthe
possible Redhat vesions
Including the latest RedHat 7.3. To my suprise the
RedHat does not boot at all if the qlogic driver is
enabled at boot.
and have the same problem of LUN0 and sequence
LUNs. Is really Linux operating sytem is matured
enough to work as high end
server????
Pl can any body help???

% nft add map nat foo { type inet_service : ipv4_addr \; flags interval \; } should do the job

I am new to nft commands. I wish to use the map feature for port
forwarding. What I want to achieve is the following
Sftp incoming to port 2222 on the public IP to be port forwarded to
private IP on port 22. So what I found in the docs is this.
% nft add map nat foo { type inet_service : ipv4_addr . inet_service \; }
% nft add element nat foo { \
1100 : 192.168.1.2 . 5061, \
1101 : 192.168.1.3 . 5061, \
1400 : 192.168.1.4 . 5061 \
}
% nft add rule nat pre ip protocol tcp dnat ip addr . port to tcp dport
map @foo
So when I issue the first command I get the following error:
Error: unqualified mapping data type specified in map definition
When I issue the command: nft add map nat foo { type inet_service :
ipv4_addr \; }
It works just fine. I am at a loss as to why this is happening. The
reason I need the mapping is I need to add and remove port forwarding
rules easily with a simple command.
Any help would be greatly appreciated.

Hi Gobinda, if you have a consistent way to reproduce the issue, check
out `git bisect`: https://git-scm.com/docs/git-bisect

Hi,
I finally have a solution to this. We had the module for the QLA card
missing in the /etc/modprobe.conf
Also, for the HP EVA we are using, we had to add that in the
/etc/multipath.conf.
Thanks to all for the help.

Ok. Let me go step-wise.
First problem was multipath was not getting loaded at boot time, hence
you had to run multipath after every boot.
With the earlier suggestion, is this problem now gone?

I am not sure it it will help here but could you try this:
1. rename the exisiting multipath.conf to something (say multipath.conf.org)
2. create a new /etc/multipath.conf (blank file, do not copy it from
other multipath.conf.* files)
3. Copy the following content into it:
defaults {
user_friendly_names yes
selector "round-robin 0"
}
devnode_blacklist {
wwid 3600508e000000000ed7fb52911133c06
devnode "^(ram|raw|loop|fd|md|sr|scd|st)[0-9]*"
devnode "^hd[a-z]"
}
4. reboot
5. lsmod | grep dm (it must show dm-multipath loaded)
6. run multipath -ll
We had a similar issue where the multipath.conf file won't be read
whatever you do, bu it went away after creating a new file (instead of
copying). Though weird, worth giving it a try.
Regards,
Pradipmaya.

What does "chkconfig --list multipathd" show ?

This is what is happening as soon as the system comes up.
There are no multipathing devices created. Once I run the multipath
command only then the /dev/mpath/mpath# devices get created. It looks
like I am missing some thing when the system boots up. The system has
the multipathd start up script in /etc/rc3.d.
Any suggestions?

RHEL doesn't require anything other than the mere presence of
/etc/mulipath.conf to configure multipath devices. BUT there was a bug
where it was not able to properly use the /etc/multipath.conf file at
boot time when the file system (/var) is mounted read-only. So you get
device names based SCSI WWN. There is an init script that essentially
runs multipathd that renames the 'SCSI WWN' names to user friendly
names (apart from doing the job of path health check).
Make sure you start the multipath[d] rc script.

See my previous message. You need to enable the multipath rc service.

Hi,
I don't see any think like boot.multipathd. Is it some special rpm that
I need to install?

Attached document was shared by Chandra for installing RHEL/SLES on
multipath devices.
See if anything helps you.

Hi,
I have to run multipath command to recreate those devices. There is not
directory like /dev/mpath/ created on boot.

That is odd.
When the system boots up completely, do you see the multipath devices,
or you explicitly run the multipath command to make the multipath
devices show up ?

4.1. Installation instructions for SLES10
Note: This is tested on SLES10 SP1. If you have any other version, your
mileage may vary.
1. Install the OS in a device that has multiple paths. Make sure the
root device's "Mount by" option is set to "Device by-id" (this option is
available under "expert partitioner" as "fstab options").
2. Complete the installation. Let the system boot up in multiuser mode.
Make sure the root device, swap device are all referenced by their by-id
device node entries instead of /dev/sd* type names. If they are not, fix
them first.
3. Once booted, update /etc/multipath.conf If you have to make changes
to /etc/multipath.conf, make the changes.
Note: the option "user_friendly_names" is not supported by initrd.
So, if you have user_friendly_names in your /etc/multipath.conf file,
comment it for now, you can uncomment it later.
4. Enable multipathing by running the following commands
* chkconfig boot.multipath on
* chkconfig multipathd on
5. Add multipath module to initrd
Edit the file /etc/sysconfig/kernel and add "dm-multipath" to
INITRD_MODULES". Note: If your storage devices needs a hardware handler,
add the corresponding module to INITRD_MODULES, in addition to
"dm-multipath". For example add "dm-rdac" and "dm-multipath" to support
IBM's DS4K storage devices
6. Run mkinitrd
Note: You can uncomment the user friendly name if you have commented it above.
7. Reboot
The system will come up with the root disk on a multipathed device.
Note: You can switch off multipathing to the root device by adding
multipath=off to the kernel command line.
4.2. Installation instructions for RHEL5
Note: This is tested on RHEL5 U1. If you have any other version, your
mileage may vary.
1. Start the installation with the kernel command line "linux mpath"
* You will see multipathed devices (/dev/mapper/mpath*) as
* installation devices.
2. Finish the installation.
3. Reboot.
* If your boot device does not need multipath.conf and does not
* have a special hardware handler, then you are done. If you have
* either of these, follow the steps below.
4. Once booted, update multipath.conf file, if needed.
5. Run mkinitrd, if you need a hardware handler, add it to initrd with --with option.
* # mkinitrd /boot/initrd.final.img --with=dm-rdac
6. Replace the initrd in your grub.conf/lilo.conf/yaboot.conf with the
newly built initrd.
7. Reboot.
The system will come up with the root disk on a multipathed device.
Note: You can switch off multipathing to the root device by adding
multipath=off to the kernel command line. Note: By default, RedHat disables
dm-multipath by blacklisting all devices in /etc/multipath.conf. It just
excludes your root device. If you do not see your other multipath devices
through "multipath -ll", then check and fix the blacklist in
/etc/multipath.conf

I used the /dev/mapper/mpath# also in the fstab but that did not help.

Without the /etc/fstab, this is my hunch: you are using /dev/mpath
in /etc/fstab. Try /dev/mapper instead.

Without the /etc/fstab, this is my hunch: you are using /dev/mpath
in /etc/fstab. Try /dev/mapper instead.

Hi,
Can you please provide me with the process to add the dm-multipath in
mkinitrd?
I am sure that those devices are not getting loaded.
Also regarding the fstab, I earlier had the LVM for those LUNs. But
since I faced the problem of system not booting up, I removed them for
the time being.
Thanks,
Varun Nath

Could you please share the fstab entry (also what you are trying to add
to it).
When are you getting the problem (not recognizing devices), is it at
boot time?
I am new to Linux but my hunch is when you are booting, as multipath
is loaded, these devices are not getting recognised. In this case you
might want to mkinitrd with dm-multipath.
Thanks,
Pradipmaya.

Hi,
I am trying to configure multipathing on Red hat 4 update 6 64 bit.
Below is the list of RPM I have installed
rpm -qa | grep mapper
device-mapper-1.02.21-1.el4
device-mapper-1.02.21-1.el4
device-mapper-multipath-0.4.5-27.RHEL4
The hardware is Sun x4600 and I am using QLA cards. The system has two
LUNs presented to it of size 10 GB and size 90 GB
There is a problem when I configure file system on it. I am able to
access and mount the file system. But when I add those entries in
/etc/fstab, the system would not recognize those devices.
Below is the output from multipath command
multipath -ll
mpath5 (3600508b40010541d00009000065d0000)
[size=90 GB][features="1 queue_if_no_path"][hwhandler="0"]

Hi All,
I am planning to do my acadamic project in wireless mesh. Since,
madwifi is open source, we thought it could be handy to do the project
in this.
Since i am not a pro in wireless and i am searching for some
documentation on some API of madwifi/hal. Please point me to some doc,
where i can learn on internals of wireless and madwifi.
Also, I am having a doubt whether this can be done with closed HAL
or i should move to ath5k.
Thanks,
Ramachandran m s

I think the correct solution is to use an excrypted mount, and issue the
mount command manually with the question in user space. There's no code
to ask for input, nor anyway to positively decide which connected
terminal is the terminal to ask.

No, since the kernel has no way to ask for input. Imagine a two-seated
machine with two keyboards, mice and monitors, one terminal at each serial
port, three users logging in using XDM and one disconnected screen session
on tty6. Who's going to be asked? And in case of X11 or XDM: How should the
kernel authenticate to the user's screen?

Which OMAP board/custom-board are you using? Kernel Version? Are you
talking about USB-Webcam?

Hi,
I am new to OMAP, USB and Linux. I am trying to capture webcam image from
OMAP that runs on linux. What would be the easiest way to go? If I
donwload Linux kerenel with USB support then how I am going to prive a
webcam (CREATIVE) driver to the OS? Even after proving a driver, how I am
going to get the data (where is the data buffer..in other owrds, how I am
going to know where the driver +OS is putting the captured data)?
Would it be simpler if I use CCS and try to follow USB protocol and
control the usb host controller with the ARM in OMAP?

I have the partitions for separate / and /usr for domain-1
but no luck with domain-1 boot success. Domain-0 error about sharing
partitons across domians is gone though. So, I would like to know
how does exactly domain-1 boots(or will) based on the info in it's
/ partition or domain-0 / partiotion.
1. Does it use the /boot/grub info of either dom0 or dom1?
2. Does it use the /etc/fstab entries of dom0 or dom1?
Any other ideas involved that might significant here?

does dom0 still have /dev/hda8 mounted?
unmount it.
how does dom0 have /dev/hda6 mounted?
if it is mounted read/write, mount it read-only.
for all partitions:
If you want to mount a partition rw in one domain it *can not* be
mounted in any other domain
If you want to mount a partition in multiple domains it has to mounted
*read-only* in *all* domains.

Addition to my message:
I copied from hda5 to hda8 the relevant directories using cp -pr
(bin boot dev etc initrd lib home opt sbin tmp var), couldn't copy
proc (is it created and populated at boot time?).
Command
xc_dom_create.py -Dvmid=1
results in error:
...

1. mke2fs /dev/hda8
2. mount /dev/hda8 /mnt
3. mkdir /mnt/mnt /mnt/proc/
4. cp -a /bin /boot /etc ... /mnt (everything but /proc)
presto, an exact copy. I tend to do this stuff from single user mode, but it
might not be necessary.

I am back to trying xen-1.2 and need a little(?) help.
Hard disk config:
hda1 (primary swap), hda2(extended): had5(/, 1Gb), hda6(/usr, 2Gb),
hda7(1Gb), hda8(1Gb)
Installed Fedora-core-1 using / and /usr
Downloaded precompiled xen-1.2-install.tar.gz
Installed it
Able to boot domain-0
How do I put root partition info for dom1 on partition hda8
I tried dd if=/dev/hda5 of=/dev/hda8 bs=1024
aborts with I/O error after copying the file system
(mount says that it is invalid FS etc..)
Is there another way? Just want to see if I can boot one more
domain other than domain-0.

It doesn't like one of the words you typed in the command you entered.
Since you didn't tell us what the command was, I can't tell you which word it
was, but hopefully this is enough of a clue for you to work out the problem.

Hi Pius,
This is the kernel development list. Please ask future questions in a

Hey,
I am using the WOLK 4.3 patchset and cpufreq seems to be working
fine except for 2 problems. the /pro/sys/cpu interface seems to be
broken, the speed-max and speed-min are both always 0, also i cannot
change cpu frequency by writing to /proc/sys/cpu/0/speed and speed only
correctly (at least i think its a correct value) displays the speed
after i write something to /proc/cpufreq. The other problem is that i
think the policy setting in /proc/cpufreq is broken, when it is set to
performance it simply sets the speed to the the maximum and keeps it
there and when on powersave is simply sets the speed to the minimum and
keeps it there. Any help would be great, thanx.

Yes, you can match the source/destination IP address and/or source MAC
address.
Examples:
# iptables -A FORWARD -s 10.20.30.40 -j REJECT
# iptables -A OUTPUT -d 10.12.13.14 -j LOG
# iptables -A FORWARD -m mac --mac-source 00:01:23:45:67:89 -j ACCEPT
# iptables -A FORWARD -m mac --mac-source ! 00:01:23:45:67:89 -j REJECT
Please read
# iptables -m mac --help
# iptables --help
And whatever comes to your mind, the modules have their own help messages.
# iptables -p tcp --help
# iptables -m state --help
etc...
Regards,
Maciej

You can use MAC match option

Hi,
I'm a student and wondering if there is anyone out there could send me full
instructions step by step on how to successfully install Linux on a SGI
Indigo2 machine and what particular version of Linux is needed? Thanks for
any help.

It's a good idea to put this *after* your rules, to avoid any period of time
when the kernel's forwarding packets, but without a ruleset loaded...

The -s 0.0.0.0/0 is redundant.

Please do this as an explicit ACCEPT rule for *outbound* packets which do not
match HTTP, and have a default DROP policy on the FORWARD chain (so you block
anything trying to come in).
ie:
iptables -P FORWARD DROP
iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD -p tcp --dport ! 80 -o $extIF -j ACCEPT

Please verify that your portmapper is running, server and client:
http://nfs.sourceforge.net/nfs-howto/server.html#PORTMAPPER
and this exactly describes your problem:

Hi,
Are you sure that portmap is running on the server (and client), and that
your ip is allowed ?
Is the mounts programm listed in
$ rpcinfo -p <server>
?

Dear Micheal,
Thanks for the solution again, it seems i dont
have any luck. I have patched the kernel with
BLIST_LARGELUN support I have tried all the options
given by u
still success is far away from me. I have made
these changes in the scsi_scan.c
{"IBM", "AuSaV1S2", "*", BLIST_LARGELUN |
BLIST_FORCELUN | BLIST_SPARSELUN},
{"HITACHI", "OPEN E*4", "*", BLIST_LARGELUN |
BLIST_FORCELUN | BLIST_SPARSELUN},
{"HITACHI", "OPEN E*18", "*", BLIST_LARGELUN |
BLIST_FORCELUN | BLIST_SPARSELUN},
{"HITACHI", "OPEN E*8", "*", BLIST_LARGELUN |
BLIST_FORCELUN | BLIST_SPARSELUN},
{"HITACHI", "OPEN E*36", "*", BLIST_LARGELUN |
BLIST_FORCELUN | BLIST_SPARSELUN},
I tried all the possible combination of
BLIST_SPARCE, BLIST_FORCE, etc.
I would like to know whether the LINUX works on SAN
envirnment. I am feeling it has its own limitation
in SAN.
If any one can help to solve my problem it will be a
great help.
To my strange experiance RedHat 6.2 with kernel
2.2-14 without SMP options works fine, withot LUNO
and without luns biengin sequence but we require
multiple cpu option
if RedHat 6.2 works fine i dont know why it is
not implemented in RedHat 7.X. I have tried allthe
possible Redhat vesions
Including the latest RedHat 7.3. To my suprise the
RedHat does not boot at all if the qlogic driver is
enabled at boot.
and have the same problem of LUN0 and sequence
LUNs. Is really Linux operating sytem is matured
enough to work as high end
server????
Pl can any body help???

Dear Michael,
Thanks for the solution, but my problem still
remains unresolved. I added the following lines to
scsi_scan.c and recompiled
{"IBM", "AvSaV1S2", "*", BLIST_FORCELUN |
BLIST_SPARSELUN},
{"HITACHI", "OPEN E*4", "*", BLIST_FORCELUN},
{"HITACHI", "OPEN E*18", "*", BLIST_FORCELUN},
{"HITACHI", "OPEN E*8", "*", BLIST_FORCELUN},
{"HITACHI", "OPEN E*36", "*", BLIST_FORCELUN},
{"HITACHI", "DF400", "*", BLIST_FORCELUN},
{"HITACHI", "DF500", "*", BLIST_FORCELUN},
{"HITACHI", "DF600", "*", BLIST_FORCELUN},
the out put of the scsi venders are as follows
cat /proc/scsi/scsi

If u can help me out where i am doing the mistake
it will be of great help.
plfind the enclosed scsi_scan.c file. Is there any
method or commands to find out BLIST_FORCELUN is
enabled?
Thanks and regards

2.4.18 needs a hint added to drivers/scsi/scsi_scan.c
to allow it to scan targets with sparse luns.
Look in /proc/scsi/scsi for the vendor and model and
add them into the device_list array in scsi_scan.c
...
{"<VENDOR>", "<MODEL>", "*", BLIST_SPARSELUN},
If you don't configure lun 0, you may have to use
BLIST_FORCELUN which if my understanding is correct
will force scanning of all luns.
I hear there is some REPORT_LUNS code that will
eliminate the need to do this, although don't know
which kernel has it.

Dear sir,
we have SAN environment with hitachi storage box
and brocade switch. we are trying to install Linux
with qlogic HBA card. we are facing strange
problems
1. If we disable LUN 0 we will not be able to see
any LUNs on liunx machine
2. If we enable LUN 0 we can see all the LUNS
but it should be in sequence i.e LUN0 ,1,2 , 3 etc
if we disable LUN 3 we will not be able to see LUNS
4 and the rest
Is the above things are limitation of linux.
Linux machine is running with 2.4.18 kernel
Is there any solutions for these problems?
Thanks and Regards
Manjuanth

You might want to see if my patches for MVME2600 and especially the
bootloader part in arch/ppc/prepboot help. They are available at
ftp://vlab1.iram.es/pub/linux-2.2/
you will still need to perform the early setup of the CPC700, modify
the UART address etc...but the code includes things like PCI resource
allocation and is flexible enough to be adapted to a variety of PCI I/O
base addresses, memory offsets etc...
Regards,
Gabriel.

Hi,
I need to port Linux on our hardware with
603e processor and cpc700 MMU. There is no disk support.
We do have flash ROM and ethernet on board.
Can anyone suggest a site I can download this port OR
a close match ?
Regards
Pravin
