Applying Solaris Patches that Require Single User Mode

Some OS patches require single user mode and reboot. Does the standard Solaris plugin patch management handle this? If not, could I write my own patch component and simply add "init 1; patchadd; init 6" to the execnative?
Thanks - Jay

I can't speak about the Solaris plugin, unfortunately, but a single execnative call wouldn't cover what you're trying to accomplish. There's an RFE for the core SPS system to add this capability, but I don't know that it will be added soon. Remember that when you switch runlevels, a number of start and stop scripts are invoked, shutting down and starting up a number of services. To do what you want to do, you'd have to have a start script for the RA in runlevel 1. You'd also have to have a way for the RA to execute a command on startup which isn't possible today. There'd have to be a way for the MS to deposit a command for the RA to execute, restart the RA in runlevel 1, the RA would have to read the command on startup and execute it, then restart the RA to runlevel 3 (or 6, whatever is your default or previous runlevel). It's all doable, to be sure, but not with changes to the core product.

Unable to boot from cdrom in single user mode

I have lost the root password for solaris 9.So, I tried booting the system with solaris 8 CD in single user mode(i.e, at ok prompt, boot cdrom -s)
But I get the following error.
rebooting with command :boot cdrom -s
boot device :/pci@1e,600000/ide@d/cdrom@0,0:f file and args -s
boot:cannot open kernel/sparcv9/unix
Enter filename:[kernel/sparcv9/unix]:
Please let me know why is this error?.Is it becos the CD is corrupted?

Also, the particular Solaris 8 you've chosen could be a distribution that's too old for your particular computer's design.
For example, a Sunfire V440 would need Solaris 8 HW 7/03 or newer.
http://sunsolve.sun.com/handbook_pub/Systems/SunFireV440/Sun FireV440.html
Solaris 8 HW 2/02 would not work.
What model system, and what version Solaris are you trying to use?

Proper procedure for patching from Single User mode

Typically when I install a patch cluster from Sun, I do a sanity reboot from the console of the server using:
shutdown -y -g0 -i6
When the system comes back online, I log into the console again and then do:
shutdown -y -g0 -i0 (to go into OBP)
then
boot -s (to go into single user mode)
The procedure above was given to me from a Sun technician.
Then I install the patch cluster and reboot. It has come to my attention that Sun recommends breaking any mirrors between your disks before patching. I wanted to know what is the best way to do this for both Veritas Volume Manager and Solaris Volume Manager. For Veritas Volume Manager, I was thinking of going into the vxdiskadm menu driven utility and choosing the option to "Remove a disk for replacement" for the rootmirror disk and then after a reboot to check that the patches did not cause a problem, go back into vxdiskadm and choose the option "Replace a failed or removed disk" and select the rootmirror which should then begin to automatically resync itself to the primary rootdisk. Any comments on if this is a proper way to do this or if someone has a better method, I would love to hear it. I am assuming a system with just two internal disks: c1t0d0s2 and c1t1d0s2
Also, if anyone can comment on how to do this with Solaris Volume Manager or if it is required would be great also.
Thanks much for any advice.

I've often simply pulled one side of the mirror while the machine was shutdown. Since the mirror was valid prior to pulling, it will boot. If there's a problem, I shut down, swap disks, and boot from the untouched mirror. If no problem, I re-insert, reattach the disk to the diskgroup, then recover the volumes.
I don't know of any nice supported method of booting from an offline VxVM mirror that doesn't involve a very long series of steps. My method isn't supported, but it does work. If you have both disks in the machine at the same time though, it'll update the private regions. Don't do that until you're ready to sync up one way or the other. Test before doing it in production.
In any event, you should have a backup ready to go.

Patching zfs root in single user mode

Hi
I have to apply the Oracle recommended patchset to a server running on zfs root with zone roots also on zfs. The usual method of patching with Live Upgrade is giving some problems after the activation of the ABE. Can the patchset be applied to the server in the traditional single user mode
Any inputs would be appreciated

Yes, you can apply the patchset in single user mode, just keep in mind that your zones need to be bootable when patching as the patch installation will "partly" boot each zone when applying the patches. So if your zones rely on any NFS mounts etc, you will need to mount these first.
An alternative is to detach your zones during patching and then attach them using "zoneadm -z zonename attach -u" (or -U see the zoneadm(1M) man page for details on the differences).

How to mount USB & CDROM drives from single user mode - Solaris boot disk?

Hi All,
I need to carry out ufsrestore on a single newly replaced system disk (no redundancy / mirroring) from either USB or CDROM drives from the following steps:
( i ) GRUB => e, e, cdrom –s, Enter, b (boot from Solaris 10 x86 media).
( ii ) Choose menu 1 for Install Solaris Interactive Mode to reach single user mode.Below are the commands that I have tried in single user mode without success:
mount –r –F pcfs /dev/dsk/c1t0d0p0 /cdrom (after unmount Solaris CD)
mount: /dev/dsk/c1t0d0p0 is not a DOS filesystem.
svcadm –v enable smserver
svcadm: Pattern ‘smserver’ doesn’t match any instances
svcadm enable autofs
svcadm: Pattern ‘autofs’ doesn’t match any instances
devfsadm
devfsadm: mkdir failed for /dev 0s1ed: Read-only file system
mkdir /mnt
mkdir: Failed to make directory “/mnt”; Read-only file systemPart of the problem is due to the current READ ONLY filesystems which does not allow the creation of mount point such as /mnt.
I have been able to create both / root (/dev/dsk/c1t0d0s0) and /export/home (/dev/dsk/c1t0d0s0) filesystems with newfs that are awaiting for restore using ufsrestore.
The only option I am left with is to attach a secondary disk to install Solaris 10 on either of them before bring the system to multi-user mode so that service such as volmgt, autofs, volfs are available to access USB & CDROM drives.
Any suggestion on how to resolve this issue?
Many thanks,
Jack

Hi JKGN,
Is the directory a located under the root filesystem. ie /a? Are there any other mount point for say USB drive as well? I am not in a position to try it out right now but will get back
to you soon on whether /a exist or not.
Btw, the last thing I managed to do on this system at the time was added a secondary 1TB internal disk with the intention to restore both / and /export/home data onto this disk while
making use of all the disk device management services such as the following services only available in a fully installed Solaris system (both single & multi-user modes) installed on the
primary disk:
# svcs smserver

As a result, I am left with no option but the need to rebuild this system with only a single primary disk while in single user mode. However, the single user mode that I am in is the
one from Solaris installation disk with restrictive (_cannot create folder for mount point or running disk management utilities_) capability such as those services just covered, compared to one from a completed Solaris installation system with full access to all filesystems and utilities / commands in general.
I would very much value your assistance on how to mount both CD & USB in this restrictive limited Read Only OS (assume that it is running from memory) in order to get complete access to
the blank primary disk so that full restore with ufsrestore could take place.
Thanks in advance,
Jack

Solaris 10 single user mode

Hi,
I had just install a solaris 10 update 9 in the SUN v240. Do i need this same version of update in order for me to run in Single User Mode?
Or it can do also with the current latest version= solaris 10 update13?
Thanks,

Thanks,If you are asking whether you can boot that system using a CD/DVD of a newer release...
... then go do system maintenance tasks...
Yes, that is perfectly acceptable.
If you are asking whether you can boot that box using a CD/DVD of a newer release...
... then copy files fom that CD/DVD and overwrite existing files...
No, that would possibly muck up your system and you would have to wipe it and reinstall fresh.

Latest Patch cluster (Feb 11, 2010) unable to run in Single user mode.

Hi ,
This is my first post in this forum.
Hope you people will help to resolve the issue.
My issue - I have downloaded the latest patch cluster (Feb 11, 20100) and tried to install it from single user mode.
Nothing happened. I have waited for more than 30 mins, still no progres.
Then I killed the process, and tried to run it in Multi user mode (To verify any issue with extraction or file) -- Its working(and killed the process) !!!
Anyone facing this strange issue ?
Appreciate your help to complete the patching.
Thanks.
sas.

Hi,
If you're encountering issues with a patch cluster bundle your best bet is to contact [email protected] From the description it sounds like there may be a filesystem not mounted in SUM that the cluster is trying to patch.

Cannot mount USB disk in SIngle-user mode (solaris 10)

Hi all ,
I need some help please :
I can read/write to my USB disks when i'm in muti-user mode but when to I swith to single-user mode ( init S ), I cannot mount it.
in Single-user mode , i started volume management daemon :
#/etc/init.d/volgmt start
#volcheck
but i'm still not able to mount it.
I tried to mount manually:
#mount /dev/dsk/c2t0d0p0 /testpoint , i have this error: < mount : not a UFS magic number ( 0x0) , dev/dsk/c2t0d0p0 is not of this fstype.
My system recognizes the USB device though in single-user mode:
This is an output of #iostat -En

Hi ,
thanks for your advice. My problem is resolved.
The USB drive was actually a FAT filesystem.
so I did # mount -F pcfs /dev/dsk/c2t0d0p0:c /testpoint and everything went fine
I can read/write to my USB disks when i'm in
muti-user mode but when to I swith to single-user
mode ( init S ), I cannot mount it.
in Single-user mode , i started volume management
daemon :
/etc/init.d/volgmt start
#volcheck
but i'm still not able to mount it.It probably requires other items to be started
first.
I tried to mount manually:
#mount /dev/dsk/c2t0d0p0 /testpoint , i have
this
error: < mount : not a UFS magic number ( 0x0) ,
dev/dsk/c2t0d0p0 is not of this fstype.
Looks like it's assuming UFS. If this is a pcfs
filesystem, give it the type on the mount line.
# mount -F pcfs /dev/dsk/c2t0d0p0 /testpointYeah, this was the right command, I had to specify option < -F pcfs >.
but I read somethere on this forum i had to specify :c as the drive for FAT at the end of c2t0d0p0 , so the full command was:
# mount -F pcfs /dev/dsk/c2t0d0p0:c /testpoint

Automatic scrip execution on the console in single user mode on Solaris 10

Hi All,
On Solaris 8, I am able to launch my script automatically on the console when the system comes up into single user mode without having to enter the password. However, on Solaris 10, the script is display in the foreground on the console. When i do a ps -ef , I see the process running. Can someone please tell me how to get this to work on solaris 10?
To automatically boot the system into single user mode:
# svcadm milestone -d milestone/single-user:default
Files edited for this to work on solaris 8:
To login without a password:
# cat > /etc/default/sulogin <<EOF
PASSREQ=NO
CONSOLE=/dev/console
ALTSHELL=YES
EOF
# echo "/sbin/su -" > /sbin/rc1
(Solaris 10, I used rcS instead of rc1)
my script is called from the /.profile when the system comes up into single user mode.
I did the same on solaris 10, but no success.
Please let me know if you have any suggestions.
Thank you,
Brian

try
- add 'set -x' to your /etc/profile
- add 'set -x' to /etc/rc? scripts
- check /etc/vfstab for a nfs mountpoint not using 'bg'

Can't boot in Single User Mode or zap PRAM on iMac G5

I want to boot into Single User Mode in order to run Applejack to "clean" the system before applying Apple's latest security patches. So I hold down Cmd-S at start-up, but it has no effect; the computer boots normally into the Tiger GUI. Thinking that zapping the PRAM might help, I restarted while holding down Cmd-Opt-P-R. Same result: normal startup with no zap. I tried resetting the power management circuit by unplugging the iMac and depressing the power button. No effect.
Apart from the inability to do special boots, the system seems to be running just fine. Any ideas?
iMac G5 Mac OS X (10.4.8) 1.5 GB RAM

Ben F-
Not guessing yet. You did not provide what steps you have taken thus far and now I know.
I am thinking then that you have somehow set up firmware password protection.
At least the things that you describe are disabled if a password is set.

IMac 7,1 boot only in single user mode

Hi all
I've a colleague with the following problem... his iMac 20'' (iMac7,1) is able to boot ONLY in safe/single user mode (with shift key pressed during boot).
If he tries to boot normally, after the usual Apple logo screen he gets a blank (light grey) screen. No finder, no login screen.
We've tried this procedures:
- SMB reset
- PRAM cleared
- OS Reinstall (we've tried from Lion to Mavericks... actually there's 10.7.5 installed)... note that ALL installation procedure has completed successfully.
- tested the 1 RAM module installed (seems to be OK)
- tested the HD (no problems found)
Despite all these attempts, this iMac is booting well only if we press SHIFT during startup. All programs run well, wifi is working and online update too. If we reboot leaving it to restart normally (no key pressed) it shows Apple Logo for 1 minutes, then (after a black reset of the screen) seems to crash/stuck into an empty grey screen.
Is possible to identify which driver/kext is causing this problem? It can be an hardware problem? How we can fix it?
Thank you!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Wipe a HD via Unix in Single User Mode?

Is it possible to wipe a hard drive using diskutil or another method when booting up in Single User Mode? We routinely need to wipe drives and if possible, this would be the easiest.
I suspect because the OS that boots in Single User Mode is on that same drive will make this impossible.
Thanks in advance for your tips and comments,
Doug

Yes, you cannot erase an OS while it's 'hosting' the erasure. Single user mode is part of Mac OS X, so it's on the hard drive, not in the firmware or anything super-low-level like that. Oh well. So... you might be able to erase the vast majority of user, application, and even OS files, but it won't be complete and won't be 'as good as' a volume-format.
A couple alternatives come to mind (sorry if you know all this. Not trying to be pedantic or patronizing, just making sure you know your options).
We keep host computers around just for running wipes, backups, and diagnostics that cannot run from a drive holding the booted OS. You simply restart the to-be-wiped Mac holding the 't' key, connect it via firewire, and treat it as an external hard drive.
You could also just boot from a Mac OS X install disc and wipe from the copy of Disk Utility included on the disc. Better yet, throw a +bona fide+ copy of OS X onto a pocket hard drive, boot the victim-Mac from that (hold option while it is first starting up), and wipe the internal HD normally, now that it's not in use. You could maybe even use single user mode in the booting OS, like you'd imagined, and format from there (I'm not sure that would be faster than letting it boot normally, though, as you might have to use "dd" or some other similar low-level wipe method, as I don't think the frameworks required for Apple's cli "diskutil" are available in single user mode).
I haven't tried to use it on a Mac, but I have a 256 MB USB flash drive with, er, ['Darn' Small Linux|http://tinyurl.com/5md7t] on it for diagnosing Windows boxes. It runs a script on boot which, if you don't intervene to run utilities or what-have-you, will wipe all attached hard drives and shut down. I keep it locked up for understandable reasons, but its super useful just as a time-saver, booting most machines and beginning the countdown-to-wipe in under ten seconds.
Anyway, let us know what your goals and thoughts are.
Cheers, Joel

Getting Data Off Harddrive in Single User Mode

When my PowerBook G4 running 10.3.9 boots after the white apple screen I just get a blue screen and my mouse. I am able to boot into single user mode and get to the data on my harddrive. My other computer at home is a linux box so if I could just get the network going in single user mode I could ssh all of my stuff to the other machine. Is there any way to do this. Is there any other good way to recover my data?

Hi dsignoff,
   This is likely to be more difficult than it sounds. If the problem isn't a failed hard drive, you might have an easier time simply doing an archive-and-install. Of course any installation except a fresh install will preserve your home directory but an "update" installation stands a reasonable chance of not fixing the problem.
   Even if you do succeed in moving everything to the linux box, you will likely lose the resource forks and file metadata of the files.
   Of course even if you do try an archive-and-install, it never hurts to have some backup. I'm a bit rusty with Panther but I believe that it requires the following as a first step:
/usr/libexec/registermach_bootstrapservers /etc/mach_init.d
That actually starts quite a bit of the system, possibly including the part that is causing Aqua to fail to start up. (meaning that it too could fail) However, if the above command succeeds, the next step is to execute:
/sbin/SystemStarter start Network
You may also need:
/sbin/SystemStarter start NetworkExtensions
If all of that works, you should have enough services available to ssh to the Linux box and move files. Of course there is a chance that if you find the error messages of the process that is failing in the /var/log/system.log, we could actually recommend a fix for the system.

Back up files through Single user mode

Hello there,
it seems that I have problem with my hard drive. I tried to repair it with disk utility and the fsck command in Single user mode with no luck. The fsck command gives me the "Exited with signal 8" message and it won't start up the usual way or under Safe boot so I came to the conclusion to back up my files on an external drive and reinstall the system. I need step by step instructions how to back up the entire hard drive onto the external drive in Single User mode.

Do you have another mac with firewire?
Try target disk mode.
If you have a second Mac computer, you may want to try to copy over as many files you can. One way is to use target disk mode.
http://support.apple.com/kb/HT1661
http://lowendmac.com/misc/06/0710.html
This requires you to use your installation disk. With errors from fdsk, I do not think you will be able to copy all directories. I used a flash drive. A harddrive should be the same. To copy everything, use the directory /Volumes/Macintosh-HD
You may try to recover your data by booting up an installation cd/dvd and using the terminal.
You could try getting into the Unix command line interface and copy some files or directories.
You can copy files on the Unix command line interface if you placed the flash drive the USB port before powering on your machine.
Boot up your installation CD or DVD. To do this, place to the CD or DVD its drive. Power off the the machine. Hold down the c key then power on your machine. After you specify the language you will come to the installation panel. Do not install. Go to the top of the screen and click on the tools menu item. Click on Terminal to use the command line interface.
You should verify that the files have been copied correctly by trying them in another Mac before it the deleting the original.
*Here is an overview of the commands.*
Lets assume that the problem account has a short user name of mac.
#Copy directory "/Applications/Applescript files" to
# directory "/Volumes/Spotless/Applescript files".
# "Spotless" is my flash drive.
ditto -X -rsrc /Applications/Applescript\ files /Volumes/Spotless/Applescript\ files
#cd is change directory
cd /Volumes/COPYIT/answers/
# pwd is print working directory
pwd
#the ls command is for list
# l is long
# a to show hidden files. not shown in this example.
# F is type of file where / is directory
sh-2.05b# # Please note ls is the list command. l is a lower case L
sh-2.05b# ls -lF
Here is what these commands mean:
cd is change directory
pwd is a print working directory
ls is list
sudo is Super user do
# The sudo command will ask for your administration password. No characters will appear when typing your password. Press return when done typing.
cp is copy
copy a file example:
sh-2.05b#
sh-2.05b# cd /Volumes/Macintosh-HD/Users/mac/desktop
sh-2.05b# pwd
/Volumes/Macintosh-HD/Users/mac/desktop
sh-2.05b# cp -i answers.txt /Volumes/SpotMore
Will copy the file answers.txt in the directory SpotMore.
Some files have a space in the name. You need to escape. see example:
mac $ ls -l ~/"see it"
-rw-r--r-- 1 mac staff 3171 Oct 26 23:38 /Users/mac/see it
mac $
mac $ cd /Users/mac/Desktop/ttt\ html\ copy/
Do you know about tabing? Type in a few letters of a name then press the tab key. The computer will type out the rest of the name if it is unique.
The up arrow key will retrive the previous command. You the left arror and right arror keys to move around. Use the delete key to delete a character to the left.
<eol>

Powerbook -can't start up in single user mode or from CD-why?

My daughter was gifted a Powerbook (15"). I've upgraded it to 10.5.8. It has enough speed, (1.67 Ghz), 2 gigs RAM- but it is a sticky little machine- it freezes a lot. Froze twice during the upgrade, froze once during login, Froze once while trying to do a software update, froze once while trying to get into the system preferences. It freezes pretty consistently after 15-30 minutes or so, no matter what it's doing -if a program is running or not. I tried downloading AppleJack to run a diagnostic. That requires starting up from single user mode. I tried to do that , but the machine just opens to the login screen. I also tried running TechTool from the CD, and the machine wouldn't start up from CD either. What should I try next?

Try this one for some information.
