How to limit /var/adm/wtmpx and /var/adm/lastlog

Hi,
As many others I have a problem too with these files growing indefinitely.
I wanted to know if there is any system configuration or system program to limit or trim the size of these files.
I am OK if the oldest records get purged, but I don't want these files to grow indefinitely.
I appreaciate any suggestions and help.
Thanks

I think the easiest would be to use 'dd' to copy the file to a temporary area and then back again:
dd if=/var/adm/wtmpx of=/tmp/wtmpx.save bs=372
dd if=/tmp/wtmpx.save of=/var/adm/wtmpx bs=372 skip=$number_of_blocks_to_skip
The variable $number_of_blocks_to_skip is simply an arbitrary number you're comfortable with. You can build that up by using 'wc' to find the number of lines (blocks) in the file:
wsize=`wc -l /var/adm/wtmpx | awk ' { print $1 } '`
number_of_blocks_to_skip= `expr $wize - 1000` (this will ensure that the skip is until 1000 blocks from the end)

by commenting above line in initttab file would stop messaging, is this would have any adverse affect on the database. As its a production server, so i am really taking time to resolve it. Your suggestions are welcome. If there is no harm in commenting the above line then i would go forward to comment that line.

How to limit back up time and content

What service are you using to perform the back up - Verizon cloud or another (Google, OneDrive, etc)? What phone do you have?

/var/adm/wtmpx file size control ?

Hi :)
The /var folder on our DNS server has reached > 90% capacity and is rising 1% a day. ls -ltr shows that the most current files are /var/adm/wtmpx and utmpx as well as lastlog and messages. Is it possible to cap the size of the wtmpx file, which seems to be the file that is growing the fastest ?

Certainly, there are a couple of ways of doing this;
If you want to save the old data (and you might want to if its a firewall), you can always copy the wtmpx file to something else, and then copy /dev/null over wtmpx:
# cp /var/adm/wtmpx /var/adm/wtmpx.0
# cp /dev/null /var/adm/wtmpx
Then its of course a good idea to compress the old file.
If you don't want to save any data, just copy /dev/null to wtmpx.
A somewhat more complicated way of doing this is to hack the wtmx file and only save, for example, the 1000 last lines. This can be done with the /usr/lib/acct/fwtmp command.
The fwtmp command lets you export the wtmpx file to something human readable (and editable), which you then may edit and convert back into your wtmpx file.
However, there are a few bugs in this commands, so it will not work without the latest 'n' greatest fwtmp patch: 116943-02.

[SOLVED] Cloning boot and var partitions to a new drive for booting

Ok first of all here's my setup:
fakeraid (dmraid) / and home on an OCZ Revodrive
boot with GRUB on a flash drive (since fakeraid doesn't support grub)
var and downloads/media folder on a 500GB WD Caviar drive
When I originally installed Arch I had the Caviar drive in my home server in a RAID5 array, so that's why I opted to install boot and grub on a flash drive simply for booting. Now that I have the drive in my desktop I've cloned the flash drive's partitions and MBR using dd:
#dd if=/dev/sde of=~/MBR.img bs=512 count=1
#dd if=/dev/sde1 of=~/boot.img
#dd if=/dev/sdc1 of=~/var.img
I then backed up my downloads/media partition, then removed the partition table, then used dd to put the img files on the Caviar drive.
#dd if=~/MBR.img of=/dev/sdc bs=512 count=1
#dd of=~/boot.img of=/dev/sdc1
#dd of=~/var.img of=/dev/sdc2
I also created labels for the filesystems and put those in fstab.
I'm able to mount both partitions, however I can't boot from the drive. I get a 'grub hard disk error' (no error number) when I put it as my first drive in the BIOS.
I can still use the flash drive as the first hard drive in the BIOS and boot from it, then it mounts the dmraid root partition and boots successfully. It is also able to mount the var and boot partitions in fstab.
Basically the only problem is that the MBR is somehow wrong. I then tried booting back into an Arch live USB and installing GRUB from the prompt:
grub
grub>setup (hd4,0) (in this case the Caviar drive's boot partition was /dev/sde1
So essentially what I'm asking is how GRUB handles the MBR. Is it specific to the partition table of the drive in which it resides when it's originally installed? For instance, since I had an 8GB flash drive with 2 partitions when I installed GRUB, is the backed up MBR no good for a 500GB drive with 3 partitions?
I have everything backed up so I can start with a fresh /boot and /var if need be....I'm just not sure where to start.
Thanks in advance.

Sorry, I forgot to mention that I tried to install GRUB from the GRUB shell in a live Arch USB. It failed on a few non-critical parts, and succeeded on the last part. I'm going to try again shortly, possibly I did something wrong. GRUB is able to find the stage files using:
#grub
grub>find /grub/stage1
grub> find /grub/stage1
(hd0,0)
(hd5,0)
grub>
(hd0,0) is the desired boot drive, while (hd5,0) is the current bootable flash drive with /boot and GRUB installed.

I'm using dmraid, so just to be clear I've configured the raid using:
#modprobe dm_mod
#dmraid -ay
Then I saw the array stored in /dev/mapper/silXXXXX. I then created partitions for /boot, /, and home. At that time I was hoping to get GRUB working with the AUR package grub2-dmraid. I wasn't able to get it working for some time, so I just went ahead and installed boot and GRUB to a separate USB flash drive.

Also I don't have a /proc/mdstat. That's only for mdadm RAID setups, right? It's been quite some time since I've used mdadm so I can't remember.
EDIT:
So I booted into a live Arch USB and entered the grub shell. I ran:
#grub
grub> root (hd3,0)
Filesystem type is ext2fs, partition type 0x83
grub> setup (hd3)
Checking if "/boot/grub/stage1" exists.....no
Checking if "/grub/stage1 exists.......yes
Checking if "/grub/stage2 exists.......yes
Checking if "/grub/e2fs_stage1_5 exists....yes
Running "embed /grub/e2fs_stage1_5 (hd3)".....25 sectors are embedded.
succeeded
Running "install /grub/stage1 (hd3) (hd3))1+25 p (hd3,0)/grub/stage2 /grub/menu.lst".......succeeded
Done.
Last time I recall more errors than this, then it reporting that one was a non-critical error, so I think the problem may be solved. More to come.

/var/spool/imap and Time Machine

Hi,
after upgrading my G4 Mini from 10.5 Server to 10.5.1 Server, the machine didn't boot any more.
When trying to restore from my Time Machine volume, I figured out that /var/spool/imap is not being backuped up by Time Machine.
I double checked on another 10.5 server, same thing here.
Any ideas to make Time Machine also copy /var/spool?
Since /var/imap is on Time Machine - the db files in that directory do not contain eMail bodies, right?
Thanks for any help - I don't want to lose my 5 year email archive...
Cheers from Germany,
Peter

I just did another Time Machine restore and this time I ended up with /var/spool/{postfix,imap} not existing and nothing working. This appears to be a common problem. I'm trying another restore from an earlier backup.
I didn't have any luck with other restores, but I think I understand why now. Previously when the restore worked, the server was in Standard mode. A week or two later I ran into OpenDirectory problems and the Apple support guy walked me through switching to Advanced mode and how to rebuild the OD master. Everything seemed to be fine, but the Time Machine backups were no longer backing up the data in /var/spool and several other important directories. When it came time to restore, I had nothing but problems.
It appears the "magic" works in Standard mode but not in Advanced. I guess this explains a "Not Used" in the Advanced column on page 27 of the getting started book. During Time Machine backups in Standard mode, a command called SBSBackup is run to suspend services nicely then backup service related files into a /.ServerBackups directory. When the backup is done, another SBSBackup command is run to remove the /.ServerBackups directory (as it will have already been backed up via TimeMachine.) If a restore is done, the /.ServerBackups directory is what is used to repopulate things like /var/spool, etc.
Before anyone gets interested in reinstalling with Standard mode just to get recoverable Time Machine backups, I should point out that this SBSBackup has some "interesting" side effects. Because Time Machine runs hourly and the SBSBackup stops services, occasionally it's noticeable that something isn't running. Clients running Mail will frequently get the grey lightning bolt when they go to check mail and the service is down during the backup. Also, I think one of the times my server was corrupted was when the machine was rebooted while a /.ServerBackups was being created just before a backup. After I rebooted, some configuration files were missing and I suspect that the boot process checked this directory to automatically do restores of certain services then failed halfway through.
To summarize, anyone using Advanced mode will have to rely on something other than Time Machine for full system backups.

Instance name and Var for Input Text fields

I have several Input Text fields, as a form, linked to a PHP
script for which I require Var's for each field.
But I also need Instance names for each field, so I can fix
the tabIndex.
Yet, everytime I test my movie, the text fields have their
Paths (_level0.fName) written in them.
They are normally blank, and I've tried putting in some text
of my own, but the Var name is still displayed in the text fields.
Is there any way I can stop that from happening, and keep
both the Instance names and Var's in-place.
As far as I know, I need both the Instance name (for the
tabIndex) and the Var (for the PHP script) or is there a way that
the tabIndex and PHP script will work with either of the two?
Thanks
Chaz.

Can you use a different name for ‘instance name’
and ‘var’? That seems to solve the problem but I
don’t know if that helps you in your situation.
For an example;
Instance name: test_txt
Var: test

How to avoid the hard limit of 100 column and items per page?

I have created a Form on a Table with Report. I need to create/edit approximately 175 items. The items on the Form have a limit of 100 column and items per page. What is the best way to carry the remaining items to another Form and doing an insert or update? or is the 100 column limit on the insert/update per table as well?
Thank You.

Hi Rick,
The 100 item limit is on a page, not a table, so you shouldn't have any trouble with your insert or update processes.
Here's a thought:
Report currently has a column that links to the first page of items (page 14) with the retrieved row. Presumably you also have a Add New button on the report page that links to page 14 for a new row.
Define a Next button on page 14 that branches to the second page of items (page 16). Also define a Previous button on page 16 to return to page 14. But page 16 would be the only page with a Save button.
Now, if user clicks Add New, user will get a blank page 14. Once user enters the info and passes validation they click Next and will be sent to page 16 to enter the remaining info and Save.
If user clicks one of the column links, they will be brought to page 14 with the clicked row - they can change whatever info there and click Next, or just click Next, to get to page 16. After any changes are made, they click Save.
I'm assuming you've been thru the tutorials and realize that you'd really have two Save buttons defined for page 16 - one conditional on your primary key item having a value (existing record) and one conditional on it being null (new record) - check out the tutorials for more info, but this is how the application would know whether to run an insert process or an update process.
Hope this all makes sense and can help,
John

Signal to phone varies between 4G and 1X. Can that be improved without using antennae.

Signal strength varies from 4G to 1X, is there an adjustment in the phone to correct or is it necessary to buy xtra antennae.

Thank you for replying.
Signal varies in 61822 and 33917 zip codes. The incline plane emblem next
to battery icon never shows strength greater than just the tip of the
indicator except when I go to Verizon corporate store where they have a

No luck. I put in my password and restart the finder/cpu and these folders still remain visible. Anyone have any suggestions?

*Hi Tim. Looks like I do have the developer tools but for some reason maybe not that one tool. So I downloaded your file (thank you so much for allowing me to download it and for uploading it) and put it on my desktop as you suggested. Still no luck. The files still appear eventhough the commands went through.*
*See below (my terminal window afterwards)*

Does that have something to do with it?

Anybody seen this? before I go off on Yet AnotherMad Debian Bug Hunt?

Hey WD... Y'all's got a BUG... When I access the MyClod from my laptop running XP with FireFox, I get the thousands of "sess_*" files written to /tmp, and I get groups of messages of the form Jul 14 22:36:26 WDMyCloud REST_API[23951]: 192.168.1.101 ORION_LOG /var/www/rest-api/api/Auth/src/Auth/User/UserSecurity.php ISAUTHENTICATED [ERROR] Authentication failure for /api/2.1/rest/mediacrawler_status?_=1436938574613

Jul 14 22:36:26 WDMyCloud REST_API[23951]: 192.168.1.101 ORION_LOG /var/www/rest-api/api/Auth/src/Auth/User/UserSecurity.php ISAUTHENTICATED [ERROR] dbgvar0: Array\n(\n [_] => 1436938574613\n [RequestScope] => RequestScope Object\n (\n )\n\n)\n written to /var/log/user.log. But when I access it similarly from the desktop machine, also running XP with FireFox, I just get *one* of the "sess_*" whatever files written to /tmp, and just one set of messages of the form Jul 14 22:40:26 WDMyCloud REST_API[24325]: 192.168.1.100 OUTPUT DlnaServer\Controller\Database GET SUCCESS
Jul 14 22:40:29 WDMyCloud REST_API[23952]: 192.168.1.100 OUTPUT System\Configuration\Controller\FactoryRestore GET SUCCESS

Jul 14 22:40:51 WDMyCloud REST_API[23952]: 192.168.1.100 OUTPUT Alerts\Controller\Alerts GET SUCCESS written to /var/log/user.log. So the MyClod is playing nice with some computers and not others... My guess is this could be happening more than WD knows about and could be producing all manner of mysterious behavior, since not only does it only happen on some machines but it does *not* crash the MyClod - at least not right away. The main effect is to fill /tmp and /var/log with garbage so nothing can write to them, which will probably affect some things and not others... https://www.youtube.com/embed/2Gwnmb6P-3k
