Use Redirect Symbol to Zero File

2010-07-02T05:37:00.001-07:00

I have mentioned this topic in an earlier post - zero'ing logfiles with cat /dev/null > logfile. But there is another easy way to zero a logfile in Bourne or Korn shell. It probably works in Bash and Zsh, too. I have to check. Here is an example below.

Note: I used the gts to represent the "greater than" or redirect symbol because blogger complained about using that particular character. Update: themadengineer reminded me on the use of "greater than" html syntax. Thanks.

Bourne Shell at the command prompt

# > mylogfile

Korn Shell at the command prompt

# > mylogfile

Earlier post: Don't remove those log files - zero them

Run the Windows Explorer GUI

2010-06-28T05:44:00.000-07:00

Here are a few easy ways to invoke the Windows Explorer GUI, which displays certain parts of the directory/folder tree depending on given syntax. I also threw in a few other miscellaneous items.

1. Select Run
Then type "."
This action will invoke the C:\Documents and Settings\mysysad

2. Select Run
Then type ".."
This action will invoke a window that displays C:\Documents and Settings

3. Select Run
Then type "..."
This action will invoke a window that displays My Computer

Other misc Run exercises

Select Run
Type "explorer" - same as Type "My Documents"
Type "explorer c:"

Retrieve Information on LDAP User

2010-05-06T07:35:00.000-07:00

Here are a couple easy methods to get information from ldap for a particular user. Friend and I were talking about it yesterday because we had a typo in someone's login directory string (missing a character). He showed me a fancy one-liner but all I needed was a username, login directory, and its corresponding UID.

# ldaplist -l password username

# getent passwd username

# logins -x | grep username

The getent command is also handy to retrieve host and group information. It consults what databases are listed in the /etc/nsswitch.conf file.

# getent hosts hostname

# getent group 100

$HOME/.TTauthority not writable, auth entry not added

2010-04-27T05:13:00.000-07:00

After being absent from the work site for an extended period, I had a little problem with the dt session. I was being blocked a dt session (automatically logged me out--tried 3x). I observed Tooltalk/dt session errors on the screen.

But I also observed others logging into the same box without incident. Intuitively, I suspected something was wrong with my environment, so I logged in via a remote terminal. Once in the box, I reviewed the /var/adm/messages file and noticed /usr/dt/bin/ttsession errors were associated with my username. The messages file also contained this telling message - $HOME/.TTauthority not writable, auth entry not added.

Hmmm…ownership was not mine. I changed the ownership to yours truly and everything worked like a champ.

Microsoft Security Advisory --- F1 Key on Web

2010-03-03T03:31:00.000-08:00

A friend of mine from Japan emailed me this interesting article and thought I would share it.

Microsoft has issued a security advisory warning users NOT to press the F1 key when prompted by a website. This vulnerability could allow a hacker to hijack a computer. This vulnerability affects all versions of Internet Explorer on computers running Windows 2000 and Windows XP operating systems. More information can be found at

http://www.computerworld.com/s/article/9164038/Microsoft_Don_t_press_F1_key_in_Windows_XP

DO NOT press the F1 key if prompted by a website. Doing so could allow a hacker to hijack your computer!

Import and Enable the NFS Service

2010-02-27T22:15:00.000-08:00

Last week we had a little issue with mounting directories from a new Solaris 10 server. It was noted the nfs service was not running on it. We had to import and then enable the service. After that, we were able to mount the required directories from the server.

# svcs -a | grep nfs
# cd /var/svc/manifest/network
# svccfg -v import nfs/server.xml
# svcadm enable nfs/server

or

# svccfg -v import /var/svc/manifest/network/nfs/server.xml
# svcadm enable nfs/server

If you want to disable and delete a service, see below.

# svcadm disable network/nfs/server
# svccfg delete network/nfs/server

Issues With an Orphaned .attribute^ File

2009-11-23T07:07:00.000-08:00

We had intriguing problem related to a Unix-based directory. This directory was mapped to Windows via Citrix.

On the Windows side, the initial thought was that the folder was simply "hidden" via the attributes, which would be normal. However, the attributes for the folder didn't show the hidden option selected.

Recently, we performed an account migration activity on the Unix side. The culprit turn out to be an orphaned .attribute^ file on the Unix side. Apparently, this file's username and group was deleted prior to migration, and its state unexpectedly caused the directory's contents to be invisible to Windows-based viewers.

At any rate, we finally noticed the file with the ls -al command. The .attribute^ file was removed from the Unix side and viewing was back to normal on the Windows side.

ftpconfig - Setup Anonymous FTP

2009-10-23T07:10:00.000-07:00

To setup an anonymous FTP account, you might consider using the ftpconfig script. It seems to be a lot easier to setup an anon FTP account with Solaris 10 than it was for Solaris 8. The anon users log in and then they are given restricted access to a mini-root filesystem.

Here is the syntax.

# ftpconfig someftpdir
or
# ftpconfig -d someftpdir

If you have problems, you may have to check files in the /etc/ftpd directory. Hint: check the ftpaccess file

No Space Left on Device!

2009-09-18T08:26:00.000-07:00

About two weeks ago, my colleague and I had an issue with the /var partition on a seldom used Sun Blade 2500 workstation. Frankly speaking, I thought a simple fsck would suffice while in single user mode. Not quite. Anyway, we executed fsck on the partition and it "fixed" whatever errors reported. And while in single user mode, we wrote test files to the partition without incident. However, once we booted to init 3 run level, we still could not write to the /var partition, not even as root. That was a bit strange because df -k reported only 20% of the partition was used. hmmm...inode problem?? Then we looked through the logs and noticed a message about not having enough space on the device – in short, we ran out of inodes. Almost immediately, we suspected a problem with mail. We checked the mqueue directory and it contained almost a 1,000,000 small extraneous/useless messages from cron. We deleted most of them (after a few hours) and it resolved the issue. And yes, we got a handle on the cron that was generating those messages.

Troubleshooting Domain Issues with My SysAd Blog - Again

2009-07-10T00:18:00.000-07:00

Late last night (KST), I was reviewing my free MyBlogLog stats and noticed 8 visitors had stopped by the blog. Usually, by that time, mysysad would have had several hundred visits. I surfed over to the domain and verified it was down (this blog is hosted on the blogger.com platform and it is pointing to a custom domain). However, the blog was working with the old address, http://esofthub.blogspot.com

I pinged the old IP address - no answer. Then I pinged ghs.google.com, and it responded with a different IP address. I used that new address to update my A-Records with my domain registrar -- yahoo.

After 20-30 minutes of propagation, the mysysad.com domain was back online.

By the way, I just pinged the old address twice...no response. Update: 7 hours later - pinged again - no answer

Here is another post I wrote a few months ago about a similar issue...

142857 is an Interesting Number

2009-06-18T03:45:00.000-07:00

A couple of days ago a colleague sent me this interesting number, 142857, via email. I performed a Google search on the number and I was surprised to see so many returns - 190,000. It even has its own wiki page. For additional information, here is the wiki page for this cyclic number - 142857.

Below is the email.

Subject: Interesting Numbers

Roy,

I want to let you know a weird number which is 142857.

Why?

142857 X 1 = 142857
142857 X 2 = 285714
142857 X 3 = 428571
142857 X 4 = 571428
142857 X 5 = 714285
142857 X 6 = 857142

See, the answers show all same numbers with different position.

142857 X 7 = 999999

142 + 857 = 999
14 + 28 + 57 = 99

142857 X 142857 = 20408122449
20408 + 122449 = 142857

Interesting, huh?

Pipe Symbols are Missing from Some Posts

2009-05-30T08:52:00.000-07:00

You might have already noticed some of my theme formatting attempts appeared to have removed essential characters - in particular, the pipe symbols. I will try to go back and fix them when I get some time. I just want you to be aware of the inconvenience. Thanks Mr. Mendoza.

Gilbert Mendoza said...
Hey there. Just as an FYI, I believe your theme formatting has removed essential characters from some of your posts. For example, none of the pipe symbols separating each of the stringed commands are showing.

You're right Gilbert Mendoza. I just check a few posts and the "|" are missing. I guess changing between themes deleted them.

Field 'user_website' doesn't have a default value

2009-05-30T08:45:00.000-07:00

I received a few complaints about not being able to register an account on my phpbb forum. To confirm, I tried creating a test account.

Here were the results:

General Error

SQL ERROR [ mysql4 ]

Field 'user_website' doesn't have a default value [1364]

An SQL error occurred while fetching this page. Please contact the Board Administrator if this problem persists.

Please notify the board administrator or webmaster: some one @gmail.com

In my case, here was the fix. Of course, make sure you backup your database.

http://www.phpbb.com/kb/article/doesnt-have-a-default-value-errors/

I ran the commands via phpmyadmin. It works fine now.

Determine Java Runtime Environment Version

2009-04-25T04:26:00.000-07:00

A few days ago I was asked for a quick and easy way to determine what java runtime environment version was installed via the Unix command line. The requester was trying to determine possible compatibility issues for some recently purchased applications.

Bear in mind that you may have multiple JRE environments installed on your box so consider the PATH value -- meaning you might have to specify an absolute path. e.g. /usr/some_java_version/bin/java

Here is the Unix one-liner syntax using default path

% java -version
java version "1.x.x_xx)

...

By the way, it is the same syntax for Windows.

C:\Users\mysysad> java -version
java version "1.x.0_xx"
Java(TM) SE Runtime Environment (build 1.x.0_xx-xxx)
Java HotSpot(TM) Client VM (build xx.3-bxx, mixed mode, sharing)

Access a Tape Drive Device From a non-global Zone

2009-04-17T05:48:00.000-07:00

A couple days ago, I had a friend who wanted to know how to access a tape device from his Solaris 10 non-global zone.

Here is an example on how to add a device to an existing non-global zone. By the way, the commands below are ran from the global zone, and you will have to reboot the non-global zone.

# zoneadm list
mysysad-global

# zonecfg -z sysad
zonecfg:sysad> add device
zonecfg:sysad:device> set match=/dev/rmt/0n
zonecfg:sysad:device> end
zonecfg:sysad> verify
zonecfg:sysad> commit
zonecfg:sysad> exit

# zoneadm -z sysad reboot

After the reboot, you should be able to access the tape drive from the non-global zone.

Disable On-screen Keyboard on Startup

2009-03-24T06:00:00.000-07:00

I was playing around with a few of Vista's settings on my laptop. Unfortunately, one of those settings was the “On-Screen Keyboard.” I had the utility set to automatically start up each time I logged on; however, I did not want or need that convenience. After a few more logins, it got really annoying. It was time to unset the setting, but it took me awhile to rediscover the setting and uncheck it.

At any rate, here is the path to the setting via the control panel.

Control Panel=>Ease of Access Center=>Use the computer without a mouse or
keyboard=>On-screen keyboard (uncheck it and then Save)

Create Tarballs Greater Than 2GB

2009-02-04T01:07:00.000-08:00

I was tarring a Unix-based application today when I encountered tar's 2GB file size limit. Frankly speaking, I was a bit surprised the application was greater than 2GB because it was only few hundred megabytes a few years ago. Anyway, to get around this annoying limitation, I used the -E option, but it did not work. I realized that I was using a non-standard tar binary because of redefined paths -- per site policy. I specified the absolute path for the OS-based tar command and the tar activity worked fine.

Here is an example.

# /usr/bin/tar -cvfpE GreaterThan2GB.tar /opt/MYAPP

Identify Zone Processes via Global Zone

2009-01-29T06:24:00.000-08:00

I had a colleague of mine ask a question about how to identify processes that belong to a particular zone via the global zone because the global zone “sees” everything. Recently, I attended a class and it covered the "deltas" between Solaris 10 and Solaris 8 and this question surfaced there, too.

The quick answer is to use the "-Z" option, which is the uppercase form.

Here is an example from the global zone.

# /usr/bin/ps -efZ

Clean-up Dangling Dev Links - sp diff: name finddevice

2008-12-29T02:42:00.000-08:00

A couple weeks ago we encountered the "sp diff" message below on bootup. The message iterated about 15-20 times before continuing the final bootup sequence, which took at least twice as long as normal.

A colleague of mine recalled performing some multipathing activities a few days earlier and thought there might be some dangling dev links as a result.

To resolve the issue, the devfsadm command was executed in cleanup mode, -C.

sp diff: name finddevice, nargs 1, nret 1,sp 0xf05d35b8 osp 0xf05d35a8

...

# devfsadm -C -v

# init 6

Update: A message from a colleague who requested not to be named.

stmsboot -e will enable multipathing, the system needs to be rebooted in order for it to take effect.

When the system comes up, you will notice long device names in

/dev/dsk/. It may be coincidence but I noticed that the number of

multipathing devices listed match the number of sp diff lines that are

displayed.

Next, I did a stmsboot -d to disable multipathing and rebooted the

system. When the system came back online, I still saw the sp diff lines.

Lastly, I did the devfsadm -C -v and I saw it clean up the device links. I rebooted the system again and the sp diff lines were gone.

You would think that disabling multipathing should delete the links but

it doesn't.

Use Z-Shell for loop to Compact Argument List

2008-12-26T06:20:00.000-08:00

The other day I pinged a number of remote workstations to observe Round Trip Times (RTT) but forgot to eliminate a few series of contiguously numbered remotes that were known to be powered-off. Needless to say, the pinging effort was taking longer than it should have -- I promptly aborted the effort. Here is an example of a compact way of performing this common task using a Z-Shell for loop.

# zsh
# for blog in {1..5} {7..13} {15..22} {27..37}
for> ping -s mysysad$blog 1024 5

My SysAd Blog Temporarily Reverts to its Legacy Blogspot URL

2008-12-12T01:41:00.000-08:00

This evening I was checking my web statistics and noticed mysysad.com's traffic had plummeted. At first, I thought it had something to do with me adding a comment widget. You know the deal..."what did you change?" is a common sysad retort. But I quickly realize that was not the issue; it was a DNS issue. Here is a run of the events using the ubiquitous ping command. By the way, I have linked back to sysad several times because I have my very own unsolicited blog scraper.

copy running-config startup-config

2008-11-29T01:19:00.000-08:00

We had an issue a couple weeks ago when our power failed and so did the UPS. At first, everything seem to come back online as usual but later we noticed a "network issue." We didn't think much of it because operations were only somewhat degraded. After a few more tests, we noticed that our old style Cisco ATM switch had reverted to our legacy configuration. Apparently, the new running configuaration was not saved.

At any rate, here are the steps to save the running configuration for this particular IOS.

Hyperterminal or Telnet into switch

enable

Password goes here

config terminal

run your configuration commands here

and soforth

control+Z

enable

copy running-config startup-config (save permanently)

I was notified by the aforementioned My SysAd Blog commenter that another blogger was blatantly lifting content from "My SysAd Blog." I tried contacting the blogger but he or she was missing contact information on their blog. I left a comment on one of the offending posts regarding the infraction. Frankly speaking, I do not mind people using the tips or even copying them but do not copy without linking back. I appreciate the commenter who brought this to my attention. Thanks.

So far, I found 13 posts that were verbatim on the blog. I left a comment on this post, unable-to-switch-user.html, and I noticed it has since been deleted.

Strip a Prepended String From a Filename - Unix

2008-10-03T08:34:00.000-07:00

I had a process that was pre-pending by design its PID to a file name string. But unfortunately, it caused a few unexpected problems when this handling process inadvertently terminated. I had to rename the files without the defunct pre-pended PID string and then reprocess them (several thousand).

Here is what I used as a quick and dirty procedure.

# csh
# ls
prependPID_filename_etc1 prependPID_filename_etc2 prependPID_filename_etc3 prependPID_filename_etc4
# foreach filename (prependPID*)
? mv $filename `echo $filename | sed 's/prependPID_//'`
? end
# ls
filename_etc1 filename_etc2 filename_etc3 filename_etc4

# zsh
# ls
prependPID_filename_etc1 prependPID_filename_etc2 prependPID_filename_etc3 prependPID_filename_etc4
# for i in prependPID*
for> mv $i `echo $i | sed 's/prependPID_//'`
# ls

IrfanView - Comprehensive Graphic Viewer for Windows

2008-09-16T06:27:00.000-07:00

Yesterday, we were trying to run a couple practice exams via CD to prepare for a security based certification. However, our normal players didn't support the required file format. As usual, it was time to perform a quick Internet search. After awhile, I found this one viewer, IrfanView, which supported many different file formats - to include the one I was searching for. I downloaded the viewer and then later its plugins. It worked like a champ for my particular task. Anyways, here is some information about IrfanView and its supported file formats.

From Mr. Irfan Skiljan's website:

What is IrfanView?

IrfanView is a very fast, compact and innovative FREEWARE image viewer/converter for Windows 9x/ME/NT/2000/XP/2003/Vista.
