DHCP request at system startup via shell script

Hi all,
I administer about 120 macs and a couple of weeks ago the network admin changed the ipv4 network and the dhcp-leases, -ranges.
My macs do not get an ip address when they start up.
It takes about one minute until the request is succeeded.
I am about to write a shell script that starts a dhcp request over the network.
I want to use the same command that the network system pref (Renew DHCP Lease) uses.
I read the bootpd, xinetd, lookupd manual but I am not sure wich one is the correct deamon to use.
Someone can help?
Thanks in advance
Cheers Thorsten

Seen the ipconfig yet?
http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/ipconfig .8.html
Two ways to renew a lease in Terminal, adjust your enNUMBER accordingly...
sudo ipconfig set en0 BOOTP;sudo ipconfig set en0 DHCP
sudo ifconfig en1 down;sudo ifconfig en1 up

Launchd won't send email via shell script

I'm trying to send an email via shell script. e.g. my shell script is something like this:
#!/bin/sh
echo testing | mail -s 'this is a test' [email protected]
My launchdaemon runs the script: /usr/local/scripts/testscript.sh
I know the script is working, because I added some debugging (I added a line: echo is this working and sure enough, "is this working" is showing up in the console) but the email part kicks off an error message about 30 seconds later: Stray process with PGID equal to this dead job: PID ### PPID 1 sendmail
The script works when I run it with a cron job. But why wouldn't it work as a launchd item? And why is it I'm only having problems with the email segment of my scripts? I've tried other scripts and they all seem to work fine.

There are no errors reported. I'm looking in /var/log/mail.log.

BI Admin Tool - Setting connection pool via shell script - Is it possible?

Hi,
Here's the problem I am trying to solve.
I am using a J2EE application that uses OBIEE for reporting.
The *.rpd file is installed at a particular location when our J2EE product is installed.
I then copy the *.rpd file to the BI home on a different server using a shell script.
The shell script that deploys the *.rpd file does the following:
1. Shuts down BI processes that are running
2. Deletes the old *.rpd file
3. Copies the new *.rpd file
4. Starts all BI processes
I am happy with the way we have automated this process, but would like to take it one step further.
The *.rpd file does not have the connection pool hard-coded in it. And we want to keep it that way.
What we would like to do is - pass the connection pool parameters to the shell script (that is used for *.rpd's deployment) and have it automatically update the *.rpd file. Is it possible to do this at all? How do we go about accomplishing this?
Or in other words - Is there a way to update the connection pools WITHOUT hard-coding it in the *.rpd file or WITHOUT using the BI Administration Tool.
Currently, we manually update the connection pools in the Physical Layer using the Oracle BI Administration Tool.
The version of BI Administration Tool being used is 10.1.3.3.1 installed on a Microsoft Windows XP Professional SP2 machine. The BI Server itself is running on an Oracle Enterprise Linux 4.0 box.
Do let me know if you need more information that would help answer this question.
Thank you.

Thank you - fiston and Gagan.
I am going with fiston's solution - since it is easier to implement. I am on the QA team and the automated deployment is to lessen QA's deployment time.
While one of our developer's said that she prefer's Gagan's solution - it would be over-kill to make changes to the application's schema for the said purpose.
I will further make another post as to whether or not the automated deployment worked for us.

Mounting Samba (Windows) drive via shell script

This question is for the seasoned Unix geeks among us.
I have a `zsh' script (read bash/ksh on steriods) at work that prepares my build environment prior to running an Ant script (read `make' for Java). The Ant script actually looks for code that is on a shared directory, usually mounted over Samba (cifs). If I forget to manually mount this drive (Finder > Go > Connect to Server...) then the script will bomb.
Now, I have tried various attempts at using the `mount_*' commands, but can't seem to get them to actually mount a drive. I'm fairly certain that `mount_smbfs' is what I want to use, but calling it doesn't seem to work as the `man' file suggests. Naturally, I want to add this mounting call to my environment setup prior to calling the build script.
Any tips from a seasoned Unix hack out there? Thanks!
Tim

There is a unix forum here which would be a better place for this question, but I believe the problem is you haven't created a mount point in the Volumes folder which would then be the path argument.
Here is the examples from the mount_afp
EXAMPLES
The following example illustrates how to mount the afp volume server.com-
pany.com/volumename/ at the mount point /Volumes/mntpnt:
mkdir /Volumes/mntpnt
mount_afp afp://username:[email protected]/volumename/ /Volumes/mntpnt
This example shows the proper url to use to mount the volume guestVolume
from the afp server myserver as guest:
mkdir /Volumes/guest
mount_afp "afp://;AUTH=No%20User%20Authent@myserver/guestVolume" /Volumes/guest
This example shows the proper url to use to mount the volume myVolume
from the afp server myserver using Kerberos authentication:
mkdir /Volumes/myVolume
mount_afp "afp://;AUTH=Client%20Krb%20v2@myserver/myVolume" /Volumes/myVolume

Run a sudo command on system startup via Applescript?

Hey, I'm trying to hide the Spotlight icon on my menu bar using the sudo command shown here:
http://osxdaily.com/2011/12/12/hide-spotlight-menu-icon-mac-os-x-lion/
It works fine, but when I reboot my Mac (I tend to turn it off at night since it has a habit of waking from sleep by itself) the icon has re-appeared, and I need to run the command again.
I'd ideally like to write an Applescript to run on launch to execute the two commands (which also requires entering my password), but I've not been successful, I get various errors talking about authentication and such.
Is there an easier way to get this icon permanently hidden? I use Alfred, so while I make use of the Spotlight index, I never touch the magnifying glass icon, and I like to keep a clean menu bar!

You don't need applescript. What you need to create is a LaunchAgent. Lingon (available through the App Store) can help you write it. But, there are other sources that can show you how to write the raw file and put it in the LaunchAgents folder, like here: http://www.devdaily.com/mac-os-x/launchd-examples-launchd-plist-file-examples-ma c

Access System Resources using Java Applet via Java Script

Hello
I can access my Applet public methods (and this methods access system resources) via Java Script if I do the following: System.setSecurityManager(null);However, I'm making this post because I don't like this solution.
Supposedly, setting the SM to null is like making the Applet (which is signed and was accepted by the user via a prompt from the browser) behave like a normal Java program that has no restrictions. (http://java.sun.com/docs/books/tutorial/essential/environment/security.html, second paragraph)
However, this feels like a workaround of something that is supposed to be there (the SM).
Also, if I make the methods invocation from inside the applet (using swing buttons and textboxes for example) I can use the standard SM without no problems.
From my readings, the problem regarding Java Script invocation, comes from the fact that the Java Script is not a secure (not signed) source (because you can invoke public methods the way you wish from it i guess) on the contrary to the applet methods invoked by the buttons.
Possible solutions I found in the web range from using the public static Object doPrivileged(PrivilegedAction action) method or imaginative things like creating new threads on the public method that call the private methods that access the system resources (supposedly because the new thread runs under the safe environment of the applet)
I almost got a glimpse of hope with this post http://forums.sun.com/thread.jspa?threadID=5325271&tstart=0
However, none of these solutions worked, the only results were with the setResourceManager(null)So, any one can contribute with a solution for this? Should I keep trying to find a solution other then the one I already have?
Regards
Cad

1. yes
2. yes
Note for 2. the converter will run the applet with SUN jre for sure if the user has IE.
IE will use the ActiveX technology to run the applet (as with Macromedia Flash).
For Netscape I am not sure, but I would think Netsape will use the plug in provided by
SUN.
Note for SUN jre 1.3. If this applet is to be used within a company that uses a proxy with
ntlm authentication the 1.3 applet cannot connect (to the Internet) through this proxy since
ntlm athentication is supported since j2re1.4.2_03. There is one version before that but
that one will pop up a window asking for the user's domain account and password wich
is both lame and crappy.
As for the IE settings, IE has a default setting that askes users the "do you trust"
queston for AciveX controls within the Internet securety zone (tools -> internet options
-> security).
Sincy anybody can make ActiveX controls (allso sign them) a user that has a problem
to find the "no" button will sooner or later install a malicuous ActiveX control (spy ware
or a virus).
If this user's desktop is within your company's network it will cause serious harm.
This is why most company's disable this by changing the default internet expolorer
settings. Since I assume you are writhing this applet to be used by a company I allso
assumed that company has someone to maintain the desktops. In that case I
assume that person would want to control the security within the SUN jre instead of
letting the user deside what to trust and what not.

Using launchctl command within a shell script

I have successfully installed two daemons, and I would like to be able to disable and enable them via shell scripts, called by the daemons themselves. Here is my first shell script:
#!/bin/sh
# Testing for presence of a CODEBOY file
if [ -e "/Volumes/CODEBOY/Change.txt" ]
then
osascript '/Users/praxisii/Library/Scripts/MacScript.scpt'
launchctl unload -w '/Users/praxisii/Library/LaunchDaemons/WaitDaemon.plist'
launchctl load -w '/Users/praxisii/Library/LaunchDaemons/RunDaemon.plist'
fi
The daemon works just fine, running the background, calling this script, which is waiting for me to plug in my flash drive (entitled CODEBOY). When the flash is plugged in, the applescript is called, and the first launchctl command is executed, which disables the WaitDaemon. As advertised, the .plist file is re-written with the Disabled key set to true. The next line (which is supposed to enable the RunDaemon) is never executed.
Similarly, if the launchctl line is placed before the osascript line, the applescript is never called. It is as if the shell ignores everything after a single launchctl command, which it will execute.
Any ideas or comments?

Gary:
Thank you for the link to the TN2083. Long, but very informative.
I appreciate all the other comments on this thread. I am an amateur AppleScript/UNIX scripter, and any opportunity to learn more is much appreciated.
I have completely re-worked my original launchd agent system for automatic processing of a file on a flash drive. Here is the .plist file that I now use:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>RunOSAscript</string>
<key>LowPriorityIO</key>
<true/>
<key>Program</key>
<string>/usr/bin/osascript</string>
<key>ProgramArguments</key>
<array>
<string>osascript</string>
<string>/Users/casdvm/Desktop/AutoFlash.scpt</string>
</array>
<key>RunAtLoad</key>
<false/>
<key>ServiceDescription</key>
<string>Runs Applescript directly</string>
<key>StandardOutPath</key>
<string>/Users/casdvm/Desktop/AutoFlashLog.txt</string>
<key>StartInterval</key>
<integer>25</integer>
</dict>
</plist>
The AutoFlash.scpt is an Applescript that simply uses the Finder to check for the presence of a specific file on the flash drive. If it is there, and a certain script property has a value of 2, then it runs the AppleScript that processes the desired file on the flash drive. Once that is done, the script property is set to 0 (to prevent the processing from happening over and over again.). Once the flash drive is removed, the script property is set back to 2 in anticipation of the next time the flash drive is plugged in.
It is much simpler than the two agents I was messing with beforehand. I did indeed discover that this .plist needs to be saved in the LaunchAgents folder of my user Library (thanks again for pointing that out, Gary).
The only problem that I have involves the continuous calling of the Applescript from the launchd agent. As you can see from my .plist file, that AppleScript is called every 25 seconds. I tried setting it up using the OnDemand key, but I kept receiving a re-spooling error of some sort (I don't recall exactly; my notes are sketchy on that phase of testing), so I just decided to have it go every 25 seconds. It really doesn't matter, since I can leave the flash drive plugged in all day anyway, and it only processes the desired file once.
Thanks again for all the commentary and discussion; I am grateful for the assistance.

How does one run a shell script at system startup?

Hi,
I am trying to unmount my Boot Camp hard drive on my MacBook Pro. Now what I could do is create an automator action, save it as an application and then put it into my user´s login items. I am wondering though - shouldnt it be possible to run a simple shell script command like +diskutil unmount /Volumes/"Boot Camp"+ sometime during the startup process?
Or to put it another way - is there an easy way to do this or do i have to create an manage a daemon through launchd ?
Your help is very much appreciated.

sorry I forgot to mention that there is a bug in Lingon which creates a plist incorrectly if you enter your script explicitly on line 2. At least I haven't been able to make it work. A workaround I always use it the following.
Save your script as a *plain text* file from your favorite text editor. change the extension to .sh and make the file unix executable. Now, when you ccreate a launch daemon using Lingon, enter the path to that file instead of the script itself.
This always works for me.
Good luck!

What actions should I take after seeing this script running @ startup today? "ARDAgent\" to do shell script \"say quack\"'"

STEPS TAKEN:
Logged into Mac for first time today.
Noticed a new individual file in Directory Library ".a.text". (Settings disply hidden system file/folders)
File contained only the text "--purge".
Meta data on file directed source to bash process run @ startup.
Attached History command output.
Disabled ARD for now.
SETTINGS:
All Sharing was Off.
Firewall was set to Block All Incoming Connections.
Home network with no other active users at time.
Upgraded to Mavs 10.9.2 last night.
Do not use any file sharing or remote access into Mac.
The SSH host attempts were my old Amazon EC2 instances.
Appears to start bitcoin app and few databases.
Worth noting I've been having tons of various issues last few months.
Thanks.

I'm extremely unclear on exactly what's happening. You mention something about a script running at startup in your subject, but then never mention that again. What's going on there? Where are you finding that script?
That script would suggest someone playing a joke on you, by making your computer say "quack" every time you start up. That's not indicative of malware.
On the other hand, a hidden file as you describe is a common malware trick, though I'm not sure why it would only contain "--purge" - that isn't a complete command, as far as I know, and the purge command isn't likely to be used for malicious purposes anyway.
Still, you do have some indication that you're using Bitcoin-related apps, and there has been some Bitcoin malware that has appeared recently. See:
New CoinThief malware discovered
Note that the post on MacRumors that you refer to in your second post is almost six years old, and references a vulnerability that was closed later in 2008. It's completely irrelevant to any modern system.

Shell Script for Startup and Shutdown the database

Hi,
i want Shell Script for Startup and Shutdown the database in Solaries.
could any one can hep me where i can get this script. or send to me to [email protected]
Thanks & Regards,
Gangi reddy

SHUTDOWN
SHUTDOWN ABORT]
Shuts down a currently running Oracle instance, optionally closing and dismounting a database.
Terms
Refer to the following list for a description of each term or clause:
ABORT
Proceeds with the fastest possible shutdown of the database without waiting for calls to complete or users to disconnect.
Uncommitted transactions are not rolled back. Client SQL statements currently being processed are terminated. All users currently connected to the database are implicitly disconnected and the next database startup will require instance recovery.
You must use this option if a background process terminates abnormally.
IMMEDIATE
Does not wait for current calls to complete or users to disconnect from the database.
Further connects are prohibited. The database is closed and dismounted. The instance is shutdown and no instance recovery is required on the next database startup.
NORMAL
NORMAL is the default option which waits for users to disconnect from the database.
Further connects are prohibited. The database is closed and dismounted. The instance is shutdown and no instance recovery is required on the next database startup.
TRANSACTIONAL [LOCAL]
Performs a planned shutdown of an instance while allowing active transactions to complete first. It prevents clients from losing work without requiring all users to log off.
No client can start a new transaction on this instance. Attempting to start a new transaction results in disconnection. After completion of all transactions, any client still connected to the instance is disconnected. Now the instance shuts down just as it would if a SHUTDOWN IMMEDIATE statement was submitted. The next startup of the database will not require any instance recovery procedures.
The LOCAL mode specifies a transactional shutdown on the local instance only, so that it only waits on local transactions to complete, not all transactions. This is useful, for example, for scheduled outage maintenance.
Usage
SHUTDOWN with no arguments is equivalent to SHUTDOWN NORMAL.
You must be connected to a database as SYSOPER, or SYSDBA. You cannot connect via a multi-threaded server. For more information about connecting to a database, see the CONNECT command earlier in this chapter.

Sqlplus in Shell Script with startup pfile

I have the following entry in my Korn shell script:
${ORACLE_HOME}/bin/sqlplus -s /nolog << EOSQL >> ${PR_LOG}
connect / as sysdba
whenever sqlerror exit sql.sqlcode;
startup pfile "/u01/app/oracle/admin/${ORA_SID}/pfile/spfile${ORA_SID}.ora";
EOSQL
When I execute the script I get the following errors:
LRM-00123: invalid character 0 found in the input file
ORA-01078: failure in processing system parameters
I've isolated the problem to the 4th line. When I change it to simply "startup", everything works. I did try changing the quotes to ` and ', but those didn't work. I even explicitly listed the ORA_SID, and I'm still getting the same error messages.
Any ideas how I can resolve my problem with the 4th line? All help is appreciated.

and yes I want to start the database with the spfile.
If I just use "startup", everything is fine; and I can start the database with the spfile, because I have a symbolic link under $ORACLE_HOME/dbs to point to my actual spfile location - /u01/app/oracle/admin/salsa/pfile/So... what's the problem ? Just use "startup", if I'm not wrong you'd use the same spfile.
To use that syntax you should create a file with a line like this
spfile=<path of spfile>
and start as
startup pfile='<path of that file>'

How to detect a system crash (shell script)

what is the easiest way to find out if the system has previously crashed or been powered off without a clean shutdown?
i am looking for a way to be used in a unix shell script. is there e.g. a specific text i can look for in a specific logfile?
a panic.log might not be enough because in case of power failure the system will not have time to write to that logfile.
any help is greatly appreciated.

The shutdown codes are not documented anywhere that I know of. I've seen these mentioned, but I don't know whether they're all accurate.
-128: Battery or UPS dead (?)
-62: PMU did not detect heartbeat (PPC Xserve)
-60: Thermal (?)
   0: Low power
   3: Forced shutdown
   5: User requested restart or shutdown
