Waf Command In Ns3

Hi All,

I have perl script which I am trying to run on 1st Monday via cron job.
So I scheduled it as follows:

0 0 1-7 * * root ["$(date '+%a')" = "Mon"] && /usr/bin/perl script.pl

But then it didn't run so checked cron log and it seemed like its missing the command. so added a \ in front of %a and then it picked up the whole command as per cron log.

But still it didnt ran the script. I then change the script to just && echo "test">/tmp/test

Still nothing. if I run it as /usr/bin/perl script.pl it runs though

Thanks in advance.

Hello, good guys am new to linux and also the issue of NS2, I need to run by the NS2 + WiMAX + LTE, the more I'm in trouble, I did this step by step http://gotoanswer.stanford.edu/?q=in...imax+in+ns2.35, installed straight over at the time I enter / ns2-35 / tcl / wimax and run a script with the $ ns wimax-script.tcl command it returns an error as shown in the image below, if anyone can help me I would be very grateful, hugs.

I'm in the need of building a script to clean up my media library. I've been PVR'ing for years now and it's time to clean things up. For example, my TV Shows are saved as such:

/media/storage/Show Name/Season 1/Show Name - S01E01 - Episode Name.mp4

Over the years I've created a bunch of subdirectories further than that and I want to go through and clean those out. For example, the following directory might exist:

/media/storage/Show Name/Season 1/subtitles

If I use the find command, with -type d and -maxdepth 4, I have discovered that the subdirectory I want to delete is in the 4th level. There should be nothing valid in the 4th level and okay to delete.

I don't really know where to start. I tried using the find command with -mindepth 4 but that doesn't seem to work as I would expect. Basically, I want to scan through the library, then I want to test to make sure that the directory isn't "Season XX" and if it is a subdirectory within Season X then I would like to delete that subdirectory.

Any ideas how I can accomplish this?

FYI: I'm using Korrora 21 with BASH.

I am using a shell script named by test.sh, for example containing
Code:

address="$PWD"
echo "$address"

.
If I put it in folder temp1, and run test.sh, then it will give me the address of the current directory. But if I am now in folder temp2, and I want to run test.sh, I always need to copy test.sh to folder temp2, and then run it. Is there a way that I can run test.sh without copying it? I am not root user.

Hy All,

I have two nodes running RHEL 6.4 which are in cluster. I have clustered httpd service. Now I have certain application suppose X which reside in SAN partition. Now my job is to only automate this script to run by analyzing httpd status. I have successfully created the script apptrigger.sh whose content is given below,

-bash-4.1$ cat apptrigger.sh
a=0
b=0
c=0
d=0
a="service httpd status"
b=`eval $a`
##### CHECKING WHETHER HTTPD SERVICE IS RUNNING OR NOT #####
if [ "$b" != "httpd is stopped" ]; then
c="bash /switchapp/switch/ezlinkenterprise/bin/ezlink-cluster.sh status"
d=`eval $c`
##### CHECKING WHETHER EZ IS RUNNING OR NOT #####
if [ "$d" != "EzTaskMgr is Running" ]; then
ezstart
fi
fi

I have created this script in say test user. Now when I put this script to automate or run every minute through test user and defined its value in crontab -e of test user whose content is as shown below
$crontab -l
* * * * * /bin/bash /home/test/apptrigger.sh

but this script is running as root user so I cannot get the o/p
I think some environment variable need to be set. Anyone can guide me with this step? Thanks for your views and suggestion.

Hi All,
We have some shell scripts which will send emails about backup, alerts etc using mail command. Example.
Code:

echo "Test Mail" | mail -s "Test" me@mydomain.com

I guess the above command just connect port number 25 of our mail server even if we do not define any port number. Now I would like add smtp port number as 587 in all of the bash scripts. I googled for this but could not get whatever I am expecting. So expecting your kind reply to define smtp port number as 587 in all of the bash scripts.

Thanks in advance.

Hi

this is true:

#!/bin/bash

if [ -a /tmp/jboss7_pid.txt ]; then
echo "it exist!"


but what if I also need to check 2 files in /tmp? lets say jboss4_pid.txt. I tried this but didnt worked out

if [ -a /tmp/jboss7_pid.txt -a /tmp/jboss4_pid.tx ]; then
echo "it exist!"

Hi All,
We have qmail server running on RHEL6.5. We have already made sure that our server is not acting as an open relay with the help of http://mxtoolbox.com/diagnostic.aspx.
But still anyone can telnet to our domain and send fake emails to anybody@ourdomain.com. For example Code:

telnet mail.ourdomain.com 25
helo mail.ourdomain.com
mail from: unknown@anyname.com
rcpt to: anyemailid@ourdomain.com
data
from: "Any Unknow name" <unknown@anyname.com>
to: "Some user Name" <anyemailid@ourdomain.com>
subject: Testing MTA with telnet

Hi,
This way anybody can fool us.

Regards,

.
quit

So can anybody pls help me to prevent this. I meant to say, we should not block port 25, instead it should verify whether or not "from email id" is exist in our domain, if it is exist then it should ask for the password also or if it is not exist then also it should not take us to next step. Because as per above example anybody can fool us as the mail is coming from outside but it is just from our domain to our domain without any authentication!!!
Expecting your kind help to block sending mails in this way.
