Shell Programming and Scripting

Sadly I have problems with my edit function so here an addition to make the code work. I forgot to end the line with:

Code:

....ctor port="\([^"]*\)" .*/\1/p' ; done < server.list

thanks zaxxon for this idea..

$> cat server.list
192.168.1.10

but one error

Code:

[me@linux ~]$ while read S; do ssh -n -o "ConnectTimeout=3" -o "BatchMode yes" $S "cat /tomcat6/apache-tomcat-6.0.26/conf/server.xml" | sed -n 's/.*Connector port="\([^"]*\)" .*/\1/p'  ; done < server.list
Permission denied (publickey,gssapi-with-mic,password).

can i tell one another idea..

gives the output as

Code:

grep "`date +"%b %d"`"

will give the date started..

but i don't know how to code exactly this..

zaxxon ,

In this script i have to ssh each time the script is running. am i right ?

here actually one problem is there.

i am sorry that i did't give the complete spec.

The thing is:

1. i will create a shell script to get port number of tomcat , running or not , some other server info..etc and append the output to a file_details

2. I will put this script in each of our servers (say 10 servers)

3. And i will get the info from file_details whenever i need.

The while loop will cycle through the lines of the input file, where on each line is the name or IP-address of a single host to be inspected. So 10 lines will be 10 ssh connects, one to each host.

If you deploy that script on each host, you'll have to ssh to each one though to get the information. There are different ways to achieve what you want - you could also run that script via cron on each box and have them connect to your central box delivering the info to it in intervals or once a day, whatever.

But to have passwordless communication with ssh between the hosts and your central collection box, you would have to create passwordless ssh-keys and exchange the public ssh keys to your needs.

thanks zaxxon for your fast reply..

But what about this..

Like this?

Code:

awk '/^INFO: Starting/ {sub(/\/1.1/,"",$4); a=$1 FS $2 FS $3 FS $4; split($NF,arr,"-"); b=arr[2]; getline; sub(/,$/,"",$2); print $1,$2,a,b}' infile
Jul 21 INFO: Starting Coyote HTTP 8080
Jul 21 INFO: Starting Coyote HTTP 8080
Jul 21 INFO: Starting Coyote HTTP 8080

Or without a split, just deleting .*-:

Code:

awk '/^INFO: Starting/ {sub(/\/1.1/,"",$4); a=$1 FS $2 FS $3 FS $4; sub(/.*-/,"",$NF); b=$NF; getline; sub(/,$/,"",$2); print $1,$2,a,b}' infile

Thanks a lot.. for this Great work..

Thanks...


i made it like this..

Code:

cat `echo $CATALINA_HOME/logs/catalina.out` | grep -B10 "INFO: Server startup in" | awk '/^INFO: Starting/ {sub(/\/1.1/,"",$4); a=$1 FS $2 FS $3 FS $4; split($NF,arr,"-"); b=arr[2]; getline; sub(/,$/,"",$2); print $1,$2,a,b}' | tail -1 | awk '{print $7}' | uniq

output:
8080

got one more.. which gives all ports for tomcat , server listens..

Code:

netstat -anp | grep `ps -ef | grep catalina | grep -v "grep catalina" | grep -v "catalina.out" | awk '{print $2}' | head -1`  | grep LISTEN | awk '{print $4}'  | awk -F: '{print $NF}'
