Remote execution of command to find available space logging in ftp mode.

unixuser · 01-31-2008, 01:33 PM

i have the below program to connect to remote unix box and to find the space on the other machine being at the ftp prompt.

i dont want to use ssh, etc apart from this approach. can any1 help me out in this regard?
`ls -ld /app | awk '{ print $5; }' > percent.txt`
the above command is working fine but how to find the exact space utilized in that particular directory? Coz i cannot use df -k command at ftp prompt. if i use ! mark !df -k it gives the current box space and not the space of the box where i am connected to with ftp

If you use the utility 'expect', it will make your life WAY easier. That utility should come with a script called autoexpect. Once you have it, just run the 'autoexpect' command and issue the commands that you wish to use. Once that is done, type 'exit'. That will drop you out of the script creation and write the file... it defaults to script.exp. Once that is done, edit the file to accept positional variables.

Here's an example:

Code:

set force_conservative 0  ;# set to 1 to force conservative mode even if
                          ;# script wasn't run conservatively originally
if {$force_conservative} {
        set send_slow {1 .1}
        proc send {ignore arg} {
                sleep .1
                exp_send -s -- $arg
        }
}


set timeout -1
set host [lindex $argv 0]
set ip [lindex $argv 1]
spawn telnet $host
match_max 100000
expect -exact "Username: "
send -- "user\r"
expect -exact "Password: "
send -- "pass\r"
expect -exact "HR>"
send -- "en\r"
expect -exact "Password: "
send -- "pass\r"
expect -exact "HR#"
send -- "ping\r"
expect -exact "Protocol \[ip\]: "
send -- "\r"
expect -exact "Target IP address: "
send -- "$ip\r"
expect -exact "Repeat count \[5\]: "
send -- "10\r"
expect -exact "Datagram size \[100\]: "
send -- "36\r"
expect -exact "Timeout in seconds \[2\]: "
send -- "1\r"
expect -exact "Extended commands \[n\]: "
send -- "\r"
expect -exact "Sweep range of sizes \[n\]: "
send -- "\r"
expect -exact "HR#"
send -- "q\r"
expect eof

In this example we have created a script to login to a cisco router and ping hosts. If you create a file with a list of ip addresses, each on their seperate lines, then use something like this:

Code:

for ip in `cat file`
    do
          /path/to/script.exp $1
          more code...
    done

Although now that i read your post completely, it seems as though that what i have suggested wont work. Why do you want to use FTP to get the size of the directory?

y we want to log in FTP mode is that. this script runs on production unix boxes. and we dont have permissions to login as anonymous user etc.... so found this approach to find the disk space (dont know this works r not). all the unix boxes are having weblogic instanes running. as the weblogic logs pile up, the disk space minimizes to ZERO, which results in PROD weblogic instance to go down. to avoid that we want to define a crontab job which runs every one hr on the prod boxes to check the disk space. and that too the script should run only from one of the PROD box and log into other PROD boxes and if the disk space is more than 90% should send an email to the concerned people

Any update on my problem please do reply to this thread.
