Does anybody know what is wrong here. I am running centOS

Code:

the anticrash gives me this.

#!/bin/sh

while true
do
  rm banme.tmp
  :> banme.txt
  /usr/sbin/tcpdump -p -c 100 -n -i eth0 "dst host 66.197.12 6.19 and udp port 7777" >banme.tmp 
  grep "length 0" banme.tmp | cut -f 3 -d " " | cut -f 1-4 -d "." >> banme.txt
  if [ `grep -c . banme.txt` -gt 0 ]
  then
    ip=`head -1 banme.txt`
    if [ `grep -c ${ip} /etc/sysconfig/iptables` -eq 0 ]
    then
      dat=`date`
      echo "${dat} adding ${ip} to iptables" >> banme.log
      /sbin/iptables -A INPUT -s ${ip} -j DROP      
      /sbin/iptables-save > /etc/sysconfig/iptables
    else
      echo "${ip} is already in iptables" 
    fi   //LINE 20<<
  fi
  sleep 0
done

[root@inerdtech control]# sh ./anticrash.sh
: command not founde 2:
./anticrash.sh: line 20: syntax error near unexpected token `fi'
'/anticrash.sh: line 20: ` fi

Comment the red part of of your fi command :

Code:

    else
      echo "${ip} is already in iptables" 
    fi   # //LINE 20<<

the comment doesnt exist in the real script it was simply used to show what line it was any ideas

The script seems to be proper, check the file with vi, do you see a ^M at the end of a lines?

Hi
I used # in line 20, thus:

Code:

    fi   # //LINE 20<<

That works!

[root@inerdtech control]# sh ./anticrash.sh
: command not founde 2:
./anticrash.sh: line 20: syntax error near unexpected token `fi'
'/anticrash.sh: line 20: ` fi #//LINE20

these are what i get if i use the #//line20 and also no i donot have ^M any other suggestions?

Try to execute your script with the command :
Code:
```
/bin/sh ./anticrash.sh
```
Execute your script with the debug option, and show us the output:
Code:
```
which sh
sh -vx ./anticrash.sh
```
