Ssh to validate multiple remote hosts connection validation.
Dear Folks,


I am trying to read a config file contains ip and port numbers.
i want to read each line of the config file and check ssh connection is happening or not.

Kindly guide.

Config file:
Code:
abc@1.2.342        22
abc@1.2.343        22
abc@1.2.344        22
abc@1.2.345        22
abc@1.2.3.116       22
abc@1.2.3.117       22
abc@1.2.3.118       22
abc@1.2.3.119       22
abc@1.2.342        2222
abc@1.2.343        2222
abc@1.2.344        2222
abc@1.2.345        2222
abc@1.2.3.116       2222
abc@1.2.3.117       2222
abc@1.2.3.118       2222
abc@1.2.3.119       2222

Code:
#!/bin/sh
while read -r lines || [[ -n $lines ]] ;
do
        hosts=`echo $lines | awk '{print $1}'`
        port=`echo $lines | awk '{print $2}'`
        ssh -q -o "BatchMode=yes" -p $port $hosts "echo 2>&1"
        [ $? -eq 0 ] && echo "Connected to ${hosts} for port ${port}" || echo "Connection refused to ${hosts} for port ${port}, Please check"
done < /home/ssh_configfile

Kindly help, it is checking only for one ip, rest is not passing as an argument.
Regards,
sadique

fs_whereis

FS_WHEREIS(1)						       AFS Command Reference						     FS_WHEREIS(1)

NAME

       fs_whereis - Reports each file server housing a file or directory

SYNOPSIS

       fs whereis [-path <dir/file path>+] [-help]

       fs whe [-p <dir/file path>+] [-h]

DESCRIPTION

       The fs whereis command returns the name of each file server machine that houses the volume containing each directory or file named by the
       -path argument.

OPTIONS

       -path <dir/file path>+
	   Names each AFS file or directory for which to return the host file server machine. Partial pathnames are interpreted relative to the
	   current working directory, which is also the default value if this argument is omitted.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output includes a line for each specified directory or file. It names the file server machine on which the volume that houses the
       specified directory or file resides. A list of multiple machines indicates that the directory or file is in a replicated volume.

       Machine names usually have a suffix indicating their cell membership. If the cell is not clear, use the fs whichcell command to display the
       cell in which the directory or file resides. To display the cell membership of the local machine, use the fs wscell command.

EXAMPLES

       The following example indicates that volume housing the directory /afs/abc.com resides is replicated on both "fs1.abc.com" and
       "fs3.abc.com":

	  % fs whereis -path /afs/abc.com
	  File /afs/abc.com is on hosts fs1.abc.com fs3.abc.com
