sshpass stops parsing piped input after 70 lines

Question

I made a bash script to automatically update a object-group on a Cisco ASA with office365 IPs via SSH.

I'm getting the IPs from MS, building the right command-syntax for the ASA, and writing all commands in a file (right now 90 lines, but as this is dynamic it can grow or shrink). Then I want to push the commands in the file to the ASA with:

cat outfile.txt | sshpass -p "Password" ssh -t -oStrictHostKeyChecking=no [email protected]

but sshpass stops sending commands after line 70. so outfile.txt has 90 something lines but no matter on which host I try to "deploy" the commands, it just send's the first 70 lines. After that i just get a

Connection to 1.1.1.1 closed by remote host.

On the firewall I see a TCP reset from the server, but as I said it doesn't matter on which host (tried different Firewalls, Routers and other servers) I try it won't send more than the first 70 lines.

Anyone got a solution for my problem or another way to achieve my problem?

Thanks

Answer 1

Try this, maybe it's not pretty but should work. the last message from server can be also "Connection closed by remote host" but all config should be added properly already.

#!/bin/bash

where="<path to your outfile.txt>";
len=`cat $where | wc -l`;
config=`for (( c=1; c<=$len; c++ )) do line=\`sed -n "$c""p" $where\`; echo $line; done`;

sshpass -p "Password" ssh -t -oStrictHostKeyChecking=no [email protected] $config

Please consider also to use ssh key instead sshpass.
