Bash - here document on RHEL 6.8 and 6.9 servers aren't working
H Forum,
I was thankful in getting help from this post that allowed me to connect to multiple severs at once using here documents to gather data into variables. But I've discovered that the same bash command that works on my RHEL 7 servers do not work on RHEL 6? What's strange about my problem is that I'm not getting an error either. The problem is that the variables return empty when I try the following code on RHEL 6.8 or 6.9 servers we manage:
I've thought of adding in the ability to determine if my server is RHEL 6 or 7 using code like the following:
python -mplatform | grep -qi red &&
but even if I could determine RHEL version I'm still not sure why my RHEL 6 servers do not return variable data back. I've tested this above code connecting to just one server to try and triage the issue. No errors are returned. the variable fields are just empty. Whereas on my RHEL 7 servers I return back variables with no issue. Could it be that how I use Here Documents just doesn't work with RHEL 6 servers? has anyone seen this before?
I've also tested connecting to a RHEL 6 server multiple times to get the data I need. what I mean by this is instead of connecting to a RHEL 6 server once and collecting data I've tested connecting to a RHEL 6 for each command I need so connecting multiple times and there are no issues with the above commands I'm issuing.
Perhaps I'll just need to identify RHEL 6 servers and gather their data differently than I do for RHEL 7 severs but before I do that I thought I would check this forum for any advice first.
I tried doing
ftp myhost <<HERE
username
password
quit
HERE
but it doesnt work. Why?
When I do ftp host, I always get prompted for username, and once I type that in I get prompted for password. But when I try doing it from here document it freezes. (2 Replies)
Hello all,
I am planning to deploy a configuration / auditing software package for about 100 new nodes that we are planning to install. I am hearing many good things in regards to cfengine and puppet. Can someone shed some light in regards to these solutions?
Thanks,

Have a sudo statement inside of a here document. It prompts me for a password, but doesnt wait for me to enter my password. Is there a way I can use the command without sudo or anyway that I can enter the password correctly?
Eg :
while read remotehost
do
ssh -t $2@$remotehost <<REMOTE... (13 Replies)

I am being pushed from AIX onto RHEL 6 and after our first 'chuck it on' install, I have a problem. Where is the old (okay insecure) telnet & ftp server? I know that they are probably regarded as archaic now, but the source servers do not have the SSH tools, so I've got to somehow transfer the... (4 Replies)
