Re: remote ssh commands

[Nadim Hoque]

Sean,

Well when I just run the 'yum update -y' it runs it just fine but the &&
poweroff runs on the local machine. Also I have another script that does
the following:
#!/bin/bash

for server in $(cat serverlist.txt); do
   ssh  $server.localdomain 'poweroff'
done


and also running that just powers off the host. It seems that it will
execute all except the poweroff command on remote servers

 Fellow Pluggers,

 So I am trying to perform a remote poweroff command and for some reason
 the host powers itself off. I am able to run another command such as yum
 just fine but when I try to execute the poweroff command the host turns off
 as well. Below is the script that I am running



 #!/bin/bash

 for server in $(cat serverlist.txt); do
ssh $server.localdomain 'yum update -y && poweroff'
 done

 Also note that the serverlist.txt does not contain the host itself.
 Thanks for the help.

Re: remote ssh commands

[Brien Dieterle]

You probably have a blank line in your serverlist.txt, resulting in
$server being null:

ping .localdomain
PING .localdomain(localhost (::1%1)) 56 data bytes
64 bytes from localhost (::1): icmp_seq=1 ttl=64 time=0.017 ms
64 bytes from localhost (::1): icmp_seq=2 ttl=64 time=0.022 ms

Re: remote ssh commands

[sean]

Could a bad dns record or host entry point one of the lines in the file
back to itself?

Is the yum update also being run on the host? Try a different command in
the loop, e.g. 'echo $server > /tmp/test' should be a good troubleshooting
start.

Re: remote ssh commands

[Nadim Hoque]

Its a virtual to virtual setup. All the guests are on the bridge connection
that I have made so that they are on the same network. To answer your
question I am not touching the VM host at all.

Re: remote ssh commands

[sean]

Are you running this on a virtual machine? If so, are you powering off its
host machine?

remote ssh commands

Fellow Pluggers,

So I am trying to perform a remote poweroff command and for some reason the

fine but when I try to execute the poweroff command the host turns off as
well. Below is the script that I am running



#!/bin/bash

for server in $(cat serverlist.txt); do

My printer died.

[Keith Smith]

Hi,

My all-in-one HP printer just died.  It gave me 8 years.

Recently someone mentioned that Brother makes a very good quality 
printer.  Had one about 16 years ago and swore them off...  Maybe 16 
years is long enough.  Looks like Staples has 
http://www.staples.com/Brother-MFCL2700DW-Mono-Laser-All-In-One-Printer/product_1174233?akamai-feo=off 
on sale for $149 and the toner cartridges seem to be decent priced also. 
 $50 for 2600 prints.


Any other suggestions. Fax/Printer/Copier/Scanner.  Would like with rj45 
so I can config on an IP.   Will be printing from a Win 7 box and a Mint 
box.


I'll be making the purchase tomorrow morning.

Thanks in advance!!

Keith
