The following ksh script is trying to get a file's cksum then, scp it over to a remote machine - get the cksum there and then compare the two cksums to make sure they match. I am having problems setting a variable on the remote host where it can be read locally. Is this even possible - reading a shell variable from a remote host? I have the ssh and scp file transfer working properly. The two problems I am having are logging to the remote host's syslog.log and exporting $REMOTECKSUM for comparison. Any help or guidance is appreciated.
Thanks,
berrean
Code:
#!/usr/bin/ksh
MACHINE=$1
FILENAME=$2
DESTFILENAME=$3
#DEBUG echo "connecting to: $MACHINE"
# Get the local cksum and write it to a local log
cksum $FILENAME >> local.log
LOCALCKSUM=$(cksum $FILENAME)
# write an entry to the local syslog
logger -t TESTLOCALCKSUM -f local.log
# do scp here
#DEBUG echo "connecting to: $MACHINE"
#DEBUG echo "filename is: $FILENAME"
#DEBUG echo "destfilename is: $DESTFILENAME"
#DEBUG echo "command is /usr/local/bin/scp2 $FILENAME $MACHINE:$DESTFILENAME"
/usr/local/bin/scp2 $FILENAME $MACHINE:$DESTFILENAME
# Write the remote cksum to a remote log and VARIABLE then log this in remote syslog
/usr/local/bin/ssh2 $MACHINE "cksum $DESTFILENAME >> remote.log; export REMOTECKSUM='$(cksum $DESTFILENAME)'; logger -t TESTREMOTECKSUM -f remote.log"
if [[ "$LOCALCKSUM" = "$REMOTECKSUM" ]]; then
print -- "CHECKSUMS MATCH --- SUCCESS!!"
print -- "local cksum: $LOCALCKSUM"
print -- "remote cksum $REMOTECKSUM"
else
print -- "CHCEKSUMS DO NOT MATCH --- FAILURE!!"
print -- "local cksum: $LOCALCKSUM"
print -- "remote cksum $REMOTECKSUM"

Thanks to this forum, I was able to get a program running that uses SSH to control programs running on other hosts. Now I'd like to enhance it.
The control program on the target hosts occassionally needs to be updated. Updating the menu program on the source host is easy as it is on one host. ... (1 Reply)

ssh-copy-id
SSH-COPY-ID(1) General Commands Manual SSH-COPY-ID(1)NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys
SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine
DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine and append the indicated identity file to that machine's ~/.ssh/autho-
rized_keys file.
If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
ssh-agent. Otherwise, if this:
ssh-add -L
provides any output, it uses that in preference to the identity file.
If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin-
gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
if necessary.)
NOTES
This program does not modify the permissions of any pre-existing files or directories. Therefore, if the remote sshd has StrictModes set in
its configuration, then the user's home, ~/.ssh folder, and ~/.ssh/authorized_keys file may need to have group writability disabled manu-
ally, e.g. via
chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys
on the remote machine.
