I've actually had some time to look into this today, and with 'some help' from google I think I have it sorted out. Or will when I get the wrong lines right!
While I'm at it, could someone please explain why:
Code:
-# command="user@192.168.xxx.xxx"
-#*echo $command | cut -d'@' -f1
-# user
gives no output? Or at least an empty line. Do I need to present the variable in brackets or quotes? I've tried every combination that makes sense from examples in help topics.
Thanks.

Thanks folks so far...
Corona688, that certainly helps me set the flag.
RudiC, -o ConnectTimeout doesn't appear to be part of this branch of Debian.

I have a linux box build11 which can be pinged from build18 (Windows) box. And we can only login to the box (using SSH) from build18 box. Plz help to characterize the problem, network, DNS, DHCP, etc (or whatever which I am unsure)
Any idea what may be the reason ? :confused:

Hi,
I am writing a script on Solaris 10 and want to execute a remote ssh command. Normally this command should just return the value 0000000000002356 but when using ssh it seems it is passing the result to the shell to execute.
ssh root@10.5.112.145 `/usr/bin/nawk -F\, '$1=="USG" && $2=="01"... (3 Replies)
I have a Solaris 9 server that does not return a ping. When I try to log in via SSH I eventually get in. I am logged in now.
I know this is a wide open question, but can you recommend some things I should check?

Thanks in advance,

rds-ping
RDS-PING(1) BSD General Commands Manual RDS-PING(1)NAME
rds-ping -- test reachability of remote node over RDS
SYNOPSIS
rds-ping [-c count] [-i interval] [-I local_addr] remote_addr
DESCRIPTION
rds-ping is used to test whether a remote node is reachable over RDS. Its interface is designed to operate pretty much the standard ping(8)
utility, even though the way it works is pretty different.
rds-ping opens several RDS sockets and sends packets to port 0 on the indicated host. This is a special port number to which no socket is
bound; instead, the kernel processes incoming packets and responds to them.
OPTIONS
The following options are available for use on the command line:
-c count
Causes rds-ping to exit after sending (and receiving) the specified number of packets.
-I address
By default, rds-ping will pick the local source address for the RDS socket based on routing information for the destination address
(i.e. if packets to the given destination would be routed through interface ib0, then it will use the IP address of ib0 as source
address). Using the -I option, you can override this choice.
-i timeout
By default, rds-ping will wait for one second between sending packets. Use this option to specified a different interval. The timeout
value is given in seconds, and can be a floating point number. Optionally, append msec or usec to specify a timeout in milliseconds
or microseconds, respectively.
Specifying a timeout considerably smaller than the packet round-trip time will produce unexpected results.
