Top Forums Shell Programming and Scripting Linux: Writing a tricky script to check connectivity Post 302284214 by kungfujoe on Thursday 5th of February 2009 02:09:28 AM

Thanks for the replies guys.

Yeah, it's a Motorola Surfboard.

Ok, so, as for layers of dependencies, That seems deep for me. I'm trying to keep this simple. If it can't ping, I don't really care why, I just care to fix it (And I know it would be more efficient to find the actual problem, but I'm taking a more general stance, ie, If the roof leaks, it's cheaper and quicker to find the leak, but replacing the whole roof works too.).

I'll take a look at the guides, but what I'm really asking is that, with the knowledge that I can, in fact, SSH into the modem and pass it the proper command, Is the rest of it POSSIBLE?

I'll figure it out, but I need to know if I can have a script:
Run every 5 minutes
Save information about a ping in a useful fashion (ie, variable containing time in ms, or a failure state)
SSH (I'm pretty sure this one works, could someone confirm that scripts can SSH?)


If you guys could tell me (if you know) if these things are possible, I'll figure out how to implement it all, but I don't want to spend hours learning scripting only to find out that some of these break rules or aren't possible for the language to handle.

Thanks
KFJ

Xsession.options(5)						File Formats Manual					       Xsession.options(5)

NAME
Xsession.options - configuration options for Xsession(5) DESCRIPTION
/etc/X11/Xsession.options contains a set of flags that determine some of the behavior of the Xsession(5) Bourne shell (sh(1)) script. See the Xsession(5) manpage for further information. Xsession.options may contain comments, which begin with a hash mark ('#') and end at the next newline, just like comments in shell scripts. The rest of the file consists of options which are expressed as words separated by hyphens, with only one option per line. Options are enabled by simply placing them in the file; they are disabled by prefixing the option name with 'no-'. Available options are: allow-failsafe If the 'failsafe' argument is passed to the Xsession script, an emergency X session is invoked, consisting of only an x-termi- nal-emulator(1) in the upper-left hand corner of the screen. No window manager is started. If an x-terminal-emulator program is not available, the session exits immediately. allow-user-resources If users have a file called .Xresources in their home directories, these resources will be merged with the default X resources when they log in. allow-user-xsession If users have an executable file called .xsession in their home directories, it can be used as the startup program for the X session (see Xsession(5)). If the file is present but not executable, it may still be used, but is assumed to be a Bourne shell script, and executed with sh(1). use-session-dbus If the dbus package is installed, the session bus will be activated at X session launch. use-ssh-agent If the ssh-agent(1) program is available and no agent process appears to be running already, the X session will be invoked by exec'ing ssh-agent with the startup command, instead of the startup command directly. All of the above options are enabled by default. Additional options may be supported by the local administrator. Xsession(5) describes how this is accomplished. AUTHORS
