Tool to check network connectivity

[Chandrahasa s]

Hi Masters,

I am looking for tool(or script)which will monitor multiple servers connectivity(ping) and send alert if any server found not reachable.
Tool should be opensource and able to install on hpunix system.

Why not write a script yourself?

> [...] send alert [...]

Console message? E-mail?

> [...] on hpunix system.

Then why ask in a Linux forum instead of in
an HP-UX forum?

Shalom,

linkloop.

Take a look at my latest post on http://hpux.ws and steal the linkloop line.

Very good check of network connectivity.

HP-UX only, and btw you posted to Linux.

HP's openview/ITO tool sets and open source hobbit have good network monitoring that do work on Linux and HP-UX

There is a port of linkloop to Linux. it may also be an optional package in SLES11.

Chandrahasa,

Check this out:
The code using here is :
# ping -c n servername
[ -c n is number of packets to send , usually 2 or 3 is enough to determine the status. ]

Hi,

better than searching for a tool, it will be easy to right a small script for this as you want to check only ping.

Apparently you aren't looking for forum
points, either.

You can include

UDN (Unreachable Device Notification)

into your (windows) SMH!

A Forum search for keywords like, say:
ping script
might find several things, too.

Personally, I find "ping" scripts less useful
than (slightly) more complex scripts which
test actual functionality. For example, if I
wanted to know if an FTP or Web server on
some system were working, then I would use a
program like wget to fetch an actual file or
Web page from that server. If some such
_real_ task failed, _then_ I might run a
"ping" test, but it would not be my primary
test method.

Why are you running these "multiple servers"?
Are they supposed to do some actual work, or
are they there only to respond to ICMP echo
requests? Why are you testing them?

I've seen many systems which were hung in
some horrible ways, where the only thing they
could do was respond to "ping". If "ping"
response is what you really care about, then
test with "ping". If something else is what
you really care about, then it might make
more sense to test with something else.

Hi,
As i said we have no. of servers if any server goes down we should get alert saying that server is down.
We have rsp confgured but still we want alternate way also.
