linux: commandline ping on host works, NET::Ping not always

hi using Net::Ping for checking whether our servers/routers are online. in general Net::Ping (with icmp) does work without problems, but there are some ZyXEL Routers (e.g. P334) that seem to be down with Net::Ping but are still pingable via commandline. any ideas? thx michael muelleder

I don't know if this is your problem, but I have discovered that if you use a zero(0) in your IP address, it seems to fail to even try to ping. I was trying to ping 10.212.074.4 and it failed. Once I removed the leading zero in the third octet, it worked. I have also noticed that sometimes a zero in the number will also fail, as in 10.212.120.4. This doesn't seem to follow any pattern that I could see, though. [guest - Fri Jun 10 08:18:47 2005]: Show quoted text

I had problems using "syn" on linux and not Win32. However, I noticed that setting service_check(1) on linux resolved the issue. Mitch

This is a quite a bit late, but would you happen to have the code you were using? Without it, its very difficult to guess what the problem might be.
