@MartijnCourteaux This would be a case where you should talk to the local network administrator (which is obviously not you) about integrating your device into their network.
@MartijnCourteaux Ping is an ICMP echo request. It's a portless transport-level protocol. It runs at the same level as TCP/IP. It can be blocked, mangled, redirected, or ignored just like anything else.
Compared to other IP protocols ICMP is fairly small, but it does serve a large number of disparate functions. At its core ICMP was designed as the debugging, troubleshooting, and error reporting mechanism for IP. This makes it insanely valuable so a lot of thought needs to into shutting it down. ...
@voretaq7 I get so tired of people who confuse Ping with the entire ICMP set. Took me the better part of a year to convince boss @ $job[-2] of that one.
@MartijnCourteaux Please stop grasping at straws before you break something. Take 5 giant steps back from the problem and contact your local network administrator.
@MartijnCourteaux If you want to hang out and chat and learn some stuff, then that's cool. We like when people hang out in here. Even non-sysadmins. Everyone is welcome. But stop asking us how to get around your network policy! If you don't, the tone is going to get a lot less friendly very quickly.
@MartijnCourteaux I think a better use of your time would be to go talk to your Network and/or Systems Administrator so they can help you figure out what you need to do to operate in the environment they manage.
Learning network architecture is certainly useful, even if you still just write code having a base understanding of other fields really helps with context.
Attempting to reverse engineer the architecture and policies that are being enforced is rather jumping into the deep end without being able to swim, without an O2 tank, and without knowing how deep it is.
@MartijnCourteaux While the rules in the FAQ are not as strictly enforced in chat, the one about not discussing circumvention of system security or local policies is absolutely in effect. If you want to solve your "problem" you must talk to your site's network administrator.
Just because a student doesn't understand a policy and thinks that it should be circumvented doesn't mean they understand the impact it could have on other students.
Yeah. I'm an Information Security Analyst at a University. I have worked with students and faculty many times. I just don't much care for the ones that cause me to begin a formal investigation.
@ScottPack Martijn Courteaux I say old chap why you still here having a good old moan about the heartless administrators of you college network it's falling on deaf ears you know. Chin chin

if ( $line =~ /sd|hd|cciss|zd/ ) { # just IDE or SCSI disks

Over the years, I added "cciss"
and I just added "zd"
I'm using a messed up combination of XFS running on top of ZFS on top of HP RAID controllers on top of CentOS.
@ewwhite So /zd[0-9]+p[0-9]$/ will match zd followed by any number of numbers (except zero) followed by a p followed by any single number at the end of the line
> Perl has several abbreviations for common character classes. (These definitions are those that Perl uses in ASCII-safe mode with the /a modifier. Otherwise they could match many more non-ASCII Unicode characters as well. See Backslash sequences in perlrecharclass for details.)
In particular, on a Gen8 box I'd be likely to get the email ewwhite pasted, an email from our monitoring system (talking snmp to the same agent) and an email from iLO itself.
I particularly like the agentless iLO-itself thing for things like ESXi where maybe we don't have to bother figuring out how you get the freakin' agent installed this time around...
One of our Dell ESXI servers had a drive fail with an evil click of doom. Naturally, the front status light to indicate this problem is a blinking green light.
(there's two lights, "hard drive icon" and "heartbeat icon". healthy drive: heartbeat solid green and drive light flashes with activity. This failed drive: drive light off and heartbeat flashing green)
or maybe the heartbeat was out and the drive light was steadily flashing?
[0-9] isn't equivalent to \d. [0-9] matches only 0123456789 characters, while \d matches [0-9] and other digit characters, for example Eastern Arabic numerals ٠١٢٣٤٥٦٧٨٩
