And curl worked for me with the addition of the '-L' flag. What message (or error?) do you see when you try it?

Here's the version of curl in case you want to compare.
curl 7.22.0...

Got it... But unless I'm missing something, once an IP is on your firewall's block list any packets received will be ignored. So the only "SYN_SENT" connections will be the ones setup before the...

I think it's better to block the IP's with iptables (or the ufw front end to iptables) then just killing the connections. Presumably someone that's trying to attack your system would just reconnect,...

If it helps, there's a program called "quipi" in this GitHub repo (mine) that does address lookups and runs through the resulting records to pull out data.

There's a couple things that make it hard to just give you a suggested solution...

First, the structure you're talking about it generally not just one structure. It's a linked list of structures,...

Other people might have the same question I do, which makes it difficult to suggestion a solution. I'm not sure what "fully loaded" means?

If you just want to know if the website is up and...

If you have to do this, which is sounds like is the case, then I suggest you maintain the list of password as hashed/encrypted passwords. That's not hard since you are presumably generating them in...

If the IP's you're getting from "dig" aren't associated with the server running Apache, then HTTP requests sent to that domain aren't routed to the Apache server directly.

So if they are getting...

I wouldn't rely on the "file" command to provide any definitive answer about the intended use or format of a file. It's notoriously inaccurate and IMO is more of a "hint" for interactive use then...

The answer to how that program work are in the URL you linked.

The called program overwrites it's arguments after making a copy of them. But as one of the other comments adds, there's still a...

Here's a really crude thing I threw together just now that worked for me. Some variation on this, which just gets a list of files and checksums with "ssh", might help.

#!/bin/bash

for hh in...

There's also a "flock" command (as opposed to the library routine of the same name) available which may be pre-installed or at least pre-packaged on the systems you care about. It does exactly what...

If you're using bash/sh or similar shells this will capture the python version number in a variable.

xx=$(python --version 2>&1)

The output is being sending to stderr, which is why you need the...

If you're already running "find" why not just put the "rm" command there?


find /usr/IBM/HTTPServer/apache_cache/ -type f -mtime +1 -exec rm {} \;

I don't understand the requirements well enough to give you a complete answer. But here's a sample of how you can use "pkill" (if you system has it) to determine if a process is running or not. I...

This syntax also works, at least in bash.


if [ -s file1.csv -a -s file2.csv ]

You probably already know this, but just in case... Paging and swapping are not the same thing and your OS could be doing one or both.

As for finding out what's going on in more detail, I'd...

I think if you have a 15MB shell script it's going to be slow no matter what. So if speeding things up is important the best approach is, unfortunately, to redesign the script and break functions...

If you're running bash, then this should work.

FCD() { dir="$(find . -name "$1" -exec dirname {} \; | gawk 'NR == 1 { print }')"; if [ "${dir}" != "" ]; then echo "change to '${dir}'"; cd...

That was my first thought too. If you are already using "scp" then I'd recommend setting up keys that allow you to "scp" without needing a password. Then your scripts get much, much simpler.

The file "/proc/###/smaps" has all sorts of useful information about memory usage of individual processes, including swap space. It's way more detail than you're looking for but you can extract what...

You can use the mktime() and strftime() routines if your awk has them (gawk does). Here's a crude sample to give you an idea how it work. Check the "man gawk" page for more info

gawk 'BEGIN {...

Hmmm, if the sample data is representative then it's not even necessary to take the "ID=" field from an earlier record. The value you want it already in the "ID=" field of the "exon" record. You...

Here's a quick demonstration how "flock" can be used to coordinate serialized execution of a command. When you enter the following,


iter=0
while [ ${iter} -lt 10 ]
do
flock -w 30...

Eons ago I ended up writing C code to wrap execution of arbitrary commands with lock management just for cases like this. Meaning, I needed a way to coordinate the use of various scripts, tools,...
