Nov 25	comment	Can only access my webserver from my computer? Check with your ISP if they support a home webserver. I am really worried about that since I saw the private space address in your traceroute.
Nov 25	comment	Can only access my webserver from my computer? It means it is listening on all interfaces, which is good in most cases.
Nov 25	comment	How do I compare a file with a floppy image and the actual floppy's content? @Gilles: you forgot the spaces I put in `<( dd if=/dev/fd0 )`. But OK, you made your point; I just wasn't sure if a plain `/dev/fd0` would read from the device rather than checking the device node itself. That's why I added the black magic `<( ... )`.
Nov 25	comment	How do I compare a file with a floppy image and the actual floppy's content? I like my answer better just because it manages to use bash's black `<(...)`-magic ;o)
Nov 25	comment	Can only access my webserver from my computer? What does `netstat -an \| grep LISTEN \| grep :80` output?
Nov 25	comment	Can only access my webserver from my computer? You have to wait a little while until 200.228.244.6 answers. That way we know how many hops are in between. On the other hand, `10.14.0.1` indicates that your ISP is using private space IP-addresses internally, which may very well mean that they won't/can't support customer side webservers.
Nov 25	comment	How do I compare a file with a floppy image and the actual floppy's content? `cmp` is a drop-in replacement for `diff` in this particular case. Kudos to Gilles for the `cmp` hint.
Nov 25	comment	Can only access my webserver from my computer? Just click `edit` right below your question
Nov 25	comment	Can only access my webserver from my computer? Can you add the output to traceroute 200.228.244.6 to your question? That is about where I loose track of the hops: i.stack.imgur.com/MAcJ0.png
Nov 25	comment	Can only access my webserver from my computer? Not saying it is untrue, but I never heard it before, also my Apache certainly isn't listening on port udp/80.
Nov 25	comment	Can only access my webserver from my computer? Good answer, but why udp/80?
Nov 25	comment	Can only access my webserver from my computer? From my IP address I can't come past: ` 13 bb160006.virtua.com.br (187.22.0.6) 376.304 ms 375.065 ms 375.200 ms`, which is an IP that belongs to your provider. But I am unsure how many hops are left to your IP address. Some providers block port 80 in their corporate firewall, did you check their policy?
Nov 25	comment	Can only access my webserver from my computer? Connecting to 186.207.14.136:80... failed: Connection timed out.
Nov 25	comment	Can only access my webserver from my computer? You have to explicitly do that, Apache won't do it for you (which is a good thing security-wise). I cannot connect to your webserver, so you probably still don't have port forwarding in place.
Nov 23	comment	What's wrong with these two cron job's? You definitely want to check a question of mine. It has an answer by Stephane Chazelas that explains how you can create an interactive shell that is identical to the environment your cron job will see. If you walk through his little procedure, you get a prompt and you can test your cronjob step by step and see where it fails. unix.stackexchange.com/a/56503/16841 Sure it isn't a 100% match for your question, but it can help you troubleshoot crontab issues.

Nov 23	comment	Interactive shell with environment identical to cron Never noticed the mail headers containing some of the environment, by default Thunderbird hides these from the user. The headers unfortunately, do not represent complete the complete environment.
Nov 23	comment	how do I run a cron job with a specific user? You definitely want to check a question I asked about an hour ago. It has an answer by Stephane Chazelas that explains how you can create an interactive shell that is identical to the environment your cron job will see. If you walk through his little procedure, you get a prompt and you can test your script step by step and see where it fails. unix.stackexchange.com/a/56503/16841 The only gotcha is that the first command after the procedure has to be `/bin/bash`, without the she-bang `#!`.
