Did you check your router DNS settings? are they what you expect?

comment How do I create an account that can only use the ls and cd commands?
I think @davidgo is right, you need to write your own shell, which is very hard. The "need to be root equivalent" and "restrict to a mindnumbingly small list of constraints" are polar opposites. You rally need to think this through.

comment What's a good test for a very non-geek to verify dropped packets?
Yeah, I think that's it. I thought there was a stream-ping test URL someplace. Just trying to get them to call someone else is an issue :)

Sounds good, I may make accept this as the answer, but echo is audio only. I'd prefer a higher bandwidth answer.

Thank you. But this is too low level for them. I need a "click this link" level of saying yes/no packet drops are occurring. Then they may call their ISP to fix it.

Id specify whether or not you want to see if aliases or functions shadow commands.

comment Does DNS locate on local network?
@ethanjyx DNS is just to match up hostnames to IP addresses. Any IP addressed machine that you want to get by hostname, by whatever protocol, including (but not limited to) http, ftp, telnet, ssh, sftp, sip, ping, traceroute, etc) you would use DNS to get to.

comment How Does Mega.co.nz detect your user agent?
It could possibly be using some recent chrome api. If it tries to use SomeFunctionOnlyInChrome29andAbove() whatever you spoof in 26 won't help.

comment Manually closing a port from commandline
@codingfreak The kernel knows the process is gone. It knows it can reclaim the port. There are actually rules on the timing of closing the port, to make sure there aren't any stray packets floating on the 'net. How does it know it has these resources? that's what the kernel does, keeps track of things.

Possibly related: -r and file globs don't do what you want usually.

comment How To Rotate A File in HP-UX
is the output file being written to why you're trying to rotate? if so, you have a race condition, you can't do this. Normal unix is to (1) rename the file, have the process reopen files after receiving SIGHUP (2) have the process write logs to stdout/stderr and pipe to a logsplitter like httplog

comment How can I cause Fedora Linux to show me the GUI login screen?
what does runlevel return? What about grep initdefault /etc/inittab In most Linuxes, you start gdm at runlevel 5. Not sure if latter Fedoras change this convention.

comment How to transfer files from a Mac (OS9) to a Window 7 (or XP) PC using a direct ethernet connection
Are there other file sharing protocols available on the NAS other than Windows/AFP? You'd be much better off using that than the NAS => Mac => Windows box. The NAS may support FTP, SCP, or NFS. Cygwin may help on the Windows side. Also check Web Sharing from this doc

comment Why does my browser try to open ads from fwdsnp.com?
They really should have said change their ISP :) They shouldn't do this. For DNS, the two big ones are Google DNS (good cause they are fast, bad because that's yet another bit of info you send Google) and there's OpenDNS.

comment FTP cmd works but other FTP clients fail?
quickie guess: are all clients configured the same for passive vs. active ftp? Chrome should default to passive though. Not sure about FireFTP

@somequixotic yeah, i thought of that after i posted. I was already editing it. Thanks though.

comment Remove lines matching string in grep
1) you don't need extended grep for this, the expression is "non-extended". 2) this will only remove lines where the comment is the first character, which is not part of the requirements 3) the .* is unnecessary in this case, though is useful sometimes with grep -o

comment How to schedule/unschedule cron job from shell
I'd also check to see if there is a process that matches your PID (didn't crash and leave tmpfile). read PROCPID < /tmp/core.pid; [ -w /proc/$PROCPID/mem ]; would be a good test on Linux.
