Hi, all.

I'm a unix sysadmin at a community college and I've been doing this for about 10 years. I've been thinking and I realised I spend most of my time worrying about upgrades. By upgrades,...

Just kill the ssh process. What do you mean by "sleep option"?

Or maybe you want to open an ssh session to forward the vnc port and then you want the terminal window to go away?

Oh! I just...

That's strange. In the days before network manager screwed up my life, I just had my laptop configured for each network I used and not only did I not have to re-configure if I went out of range, I...

Short Answer:

Yup! That 'w' means read/write. You might have read only drives, such as a CD. You can mount read-only drives on multiple DomUs and you can't do that (without major craziness or a...

Thanks for taking the time to answer! Sadly, I've already played around with the MTU and it didn't help. It's actually balking on packets with almost no data at all in them.

Hi all.

I have a really really weird problem that I've been working on for days.

The problem manifested as users cannot connect to our web servers via SSH when they're using our wireless...

Ding! We have a winner!

If you want the box to shutdown and immediately come back, you can use some variant of reboot. If you want it to shutdown and then come back at a later time, you're SOL...

Is Exim not restarting? Is the only problem that it's printing the file names or is there something else that isn't working? Does /etc/init.d/exim4 match the version from the packages you used to...

You want to execute a script that just prints the contents of itself? You want the output of "./abc" to match the output of "cat abc"? I don't think that's an easy problem to solve. Or do you not...

What about "cat dead.letter | sendmail addess@example.com" ? I'm just making a wild guess so please, those of you who know better, feel free to throw ripe fruit at my head.

I recommend using ssh-copy-id (http://linux.die.net/man/1/ssh-copy-id). This makes sure the permissions, file names etc.. are all correct. If you don't want to give the user a regular password, you...

Since no one has answered this in 2 days, I'm going to go ahead and give more general advice. I know nothing about iperf, 802.1Q, MPLS, VRF etc...

What are you actually having trouble with? What...

When you say "copy a file" do you mean you want to copy one specific file one time or do you mean you have a reoccurring need to copy files?

Using scp is almost always the best option. It's...

Maybe you're actually including a different A.h than you think you are. That's what this smells like.

If you want to get to the bottom of this, make the smallest code you can that recreates...

What is the test that it's failing? That's a big hint right there.

Also, you can do something like

strings devbinary > strings.dev
strings buildbinary > strings.build
diff -u strings.dev...

You got single quotes (') around the sed command. You need to use double quotes (") for $NUMBER to get processed by bash.

What does that mean? What do you mean by "orphaned"? Elevating a process to root privileges isn't the sort of thing your system should do.

If you're on Linux (or any system where lsof acts like it does on Linux), you might want to run

lsof +L1 | sort -n 7

This lists open files that have been deleted and then sorts them by size.

What are you actually trying to do? I don't know anything about LINE_MAX, but I might be able to help with the more general question?

If LINE_MAX is the limit of the pattern you can define, that...

I also have this problem. CentOS 5.2 - any rpm command might cause floating point error. It seems to be somehow time related. Running ntpdate and then trying again seems to help.

Is there an SFTP server for windows? What about SCP/SSH? If you're copying from Windows to Unix, scp and sftp are the obvious choices, but since you're copying from unix to windows, the answer...

Okay, I read the error again and I can say with even more confidance that you can ignore it.

NOTICE: <- this means it's a notice, not an error

Tape ... not ready <- This is probably a temporary...

Are you saying the only problem is you see this error in your log? If it's not stopping you from getting work done, it's probably not worth spending any more time on.

If you rebooted it and it went away, then you have two options:

1) Go crazy trying to make the problem re-appear. This will use tons of your time and make the machine unusable for other work. ...

We need more info before we can help. What are you trying to do, what happens etc.. Read a few posts from other users to get a feel for what I'm talking abuot.
