Looks like your eth0 is rd0 from what ifconfig is telling you. change that and use netstart

I'm not sure, but I guess I also want to ask the question why would you need to as long as it works? From what I know BSD detects devices with names slightly different from Linux just as Solaris does as well, is this a normal hardwire jack on a motherboard or LAN card?

Oh, I see what you mean. I meant since ifconfig is showing your device as re0 you should put re0 in the rc.conf instead of whatever is in there already. PM me directly if you need further help or if you don't get what I mean, I can message you on aim or something.

I'm not sure where else to post this, because it's kind of a low-level question, but I installed Ubuntu tonight, and while it's been for the most part an enjoyable experience, I'm having trouble installing flash, and getting Amarok to make a library out of my music on another hard drive.

For the flash issue, it says

code:

----------- Install Action Summary -----------

Adobe Flash Player 9 will be installed in the following directory:

Mozilla installation directory  = /home/<me>/.mozilla

Proceed with the installation? (y/n/q): y
cp: cannot stat `/home/<me>/Desktop/flash/libflashplayer.so': No such file or directory

NOTE: Please ask your administrator to remove the xpti.dat from the
      components directory of the Mozilla or Netscape browser.

chmod: cannot access `/home/<me>/.mozilla/plugins/libflashplayer.so': No such file or directory

Installation complete.


Perform another installation? (y/n):

I cannot for the life of me try to redirect that "Mozilla installation directory".

As far as the Amarok thing goes, when I go to add songs to my library, it just doesn't give me the option to go to another hard drive.

I'm trying to approach this with as much modesty as possible. I didn't want to just jump in and act like I knew everything and then bitch when I fail, but I didn't want to approach this like an old woman and just assume I couldn't do it either. I can live without the Amarok thing, but I'd like to do bigger things than stumble over flash all day long. Beryl looks cool, and I'd like to see what other stuff there is to do.

I assume you are attempting to install flash from the adobe website? Have you tried to install flash from synaptic?

you should be able to install from command line with :

Ok, I need an app that will automatically get album art for me. Based on folder names tho. And recursively.

so if my root folder structure is:

code:

music
 |-Dillinger_Escape_Plan-Ire_Works-2007
 |-Radiohead
   |- radiohead - ok computer
   |- radiohead-hail to the thief
   |- thom york - the eraser

so hopefully something that's smart enough to substitute underscores for spaces and so on and so forth.

Here comes a really stupid question

I've got a brand new Debian Etch install up and after apt-get install mysql-server I can't connect to it from the outside. It's just outright refusing to connect.

I didn't install a firewall and I don't know if there is one install by default or not. IPTables is empty and the user I'm trying to connect with has been given % host access in MySQL db privs. I'm not getting a connection denied... Just refused outright

What am I forgetting

It probably only listens on an AF_UNIX socket unless configured otherwise. Configure it to listen for TCP connections.

Not familiar with the distinction between the two unfortunately. This is how it's currently running if it helps. It appears like it should be running on it's default 3306 port.

It's like an initial threshold for mouse movement. The difference becomes obvious when you have acceleration set to lowest and play around with sensitivity.

As long as you partition in a sane way, it's easier with windows first and then linux. Windows will overwrite the MBR, so you'd have to reinstall grub if you do linux first.

Yeah, that's what I was kind of figuring. Wasn't totally sure though. I love Ubuntu, but still need some apps that just won't run with Wine. I'm sure most folks here know the deal already.

Any reason VMWare won't fill that gap? The only reason I've ever needed to boot Windows natively is for performance reasons (e.g. gaming). Otherwise, VMWare (Fusion on the Mac now, or whatever its linux client was named back 5 years ago in the past) works beautifully.

AFAIK their Linux client is still free.

Too much hardware stuff going on. I'm using Nokia PC Suite in Windows, which needs USB access and I'm also doing video editing as well, so I need every ounce of horsepower I can get. Games too.

USB works fine in VMWare.

It does for general purpose stuff like game controllers and mice, but with phones and phone software, it gets a little tricky. Overall, I'd rather just dual boot and be done with it. Sometimes software developers just don't play well with others.

Games, however, would probably be best served in a native environment.

How secure is SSH on Debian?

And by that I mean, is it secure enough to open a port to the SSH port on my Linux test box?

I'm a dyed in the wool Windows admin, but I'm not the kind of Windows guy that sees no use in Linux. I set up a linux test box in a VM, partially to learn more about linux administration, and partially to have an easy way to pop into the network remotely (via Putty).

Basically, I opened a port on the firewall (not 22) that points to the SSH port on my linux box. That is the only port pointing to the box. If I just keep up on updates am I fine to leave it like that, or is there something more I need to do to lock down SSH?

It's fine as long as you keep up with security updates.

It's sometimes recommended to disable root login via SSH (Set PermitRootLogin no in /etc/ssh/sshd_config - or wherever your sshd config file is), other than that I wouldn't worry about it too much as long as you don't have bad passwords.

Being the primary point of remote access, SSH is required to have a high level of reliability/security

I'll disable root logins, since I never use root anyways. I figured it was secure, but I wanted to make sure.

If lots of people have logins on this box, you might want to disallow all of them except you unless you can audit all the passwords to be sure they're strong enough.

SSH is about as secure as it gets, and very well maintained. It's had it's share of exploits, but they're rare and shut down pretty quick, so just keep on top of patches.

You can lock it down pretty tight as well, without too much work. Debian's build is tcpwrapper aware, so you can limit access to specific networks and computers via /etc/hosts.allow and /etc/hosts.deny.

Limit the number of SSH sessions, disable SSH1 entirely, audit failed logins, etc.

You can avoid passwords entirely by implementing public key authentication, and make that more secure by requiring a passphrase.

Really, if you're not running any other services, you should just firewall everything except port 22, and use local tunnels for all your other traffic.

# ? Aug 7, 2008 02:35

uncleTomOfFinland: May 25, 2008

Rather than disable individual accounts you should deny everything by default and allow specific accounts/groups you want to use with SSH. Also running SSH in some utterly random non-privileged port might reduce the amount of "extra" traffic it gets.

Alowishus: Jan 8, 2002; My name is Mud

I'd add DenyHosts to the equation. It's perfect if you are going to be accessing SSH from enough potentially different IPs that using tcpwrappers is impractical... you can set it so that ~3 unsuccessful login attempts from any IP will get that IP blocked automatically. That plus good passwords and you should be in excellent shape.

I prefer doing this on personal servers that nobody else has access to because it basically removes all of the brute force clutter from my logs and makes it easy to spot real intrusion attempts. I was hesitant to bring it up though because using a non-standard port for SSH can evoke nerd holy wars (and I think it did last time I brought it up).

If you plan on doing this the only things you may want to follow are:

1024 < port < 49151

Into The Mild: Mar 4, 2003

I recieved a old-ish laptop from my sister, who was going to throw it away because it was "broken" I ended fixing the battery problem and scored a new laptop.

So I installed Kubuntu KDE4, then quickly went to KDE3... then decided to just try Ubuntu.. and man I'm seriously impressed with Gnome now

The problem is that laptop uses a 855GM graphics chipset and man does the ubuntu copy of the intel driver suck, freezes most times i sleep the laptop, and when starting a video it will crash probably 20% of the time.. just a blank screen, and the cpu fan goes crazy.

I looked into it, and it turns out theres a few people on the ubuntu forums complaining about the intel driver for X with the same problems as me, random blank screen crashes, cpu gets maxed out and you have to hard shut it down.

It's a shame really.

I'm trying out openSuse to see if that distro has any problems... so far nothing.
