Time Event
backing up linux...
hey guys

can someone provide me with the skinny on tape drives? i have several questions on the subject but little experience. here are the questions in specific.

1. how would a tape drive be typically used?

2. how does the software work? ie - do you typically select ahead of time what files/directories to backup or do you decide it manually every time? - or does it only do entire drive images?

3. if you have a 120Gb drive that you have decided to backup onto tape, but you only have say 20 gig tapes, will it let you do multiple tapes or are you regulated to manually selecting 20 gig chunks of data?

4. can you use this to backup individual remote systems on a network? for example, as a sysadmin can i have a machine on the network backup the data from another machine over the network? will the software allow that?

5. how does accessing the data usually take place. can i access the data and recover one file or is it a complete image - an all or nothing kind of restore?

6. are there tape drives that will fit into a standard 5.25 inch drive bay?

7. are tapes reuseable or are they one shot one kill things like dvd's and whatnot?

8. is there some software to drive these that you like better than others or can recommend?

thanks guys for any or all information you can supply me on the subject.
two internet connections - eth0 and ppp0 - how to set up?
Hello All,

I've recently gotten on a satellite connection and it's nice for downloading large files. I've also got a dialup connection as a backup. There's no other options here for high-speed access. I notice that working via SSH is terrible slow on the satellite because of the lag, but bearable on the dialup.

Is there any way for me to have *both* of these connections working at the same time, so I can use them both for internet access? I can connect to them both, but only the satellite will work if I connect via dial-up after I'm on the satellite. Here's my output for route when in that senerio. eth0 = satellite, ppp0 = dialup.

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
h1.152.102.166. * UH 0 0 0 ppp0 * U 0 0 0 eth0 * U 0 0 0 eth0 * U 0 0 0 lo
default UG 0 0 0 eth0

anyone have any idea how I can use both connections at once?
Before I start a rather complicated scheme of using encrypted loopback filesystems for storage, I'd like to ask: Is it as easy to resize loopback (ext3) filesystems (with tools like parted) as it is to resize ones on physical partitions? I'm okay with using command-line tools.

Hmm. For that matter, I have no idea how I would go about resizing an encrypted filesystem at all. I'll have to look into that. But for now, I'll just worry about the loopback problem.

This is assuming there's no way to make a truly dynamic-sized loopback filesystem, of course. That would be convenient, but maybe too technically difficult to implement.
Well duh...

Linksys WMP11
I just installed the Linux 2.6.1 kernel. I would like to get my Linksys WMP11 (It's an 802.11b wireless PCI card). I was not able to get it working under 2.4.22 either.

I am currently attempting to use the following driver to enable support for it:


I followed all instructions, however upon system startup, I receive the following messages after the "modprobe" command is run.

wlanctl-ng: No such device
wlanctl-ng: No such device
SIOCSIFADDR: No such device
wlan0: unknown interface: No such device
SIOCSIFNETMASK: No such device
SIOCSIFBRDADDR: No such device
wlan0: unknown interface: No such device

Suggestions? Advice? Thx.
I just read this story on slashdot about Intel and the up comming Centrino WiFi drivers. I was one of the first people who got a Centrino laptop and installed Linux on it. I do not need WiFi since the places I goto have both WiFi and ethernet ports. Ive held off on installing ndis or buying another WiFi card, but have been eager to install native WiFi drivers. When I e-mailed Intel about drivers in late aug they said drivers should be comming out in the 4th quarter of 2003. Well its gone and past and still no drivers. Do you think this means that the drivers are going to be comming out soon? If they are does this mean they are going to be as good or even better then the Win drivers? Is Intel getting friendlier to Linux?

HTML Editor ...
Anybody know of a good HTML editor that offers preview while editing code? Something like Dreamweaver perhaps?

Could I run Dreamweaver in wine ... or would that demand a lot of CPU and RAM?

Current Mood: curious
I just fired up Links for the first time, and it's very speedy compared to Mozilla, but everything in it feels broken. Like, I can't submit forms and have them work right. I can't copy text out of the text box, or even highlight it to copy it, and paste it into a text box of a mozilla window that will work, so instead I have to re-type it.

I'm not sure if the problem is that links sucks or that http sites are put together by people who have no regard for standards, user error, or some combination thereof, but it'd be a damn spiffy browser if I could actually use it for anything. I'll try RTFMing and see if that helps...

I actually like the interface, it has a pleasingly clunky old-school feel to it... if only it actually worked and had a few more options to it than it does. Maybe it'll get better?
i just finished installing debian via the sarge network install cds. everything is running smoothly except for the fact that i have no sound.
im using an audigy, and i have tried everything i can think of to get it working again (including compiling the 2.6.1 kernel with audigy alsa drivers).

any help would be greatly appreciated.
Since we seem to have an abundance of experts on Links and terminals, I figured I'd follow up on my earlier post...

Collapse )

Running Mandrake 9.2 on a dual Pentium Pro 200 with 512MB of RAM I scrounged together from various inexpensive sources.

Anyway, KDE is pretty bloated but it's usable for a Windows/Mac guy like me who's trying to learn what I'm doing. But due to the bloat and the speed of my hardware, I am really liking Links now that I tried it, because it is actually pretty fast.

But from the sound of things, Links isn't properly configured on my system, though I haven't DONE any configuration (maybe that's the problem?), as the behavior I'm seeing doesn't match up with what I'm reading about in the comments from the earlier post.

So... couple of questions.

First, if I run Links outside of a terminal session, ie directly in KDE, I get images to display when a page renders. If I run Links inside of the Konsole terminal, I just get plain text with no images. I take it that's because the terminal doesn't have the sorts of routines needed to dispay anything but text, am I right? Or is my understanding flawed and in need of remedy?

Second, I can't highlight text, nor can I copy/paste it. Where would I begin to look to troubleshoot this? is this likely to be a Links-specific config file issue? Or is it more likely to be an X issue?

Third, why can't I click on buttons to submit forms for stuff like logging in to a website, or using web-based email? What needs to be enabled for this to work?

Thanks, all, for the lively discussion and any help and especially insight you can bring to the table.
