Greetings,

Now that I have been trying BLAG for the past couple of weeks, I have to
say that it rocks! It is one of the coolest and most functional Linux distro
I have used/tried in recently.

I have run into these couple of issues:

(1) When I insert a USB Flash drive, can't tell where it is mounted?
Nothing under /dev/sdaX or /dev/sdbX. Do I need to format it for
Linux?

(2) My internet connection stopped working mysteriously. Reconfigured
eth0 (via redhat-config-network), rebooted the machine a few times but
still the same problem. I am connected to the world via Linksys router
and a cable modem. (My connection is up now but not sure how or why!)

Any pointers/suggestions/helpful hints would be appreciated.

Cheers.

You don't need to format it for linux, assuming it has already been formatted. You can format it, if it is unformatted. To mount it:

Code:

mkdir /mnt/usbflash
mount /dev/sda1 /mnt/usbflash


If it's vfat (windoz format), you could also try:
Code:
mount -t vfat /dev/sda1 /mnt/usbflash


To find out more about the device, you can run (as root for more info):
Code:
dmesg
lshw

I don't get it. Umm, it stopped working, but you're connected??? It could be the cable modem connection. Linux doesn't really just drop it's connection out-of-the-blue. You generally don't need to reboot either. Sounds like something else is going on. To see if your ethernet connection is ok, run:
Code:
/sbin/mii-tool eth0

That will tell you if the ethernet cable is connected ok or not.

The best test to see if it's your linux box or the upstream connection is to ping your gateway/router. To find your route run:
Code:
/sbin/route

And look at the "default" line. Then ping your gateway/router's IP:
Code:
ping 192.168.1.1

Substitute your gateway/router for 192.168.1.1.

If you're pinging OK, then the problem is upstream. To stop the ping hit ctrl-c.

Ciao,

-Jeff

Jeff,

Thanks for your quick repsonse.

USB Flash Drive:

dmesg shows me the following:

Quote:
usb.c: USB device 2 (vend/prod 0xea0/0x2168) is not claimed by any active driver
.
Initializing USB Mass Storage driver...
usb.c: registered new driver usb-storage
scsi1 : SCSI emulation for USB Mass Storage devices
Vendor: MicroAdv Model: QuickiDrive128M Rev: 2.00
Type: Direct-Access ANSI SCSI revision: 02
WARNING: USB Mass Storage data integrity not assured

SCSI device sda: 256000 512-byte hdwr sectors (131 MB)
sda: Write Protect is off

I tried to mount the /dev/sda1 as /mnt/usbflash (as root) per your suggestion.
I don't get the prompt back. Same result if try to mount it as a VFAT.


What gives? Any ideas?

Cheers.

Hmm. It appears that there are 4 partitions on that device. Try mounting with sda2, sda3, and/or sda4. I see that from the line:

sda: sda1 sda2 sda3 sda4

Also, I've used around 4-5 different USB keys and all but one worked well. Sooooo.....
