Charter Telephone reviews, boylston?
by John Stoffel
Hi,
Anyone on here using Charter Telephone VOIP service? I've currently
got Verizon, but the wife hates it because our phone lines get flaky
all the time, esp when it rains.
So I'm thinking to save money and combine all my stuff onto Charter.
I've already got High Speed internet and regular old cable. Not wild
about Digital Cable since I'm happy with Tivo and I don't want yet
another set top box to have to deal with...
So, any horror stories about Charter Phone VOIP quality and service?
Thanks,
John

SSH problems
by Eric Martin
I have an outward facing ssh box at work that is currently being
attacked. somebody's going through a dictionary attack of usernames;
currently he or she is on abl. I can't block the IP Address because the
ip is different with each username. Does anybody have any good ideas on
how to stop this? I'm probably going to move the ssh port to some
random high number to get rid of this, but I don't know yet if anybody
else ssh's in besides me.
Thanks in advance

Funky LVM hack we talked about...
by Tim Keller
Hey Gang,
For those of you at the meeting who don't remember, Kevin had a 32GB flash
disk that had a controller that had a built in understanding of FAT32. Thus
formatting it as any other file system would work until you actually wrote
to it then it would go insane.
I postulated that one way to solve this would be to use LVM or MD, however
when we tried this I hit a road block in that pvcreate won't let you
pvcreate a regular old file, you need a device file, the same thing with MD.
I finally managed to get it to work without having to hand add any devices
into /dev... here's how...
For my testing I created 4 100MB files using the command: dd if=/dev/zero
of=part[1-4] bs=1024k count=100
This is what Kevin would need to do to on his flash drive...
1. Create 16, 2GB files on the flash drive named part[1-16]
2. Create loopback to file mappings using the command "losetup /dev/loop1
part1", repeat for all devices Also note, with this you could setup loopback
encryption on these devices...
If you suddenly find yourself without a loopback device issue the command in
/dev "./MAKEDEV loop" However, I think udev will probably take care of it
behind the scenes.
3. pvcreate /dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4 ...
4. vgcreate vgHACK /dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4 ...
At this point if you issue a "vgdisplay" you should see how many (PE)
physical extents you have.
5. lvcreate -n volume_name -l num_of_extends vgHACK
If you use -L you can specify 300M, etc. Also you can specify how many
stripes you want the data to be written in, which is handy if your 16
devices were on seperate disk controllers...
Also you don't have to use all the extends in one logical volume, you could
create lots of little volumes.
6. mkfs.ext3 /dev/vgHACK/volume_name
7. mount filesystem, sit back in bemusement that linux gives you the
flexibility to do such things.
Now... while were at it, if instead of LVM, if you wanted to use MD, this is
what you'd do.
If you have the lvm stuff from above, unmount the filesystem and issue a
vgremove vgHACK it'll warn about active volumes, blah, blah...
This command will take loop1,loop2,loop3,loop4 and put them into a 4 member
RAID0 with no spare.
mdadm -C /dev/md0 -l 0 -n 4 /dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4
This command will create a raid5 out of the four devices without a spare.
mdadm -C /dev/md0 -l 0 -n 4 /dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4
It'll go off and build the array, now just format and mount and you're set
to go. cat /proc/mdstat to see what it's upto.
I was thinking of other insane things that Kevin can do with his 3 32GB
flash disks.
He could create 3 logical volumes each containing 16 members and then create
an raid5 MD device using the logical volume members...
He could create 3 16 member raid0's and then create a raid 5 out of them.
He could install ZFS on top of fuse and then put all 48 devices into a
zpool...
I'll stop here, but I'm sure others have some even demented/funny ideas...
Enjoy!
Tim.

(redhat,fedora)(LONG) yum.repos.d? for local-net base RPMs
by Doug Mildram
Hi! I had imperfect luck googling the best/easiest answer to this one.
Maybe I just need a good "yum book/tutorial".
I may have solved (poorly or OK)
my "simulated challenge" (planning for an RHCE exam) which is:
Let's say I had no Internet,
but I did have RedHat RPM's on a local server,
so doing a new-install with JUST the first boot cd, then
linux askmethod (chose ftp/nfs/http, whatever the server's offering)
And did the install using network'd RPMs.
Later, say I wanna "yum install" something-else missed earlier,
without manually pointing to RPMs. (keep using yum, without Internet).
Out of the box, yum didnt adjust itself to my "askmethod" location.
Tis on the RHCE exam prep list:
"configure to update/install pkgs from remote repositories using yum or pup"
I'll attempt (poorly,toomuch...) to finetune a more specific QUESTION:
.....................How to modify the yum (config or yum.repos.d/files)
IN ORDER TO: either REPLACE ( I managed this)
or ADD TO (more intelligently)
to use a local-network source for "base RPMs"
(whatever comes on the .iso CD/DVD's , a likely RPM stash/set)
Here's one answer that might be OK in the isolated situation:
a) Comment OUT primary line in /etc/yum.repos.d/*file within [base]
(ymmv, "baseurl" or "mirrorlist" line, look for comments/fallbacks)
then b) add ONE LINE "baseurl=ftp:...", whatever the server's offering.
I'll assume ==dumb to create a NEW /etc/yum.repos.d file with [base] or [??]
Also assume there's better ways to solve this.
====== here's a comparison of a centOS 4 vs rhel 5 /etc/yum/repos.d :
CentOS release 4.5 (Final) [doug]$ pwd
/etc/yum.repos.d
[doug]$ grep \\\[ *
CentOS-Base.repo:[base]
CentOS-Base.repo:[update]
CentOS-Base.repo:[addons]
CentOS-Base.repo:[extras]
CentOS-Base.repo:[centosplus]
CentOS-Base.repo:[contrib]
CentOS-Media.repo:[c4-media]
==== centOS 5 looks the same as above/centOS4.
but RHEL 5 is quite different in yum.repos.d
below:=======RHEL 5 workstation:
$ cat /etc/redhat-release
Red Hat Enterprise Linux Client release 5.2 (Tikanga)
[doug]$ ls /etc/yum.repos.d
rhel-debuginfo.repo # ONLY ONE short FILE ,
# and it's ignored ("enabled=0") anyways.
## NOTE LACK OF visible [base], [updates], etc....
So there's some hidden magic here, neither in /etc/yum.conf.
[doug]$ cat /etc/yum.repos.d/rhel-debuginfo.repo
[rhel-debuginfo]
name=Red Hat Enterprise Linux $releasever - $basearch - Debug
baseurl=ftp://ftp.redhat.com/pub/redhat/linux/enterprise/$releasever/en/o...
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
oops, too much info. Favorite yum pointer for this topic,
or just advice welcome! thx -doug

CNR updating?
by Bill Mills-Curran
I put linspire on a laptop many months ago (better support for my
wireless card). I would have expected some kind of notification that
software updates are available for applications, but I see nothing
indicating that I should update things.
I'm using ubuntu on other systems, so I'm familiar with that update
method.
What do I do to poll for updates with CNR?
Thanks,
Bill
