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 -- Eric Martin Key fingerprint = D1C4 086E DBB5 C18E 6FDA B215 6A25 7174 A941 3B9F

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. -- I am weary of the allegiances of any politician who refers to their constituents as "consumers".

(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....

Re: [Wlug] raid1

by John Stoffel

Simeon> I'd like to set up Raid-1 on my computer. I have 2 500Gig Simeon> hds, one of which is empty, and one of which has data (that I Simeon> want to keep). I found this guide, Simeon> https://wiki.ubuntu.com/Raid (I use Ubuntu), and liked the Simeon> "super simple md" recipe, but I'm not sure how to do this so Simeon> that I don't loose data. (I searched around, but the only Simeon> thing I found required the alternate install CD, which I have Simeon> issues with.) It's pretty simple actually, and what helps is that you have an empty drive. The basic steps would be to: 1. Build an MD device onto the new drive, using RAID1, but with a drive missing. I'd make a pair of primary partitions, one of about 1gb, the other the remaining space. Use the 1GB partition for a /boot partition. 2. Then partition the new MD device (md0 say) or put LVM on top of it to make your devices. 3. Copy your data from the old non-RAID partitions onto the new ones. 4. When you're done, blow away all the old disk stuff, then add it into the RAID1 md0 device as the other half of the mirror. The KEY thing to realize here is that to make sure your system can continue to boot properly, you will need: - bootloader on both disk's MBRs - a non-RAID1 boot partition on both disks - testing, testing, testing. Good luck! John

I have more data on the 500 Gb drive than I have space on my spare 80 Gb drive...so it sounds like backing up is not an option (unless you have another idea). I might add that the drives have about 7 partitions each. Would it be possible to set up raid one partition at a time, backing up each partition b/f setup?

I'd like to set up Raid-1 on my computer. I have 2 500Gig hds, one of which is empty, and one of which has data (that I want to keep). I found this guide, https://wiki.ubuntu.com/Raid (I use Ubuntu), and liked the "super simple md" recipe, but I'm not sure how to do this so that I don't loose data. (I searched around, but the only thing I found required the alternate install CD, which I have issues with.) Any help would be appreciated. Simeon MacMillen

REMINDER: Meeting Thurs, Aug 21st, 7:00 PM

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Everybody, At this WLUG meeting, our guest speaker will be Liz Johnson, friend of long time WLUG member Greg Avedissian. The topic for this meeting will be an introduction to GIMP, the GNU Image Manipulation Program. Here are some words about the talk from Liz: ===== A paint and image editing program, GIMP is Linux's software alternative to Adobe Photoshop. Learn basic methods of working on images such as jpeg, bitmap, tiff. GIMP can import PDF documents and the Raw image formats used by many digital cameras. Restore old photos, color-corrrect, resize, crop, correct exposure, redeye, flash. Use special effects such as emboss, sharpen, smooth. color enhance, transparency, sparkle, or softglow. Create your own desktop images, icons, and logos. GIMP can help you lose 15 pounds overnight, or make you look like everyone's favorite movie star. It's open source, 100% natural, non-toxic, and free. ===== The website will be updated shortly. See ya there!

Re: [Wlug] Accessing Host Names

by kstratton＠fastmail.us

I will look into using /etc/hosts. I can not use /etc/resolv.conf since it is overwritten by DHCP and I want it that way (for now). Thank you.
