Samba config help
by Pete Wason Oct. 30, 2008

Oct. 30, 2008

I wil PAY someone to come to my house and help me configure Samba on my CentOS server. I have three Windows machines set up with an admin user and a non-admin user. I don't really care right now if the non-admin user can access my server, I just want seamless access as admin so I can transfer stuff for my websites without using floppies or CDs. I have lots of money. No, wait, I *don't* have lots of money :) but maybe we can work something out. If I can make my server an ldap server and set up domain stuff, cool. If not, whatever works. I also have a Pegasos running MorpOS (which has its own copy of Samba), and a couple of Amiga 3000s which could either be setup with smbfs (which I had working at one point), or they could just FTP to the linux box (assuming I can get SMB access there from the Windoze side). Lot of fun to be had by all! Open to suggestions, Pete Wason???Hy Noom Publications???codevark(a)aim.com???508.865.5414

GIMP question
by Richard Klein Oct. 22, 2008

Oct. 22, 2008

It's not necessarily a Linux-specific question, but I'm creating some maps for the company Halloween party to direct kids to cubicles that have candy. I want to mark those cubicles with jack-o-lanterns. Using the GIMP, how can I use some jack-o-lantern clip-art as a stamp? It might be useful to keep the jack-o-lanterns on a separate layer in the process. -- Thanks! Rich

It's called Universal Netboot Installer and "UNetbootin allows for the installation of various Linux/BSD distributions to a partition or USB drive, so it's no different from a standard install, only it doesn't need a CD.

Mythtv Hardware
by vze284qe＠verizon.net Oct. 16, 2008

Oct. 16, 2008

Hello all, I'd like to know what Wlug'ers are recommending for mythtv hardware these days. I already have a Hauppauge PVR-350 TV capture card. I'd like to build a low-profile quiet mythtv box that I can put next to a standard TV (not hi-def). What do people recommend? What about disk space? Ideally, I'd like something about the size of the mac-mini, but I don't think I can use a mac-mini as a mythtv backend. I already have a mythbuntu box, but it's big, noisy, and not suitable for what I'm looking for. Any ideas?? -- -Chuck

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI all, I was hoping that we could talk about the upcoming Intrepid Ibex release of (K)Ubuntu. I loaded this software onto my laptop, but unfortunately, I cannot get dual monitors working, and that means the projector won't work with my laptop in its current state. I've seen a lot of bug reports and complaining about this problem, but nothing that I've tried will make it work. If/when I do get it working, I'll bring my laptop to the meeting, but it is not looking promising. Failing that, as a backup, if anybody has a laptop that is running this software, and has its output VGA port configured for 1024x768@60Hz (and tested prior to the meeting!), and would like to lead a discussion, please let me know. Otherwise, I'm open to other suggestions. Note that whatever the topic, our meeting is scheduled for Wednesday, October 15th, at 7:00 PM. See ya there! Thanks!

SSH problems
by Eric Martin Oct. 3, 2008

Oct. 3, 2008

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.

Funky LVM hack we talked about...
by Tim Keller Sept. 18, 2008

Sept. 18, 2008

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 Sept. 8, 2008

Sept. 8, 2008

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/os/… enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release oops, too much info.

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).
