You can't mount an ISO image file read/write and manipulate it. Are you building an ISO image from a directory tree full of files, or did you get the ISO file directly from an FTP site? Usually getting the original ISO is the best way to do things, so you get an exact replica of the original CD. If you are copying a physical CD, the best way is just like this: cdrecord -v dev=/dev/sgc speed=4 /dev/scd0 assuming /dev/scd0 contains the source CD and /dev/sgc is the CD writer device. Set the speed to only as fast as the source CD drive is. If you only have one CD-ROM drive, this obviously won't work, so you would need to 'dd' the image to disk first: dd if=/dev/scd0 of=rh71apps.iso then cdrecord that file. -- Charles R.

RedHat Apps CD

by Bill Mills-Curran

I'm trying to burn a CD from the RedHat 7.1 distro. However the CD has a bunch of hardlinked files that, if the files get copied as duplicates instead of hardlinks, makes the CD too big. The mkisofs command generates copies. I'm going to try to mount the iso image file and manipulate it manually, but I don't know if this is right. Suggestions? Thanks, Bill

About 6 months ago I stumbled across an awesome GTK+ mail/news reader very similar in look to Netscape Messenger (and far superior to XFMail) called Sylpheed (http://sylpheed.good-day.net/) It'll handle as many accounts as you want, supports threading and image view through gdk-pixbuf, is extremely fast (and decently configurable), and I've never had it crash on me. Some distributions are starting to pick it up now, and it's included in Mandrake 8.1, though I usually compile myself from source. I'd suggest giving it a look if it's an X app you're looking for.

Email reader...

by Stephen C. Daukas

Well, as it turns out, the version of KMail that comes with RH 7.1 is threaded, and very different from the version included with RH 6.2. So far, a pretty good mailer...

If this is a RedHat machine, run rpm -V. Some h4x0rs know how to hack the databases, but it may still catch some nasty stuff. ccb

You can take your pick of the actual reader. I prefer pine, because, although it's not fancy, it does a lot of things right. Bill

RE: [Wlug] Vunerable Machine

by Stephen C. Daukas

OK - another is a series of product recomendation questions... Anyone have a favorite graphical threaded email reader that supports multiple POPs and/or IMAP? This, of course, excludes Netscape (can't have multiple POPs nor a mix of POP and IMAP accounts). I'm currently using the KDE mail app that comes with RedHat 6.2 (will be upgrading to RH 7.1 in about 10 minutes), but it isn't exactly stellar... You can't do much of anything while it cheks for new mail, and it isn't threaded. Regards, Steve ______________________________ Stephen C.

RE: [Wlug] Vunerable Machine

by Long, Mike

If you can determine that the machine has not been hacked then you could bring up the security holes you found to the big-wigs in the following way. The decision to use Linux was a very good one. Machine X was configured in a way that left it vulnerable to being compromised. However, because it is a Linux box and not a windows box it has not been compromised so far. The techniques for compromising a Linux server are more complex than those used to compromise a windows server. Since the tools for securing a Linux server are much more robust than those used to secure a windows server it will be virtually impossible to compromise the companies network through this server once it has been properly configured. A little spin can go a long way. :) Mike -----Original Message----- From: Marc Hughes [mailto:hughesm@tomsnyder.com] Sent: Friday, October 05, 2001 1:53 PM To: wlug(a)mail.wlug.org Subject: RE: [Wlug] Vunerable Machine On Fri, 2001-10-05 at 13:40, Keller, Tim wrote: > step 1: Change the root password Done > step 2: Remove all those "holy" services Done > step 3: Install SSH Still have to do ... getting weird library conflicts > step 4: Firewall the machine so that it only accepts SMTP traffic from the > outside world and SSH traffic from a couple of specific addresses TODO > step 5: Use a tool like tripwire to make a snapshot, wait a week, rerun it > again and see if anything changes. > Good, but still, how do I tell if it's already been rooted by 3l33t h4x0rs?
