Help! Basic Linux Introduction?
All, I just got tasked with providing (by this afternoon!) a short primer on linux, preferably RH 9. I need something that a group of MIS Windows folks can read in two evenings, such that I can then sit them down in front of RH 9 boxes and show them how to administer the basics. I've found the RH 9 manuals on their site, and if I have to I will resort to printing off various sections of them and putting them together, but I was hoping for something a bit more coherent. Basically, it should cover the basic concepts and such. I'm also looking at tldp.org. Anybody have something like this laying around? Thanks!

Does the same apply to RH 7.3? Yes, this is a *kernel* issue, so whatever version of RH you're using, if you'v updated teh kernel, you can be susceptible. In fact, in comment #15, another user mentions that they started seeing this issue in RH 7.3 after they also updated their kernel. > Second, what > exactly do these bdflush figures represent, and how does the recommended > edit change the behavior of the system.

As I understand it, the bdflush parameters deal with when the kernel flushes cache to disk and how it deals with virtual memory. I haven't dug deeply into it, as the options I detailed in my previous post have worked just dandy on our web server. Nevertheless, a google on "bdflush parameters" pulled up many hits, including: http://www.faqs.org/docs/securing/chap6sec68.html https://listman.redhat.com/archives/ext3-users/2003-May/msg00035.html https://listman.redhat.com/archives/ext3-users/2002-November/msg00073.html and many others.

Okay, I know, I've replied to my own post twice now, but I wanted to get this into the archives. The process that I detailed above works, with one exception. In step #4 above, the cp -r does not copy hidden files. This means that you have to manually copy the /.discinfo from RH9 CD1 to the temporary directory before making the iso image. Otherwise it doesn't install. Ben -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list

kickstart install from a RH9 DVD via USB?
All, We need to deploy RH9 to a few places where outside network access is a no-go. So, here's what I was thinking, and I'd sure appreciate any help/suggestions I could get. Basically, I want to create a bootable DVD that has all three of the RH9 CD's as well as all of the up2date packages that are current to the install.

virus and a worm. My response was to his assertion that you didn't need
"virus" protection on a linux machine.
In my experience, complacency leads inevitably to disaster.

Wow, Hal, guess've just slept the last year or so. Ever heard of Slapper? At one point it had infected at least 13,000 distinct machines: http://www.cert.org/advisories/CA-2002-27.html http://www.f-secure.com/slapper/ I didn't have time to dig any deeper for other worms, but I'm sure that you can find more in Google.

Re: Open TCP & UDP Ports

Port scans run from the same *machine* can be misleading, as many ports that are open on the localhost are blocked by iptables (the line with " -i lo -j ACCEPT" accepts any input from the local machine). In other words, the services shown by "netstat -tap" as listening to ports are often blocked by iptables so that other hosts may not access them. So, nmap scans from other hosts on the same subnet won't be any different from nmap scans from any other host on the internet, unless there is another firewall blocking the path.

Any ideas on how to set this up? You could set up open relaying, but then every spammer in the world would use your server, and you would end up on every anti-spammer's black list. :) Seriously, check out SMTP AUTH. I believe that there's a PAM module for it somewhere that will allow your users to authenticate against user accounts on your server, and once that is done they can send email.

This could either be because the daemon is no longer accepting local connections, or possibly your firewall settings have changed disallowing local connections. You can check your firewall settings via: ipchains -L and you can check to ensure that your sendmail is listening for traffic via: netstat -tap | grep smtp Show us the output of those two commands.

Otto, I'm sorry, but you have absolutely no idea as to how ethernet works in a *switched* environment. You are describing a LAN that is on a hub. In that case, you are correct with all of your above comment. On the other hand, in a situation where all of the hosts are connected to a *switch*, instead of a hub, then each "segment" consists of exactly two devices: the host and the switch port. In that case, the chance for collision is greatly reduced. The reason for this is simple: If host-a transmits a packet while connected to a hub, then all other hosts connected to that hub will see the packet, whether or not it is intended for them. If host-a transmits a packet while connected to a switch, then something entirely different happens. The switch looks at the packet and decides where it is to go. If it is a multicast or broadcast packet, then most or all of the other hosts on the switch will see it (I won't go into those rules, it's beyond the scope of this particular discussion.) If, on the other hand, it is a *unicast* packet, and the destination host is on the switch, then the switch will only transmit it on the port to which that destination host is connected. If the host is not connected to the switch, then it will send it on it's "uplink" port, depending upon configuration. Now, what this means is that any host that is connected to a switch will only see broadcast traffic, multicast traffic to which it is subscribed, or unicast traffic that is addressed to it. This sharply decreases the number of packets that the host's ethernet card will see as inbound, which will thereby reduce the number of collisions during transmission and subsequently increase the perceived bandwidth. At that point the bottleneck becomes the switch's backplane capabilities, not collisions. Switched ethernet is vastly superior to ethernet on a hub, and has become very cheap. It is now easily in reach for most organizations, including the home office. Ben -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list

This is not quite always the case. Ethernet's CSMA/CD (Carrier Sense Multiple Access with Collision Detection) was invented during a time when a hub or bus were the primary method of connection. Collision was indeed a problem then, and keeping the LAN small was a way to ensure network performance. However, these days, switches are much cheaper and are easily within the reach of most organizations. If your users are hooked up to a switch instead of a hub, you can ignore the "collisions problem", as it no longer exists. At that point, the limiting factors are the speed/RAM of the gateway and the speed/RAM of the switch.

Multi-install question
I have a multi-boot test system. It currently has one drive with both XP and Shrike installed. I installed XP first, so I'm using Grub as the boot loader. I've installed a second drive and am about to install Win2K on it. Now, I know that this is going to break my install and that I'm going to have to do something to fix it, and I just wanted to make sure that I understand what's about to happen. The win2k install will leave the hda partition table alone, but will over-write hda's MBR, telling it to point to the boot sector on hdb (where I'll be installing win2k), correct? So, all I should have to do is: a) backup hda's MBR (dd if=/dev/hda of=/dev/fd0 bs=512 count=1) b) install win2k on hdb c) restore hda's MBR (dd if=/dev/fd0 of=/dev/hda bs=512 count=1) d) manually edit /boot/grub/grub.conf and add an entry for hdb Does this sound correct?

If your central server is linux, then you could load tight-vnc (http://www.tightvnc.org) on it.

I've written a very short howto on this. It assumes that you've installed something called "tight-vnc" on your system (http://www.tightvnc.org) on your system.

Good! An interest in how things work is always a good beginning. :) One good place to start is: http://www.redhat.com/docs/manuals/linux/ Another is: http://www.tldp.org In your particular case, you're running into the default security setup for mail transport agents (MTA) like sendmail and postfix in RH. By default, RH comes configured to be able to send email but not receive it. This is to help keep open relays off of the internet. First you'll need to ensure that you open port 25 on your firewall. Next you should look at: http://www.redhat.com/support/resources/howto/RH-postfix-HOWTO/x118.html It's long, but it goes through all of the main.cf configuration file. It should help you out.

Re: Plea to Linux Users

There are times and places where each approach has it's merits. In my case, where I am a member of a military CERT, we have to be absolutely sure that our systems are secure. This means that we have a rather involved response protocol, and part of it is retaining evidence, as Jason alluded to. You also have to remember that we are forbidden from attempting to "trap" a hacker, since we are not law-enforcement. So, basically, we will shut down the system and disconnect it from a network. Then we'll make a full image of the drive, when possible, for forensic analysis. Then we'll boot from a known-good CD to run some checks, etc. When you are dealing with national security, it's not exactly "small/home office" applications. I agree that it is labor intensive. But if you are going to do security, the Department of Defense tells us military CERTS to "do it right or get the hell out of the way so somebody else can".

I should have checked to see if it was, in fact a binary. Your pointing that out to me caused me to look at the script, and it gave me another place to look, to wit: /usr/lib/perl5/site_perl/5.6.1/Mail/SpamAssassin Unfortunately, that didn't work either. *sigh* I tried rpm -q --filesbypkg perl-Mail-SpamAssassin which shows a bunch of files .pm files in /usr/lib/perl5/site_perl/5.6.1/Mail/SpamAssassin/ I tried rpm -q --filesbypkg spamassassin but it was the /usr/bin/spam* scripts and some man files. At this point I'm afraid I'm going to have to give up. I don't have the time to mess with it. Thanks for all of your help, though!

Um...Jason...the CERT training that I went to stated (though I have not verified it externally) that it is still possible to fool chkrootkit if you are running it in a "compromised environment". We were taught that the best way to go is to run it from a "clean" medium, such as knoppix, to ensure that any of the binaries or LKM's aren't spoofing you. I know, you specifically stated that you should use good binaries...but this is easier and (AFAIK) foolproof...

I'm not sure who the MailScanner is running as, so I don't know about the path, but I did try setting the binary path in the MailScanner.conf file: SpamAssassin Install Prefix = /usr/bin And no dice.

I'd say don't download and compile chrootkit. Instead, download the knoppix security tools distribution (http://www.knoppix-std.org/), burn it to a CD, then boot from it and *then* run chrootkit, which is on the CD. This way you will *ABSOLUTELY KNOW* that you are running a safe version of chrootkit that will tell you whether or not you've been compromised.

I hope that RH isn't shooting themselves in the foot with this. I think I understand the rationale, but it was the close branding between Red Hat Linux and Red Hat Enterprise Linux that convinced my boss to go ahead and purchase RHEL Advanced Server. I'd already deployed a couple of RH 9 boxes and showed him what RH was capable of, and when he found out that there was a commercial version that had enterprise support, he decided to purchase. He viewed RHL as the "entry level" and RHAS as the "professional/commercial level". I don't think that he's anywhere near alone in that view. I'm afraid that by making this move, RH may do two things: 1) Fedora won't be as popular with the newbies, since it won't have the famous "Red Hat" name, and the distribution will lose newcomers to Suse, Mandrake, and Debian. 2) RHEL will lose market share because they won't have the hordes of people trying/using RHL at home or for small project who then look to upgrade to RHEL.

Okay, now for the big question: RHCE? As I understand it, the current RHCE exam is based on RH 8.0. If RedHat is now dropping the free version of RedHat in favor of the Fedora Project, is the RHCE going to be splintered? Or are they going to change the test to be based on the Enterprise Linux?

Okay, 2 questions:
1) do you have any other machines on the network that *are* able to
receive dhcp leases?
2) Have you tried it *without* the MAC address specification?
Typically when I'm trying a new server, I try it with the simple stuff
before I start using the esoteric settings (like MAC address
restrictions).

Vipul's Razor and SpamAssassin?
Okay, I have MailScanner working with f-prot, and BOY is it catching all of those Swen.A virii! However, I can't seem to tell whether or not the Vipul's Razor that I installed yesterday is working. I'm running SpamAssassin 2.50, and it seems to be working fine. I've added 'use_razor2 1' to /etc/mail/spamassassin/local.cf and restarted. If I run razor-check against a spam that I've saved to a separate file, it is identified. However, if I put the message through the spamc client, while I get a bunch of other rules, it doesn't show any rule checks for razor. Any ideas would be appreciated!

OT: MailScanner question
Okay, I know that this is Off Topic, but if the answer is easy, I'd rather not have to join another list. If it's involved and there's not an easy-recipe web site (I haven't found one after quite a bit of search) then I'll go join the mailscanner list. I've dedicated this weekend to making my mail server a safer place to live. :) I finished getting Vipul's Razor installed (and am now waiting for a spam to come it to see if spamd is auto-recognizing it as advertized). Now I'm trying to install anti-virus. I've got f-prot working from the command line, and have been reading the docs for MailScanner to try and get it installed. They seem to have a bunch of stuff related to spam-assassin, but I have that running via my procmail. Do I have to stop using spam-assassin via procmail and start using it in Mail-Scanner, or is it an optional thing? Thanks!

Just because the host resolves does *not* mean that it is actually serving the ntpd service. You can tell if it is or not (I think, since I can't find a man entry) by typing "ntpq ". When I tried that on the time.nist.gov server, I didn't get anything. Ditto when I tried ntp.tuxfamily.net. However, when I tried it against clock.redhat.com, I got a response. Try changing your ntp.conf to clock.redhat.com. Also, check that ntp is open on your iptables. Try "iptables -L". You should see a couple of lines something like: ACCEPT udp -- clock.redhat.com anywhere udp spt:ntp dpt:ntp ACCEPT udp -- clock.redhat.com anywhere udp spt:ntp dpt:ntp The ntp daemon is supposed to automatically open the iptables firewall, but you might need to restart the service (service ntpd restart) to do it.

Check your log messages again. Your post showed that you're getting an "invalid host" error when trying to find time.nist.gov.

This is true, but there is one problem in the disaster recovery universe that it does not resolve: offsite storage. If your backups are routinely kept in the same place as your servers, and you have a catastrophic event, you will have lost your data forever.

I manually copied all the sites over, and setup apache. My > question is, I'd like to set up a cron job to once a week copy the > contents of folders on the windows system and replace the content in the > same folders on the redhat server. Is that possible? The easiest solution would probably be the following: Go to http://www.chiark.greenend.org.uk/~sgtatham/putty/ and get the pscp.exe package. It is a secure copy client for windows, and it is strictly command-line. You should be able to write a batch file to call it and copy your files to the redhat box. NOTE: You'll have to authenticate from the windows box to the redhat box. This means either that you will have to store the redhat account password in the windows box or a certificate. Storing the password is dangerous, because if somebody compromises your windows box, they'll have your redhat password. However, I do not know how to do the stored certificate thing, so maybe somebody else here can help with that one. Anyway, once you have written the batch file, use the windows "AT" command to set it up to run at a specific time each week, and you're done. To implement a bit more safety, I'd set up a non-priviledged account that was chrooted to a directory in /tmp and use that to copy the files over. Then have a cron job on the redhat box that will check the next day for any files in that directory and copy them to the appropriate place on the redhat server. You can still get hacked if somebody compromises your windows box, but it would be a bit more difficult.

Then, on the XP box, install WinSCP (http://winscp.sourceforge.net/eng/), which will allow you to copy files back and forth in a secure yet easy way. If you are on the linux box and want to access files on the XP box, you'll probably use smbclient, though I don't have any experience in that area.
