[SLUG] General question Re: Securing Redhat Linux
Redhat has been known to be buggy and insecure to say the least, however it is my choice amung all distributions. My question is probably a security question that applies to all OS in general: In my case, I'm setting up a firewall that is directly exposed to the internet, and will be my frontline defense against attacks and intrusions. Provided that I - install only what I need - are aware of the functions of utils/packages that I install - do not install things that can be used against me eg. compilers, sudo, screen, debugfs, dd etc. - do not install any irrelevant servers/daemons eg. httpd, ftpd, named, rpc*d etc. - keep my packages updated stable - securing any services at the application level eg. customising kernel, xinetd, /etc/security/* etc. - monitor and apply errata (redhat.com/errata/) - monitor all logs - spend some time monitoring security advisories - use network monitoring, auditing, intrusion tools eg. snort, tripwire, user space plugins for iptables - physically isolate machines and services through better network topology/structure with security in mind I think any distribution can be ironclad. The difference then would be the effort required to secure a box OS. So provided that I stick to the fundamental security concepts, am I wasting my time with Redhat compared to Debian or Slackware etc ? There're a lot of other little things that I've come to be aware of over the years eg. mount (ro) /, find / -perms +444 etc etc. I'm reading some security guides, Redhat 8.0 has an Official Red Hat Linux Security Guide (http://www.redhat.com/docs/manuals/linux) and other Redhat related security guides can be found at linuxdoc.org. Does anybody have further advice/suggestions on securing a Redhat box ? - don't use computers maybe ? :) I'm looking forward to having a less embarassing setup, and taking better security measures this time around. -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

If you spend enough time on it you can convince yourself that any box is secure. Secure systems is one area where debian excels though. Debian packaging policy means that old, reliable software is used in favour of newer, possibly more functional, but possibly also less secure software. If nothing else debian packages are much more a known quantity than other distributions (debian stable, not unstable et al). Debian maintainers also do helpful things like disabling the no-encryption option on ssh. They also had that bug fix for ssh out before anyone else (I don't even know if that made its way into redhat etc - I assume it did but no-one made the same fuss about it that debian did) You theoretically can make redhat as secure as debian, but I would argue that your time would be better spent on more important aspects of system security. I like redhat and its bretheren, but I don't use it on servers. btw - you wanna be careful with tripwire et al. What happens when someone hacks your box and replaces the tripwire executable with one that sends an email at the alotted time intervals reporting that everything is ok? It's better than nothing, but don't rely on it. HTH James. -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
Re: [SLUG] General question Re: Securing Redhat Linux
I have a tendency to agree with what you have there. This may be only my thoughts and someone can counter argue this point. I do install compilers on to my firewall, in case I want to compile a package mind you I never install any servers, especially either telnetd or sshd, on my firewall. If I want to make a mod to my firewall I have to do it locally. Isolate machines through topologies is excellent idea, you don't want to mix live or potentially vulnerable servers with workstations. So you will have a DMZ where you will house your servers that can access the Internet, and a LAN network which will be completely seperate to the DMZ. Even though I have 6 machines at home I have broken my network environment into DMZ, and LAN. My machines on the LAN can only access services I what them to access on the DMZ, My DMZ can only access DNZ, Web, mail, ssh services on the internet. My LAN uses NAT to access internet protocols. A Distro is a Distro, some have more issues than others but if you have a look at most of redhat issues to date most of the problems exist if the user already has access to the box and wants to elevate their privileges. Provided that I - install only what I need - are aware of the functions of utils/packages that I install - do not install things that can be used against me eg. compilers, sudo, screen, debugfs, dd etc. - do not install any irrelevant servers/daemons eg. httpd, ftpd, named, rpc*d etc. - keep my packages updated stable - securing any services at the application level eg. customising kernel, xinetd, /etc/security/* etc. - monitor and apply errata (redhat.com/errata/) - monitor all logs - spend some time monitoring security advisories - use network monitoring, auditing, intrusion tools eg. snort, tripwire, user space plugins for iptables - physically isolate machines and services through better network topology/structure with security in mind I think any distribution can be ironclad.

Using a crossover cable I can successfully access the Smoothwall box from my K6 PC running Mandrake 9.0. (uses a Dlink DFE 530TX rev A nic) Trying the same thing from my K7 box (modem attached, setup and working), also with Mandrake 9.0, I can successfully ping the Smoothwall box from a terminal, both as Root and as User. However, when I try to access the Smoothwall box via a browser (Konqueror, Galeon or Opera ) I get an error message, either network problem, connection refused or could not connect, depending on the browser. On this box Mandrake shows the Lan Config as eth0 192.168.1.3 dhcp via rhine up (DLink DFE 530TX+ rev D nic). I have tried connecting with Shorewall, privoxy and the modem on and off in all combos, ensuring that I reset the browser proxy settings accordingly, with the same result. Am I correct in thinking that the problem stems from having the external modem connected and installed on the K7 box whilst also having this box connected to the Smoothwall box? (ie Mandrake is set to use the Modem for internet connection, but the Nic for Lan connection.) If so, is there a fix for this, preferably without having to remove the modem (I also run Win XP on the K7 and can't get the DLink card installed under same - no apparent driver on DLink site for XP). Once I get the nic installed under XP I'll permanently attach modem to Smoothwall box, and update Mandrake settings. Thanks in advance for any help or suggestions.

Nope, but all it said was a repeated message about Trident, which with
no date or time isn't that helpful.
What I now believe is/was the problem is the RedHat Upate agent. All the
crashes occurred whilst this was running, which was most of the time as
I was trying to update the machine (still am).
As the update agent turns out to be a rather poor ftp program, I've
reverted to using wget off the Aarnet mirror to download all the rpms,
then use update agent to install them. So long as most rpms are put into
/var/spool/up2date, the RH update agent recognises them and installs
them.
For some reason this doesn't happen with some, i.e. kernel ones can have
problems, which is back to playing Rusiian roulette.
.
This is the third day without using the RH update agent for retrieval,
so I'm fairly sure that was the problem. (Must remember to bump the FSB
back up to 133Mhz to get full grunt again).

It's my understanding (which could be quite wrong) that a computing grid is a much larger thing than a cluster multiple clusters can participate in a grid; and a grid can be heterogenous. When you're writing code for a cluster, you use OpenMPI or something. I don't think that MPI will work over a grid --- a grid is more a way to distribute jobs to clusters or machines within the grid (like NQS but bigger). See http://www.gridcomputing.com for more details. However, this leads to another question: Does the Grid Engine implement a cluster or a grid? SETI@home is an example of a grid computation.

[SLUG] New Woody Install not finding proxy server
Dear List, I have just downloaded and installed Woody on a box via 4 floppies and a network install through a proxy. After restarting the new systems I can not get any updates from Debian.org. It is asking for a format of http://proxy.user.host:port . The proxy server is 192.168.0.1:6588 and the client box is 192.168.0.10 Why should there be a problem after down loading a minimal Woody install of around 25 Megs? The new box remembered the proxy settings from the download. I have looked on the Debian website and can not find anything. It is obviously a simple thing but can not find the answer. Merry Christmas to all on the list.

[SLUG] gnump3d experiences
Hi, I just install gnump3d onto a pentium 90 at work which a friend and I use for testing stuff out, as well as allowing him to learn a bit more about debian. Anyways, I must say gnump3d is great. Its nice being able to select mp3 songs that are stored on this machine and then played over the lan to our winamp clients. Highly recommend it to anyone wanting to do something similar. All I need now is to buy a larger hard drive for home and put my songs onto it via samba, and setup a similar thing.

I've had similar problems with rsync over many different machines, over rsh, ssh, solaris, hpux, linux, with no apparent cause or resolution except by waving around a rubber chicken. Search through the rsync mailing list archives and you'll see many references to it, with the occasional fix with the comment 'yeah we've got it THIS time' I think it must be something fundamental to the rsync protocol which is broken.

RE: [SLUG] Rsync problem
The only problems I've had were with getting MacOS9 files off a MacOSX system transferred to a Linux system. I ended up doing it manually in the OS9 application and using ftp to transfer the stuff across. Other things to look for: - time/date synchronisation on both machines - files which are being opened and updated while the rsync is progressing. I suspect the file seeks on rsync might be relying on the opened file being fairly static. For short files, it should not be an issue, but for longer ones, strange things might happen if the file gets written by another process. Cheers, Jill. -- Jill Rowling, System Administrator Eng.

Re: [SLUG] Learning about security.
Hi Steve, Common sense is the simplest and most overlooked form of security. HOWTO ones, what mechanisms might someone have for getting in, especially if I am running server programs on that same machine? Learn about the ports that the services use, ie POP 110, SMTP 25 etc. keep the ports closed on the services that you are not using. Can someone spoof the interface? I wouldn't think so (but also wouldn't know!) Or can they spoof an established connection? Spoof or sniff? Spoofing is where steals an IP, yours or anyone elses to get access, sniff is when someone evesdrops on you. If you are worried about people sniffing, use data encryption SSL etc. Dont use Telnet, use SSH Also, can anyone recommend any good 'across the board' security books,i.e covering the other major OS(es) as well? Typical attacks, how to avoid them and system design/implementation considerations? "Hacking Exposed" has been touted as one option. Opinions? I dont really think that having a vast knowledge of specific attacks can help you very much. The three things to remember are: Proper configuration (ie only run what you use) Proper policy Keep all your software up to date! Best online info: www.CERT.org Good book: Security Complete (Sybex) it covers most OSs and is very reasonably priced $40 luck, ~dec Steve Downing wrote: I'd like to expand on my security skills, it's definately an important topic. One quick question, if my iptables rules are like rusty's Netfilter HOWTO ones, what mechanisms might someone have for getting in, especially if I am running server programs on that same machine? In a nutshell those rules are: Drop on the ppp0 interface, unless the packet is flagged as a established or related connection. Accept new connections on any interface but ppp0.

Re: [SLUG] OpenMosix vs Grid engine
quote who=Rowling, Jill Anyone know what is the difference between Open Mosix clustering vs the Grid Engine project http://gridengine.sunsource.net/ as far as the end user's application software is concerned? It's essentially the difference between 'single-image clustering' and 'multiple-image' (or even heterogeneous) clustering. With OpenMosix, everything is handled at the kernel level, allowing you to run and migrate any process [1] within the cluster. There are no special tools to run process on the cluster, because you're already a member of it (though there are utilities to say 'run this process on that node', etc). The Grid Computing stuff that Sun ships, from what I've worked out, is not as cool. :-) You must run processes with the q* utilities, it works with jobs and queues, handles multiple architectures, etc. So, OpenMosix acts like a big fat SMP box that you can just keep adding processors to (which prefers processes to threads), whereas Sun's Grid computing stuff is basically just a job/queue-driven processing farm with the ability to grok multiple archs as part of the cluster. Two random good sources of info: http://gridengine.sunsource.net/project/gridengine/howto/howto.html http://sourceforge.net/docman/display_doc.php?docid=9562group_id=46729 - Jeff [1] Except when the process uses stuff that OpenMosix doesn't support yet, like mmap, etc. -- 'Cause remember, smug is beautiful. - Zachary Beane -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
RE: [SLUG] OpenMosix vs Grid engine
Hi Jeff, Thanks for that. What I'm trying to do is speed up some programs we use at work. Some of them take a week to run on a PC (er, maths and statistics...:) and there are a number of machines around the place that are idle at night. I was looking for something maybe not as inefficient as SETI@home that could be run on a variety of OSs: Linux, IRIX, Solaris, WinNT preferably without too much pain but preferably controlled from one node (ie the programmer's work area). It's important that the job run at low priority because the various machines have other tasks that must be done at certain times, and this application is supposed to only run when the machine is otherwise idle.
