Changing the port used by sshd stops the completely clueless script kiddies, since they don't even bother looking at anything other than port 22. Putting it way up high, among the ephemeral ports, will slow down the slightly more clueful who perform nmap scans, since nmap only scans around 1500 ports by default, and if sshd isn't running on one of those, they won't spot it. However, it won't deter the intelligent or curious attacker; these guys will scan all ports (slowly, so you may not even notice them) and they will use banner enumeration to identify the services, rather than assuming. Moving sshd to a non-standard port is one of the worst examples of relying on security by obscurity. Its only advantage is that it cuts out some noise in the logs, but proper precautions do that as well, without lulling you into a false sense of security. Rate limiting, combined with enforcement of really strong passwords, or even better, public/private key authentication, is real security. A useful additional layer of defence, if you want it, is a daemon that will watch for port scans on the simple services ports and immediately insert a firewall rule to block that source - such as the old PortSentry, if you can find it, or some more modern equivalent. Of course, this won't do much to defend against some types of stealthy scans, such as idle time scans.

OT: Making BT/Yahoo account accessible to plain router

My daughter has a BT account, with a BT supplied single-port router. I'd like to replace it with a standard router, but the settings appear to be totally hidden. If anyone reading uses BT, could you please tell me where to find the info? Maybe off-list, to save bandwidth for others/ Thanks Anne

I wrote a Perl daemon that I use to tail service log files. Initially it was a Postfix log scanner that looked for unknown address attempts, relay attempts, and honey pot email addresses that I embedded in my web pages. When any of these hits turned up in the mail log, the senders IP was added to the iptables rules. My goal was to cut down on spam. It helped some, but not enough to call it a complete success. But it's very modular. I started having some problems with brute force ftp attacks. Very annoying, kept filling up the log files (and my log partition) with chaff. So I wrote another module for my daemon to scan the ftp logs as well and firewall any ip that failed to log in after 10 tries (a 3 hour time out). This was very successful and now ftp crack attacks are a thing of the past. I've never had ssh problems. My ssh port rules limited it to a few known IP addresses that I may need remote access from. But my Perl daemon could be easily expanded with another module to scan for ssh attacks. Provided you've got some Perl experience and time to hack (I'm hog tied for the next while).

Sendmail conf
by Joseph L. Casale 23 Jul '08

23 Jul '08

A long time ago someone helped me with setting up sendmail to simply queue and relay mail. They suggested: 1) edit /etc/sysconfig/sendmail and set "DAEMON=no" 2) edit /etc/mail/submit.mc and set FEATURE(`msp', `[IP.of.relayhost]')dnl Given the sendmail-cf RPM is already installed a "service sendmail restart" is enough to a light, direct submitting sendmail setup. How does one rewrite all mail to one specific address so it can be filtered by a user that receives all mail for this host? Can there be a rule in place with the above config? Hopefully that is just as easy in sendmail as it is postfix! Thanks! jlc

This is why I strongly recommend the use of ssh-agent (or Pageant for those with a Windows desktop) as a mechanism for minimising the inconvenience of constant prompting for a strong key passphrase. Of course, this has to be coupled with awareness of the need to lock the workstation or unload the keys when leaving the desk. The other piece of the puzzle is agent forwarding, so that I only need to keep a private key on my workstation, even when logging in to a gateway machine and then to a server beyond it. They private key file is always under my local physical control - in fact, the truly paranoid can keep their private keys on a USB device or a smartcard. Using this approach, I can sit at my university office desk, provide a passphrase once when loading a key into the ssh agent, and then connect through firewalls to machines in my home office, with no further prompting or inconvenience and very low probability of the private key being compromised.

Printer recommendations

Since my old Epson C86 has finally managed to clog up the print heads, I'm in the market for a replacement. I'd like to know what the people on this list are using for printers that are currently available, since we are using versions of CUPS and foomatic that are frozen, and any other issues or "gotchas" that you are aware of. For the replacement printer, I'm considering a color laser printer instead of the inkjets that I've been using, and I'm dithering back and forth over the question of direct-connect or networked printer. Suggestions, warnings, and horror stories are welcome. Thanks in advance. -- Ron Loftin reloftin(a)twcny.rr.com "God, root, what is difference ?" Piter from UserFriendly

That way the application will be able to write its logs, but would not be able to change permissions on the directory. -- Bowie

perl module to parse httpd log on C5
by Mark Pryor 22 Jul '08

22 Jul '08

hello, Looking for alternative ideas to parse the combined Apache log: /var/log/httpd/access_log (is how I named it) What I've tried so far is a CPAN search, which pointed me to a recently created module called ApacheLog::Parser >From the C5 shell, I used something like this (heavily refined from how I started) ---------- sh script --------- #rpm --import http://download.fedora.redhat.com/pub/epel/RPM-GPG-KEY-EPEL yum install ncftp --disablerepo=\* --enablerepo=epel yum -y install perl-Test-Pod \ perl-YAML \ perl-Test-Pod-Coverage \ perl-Class-Accessor \ perl-IPC-Run \ perl-Time-modules \ perl-DateTime \ perl-Date-Simple perl -MCPAN -e 'install Class::Accessor::Classy' perl -MCPAN -e 'install Time::Piece' perl -MCPAN -e 'install Date::Piece' perl -MCPAN -e 'install File::Fu' # yum install perl-IPC-Run3 perl -MCPAN -e 'install Getopt::Helpful' perl -MCPAN -e 'install ApacheLog::Parser' ------------------ end snip ----------- the above worked on a fresh install of C5.2 with a LAMP setup. CPAN asked for ncftp in its setup. I must have tried 50-60 commands before I settled on the abbreviated version above. As an exercise, I took a shot at using cpan2rpm to package the tar.gz's into RPM's the resulting RPM's are here: http://www.tlviewer.org/fostats they are signed with my RPM-GPG key http://www.tlviewer.org/centos/RPM-GPG-KEY-mpryor.txt -- Mark

by Sam Drinkard 22 Jul '08

22 Jul '08

I've apparently gotten myself into somewhat of a bind. I've been trying to exclude various packages from the different repos, and while I *think* I've gotten a working configuration again, it it still pulling stuff in that I have excluded I think in the right repos, but things I have no use for whatsoever. Items like kernel-hugemem-devel, kernel-hugemem, and anything involving kernel development. I run a stock kernel and am not doing any building of any kind at this point. The machine is an i-686 machine, and a single processor. I'd be very much appreciative if someone could send me,, or post a proper repo config that points to the various exclude lines to get rid of some of the unnecessary files. It's taken me about 2 hours of modifying stuff to finally get a yum repo config to make it all the way thru. Any type of help here would be great! Thanking you in advance, Sam

recommended repo for php 5.2.3 +
by dnk 22 Jul '08

22 Jul '08

Good day all, I have been searching on google for the recommended repo for php 5.2.3 + for centos... I saw at one point it was in the testing repo, but was pulled due to no one testing it. Is there a recommended repo that people feel is safe for a CentOS 5.x to get php 5.23 + ? I know i can compile and install, but i like to keep as "vanilla" as possible. Thanks in advance. Dustin

by mcclnx mcc 22 Jul '08

22 Jul '08

we are migrated CENTOS from 4.X to 5.2 on seperate DELL servers. For printer definition migrate on CENTOS 4.X , we can use following command: printconf-tui --Ximport < printers.xml I can not find "printconf-tui" command on CENTOS 5.2. Does anyone know how to migrate printer configuration on CENTOS 5.2?

Kernels From CentOS Plus
by Bob Taylor 22 Jul '08

22 Jul '08

I found I have the following kernels installed last night: kernel-devel-2.6.18-53.1.21.el5 kernel-headers-2.6.18-92.1.6.el5.centos.plus kernel-devel-2.6.18-92.1.6.el5 kernel-2.6.18-53.1.21.el5 kernel-2.6.18-92.1.6.el5.centos.plus kernel-2.6.18-92.1.6.el5 kernel-devel-2.6.18-92.1.6.el5.centos.plus Evidently I have a wrong priority for centos plus? I have the priority in every item in CentOS-base.repo set to 1. I *think* the kernel in centos plus was a special one. Thanks, Bob -- Bob Taylor

Every day I see this in chkrootkit's log - Checking `crontab'... Warning: crontab for nobody found, possible Lupper.Worm... not infected I know I met this once before, but I can't remember whether there is any cure for it. It doesn't seem possible to remove nobody in kcron, and there are no tasks set. What could/should I do about it? Anne

Nautilus Behavior
by Michael A. Peters 21 Jul '08

21 Jul '08

In CentOS 5.1 - if I had a folder open on my desktop on one worskspace screen and I was in another workspace, and I double clicked the folder icon on my desktop, it would bring the open folder to my current workspace. In CentOS 5.2 it does not do that. I can't find a setting to change the behavior to what I like. Any suggestions?

OT - Windows slowdown?
by MHR 21 Jul '08

21 Jul '08

I know this isn't the right forum for this (do I ever!), but you-all know so much about everything I thought I'd ask. About two months ago I resurrected my daughter's Compaq laptop (cracked screen - replaced it) and ran an update on it. It's running Windows XP, SP1 (I think), but since the update it has run about 1/3 as fast as it used to. Does anyone know if there was a WXP update that killed performance on laptops? None of my other XP installs, SP1 or SP2, suffers from this. (Actually, I should say "their other" 'cuz I don't use Windows unless I can't avoid it, and then I try to do it on my WXP VM where it's still relatively safe.) Thanks. mhr

moving software RAIDed disks to other machine
by Kai Schaetzl 21 Jul '08

21 Jul '08

I just replaced two md-raided (RAID1) disks with bigger ones and decided to check out how far I get with them when I put them in another machine. The kernel boots and then panics when it wants to mount the root filesystem on the disk. md: Autodetecting RAID arrays md: autorun md: autorun DONE < not sure if this means it was successful or failed, I rather think it failed because it doesn't list any md devices? > Creating root device Mounting root filesystem EXT3-fs: unable to read superblock I pxe-booted in rescue mode. Interestingly, the rescue mode detects and mounts the RAID partitions just fine and mdadm sees them all as healthy. It mounts them under /tmp/md0 and /tmp/md1. Shouldn't the installed system be able to do the same, mount under /dev/md0 and /dev/md1 and then find root on /dev/md1 as told by grub.conf? Or could it be that the installed system also mounts them under /tmp? I'm not sure how I can troubleshoot this.

Cannot boot from DVD on an Intel Svr to install CentOS 5.2
by saltorres＠lvcoxmail.com 21 Jul '08

21 Jul '08

Hi, I'm new to CentOS and I want to install CentOS 5.2 on an intel computer to use it as a server. I downloaded the CentOS 5.2 DVD iso i386 and did the md5sum, burned the DVD and everything was Ok but when I try to boot the server with the DVD, it simply does nto boot, like if nothing were in the DVD drive. I tried with a Vista DVD and it boots. It can even boot from the LiveCD. Have anybody seen this behavior and how to solve it? I'm using Free Create/Burn ISO from NBXSOFT and I believe this is not the problem because with this software I created the LiveCD. I'm working on a Vista Ultimate computer to download, checksum and burn the DVD. Thanks

Exploit 'in the wild' for Trixbox
by Nigel Kendrick 21 Jul '08

21 Jul '08

Just in case anyone else needs to know - there's an exploit 'in the wild' for Trixbox (which is CentOS based) that allows malicious code to be installed on a server. I discovered that one of my Trixbox servers was running 3 instances of a perl-based IRC botnet process called httpdse and this was pegging the CPU at 100%. Notes, comments, removal instructions, patches etc. here: http://trixbox.org/forums/trixbox-forums/open-discussion/critical-remote-roo t-exploit-trixbox-wild Guess that teaches me not to open the Trixbox Web interface to the world.

Howto: Java Plugin for Firefox 3.0.1?
by James B. Byrne 19 Jul '08

19 Jul '08

Can anyone here give me the magic decoder ring recipe for getting jre "plugged" into Firefox 3.0.1? The plugins directory is gone and the Firefox FAQ regarding this issue cryptically mentions that plugin support has been dropped. It then points one to a early adopter SUN jre1.6-10 page that has innumerable dependencies which my version of CentOS-5.2 does not meet. Firefox 3.0.0 had a plugins directory and it did support the logical link plugin: ls -s libjavaplugin_oji.so /usr/java/default/plugin/i386/ns7/libjavaplugin_oji.so I have no clue how to get java to work in FF3.0.1 at the moment. Any help would be appreciated. -- *** E-Mail is NOT a SECURE channel *** James B.

Semi Off Topic My searching hasn't found what I consider superior info, and we are wondering from others experience on this list...

How to examine crash dump of Centos Kernel
by Nataraj 19 Jul '08

19 Jul '08

Hi, I have been able to successfully use crash to examine a crash dump of kernel-PAE-2.6.18-92.1.6.el5 using the following command: crash /boot/System.map-2.6.18-92.1.6.el5PAE /usr/lib/debug/lib/modules/2.6.18-92.1.6.el5PAE/vmlinux ./vmcore I then installed the package kernel-debug-2.6.18-92.1.6.el5 and rebooted with that (there is no PAE debugging kernels in the repository). I reproduced my crash and collected a crash dump, however when I try to examine the dump I get the following error: crash /boot/System.map-2.6.18-92.1.6.el5debug /usr/lib/debug/lib/modules/2.6.18-92.1.6.el5/vmlinux ./vmcore crash: v2 module syment space malloc (2005518689 symbols): Cannot allocate memory I have used ulimit in the shell to set all of the limits to unlimited and I still continue to have this problems. Any ideas? Is it possible that I would need a 64 bit OS in order to examine a 4gb crash dump with symbols and debugging information? I have the following kernel-debuginfo packages installed: kernel-debuginfo-common-2.6.18-92.1.6.el5 kernel-PAE-debuginfo-2.6.18-92.1.6.el5 kernel-debuginfo-2.6.18-92.1.6.el5 I am running CentOS 5.2 on a dual Xeon Server with 4gb of memory. Thanks, Nataraj
