Greetings: In R parallel's vignette, there is a comment "It would however take only slightly more work to allocate a stream to each task." (p.6). I've written down a working example that can allocate not just one, but several separate seeds for each task. (We have just a few project here that need multiple streams). I would like to help work that up for inclusion in the

Dear all, The other day I stumbled on this article, "A critique of R and S-PLUS" [1], and got curious on whether the points outlined are (still) valid. The article is quite old, dating 2004, but was updated several times.

Hello: I have been looking into projects that will automatically restrict hacking attempts on my servers running CentOS 5. I think the two top contenders are: DenyHosts - http://denyhosts.sourceforge.net Fail2ban - http://www.fail2ban.org >From what I see, DenyHosts only blocks based on failed SSH attempts whereas Fail2ban blocks failed attempts for other access as well. The main benefit

Hi, after reading the docs (no man page) and seeing a few example howtos, I see none for Centos specifically. I hereby offer to write this and even host it, and any other wiki-able howto you want, if you can school me on the first few steps relevant to how to link up the current rpmforge rpm for RHEL4-64. See, right now, the one for centos loads into the /usr/share/doc, which is an odd place

Hello, I've installed denyhosts on centos 5.3 trying to block automated attacks on ssh. It appears to be working in that entries are being added to /etc/hosts.deny yet the daily emails sent from denyhosts show only one ip being added perday when the total is many more than that. My config is below, i've gone over it and am not seeing what i missed. Suggestions welcome. I was also

I have just started laying out the plans for my first project using Asterisk. I am very interested at this stage in getting much needed feedback, critiquing my approach. What are the ups and downs going to be if I develop this project as follows: -The client wants to connect some phone reps in India through a VoIP to their clients. -There will be 3 phone lines, and 1 broadband internet

Hello, What is the best way to protect multiuser systems from brute force attacks? I am setting up a relatively loose DenyHosts policy, but I like the idea of locking an account for a time if too many attempts are made, but to balance this with keeping the user from making a helpdesk call. What are some policies/techniques that have worked for this list with minimal hassle? Thanks! -Eugene

I'm looking for a way to deny access to dovecot from certain IP addresses, basically to help prevent brute force attacks on the server. Right now I'm using denyhosts which scans /var/log/secure for authentication failures which then can add an entry to /etc/hosts.deny, but since dovecot doesn't have tcp wrappers support, that doesn't do anything. It doesn't look like I can

Hi, i have one centos 4.3 box, exposed to the internet. since several weeks ago, i found numerous attemps to connect through SSH, but failed. they tried with many username, including root. it's comes from different IP. some of them are foreign website. How do i make my centos become smarter in handling this kind of attacks. eventhough i've disable all the user accounts, left only the

I'd like to see a feature of the commercial ssh in openssh: AllowHosts xxx.yyy.xxx.yyy *.domain.net DenyHosts xxx.yyy.xxx.* name.domain.net This allows or denies connects from certain machines (including wildcard matching). Is there any chance for this feature to be included? No, we don't want to use tcp-wrapper for this. Bye.

Hi, to prevent scripted dictionary attacks to sshd I applied those iptables rules: -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -m recent --update --seconds 60 --hitcount 4 --name SSH --rsource -j DROP -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -m recent --set --name SSH --rsource And this is part of logwatch: sshd: Authentication Failures: unknown

I need to buy some new phones for our own offices. I've used only Polycom phones until now, but I'd like to broaden my experience. I'm trying to decide which phones to experiment with. I have these options: - A combination of Polycom, Aastra and Snom - Just Polycom One the one hand, I'd like to keep things uniform, since it greatly simplifies provisioning. On the other hand, I

Hi all, ?Is there any app like denyhosts[1] but intended for MySQLd service? We have a mysql ports (3306) opened for remote connections, and obviously the /var/db/mysql/machine_name.log is full of these kind of entries: ........... 936012 Connect Access denied for user 'user'@'85.19.95.10' (using password: YES) 936013 Connect Access denied for user

Hi, I just set up a web server... and my bandwidth is being eaten by some chinese folks trying to brute-force-ssh their way into the machine. Is there a simple way to banish either single IP addresses or, maybe even better, whole IP classes ? I know it's feasible with iptables, but is there something more easily configurable ? Cheers, Niki

Situation: We are providing hosting services. I've grown tired of the various kiddie scripts/dictionary attacks on various services. The latest has been against vsftpd, on systems that I can't easily control vs. putting strict limits on ssh. We simply have too many users entering from too many networks many with dynamic IP addresses. Enter.... thinking about LIDS or Log Based

I have in the sshd_config the following to disable password authentication Match Group dummies PasswordAuthentication no KbdInteractive no Normally I use denyhosts to detect incorrect logins, but it seems that failed sshkey logins are not logged in auth.log And I really like to have them in order to detect them and use the denyhosts script. Looked in the last nightly builds, but it

ear folks ? I have a question, though it is more of a logic- or a good practices-question than a programming question per se. I am working with data from the American Community Survey summary file. It is mainly categorical count data. Currently I am working with about 40 tables covering about 35 variables, mainly in two-way tables, with some 3-way and a handful of four-way tables. I am going to

Hi all, I appologise in advance if this is a little OT, but I am building a box that will serve as firewall and router for a small ''internet cafe / netcafe'' and am using CentOS... So here it is: What are the best tools to be used for keeping the potential script kiddies from ''harming the Internet'' :) ? I specifically want to be able to detect and prevent
