I can't seem to access the "Last Day" or "Last Week" features. I even deleted all cookies to see if it was a problem on my end. This is what I get when clicking those links:
I wanted to know if anyone else is having trouble before I "contact the server administrator" (although I am certain Ian will see this thread nearly as fast). -Sean http://OurOdyssey.BlogSpot.com | ||

Hi folks, I'm going to have to look at this problem in the morning, so please bear with me. This error can occur when the search engine get's too "full" of indexed messages, but I have just run the diagnostic and reconfiguration of that and it hasn't made a difference. The board's general diagnostic shows everything is fine and that all scripts are correct and running perfectly, which leads me to believe the problem is in the permission file, which may have been inadvertently adjusted. I don't have access to that today, but I will in the morning. In the meantime, the only parts that appear to be not working are the search last day and search last week links. Please feel free to check each thread if you can recall where you "left off" last time you were here. I apologize for the inconvenience. Ian www.busnut.com | ||

Well folks, hope this never happens to you but this board has been the victim of a DOS attack and the server shut down. In response, the search script has been disabled. It might take some time to enable the the search scripts again but please hang in there, I'm trying to get a fix. Meantime, please just use the default topics page to follow threads. Instead of searching, please feel free to ask the question that's on your mind. Thank you again for being patient. Ian www.busnut.com | ||

Ian- I am so sorry to hear that. In the mix of things, you have a tier group of clinets, handleres, and agents. A DOS attack is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DOS attack may vary, it generally consists of the concerted efforts of a person or people to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely. Behind one of the Clients is a person that orchestrates the attack. A Handler is a compromised host with a special program running on it. Each handler is capable of controlling multiple agents. An Agent is a compromised host that runs a special program. Each agent is responsible for generating a stream of packets that is directed toward the intended victim. Attackers have been known to use these four programs to launch DDoS attacks:Trinoo, TFN, TFN2K, Stacheldraht. In order to facilitate a DOS attack, the attackers need to have several hundred to several thousand compromised hosts. The hosts are usually Linux and SUN computers but the tools needed can be ported to other platforms as well. The process of compromising a host and installing the tool is an automated process that is/or can be divided into these steps in which the attackers 1.Initiate a scan phase in which a large number of hosts (on the order of 100,000 or more) are probed for a known vulnerability. 2. Compromise the vulnerable hosts to gain access. 3. Install the tool on each host. 4. Use the compromised hosts for further scanning and compromises. Because an automated process is used, the attackers can compromise and install the tool on a single host in under five seconds leaving several thousand hosts compromised in under an hour. Characteristics of Common Programs Used to Facilitate Attacks There are common programs that hackers use in order to facilitate distributed denial of services attacks. 1. Trinoo which Communication between clients, handlers and agents use these ports: 1524 tcp 27665 tcp 27444 udp 31335 udp Note: The ports listed above are the default ports for this tool. Use these ports for orientation, troublshooting and example only, because the port numbers can easily be changed. 2. TFN whic Communicates between clients, handlers and agents use ICMP ECHO and ICMP ECHO REPLY packets. 3. Stacheldraht communicates between clients, handlers and agents use these ports: 16660 tcp 65000 tcp ICMP ECHO ICMP ECHO REPLY Note: The ports previously listed are the default ports for this tool. Use these ports for orientation,troubleshooting and example only, because the port numbers can easily be changed. 4. TFN2K- Communicates between clients, handlers and agents does not use any specific port , for example, it may be supplied on run time or it is chosen randomly by a program, but is a combination of UDP, ICMP and TCP packets. These are suggested methods to prevent distributed denial of service attacks. 1 Use the ip verify unicast reverse-path interface command on the input interface on the router at the upstream end of the connection. This feature examines each packet received as input on that interface. If the source IP address does not have a route in the CEF tables that points back to the same interface on which the packet arrived, the router drops the packet. The effect of Unicast RPF is that it stops SMURF attacks (and other attacks that depend on source IP address spoofing) at the ISP's POP (lease and dial-up). This protects your network and customers, as well as the rest of the Internet. To use unicast RPF, enable "CEF switching" or "CEF distributed switching" in the router. There is no need to configure the input interface for CEF switching. As long as CEF is running on the router, individual interfaces can be configured with other switching modes. RPF is an input side function that enabled on an interface or sub-interface and operates on packets received by the router. It is very important for CEF to be turned on in the router. RPF does not work without CEF. Unicast RPF is not supported in any 11.2 or 11.3 images. Unicast RPF is included in 12.0 on platforms that support CEF, which includes the AS5800. Hence, unicast RFP can be configured on the PSTN/ISDN dial-up interfaces on the AS5800. 2. Filter all RFC-1918 address space using Access Control Lists (ACLs). 3. Apply ingress and egress filtering using ACL's 4. Use CAR to rate limit ICMP packets 5. Configure rate limiting for SYN packets. Note that if you set the burst rate greater than 30%, many legitimate SYNs may be dropped. In order to get an idea of where to set the burst rate, use the show interfaces rate-limit command in order to display the conformed and exceeded rates for the interface. Your objective is to rate-limit the SYNs as little as necessary to get things working again. If an SYN attack is aimed against a particular host, consider installing an IP filtering package on that host. One such package is IP Filter . Refer to IP Filter Examples for implementation details. Of course the above is router specific to which I do not know that you control but at least you can be armed with information. Hope this helps and Good Luck! Kade | ||

Hi folks, For those interested: It was a frequent Yahoo crawler that was providing 99% of the problem with one script so I adjusted the robots.txt file to delay the frequency it will search. If it ignores the file, I will ban access from their IP address altogether. There were also about a half dozen or so IP's that were trying to access the search engine so frequently that it looked a little suspicious. I have banned those IP's. Our regular users will likely not be affected by this action, but I'll keep my eye on it. And for those who have no idea what you just read, suffice it to say that the search engine is running (has been for a couple of days) quite normally and, therefore, if you used the "Last Day" and "Last Week" search function at the bottom of every page, it now works as if nothing had ever happened. Here's an aside: I have been long contemplating... and sought the advice and opinion of my good friend Buswarrior... the purchase of a new and modern bulletin board programme that will handle the incredible size and load of BNO's BBS. The current system, while not broken, is very ancient and the developer has more or less given up on updating it. Please don't anyone say, if it aint broke don't fix it, ok? It ain't broke, but this is the internet - there are bigger and better things to make both the internet and your computer work better. And that's where I'm always heading with this web site. I willingly accept your comments and suggestions. If you know of a bbs that works beautifully elsewhere, please let me know. Although I likely already know of its existence, I'm happy to hear your comments about your choices. Now, here's the caveat: the software you recommend MUST, I repeat, MUST accept the conversion of this bbs readily and with a proven track record. Please don't bother me with something that doesn't do that. It's a waste of both our time. Anyhoo, thanks for your patience everyone, for enduring this little glitch in the server. I think we're pretty much out of the woods with this particular problem. Though I will be making very minor tweaks throughout the rest of the week, you'll notice nothing, I promise. Thanks everyone! Enjoy :~) Ian www.busnut.com | ||

Hey Ian thanks. As for your commet, I would suggest SMF for you to take and give a peek. They do a great job, very proffessional looking, and the adim area is very user friendly with tons of features. Just my input. Good luck. Kade | ||

oh dear... I share Ian's historical concern for those many busnuts who have slower internet connections. There are many, many people who live where there will never be high speed internet, and/or who choose to not spend their money on anything more than a basic connection. My vote goes for whatever compromise gives those folks the quickest and slimmest downloads, while keeping our ongoing collection of knowledge reliably safe, functional and well supported. Unfortunately, it seems there aren't a lot of software developer types out at the end of a dial up connection? happy coaching! buswarrior | ||

Agreeded..what the warrior expressed so no need to repeat. Teresa- FIrst you start by poping the cork on a bottle of burgendy and then insert batteries in the DVD remote. Find the little button that says ON/Power. But then you will need another bottle...LOL Kade | ||

My mom had Windows 98 that was installed by the factory on her computer that she used dial up for! She used this same set up until this past year when I came to take care of her. She had been complaining about people sending her photos and stuff and that EVERTYHING was very slow and that she didnt have time to do the puter anymore. I tried to explain to her that she was riding a horse with a gimpy leg on the freeway with the other people all driving corvettes and she just could not keep up. My brother had a puter special built for her (very very nice and very high tech with Windows Vista) while I ordered broadband and put in a good wireless router so I could pick up the signal at her house. Now she just wizzes along and can keep up on her email and facebook with the family. She did not know that her system was obsolete but was ready to throw in the towel and not use the internet anymore because it was so slow. These days it is not too difficult to pick up a Windows XP on a decent puter in a thrift shop even for less then $100.00 High speed internet OTOH is a little more expensive but is coming down all the time and is affordable for most people. Even Kamiah Id (pop about 1130, depending on hunting season) now has high speed internet. I dont know about other countries, but I do know it is spreading FAST. Having the "fastest", "newest", "shiniest", etc. is not important to me anymore (lol look at my bus for proof). BUT with the internet........ that is another story. The fastest, newest, shiniest is also the most secure from attacks. The new anti-attack scripts are written for the newest, fastest, and shiniest. There are tonz (and the list keeps growing) of attack scripts written by hackers and wannabe hackers for the older systems/computers/servers For security purposes, the newest systems are by far the safest. Now, back to trying to program my dvd player..... or ah,..... I like the way you think Kade!!! (Message edited by happycamperbrat on August 24, 2010) | ||

This is what I mean by don't suggest it unless you know I can convert this bulletin board system.  See? No Discus converter. Thanks. Ian www.busnut.com |
