I listened to various news reports on > Saturday night, but they just referred vaguely to a "computer > glitch" or a "computer bug", without getting into any details. There's a brief article on it in The Globe and Mail today (http:.//www.globeandmail.com). The full URL that I got when I found the article is the elegant and easily remembered http://rtnews.globetechnology.com/servlet/RTGAMArticleHTMLTemplate/C/2001103 0/wxtdbank?tf=tgam/realtime/fullstory_Tech.html&cf=globetechnology/tech-conf ig-neutral&slug=wxtdbank&date=20011030&archive=RTGAM&site=Technology. It doesn't go into a lot of detail. (I think that banks are traditionally quiet about data processing problems.) Here are a couple of paragraphs that give a little information: The crash was caused by the failure of a single "motherboard" in one of the bank's central computers at about 11 a.m. Saturday. This "gradually started to shut down the system" to "protect the integrity" of the data already there, Mr. Livingston said. "It was a purely random event," he said, adding that hardware failures are rare. "This has never happened before, and it will likely never happen again." Although the bank's credit card system "stayed on the air pretty much all day," and its debit card system also continued to function "intermittently," Mr. Livingston said, everything else went down. This included its telephone and Internet banking operations, in-branch computer systems and approximately 2,000 automated banking machines. Customers also were unable to gain access to their money through other banks' ABMs. [...] As TD sought to identify and fix the problem, "a few million transactions" were rejected by the bank's systems, which, on a busy Saturday, process up to 500 transactions a second, he said. > > I'd really like to know what happened to > > crash their whole system.

Gilbert's theory sounds reasonable, especially since the credit card system was working for most of the time. I assume that the credit card system has an independent account database. - Doug

TD network failure
by author 29 Oct '01

29 Oct '01

Does anyone have any specifics as to why the Toronto Dominion Bank had that major failure this Saturday, October 27 ? All I hear in the media is that it was some kind of 'hardware' failure. Nothing specific said. I'd really like to know what happened to crash their whole system. I thought the banks had 'bullet-proof' networks what with all those billions of dollars they have to spend.

Tape Backup Software, comments.
by Brock Wolfe 19 Oct '01

19 Oct '01

I am looking for Linux tape back-up software for a small network of mixed OS PC's. I have looked at Amanada, Arkeia, and Tolis BRU. I am especially looking for support for HP "One Button Disaster Recovery" (OBDR), and centralized network backup. I have followed the Amanda mailing list and have feel for it's use. Are there any pros/cons to Arkeia and BRU ?

Red Hat 7.2 official launch
by gedetil＠cs.umanitoba.ca 12 Oct '01

12 Oct '01

Here's the official word from Red Hat... The launch date is set to be October 22nd, at 8:00am EST (-5/GMT). Hopefully, we'll be completely in synch with their site by that morning. (That shouldn't be too much of a problem, though, as they've been much more organised than usual, and have given mirror sites much more lead time.) -- Gilbert E.

Red Hat 7.2 review from ZDnet
by gedetil 11 Oct '01

11 Oct '01

Further to the October roundtable discussion about the imminent release of Red Hat 7.2, here's the ZDnet review I mentioned, which may be of interest to you... http://www.zdnet.com/products/stories/reviews/0,4161,2816836,00.html It mentions some of the key new features in this release, such as GRUB, ext3, and a new version of Gnome. (BTW, still no word on the actual release date, but it's still sounding likely to be sometime between the 15th and the 22nd.) Also, I've updated the meeting write-up on the web site to include links to the PDF file for Terry Baydock's slide presentations and handouts... http://www.muug.mb.ca/meetings/01-02.html#oct Enjoy! -- Gilbert E.

Just a warning. I received my renewal notice at the price of 1 yr $32, 2 yr $64. A month later another notice had the price at 1 yr $22, 2 yr $39. I do not know how low the price would go if I waited longer. ttyl, Bill ____________________________________________________________ Bill Reid Page 993 Dorchester Ave. Network Consultant, Retired 935-1432 Winnipeg, MB R3M 0P9 University of Manitoba (204) 452-6590

Logging and rejecting with iptables
by Sean A. Walberg 11 Apr '01

11 Apr '01

Further to the question last night on how to both log and drop a packet, it is done with an extra chain. I created a LOGGING chain with a default policy of ACCEPT. The first rule in INPUT was then to jump to LOGGING. Here is what I have (my apologies for any wrapping) [root@poochie /root]# iptables -N LOGGING [root@poochie /root]# iptables -A LOGGING -p tcp --dport printer -j LOG [root@poochie /root]# iptables -I INPUT -j LOGGING [root@poochie /root]# iptables -L INPUT -v Chain INPUT (policy ACCEPT 1730617 packets, 454636701 bytes) pkts bytes target prot opt in out source destination 42 2215 LOGGING all -- any any anywhere anywhere 5 300 REJECT tcp -- ppp0 any anywhere anywhere tcp dpt:printer reject-with icmp-port-unreachable ...
