need advise: productive HDD is down
Hello All! On Friday during thunderstorm productive HDD on our mail machine, though being connected through UPS, fallen down with interesting symptoms. Is boots as usually, LILO and other stuff but when it is time to mount root partition, kernel panics with error Cannot mount root. When connected it to another Debian (of course :) machine, fdisk says all partitions are ok, this 3G, this 1G etc. but mount refuses to mount any of damaged partitions. fsck (e2fsck) refuses to fix anything telling different things on different partitions, Cannot mount FAT due to some blah blah blah or superblock is damaged try to run e2fsck -b 8193 blah blah blah which is also failed (I mean e2fsck -b 8193). Are there any tools to explore and optionally restore damaged ext2fs as we have clients mail and some sites there? Please advise some package names to look at. -- Sincerely, Dmitry Litovchenko -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Router machine falls into APM sleep :(
Hello, respectable ISP community :) I am Internet-administrator in University (see my email :) and on small ISP. Got one problem with my router PC. All of my PCs are Debians and one onf them, approx. month ago installed directly from Internet (with boot floppies and LAN cable) if this matters. So this PC got an ugly habit to go to APM (or whatever?) sleep if not used for some time. This is not bad, but it holds leased line client connected to 10Mbit NIC and 6 dialin modems on multiport card... At this time they cannot work at all, modems accept login but pppX interfaces do not route! Leased client can ping our server but can't ping Internet. If one press any key (for example Shift) on Router keyboard, routing quickly goes up and all things restore. No APM daemons were found running in memory using 'ps fax' command. No APM options were sut up in BIOS (afair) and it has set up in BIOS to wake on any events, including LAN events. Please tell me where to dig? My boss kicks me every day for this :) -- Sincerely, Dmitry

Re: Virus scanners
Hi all, Can any body suggest a decent virus scanner for Linux? I've heard that Sophos is good, but its a bit pricy... But anything that'll work with amavis would be a great help. Thx in advanced. Simon Please visit www.avp.ru (you will need to look for English version on the title page if you're unfamiliar with Russian :) There is Antiviral Toolkit Pro - antivirus scanner fior Linux, FreeBSD and Windoze servers and workstations. I didn't try Linux version yet, but windoze version is popular in Russia and Ukraine, not legal copies, of course, most of us here cannot buy commercial software :) Maybe pricing may satisfact you... For example such an software is present (my mailer told me so) on freemail.ukr.net webserver, etc. This is good antiviral software to play with. There is demo for RedHat workstations... -- Sincerely, Dmitry

Re[2]: Have you been hacked by f*ck PoizonBOx?
Potantialy I am in danger, because I use a ISDN-Flatrate and I am connected 24/24 and 7/7 to the Internet. And now I have 7 MBytes of logs in less then 2 hours. Michelle Would you be interested in sharing the attacking IP with us so that we can blacklist it? You can try to install Portsentry product (seek it at freshmeat.net) to autoban attacking IPs with your firewall. And then, when attack will calm down, you can analyze IP list and do anything you want :) -- Dmitry
Re: TCP connection problem.
I have a tcp connection problem. I connect to the Internet using a Debian 2.2r2. Some web servers refuse to respond to my requests. No matter witch browser I use (Lynx, Netscape Opera), they access the web servers but no data is transferred from them. The servers seems to run on Windoze NT 4.0. One example of this is www.conexant.com I try telnet webserver.com 80 and after connection I send a request like a browser do, but the response does not come. I suspect somme tcp connection problems. If I use a proxy from the net all works fine. Those servers seem to check if your IP can be reverse-resolved to an internet domain name. If you do have external IP (e.g. not masqueraded by your ISP) then you should have your IP to be written in DNS reverse-lookup tables, ask your ISP to do so or do it yourself if DNS in on your machine. This could help. Could be my kernel (custom 2.2.19) the source of this problem ? Please help ! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

TCPD with traffic shaping capabilities?
Hello, Debian world! Does anybody know how to limit incomming (and maybe outgoing) traffic on tcpd-wrapped service. Some kind of tunnels or queues, I think. Yes, yes, I know traffic shaper works only on outgoing traffic. Yes, I have this. But also I have incoming traffic to shape and just don't know how to do that. While squid does this well with delay_pools, sendmail (for example) can receive unneeded mails with 300MByte game all night away. Okay, I have set mail limit to 2MB per mail, but two nights later situation repeated, when I had full pool of unsent mails (mass mail) which unsuccessfully tried to deliver all the night. Again traffic load was totally up and while we are paying for traffic percentage per month I do not want to have my load graphs 100% up. Maybe tcpd has some options (I haven't found any yet) or another tcpd wrapper? -- Sincerely, Dmitry
Apache does not recognize POST method
Hello everybody! Here is one little question. I am up and running Debian on small University network to serve web pages and to allow internal users to be online and the question is: My Apache servers local on Windoze machine and on Debian server both do not recognize POST method in HTML forms, to make my sites work I should replace form method=POST by form method=GET in pages. This is because Squid or Apache loses HTTP headers where POST data is stored during request. This problem began after my Mandrake server become Debian one and persists almost 3 months. As this problem does occur even on Windoze machine I think Squid has no relation to this problem. Does anybody know how to make HTTP POST method work in Apache? Some modules to include? -- Sincerely, Dmitry -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
Re[2]: Apache does not recognize POST method
To Dmitry: Do you have apache and squid running on the same box? Yes I do. Every connection to outer world's ports 80, 8080 and 3128 is transparently IPTABLE'd through squid on the same box. What type of file are you posting to? for example: .txt, .html, .pl, etc... Just Python scripts: .py files What is the error? a snip from the error_log would help. The problem is that script does not see form fields passed through POST method (invisible data in request header). Apache logs tell nothing, squid logs, as it seems, too. What version of apache and squid are you running? Russian port of Apache. Server version: Apache/1.3.14 (Unix) Server built: Apr 18 2001 09:56:02 To people, claiming that Russian Apache can be sucks, I can say that problem has began much before the time when Russian Apache came to my Linux box. $./trent [EMAIL PROTECTED] - Original Message - From: Dmitry Litovchenko [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, May 21, 2001 2:33 AM Subject: Apache does not recognize POST method Hello everybody!
