I wish we could get an update if they are even _WORKING_ on a PHP update, or if they have just thrown in the towel and said we're not going to patch this. If thats the case, we'll upgrade, but not otherwise. By the way Debian relies on the work of volunteers. You are free to backport the patches to PHP 4.1.x if you find the time. I see the problems of the developers. Security problems are not properly announced, fixes are messed into other patches. By the way I bet there are a lot more flaws in this plain old version which got fixed on the long way to 4.3. In my opinion it is not worth to backport PHP 4.3 to stable as sarge *should* be released as soon as security team support is available.

MYSQL_SELECT_CLAUSE SELECT CONCAT(localpart, '@', domain), \

password, \

MYSQL_CHPASS_CLAUSE UPDATE users \
SET password='$(newpass)' \
WHERE localpart='$(local_part)' \

Although I don't know of the latter that it really works. You get rid of
all the other fields except of MySQL session information.
You could replace things like ``uid'' and ``gid'' to the integer value
used on your system (I used DEFAULT values in the table instead) like
common in SQL. There's also the possibility to use
CONCAT('/var/mail/vdomains/', domain, '/', localpart)
instead of the hackish way I chose.

Courier traffic accounting
Dear debian-isp list members, are there any ways of traffic accounting related to Courier POP3d and IMAPd? We need this on a per-domain basis. The accounting for incoming/outgoing mail is easy, as our mailserver of choice -- Exim v4 -- logs the message size. When looking through Courier's logs I didn't notice something similar on the close of the connection. I would appreciate any hints; if it gets written down once by anything, I would write a tool to parse/summarise that stuff.

Re: [mailinglists] Re: Trusting Backports and unofficial Repositories
Hi Craig, 1) Are you using unofficial repositories on production servers ? no, i run unstable on several dozen production servers without a problem. i find that doing that is an excellent way of both keeping software up-to-date and also keeping several months ahead of the script-kiddies. i upgrade, on average, once or twice a month by first upgrading my workstation (which generally has the same packages as the servers for testing and development) [...] first, thank you for you long and comprehensive answer, but we wont use unstable. we wont do for at least these two points 1) unstable packages are upgraded _very_ often. my workstation is testing, and i upgrade every week. there are always plenty of packages to upgrade. of course a server will not have that much packages installed, but its still way to much. 2) unstable is, as the debian developers put it, unstable. the major point is, that you cannnot chose to have a stable packages of, lets say, gd, but an unstable php. if you install the unstable php with gd support it will ask for the depended gd-version. so many packages will be unstable. i really don't see the point of stable+backports - installing backports defeats the original purpose of running stable, it's like saying i'll have a black coffee..but with a little bit of cream*, so you may as well run unstable. i dont think so. the purpose of debian stable is running a stable system and you still do to a certain point if you run a few backported packages. of course its not a black coffee anymore. if you have a firewall that guards every single port and denies every connection that comes in you might be pretty safe. if you now open port 80 to make the world connect to your webserver you are not that safe as you were before, so now theres some cream in the coffee. but there is also an advantage: people can connect to your webserver. its the same with backports in my opinion: using a stable system has the advantage to be stable. but for a few packages you are in the need for features. whats better now: putting some cream in the coffee or go for pure milk ?

Trusting Backports and unofficial Repositories
Dear All, we are currently running several machines with, of course, debian. as we need stability we are running woody, but we also dislike having old software on our servers: the stable version of php for example is 4.1.2 and php.net has version 4.3.8 for download (marked as stable as well). due to that gap we are using as many debian packages as possible, but compile software like php and others from source, to be up-to-date. but this procedure is very time consuming. looking for a solution i came across apt-get.org and the unofficial repositories and backports they offer. now heres my question: would you trust these archives for you production servers ? i dont think about security and malicious packages opening backports in the first instance. you always have this problem more or less, but about updates when a problem is found in a package. so heres a catalogue: 1) Are you using unofficial repositories on production servers ? 2) Is there a list of trusted unofficial repositories ? 3) What about updates if a problem is found in a package ? In connection with question 2): Can you recommend repositories, which proved quick response to problems ? 4) What about security.debian.org ? If a vuln is found and security.debian.org gives out a fixes version, and i gave security.debian.org and the unofficial repository in my sources.list, what will happen ? I dont think this kind of question has not been discussed before, but i couldnt find anything related searching debian-isp archives. plz point me somewhere, if this has been discussed allready. thank you very much, philipp -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Do you know why ext2 sync-mounted is so abysmally slow? I mean, our RAID was barely breaking a sweat, and bonnie++ was barely using 2-3% CPU, and yet, things just wouldn't go any faster, what's the bottleneck? Write back caching is simply a great way of improving performance. If you have a single hard drive then when writing to a file, even if the data is all contiguous (the file is not fragmented) then when writing data for each write the disk will need to spin to the correct location before data can be written, for a 10K rpm drive that'll be an average of 3ms overhead per chunk. Use a larger chunk size for Bonnie++ and performance should improve. Also for a RAID-5 it's even worse. To write to a sector on a RAID-5 you have to do two reads and two writes minimum (or a read from all disks minus two plus two writes) to get the correct parity. For a three disk RAID-5 that's one read and two writes, for a five disk RAID-5 it's two reads and two writes. If you write the entire stripe at once (could be dozens of blocks depending on the RAID setup) then it's little overhead when compared to a non-RAID setup (RAID-5 should perform well for writing big files non-synchronously). Again make the chunk size larger on Bonnie++ and you should see a good performance improvement. You might even discover that the performance of your RAID setup can be measured in synchronous writes per second rather than any other metric. within this discussion, i got the idea to put an external journal for the ext3fs on an raid1-volume the real data on a raid5, hopefully, when writing the journal out to the disk having more data to be written an once - this would be worth a try but i don't have the hardware to try this and bad expirences with software raid5.

Re: [mailinglists] slow telnet and ftp connections
Hi, the problem is the DNS Lookup. check your DNS Settings, that should solve the problem. regards, Philipp Am 05.03.2002 11:41:19, schrieb [EMAIL PROTECTED]: My System: potato with the security updates. proftpd telnetd My Problem: telnet and ftp (local network) connections to my server from win clients (CUTE FTP, MSIE, Putty ...) are very slow: The Telnet running is not slow when connection is done, so the anoying thing is just the connection. Linux telnet client connect to the server very fast. But Win telnet client also connects to another server out of the network very fast ?! So I don't know which could be the problem?

Re: [mailinglists] Re: Debian GNU/Linux as email DNS server
I suggest DJB's qmail. You can get the Source Tarball at http://cr.yp.to (official) or http://www.qmail.org (unoff). Qmail is the most powerful MTA i ever saw. Various big freemail provider use qmail, like GMX for example and even Microsofts Hotmail Service uses (or is still using) qmail as outgoing mailserver.

RE: [Exim] Tarpit SPAM trap
We send copies of this spam to [EMAIL PROTECTED] on a daily basis. The only response I have ever had from AOL is from an autoresponder. hmm... From my experience AOL has always been quite cooperative in such cases, though we always called them directly when there was a major spam problem... -philipp
