help with user quotas
Howdy folks, I'm setting up a Deb woody server and want quota support on /home just in case we need to get serious. I have quota support in the kernel and the following in /etc/fstab: /dev/sda6 /home ext3defaults,data=journal,usrquota 0 2 I run #quotacheck -c /home and get this: -rw---1 root staff7168 Aug 28 12:11 aquota.user in /home. However, when I run: #quotaon /home I get this: quotaon: using /home/quota.user on /dev/sda6 [/home]: Invalid argument quotaon: Maybe create new quota files with quotacheck(8)? hmmm. ??? at first I thought it was due to quotaon not wanting to use version2 quota files, so I had quotacheck create one of those (quota.user) and i got the exact same message. I can't believe I can't get something this simple to work. any ideas? ext3 is mounted data=journal, could that be it? thanks, Dave -- *** David Wilk System Administrator Community Internet Access, Inc.

SpamAssassin PHP-SA-MYSQL
I've tried searching web pages for assistance with this issue but have not found anything relevant. While attempting to use the PHP-SA-MYSQL interface to allow clients access to their options, I keep getting an error message saying it is attempting to connect as '[EMAIL PROTECTED]' while the configuration variables are set as follows: $dbhost = "localhost"; $dbuser = "spamby"; $dbpass = ""; $dbname = "spamassassin"; I can manually connect to the database as '[EMAIL PROTECTED]' using the shell 'mysql' command, but the PHP script still attempts to connect as '[EMAIL PROTECTED]'. I've restarted Apache several times without any success.

If the resolved host name is longer than len, the dotted decimal value will be used instead. This allows hosts with very long host names that over- flow this field to still be uniquely identified.

disabling reverse map of addresses
Hi all Anyone knows how to disable reverse lookup of IP addresses in sshd et al? I've got a box connected to the net with a dynamic IP and dynamic dns service, and the wait time for ssh to present a prompt after not finding a reverse map for a given address is kind of annoying... Thanks -- José
Apache variables
Hello, I can't get the variables PATH_INFO and PATH_TRANSLATED, the answer is always null. Everything else in cgi scripts seems to work fine. SERVER_SOFTWARE = Apache/1.3.26 Ben-SSL/1.48 (Unix) Debian GNU/Linux PHP/4.1.2 snip... PATH_INFO = PATH_TRANSLATED = SCRIPT_NAME = /test/cgi-bin/getenv2.cgi snip... I tried on several servers I use, whithout any difference, despite uncgi, which should use these vars, work fine on those boxes. Well, if any of you know something about my problem... Thanks all Alexis

Re: Spam Assassin
I'm using Spamassassin, interfaced with exim to filter before delivery to local users. It works really well -- it catches 40-50% of incoming mail (for about 7 users total) as spam, with a false-positive rate of way less than 1%. I've seen a slight increase lately in spams that slip through, but typically my inbox gets three or four a day, which still isn't too bad. I dump all the suspected spam into a separate mailbox, which I check every couple of days by scanning the combination of subject line and sender. When I do that check, I may find one or two messages out of several hundred that I forward on as likely "real" email.

This can buy you more than standard compression, because 90% of http is uncacheable, and most of the volume is uncompressable images. The rsync style delta updates "update" the uncacheable-but-unchanged images with negligable traffic. You can setup an rproxy in Australia using an Asian rproxy parent, giving good delta compression between the two. A decent proxy setup with rproxy for relevant traffic might work out OK. Unfortunately rproxy has not been updated for ages. I keep meaning to do something in Python but never find the time. For other traffic, a compressed tunnel would be pretty simple... just make your tunnel to asia the default route. I'm not sure it would buy you much other than latency though :-( -- -- ABO: finger [EMAIL PROTECTED] for more info, including pgp key --
Forward to Razor (Re: Spam Assassin)

Yeah, but one should be a bit careful about depending on any AI to forward to Razor. I've put up some troll boxes for that (including these addresses in web-pages, send them to Remove-lists, etc). Those go (will go, anyway) directly to Razor, as they will never receive legit email. However, what I really miss is a pine-style pipe in KMail, so that I could pipe messages getting through the filter manually to Razor more easily. But I know the KMail folks are thinking about it.

AW: Spam Assassin
Hi, use it since a few months with postfix on woody out of the box. i got around 100 Spam hits for 30 Users in a week. less than 1% false positives. But still a spam get through. (1 to 5 mails per user and day) :/ At first i had to put some newsletter to the white list, but since then it just sits there an filters I noticed that any HTML Mails is a nearly sure hit... The thing i miss is a (more automagically) forward to razor. Won't miss it any more. -Ursprüngliche Nachricht- Von: martin f krafft [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 3.

Re: Bandwidth... compression... saving $$?

We use uucp mail for dial-up mail servers. The mail is routed into our main server with smtp. We compress each file with gzip before dropping it in a uucp spool. Each dial-up server collects its mail via uucp, uncompresses with gzip and then feeds it on to exim for local delivery. We handle 300 to 500 mB of this mail per day. I have never stopped to check what the compression ratio of incoming to outgoing e-mail is. However the outgoing volumes are significantly lower. Anti-spam and anti-virus stuff on the main server filters out quite a lot junk too. How about getting yourself a server in HK. Set it up with uucp + gzip, and download it from your server in Australia. At least this is much simpler to setup than tunnels etc. The uucp is extremely solid - it never looses a byte of mail. Another consideration though, is the ratio of local to international e-mail. We have a similar (probably worse) situation with monopoly pricing in South Africa. I have considered hosting our mail server overseas. But that would mean a lot of mail gets round tripped, from SA overseas and then back to SA.
