There was a couple of months it was very effective, but that is long gone. Spammers aren't stupid, and they follow the development of anti-spam techniques as much as e-mail admins do. Greylisting is a start, but from my experience it is not nearly enough. I have heard this said elsewhere too. Yes don't rely solely on greylisting unless you're a lucky guy and don't get a lot of spam. Also I believe that rejecting e-mail is a big point of discussion. We had an internet e-mail environment built about 3 years ago, and there the users were terrorized by spam. We had some users getting 30 spam mails a day at least. This setup was running amavis, spamassassin, postfix, postgrey, dcc and razor. Unfortunately, over time the bayes filter got incorrectly trained, and it sometimes rejected valid e-mails. If there's something you DON'T want to happen it's that. And also troubleshooting those kind of things can be quite hard ... What about CRM114 and dspam? I played with dspam at home but I didn't really got it running as I wanted to. I didn't invest an awful lot of time in it though, so I cannot properly judge it. I never heard of CRM114, so I cannot say anything from that. Have you ever tried statistical filtering instead of heuristics with spamassassin? We rebuilt the environment from scratch. Right now we are running OpenBSD spamd + OpenBSD Packetfilter. This functions as greylisting / greptrapping in combination with the PF firewall. We made a couple of scripts to trap invalid / forged e-mail addresses that are greylisted. Also we make use of the uatraps / nixspam traplists, and our own generated blacklist generated from spam being sent to the postmaster. We had some problems with blacklisted entries in the past, but we worked around that. It goes further then that, but I will spare you all the details. pf(4) has some amazing features that come in handy for spam control. I guess it forms a key component of any spam blocking architecture. And it works in concert with the other OpenBSD niceties you point out like populating the tables with blacklists and whitelists, greytrapping and using the pf(4) anchor mechanism to automate stuff. Indeed. PF is very powerful and uses very little resources. Hats off to the OpenBSD guys for this. And indeed, I can recommend every e-mail admin to use a pf and spamd combination. It's awesome and you can do a lot with it. Check out the OpenBSD website for more info. The probability and state tracking options in pf(4) are pretty interesting too if used creatively. Very much so, it opens a lot of new options for you to handle blacklisted entries. On the second line we run Postfix / ClamSMTP / Clamd / Spamassassin. We removed Amavis because it was annoying to upgrade and we wanted to get rid of it, as we had problems with it in the past. With SpamAssassin we use sa-update and sa-learn to keep the rules up-to-date and make sure bayes gets properly trained. So we are marking e-mail as spam and no longer block it. Why? Simple ... we no longer want to block false positives. Again, there is more to this, but I will spare you all the details. But if you don't update virus signatures wouldn't that cause worms and malware propagation? I know I am digressing but I thought signature updation was critical to malware control... Well of course, but with clamd I also ment using freshclam :) So we keep our signature database up-to-date as well. Right now we have 2500 happy users. Their local helpdesks helped them with getting an Outlook rule in place to automatically move tagged e-mails to a spam folder. Just like their gmail, hotmail or Yahoo account does at home. Wow, this is great. I am not surprised to hear this. ;) The environment we have is certainly not the easiest one, but we automated many things, leaving us with practically no work on it. All the updating of rulesets / blacklists / whitelists /whatever goes by itself. Downside of an environment like this is that you will need quite some knowledge of all the components and how they work together. But hey, I got it running at home as well (a bit simpler though) and didn't had a single spam mail in my mailbox the last 4 months. Sure, the ones I do get are getting tagged and moved to my spam folder automatically, which I do with maildrop (though procmail does the job nicely too). All in all it works like a charm. Using the X-foobar headers I suppose? I just check the Subject header to see if it starts with *SPAM*. So yes, using the mail headers :) Well a long story, but maybe it is of use for someone else. As always, YMMV. Yes, very enlightening, many thanks. Glad to hear. Jorn ___
RE: Suggestions please for what POP or IMAP servers to use
-Original Message- From: Matt LaPlante [mailto:[EMAIL PROTECTED] Sent: Saturday, December 15, 2007 2:18 PM To: Ted Mittelstaedt Cc: Andrew Falanga; Rob; FreeBSD Questions Subject: Re: Suggestions please for what POP or IMAP servers to use It's a chicken and egg problem. There's nothing wrong with writing an extremely strict standard. The issue is the implementation. If your server implementation is so strict that most clients have difficulty, then users will find something else and your standard will end up on the dustbin. It's better to start out with a strict standard and a forgiving server implementation, then as it falls into mainstream use, work with the client developers to correct their stuff. You've effectively described dovecot here. No, I haven't. Its codebase is perhaps designed to be very strict, however the same codebase also includes configurable 'workarounds' (enabled by default in many distros) for clients that are not up to spec. They're trivial to toggle and well documented. If you download and compile dovecot then is the default config template that is shipped with it enable the workarounds? No. The excuse that enabled by default in many distros is merely an excuse. Nobody who is serious about building a server for a lot of clients is going to be using some precompiled version, they are going to compile from source so that if a security hole is discovered they can patch it immediately. IF the switches DISABLED the lax behavior, and the defaults in the config templates were to not have the switches triggered, then it would meet the definition of a forgiving server implementation. But it doesen't even go that far. So, this meets both criteria that it will just work with clients now, and the clients themselves could theoretically (good luck with Outlook) fix their code in the future. Outlook works just fine in IMAP mode with uw-imap, both regular Outlook and Outlook Express. As far as I'm concerned, it's a fairly ideal environment, It is good you spell out that this is your personal ideal. and I'm glad the developer has gone to the trouble to 1) stick to standards in the core code and 2) made a point of documenting and providing workarounds for buggy clients. It is a lot of extra work to encapsulate all the alleged bugs in separate code so you can provide switches for stick-up-their -asses-admins to flip. That is work that should have gone into speeding up the code. It is utterly wasted effort unless your goal is to allow admins who have penis envy the ability to jerk people around for their choice of e-mail clients. It isn't the mailserver administrator's business if Joe Idiot User who doesen't know any better chooses to use Outlook 97 as an IMAP client, to deny Joe Idiot access to the mailserver. The admin does not need to be playing silly games like this, setting up his server so that only some clients can work with it, others can't, then telling people their software of choice has bugs and fuck you, don't use it. Programmers jobs are to makes things work for users. If Mickeysoft's programmers cannot write a decent IMAP client, then if the developer of an IMAP server can write around the problem, then he should do it and embed the fix in the server code without calling it out in a config switch. The situation is absolutely no different with hardware drivers. Take a look at for example the comments in the ne2000 (ed) driver code, or the DEC/Intel 21143 network card driver code (or man page) There are a number of very badly borked up hardware implementations of those network chipsets. Yet, do the driver authors of the ed or dc driver make the admins flip switches in the driver to make the driver work with their particular borked-up chipset implementation? No. They write the driver code to work with all implementations, even the borked up ones. The dovecot author is engaged in technopolitics. It is a very bad thing to do. Whether the authors of bad IMAP client software deserve this is beside the issue. You need to understand that the ONLY lever that the Open Source community has to keep the giants like Microsoft paying some kind of attention to published standards so that everyone's stuff can interoperate, is the moral superiority lever. In other words, the Open Source community simply does not engage in predatory, circle-the-wagons, use-my-stuff-or-else behavior. We have worked a LONG time to get to this point. As a result of this, when there IS a problem between the commercial stuff - like for example Microsoft's Networking, and the Open Source stuff - like for example, SAMBA, everyone always assumes that the problem is due to the commercial software companies breaking things - either deliberately, in which case they look like assholes or sharks, or by accident, in which case they look like incompetents. Microsoft tested stuff like IE7 against Apache during IE7 development, and they made

Re: OS bug in taskq
On Sat, 15 Dec 2007, Elliot Finley wrote: in the kernel and I'm still unable to obtain a crash dump. Hopefully there is enough info in this email for a hacker to point me in the right direction to debug this. If you're unable to obtain a crash dump, you should still be able to use interactive console-based debugging with DDB. I find this is easiest to do with a serial console from an adjacent machine, so that I can copy-and-paste the results into an e-mail rather than hand-transcribe. You can also use firewire consoles to the same effect, although I've never done that. Once the system panics, it will drop into DDB. I usually kick off debugging by doing a backtrace, bt, and showing the status of the current and then all processors show pcpu, show allpcpu. Depending on the type of bug, I find output from ps, alltrace, show lockedvnods, show alllocks, show uma, show malloc quite useful. The below panic is a NULL pointer dereference in the taskqueue code, but it's likely triggered by a bug in a consumer of the task queue service, rather than the task queue code itself. That means we'll need to identify what consumer that is. That information should become visible by looking at the arguments to the stack trace in DDB. If not, we may need to work a little harder to get a dump, or set up serial or firewire kgdb to inspect the live running system with a full debugger. On the swap / dump / etc thing. In order to capture a saved kernel dump, you need sufficient room for the full dump on whatever partition /var/crash is on, and it must be writable. Because dumps are normally written to swap partitions, running fsck before the dump is captured can lead to portions of the dump being overwritten if fsck uses a lot of memory (and hence overflows into swap). As many systems have a separate /var and /var is often small, it could well be that you can successfully capture the dump by just booting to single-user, manually fscking /var, mounting /var, and running savecore in the /var/crash directory. You can also configure additional partitions as purely dump partitions, rather than swap partitions. One trick I've used previousy is to add a disk temporarily just for the purposes of dumping to, and manually doing a dumpon for a partition on that disk (but not a swapon).

Re: Bash script to find out the summary of user memory usage [not working]
On 2007-12-17 06:00, Patrick Dung [EMAIL PROTECTED] wrote:
I have correction with the script but still doesn't work:

There are *many* race conditions in that script. For example, there's
no guarantee that once you get a snapshot of the ps -A -o user output,
then the same users will be listed in the loop you are running for each
username.
The script is also a bit 'sub-optimal' because it calls ps(1) and parses
its output many times (at least as many times as there are users). A
much better way to `design' something like this would be to keep a hash
of the usernames, and keep incrementing the hash entry for each user as
you hit ps(1) output lines.
I'm not going to even bother writing a script to use a hash in bash(1),
because there are much better languages to work with hashes,
dictionaries or even simple arrays.
Here's for example a Python script which does what I described:
1 #!/usr/bin/env python
2
3 import os
4 import re
5 import sys
6
7 try:
8 input = os.popen('ps xauwww', 'r')
9 except:
10 print Cannot open pipe for ps(1) output
11 sys.exit(1)
12
13 # Start with an empty dictionary.
14 stats = {}
15
16 # Regexp to strip the ps(1) output header.
17 header = re.compile('USER')
18
19 for line in input.readlines():
20 if header.match(line):
21 continue
22 fields = line.split()
23 if not fields or len(fields) 4:
24 continue
25
26 (username, mem) = (fields[0], float(fields[3]))
27 value = None
28 try:
29 value = stats[username]
30 except KeyError:
31 pass
32
33 if not value:
34 stats[username] = 0.0
35 stats[username] += mem
36
37 # Print all the stats we have collected so far.
38 keys = stats.keys()
39 if len(keys) 0:
40 total = 0.0
41 print %-15s %5s % ('USERNAME', 'MEM%')
42 for k in stats.keys():
43 print %-15s %5.2f % (k, stats[k])
44 total += stats[k]
45 # Finally print a grand total of all users.
46 print %-15s %5.2f % ('TOTAL', total)
It's not the shortest Python script one could write to do what you
describe, but I've gone for readability rather than speed or
conciseness.
Running this script should produce:
$ ./foo.py
USERNAME MEM%
_pflogd 0.10
daemon 0.00
bind 1.10
_dhcp0.10
keramida38.60
smmsp0.10
root10.10
build0.00
TOTAL 50.10
$
PS: Yes, you could probably do the same in bash, with sed, awk and a bit
of superglue, but I prefer Perl and/or Python for anything which
involves something a bit more involved than simple string substitution
these days...

Guessing at false positives based on what I see in my inbox (I'm the heaviest mail user on my network), about 10% are probably false positives. 25345/187560 = .1351 = 13.51% of email gets past greylisting. ((3806*.90)/25345) = .1351 = 13.51% of that email is considered Spam, which is probably correct. Based on those numbers, 162,215 messages were probably Spam. I'm guess it's Spam, as none of our users have complained that there is legitimate email failing to get through to their inbox. That would be ~88.8% of email hitting my systems is Spam. I would consider greylisting in my case VERY successful. What this doesn't take into consideration, however, is that I truly hate the delay of receiving a message from someone that isn't in the database, and as such, we're working on improving our SA rulesets and getting rid of greylisting.

Re: Suggestions please for what POP or IMAP servers to use

There's nothing wrong with writing an extremely strict standard. The issue is the implementation. If your server implementation is so strict that most clients have difficulty, then users will find something else and your standard will end up on the dustbin. It's better to start out with a strict standard and a forgiving server implementation, then as it falls into mainstream use, work with the client developers to correct their stuff. You've effectively described dovecot here. No, I haven't. Its codebase is perhaps designed to be very strict, however the same codebase also includes configurable 'workarounds' (enabled by default in many distros) for clients that are not up to spec. They're trivial to toggle and well documented. If you download and compile dovecot then is the default config template that is shipped with it enable the workarounds? No. The excuse that enabled by default in many distros is merely an excuse. Nobody who is serious about building a server for a lot of clients is going to be using some precompiled version, they are going to compile from source so that if a security hole is discovered they can patch it immediately. They're also going to actually *look* at the configuration and tailor it. What kind of fool goes to the trouble of building his own software without also customizing the configuration to his specifications? IF the switches DISABLED the lax behavior, and the defaults in the config templates were to not have the switches triggered, then it would meet the definition of a forgiving server implementation. But it doesen't even go that far. So, this meets both criteria that it will just work with clients now, and the clients themselves could theoretically (good luck with Outlook) fix their code in the future. Outlook works just fine in IMAP mode with uw-imap, both regular Outlook and Outlook Express. I never said it doesn't. Dovecot works fine with Outlook and Outlook Express too (both IMAP and POP3). Imagine that, IMAP servers that successfully service IMAP clients. As far as I'm concerned, it's a fairly ideal environment, It is good you spell out that this is your personal ideal. and I'm glad the developer has gone to the trouble to 1) stick to standards in the core code and 2) made a point of documenting and providing workarounds for buggy clients. It is a lot of extra work to encapsulate all the alleged bugs in separate code so you can provide switches for stick-up-their -asses-admins to flip. That is work that should have gone into speeding up the code. It is utterly wasted effort unless your goal is to allow admins who have penis envy the ability to jerk people around for their choice of e-mail clients. It isn't the mailserver administrator's business if Joe Idiot User who doesen't know any better chooses to use Outlook 97 as an IMAP client, to deny Joe Idiot access to the mailserver. The admin does not need to be playing silly games like this, setting up his server so that only some clients can work with it, others can't, then telling people their software of choice has bugs and fuck you, don't use it. Programmers jobs are to makes things work for users. If Mickeysoft's programmers cannot write a decent IMAP client, then if the developer of an IMAP server can write around the problem, then he should do it and embed the fix in the server code without calling it out in a config switch. The situation is absolutely no different with hardware drivers. Take a look at for example the comments in the ne2000 (ed) driver code, or the DEC/Intel 21143 network card driver code (or man page) There are a number of very badly borked up hardware implementations of those network chipsets. Yet, do the driver authors of the ed or dc driver make the admins flip switches in the driver to make the driver work with their particular borked-up chipset implementation? No. They write the driver code to work with all implementations, even the borked up ones. The dovecot author is engaged in technopolitics. It is a very bad thing to do. Whether the authors of bad IMAP client software deserve this is beside the issue. You need to understand that the ONLY lever that the Open Source community has to keep the giants like Microsoft paying some kind of attention to published standards so that everyone's stuff can interoperate, is the moral superiority lever. In other words, the Open Source community simply does not engage in predatory, circle-the-wagons, use-my-stuff-or-else behavior. We have

ipfw rules for all interfaces not working ...

That's easy. The problem is, this is a laptop and so sometimes iwi0 exists and sometimes it doesn't, and sometimes xl0 exists and sometimes it doesn't ... and that is why my ipfw rules look like this: 00010 00 allow ip from any to any via lo0 00020 00 deny ip from any to 127.0.0.0/8 01000 18134 10505749 allow tcp from any to any established 04000 149884280 allow icmp from any to any 0400127 1728 allow tcp from any to any dst-port 22 setup 04008 00 deny log logamount 100 ip from any to any recv all 65535 15202 2569754 allow ip from any to any See - in rule 04008, I say to deny ip from any to any recv all - so that no matter what interface(s) I have up, and no matter what their addresses are, this one deny rule will apply to them.

Please enlighten me as to why I am wrong: I don't understand why everyone insists on POSIX compliance for portability with shell scripting. The POSIX common demoniator seems to suck. Seriously. One keeps seeing things like: if [ x$var = xvalue ] When the intent is: if [ $var = value ] Because there is presumably some wonky script out there that breaks on the former (or perhaps its POSIX, dunno). I have recently began to appreciate that all this madness that would normally be considered unforgivable code obfuscation in anything but shell scripting, is all an attempt to somehow be portable. In any number of situations I would consider it much preferable to juse choose one particular shell and stick to it, rather than having to do battle with all these minor incompatibilities. Many major shells are very portable to begin with, and in many situation you *REALLY* don't care about some exotic Unix platform that 10 people in the world run, but where bash/zsh/whatever doesn't. Another example of the madness is: http://www.netbsd.org/docs/pkgsrc/makefile.html Check out section 12.3.3. Can anyone claim that it is sensible for it to be this fricking difficult *to print the value of a variable*? Although that last bit has to do with more than the choice of a shell, it highlights perfectly the type of trouble you run into when you try to be portable with the least common denominator. -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller [EMAIL PROTECTED]' Key retrieval: Send an E-Mail to [EMAIL PROTECTED] E-Mail: [EMAIL PROTECTED] Web: http://www.scode.org signature.asc Description: This is a digitally signed message part.

For some reason i like it better than bash, the vi mode is a bit better somehow, it feels alot sturdier.

Re: csh programing book
Well, I was only giving my personal opinion. I've never used irb, but it seems to me that using any sort of OO tool as a shell would be cruel and unusual, but I guess it takes all kinds, and I certainly wouldn't prevent you from enjoying yourself, same as I'd expect from you to mine. The OO nature of it really really does not come into play here as far as I can tell. Whatever you can imagine with perl/python/your-favorite-language is very likely as much possible, if not more so, with Ruby. Certainly if writing something elaborate it comes into play, but then we are away from the shell aspect of the discussion. Doing: system myfile does not become any more obnoxious just because myfile happens to be an object in a well-defined class-based object system. Nor does the function definition: def myfun(param) ... end Become obnoxious just because Ruby happens to be OO, for some definition of OO. My main concern is syntax. I would love to have a shell based on Ruby, Lisp, or some other powerful language (anything that at least allows functions to return values other than status codes... please). But I have yet to find one that makes it maximally simple and efficient to do the common stuff that you use interactively - which is to run external processes. scsh (Scheme Shell) comes pretty close; I have no objection to using it for shell *scripting*. Neither might Ruby be an issue with sufficient API support. But I am not sure about using it interactively. When interactive, you don't want to type even a single annoying character more than you have to. Or at least I don't. That said, scsh might be possible to tweak sufficiently. It actually manages to combine the power of Lisp with the convenience of shell scripting pretty well (as always, by using macros). So you have pretty low-overhead syntax like. For example, instead of: more myfile You have: (run (more myfile)) If you imagine an interactive mode where a top-level (run (...)) would be implied (under certain circumstances), you could make that be exactly equivalent to the normal shell version: more myfile This is true even with parameters; the macros are such that you need not explicitly make them strings (so (run (ls -l /)) is valid for example). I especially like the integration as soon as you want to do something slightly intelligent. E.g.: (run/strings (mystuff --list-something /path/to/db)) Yields an actual list of strings (one per line) that you can touch, pet and otherwise have your way with even if you want to do something other than piping it to the next process. Not to mention having higher order functions at your fingertips... In short, I would just love to have a single language for both tasks, not having to switch from one to the other after some threshold of script complexity. Unfortunately scsh has some issues (e.g., freebsd port is marked as broken om amd64 right now), so I dunno about counting on it being available everywhere. -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller [EMAIL PROTECTED]' Key retrieval: Send an E-Mail to [EMAIL PROTECTED] E-Mail: [EMAIL PROTECTED] Web: http://www.scode.org signature.asc Description: This is a digitally signed message part.

See if the sound server is running. KDE uses aRts, gnome uses esd,

Yes, the arts daemon is running and the esd isn't. Logged in as

To the entire list: be very careful about upgrading right now.

What about using cdcontrol to play a cd? If your cd-rom drive's hooked
up to the audio port on your motherboard, it should skip anything in
FreeBSD and go from hardware to speakers. It might help track down the
problem.

Nothing. I thought I'd get something fromm the -v flag;
nope.
,player, and eeverything else thinks in playing, but the error

There stderr's are probably trace from the pcm/newpcm driver, but
what cauuses them is the mystery.
Also, did you upgrade OSS? OSS uses /usr/src so if you've also done a
csup of /usr/src that doesn't match what's installed it's possible you
got something screwy to happen.
No, but I did a src upgrade tonight and did a make buuildworld. I am
upgrade things that were up-to-date. Should finish by late morning.
Meanwhile, if anyboody know how I fouled things up, please yell at me.

Oh, if you get BEL, you're better off than me for that. I get all of
my sound to work except for BEL!

Re: SSH through port forwarding
Make sure the ISP is not blocking port 22. If they block it, you will need to change the SSH port in sshd_config and then set the router to forward the port to the server's internal IP address. It's a good idea to change the port anyway, in order not to be obvious to script kiddies. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Now, I'm in Idaho and he's in NY (which does make things difficult). Is there any special tricks to setting up port forwarding for SSH? Probably should have checked this first, but I'm going to go look on the handbook too, just to see. It should Just Work(tm). I don't have one of those handy, but port forwarding is generally under the Advanced tab Linksys routers. It may be called Games or something like that. Forward port 22, ssh, to the internal IP and save the settings. Generally one should have a fixed internal IP for forwarding as DHCP assigned IP addresses may change. once you open port 22 to public ip, you'll get people try to bruteforce your machine. if you don't want that set sshd to listen to a higher number like 5522 then forward port 5522 from the router to the internal machines. unfortunately for wrt54g, you can't forward port 5522 to 22 for internal machine. sham khalil ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
