Re: Mail server in that environment, possible ?

One of those is an OpenBSD (4.1) system which I've been happily running an Apache/PHP/MySQL and a FTP server on for a few months. Now, what I would like to do, just for the fun and hopefully to learn a few things in the process, is whether it would be possible to setup a mail server on it so people can send me mail at [EMAIL PROTECTED], and if so, I'd much appreciate if someone could point me to a few nice tutorials to set this up - I've already googled for that and tried a few howto's but without much success. although this is not a typical topic for [EMAIL PROTECTED] Well, it's called misc@ for a reason. It's also called misc@openbsd.org for a reason, but this person uses OpenBSD, so why not? Deep apologies from my side; however, the threshold of when a topic starts to be a valid one here fluctuates extremely. one day, a malfunctioning browser on a OBSD box is not a valid one, while on the other day someone mailing from the highway who run out of gas (but has OBSD running his home brew MP3 player) *is* a valid one... first, you have to get yourself the skills to set up a MTA (mail transfer agent) such as sendmail (included in OpenBSD base system), or postfix (packages/ports), or exim... IMHO, you should take 'the hard way' and learn sendmail Everyone has his/her own preference here. There are no really wrong choices, though. (At least not for simple setups.) 'IMHO' second, you need a POP3 and/or IMAP4 server; there's a bunch of them (packages/ports, again) like dovecot, cyrus, etc. for me, cyrus works like a charm for many many years now Again, no really wrong picks. Dovecot is secure, easy to configure, and fast, but doesn't handle concurrent mailbox access very well, and you might need/want some of the additional options of cyrus. You can also do without an IMAP server if so inclined; particularly the older *NIX mail clients will happily read their mail from a spool. Especially if you prefer such a client, making sure the MTA is set up properly before even trying to set up the IMAP server is a good idea. Depending on tastes, you might also want to set up a webmail package. I can recommend Hastymail for not sucking. (It's not particularly shiny or full-featured, but it manages not to suck, at least to the extent that webmail can not suck. Mutt still sucks less, though.) third, you have to get some knowledge about the appropriate DNS entries (the MX entry for your domain, even when using DynIP services) you have to set. again, there's tutorials on the net. Certainly. And note that this isn't going to work particularly well if you switch IPs often (or at all). The problem is that DNS updates take a while to reach every corner of the internet (and very, very long to reach some broken MS-based setups). If another user takes your IP address in the meanwhile, and that other user also runs something on port 25, MTAs sending you mail will think it's you. In almost all cases (those where no account has been configured to collect all mail), the other mail server would permanently reject mail to you, since there's no such user at that mail server. This would cause random mail loss. For this, one can use the mentioned VPS. four, please take into account that sending from your own mail server being in a dynamically assigned IP range is a bad idea because most RBLs (realtime blackhole lists, used by other MTAs to check whether your MTA is likely to be a spammer or not, etc) list those IP ranges as very likely to be a spam source. so, if possible, use your ISPs mail server for relaying (as a 'smart host' in sendmail speak), or get yourself a machine at a rack hoster; there are decent priced 'virtual root servers' nowadays. (unfortunately, most of them are Linux machines; virtual root means that you're put into a container, or 'jail' like environment, where you are root and can set up that machine as you like; however, you don't have 'full control' over the hardware, but this is not needed anyways.) The whole virtual private server thing has the added advantage of having a fixed IP address, which solves the problem I described above. Exactly. Unless you want to go for a VPS or some such, I'd not recommend running an MTA on port 25. It *is*, however, quite useful to set up fetchmail or one of the alternatives to feed mail to a MTA, and use that MTA to handle outgoing mail. It's doable without those hassles just by defining the MTA as the primary MX which then is configured to relay

OT: SIP termination alternative
Hi, Anyone can recommend a good SIP termination provider, specially for International calls. Domestic US is also needed, but not as badly. I am using Level(3) already and the connection speed is definitely not great all the time and Masergy works well, however to many failed connection is busy day. Many tries are needed in a very short of time to get a connection. The provider could also be based in Europe as well as long as they can work with US company and use SIP. Feedback would be appreciated. This is for volume calls. You can reply in private as well as I am not sure it's of interest for the list. Thanks Daniel

nfe0 problem (obsd 4.1)
Hi, I've been noticing some strange problems with the built-in nfe0 interface on my desktop. Actually I've seen it on two such computers, but the description below is for my current desktop PC. The PC is running `cvs up -dP -rOPENBSD_4_1' built. I'm including netstat, ifconfig output[1] and dmesg below[2]. I've noticed that once in a while the nfe0 interface will stop sending and receiving data. At this point I can not make it work again. The only solution I have is to reboot the box. I have installed a dc0 card in the box since. The problem seemed intermittent and not reliably reproducible. But I think I found a way to reproduce this problem on demand (at least for the time being). I have an ssh session to another box, on which I run '/usr/bin/nm somelib.so'. After a page or two of output the terminal hangs. At this point nfe0 becomes unresponsive. I switch to the dc0 interface and the terminal finishes the output. Running the nm command while using the dc0 interface doesn't cause any problems. Interestingly enough, if I redirect the output of nm to a file and subsequently cat the file the nfe0 interface doesn't seem to exhibit the same problem. I am not sure how to diagnose this problem further. I've enabled debug on the nfe0 interface (/sbin/ifconfig nfe0 debug), but don't see any output.

carp + mysql replication: failover
have two machines that are carped and have mysql databases on them. one machine is the mysql master and the other a slave that replicates the master. this keeps things ready for what i've just experienced: mysql master machine goes down. now that a master failure has occurred, i am not certain of the best path for bringing the master back online so that it's synced with the slave. to bring the master back online correctly i see the following as an obvious, but laborious, path: (1) restart master and increase advskew on the carp interface so the slave stays MASTER (2) edit config files and restart mysql on both machines so that the slave is now the master and vice versa for the original master (3) initiate slave replication onto the original master (4 - optional) decrease advskew on the original master machine so that it takes over (5 - optional) restart mysql on both machines, swapping the master and slave configs. the optional steps are only if restoring the original master as master is desired. if there is another way to do what i've described above that doesn't involve downtime for mysql or is more easily automated, please advise. cheers, jake

Is it possible that load average off by 1 on Sun V100 X1?
I am not sure how to proof this, or to verify for sure, however, doesn't matter what version of OpenBSD I install, or 3.3 up to 4.1 Nothing running and plain install I always get a load average in top, or uptimne to be ~1.15 +/- on either Sun V100 or X1. However, I get ~0.07 on V120 and T1. Doesn't look like it's a specific processor issue, but I don't know really. X1 off by 1: hw.model=SUNW,UltraSPARC-IIe @ 500 MHz, version 0 FPU V100 off by 1: hw.model=SUNW,UltraSPARC-IIe (rev 3.3) @ 548 MHz, version 0 FPU V120 OK: hw.model=SUNW,UltraSPARC-IIe (rev 3.3) @ 648 MHz, version 0 FPU T1 OK: hw.model=SUNW,UltraSPARC-IIi @ 440.039 MHz, version 0 FPU is there a way to see that for sure somehow? Or isolate this more closely? I have multiple one of each and they all give the same results. Is it possible that somehow the representation always add 1 in these cases? Not a big deal, but always wonder where that can possible comes from and why. Obviously it's been there for many years, so not that of a big deal. Best, Daniel

Re: nfe0 problem (obsd 4.1)
On Sunday 24 June 2007 13:50, patrick keshishian wrote: Hi, I've been noticing some strange problems with the built-in nfe0 interface on my desktop. Actually I've seen it on two such computers, but the description below is for my current desktop PC. The PC is running `cvs up -dP -rOPENBSD_4_1' built. I'm including netstat, ifconfig output[1] and dmesg below[2]. I've noticed that once in a while the nfe0 interface will stop sending and receiving data. At this point I can not make it work again. The only solution I have is to reboot the box. I have installed a dc0 card in the box since. The problem seemed intermittent and not reliably reproducible. But I think I found a way to reproduce this problem on demand (at least for the time being). I have an ssh session to another box, on which I run '/usr/bin/nm somelib.so'. After a page or two of output the terminal hangs. At this point nfe0 becomes unresponsive. I switch to the dc0 interface and the terminal finishes the output. Running the nm command while using the dc0 interface doesn't cause any problems. I experienced similar problems last year and can empathize. The following items improved my situation somewhat: 1) BIOS upgrade 2) Removing dual boot (I had both OpenBSD and Windows 2003 on one machine. There were more errors if I did not power off after shutting down Windows 2003 and just did a restart from within Windows. If I did not unplug the machine after shutting down Windows, most of the time I saw watchdog timeouts but if I powered off the host, and then powered it back on, there were fewer errors) I experimented with different combinations and different switches (10/100/1000, 10/100, and 10-Base-T). When all the hosts connected to a 10/100 switch were running at 100 MB/s then changing nfe0 from autoselect to full-duplex using ifconfig nfe0 media 100baseTX mediaopt full-duplex seemed to eliminate nfe0 hangs as well as timeouts completely. I am not sure whether this has any rational basis or is specific to some weird situation in my network, but that has been my experience.

Your guess is correct: OpenBSD only supports the default locale, C.
To quote the source for the strcoll() function:
int
strcoll(const char *s1, const char *s2)
{
/* LC_COLLATE is unimplemented, hence always C */
return (strcmp(s1, s2));

Re: cannot enable executable stack...
As it turns out, this bug in compat_linux was encountered in NetBSD in
2005 and then fixed. The NetBSD patches are
I have successfully ported the relevant material from the NetBSD patches
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/compat/linux/common/linux_misc.c.diff?r1=1.140r2=1.141
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/compat/linux/common/linux_mmap.h.diff?r1=1.16r2=1.17
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/compat/linux/arch/i386/syscalls.master.diff?r1=1.61r2=1.62
to OpenBSD. The OpenBSD patch is given at the end of this message. Be
sure to run the make file at
/usr/src/sys/compat/linux/
after applying the patch. The make file will update some important files.
This patch allows OpenBSD to use the PROT_GROWSUP and PROT_GROWSDOWN flags
to mprotect under Linux emulation. I have tested this new functionality
with the Linux version of the Mathematica 6.0 Kernel, which now runs
successfully. Presumably, OpenBSD will also be able to run other Linux
applications that use these flags, such as Adobe Acrobat Reader (for which
the NetBSD patches were originally intended).
What steps need to be taken to ensure that this fix is merged into the
official OpenBSD source code?
