Re: FAQ entry for printing?
On 2014-06-30, Alan Corey alan01...@gmail.com wrote: Could we have an FAQ entry for how to set up printing with lpr and/or cups? I had lpr working once years ago with a text printer. Now I want to print (mostly JPEGs) to an HP color laser printer (cp2025dn). I've got a PPD file I found on the web (it's Postscript) for the printer which has its own IP address. I'm not using color management I don't think but the files I'm trying to print are sRGB. Under Windows 2000 they worked fine but XP added color management so now a purple flower prints blue. I'd like to print under OpenBSD as an alternative. If somebody's got this working and could describe the setup that would be a good start. I'm trying to do photo quality prints which I used to be able to do under Windows 2000. Thanks, Alan The pkg-readme files for CUPS and hplip-common are very useful for getting this setup. /usr/local/share/doc/pkg-readmes/hplip-common-* /usr/local/share/doc/pkg-readmes/cups-*

CARP without IP on the physical interfaces of carp group?
Hi all, in the official CARP/pfsync faq here: http://www.openbsd.org/faq/pf/carp.html I found an information, that suggests that it's possible to use CARP without IPs attached to the physical interfaces used in a CARP group: ipaddress This is the shared IP address assigned to the redundancy group. This address does not have to be in the same subnet as the IP address on the physical interface (if present). This address needs to be the same on all hosts in the group, however. And in this netbsd related guide: https://www.netbsd.org/docs/guide/en/chap-carp.html I found this : ...although with the introduction of the carpdev directive, there is no more need for IP addresses on the physical interfaces. Is it really possible to use CARP without IPs assigned to the physical interfaces? How does the communication between the interfaces of a group work if there are no IPs assigned to them? Which disadvantages could this mode of operation have compared to the classic mode with IPs assigned? (Each and every configuration example I found on the net including those on the OpenBSD site, use IPs assigned to the physical interfaces...) Thanks!

Re: CARP without IP on the physical interfaces of carp group?
Henning, thanks for your quick reply. Which disadvantages could this mode of operation have compared to the classic mode with IPs assigned? the backup node might not be able to reach the network on the carp if Hmm... what does this mean to me..? To make it more precise - my setup looks like this: Physical NIC - trunk interface - vlan interface = physical interface of the carpdev - carpdev - virtual IP (no IP on the vlan interface) I tested this setup and experienced unpredictable transitions from and to master/backup state on different carp groups configured that way and also unstable connections with 50% packet loss. I strictly followed the carp/pfsync configuration guidance in respect of advskew, sysctl.conf options and so on. So I wondered if this may have been caused by the no IP configuration. Is multicast only used when there are no IPs configured for the physical interfaces of the carpdevs?

Re: 5.5 bsd.rd fails to boot on alix
Christian Weisgerber: I vaguely remember that at some point there was a change that requires a new boot(8), otherwise a serial console won't be set correctly with a new kernel. hmmm ... would this affect both pxe and locally booting bsd.rd? It affects both pxeboot(8) and boot(8) on disk. where is this documented? I don't think it is explicitly documented anywhere, but this may be pertinent: Upgrades are only supported from one release to the release immediately following it. Do not skip releases. If you got lucky skipping releases in the past, you may not this time. excellent, copying the updated pxeboot(8) into place was the ticket. as this was not an upgrade, but instead a wipe-and-reload it never occurred to me that the boot(8) blurb in the upgrading documentation would have been relevant. i now understand that pxeboot(8) is just a modified version of boot(8), but still may not have found it myself because i didn't make that connection. thanks for pointing this out.

I strictly followed the carp/pfsync configuration guidance in respect of advskew, sysctl.conf options and so on. So I wondered if this may have been caused by the no IP configuration. Is multicast only used when there are no IPs configured for the physical interfaces of the carpdevs? Not exactly. From ifconfig(8): CARPPEER _peer_address_ Send the carp advertisements to a specified point-to-point peer or multicast group instead of sending the messages to the default carp multicast group. The _peer_address_ is the IP address of the other host taking part in the carp cluster. With this option, carp(4) traffic can be protected using ipsec(4) and it may be desired in networks that do not allow or have problems with IPv4 multicast traffic. So it always uses multicast unless you specify carppeer. Reading ip_carp.c, I don't see any reason carppeer can't be a completely arbitrary address, including an address bound to a loopback adapter. Using carppeer unwisely can defeat the purpose of the multicast transmission, i.e. detecting layer 2 failures, if your layer 3 ensures the carppeer address remains reachable (e.g. both hosts are running OSPF and can re-route over another interface). Recap: - Interface state (carrier/no-carrier) detects local layer 1 failures only - Multicast heartbeat detects layer 2 failures, and remote layer 1 failures; this is desirable in VLAN scenarios, I believe, where carrier/no-carrier does not signify anything useful. - Using carpdev specifies the interface on which to bind the CARP address and on which to send multicast packets. If it is not specified, it is inferred from the subnet. - Using carppeer disables multicast - the nominal use case is to protect CARP traffic with IPSec. Other uses are possible, but questionable because they may break lower-level assumptions. (or so I believe, anyway. I'm sure Henning will correct me if not.) FWIW, I don't use carppeer even though it could save me substantial IP address space, for a couple of reasons: 1) I want the canary-in-the-coal-mine to inform me of any layer 2 weirdness 2) I prefer predictability and normal use cases 3) if I ever stop using CARP and switch to HSRP or VRRP, I'll need those addresses again -Adam

I'm sure Henning will correct me if not.) I don't think carppeer uses than manually specifying the IP on the carpdev of the other node are very well tested, so there might be surprises, but I really don't why other uses shouldn't work as long as the nodes see each other.

Whoops, you're right - I fixed a few errors in my email before sending, but missed those ones. #1 is somewhat valid - using carppeer would prevent me from learning that multicast was broken. I'm not sure how it could ever break on a L2 VLAN, but still... #2 is somewhat valid - using carppeer isn't the typical scenario. Nor is using carpdev, although I have the impression that use of carpdev (and therefore only needing 1 IP address) is increasing. #3 really has nothing to do with carppeer, unless I deliberately used addresses foreign to that interface/subnet, which would probably be silly, but could be another way around needing 3 IPs in the same subnet to implement CARP. Using carpdev is a much more sensible option to avoid IP address proliferation with CARP. -Adam

I consider carpdev that natural use, we're stacking interfaces after all. I even wouldn't be surprised if the !carpdev case bites the bullet at some point, should we change/redesign basics.

I've read a lot about it and it's been sending chills up my spine. The devs are totally unconcerned about how their project breaks others and the language about policing the processes and the users using cgroups to force them to only use X amout of cpu time is, well, dictatorish and promotes laxity in the way of writing your programs and running them to be light on resources. But, like I said, are other people fixing this in a cross platform way, or should I work towards that end? The reason sysVinit is nolonger supported is because it is deemed to difficult to maintain, at least by the opensuse community. Oh, before I forget, the systemd project DOES do one thing and do it well, (they cause problems,) they start and controll all processes on the system. If you read the initial announcement it even mentions that they wish to replace inetd and in later pages they also mention cron as something that they could replace (and at the rate that they are going they will.)
