How to build lint libraries, e.g. llib-lc.ln?
Hi folks, when writing C applications I'd like to check them using lint. Unfortunately FreeBSD comes with only "llib-lposix.ln" and "llib-lstdc.ln" in "/usr/libdata/lint". Is there an easy, i.e. automated, way to create lint libraries (e.g. llib-lc.ln) for all the libs in "/usr/src/lib"?

I halved the MAX_SPAWN_RATE to 16 (from 32) and then *exactly* the same thing happened; it only took a minute longer to happen If i recall correctly (not sure anymore since it was middle of the night) other processes also got blocked (hence i couldnt use keyboard anymore). That was why i figured it was some kind of lock/block/mutex/whatever inside the kernel Best Regards, Ali Niknam ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Is this definitely > true, that UMAllocing in special zone is faster than general malloc()? Allocating from a zone was noticeable for gige interfaces, especially on my SMP configuration (which was running w/o Giant). For non-gige interfaces the overhead of using malloc is not noticeable (as I reported when I first converted vlan handling over to use tags). Regardless the point was that you can already use a zone for tags if you want.

patch to add additional devices to uftdi(4)
I couldn't find a maintainer for uftdi(4), so I sent the patch in as a PR. It is available here: http://www.freebsd.org/cgi/query-pr.cgi?pr=67357 It adds support for the Intrepid Control Systems USB based vehicle bus interfaces. Earlier, I submited a PR that contains a patch that should be ignored (a subset of the later patch), but also a bug that results in a system panic. A USB and/or uftdi person might want to take a look at it: http://www.freebsd.org/cgi/query-pr.cgi?pr=67301 mike ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Network config on FreeBSD 5.1 - Help!
As what have been pointed out, It may help if you comment out the lines in rc.conf as below: #ifconfig_vr0="inet6 hex address netmask 255.255.255.0" ipv6_enable="NO" #hostname= "..." #ppp_enable="YES" #ppp_mode="ddial" #ppp_nat="YES" #ppp_profile="bellnet.ca" sendmail_enable="YES" gateway_enable="YES" rpc_statd_enable="YES" tcp_extensions="YES" hostname="..." ifconfig_vr0="DHCP" Since your modem is taking care of the PPPoE stuff, you don't need "ppp" on your freebsd. Comment them out. Now as root, you can do the following: # /stand/sysinstall Then choose menu: "Configure" => "Networking" => "Interfaces" => "vr0". Then select: "No" for IPV6 if you don't want IPV6; "Yes" for DHCP; "hostname.yourdomain.com" for host; "yourdomain.com" for domain; Upto this point, if your DHCP server (should be on the DSL modem which usually is bundled with a router) is working, you should have seen other information like "Gateway", "name server", "IPV4 address" and "netmask" shown on the screen. Simply press "OK". If no error message seen, your network MUST work now. You dont' even need to input the IP address, netmask, DNS server blah blah... The DHCP server will populate you with such information. To find out whether your DHCP server is on, get the IP addresses of your two XP machines by running "ipconfig" on a DoS prompt, which will tell you the IP address and gateway IP (also the DHCP server IP). The IP addresses of your two XPs should have the same subnet. i.e., the first two or three bytes are often the same (like 192.168.0.x). Last, make sure your Ethernet cable is not broken and your modem and hub are powered on when you'r configuring. Check whether the lights on both the hub and freebsd machine is on. A reboot often helps too. Wish it helps. --- aussie gal wrote: > This is the set-up: > > I have a High-Speed Internet connection. What you > would call a DSL modem connection.
