Re: [gentoo-user] Trouble with portage
You have several issues here. First of all, a tip: If a portage upgrade is available, do emerge portage first. New versions of portage often have new or improved features - in this case portage 2.1.6 includes, among other things, the ability to automatically handle most blockers. The blocker says that gamin 1.10 is blocking the gamin-server 1.10 package. This looks to me like gamin has been split into multiple parts or renamed. portage 2.1.6 should handle this block automatically. On to your next issue where 2 versions of firefox are being pulled in. First of all you need to remove the package.mask entry you added, since it masked out all versions of firefox above 2.0.0 - that includes both firefox 2 and firefox 3 - not particularly useful. The correct resolution here is not obvious. You need to edit your /etc/make.conf and set -firefox xulrunner. This is because a core piece of the mozilla framework, on which firefox is built, called xulrunner has been split out from the firefox package. This will help to avoid issues in the future and allow for faster upgrades. This change should get all applications using firefox 3 instead of firefox 2.

Re: [gentoo-user] wpa_supplicant with madwifi partially stopped working after remerge
Now the modules do correctly (I suppose) create the needed devices and the init scripts pull the interface up. But the boot messages complain about not having set WEP-Keys, which are set in the config file residing at /etc/wpa_supplicant/wpa_supplicant.conf. That results in my WLAN is associated to an unsecured access point in my area. I solved my problem. After the initial and working configuration for wpa_supplicant I also installed the wireless-tools. It was simply curiousity about the user interface of the latter. Sadly I forgot to unmerge it after playing around. Since the wireless-tools are preferred over wpa_supplicant by default the next boot tried to use the unconfigured wireless-tools. Greetings Jan

I actually don't mean to speed up squirrelmail and PHP. The main function of that system is to run a website in perl, and I thought I might be bogging down apache2 a bit just by opening it up to PHP interpretation (-D PHP). Is that the case? It would also be nice not to be exposed to PHP exploits. It just seems kind of silly to maintain and run PHP just for webmail. You could try running a second webserver instance for the webmail, allowing the main one to run without PHP loaded. RobbieAB. signature.asc Description: PGP signature
Re: [gentoo-user] Restricting Firefox website access
I think you would do well to setup a squid proxy and block outbound traffic for the affected machines. We've had great success with squid in our environment. This gives you a tremendous amount of flexibility on your access control, and it means you don't have to be concerned about which transport methods are used when updating/installing. Added bonus is that the squid caches your Gentoo download objects. Is that tough to set up? I would think an iptables solution would be easier, but maybe that won't work out. Well, you'll end up using iptables anyway right? If you really want to -force- folks to get out through a proxy, that is. Since you mention that the router is a gentoo box, should be an easy one. Tough to setup Squid? Naw. Of course, it's like most things, we don't know much about your network or the scope of your requirements. For our use case, we needed the following: -forced access through the proxy -website URL blacklisting and custom redirection based on massive regex lists --Automated notification on certain 'violations' -user account login to the proxy before internet access -username tied to all proxy logs -'manager' access to log data via nifty graphs on a web server So, ours took some time. :) Ya, I know these folks were uuber paranoid, and wanted the ability to nab folks for what they felt like was inappropriate internet usage... Anyway your situation sounds much simpler. So simple in fact that just a few tweaks to the default squid.conf can provide you with a functional config. There are heaps of doco out there on configuring Squid, so you should have a look and see what you think. You can easily get a little test proxy going on a desktop or laptop to try it out. :-) Hope this helps! -- Matt
Re: [gentoo-user] Microphone not working
The microphone on my laptop isn't working and I'm not sure how to troubleshoot it. I've tried using it in twinkle and arecord but it doesn't work in either. The headset works fine on a different system. Can anyone help with this? Chipset of the audio card? Laptop model? It's one of those built-in intel-hda cards and the laptop is an Acer. The mic actually used to work. We have the same problem then! I had a laptop Acer (now it's my girfriends') Aspire 5720G. After a kernel upgrade the mic stopped working. So far I had no luck. My girlfriend just bought an external microphone (she's more pragmatic than me) and that worked. Sorry I'm not able to help. You guys might need to specify your specific model of hda-intel in /etc/modprobe.d/alsa since it may not be auto-detecting the capabilities of which chipset your laptop has. For example on my desktop I added this line: options snd-hda-intel model=6stack-dig Please read the kernel module documentation for a large list of hda-intel chips and configurations. Hopefully you can find one that works for you (if that has anything to do with it). /usr/src/linux/Documentation/sound/alsa/ALSA-Configuration.txt good luck :) Paul Thanks Paul. I've been using model=acer and I just tried a couple others, some worked some didn't. I also tried removing and replacing my second USB sound card definition. The strange thing is I've come back to my original config and it's working now. Could another file have gotten out of order and my playing with the settings got it back together? - Grant

[gentoo-user] nfs failing to start
I've apparently forgotten whatever little I may have know about setting up nfs from having used it long ago. I found a brief help page on google that I used to get this far along at: http://linux-bsd-sharing.blogspot.com/2008/09/howto-setup-nfs-server-on-gentoo.html Its very brief and has no debugging info. Also I see nothing about debugging in /etc/conf.d/nfs either. After setting all nfs related kernel items and booting the kernel. Checking that mods appears to be installed and running. Making sure portmapper is running. Then when I try to start nfs service if it fails. Producing these messages in syslogd: Jan [...] nfsd[29077]: nfssvc: Protocol not supported Jan [...' : RPC: failed to contact local rpcbind server (errno 5). Only one of the nfssvc lines appear but the RPC line appears several times. I got the impression from google that nfssvc was related to nfs4 so may not mean too much ... but not sure.

[gentoo-user] [cifs] permissions of mounted share
Note this is a cross post here and debian.user.. the server is gentoo the client is debian. It's kind of a phony cross post though since I didn't think to do this until I'd already posted on debian user... So its really a second post with the same content. Some consider that a phaux paux(?)... So please forgive with my explanation. Content: I'm using samba and cifs to mount a certain directory on a linux (gentoo) machine (Which will also be accessed by windows machines [but not yet]). On the server machine I've created the directory `projects'. With permissions 755 and ownership reader:wheel This is mounted from a machine runnning debian lenny like this in fstab: (wrapped for mail at the `\') (Note the host name is reader .. not to be confused with user reader) //reader/smProjects /projects cifs noauto,username=reader,\ credentials=/etc/samba/CifsCredentials,uid=reader,gid=wheel OK, with /projects share mounted on the deb machine, I attempt to copy a directory (oneA) of files into it with `cp -a oneA /projects' Note that the same user reader in group wheel exists on both server and client machines. The permissions on oneA (on client) are 755 and the files inside are 644. When I attempt to carry out the copy action I get a slew of warnings like this: cp: setting permissions for `./oneA/...': Permission denied The cp is still carried out but all the files now have 744 permissions. If I drop the -a[rchive] flag and do the cp with `cp -R' its done silently but the permissions still end up 744 on what are regular files (that were 644) Any regular files I create on the mounted share end up 744. Can I set a umask in the mount syntax or what do I need to do here to have the files keep the standard permissions? Why are they being changed?
