Re: [gentoo-user] kernel BUG when unplugging usb?

When I plug them back in, they don't work! I just tried to unload reload usb-hid, but modprobe locked up on the reload. It appears the only way to fix it is to reboot. This happens with tuxonice sources 2.6.23-r9 but never happened with 2.6.22.* or earlier. That bug is known (search with google), it's a race condition because of proper locking in the kernel in the evdev code. It's fixed in 2.6.24.

First, what card and which drivers? 01:00.0 VGA compatible controller: nVidia Corporation NV15 [GeForce2 GTS/Pro] (rev a4) I have nvidia drivers version 71.86.01 running now. I also re-compiled xorg-server, with vanilla gcc, GLX is running fine again, and I am happy. I have an old card that is not supported by drivers = 1.0.9700, so ... scratch that, I didn't notice that the versioning scheme changed. http://www.gentoo.org/doc/en/nvidia-guide.xml they refused to compile telling me that this would do more harm than good with a hardened setup. I put them into packages.unmask, now they compile and the nvidia module loads, but still X has no GLX, xorg.0.log says Failed to initialize GLX extension (NVIDIA X driver not found), This really does not sound like a hardened issue... I need to upgrade my drivers to the 96.* to see if I can reproduce your problem, but with 1.0.8776 (from two years ago) I definitely do not have your problem. Maybe I'll try again with hardened then. My experience with nvidia is that that it makes LOTS of trouble. This, and VMware, often made kerned updates a real pain for me. I often got those errors before, with the desktop profile, on different machines. glxinfo segfaults. I guess I will try to re-compile all X stuff with the vanilla gcc. glxinfo segfaulting is expected. Do you have chpax/paxctl installed? No, not yet. I must admit I do not know much about hardened yet, but I want to play around with it and get some experience, so I started with preparing the setup by setting the hardened profile and switching to a hardened kernel. I have my entire system on the hardened profile (including X and nvidia [yes, despite the warnings of the hardened team about nvidia]) and no problems. My guess is that your problem with GLX lies somewhere else. That's good to hear! So I will stick with hardened. Would it be possible to make these changes permanent, that is, can I tell portage to compile specific packages with a specific compiler? /etc/portage/package.compilerflavor or something? Don't know. On the wiki there is a way to switch CFLAGS, don't know if something like that can be used to strip SSP and/or PIC flags from the hardened. I don't find this information there, I guess I did not look hard enough. But there is /etc/portage/bashrc, I can put a little script in there, stripping those flags for the given packages.

You can google for that to learn what it means. There are two ways to speed up KDE load time. First, prelink everything (something like prelink -avmR). Second, you can configure kdm to preload as much of KDE as possible. So while you are still staring at your login screen or typing your user name and password, it loads as much as it can. BTW, KDE 4 starts significantly faster than 3.5. Uwe -- Informal Linux Group Namibia: http://www.linux.org.na/ SysEx (Pty) Ltd.: http://www.SysEx.com.na/ -- gentoo-user@lists.gentoo.org mailing list

Re: [gentoo-user] Linux, reiserfs and file fragmentation
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, just one more idea that came to my mind, reiserfs uses a technique to save small files in the filesystem tree which uses less disk space then. In ext3 a 1 byte file will take up 4k, while this is not the case in reiserfs. This yields a performace hit of about 5% (people say, not that i have measured anything) If you have enough free space you can disable this, make the small files consume more space again and gains some speed improvement. Another thing you could do is disable the writing of accesstimes. Read man mount how to do this. The mount options are noatime,notail. Concerning your observation I would start looking at how the fragmentation is measured. Maybe this also depends on the filesystem implementation in the kernel. Anyway: you can not get much better 1.043.. parts per file. This means that almost every file(96,12 % in your case) is contiguous. have fun | | | I did a little test. Something fishy here.

If you have a movie with 30MB fragments, then it is no problem. Unless you hear lot of rattling noise from the HDD, you could leave it as is. And the surest way to defragment a filesystem is take everything out and put it back again. It will write the files one after another and will have no reason to split them. So if for example I copied everything over to a different hard drive and then copied everything back, it would be defragmented then? I would think of something like this: Boot some live CD. Mount old and backup drives. Copy old drive to a backup drive using cp -av yada yada. Make a new file system on the old drive to make sure all is clean.

[gentoo-user] slightly OT, laptop for gentoo
Hey all, I need a laptop. But the requirements are slightly odd. This is for a machine to stay in our colo cage for use as a barcode scanner, serial interface, basic GUI, and ssh server management console, etc. It needs to have USB for an eToken, PS2 for a barcode scanner, serial to manage PDUs KVM etc, on-board ethernet, and not be flimsy, big, or expensive. Obviously we can easily get a USB to serial adapter, meaning we'd need at least 2 USB ports, but a PS2 keyboard port seems a rarity now-a-days. Battery life isn't really important. Doesn't need to be a properly ruggadized, just sturdy. 15 or so screen, with a decent resolution to fit webpages and OO documents etc, 17 is too big. 512-1G of ram, so-so CPU (this P4M 1.8 I'm using is way more than powerful enough). Can anyone recommend a laptop that does all these things, runs Linux happily (Gentoo of course), and isn't a Thinkpad (I was forced to use one a few years ago, and hated it).

Yea, I have always read that Linux file systems are a lot better at
taking care of fragmentation. Considering how old this install is and
how much has been installed/removed/upgraded over the past several
years, I think it is not to bad really. Even 10% with the number of
files I have is better than fat or NTFS. My bro has XP with NTFS and it
gets downright awful.
For the record, I have over 502,000 files and over 49,000 directories on
this system. That's less than 20,000 files that are fragmented. It's
not just the OS but documents, little movies and a LOT of pictures.
Maybe I just need a bigger hard drive. O_O I have two 80GB drives and
a single 40GB drive. Waiting on DSL. he he he he he
I also attached a copy of the program I used. I think I got it off the

Re: [gentoo-user] OpenVPN setup
On Wed, 13 Feb 2008 08:19:48 -0800 Grant [EMAIL PROTECTED] wrote: Even if you just want to encrypt some clear-text protocol that doesn't have an encrypted equivalent, a vpn is still overkill. For that you use ssh tunneling (which is essentially the same thing as an encrypted version of a protocol). 'ssh -X' is the classic example of easily tunneling a protocol that doesn't have a native encrypted equivalent. I see what you're saying. Can tunneling through ssh be made automatic so that a cron job initiates a script that opens a tunnel between the remote server and local print server and pages are printed through the tunnel? Sure. ssh is just a process after all and in principle encapsulated whatever gets put into it. All you need is a connection that isn't firewalled out and an sshd that is listening to what is coming in. ssh will even port forward for you and can be made to transform any tcp connection to appear to come from whatever port you want. What you put inside the tunnel is up to you. If the print server won't accept what is coming in, then google will find you any number of apps that will mangle the traffic. Your statement it seems like running SSH inside a VPN is better for security than running SSH on a non-standard port is non-sensical. From a security and encryption perspective, ssh and OpenVPN are exactly the same thing - stuff wrapped in an encryption layer provided by ssl, complete with exactly the same key setup should you choose to use that route. What about having ssh, imap, smtp, cups, and possibly a non-standard https port all hidden within a VPN? Should that be considered a benefit of running a VPN? I've filed the original post somewhere else and forgot the scenario :-) Is this a setup you need to be present often or even all the time? If so, you have 5 protocols in use, and setting up tunnels could become cumbersome. You might consider that it's more effort than it's worth and a VPN that is there and JustWorks(tm) is preferable. I would call that a sensible use of a VPN :-) I don't think there's a golden rule about when using a VPN is right or wrong. It's more like do the advantages outweigh the hassle of setting it up and maintaining it?. Sometimes this answer is obvious, sometimes less so. Sometimes it's a judgement call. Thanks a lot for everyone's help. Here is a more to-the-point list of what I'd like to accomplish: 1. encrypt CUPS printouts between remote server and local print server 2. add an additional layer of security around SSH and CUPS on local firewall/print server 3. add an additional layer of security around SSH, IMAP, and non-standard port HTTPS on remote server 4. enable access to SMTP on remote server for me which is blocked by my local ISP It sounds like I have 3 choices: 1. VPN 2. SSH tunneling 3. Zebedee tunneling Would all 3 of these choices accomplish all 4 requirements? I would think SSH tunneling can't really add an additional layer around SSH. Encrypted packets, encrypted? Why not? I'd like to have something I can leave up all the time so the services are always protected and I don't have to go through an extra step to use email or print from the remote server. Can all 3 of these be left up all the time? Is there any reason not to leave this type of functionality up all the time? I don't use tunnels, but leave VPN up all the time. It sounds like VPN would be the most difficult to set up and maintain, followed by SSH tunneling, followed by Zebedee tunneling. Maybe I'm wrong though. With tunneling, would I need to set up 4 or 5 different tunnels for CUPS, IMAP, SMTP, non-standard port HTTPS, and SSH (if I'm using Zebedee)? tunnels aren't configured, but would probably have to be created at boot. vpn is, I suppose, not super easy to configure. I will send you my config files though if you want. To send me mail, mail servers need to connect to my remote server's SMTP right? Would setting up a tunnel or VPN for my SMTP access interfere with that? Not if you tunnel through to the right ports - or in the case of a VPN, no. -- gentoo-user@lists.gentoo.org mailing list
