On my system it is twice as fast as reiser3 for _lots_ (200.000) of small files with compression on (didn't test is without compression). I didn't test if with big files. But your results may vary anyway. For example btrfs is very cpu-intensive (even more with compression). If you've got a slow cpu (like in embedded devices), jfs might perform better.

[gentoo-user] Sniffing / analysis of application / wifi packets on my LAN
Hi there, I'm interested in the activity of an application which is running on my LAN, and was wondering if anyone could offer some quick pointers on the best tools for this these days. I've played with this some years ago, but only very superficially - I think I used wireshark back then. Ideally what I want to do is capture a big dump of the traffic over a couple of minutes (so it shouldn't be that much, right?) into a file and then analyse it afterwards based on destination IP, content &c. A couple of minutes should allow completion of at least 2 or 3 separate interactions with the server. The network is mine, as is the device from which I'm capturing the data. I have a Belkin F5D7010 wifi card, which I think is based on a RaLink rt2x00 (rt2400 / rt2500) chipset, and I have my network's WPA key, so I think I can just set the wifi card in passive mode for sniffing. I'm pretty sure I experimented with this card in passive mode before, some years ago. Alternatively, I think I can plug the wifi access-point into my PC, bridge it to a second wired NIC and sniff what's going across the bridge (but I don't think this should be necessary). What I'm expecting to see is some image, audio & html files &/or xml data transferred, and ideally I'd like to be able to extract it all and view it in its original format. There's likely to be some inevitable other activity on the wLAN whilst this is happening - I'll try to minimise this, but I think the tools should be able filter out any crap I'm not interested in, right? I'd prefer as much as possible to use CLI tools for capturing / analysing the data. Thanks in advance for any quick pointers you can offer, Stroller.

I have somewhat of a suspicious that `acmkdir' may be just a shell script? (Never used it, so I don't know.) If so then you can just find it on your system and copy it to /usr/local/bin or something like that (it possibly copies the templates from somewhere else, so you will need to find those also).

You misunderstand. The option works just fine and does (correctly) what it is supposed to do. Not all software's build systems out there plays nicely with parallel compiles. ooO for instance is really finicky about it. You can't blame portage for stupid coding errors that other people make, or stupid configurations that you make. -- alan dot mckinnon at gmail dot com

It supports both capture and display filters, so you can limit it to just what you're interested in. If the client and server are both on your LAN, then you should probably go ahead and capture everything, and then use a display filter to limit it to just the hosts you need. That way, if for some reason you find you need to see what else is going on on the network at a given time, the captured data is still there, you just broaden the display filter. As far as CLI tools go, sorry, I'm not sure what's available. Never had a need to look into those. But Wireshark uses libpcap, and digging a bit shows tcpdump, which is a CLI tool that uses libpcap to capture data, so it may give you the same functionality. I've never used it though, so I can't help further. Jake Moe
Re: [gentoo-user] Sniffing / analysis of application / wifi packets on my LAN
Wireshark - always use the latest ~x86. Can capture and save with a lot of options. to just do a quick capture, try "tcpdump -i eth- -w file.pcap" writes a pcap format file (can be read by wireshark etc) "tcpdump -r file.pcap" to see whats in it "tcpdump -A - -r file.pcap" to extract text like html If you already have wireshark, "tshark" can do similar operation to tcpdump.

By passive I assume you mean promiscuous? Since you prefer CLI you can use tcpdump and tcpflow. tcpdump will place your card in promiscuous mode - if you only want to see what's addressed to your machine use the -p switch. To avoid truncating the packets increase the size of the packets captured e.g. -s 65535 and also add some detail -XX to see the payload. Altogether something like this should work: tcpdump -i wlan0 -e -l -U -vvv -s 65535 -w tcpdump_cap.txt -XX (switch -w for -r to read what you've captured). You can use the -T option to only capture/read a particular protocol. I rarely specify this. tcpflow -i wlan0 -c -p -s -v With tcpflow you can specify the protocol (e.g. proto arp) to capture only particular packets as well. Hope this helps. -- Regards, Mick

[gentoo-user] Copying a file via ssh with no password, keeping the system safe
Hi list, I need to set up a cron job to transfer a file every day from server A to server B. I'd like to do that via ssh and with no user assistance, completely automated. Setting up a public key, would do the job, but then, all the connections between the servers would be passwordless, so if server A gets compromised, also server B is screwed. Is there a way to allow only one single command from a single cronjob to operate passwordless, while keeping all the other connections secured by a password? Thank you in advance for your help.

[gentoo-user] Beyond-Gentoo question
Hi, for a long time I have compiled makehuman from the svn tree. This works with no problems with my 32bit Gentoo linux. When changed to 64bit Gentoo Linux it does not work any longer. The compilation itssself is clean, buth the executable does not work as exspected... >From the developpers forum I know that makehuman is 64bit aware and runs (for others, not for me). They also said, that it may have be something to do with the SDL lib. I searched for differences of the installation of SDL between the two systems but I did not found anything -- at least nothing which would alarm me. When makehuman is started it prints on the console: No antialiasing available, turning off antialiasing. No 24 bit z buffer available, switching to 16 bit. No 16 bit z buffer available, exiting. I have no problems with other SDL-related executables. Blender (for example) is heavily using OpenGL and DRI and wirks fine under 64bit Gentoo linux. The output of glxinfo was sent to the developers of makehuman and they did not find anything suspicious. May be someone here on this mailing list is able to point me into the right direction to fix this ? Thank you very much in advance! Best regards, mcc

You could create a user on server B called backup, a user with very limited permissions and no shell (/bin/false). Thus server A can transfer files to serverb:~backup but if the key is compromised then little else can be done. Not sure if the user could somehow be run in a chrooted ssh, for better security? I'm not sure what files a new user "backup" would have read-access to by default? If the key is obtained from server A then the attacker could copy files from server B (back to wherever they like), and it might be possible to obtain information about what services are run on that system or otherwise learn vulnerabilities from what could be read.

In the authorized_keys file, you need to include a specification of "command=". Which means that on log-in with the public key, the sshd will execute that command, and any other commands sent from the machine which originated the connection will not execute. So I'd imagine you can untar with the command at the target, and instead of scp, use something like tar | ssh -i u...@host (of course, this still opens up the possibility that a partition gets filled on your target machine by someone copying random string to it, but you'd have to live with that). (Also, note, I haven't actually tried this method of copying files myself, so while I'd imagine it'd work, you may need to play around with it for a bit. What I've done before was to have a shell script set to run, triggered by a public key login like this.) See 'man sshd' for more detail. HTH, W -- Willie W.

Well, not really... public key authentication works on a per-user basis, so all you get is that some user with a specific key can log in as some other user of B without typing a password. Of course, if you authorize a given key for logging in as r...@b, then what you said is true. But that is a problem with the specific setup. > Is there a way to allow only one single command from a single cronjob to > operate passwordless, while keeping all the other connections secured by > a password? You can't do that on a per-command basis. You'd be trying to control the authentication method accepted by sshd on B according to which command is run on A -- something sshd on B knows nothing about. I would try the following way: - Set up an unprivileged user on B -- let's call it foo -- which can only write to its own home directory, /home/foo. - add the public key you will be using (*) to f...@b's authorized_keys file. You should set the key's options to 'pattern="",no-pty,command="/usr/bin/scp -t -- /home/foo"' (man sshd for details). - chattr +i /home/foo/.ssh/authorized_keys, so that the file can only be changed by a superuser (you can't just chown the file to root as sshd is quite anal about the permissions of the authorized_keys file) Now your cron job on A can do "scp f...@b:/home/foo" without the need for entering a password; you just have to set up another cron job on B that picks up the file from /home/foo and puts it where it should go with the correct permissions, possibly after doing a sanity check on its contents. If you use something else than scp, (e.g. rsync) you should also adjust the command option in the key options above. Note that the option refers to what is run on B, not on A. Also, it is *not* an authorization directive à la /etc/sudoers (i.e., it does not specify what commands the user is allowed to run): it simply overwrites whichever command is requested by the client side of the ssh connection, so that, for example, the client cannot request a shell or do "cat ". (*) You can either use the key of the user running the cron job on A, or generate a separate key which is only used for the copy operation. In this case, you will need to tell scp the location of the private key file with the -i option. HTH, andrea

Going along with what Alan said. qt3support does not use Qt 3 at all. It just puts something like a Qt 3-compatible API into Qt 4, to make porting Qt 3 to Qt 4 apps easier. It is largely insignifcant to you (since it's not pulling in qt3 packages). If you have any packages that require this USE flag, their ebuild will require this USE flag. So disable it, emerge --deep --newuse world and see if it complains. If it does, re-enable and continue life with qt3support as if nothing ever happened. :)

Add the following line to your kernel parameter list: raid=noautodetect md=3,/dev/sda1,/dev/sdb1 root=/dev/md3 the first parameter on md= is the number of the md node. So if you want it as /dev/md3, you specify the 3. The RAID level is automatically detected. Other then that: Make sure the mdm subsystem is really compiled into the kernel and not a module.

[gentoo-user] Uploading Files to Windows CE
Does anyone know how to upload files from a Gentoo box to Windows CE? The CE device has a cradle with a usb connection which appears as character device in /dev/ttyUSB0 . The Windows cetools / cecopy does it if you want to use Windows. However, I would like to do it from Gentoo if possible. Any ideas? Thanks, dhk
Re: [gentoo-user] Copying a file via ssh with no password, keeping the system safe
Quoting Andrea Conti : On 07/10/2010 18:45, Momesso Andrea wrote: Setting up a public key, would do the job, but then, all the connections between the servers would be passwordless, so if server A gets compromised, also server B is screwed. Well, not really... public key authentication works on a per-user basis, so all you get is that some user with a specific key can log in as some other user of B without typing a password. Of course, if you authorize a given key for logging in as r...@b, then what you said is true. But that is a problem with the specific setup. Is there a way to allow only one single command from a single cronjob to operate passwordless, while keeping all the other connections secured by a password? You can't do that on a per-command basis. You'd be trying to control the authentication method accepted by sshd on B according to which command is run on A -- something sshd on B knows nothing about. I would try the following way: - Set up an unprivileged user on B -- let's call it foo -- which can only write to its own home directory, /home/foo. - add the public key you will be using (*) to f...@b's authorized_keys file. You should set the key's options to 'pattern="",no-pty,command="/usr/bin/scp -t -- /home/foo"' (man sshd for details). - chattr +i /home/foo/.ssh/authorized_keys, so that the file can only be changed by a superuser (you can't just chown the file to root as sshd is quite anal about the permissions of the authorized_keys file) Now your cron job on A can do "scp f...@b:/home/foo" without the need for entering a password; you just have to set up another cron job on B that picks up the file from /home/foo and puts it where it should go with the correct permissions, possibly after doing a sanity check on its contents. If you use something else than scp, (e.g. rsync) you should also adjust the command option in the key options above. Note that the option refers to what is run on B, not on A. Also, it is *not* an authorization directive à la /etc/sudoers (i.e., it does not specify what commands the user is allowed to run): it simply overwrites whichever command is requested by the client side of the ssh connection, so that, for example, the client cannot request a shell or do "cat ". (*) You can either use the key of the user running the cron job on A, or generate a separate key which is only used for the copy operation. In this case, you will need to tell scp the location of the private key file with the -i option. HTH, andrea Thank you all for your fast replies, I think I'll use all of your suggestions: -create an unprivilegied user with no shell access as Stroller and Andrea suggested -I'll setup a passwordless key for this user, only limited to a single command, as Willie suggested This sounds pretty sane to me.

You should file a stabilisation request at b.g.o. they are likely not in testing because there's something wrong with them, they are probably in testing because nobody has bothered bumping them to stable. However, considering the speed that Google are releasing Android versions, I think that the usual gentoo arch/~arch methodology is a bit of a joke in this case. If you didn't use the ebuilds, you'd be installing the latest sdk from google anyway, right? All the ebuild does is unpack a binary archive into /opt, nothing magic there, no real compelling need to wait for a stable version. And it doesn't need any ~arch deps either I say just be done with it, keyword the damn thing and install it. -- alan dot mckinnon at gmail dot com

I didn't want to remove it and recompile just to find out KDE won't work anymore. That would be . . . bad. lol I need to put me a backup WM on here just in case KDE does go belly up at some point. At least I can run a browser and look for help. Dale :-) :-)

But I would still have to recompile again with the qt3support flag if it messed up badly. On this machine, that takes time. During that time, I may not have KDE at all. I did that when I made a mistake a while back. About 12 hours with no GUI. That was with some packages being binary and using -k. If I have to recompile them all, it would take longer still. Not something I want to repeat. Dale :-) :-)

Handy if you want to capture to a file on a unix based firewall or F5 etc so you can then view it in Wireshark on your workstation. > So Wireshark is a GUI tool? > Yes. It has crypto decode for SSL if you have the private key, so it might also be possible to have it decode WPA since you have the key - RTFM to find out for sure. Depending on how the crypto works you may need to have captured the beginning of the crypto setup to be able to decode, as that's where the session key will be exchanged. Cant remember if WPA does that or not.
