 Posted: Mon Aug 13, 2007 9:16 pm Post subject: Precompiled Linux (Debian Etch) PowerPC binaries-release |
 |
|
UPDATED
I have compiled (for fun) static cores on a Debian Etch running on an emulated PowerPC system.
These cores have been tested with success.There are few issues on linkstation's boxes (cause libc/library differences) which could be solved using a trick explained below.
My binaries are been tested with success on these boxes:
Synology DS207 , DS-207 , DS106 , DS-106, DS210+
PCI NAS-01G NAS, similar hardware as the Allnet ALL6250
IOmega OpenCenter 250G NAS
DreamBox DM500
I have build a collection of cores with different configure options, in a single giant archive:
THESE ARE CORES COMPILED ON DEBIAN ETCH, THE BUNDLED LIBRARIES HAVE BEEN UPDATED TOO(for guys using LD_lib trick I suggest to update them too).
Last 3.1.3CVS
Only native code version is provided
All the cores are here (new hosting thanks to ygrek):
http://fabtar.ygrek.org.ua/
Qnap NAS installation:
Qnap users has an alternate and easier mldonkey installation, they should use the automated QPKG pakage management (new firmwares):
http://www.qnap.com/pro_features_QPKG.asp
http://www.qnap.com/faq_detail.asp?q_id=461
Let's choose the release tarball which fits your needs in subfolders!
The archive contains a lot of directories, inside these directories there are complete ready to use mldonkey's tarballs.
These tarballs have various features, there are heavy cores with all the fetures bundled in, and light cores with minimal features for tiny boxes.
You have to choose the core which fits your needs!
full
Enabled networks:ed2k-bittorrent-directconnect-FileTP
Library disabled:none - SUI enabled
normal

normal_gd
Enabled networks:ed2k-bittorrent-FileTP
Library disabled:libmagic - SUI enabled
minimal

Library disabled:Libgd,libmagic - SUI enabled
libraries This archive contatins my own needed libraries.(for static core too)
This is about the compilation enviroment & version:
| Code: |
Compilers:
- Ocaml version 3.12.0
- gcc version 4.x.x
- g++ version 4.x.x
|
mldonkey CVS source has been patched in order to force UTF8.
Please TEST these cores, and give me suggestions-feedback.
Hope useful.
fabtar
IMPORTANT NOTE(linkstation users?).
Mlnet.static still needs a bunch of shared libraries.
In case you are experiencing DNS resolution or libraries problems, I have added my libraries to the archive (there are sometimes libc problems or lacking libraries).
THERE ARE 2 WAYS TO SOLVE DNS PROBLEMS
1)
I have added my needed shared libs in the main archive.Copy them in(example) /new_libs_path
I suggest to create a little script which sets this enviroment variable first to call mlnet (Thanks Georg for testing!):
| Code: | LD_LIBRARY_PATH=/new_libs_path:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
/path_to_mldonkey/mlnet.static |
(*I think*) This starts the static linked mlnet after setting the LD_LIBRARY_PATH environment variable as needed. And the variable is only set for the call of mlnet, thus the remainer of the installation is not affected.
This will luckly cause to first call my libraries first of your ones.
This is an hard hack, it is better to use only when you have reserved a users for mldonkey's sake.
Another command in order to obtain the same result:
| Code: | | LD_LIBRARY_PATH=/new_libs_path:$LD_LIBRARY_PATH ./mldonkey_path/mlnet (arguments?) |
2)
You can also try launching mldonkey chrooted, providing my libraries: http://mldonkey.sourceforge.net/Chroot
for linkstation's users Togeis's chroot walkthru:
http://forum.nas-central.org/viewtopic.php?f=19&t=3682&st=0&sk=t&sd=a&start=30.
P.s.: I think these cores should work if you have a debian linux.
For NO-DEBIAN users, if you have problems
please look at this libraries in your system:
| Code: |
/lib/libresolv.so.2
/lib/libnss_dns.so.2
/lib/ld.so.1
/lib/libc.so.6
/lib/libnss_files.so.2
|
If these libraries has different names on your system, you can try to create symoblic links with these names pointing to your current ones.
for example could be: /lib/ld.so.1 -> /lib/ld.linux.so.3
P.s2: I suggest to test SUI feature, in case you are unsure about the feature is working right or not you can simply disable it by option.

@ZeusII
Thanks for feedback!!These things make me happy!!!
I have seen you have not enabled ed2k network, could you please active ed2k network in order to check if SUI is working well?
Have you a debian release on your box or a specialized distro?

I enable ed2k on demand (only when I need to download something there). How do I check that SUI is working well?
I tried downloading a highly seeded elink and on eMule clients it says Identification: Successful. Are you referring to this?
I'm using the default Synology distro. |

Right, you have done right, SUI identification is there and working.
I have a last request for you:
please execute:
| Code: | | lsof -P -T -p MLNET_PID |
I like to see if you mlnet.static is using shared libraries and how they are named&located on ppc.

Also, (this was happening whit 2.8.7) i'm getting sometimes the following error and the core just closes:
| Code: | 2007/08/16 15:20:26 Exception (socket failed: Too many open files) before connect to host *.*.*.*:2710
|
Do you know how to fix it? maybe compiling whit some option enabled, maybe in the configuration of the client or just downloading less things at the same time? |

Don't know for sure, please post output of mldonkey command: "voo changed", post output (from you box's Linux shell) of command "ulimit -a" .

I have to think about this, I have thought something is opening too much connections/file descriptors.
Let me think on this a bit.I'll post few suggestions on this thread later.

I think your box i creating too much connections,
how many mlnet processes are you running at same time?(normally one ) are you sharing files with your Nas in a enterprise with lot of users?
Have you other services which creates lots of connections?
My idea:
Perhaps you simply eat up all your connections_sockets/file_descriptors.
Lets go deeper...
First let's see something about your system activity an kernel hardlimits, paste the output of (while you are in normal activity, normal usage, normal mldonkey activity):
| Code: | | cat /proc/sys/fs/file-nr |
explanations:http://www.netadmintools.com/part295.html
The only way to solve this issue (first you have to verify the hard limits imposed by your kernel) is to increase the number of file descriptors with
| Code: | | ulimit -n NumbeOfDescriptors |
(please wait a bit for your output to be analyzed first)
Plus you can decrease a bit the max number of connections and max number of connections/sec of your mldonkey.
Last questions:
How much files are you sharing with mldonkey?
How much users are accessing your box at same time?
P.s: I have noted max_hard_download_rate=0. I don't know if this limit bounds control communications too.
Perhaps you can left little 1-2Kbyte/sec of donwload (to be safe&sure)

Well, actually I have three mlnet processes at the sametime (with consecutive PIDs, being everyone a child from the other)
this nas is merely for my personal home usage, so there's not to many simultaneous connections.
I don't have this file: /proc/sys/fs/file-nr
I think that the problem maybe resides in that at this moment I'm downloading 21 files at the same time and seeding 5 more xD |

It's normal 3 mlnet processes, but I am interested in the number od mlnet istances.
Another try, this is not so precise(could be 40% more than real value) but try this:
post output.
I think you have currently 1024 max file descriptors, I think you can raise it by using ulimit -n **** command.

it could be interesting to test with:
lsof | grep MLNET-PID | wc -l
I suppose this command could point the number of file descritors opened by mlnet.
The overmentioned is only for curiosity, I think that the solution are always:
use:
ulimit -n 2048 (from root, 2048 is an example,1024 is the usual value)
and decrease mldonkey connections.
Cheers
P.s: 1600 , your result is not too high.This is the reason I think 2048 could suffice (hoping there is no kernel hardlimit)

mldonkey pid result: 147 at this moment.
I deleted some downloads, I'll see if the error strikes back, and if it does, I'll try with ulimit. Since this started when I added a lot off downloads, I supose I excedeed my nas limit ^^*
Update: I'm going to restart my NAS as it's been 25 days since last reboot and maybe it's a little estressed  |
