iSCSI on a ZyXEL NAS?

[MrDini]

No, I Can also build the stable version, that you linked without any errors. But before that, I used a beta source, which gived e some strange errors, as You Can see at my past messages...

You can think whatever you want, but that doesn't make you right

Nice sentence, I have to learn that! But in this case, not true, because I already checked my thought wit readelf and it consolidated me. See:

Code: Select all

root@NSA320S:~# readelf -a /ffp/lib/libc.so.0 | grep 'fmemopen'
root@NSA320S:~#

I have theese uClibcs installed:

uClibc-0.9.33.3_git-arm-5
uClibc-solibs-0.9.33.3_git-arm-5

[barmalej2]

What are you trying to convince? That the C library lacks standard functions ?
Below is the output from extracted uClibc-solibs-0.9.33.3_git-arm-5 package:

384: 00034dac 268 FUNC GLOBAL DEFAULT 7 fmemopen

Ah surprise again -fmemopen is not hidden and available

[MrDini]

I tried to install Your latest uClibc which not supports UTF-8 characters:

Code: Select all

root@NSA320S:~# readelf -a /ffp/lib/libc.so.0 | grep 'fmemopen'
   384: 00031738   268 FUNC    GLOBAL DEFAULT    7 fmemopen

And with downgrade to the UTF-8 supporting:

Code: Select all

root@NSA320S:~# readelf -a /ffp/lib/libc.so.0 | grep 'fmemopen'
root@NSA320S:~#

[barmalej2]

fmemopen function is available in uClibc if not from the beginning of it, then at least from 2003y for sure. And it doesn't depends uclibc has UTF- support or not.

And with downgrade to the UTF-8 supporting:

Ok. Let's do it:

Surprise, surprise I have libc, which has and supports fmemopen function.

[MrDini]

Yes, very interesting. I wanted to share for You the package, that I am used, but I already found one at my repo, I hope that is the "wrong" package without fmemopen:

http://users.atw.hu/mrdini/packages/nee ... -arm-5.txz

Many thanks for the link, I will try it.

Mod: hurray, hurray! I owe a particular debt of gratitude for You!

Yahoo! The main compilation also done (open-iscsi)... I just have to correct the pathes to fit to the FFp.

Code: Select all

I am a bit shocked According to this your comment:viewtopic.php?f=249&t=14977&start=15#p103831 I was thinking that you already using updated versions of uClibc.

[MrDini]

Yes, sorry. But I had to update the uClibc to a non UTF-8 build for testing. And after it I reinstalled the UTF-8 build. But for that, I have an alias called uclibc-utf8, which reinstalled the old packages.

[MrDini]

Okay, So I Could built the package as I already wrote earlier and now, I finished wroting configure files and editing the pathes to fit to the FFp...

But, when I try to start it, certainly it gives me an error :

Code: Select all

iscsid: can not bind NETLINK_ISCSI socket

I googled that, and some people think, that is a selinux error, but I don't think So and hope also, that isn't a selinux error...

[barmalej2]

Do the problem persist after reboot?

[MrDini]

Good idea!

But not works in that case... The error msg is exactly the same.

[barmalej2]

Strace?

[MrDini]

Here is a strace output.

Ps: yes, I mistyped the strace at the paste title...

[barmalej2]

159.access("/etc/iscsi/", F_OK) Do this directory really exists? Can you specify path to config manually using iscsid command line args?
Has iscsid option to disable logging to syslog?

[MrDini]

Ahh, sorry, for the strace, I forgot to run with some plus options... Here is the correct output.

Has iscsid option to disable logging to syslog?

Unfortunately, not. But it is not necessary I think.
