Fwd: c++11 question: clang++ 3.3 header not found
AFAIK, the easiest way to get C++11 support in clang is to use libc++ (see
http://blogs.freebsdish.org/theraven/2013/01/03/the-new-c-stack-in-9-1/).

There two C++ runtime libraries, the old gcc libstdc++ which is used by
default and the new C++11 libc++. You can use the latter like this:
clang++ -std=c++11 -stdlib=libc++ -otest test.cc

C++11 not working anymore with clang 3.2
Hello there, I've installed the c++ (libc++ library) like this : make -C /usr/src/lib/libcxxrt all install make CXX=clang -C /usr/src/lib/libc++ all install Then, I was able to compile with clang++ using -std=c++11 -stdlib=libc++. And now, after the clang-3.2 update I can't build anymore, I get this error: /usr/local/bin/ld: CMakeFiles/irccd.dir/Irccd.cpp.o: undefined reference to symbol '__cxa_free_exception@@CXXABI_1.3' /usr/local/bin/ld: note: '__cxa_free_exception@@CXXABI_1.3' is defined in DSO //lib/libcxxrt.so.1 so try adding it to the linker command line //lib/libcxxrt.so.1: could not read symbols: Invalid operation clang: error: linker command failed with exit code 1 (use -v to see invocation) *** [irccd/irccd] Error code 1 I've also tried recompiling libc++ and libcxxrt with the last clang++ but it didn't help.

You need /bin/sh in each jail for pkg to be able to workout what ${ABI}
should be.
You need /var/db/pkg and /var/cache/pkg available and writable in the
jail / chroot (ie. relative to the chroot or root of the jail)
That's basically it.
You might run into problems running some package scripts if you're
trying to manage a chroot designed for a very different CPU arch / OS
version than your system is running: this is something we haven't really
put much thought into yet.

Using the new C++11 stack on 9.1
Hello. I was very happy when I received the 9.1 announcement in my mailbox, especially when I read about the inclusion of the new C++11 stack including LLVM libc++ and libcxxrt. So I decided to test it on a 9.1 system: clang++ foo.cc -stdlib=libc++ However, the compilation fails: /usr/bin/ld: cannot find -lc++ It's available in the source tree for 9.1, my assumption is that it's just not installed by default. What should I do in order to use it? I have not found much documentation on it other than it will be the default in 10.

That can be done with the opendir() function; its manpage
lists other interesting "follow-up functions" to work with.

You can use readdir() and parse its output. If you already know
the file name, use a fopen() call for the mode you're trying to
open it with (e. g. "r" or "w") to see if the permissions are
set accordingly. Also ferror() can be used to test for specific
errors that may occur during file operations.

That also sounds possible. In case you're going to continue to
operate with the file in question, certain functions sound better.
But for the "pure testing", access() and stat() provide sufficient
functionality.

which C function is best to check for directory EXISTANCE?
which C function is best to check for the existence of a
*directory*? say that I am want to make postitve that "/tmp/foo/"
exists.
ALso: which will make sure that the directory AND ffile
"tmp/foo/filename12345" exists and that I have read access to it?
in other words, can playing around with access() and stat() be
best? is there any new dirstat("PATh") that would work?
just want to see which way is best?

Unless ZFS is put on a bare, unpartitioned disk, configuration for performance is better left to the user. It's a pain to correct automatic configs when they guess wrong.

It's not about hiding the device's native block size, it's about getting the filesystem to do aligned I/O so the device can just read or write a single 4K block instead of part of one and part of another. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

The process should be correct, but it's new, so there may still be unexpected inaccuracy. As far as alignment on MBR, the trick is to use -a when creating the FreeBSD partitions. MBR slices are aligned to CHS values, pretty much assuring they will not be aligned to 4K boundaries. Using -a4k when creating FreeBSD partitions inside those misaligned slices will make sure the partitions are correctly aligned. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Perhaps in the future FreeBSD will have a blocksize/erase-blocksize aware formatting & partitioning tool(s), but at the moment, you need to make sure those are correctly aligned if you want good performance from 4k blocksize drives (& SSDs will probably still need to be aligned to whatever the erase block size is).

FreeBSD on SSD on ASUS P5KPL-C

There _was_ a recent discussion on 'questions' -- I'm the 'guilty party'
responsible for naming a lot of the 'historical' ones.
That aside, for the OP:
C code generated from C++ will _not_ be very readable.
Basically, -everything- in C++ would get turned into a function invocation
in the generated C. With the _name_ of each such function having an encoded
representation of the type of each argument to that function (see 'function
name mangling). And the "simple" elementary data types tend to end up as
something like: "**struct foo {bar value; (*(**struct foo)baz())[];}".
Some of the mayhem: _everything_ is 'double indirect' pointers, to support
run-time automatic garbage collection; 'methods' of acting on data elements
are pointers to functions, embedded in the data-element structure, even
basic 'four function calculator' arithmetic ops (they can be 'overlaid'
to do differnt things on different data types -- the '+' operator may
mean 'concatenation' when applied to two strings, or '+=' maay mean
'append item to list, in the contest of 'list += item', even though both
would *still* mean 'addition' when used with numeric items.)
One would be far better off spending some time to learn the basics of C++
syntax -- to be able to 'read' the existing code and understand what it's
doing. After that, if what you want to modiy -is- truely a 'minor' change,
adding some 'C-tyee' code to implement it is probably not that bad.

Uninvitedly adding toolbars, changing web browser home page and default search engine are - in my opinion - malicious acts, so the term "malware" may be correct here. Maybe the term "spyware" is also appropriate, depending on what the "additions" actually do behind the curtain. Note an important thing: When careless users will notice the change, they will maybe blame the authors of the original software, not the distributor.

So my question is as simple as that: what is the precise spell to put in make.comf to get (while not disrupting the ports infrastructure!) -march=amdfam10 if compiler is lang/gcc46 and -march=barcelona for path64 (perhaps yet another flags as well if toolchain supports them)?

That's fine, yes. But I wouldn't do an unconditional installkernel after buildkernel (suppose buildkernel failed in some way)? Either include both targets in the same make command: make buildkernel installkernel Or make the second conditional on the outcome of the first: make buildkernel && make installkernel You might also save yourself some time by using "-DNO_CLEAN" after changing your kernel config. -- Conrad J.

With ports, a "make clean" before rebuilding is a good idea. The build might not be able to continue cleanly, or might have to build differently, depending on what was changed. For /usr/src, I just remove /usr/obj/usr and build again, but also use devel/ccache so there's not much penalty for doing that. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

On a slow processor, it makes a *BIG* differnence. Even more so if you build everything you need into the kernel. 'make buildkernel' always recompiles an relinks *everything*. whether or not any dependenies for the module have changed. I've tried 'make buildkernel' on a 'loaded' 486 box, and had it take close to TWENTY FOUR HOURS to complete. With one minor tweak to the config file, e.g. changing one of the 'shared memory' constants, and it is _another_ 24+ hours. *Lots* of it building loadable modules that I have no need for, nor any intention of ever useing. Using the 'old' way, a first-time kernel build was under 40 minutes, and a 'tweak' re-build was under 15. That box is long gone, but on a 733mhz PIII I can go from editing a config file to running on the new kernel in less than 5 minutes (wall clock). The largest part of that time is running 'make depend'. (Second-largest is the rebooting. :) I don't know about anybody else, but _I_ consider that speed differential a *big* advantage to the 'old way'. :) I am likely _not_ the typical user -- I run a monolithic kernel, with everything I need 'compiled in'; *no* loadable modules. Yeah, it can be a nuisance if I need something that isn't compiled in, but I don't get ny unexpected surprises. It also does wonders as far as reducing the required 'root partition' size.

Sometimes, while building process of some port or system kernel are in progress, you suddenly remember that you did something wrong and have to stop, solve your mistake and start one more time. Is it clear to interrupt the building process just by pressing Ctrl + ? If it's so, do I need to run "make clean" before I start "make" one more time?

And, you deserve what happens if you use that kind of flawed checking. :)

I'm not sure this is required. Many functions that deal with
characters (in this case: letters) do operate on (int) instead
of (char). For example getc() and getchar(), but also getch()
from NCurses do so. It's common to simply compare those (int)
value to character constants without casting them to (char)
before comparison.

The advice from my computer-science professor was 'try it and find out'.
It doesn't matter what anybody _says_ it is, the only thing that
matters is what the computer (or, to be precise, the compiler) accepts?
Now, for some information that you could/should get from any elementary
book on C programming ("The C Programming Language", by Kerningan and
Ritchie [r.i.p., this last week] is recommended):
In general, you don't need _any_ explicit casts for those situations.
C does 'automatic' promotion of numeric items so they have comparable
'width' for comparisons.
For more details, see the 'fine manual' mentioned above.

Re: Simplest way to deny access to a class C
The original question had to do with requests to a web server, and it would not be practical nor typical to route all http traffic through inetd. As well, tcpwrappers require manual work; mod_security and fail2ban are both ban automatically based on specified criteria and patterns. While mod_security only works for Apache, fail2ban works for any service that writes out to a log file. We have it watching our instances of Apache, Postfix, Cyrus IMAP, and sshd services for repeated login failure within a short period of time. It has done wonders.

No trying to do anything else, hack or send email So I decided to block the Class C. I guess that with the deny, allow directives under Apache would be enough but they do not work. I am under Apache 1.3x and all works fine but that directives do not. I tried , read and not be able to make them work so that's why I decided to block them and block others, those yes are trying to hack, the simplest way. anyway I will see if the: >hosts.allow / hosts.deny would help. If needed I would upgrade to latest version of FreeBSD Apache or whatever needed. Even when they do not do anything my server, a 386 that has been running Freebsd the last 13 years since Freebsd 3.x is supporting this extra load and besides they are wasting my bandwidth. I can not do anything and no problem but I'd like to solve this and continue learning Freebsd. Thanks for your time.

I guess something simple could work For some reason, don ask me why becasue I did not find why, the: Order Deny, Allow Deny IP Allow all under httpd.conf and outsite as .htaccess does not work but for now teh thing is simple, to block a class C, those guys are stupiod and programmed bad an application (I guess) and are pointing to one of my domains... since 4 weeks ago I am receiving this kind of access: 189.254.19.93 - - [04/Mar/2011:19:43:48 -0600] "OPTIONS / HTTP/1.1" 200 - "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:43:48 -0600] "PROPFIND /Backup-usuarios HTTP/1.1" 301 323 "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:43:48 -0600] "PROPFIND /Backup-usuarios/ HTTP/1.1" 200 40833 "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:44:13 -0600] "OPTIONS / HTTP/1.1" 200 - "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:44:13 -0600] "PROPFIND /Backup-usuarios HTTP/1.1" 301 323 "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:44:13 -0600] "PROPFIND /Backup-usuarios/ HTTP/1.1" 200 40833 "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:44:19 -0600] "OPTIONS / HTTP/1.1" 200 - "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:44:19 -0600] "PROPFIND /Backup-usuarios HTTP/1.1" 301 323 "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:44:19 -0600] "PROPFIND /Backup-usuarios/ HTTP/1.1" 200 40833 "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:44:34 -0600] "OPTIONS / HTTP/1.1" 200 - "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:44:34 -0600] "PROPFIND /Backup-usuarios HTTP/1.1" 301 323 "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:44:34 -0600] "PROPFIND /Backup-usuarios/ HTTP/1.1" 200 40833 "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:45:06 -0600] "OPTIONS / HTTP/1.1" 200 - "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:45:06 -0600] "PROPFIND /Backup-usuarios HTTP/1.1" 301 323 "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" 189.254.19.93 - - [04/Mar/2011:19:45:06 -0600] "PROPFIND /Backup-usuarios/ HTTP/1.1" 200 40833 "-" "Microsoft-WebDAV-MiniRedir/5.1.2600" They change IP's , from the same Class C. No trying to do anything else, hack or send email So I decided to block the Class C. I guess that with the deny, allow directives under Apache would be enough but they do not work. I am under Apache 1.3x and all works fine but that directives do not. I tried , read and not be able to make them work so that's why I decided to block them and block others, those yes are trying to hack, the simplest way. anyway I will see if the: hosts.allow / hosts.deny would help. If needed I would upgrade to latest version of FreeBSD Apache or whatever needed. Even when they do not do anything my server, a 386 that has been running Freebsd the last 13 years since Freebsd 3.x is supporting this extra load and besides they are wasting my bandwidth. I can not do anything and no problem but I'd like to solve this and continue learning Freebsd. Thanks for your time.

Re: Simplest way to deny access to a class C
Check out portsentry perhaps? I used to use it quite a bit. Whenever someone would hit one of a number of defined ports, I'd automatically add a rule denying them in IPFW and also drop their route to a non-existent IP on my class C.

Re: Simplest way to deny access to a class C
fail2ban by default only bans an IP for 10 minutes, and that's configurable. It can also email you anytime it imposes a ban, so one can keep an eye on things at least in the beginning to see if it's causing a problem for legitimate users.

Not > good. Fortunately this is a relatively low risk with fail2ban, because to spoof a failed SSH connection you need to spoof a whole three-way TCP handshake.This could happen, but only if the attacker is on the same subnet as the affected customer or can intercept all their traffic for a man-in-the-middle attack. A bigger risk is customers fat-fingering their password repeatedly and locking themselves out. ;) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
