• Rsyslog is not working properly, it does not log anything

  - by Victor Henriquez

  I'm running a Debian server and a couple of days ago my rsyslog started to behave very weird, the daemon is running but it doesn't seem to do anything. Many people use the system but I'm the only one with (legal) root access. I'm using the default rsyslogd configuration (if you think is relevant I'll attach it, but it's the one that comes with the package). After I rotated all the log files, they have remained empty: # ls -l /var/log/*.log -rw-r--r-- 1 root root 0 Jun 27 00:25 /var/log/alternatives.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/auth.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/daemon.log -rw-r--r-- 1 root root 0 Jun 27 00:25 /var/log/dpkg.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/kern.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/lpr.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/mail.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/user.log Any try to force a log writing does not have any effect: # logger hey # ls -l /var/log/messages -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/messages Lsof shows that rsyslogd does not have any log files opened: # lsof -p 1855 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME rsyslogd 1855 root cwd DIR 202,0 4096 2 / rsyslogd 1855 root rtd DIR 202,0 4096 2 / rsyslogd 1855 root txt REG 202,0 342076 21649 /usr/sbin/rsyslogd rsyslogd 1855 root mem REG 202,0 38556 32153 /lib/i386-linux-gnu/i686/cmov/libnss_nis-2.13.so rsyslogd 1855 root mem REG 202,0 79728 32165 /lib/i386-linux-gnu/i686/cmov/libnsl-2.13.so rsyslogd 1855 root mem REG 202,0 26456 32163 /lib/i386-linux-gnu/i686/cmov/libnss_compat-2.13.so rsyslogd 1855 root mem REG 202,0 297500 1061058 /usr/lib/rsyslog/imuxsock.so rsyslogd 1855 root mem REG 202,0 42628 32170 /lib/i386-linux-gnu/i686/cmov/libnss_files-2.13.so rsyslogd 1855 root mem REG 202,0 22784 1061106 /usr/lib/rsyslog/imklog.so rsyslogd 1855 root mem REG 202,0 1401000 32169 /lib/i386-linux-gnu/i686/cmov/libc-2.13.so rsyslogd 1855 root mem REG 202,0 30684 32175 /lib/i386-linux-gnu/i686/cmov/librt-2.13.so rsyslogd 1855 root mem REG 202,0 9844 32157 /lib/i386-linux-gnu/i686/cmov/libdl-2.13.so rsyslogd 1855 root mem REG 202,0 117009 32154 /lib/i386-linux-gnu/i686/cmov/libpthread-2.13.so rsyslogd 1855 root mem REG 202,0 79980 17746 /usr/lib/libz.so.1.2.3.4 rsyslogd 1855 root mem REG 202,0 18836 1061094 /usr/lib/rsyslog/lmnet.so rsyslogd 1855 root mem REG 202,0 117960 31845 /lib/i386-linux-gnu/ld-2.13.so rsyslogd 1855 root 0u unix 0xebe8e800 0t0 640 /dev/log rsyslogd 1855 root 3u FIFO 0,5 0t0 2474 /dev/xconsole rsyslogd 1855 root 4u unix 0xebe8e400 0t0 645 /var/spool/postfix/dev/log rsyslogd 1855 root 5r REG 0,3 0 4026532176 /proc/kmsg I was so frustrated that even reinstall the rsyslog package, but it still refuses to log anything: # apt-get remove --purge rsyslog # apt-get install rsyslog I thought someone had hacked the system, so run rkhunter, chkrootkit, unhide in an attempt to find hide processes / ports and nmap in a remote host to compare with the ports shown by netstat. And I know this doesn't mean anything, but all looks ok. The system also have an iptables firewall that is very restrictive with incoming / outgoing connections. This is driving me crazy, any idea what is going on here?

• Spacewalk 2.0 provided to manage Oracle Linux systems

  - by wcoekaer

  Oracle Linux customers have a few options to manage and provision their servers. We provide a license to use Oracle Enterprise Manager's Linux OS management, monitoring and provisioning features without additional cost for every server that has an Oracle Linux support subscription. So there is no additional pack to license and no additional per server cost, it's all included in our Basic, Premier and Systems support subscriptions. The nice thing with Oracle Enterprise Manager is that you end up with a single management product that can manage all aspects of your software stack. You have complete insight into the applications running, you have roles and responsibilities, you have third party connectors for storage or other products and it makes it very easy and convenient to correlate data and events when something happens. If you use Oracle VM as well, you end up with a complete cloud portal with selfservice, chargeback, etc... Another, much simpler option, is just using yum. It is very easy to take a server and create directories and expose these through apache as repositories. You can have a simple yum config on each server pointing to a few specific repositories. It requires some manual effort in terms of creating directories, downloading packages and creating local repo files but it's easy to do and for many people a preferred solution. There are also a good number of customers that just connect their servers directly to ULN or to our free update server public-yum. Just to re-iterate, our public-yum servers have all the errata and updates available for free. Now we added another option. Many of our customers have switched from a competing Linux vendor and they had familiarity with their management tools. Switching to Oracle for support is very easy since we don't require changes to the installed servers but we also want to make sure there is a very easy and almost transparent switch for the management tools as well. While Oracle Enterprise Manager is our preferred way of managing systems, we now are offering Spacewalk 2.0 to our customers. The community project can be found here. We have made a few changes to ensure easy and complete support for Oracle Linux, tested it with public-yum, etc.. You can find the rpms in our public-yum repos at http://public-yum.oracle.com/repo/OracleLinux/OL6/. There are repositories for spacewalk server and then for each version (OL5,OL6) and architecture (x86 and x86-64) we have the client repositories as well. Spacewalk itself is only made available for OL6 x86-64. Documentation can be found here. I set it up myself and here are some quick steps on how you can get going in just a matter of minutes: Spacewalk Server Installation : 1) Installing an Oracle Database Use an existing Oracle Database or install a new Oracle Database (Standard or Enterprise Edition) [at this time use 11g, we will add support for 12c in the near future]. This database can be installed on the spacewalk server or on a separate remote server. While Oracle XE might work to create a small sample POC, we do not support the use of Oracle XE, spacewalk repositories can become large and create a significant database workload. Customers can use their existing database licenses, they can download the database with a trial licence from http://edelivery.oracle.com or Oracle Linux subscribers (customers) will be allowed to use the Oracle Database as a spacewalk repository as part of their Oracle Linux subscription at no additional cost. |NOTE : spacewalk requires the database to be configured with the UTF8 characterset. |Installation will fail if your database does not use UTF8. |To verify if your database is configured correctly, run the following command in sqlplus: | |select value from nls_database_parameters where parameter='NLS_CHARACTERSET'; |This should return 'AL32UTF8' 2) Configure the database schema for spacewalk Ideally, create a tablespace in the database to hold the spacewalk schema tables/data; create tablespace spacewalk datafile '/u01/app/oracle/oradata/orcl/spacewalk.dbf' size 10G autoextend on; Create the database user spacewalk (or use some other schema name) in sqlplus. example : create user spacewalk identified by spacewalk; grant connect, resource to spacewalk; grant create table, create trigger, create synonym, create view, alter session to spacewalk; grant unlimited tablespace to spacewalk; alter user spacewalk default tablespace spacewalk; 4) Spacewalk installation and configuration Spacewalk server requires an Oracle Linux 6 x86-64 system. Clients can be Oracle Linux 5 or 6, both 32- and 64bit. The server is only supported on OL6/64bit. The easiest way to get started is to do a 'Minimal' install of Oracle Linux on a server and configure the yum repository to include the spacewalk repo from public-yum. Once you have a system with a minimal install, modify your yum repo to include the spacewalk repo. Example : edit /etc/yum.repos.d/public-yum-ol.repo and add the following lines at the end of the file : [spacewalk] name=spacewalk baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/spacewalk20/server/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1 Install the following pre-requisite packages on your spacewalk server : oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64 oracle-instantclient11.2-sqlplus-11.2.0.3.0-1.x86_64 rpm -ivh oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64 rpm -ivh oracle-instantclient11.2-sqlplus-11.2.0.3.0-1.x86_64 The above RPMs can be found on the Oracle Technology Network website : http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html As the root user, configure the library path to include the Oracle Instant Client libraries : cd /etc/ld.so.conf.d echo /usr/lib/oracle/11.2/client64/lib oracle-instantclient11.2.conf ldconfig Install spacewalk : # yum install spacewalk-oracle The above yum command should download and install all required packages to run spacewalk on your local server. | NOTE : if you did a full, desktop or workstation installation, | you have to remove the JTA package | BEFORE installing spacewalk-oracle (rpm -e --nodeps jta) Once the installation completes, simply run the spacewalk configuration tool and you are all set. (make sure to run the command with the 2 arguments) spacewalk-setup --disconnected --external-db Answer the questions during the setup, ensure you provide the current database user (example : spacewalk) and password (example : spacewalk) and database server hostname (the standard hostname of the server on which you have deployed the Oracle database) At the end of the setup script, your spacewalk server should be fully configured and you can log into the web portal. Use your favorite browser to connect to the website : http://[spacewalkserverhostname] The very first action will be to create the main admin account.

• Finding nuggets in ARC discussions

  - by alanc

  A bit over twenty years ago, Sun formed an Architecture Review Committee (ARC) that evaluates proposals to change interfaces between components in Sun software products. During the OpenSolaris days, we opened many of these discussions to the community. While they’re back behind closed doors, and at a different company now, we still continue to hold these reviews for the software from what’s now the Sun Systems Group division of Oracle. Recently one of these reviews was held (via e-mail discussion) to review a proposal to update our GNU findutils package to the latest upstream release. One of the upstream changes discussed was the addition of an “oldfind” program. In findutils 4.3, find was modified to use the fts() function to walk the directory tree, and oldfind was created to provide the old mechanism in case there were bugs in the new implementation that users needed to workaround. In Solaris 11 though, we still ship the find descended from SVR4 as /usr/bin/find and the GNU find is available as either /usr/bin/gfind or /usr/gnu/bin/find. This raised the discussion of if we should add oldfind, and if so what should we call it. Normally our policy is to only add the g* names for GNU commands that conflict with an existing Solaris command – for instance, we ship /usr/bin/emacs, not /usr/bin/gemacs. In this case however, that seemed like it would be more confusing to have /usr/bin/oldfind be the older version of /usr/bin/gfind not of /usr/bin/find. Thus if we shipped it, it would make more sense to call it /usr/bin/goldfind, which several ARC members noted read more naturally as “gold find” than as “g old find”. One of the concerns we often discuss in ARC is if a change is likely to be understood by users or if it will result in more calls to support. As we hit this part of the discussion on a Friday at the end of a long week, I couldn’t resist putting forth a hypothetical support call for this command: “Hello, Oracle Solaris Support, how may I help you?” “My admin is out sick, but he sent an email that he put the findutils package on our server, and I can run goldfind now. I tried it, but goldfind didn’t find gold.” “Did he get the binutils package too?” “No he just said findutils, do we need binutils?” “Well, gold comes in the binutils package, so goldfind would be able to find gold if you got that package.” “How much does Oracle charge for that package?” “It’s free for Solaris users.” “You mean Oracle ships packages of gold to customers for free?” “Yes, if you get the binutils package, it includes GNU gold.” “New gold? Is that some sort of alchemy, turning stuff into gold?” “Not new gold, gold from the GNU project.” “Oracle’s taking gold from the GNU project and shipping it to me?” “Yes, if you get binutils, that package includes gold along with the other tools from the GNU project.” “And GNU doesn’t mind Oracle taking their gold and giving it to customers?” “No, GNU is a non-profit whose goal is to share their software.” “Sharing software sure, but gold? Where does a non-profit like GNU get gold anyway?” “Oh, Google donated it to them.” “Ah! So Oracle will give me the gold that GNU got from Google!” “Yes, if you get the package from us.” “How do I get the package with the gold?” “Just run pkg install binutils and it will put it on your disk.” “We’ve got multiple disks here - which one will it put it on?” “The one with the system image - do you know which one that is? “Well the note from the admin says the system is on the first disk and the users are on the second disk.” “Okay, so it should go on the first disk then.” “And where will I find the gold?” “It will be in the /usr/bin directory.” “In the user’s bin? So thats on the second disk?” “No, it would be on the system disk, with the other development tools, like make, as, and what.” “So what’s on the first disk?” “Well if the system image is there the commands should all be there.” “All the commands? Not just what?” “Right, all the commands that come with the OS, like the shell, ps, and who.” “So who’s on the first disk too?” “Yes. Did your admin say when he’d be back?” “No, just that he had a massive headache and was going home after I tried to get him to explain this stuff to me.” “I can’t imagine why.” “Oh, is why a command too?” “No, _why was a Ruby programmer.” “Ruby? Do you give those away with the gold too?” “Yes, but it comes in the ruby package, not binutils.” “Oh, I’ll have to have my admin get that package too! Thanks!” Needless to say, we decided this might not be the best idea. Since the GNU package hasn’t had to release a serious bug fix in the new find in the past few years, the new GNU find seems pretty stable, and we always have the SVR4 find to use as a fallback in Solaris, so it didn’t seem that adding oldfind was really necessary, so we passed on including it when we update to the new findutils release. [Apologies to Abbott, Costello, their fans, and everyone who read this far. The Gold (linker) page on Wikipedia may explain some of the above, but can’t explain why goldfind is the old GNU find, but gold is the new GNU ld.]

• Gearman too many processes issue

  - by Roman Newaza

  I use Net_Gearman from PECL, Gearmand 1.1.11 and Gearman Manager. Every time I add background job, I can see new worker listed with no Function, nor Id in Ggearman-Monitor: If I add many messages in the bash loop, after some time it becomes very slow. for i in $(seq 0 9999); do php Client.php && echo $i; done Yesterday, the situation was even worse - I had many error messages in Gearmand log regarding Too many open files and once I added --file-descriptors=49152 as an option and swithched to 1.1.11 from 1.0.6, these errors gone. Here is lsof -p $(cat /var/run/gearman/gearmand.pid) output: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME gearmand 2020 gearman cwd DIR 8,2 4096 2 / gearmand 2020 gearman rtd DIR 8,2 4096 2 /

• Segmentation Fault (11) with modwsgi on CentOS 5.7 when running pyramid app

  - by carbotex

  I'm getting Segmentation fault error when trying to access the "Hello World" pyramid app. This error only occurs when running against CentOS 5.7 setup, but no problem whatsoever when tested against OSX and Arch Linux. Could it be a CentOS specific issue? [error] [client 10.211.55.2] Premature end of script headers: pyramid.wsgi [notice] child pid 31212 exit signal Segmentation fault (11) I have tried to follow the troubleshooting guides posted here http://code.google.com/p/modwsgi/wiki/InstallationIssues which suggests that it might caused by missing Shared Library. A quick check reveals that shared library is not the issue. [centos57@localhost modules]$ ldd mod_wsgi.so linux-gate.so.1 => (0x00e6a000) libpython2.7.so.1.0 => /home/python/lib/libpython2.7.so.1.0 (0x0024c000) libpthread.so.0 => /lib/libpthread.so.0 (0x00da8000) libdl.so.2 => /lib/libdl.so.2 (0x00cd6000) libutil.so.1 => /lib/libutil.so.1 (0x00110000) libm.so.6 => /lib/libm.so.6 (0x0085c000) libc.so.6 => /lib/libc.so.6 (0x00682000) /lib/ld-linux.so.2 (0x0012b000) Then I found another clue that might be able to solve my problem. Unfortunately libexpat is not the source of the problem. http://code.google.com/p/modwsgi/wiki/IssuesWithExpatLibrary [centos57@localhost bin]$ ldd ~/httpd/bin/httpd | grep expat libexpat.so.1 => /usr/local/lib/libexpat.so.1 (0x00b00000) [centos57@localhost bin]$ strings /usr/local/lib/libexpat.so.1 | grep expat libexpat.so.1 expat_2.0.1 [centos57@localhost bin]$ python Python 2.7.2 (default, Nov 26 2011, 08:08:44) [GCC 4.1.2 20080704 (Red Hat 4.1.2-51)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import pyexpat >>> pyexpat.version_info (2, 0, 0) >>> I've been pulling my hair out trying to figure out what I'm missing in my setup. Why the problem only occurs with CentOS? Here is the detailed setup: Apache 2.2.19 Python 2.7.2 mod_wsgi-3.3 /home/httpd/conf/extra/pyramid.wsgi from pyramid.paster import get_app application = get_app('/home/homecamera/hcadmin/root/production.ini', 'main') /home/httpd/conf/extra/modwsgi.conf LoadModule wsgi_module modules/mod_wsgi.so WSGIScriptAlias /myapp /home/root/test.wsgi <Directory /home/root> WSGIProcessGroup pyramid Order allow,deny Allow from all </Directory> # Use only 1 Python sub-interpreter.

• Postfix "warning: cannot get RSA private key from file"

  - by phew

  I just followed this tutorial to set up a postfix mailserver with dovecot and mysql as backend for virtual users. Now I got the most parts working, I can connect to pop3 pop3s imap and imaps. Using echo TEST-MAIL | mail [email protected] works fine, when I log into my hotmail account it shows the email. It also works in reverse hence my MX entry for mydomain.com finally has been propagated, so I am being able to receive emails sent from [email protected] to [email protected] and view them in Thunderbird using STARTTLS via IMAP. Doing a bit more research after I got the error message "5.7.1 : Relay access denied" when trying to send mails to [email protected] using Thunderbird being logged into [email protected], I figured out that my server was acting as an "Open Mail Relay", which - ofcourse - is a bad thing. Digging more into the optional parts of the tutorial like shown workaround.org/comment/2536 and workaround.org/ispmail/squeeze/postfix-smtp-auth I decided to complete these steps aswell to be able to send mails via [email protected] through Mozilla Thunderbird, not getting the error message "5.7.1 : Relay access denied" anymore (as common mailservers reject open relayed emails). But now I ran into an error trying to get postfix working with SMTPS, in /var/log/mail.log it reads Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: cannot get RSA private key from file /etc/ssl/certs/postfix.pem: disabling TLS support Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: TLS library problem: 20251:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:650:Expecting: ANY PRIVATE KEY: Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: TLS library problem: 20251:error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib:ssl_rsa.c:669: That error is logged right after I try to send a mail from my newly installed mailserver using SMTP SSL/TLS via port 465 in Thunderbird. Thunderbird then tells me a timeout occured. Google has a few results concerning that problem, yet I couldn't get it working with any of those. I would link some of them here but as a new user I am only allowed to use two hyperlinks. My /etc/postfix/master.cf looks like smtp inet n - - - - smtpd smtps inet n - - - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes and nmap tells me PORT STATE SERVICE [...] 465/tcp open smtps [...] my /etc/postfix/main.cf looks like smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no append_dot_mydomain = no readme_directory = no #smtpd_tls_cert_file = /etc/ssl/certs/postfix.pem #default postfix generated #smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key #default postfix generated smtpd_tls_cert_file = /etc/ssl/certs/postfix.pem smptd_tls_key_file = /etc/ssl/private/postfix.pem smtpd_use_tls = yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smptd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination myhostname = mydomain.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = localhost.com, localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf virtual_transport = dovecot dovecot_destination_recipient_limit = 1 mailbox_command = /usr/lib/dovecot/deliver The *.pem files were created like described in the tutorial above, using Postfix To create a certificate to be used by Postfix use: openssl req -new -x509 -days 3650 -nodes -out /etc/ssl/certs/postfix.pem -keyout /etc/ssl/private/postfix.pem Do not forget to set the permissions on the private key so that no unauthorized people can read it: chmod o= /etc/ssl/private/postfix.pem You will have to tell Postfix where to find your certificate and private key because by default it will look for a dummy certificate file called "ssl-cert-snakeoil": postconf -e smtpd_tls_cert_file=/etc/ssl/certs/postfix.pem postconf -e smtpd_tls_key_file=/etc/ssl/private/postfix.pem I think I don't have to include /etc/dovecot/dovecot.conf here, as login via imaps and pop3s works fine according to the logs. Only problem is making postfix properly use the self-generated, self-signed certificates. Any help appreciated! EDIT: I just tried this different tutorial on generating a self-signed certificate for postfix, still getting the same error. I really don't know what else to test. I also did check for the SSL libraries, but all seems to be fine: root@domain:~# ldd /usr/sbin/postfix linux-vdso.so.1 => (0x00007fff91b25000) libpostfix-global.so.1 => /usr/lib/libpostfix-global.so.1 (0x00007f6f8313d000) libpostfix-util.so.1 => /usr/lib/libpostfix-util.so.1 (0x00007f6f82f07000) libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0x00007f6f82cb1000) libcrypto.so.0.9.8 => /usr/lib/libcrypto.so.0.9.8 (0x00007f6f82910000) libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x00007f6f826f7000) libdb-4.8.so => /usr/lib/libdb-4.8.so (0x00007f6f8237c000) libnsl.so.1 => /lib/libnsl.so.1 (0x00007f6f82164000) libresolv.so.2 => /lib/libresolv.so.2 (0x00007f6f81f4e000) libc.so.6 => /lib/libc.so.6 (0x00007f6f81beb000) libdl.so.2 => /lib/libdl.so.2 (0x00007f6f819e7000) libz.so.1 => /usr/lib/libz.so.1 (0x00007f6f817d0000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f6f815b3000) /lib64/ld-linux-x86-64.so.2 (0x00007f6f83581000) After following Ansgar Wiechers instructions its finally working. postconf -n contained the lines as it should. The certificate/key check via openssl did show that both files are valid. So it indeed has been a permissions problem! Didn't know that chown'ing the /etc/ssl/*/postfix.pem files to postfix:postfix is not enough for postfix to read the files.

• Linker error when compiling boost.asio example

  Hi, I'm trying to learn a little bit C++ and Boost.Asio. I'm trying to compile the following code example: #include <iostream> #include <boost/array.hpp> #include <boost/asio.hpp> using boost::asio::ip::tcp; int main(int argc, char* argv[]) { try { if (argc != 2) { std::cerr << "Usage: client <host>" << std::endl; return 1; } boost::asio::io_service io_service; tcp::resolver resolver(io_service); tcp::resolver::query query(argv[1], "daytime"); tcp::resolver::iterator endpoint_iterator = resolver.resolve(query); tcp::resolver::iterator end; tcp::socket socket(io_service); boost::system::error_code error = boost::asio::error::host_not_found; while (error && endpoint_iterator != end) { socket.close(); socket.connect(*endpoint_iterator++, error); } if (error) throw boost::system::system_error(error); for (;;) { boost::array<char, 128> buf; boost::system::error_code error; size_t len = socket.read_some(boost::asio::buffer(buf), error); if (error == boost::asio::error::eof) break; // Connection closed cleanly by peer. else if (error) throw boost::system::system_error(error); // Some other error. std::cout.write(buf.data(), len); } } catch (std::exception& e) { std::cerr << e.what() << std::endl; } return 0; } With the following command line: g++ -I /usr/local/boost_1_42_0 a.cpp and it throws an unclear error: /tmp/ccCv9ZJA.o: In function `__static_initialization_and_destruction_0(int, int)': a.cpp:(.text+0x654): undefined reference to `boost::system::get_system_category()' a.cpp:(.text+0x65e): undefined reference to `boost::system::get_generic_category()' a.cpp:(.text+0x668): undefined reference to `boost::system::get_generic_category()' a.cpp:(.text+0x672): undefined reference to `boost::system::get_generic_category()' a.cpp:(.text+0x67c): undefined reference to `boost::system::get_system_category()' /tmp/ccCv9ZJA.o: In function `boost::system::error_code::error_code()': a.cpp:(.text._ZN5boost6system10error_codeC2Ev[_ZN5boost6system10error_codeC5Ev]+0x10): undefined reference to `boost::system::get_system_category()' /tmp/ccCv9ZJA.o: In function `boost::asio::error::get_system_category()': a.cpp:(.text._ZN5boost4asio5error19get_system_categoryEv[boost::asio::error::get_system_category()]+0x7): undefined reference to `boost::system::get_system_category()' /tmp/ccCv9ZJA.o: In function `boost::asio::detail::posix_thread::~posix_thread()': a.cpp:(.text._ZN5boost4asio6detail12posix_threadD2Ev[_ZN5boost4asio6detail12posix_threadD5Ev]+0x1d): undefined reference to `pthread_detach' /tmp/ccCv9ZJA.o: In function `boost::asio::detail::posix_thread::join()': a.cpp:(.text._ZN5boost4asio6detail12posix_thread4joinEv[boost::asio::detail::posix_thread::join()]+0x25): undefined reference to `pthread_join' /tmp/ccCv9ZJA.o: In function `boost::asio::detail::posix_tss_ptr<boost::asio::detail::call_stack<boost::asio::detail::task_io_service<boost::asio::detail::epoll_reactor<false> > >::context>::~posix_tss_ptr()': a.cpp:(.text._ZN5boost4asio6detail13posix_tss_ptrINS1_10call_stackINS1_15task_io_serviceINS1_13epoll_reactorILb0EEEEEE7contextEED2Ev[_ZN5boost4asio6detail13posix_tss_ptrINS1_10call_stackINS1_15task_io_serviceINS1_13epoll_reactorILb0EEEEEE7contextEED5Ev]+0xf): undefined reference to `pthread_key_delete' /tmp/ccCv9ZJA.o: In function `boost::asio::detail::posix_tss_ptr<boost::asio::detail::call_stack<boost::asio::detail::task_io_service<boost::asio::detail::epoll_reactor<false> > >::context>::posix_tss_ptr()': a.cpp:(.text._ZN5boost4asio6detail13posix_tss_ptrINS1_10call_stackINS1_15task_io_serviceINS1_13epoll_reactorILb0EEEEEE7contextEEC2Ev[_ZN5boost4asio6detail13posix_tss_ptrINS1_10call_stackINS1_15task_io_serviceINS1_13epoll_reactorILb0EEEEEE7contextEEC5Ev]+0x22): undefined reference to `pthread_key_create' collect2: ld returned 1 exit status How can I fix it?

• linker error when using tr1::regex

  Hello. I've got a program that uses tr1::regex, and while it compiles, it gives me very verbose linker errors.

• Why would autoconf/automake project link against installed library instead of local development libr

  - by Beau Simensen

  I'm creating a library libgdata that has some tests and non-installed programs. I am running into the problem that once I've installed the library once, the programs seem to be linking to the installed version and not the local version in ../src/libgdata.la any longer. What could cause this? Am I doing something horribly wrong? Here is what my test/Makefile.am looks like: INCLUDES = -I$(top_srcdir)/src/ -I$(top_srcdir)/test/ # libapiutil contains all of our dependencies! AM_CXXFLAGS = $(APIUTIL_CFLAGS) AM_LDFLAGS = $(APIUTIL_LIBS) LDADD = $(top_builddir)/src/libgdata.la noinst_PROGRAMS = gdatacalendar gdatayoutube gdatacalendar_SOURCES = gdatacalendar.cc gdatayoutube_SOURCES = gdatayoutube.cc TESTS = check_bare check_PROGRAMS = $(TESTS) check_bare_SOURCES = check_bare.cc (libapiutil is another library that has some helper stuff for dealing with libcurl and libxml++) So, for instance, if I run the tests without having installed anything, everything works fine. I can make changes locally and they are picked up by these programs right away. If I install the package, these programs will compile (it seems like it does actually look locally for the headers), but once I run the program it complains about missing symbols. As far as I can tell, it is linking against the newly built library (../src/libgdata.la) based on the make output, so I'm not sure why this would be happening. If i remove the installed files, the local changes to src/* are picked up just fine. I've included the make output for gdatacalendar below. g++ -DHAVE_CONFIG_H -I. -I.. -I../src/ -I../test/ -I/home/altern8/workspaces/4355/dev-install/include -I/usr/include/libxml++-2.6 -I/usr/lib/libxml++-2.6/include -I/usr/include/libxml2 -I/usr/include/glibmm-2.4 -I/usr/lib/glibmm-2.4/include -I/usr/include/sigc++-2.0 -I/usr/lib/sigc++-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -g -O2 -MT gdatacalendar.o -MD -MP -MF .deps/gdatacalendar.Tpo -c -o gdatacalendar.o gdatacalendar.cc mv -f .deps/gdatacalendar.Tpo .deps/gdatacalendar.Po /bin/bash ../libtool --tag=CXX --mode=link g++ -I/home/altern8/workspaces/4355/dev-install/include -I/usr/include/libxml++-2.6 -I/usr/lib/libxml++-2.6/include -I/usr/include/libxml2 -I/usr/include/glibmm-2.4 -I/usr/lib/glibmm-2.4/include -I/usr/include/sigc++-2.0 -I/usr/lib/sigc++-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -g -O2 -L/home/altern8/workspaces/4355/dev-install/lib -lapiutil -lcurl -lgssapi_krb5 -lxml++-2.6 -lxml2 -lglibmm-2.4 -lgobject-2.0 -lsigc-2.0 -lglib-2.0 -o gdatacalendar gdatacalendar.o ../src/libgdata.la mkdir .libs g++ -I/home/altern8/workspaces/4355/dev-install/include -I/usr/include/libxml++-2.6 -I/usr/lib/libxml++-2.6/include -I/usr/include/libxml2 -I/usr/include/glibmm-2.4 -I/usr/lib/glibmm-2.4/include -I/usr/include/sigc++-2.0 -I/usr/lib/sigc++-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -g -O2 -o .libs/gdatacalendar gdatacalendar.o -L/home/altern8/workspaces/4355/dev-install/lib /home/altern8/workspaces/4355/dev-install/lib/libapiutil.so /usr/lib/libcurl.so -lgssapi_krb5 /usr/lib/libxml++-2.6.so /usr/lib/libxml2.so /usr/lib/libglibmm-2.4.so /usr/lib/libgobject-2.0.so /usr/lib/libsigc-2.0.so /usr/lib/libglib-2.0.so ../src/.libs/libgdata.so -Wl,--rpath -Wl,/home/altern8/workspaces/4355/dev-install/lib creating gdatacalendar Help. :) UPDATE I get the following messages when I try to run the calendar program when I've added the addCommonRequestHeader() method to the Service class after I had installed the library without the addCommonRequestHeader() method. /home/altern8/workspaces/4355/libgdata/test/.libs/lt-gdatacalendar: symbol lookup error: /home/altern8/workspaces/4355/libgdata/test/.libs/lt-gdatacalendar: undefined symbol: _ZN55gdata7service7Service22addCommonRequestHeaderERKSsS4_ Eugene's suggestion to try setting the $LD_LIBRARY_PATH variable did not help. UPDATE 2 I did two tests. First, I did this after blowing away my dev-install directory (--prefix) and in that case, it creates test/.libs/lt-gdatacalendar. Once I have installed the library, though, it creates test/.libs/gdatacalendar instead. The output of ldd is the same for both with one exception: # before install # ldd test/.libs/lt-gdatacalendar libgdata.so.0 => /home/altern8/workspaces/4355/libgdata/src/.libs/libgdata.so.0 (0xb7c32000) # after install # ldd test/.libs/gdatacalendar libgdata.so.0 => /home/altern8/workspaces/4355/dev-install/lib/libgdata.so.0 (0xb7c87000) What would cause this to create lt-gdatacalendar in one case but gdatacalendar in another?

• Running 32 bit assembly code on a 64 bit Linux & 64 bit Processor : Explain the anomaly.

  - by claws

  Hello, I'm in an interesting problem.I forgot I'm using 64bit machine & OS and wrote a 32 bit assembly code. I don't know how to write 64 bit code. This is the x86 32-bit assembly code for Gnu Assembler (AT&T syntax) on Linux. //hello.S #include <asm/unistd.h> #include <syscall.h> #define STDOUT 1 .data hellostr: .ascii "hello wolrd\n"; helloend: .text .globl _start _start: movl $(SYS_write) , %eax //ssize_t write(int fd, const void *buf, size_t count); movl $(STDOUT) , %ebx movl $hellostr , %ecx movl $(helloend-hellostr) , %edx int $0x80 movl $(SYS_exit), %eax //void _exit(int status); xorl %ebx, %ebx int $0x80 ret Now, This code should run fine on a 32bit processor & 32 bit OS right? As we know 64 bit processors are backward compatible with 32 bit processors. So, that also wouldn't be a problem. The problem arises because of differences in system calls & call mechanism in 64-bit OS & 32-bit OS. I don't know why but they changed the system call numbers between 32-bit linux & 64-bit linux. asm/unistd_32.h defines: #define __NR_write 4 #define __NR_exit 1 asm/unistd_64.h defines: #define __NR_write 1 #define __NR_exit 60 Anyway using Macros instead of direct numbers is paid off. Its ensuring correct system call numbers. when I assemble & link & run the program. $cpp hello.S hello.s //pre-processor $as hello.s -o hello.o //assemble $ld hello.o // linker : converting relocatable to executable Its not printing helloworld. In gdb its showing: Program exited with code 01. I don't know how to debug in gdb. using tutorial I tried to debug it and execute instruction by instruction checking registers at each step. its always showing me "program exited with 01". It would be great if some on could show me how to debug this. (gdb) break _start Note: breakpoint -10 also set at pc 0x4000b0. Breakpoint 8 at 0x4000b0 (gdb) start Function "main" not defined. Make breakpoint pending on future shared library load? (y or [n]) y Temporary breakpoint 9 (main) pending. Starting program: /home/claws/helloworld Program exited with code 01. (gdb) info breakpoints Num Type Disp Enb Address What 8 breakpoint keep y 0x00000000004000b0 <_start> 9 breakpoint del y <PENDING> main I tried running strace. This is its output: execve("./helloworld", ["./helloworld"], [/* 39 vars */]) = 0 write(0, NULL, 12 <unfinished ... exit status 1> Explain the parameters of write(0, NULL, 12) system call in the output of strace? What exactly is happening? I want to know the reason why exactly its exiting with exitstatus=1? Can some one please show me how to debug this program using gdb? Why did they change the system call numbers? Kindly change this program appropriately so that it can run correctly on this machine. EDIT: After reading Paul R's answer. I checked my files claws@claws-desktop:~$ file ./hello.o ./hello.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped claws@claws-desktop:~$ file ./hello ./hello: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped All of my questions still hold true. What exactly is happening in this case? Can someone please answer my questions and provide an x86-64 version of this code?

Headers are created as follows wstring wstrAddHeaders = L"Content-Type: multipart/form-data;boundary=ABCD\r\n"; wstrAddHeaders += L"Host: api.flickr.com\r\n"; wchar_t tempStr[MAX_PATH]; wsprintf(L"Content-Length: %ld\r\n",szTotalSize); wstrAddHeaders += tmpStr; wstrAddHeaders +=L"\r\n"; HINTERNET hSession = InternetConnect(hInternet, L"www.flickr.com", INTERNET_DEFAULT_HTTP_PORT, NULL,NULL, INTERNET_SERVICE_HTTP, 0, 0); if(hSession==NULL) { dwErr = GetLastError(); return; } Content of Post request are created as follows: wstring wstrBoundry = L"--ABCD\r\n"; wstring wstrContent =wstrBoundry; wstrContent +=L"Content-Disposition: form-data; name=\"api_key\"\r\n\r\n"; wstrContent +=wstrAPIKey.c_str() ; wstrContent += L"\r\n"; wstrContent +=wstrBoundry; wstrContent +=L"Content-Disposition: form-data; name=\"auth_token\"\r\n\r\n"; wstrContent +=m_wstrToken.c_str(); wstrContent += L"\r\n"; wstrContent +=wstrBoundry; wstrContent +=L"Content-Disposition: form-data; name=\"api_sig\"\r\n\r\n"; wstrContent +=wstrSig; wstrContent += L"\r\n"; wstrContent +=wstrBoundry; wstrContent +=L"Content-Disposition: form-data; name=\"photo\"; filename=\"C:\\test.jpg\""; wstrContent +=L"\r\n"; wstrContent +=L"Content-Type: image/jpeg\r\n\r\n"; wstring wstrFilePath(L"C:\\test.jpg"); CAtlFile file; HRESULT hr = S_OK; hr = file.Create(wstrFilePath.c_str(),GENERIC_READ,FILE_SHARE_READ,OPEN_EXISTING); if(FAILED(hr)) { return; } ULONGLONG nLen; hr = file.GetSize(nLen); if (nLen > (DWORD)-1) { return ; } char * fileBuf = new char[nLen]; file.Read(fileBuf,nLen); wstring wstrLastLine(L"\r\n--ABCD--\r\n"); size_t szTotalSize = sizeof(wchar_t) * (wstrContent.length()) +sizeof(wchar_t) * (wstrLastLine.length()) + nLen; unsigned char *buffer = (unsigned char *)malloc(szTotalSize); memset(buffer,0,szTotalSize); memcpy(buffer,wstrContent.c_str(),wstrContent.length() * sizeof(wchar_t)); memcpy(buffer+wstrContent.length() * sizeof(wchar_t),fileBuf,nLen); memcpy(buffer+wstrContent.length() * sizeof(wchar_t)+nLen,wstrLastLine.c_str(),wstrLastLine.length() * sizeof(wchar_t)); hRequest = HttpOpenRequest(hSession, L"POST", L"/services/upload/", L"HTTP/1.1", NULL, NULL, 0, NULL); if(hRequest) { bRet = HttpAddRequestHeaders(hRequest,wstrAddHeaders.c_str(),wstrAddHeaders.length(),HTTP_ADDREQ_FLAG_ADD | HTTP_ADDREQ_FLAG_REPLACE); if(bRet) { bRet = HttpSendRequest(hRequest,NULL,0,(void *)buffer,szTotalSize); if(bRet) { while(true) { char buffer[1024]={0}; DWORD read=0; BOOL r = InternetReadFile(hRequest,buffer,1024,&read); if(read !=0) { wstring strUploadXML =buffer; break; } } } } I am not pretty sure the way I am adding image data to the string and posting the request. Do I need to convert image data into Unicode? Any suggestions , if someone can find what I am doing wrong that would be very helpful to me.

• Help in building an 16 bit os

  - by Barshan Das

  I am trying to build an old 16 bit dos like os. My bootloader code: ; This is not my code. May be of Fritzos. I forgot the source. ORG 7c00h jmp Start drive db 0 msg db " Loader Initialization",0 msg2 db "ACos Loaded",0 print: lodsb cmp al, 0 je end mov ah, 0Eh int 10h jmp print end: ret Start: mov [ drive ], dl ; Get the floppy OS booted from ; Update the segment registers xor ax, ax ; XOR ax mov ds, ax ; Mov AX into DS mov si,msg call print ; Load Kernel. ResetFloppy: mov ax, 0x00 ; Select Floppy Reset BIOS Function mov dl, [ drive ] ; Select the floppy ADos booted from int 13h ; Reset the floppy drive jc ResetFloppy ; If there was a error, try again. ReadFloppy: mov bx, 0x9000 ; Load kernel at 9000h. mov ah, 0x02 ; Load disk data to ES:BX mov al, 17 ; Load two floppy head full's worth of data. mov ch, 0 ; First Cylinder mov cl, 2 ; Start at the 2nd Sector to load the Kernel mov dh, 0 ; Use first floppy head mov dl, [ drive ] ; Load from the drive kernel booted from. int 13h ; Read the floppy disk. jc ReadFloppy ; Error, try again. ; Clear text mode screen mov ax, 3 int 10h ;print starting message mov si,msg2 call print mov ax, 0x0 mov ss, ax mov sp, 0xFFFF jmp 9000h ; This part makes sure the bootsector is 512 bytes. times 510-($-$$) db 0 ;bootable sector signature dw 0xAA55 My example kernel code: asm(".code16\n"); void putchar(char); int main() { putchar('A'); return 0; } void putchar(char val) { asm("movb %0, %%al\n" "movb $0x0E, %%ah\n" "int $0x10\n" : :"r"(val) ) ; } This is how I compile it : nasm -f bin -o ./bin/boot.bin ./source/boot.asm gcc -nostdinc -fno-builtin -I./include -c -o ./bin/kernel.o ./source/kernel.c ld -Ttext=0x9000 -o ./bin/kernel.bin ./bin/kernel.o -e 0x0 dd if=/dev/zero of=./bin/empty.bin bs=1440K count=1 cat ./bin/boot.bin ./bin/kernel.bin ./bin/empty.bin|head -c 1440K > ./bin/os rm ./bin/empty.bin and I run it in virtual machine. When I make the putchar function ( in kernel code ) for constant value ....i.e like this: void putchar() { char val = 'A'; asm("movb %0, %%al\n" "movb $0x0E, %%ah\n" "int $0x10\n" : :"r"(val) ) ; } then it works fine. But when I pass argument to it ( That is in the previous code ) , then it prints a space for any character. What should I do?

  I've looked at several related posts but no luck with this error. I receive this undefined reference error message below when my namespace exists across multiple files.
