Can SSH into remote server but can't SCP?

- by ArtfulDodger2012

I can SSH into remote server just fine using private key authentication with prompt for passphrase. However I'm getting permission denied when I try to SCP a file using the same passphrase. Here's my output: $ scp -v [file] [user]@[remoteserver.com]:/home/[my dir] Executing: program /usr/bin/ssh host [remoteserver.com], user [user], command scp -v -t /home/[my dir] OpenSSH_5.3p1 Debian-3ubuntu7, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /home/[my dir].ssh/config debug1: Applying options for [remoteserver.com] debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to [remoteserver.com] [[remoteserver.com]] port 22. debug1: Connection established. debug1: identity file /home/[user]/.ssh/aws_corp type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.3p1 Debian-3ubuntu7 debug1: match: OpenSSH_5.3p1 Debian-3ubuntu7 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.3p1 Debian-3ubuntu7 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host '[remoteserver.com]' is known and matches the RSA host key. debug1: Found key in /home/[my dir]/.ssh/known_hosts:12 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/[my dir]/.ssh/aws_corp debug1: PEM_read_PrivateKey failed debug1: read PEM private key done: type <unknown> Enter passphrase for key '/home/[my dir]/.ssh/aws_corp': debug1: read PEM private key done: type RSA Connection closed by [remote server] lost connection I've searched for answers but can't find quite the same problem or am just being thick.

What's the mysql-5.5 compilation configuration arguments on Ubuntu 10.04?

- by photon

I want to install mysql 5.5 on my Ubuntu10.04 desktop system. But I'm not sure what arguments I should use after the cmake command. Though I've seen these articles: https://wikis.oracle.com/display/mysql/Cmake Building mysql-5.5.19 from source on ubuntu 11.10 with the static flag Compile MySQL 5.5.15 from source using autorun.sh and cmake, unable to start MySQL after Would anyone like to share the mysql-5.5 configuration arguments of compilation on Ubuntu 10.04? $cmake # what arguments to enter for this command update: cmake . -DBUILD_CONFIG=mysql_release -DCMAKE_INSTALL_PREFIX=/path/to/mysql_installation_dir -DWITH_SSL=no the official web site says it need to use cmake to compile the source package, but according to a teck blog, it doesn't need to compile the source, so which one is correct? When I use Cmake, I also had following error message: $ sudo cmake . -DBUILD_CONFIG=mysql_release -DCMAKE_INSTALL_PREFIX=/usr/local/mysql_community_5.5 -- The CXX compiler identification is unknown CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.

And I cannot find a clever guy around me to give me some useful help. So I come here and hope someone is kind and generous enough to take the time to post the details.

Moving a lot of small files between servers using rsync

- by Adirael

Hello guys, I'm moving a lot of files (about 2 millions) between two servers on different locations using rsync over ssh, it seems to work fine but I just realised I'm losing some files on the process. I got server 1, with the original data, and server 2, with the copy. Server 1 runs CentOS 5 and Server 2 runs on Ubuntu 10. I'm doing the transfer on the Server's 2 command line like this: rsync -e ssh -avzn usr@server1:/remote/path /local/path The first file movement I did using tar, but I didn't though of piping it through ssh and it failed cause the disk on server 1 was almost full, so I transfered it anyways (it was about 200GB) and got about 80% of the files. Then I piped another tar with the rest of the files (they're in folders, I got 100 folders with about 30 subfolders each, with files inside) and now I got everything on server 2. I wanted to be sure, so I my two options are getting the md5sum of all the files and check them or running an rsync on server 2 against server 1, that's what I did. It got some missing stuff and now it says there's nothing more to do (DRY RUN). But I got at least two files that are missing inside a subfolder. I ran that same rsync on that folder, but still dry run. Am I doing something wrong? Thanks, and sorry for the wall of text.

Problem with ubuntu 10.10 running from USB drive

- by Surjya Narayana Padhi

I recently downloaded Ubuntu 10.10 and created an USB drive with that. I started to run the Ubuntu from that USB drive. But I am facing so much problem. I am thinking why its not so much easy like Windows to do all my job in ubuntu. Always I get some error message or to install something. This time I am getting the following errors. I am trying to download and install Aircrack-ng. So used the command sudo apt-get install aircrack-ng. But the installation stops with the following error : update-initramfs: deferring update (trigger activated) cp: cannot stat `/vmlinuz': No such file or directory dpkg: error processing bcmwl-kernel-source (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: initramfs-tools bcmwl-kernel-source E: Sub-process /usr/bin/dpkg returned an error code (1) I don't even have the aptitude command installed till now. Are all these errors because of I am running the ubuntu from USB drive? Is there any simple and easy way to go to Ubuntu Software Center and download all the required essentials at one shot and then Aircrack-ng? I could not find the Aircrack-ng in Ubuntu Software Center Can anybody give me detail steps to solve all my problems above. I am frustrated searching for updates and installations. When something works and something does not work. Can anybody suggest me how I should proceed after installing ubuntu to run on a USB drive. So that I can use the OS like Windows. Like software download,wireless driver, sound, video, documents, C:, D: all things should be there. Please somebody help.

Chef bash resource not executing as specified user

- by Arthur Maltson

I'm writing a Chef cookbook to install Hubot. In the recipe, I do the following: bash "install hubot" do user hubot_user group hubot_group cwd install_dir code <<-EOH wget https://github.com/downloads/github/hubot/hubot-#{node['hubot']['version']}.tar.gz && \ tar xzvf hubot-#{node['hubot']['version']}.tar.gz && \ cd hubot && \ npm install EOH end However, when I try to run chef-client on the server installing the cookbook, I'm getting a permission denied writing to the directory of the user that runs chef-client, not the hubot user. For some reason, npm is trying to run under the wrong user, not the user specified in the bash resource. I am able to run sudo su - hubot -c "npm install /usr/local/hubot/hubot" manually, and this gets the result I want (installs hubot as the hubot user). However, it seems chef-client isn't executing the command as the hubot user. Below you'll find the chef-client execution. Thank you in advance.

Unable to ssh in Beagle Bone Black

- by SamuraiT

I wanted to install pip onto beagle bone black,and I tried this: /usr/bin/ntpdate -b -s -u pool.ntp.org opkg update && opkg install python-pip python-setuptools then, it threw errors,but Unfortunately, I didn't log that errors. it was occurred a week ago and was't solved yet. I wanted to solve it now and I tried connect by ssh,but I failed. When I ping to beagle bone, it responds, and Cloud9 IDE is working too but not ssh. I don't think this is serious problem since I can connect to beagle bone by other methods: Cloud9 or so. However, to use python on beagle bone, I need to connect by ssh. Before trying to update and install python-pip, I could connect by ssh. Do you have any ideas to solve this connection problem? note I use default OS: Angstrom I don't use SD card. HOST PC is mac, OS.X 10.9 connect by USB serial I checked this but this wasn't helpful http://stackoverflow.com/questions/19233516/cannot-connect-to-beagle-bone-black I could connect by GateOne SSH client, but still unable to connect from terminal.

javascript doesn't seem to be able to post form data (nginx server w/ php-fpm)

- by Jones

So the situation is like so: I have a nginx server with php-fpm installed. All is well and the site scripts and all work perfectly. I am able to use html to POST form data and it works just fine. However, There seems to be be some correlation between javascript, the POST protocol and nothing happening. I cant seem to determine the issue. Example: I have a user login widget that uses javascript on submit the fields and POST the data to a backend auth script which returns a server message that then populates the login box saying something like "Login Successful" followed by reloading the page to properly enable content. Problem is, nothing happens when you hit submit. I do know the setup works because i had it working on apache before migrating. Also if it makes any difference, the server is a Amazon EC2 instance using the Amazon AMI. I really dont know where to start looking on this one, but below is my default.conf for the server: upstream backend_get { server 127.0.0.1:80 weight=1; } upstream backend_post { server 127.0.0.1:80 weight=1; } #Main website url server { listen 80; server_name server.com; #charset koi8-r; access_log logs/host.access.log main; error_log logs/host.error.log; location / { root /usr/share/nginx/html; index index.php index.html index.htm; if ($request_method = POST) { proxy_pass http://backend_post; break; } } location ~ \.php$ { #fastcgi_pass 127.0.0.1:9000; fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }

Ngins wont send POST to fastcgi backend, but GET works fine?

- by xyld

Not sure why, but it is happy sending a GET to the fastcgi backend (Mercurial hgwebdir in this case), but simply resorts to the filesystem if the request is a POST. Relevant parts of nginx.conf: location / { root /var/www/htdocs/; index index.html; autoindex on; } location /hg { fastcgi_pass unix:/var/run/hg-fastcgi.socket; include fastcgi_params; if ($request_uri ~ ^/hg([^?#]*)) { set $rewritten_uri $1; } limit_except GET { allow all; deny all; auth_basic "hg secured repos"; auth_basic_user_file /var/trac.htpasswd; } fastcgi_param SCRIPT_NAME "/hg"; fastcgi_param PATH_INFO $rewritten_uri; # for authentication fastcgi_param AUTH_USER $remote_user; fastcgi_param REMOTE_USER $remote_user; #fastcgi_pass_header Authorization; #fastcgi_intercept_errors on; } GET's work fine, but POST delivers this error to the error_log: 2010/05/17 14:12:27 [error] 18736#0: *1601 open() "/usr/html/hg/test" failed (2: No such file or directory), client: XX.XX.XX.XX, server: domain.com, request: "POST /hg/test HTTP/1.1", host: "domain.com" What could possibly be the issue? I'm trying to allow read-only access via GET's to the page, but require authorization when using hg push to the same url which sends a POST request.

How do I get a network printer installed in ubuntu 9.04?

- by SoaperGEM

My girlfriend's work computer now has Linux on one of the partitions, and for the most part it's running fine--except that I can't seem to get the network printers configured right. There are two of them: a Lanier MP 7500/LD275 and a Lanier MP C3000/LD430c, and Linux seems to have found them both automatically. I'll go through the steps of what I did, and what exactly went wrong. I went to Administration Printing, and clicked the new printer button. It searched for printers and found them both, listed under "Network Printers." I added them as new printers in succession. However, when I clicked "Print a Test Page," it failed saying there was a broken pipe. The device URIs were saved as socket://[ip address]:9100. I changed these to lpd://[ip address] per some online tutorial, which at first looked like it might have worked (but didn't). Then when I tried to print a test page, it first said Processing (and sometimes even Processing - printing test page, 4%, but always subsequently displays Idle - /usr/lib/cups/backend/lpd failed. Help! What do I do? It seems like Linux can find these printers just fine, and the drivers seem to be in place, so what's going wrong?

Mysqld shutting down by itself

I'm running a Wordpress Blog that gets medium-high traffic. It is hosted in an Ubuntu Server 2GB Memory 2 Core Processor 40GB SSD Disk, 3TB Transfer. The problem is that MySQL shuts down by itself after an hour or two. I had to restart mysql each and every time this happens. I checked the logs and this is what I found: 140612 6:48:14 [Warning] Using unique option prefix myisam-recover instead of myisam-recover-options is deprecated and will be removed in a future release.

Error authenticating git repository with Redmine

Low-traffic WordPress website on Apache keeps crashing server

- by OC2PS

I have recently moved my low-moderate traffic (1000 UAUs, 5000 pageviews on a busy day) website from shared hosting to a Centos 6 64-bit VPS with Apache and cPanel running on 4 quad-core processor (likely oversold) and 3GB memory (Xen). We've had problems from the beginning. The server keeps crashing. It seems PHP keeps expanding till it consumes all the memory and crashes the server. Some folks have suggested that I should abandon Apache/cPanel/PHP/mySQL and go with nginX/Varnish/PHP-FPM/SQLite. But that's just not possible for me as I am not very tech savvy and need a simple GUI like cPanel to be able to manage the mundane management tasks (can't afford to hire system administrator or get fully managed hosting). I have come across several posts discussing optimization of Apache for WordPress. But all of these lead to articles that are pretty dated such as this ~4 year old one from Jan 2009 - http://thethemefoundry.com/blog/optimize-apache-wordpress/ The article is pretty detailed and seems helpful, but I stumble even on the first step. My httpd.conf only has 2 loadmodule commands LoadModule fastinclude_module modules/mod_fastinclude.so LoadModule bwlimited_module modules/mod_bwlimited.so So I go total bust right there. Further, my httpd.conf says Direct modifications to the Apache configuration file may be lost upon subsequent regeneration of the configuration file. To have modifications retained, all modifications must be checked into the configuration system by running: /usr/local/cpanel/bin/apache_conf_distiller I am having trouble finding where to change the modules in WHM. Please can someone help me with updated guidelines on how to optimize Apache for WordPress? Many thanks! P.S. The WordPress installation also has WP Super Cache installed. P.P.S. I also have phpBB, OpenCart, and Menalto Gallery installed.

PHP pages are not parsed by Apache on CentOS

- by Ram

I have installed Centos 5.x, Apache 2.2, PHP 5.3 and MySQL 5.5. I also installed phpMyAdmin. I am able to access phpMyAdmin through the browser without any issues. However, when I create a simple index.php with phpinfo() function in the default directory, that page is served without php parsing. As we all know, phpMyAdmin is a php application. This is working fine from the same server but not the simple php page from the doc root directory ??!!!. Of course, I tried moving this page into phpMyAdmin folder and tried accessing it, but no success. Please note that I updated httpd.conf file with appropriate directives based on the php installation guide.Following directives were added to httpd.conf. AddTyoe application/x-httpd-php LoadModule php5_module /usr/lib/httpd/modules/libphp5.so <FilesMatch "\.php$"> SetHandler application/x-httpd-php </FilesMatch> File locations are: docroot - /var/www/html phpMyAdmin folder - /var/www/html/phpMyAdmin File privileges are: [root@linuxdev1 html]# ls -Z -rwxr-xr-x root root index.php drwxr-xr-x root root phpMyAdmin -rw-r--r-- root root phpMyAdmin-3.4.3.2-english.tar.gz drwxr-xr-x root root test1 Any help is appreciated.

openvpn in a bridge?

- by sebelk

I have a somewhat tricky proble to solve. We have a wireless link between 2 building. One of them has an mikrotik and below there are some vlans. Some machines of one vlan need to use openvpn to connect to a remote private lan. I put a TP-Link WR1043ND (which those machines connect to) with openwrt with ebtables just in case I need it. I've configured openwrt in such a way that all ports belongs to the same vlan. My idea was to make things as transparent as I can. It has a bridge as follows: usr/sbin/brctl-full show br-lan bridge name bridge id STP enabled interfaces br-lan 8000.f8d111565716 no eth0.1 eth0.2 Also I've added an ebtables rule: ebtables -t broute -A BROUTING -p ipv4 -j DROP So "bridge" has only one IP address. I've installed openvpn and I'm trying to bring up the tunnel but I can't still get working. Sure, someone can says why don't you use the vpn on the mikrotik, there are some reasons, the first one is I have little experience with mikrotik and I'd want to have the vpn at hand :) The problem is that openvpn is not working, because it is complaining that I have only one Ip Address on the server side. So I set up and alias interface with another IP address but is not working either: : Rejected connection attempt from IP-Client-Side:37801 due to --remote setting Is there a way to make it work?

disk space keeps filling up on EC2 instance with no apperent files/directories

- by sasher

How come os shows 6.5G used but I see only 3.6G in files/directories? Running as root on an Amazon Linux AMI (seems like Centos), lots of free memory available, no swapping going on, no apparent file descriptors issue. The only thing I can think of is a log file that was deleted while applications append to it. Disk space usage is slowly but continuously rising towards full capacity (~1k/min with very small decreases from time to time) Any explanation? Solution? du --max-depth=1 -h / 1.2G /usr 4.0K /cgroup 22M /lib64 11M /sbin 19M /etc 52K /dev 2.1G /var 4.0K /media 0 /sys 4.0K /selinux du: cannot access /proc/14024/task/14024/fd/4': No such file or directory du: cannot access<br/> /proc/14024/task/14024/fdinfo/4': No such file or directory du: cannot access /proc/14024/fd/4': No such file or directory du: cannot<br/> access/proc/14024/fdinfo/4': No such file or directory 0 /proc 18M /home 4.0K /logs 8.1M /bin 16K /lost+found 12M /tmp 4.0K /srv 35M /boot 79M /lib 56K /root 67M /opt 4.0K /local 4.0K /mnt 3.6G / df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda1 7.9G 6.5G 1.4G 84% / tmpfs 3.7G 0 3.7G 0% /dev/shm sysctl fs.file-nr fs.file-nr = 864 0 761182

Convention location for JAR files for a LaunchDaemon on OS X?

- by Barry Wark

I'm setting up a Hudson build slave on an OS X machine. I'm using launchd to start the slave using the following plist in `/Library/LaunchDaemons/': <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>KeepAlive</key> <true/> <key>Label</key> <string>org.hudson-ci.jnlpslave</string> <key>ProgramArguments</key> <array> <string>/usr/bin/java</string> <string>-jar</string> <string>/Users/Shared/Hudson/slave.jar</string> <string>-noCertificateCheck</string> <string>-jnlpUrl</string> <string>file:///Users/Shared/Hudson/slave-agent.jnlp</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist> I'm currently putting the slave.jar and slave-agent.jnlp files in /Users/Shared/Hudson but this seems like an unnecessarily user-visible location. What's the convention? Where should I be putting these JARs for a daemon?

CPANEL ModSec2 not working with SecFilterSelective

- by jfreak53

Ok, I have cPanel/WHM latest on a Dedi, here are my specs on apache: Server version: Apache/2.2.23 (Unix) Server built: Oct 13 2012 19:33:23 Cpanel::Easy::Apache v3.14.13 rev9999 I just ran a re-compile using easyapache as you can see by the date. When running it I made sure that ModSec was selected and it stated in big bold letters something to the effect of If you install Apache 2.2.x you get ModSec 2 So I believed it :) I recompiled, I then ran: grep -i release /home/cpeasyapache/src/modsecurity-apache_2.6.8/apache2/mod_security2.c Hmm, the file is there but grep doesn't output anything, if I run: grep -i release /home/cpeasyapache/src/modsecurity-apache_1.9.5/apache2/mod_security.c I of course get the ModSec 1 version output. But the thing is that ModSec2 is installed since the c file is there. So I continued and put the following in modsec2.user.conf: SecFilterScanOutput On SecFilterSelective OUTPUT "text" Now when I restart Apache I get this error: Syntax error on line 1087 of /usr/local/apache/conf/modsec2.user.conf: Invalid command 'SecFilterScanOutput', perhaps misspelled or defined by a module not included in the server configuration Now supposedly this is supposed to work, I even have it running in ModSec2 on a non-cpanel server setup manually. So I know ModSec2 supports it. Anyone have any ideas? I have asked this question over at cpanel forum and it got nowhere.

Debugging nginx URL rewrite: How do I figure out where the problem is?

- by pjmorse

I have a specific URL pattern on a site which needs to be redirected to the HTTPS version. This is a Django site; Nginx checks each URL in memcached, and if it doesn't find a cached version it proxies the request to Apache/mod_python for Django to render the page. The relevant configuration block is rewrite ^/certificate https://mysite.com/certificate ; rewrite ^/([a-zA-Z]{2})/certificate https://mysite.com/certificate ; ...and it doesn't appear to be working at all. Nginx is: $ nginx -V nginx version: nginx/0.7.65 built by gcc 4.2.4 (Ubuntu 4.2.4-1ubuntu4) TLS SNI support disabled configure arguments: --prefix=/usr/local/nginx --pid-path=/var/run/nginx.pid --with-http_gzip_static_module --with-http_ssl_module How can I figure out if the problem is my patterns not matching, or a more obscure configuration problem? (The site is localized to three languages, and the localization is in the URL string, e.g. /US/news/, /DE/about, etc. It tracks localization in the session as well, defaulting to US, so if you just requested /news Django will rewrite to /US/news unless the user has a cookie indicating they're using a different localization. Django handles this, though, not Nginx.)

Tuning up a MySQL server

- by NinjaCat

I inherited a mysql server, and so I've started with running the MySQLTuner.pl script. I am not a MySQL expert but I can see that there is definitely a mess here. I'm not looking to go after every single thing that needs fixing and tuning, but I do want to grab the major, low hanging fruit. Total Memory on the system is: 512MB. Yes, I know it's low, but it's what we have for the time being. Here's what the script had to say: General recommendations: Run OPTIMIZE TABLE to defragment tables for better performance MySQL started within last 24 hours - recommendations may be inaccurate Enable the slow query log to troubleshoot bad queries When making adjustments, make tmp_table_size/max_heap_table_size equal Reduce your SELECT DISTINCT queries without LIMIT clauses Increase table_cache gradually to avoid file descriptor limits Your applications are not closing MySQL connections properly Variables to adjust: query_cache_limit (> 1M, or use smaller result sets) tmp_table_size (> 16M) max_heap_table_size (> 16M) table_cache (> 64) innodb_buffer_pool_size (>= 326M) For the variables that it recommends that I adjust, I don't even see most of them in the mysql.cnf file. [client] port = 3306 socket = /var/run/mysqld/mysqld.sock [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 [mysqld] innodb_buffer_pool_size = 220M innodb_flush_log_at_trx_commit = 2 innodb_file_per_table = 1 innodb_thread_concurrency = 32 skip-locking big-tables max_connections = 50 innodb_lock_wait_timeout = 600 slave_transaction_retries = 10 innodb_table_locks = 0 innodb_additional_mem_pool_size = 20M user = mysql socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp skip-external-locking bind-address = localhost key_buffer = 16M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 4 myisam-recover = BACKUP query_cache_limit = 1M query_cache_size = 16M log_error = /var/log/mysql/error.log expire_logs_days = 10 max_binlog_size = 100M skip-locking innodb_file_per_table = 1 big-tables [mysqldump] quick quote-names max_allowed_packet = 16M [mysql] [isamchk] key_buffer = 16M !includedir /etc/mysql/conf.d/
