  • Apache2 config variable is not defined

    - by Kurt Bourbaki
    I installed apache2 on ubuntu 13.10. If I try to restart it using sudo /etc/init.d/apache2 restart I get this message: AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message So I read that I should edit my httpd.conf file. But, since I can't find it in /etc/apache2/ folder, I tried to locate it using this command: /usr/sbin/apache2 -V But the output I get is this: [Fri Nov 29 17:35:43.942472 2013] [core:warn] [pid 14655] AH00111: Config variable ${APACHE_LOCK_DIR} is not defined [Fri Nov 29 17:35:43.942560 2013] [core:warn] [pid 14655] AH00111: Config variable ${APACHE_PID_FILE} is not defined [Fri Nov 29 17:35:43.942602 2013] [core:warn] [pid 14655] AH00111: Config variable ${APACHE_RUN_USER} is not defined [Fri Nov 29 17:35:43.942613 2013] [core:warn] [pid 14655] AH00111: Config variable ${APACHE_RUN_GROUP} is not defined [Fri Nov 29 17:35:43.942627 2013] [core:warn] [pid 14655] AH00111: Config variable ${APACHE_LOG_DIR} is not defined [Fri Nov 29 17:35:43.947913 2013] [core:warn] [pid 14655] AH00111: Config variable ${APACHE_LOG_DIR} is not defined [Fri Nov 29 17:35:43.948051 2013] [core:warn] [pid 14655] AH00111: Config variable ${APACHE_LOG_DIR} is not defined [Fri Nov 29 17:35:43.948075 2013] [core:warn] [pid 14655] AH00111: Config variable ${APACHE_LOG_DIR} is not defined AH00526: Syntax error on line 74 of /etc/apache2/apache2.conf: Invalid Mutex directory in argument file:${APACHE_LOCK_DIR} Line 74 of /etc/apache2/apache2.conf is this: Mutex file:${APACHE_LOCK_DIR} default I gave a look at my /etc/apache2/envvar file, but I don't know what to do with it.

  • OSX: Mimic Ubuntu IP Masquerading via iptables with ipfw

    - by Dogbert
    Good day, I am attempting to replicate a setup I have between a router and an Ubuntu PC, and have the same setup working on my MacBook (10.6, Snow Leopard). First, I have a router that has a USB port. When I plug it into my Ubuntu PC, it creates an RNDIS connection, allowing me to connect to the router over the USB cable via an IP connection. When I plug it into my computer via USB, it gets assigned an IP address of 172.16.84.1, and a new adapter appears when I type ifconfig. I can then SSH into the device via ssh [email protected]. When I log in to the device, I flush the routes, then create the default route: admin@localhost> route -f admin@localhost> route add default 172.16.84.2 Now, in my Ubuntu machine, I use iptables to enable IP masquerading: root@Valhalla> sudo iptables -t nat -A POSTROUTING -s 172.16.84.2 -j MASQUERADE Once this is all done, the router has internet access over the USB connection to my PC. I am trying to replicate this exact setup on my MacBook now (Snow Leopard), but iptables does not exist for OSX, not even a Macports version exists. I have scoured through other questions on StackOverflow that cover the usage of the ipfw command, which apparently works as a drop-in replacement for iptables. However, the syntax is significantly different, and I'm pretty much lost. Does anyone with some experience with ipfw have some suggestions on how I could accomplish this and create a NAT connection via IP masquerading like I could with my Ubuntu PC? Thank you for your assistance.

  • Using smartctl to get vendor specific Attributes from ssd drive behind a SmartArray P410 controller

    - by Lairsdragon
    Recently I have deployed some HP server with SSD's behind a SmartArray P410 controller. While not official supported from HP the server work well sofar. Now I like to get wear level info's, error statistics etc from the drive. While the SA P410 supports a passthru of the SMART Command to a single drive in the array the output I was not able to the the interesting things from the drive. In this case especially the value the Wear level indicator is from interest for me (Attr.ID 233), but this is ony present if the drive is directly attanched to a SATA Controller. smartctl on directly connected ssd: # smartctl -A /dev/sda smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 5 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 3 Spin_Up_Time 0x0000 100 000 000 Old_age Offline In_the_past 0 4 Start_Stop_Count 0x0000 100 000 000 Old_age Offline In_the_past 0 5 Reallocated_Sector_Ct 0x0002 100 100 000 Old_age Always - 0 9 Power_On_Hours 0x0002 100 100 000 Old_age Always - 8561 12 Power_Cycle_Count 0x0002 100 100 000 Old_age Always - 55 192 Power-Off_Retract_Count 0x0002 100 100 000 Old_age Always - 29 232 Unknown_Attribute 0x0003 100 100 010 Pre-fail Always - 0 233 Unknown_Attribute 0x0002 088 088 000 Old_age Always - 0 225 Load_Cycle_Count 0x0000 198 198 000 Old_age Offline - 508509 226 Load-in_Time 0x0002 255 000 000 Old_age Always In_the_past 0 227 Torq-amp_Count 0x0002 000 000 000 Old_age Always FAILING_NOW 0 228 Power-off_Retract_Count 0x0002 000 000 000 Old_age Always FAILING_NOW 0 smartctl on P410 connected ssd: # ./smartctl -A -d cciss,0 /dev/cciss/c1d0 smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net (Right, it is complety empty) smartctl on P410 connected hdd: # ./smartctl -A -d cciss,0 /dev/cciss/c0d0 smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Current Drive Temperature: 27 C Drive Trip Temperature: 68 C Vendor (Seagate) cache information Blocks sent to initiator = 1871654030 Blocks received from initiator = 1360012929 Blocks read from cache and sent to initiator = 2178203797 Number of read and write commands whose size <= segment size = 46052239 Number of read and write commands whose size > segment size = 0 Vendor (Seagate/Hitachi) factory information number of hours powered up = 3363.25 number of minutes until next internal SMART test = 12 Do I hunt here a bug, or is this a limitation of the p410 SMART cmd Passthru?

  • Chmod 644 on /etc/ any way to fix?

    - by DazSlayer
    I tried to tab complete something and I guess it wasnt there. I know you are not supposed to set the permissions to /etc/ like that, but my permissions seem to be all messed up. whoami prints out cannot find name for user ID 1002 and I cannot cd into /etc/ anymore. passwd and shadow use 640 and 644 so I am not sure why this is a problem. Regardless, is there any way to fix this? The command run was sudo chmod 644 /etc/ I have no name!@vpn-server:/$ whoami whoami: cannot find name for user ID 1002 I have no name!@vpn-server:/$ cd etc bash: cd: etc: Permission denied I have no name!@vpn-server:/$ ls -al etc d????????? ? ? ? ? ? . d????????? ? ? ? ? ? .. d????????? ? ? ? ? ? acpi -????????? ? ? ? ? ? adduser.conf I have no name!@vpn-server:/$ sudo su sudo: can't open /etc/sudoers: Permission denied

  • Connecting to RDS database from EC2 instance using bind9 CNAME alias

    - by mptre
    I'm trying to get internal DNS up and running on a EC2 instance. The main goal is to be able to define CNAME aliases for other AWS services. For example: Instead of using the RDS endpoint, which might change over time, an alias mysql.company.int can be used instead. I'm using bind9 and here's my config files: /etc/bind/named.conf.local zone "company.int" { type master; file "/etc/bind/db.company.int"; }; /etc/bind/db.company.int ; $TTL 3600 @ IN SOA company.int. company.localhost. ( 20120617 ; Serial 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Negative Cache TTL ; @ IN NS company.int. @ IN A 127.0.0.1 @ IN AAAA ::1 ; CNAME mysql IN CNAME xxxx.eu-west-1.rds.amazonaws.com. The dig command ensures me my alias is working as excepted: $ dig mysql.company.int ... ;; ANSWER SECTION: mysql.company.int. 3600 IN CNAME xxxx.eu-west-1.rds.amazonaws.com. xxxx.eu-west-1.rds.amazonaws.com. 60 IN CNAME ec2-yyy-yy-yy-yyy.eu-west-1.compute.amazonaws.com. ec2-yyy-yy-yy-yyy.eu-west-1.compute.amazonaws.com. 589575 IN A zzz.zz.zz.zzz ... As far as I can understand a reverse zone isn't needed for a simple CNAME alias. However when I try to connect to MySQL using my newly created alias the operation is giving me a timeout. $ mysql -uuser -ppassword -hmysql.company.int ERROR 2003 (HY000): Can't connect to MySQL server on 'mysql.company.int' (110) Any ideas? Thanks in advantage!

  • Quick, Linux-compatible unit-aware calculator

    - by endolith
    I want to be able to press a keyboard combination, start typing a mathematical expression that includes units and slightly advanced math (not just a four-function calculator), and get a result immediately, in units that I specify, that I can copy and paste. Currently I open Firefox and press Ctrl+K, type in the search box, and it usually gives me a result in the drop-down from Google Calculator. It doesn't always, though, so I press "=" at the end, wait for a result, remove the equals, wait for a result, realize it doesn't understand the way I typed a unit, open the result in a new tab, etc. it sucks. Wolfram Alpha is smarter, but very much slower, and the output is all images, not text, and I don't have a quick widget for it, if such a thing could even exist. GNU units has a ton of units, which is great, and I can define my own units, which is great, but they have to be written in specific, unintuitive ways, it doesn't handle much advanced math, and I'd need to open a terminal, start units, etc. I hate the command line. I wasted a lot of time trying to make front-ends for units in Deskbar and Launchy, but I'm not a real coder and I don't use either of those anymore. Any other solutions or enhancements of these?

  • Sendmail in Nexenta core 3.0.1

    - by maximdim
    I'm trying to setup sendmail in Nexenta core 3.0.1 (Solaris based OS). All I want is to be able to send emails from that host - like notifications about failures, cron jobs output etc. Initially Nexenta core doesn't have sendmail so here is what I've done: apt-get install sunwsndmu Now there is a sendmail in /usr/sbin/sendmail. When I try to send email from command line: $mail maxim test . It doesn't give me any error but in log file I see: Dec 20 12:41:08 nas sendmail[12295]: [ID 801593 mail.info] oBKHf8u7012295: from=maxim, size=107, class=0, nrcpts=1, msgid=<201012201741.oBKHf8u7012295@nas>, relay=maxim@localhost Dec 20 12:41:08 nas sendmail[12295]: [ID 801593 mail.info] oBKHf8u7012295: to=maxim, ctladdr=maxim (1000/10), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30107, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1] So I guess I need to have SMTP service running. How do I do that in Nexenta? svcs -a | grep sendmail doesn't return anything and # svcadm enable sendmail svcadm: Pattern 'sendmail' doesn't match any instances I'm not married to sendmail so if there are easier ways to achieve y goal I'm open to suggestions as well. Thanks,

  • Nginx ignores HTTP Authentication for WordPress login directory

    - by MrNerdy
    I am running WordPress in a subfolder of my domain for testing and development purposes on a VPS LEMP-stack. In order to password-protect the wp-login.php with an etxra layer, I used HTTP authentication for the wp-admin folder. The problem is that the http authentication is ignored. When the wp-login.php or wp-admin-folder is called, it goes directly to the normal WordPress-login. I installed everything from the command line in the following way: sudo apt-get install apache2-utils sudo htpasswd -c /var/www/bitmall/wp-admin/.htpasswd exampleuser New password: Re-type new password: Adding password for user exampleuser My Nginx configuration file looks like this: server { listen 80; root /var/www; index index.php index.html index.htm; server_name example.com; location / { try_files $uri $uri/ /index.html; } location /bitmall/wp-admin/ { auth_basic "Restricted Section"; auth_basic_user_file /var/www/bitmall/wp-admin/.htpasswd; } location ~ /\.ht { deny all; } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root /var/www; } # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 location ~ \.php$ { try_files $uri =404; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } I would appreciate your advive on this.

  • How to make 7-Zip faster

    - by Matt
    I normally use WinRAR over 7-Zip simply because it's faster and only a little less efficient with compression. I did a few tests on different filetypes and sizes comparing the 7-Zip and WinRAR default settings on their normal compression and their best compression, and in a lot of cases WinRAR was 50% faster and in some it was actually 100% faster. But, I do like FOSS more. So here are my questions: Is there a way to make 7-Zip speed up? I'd like it to at least be on par with WinRAR's speed Is there a way to make recovery segments in 7-Zip like you can in WinRAR? I didn't see any, but I guess it could be a command line thing. I tested WinRAR and 7-Zip using the latest stable version of each (4-dot-something with 7-Zip). Is the 9.x beta release noticeably faster at compression? I'm talking about faster at a comparable setting in WinRAR, not just lowering to bare minimum compression. If it matters, I use a quad core Intel i7 720 (1.6 GHz)/(2.8 GHz) with 4 GB DDR3 RAM, and the 64-bit version of 7-Zip, and dual-boot Debian x64 5.0.4 and Windows 7 Home.

  • Safe mode boot with no change on screen but ongoing hard disk activity - why?

    - by omatai
    I have a machine with a dying hard drive - bad sectors are starting to multiply :-( The first sign (24 hours ago) was that it had an unmountable boot volume. At this time, I tried booting to safe mode with command prompt, which worked, after which I rebooted normally and ran a chkdsk. It has since been working as well as I could expect, but slowly getting less reliable. So I scheduled another chkdsk on both partitions (C: - boot, D: - data), having freed up a lot of space on both partitions to give Windows a little more scope for repairs (hopefully?). I then rebooted. On reboot, it protested about the unmountable boot volume again, so I booted to safe mode. I got the same list of drivers loaded as yesterday, and then no change to the screen for the past 2 hours. However, I see a flickering hard drive indicator light - not always on, but seldom ever off. What is happening? Is the chkdsk that runs in safe mode one which produces nothing on the screen and so chkdsk could be doing its thing... or is Windows still trying (but failing) to boot into Safe Mode?

  • supervisord launches with wrong setuid

    - by friendzis
    I am trying to test a pilot system with nginx connecting to uwsgi served application controlled by supervisord running on ubuntu-server. Application is written in python with Flask in virtualenv, although I'm not sure if that is relevant. To test the system I have created a simple hello world with flask. I want nginx and uwsgi both to run as www-data user. If I launch uwsgi "manually" from root shell I can see uwsgi processes runing as appropriate user (www-data). Although, if I let supervisor launch the application something strange happens - uwsgi processes are runing under my user (friendzis). Consequently, socket file gets created under wrong user and nginx cannot communicate with my applicaion. note: the linux server runs as Hyper-V VM, under Windows Server 2008. Relevant configuration: [uwsgi] socket = /var/www/sockets/cowsay.sock chmod-socket = 666 abstract-socket = false master = true workers = 2 uid = www-data gid = www-data chdir = /var/www/cowsay/cowsay pp = /var/www/cowsay/cowsay pyhome = /var/www/cowsay module = cowsay callable = app supervisor [program:cowsay] command = /var/www/cowsay/bin/uwsgi -s /var/www/sockets/cowsay.sock -w cowsay:app directory = /var/www/cowsay/cowsay user = www-data autostart = true autorestart = true stdout_logfile = /var/www/cowsay/log/supervisor.log redirect_stderr = true stopsignal = QUIT I'm sure I'm missing some minor detail, but I'm unable to notice it. Would appreciate any suggestions.

  • Debugging Samba/CUPS printer sharing with Windows

    - by mrdrbob
    I've got a HP Deskjet hooked up to a Slackware 12.2 box. I've got CUPS set up and can print a test page from the box just fine. I've also got Samba set up and have a couple file shares that work fine. I'm trying to share that HP Deskjet out via Samba, but I can't get it to show up in any Windows system. I see the server and its file shares in Windows networking, but when I open the Printers, no printer shows up. Running net view \\servername from the command line lists the file shares, but no printers. Here's the pertinent part of my smb.conf, if that helps: [global] workgroup = HOMENET security = share hosts allow = 192.168.1. 192.168.2. 127. load printers = yes printcap name = cups printing = cups log file = /var/log/samba.%m max log size = 50 [printers] comment = All Printers path = /var/spool/samba browseable = no public = yes writable = no printable = yes guest only = yes Can anyone give me some pointers as to where to start looking for potential causes? Update: Running testparm shows no errors. Here's the output (minus the file shares): [global] workgroup = HOMENET security = SHARE log file = /var/log/samba.%m max log size = 50 printcap name = cups hosts allow = 192.168.1., 192.168.2., 127.

  • Hard drive failed, suspected filesystem corruption, still cannot salvage any data from harddrive

    - by Hippy-Head
    Firstly, I am terribly sorry if this is a duplicate, but I couldn't find a similar issue to mine, so here goes. I have a 1TB hdd bought around 8 months ago used as backup hard drive. I have not used the drive for a period of time whatsoever, and when I was trying to get back to some files on it, it was completely wiped just like that. At first it would not boot I tried everything from command line chkdsk and filesystem recovery software to rebuilt it. After a few attempts I managed to initialize it, at that time it was an achievement. The problems started when I tried to recover the data inside, I have used A LOT of software free and commercial software on both Mac and Windows, with the help of cmd or Terminal commands, however no data of any kind was recovered, even after leaving it thoroughly scan for around 9-10 hours all night sometimes longer, with no results at all. I am somewhat desperate, I am usually good at retrieving data from corrupt hard drives, but this is not the case. Call me paranoid, but I do not want to give it to someone to fix it for me, as I have a lot of photos and personal stuff that I do not want anyone to see.

  • How do you install .net4 on a Server 2008 r2 machine through psremoting in powershell?

  • Redis 2.0.3 would not let go of deleted appendonly.aof file after BGREWRITEAOF

    - by Alexander Gladysh
    Ubuntu 10.04.2, Redis 2.0.3 (more details at the end of the question). My AOF file for Redis is getting too large, to the point where it soon would threaten to take whole free disk space on my small-HDD VPS box: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda 32G 24G 6.7G 78% / $ ls -la total 3866688 drwxr-xr-x 2 redis redis 4096 2011-03-02 00:11 . drwxr-xr-x 29 root root 4096 2011-01-24 15:58 .. -rw-r----- 1 redis redis 3923246988 2011-03-02 00:14 appendonly.aof -rw-rw---- 1 redis redis 32356467 2011-03-02 00:11 dump.rdb When I run BGREWRITEAOF, the AOF file shrinks, but disk space is not freed: $ ls -la total 95440 drwxr-xr-x 2 redis redis 4096 2011-03-02 00:17 . drwxr-xr-x 29 root root 4096 2011-01-24 15:58 .. -rw-rw---- 1 redis redis 65137639 2011-03-02 00:17 appendonly.aof -rw-rw---- 1 redis redis 32476167 2011-03-02 00:17 dump.rdb $ df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda 32G 24G 6.7G 78% / Sure enough, Redis is still holding the deleted file: $ sudo lsof -p6916 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME ... redis-ser 6916 redis 7r REG 202,0 3923957317 918129 /var/lib/redis/appendonly.aof (deleted) ... redis-ser 6916 redis 10w REG 202,0 66952615 917507 /var/lib/redis/appendonly.aof ...

  • Intel DriverInstall issue on HP ProLiant server DL580G5

    - by TomTom
    Given: A HP ProLiant server to be used for Hyper-V server (R 2) Problem: The server has a HP NC364T quad port card, which actually is an Intel 1000 Pro adapter. We are stuck getting this adapter properly working. We need to get it working with: 2 trunks of 2 ports each one of them fully vlan "aware" (without filtering anything - so that Hyper-V can do the VLAN filtering). So far we did: Install the server Install latest PSP. Problem here - tool does not work to set up teaming. We tried to install the latest ProWin pack from Intel - the drivers there are a LOT more current (26th of Marrch 2010, 9.13.41.0). The intalled driver (Microsoft) is ancient (march 2009, 9.13.4.10) A driver update fails both on command line (pnputil) as well as the PortLock device manager executable. No informatoin is provided. the ANS toolset can not create teams (fails with error - again, no reason provided), I know of no logs and the event log has no information either. Questions: What are the best drivers to use? How do we actually install them? How can we then set up teaming and how do we set up the VLAN behavior wanted?

  • Locating memory leak in Apache httpd process, PHP/Doctrine-based application

    - by Sam
    I have a PHP application using these components: Apache 2.2.3-31 on Centos 5.4 PHP 5.2.10 Xdebug 2.0.5 with Remote Debugging enabled APC 3.0.19 Doctrine ORM for PHP 1.2.1 using Query Caching and Results Caching via APC MySQL 5.0.77 using Query Caching I've noticed that when I start up Apache, I eventually end up 10 child processes. As time goes on, each process will grow in memory until each one approaches 10% of available memory, which begins to slow the server to a crawl since together they grow to take up 100% of memory. Here is a snapshot of my top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1471 apache 16 0 626m 201m 18m S 0.0 10.2 1:11.02 httpd 1470 apache 16 0 622m 198m 18m S 0.0 10.1 1:14.49 httpd 1469 apache 16 0 619m 197m 18m S 0.0 10.0 1:11.98 httpd 1462 apache 18 0 622m 197m 18m S 0.0 10.0 1:11.27 httpd 1460 apache 15 0 622m 195m 18m S 0.0 10.0 1:12.73 httpd 1459 apache 16 0 618m 191m 18m S 0.0 9.7 1:13.00 httpd 1461 apache 18 0 616m 190m 18m S 0.0 9.7 1:14.09 httpd 1468 apache 18 0 613m 190m 18m S 0.0 9.7 1:12.67 httpd 7919 apache 18 0 116m 75m 15m S 0.0 3.8 0:19.86 httpd 9486 apache 16 0 97.7m 56m 14m S 0.0 2.9 0:13.51 httpd I have no long-running scripts (they all terminate eventually, the longest being maybe 2 minutes long), and I am working under the assumption that once each script terminates, the memory it uses gets deallocated. (Maybe someone can correct me on that). My hunch is that it could be APC, since it stores data between requests, but at the same time, it seems weird that it would store data inside the httpd process. How can I track down which part of my app is causing the memory leak? What tools can I use to see how the memory usage is growing inside the httpd process and what is contributing to it?

  • Joining an Ubuntu 14.04 machine to active directory with realm and sssd

    - by tubaguy50035
    I've tried following this guide to set up realmd and sssd with active directory: http://funwithlinux.net/2014/04/join-ubuntu-14-04-to-active-directory-domain-using-realmd/ When I run the command realm –verbose join domain.company.com –user-principal=c-u14-dev1/[email protected] –unattended everything seems to connect.

  • Start and shutdown tomcat via ssh

    - by bxshi
    Updated I find out that the path of jdk it using is wrong. eval: 1: /opt/Java/jdk1.6.0_25/jre/bin/java: not found the Java should be lower case java, how is that happen? When I run this script directly on server, it is just okay. I'm trying to start or shutdown tomcat via a remote client. On my server, I've got 3 different tomcat: tomcat1, tomcat2, and tomcat3. Firstly, I've tried to run tomcat_path/bin/shutdown.sh to stop it via ssh, and the command is ssh [email protected] "cd /home/jake/tomcat2/bin;exec bash ./shutdown.sh" both " and ' are tried, but do not work, the output is eval: 1: /opt/Java/jdk1.6.0_25/jre/bin/java: not found it seems that the shell script runs on my local client, because on server it has this file. Is there any way to run a shell script on remote server correctly? updated I've run ssh [email protected] "sh -x /home/jake/tomcat/bin/shutdown.sh > /home/jake/tomcat.log 2>&1" and the output in tomcat.log is : + PRG=/home/jake/tomcat/bin/shutdown.sh + [ -h /home/jake/tomcat/bin/shutdown.sh ] + dirname /home/jake/tomcat/bin/shutdown.sh + PRGDIR=/home/jake/tomcat/bin + EXECUTABLE=catalina.sh + [ ! -x /home/jake/tomcat/bin/catalina.sh ] + exec /home/jake/tomcat/bin/catalina.sh stop eval: 1: /opt/Java/jdk1.6.0_25/jre/bin/java: not found

  • Ubuntu 10.04 Keyboard and Mouse Freezing Problem

    - by nitbuntu
    I had a partition setup with Windows XP and Ubuntu 8.04 dual booting. I recently upgraded to Ubuntu 10.04 by installing fresh from CD but leaving the previous /home folder as is. Things seemed to be working fine, but started finding that my mouse and keyboard were freezing. After a quick search on the internet, I found the following suggestions as shown here:- Ubuntu Forums Here the suggestion was to:- Edit /etc/default/grub, go to the line that begins like: GRUB_CMDLINE_LINUX_DEFAULT= Change it to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" After that, run this command: sudo update-grub and Reboot This seemed to have resolved the issue but after a couple of days I again find my mouse and keyboard freezing. I also find that my parallel port printer had also stopped working. I have saved the output of dmesg and my syslog. The first can be viewed here but the syslog had too many characters, so if someone can suggest an alternative to freetexthost, I can post it there. Moreover, if there is any other information that should be provided, do let me know. I do hope we can get to the bottom of this issue. Thank you in advance for any help that could be provided.

  • package issue with ubuntu 10.10 and passenger requirements

    - by user368937
    I'm trying to get Passenger working with Ubuntu 10.10 and I'm running into a problem. It seems that the passenger installer is not recognizing the virtual package. I'm getting this error: Code: passenger-install-apache2-module ... * OpenSSL support for Ruby... not found ... And then it says, run this: * To install OpenSSL support for Ruby: Please run apt-get install libopenssl-ruby as root. When I run the above command, it refers to the libruby package: sudo apt-get install libopenssl-ruby Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'libruby' instead of 'libopenssl-ruby' libruby is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 43 not upgraded. When I look at the details for libruby, it says it provides libopenssl-ruby: Code: Provides: libbigdecimal-ruby, libcurses-ruby, libdbm-ruby, libdl-ruby, libdrb-ruby, liberb-ruby, libgdbm-ruby, libiconv-ruby, libopenssl-ruby, libpty-ruby, libracc-runtime-ruby, libreadline-ruby, librexml-ruby, libsdbm-ruby, libstrscan-ruby, libsyslog-ruby, libtest-unit-ruby, libwebrick-ruby, libxmlrpc-ruby, libyaml-ruby, libzlib-ruby And when I rerun the passenger installer, it gives the same error: Code: passenger-install-apache2-module ... * OpenSSL support for Ruby... not found ... Let me know if you need more info. How do I fix this?

  • SOCKS5 proxy only, git wants to use ssh to xx.xx.xx.xx - forward? - mac os

    - by AlexAtNet
    I have SOCKS5 proxy configured and want to work with the git repository, originally cloned from ssh:... So when it tries to connect the error "Network is unreachable" appears. There are a few possible solutions: Use GIT URL rewriting and use https:// with proxy option. Probably should work well for github repositories. Use port forwarding and something like iptables/ipfw to rewrite address xx.xx.xx.xx:22 to 127.0.0.1:10yyy I'm trying to do #2. I have limited knowledge in this area, but know that I should use something like iptables. But then I discovered that on a Mac I should use ipfw. And then in the ipfw man page it told me "This utility is DEPRECATED. Please use pfctl(8) instead". So what I want to do is to rewrite xx.xx.xx.xx:22 to 127.0.0.1:10yyy and remove this rewriting. As I read, the pf.conf line should be rdr proto tcp from 127.0.0.1 to xx.xx.xx.xx port 22 -> 127.0.0.1 port 10yyy But how to add (and remove) this rule from command line?
