  • FTP Server vsftpd change ftp:nogroup

    - by pygorex1
    I'm running vsftpd using the Debian Lenny package. ftp:nogroup is the user/group that uploads files and owns uploaded files. However, a problem is arising - another process is also writing files to the FTP directory as myprocess:mygroup with restrictive file permissions, preventing vsftpd from overwriting the myprocess authored files. Is it possible to tell vsftpd to use a different user/group for uploading files? (preferably as myprocess:mygroup or ftp:mygroup)

  • pdftotext not outputting hebrew characters

    - by Ofri Raviv
    I'm using Xpdf's pdftotext to get the text out of some hebrew pdf files on Ubuntu. On my local machine this worked fine. I then tried to do it on another machine and the hebrew characters don't show up in the text file. I verified that I have the language package (see below why I think so). Where else can I look for the problem? >> tail -2 /etc/xpdf/xpdfrc include /etc/xpdf/includes >> cat /etc/xpdf/includes # This file was automatically generated by /usr/sbin/update-xpdfrc. # Instead, add or remove files in /etc/xpdf/ then run # /usr/sbin/update-xpdfrc to regenerate this file. include /etc/xpdf/xpdfrc-latin2 include /etc/xpdf/xpdfrc-thai include /etc/xpdf/xpdfrc-greek include /etc/xpdf/xpdfrc-turkish include /etc/xpdf/xpdfrc-arabic include /etc/xpdf/xpdfrc-hebrew include /etc/xpdf/xpdfrc-cyrillic >> cat /etc/xpdf/xpdfrc-hebrew #----- begin Hebrew support package (2003-feb-16) unicodeMap ISO-8859-8 /usr/share/xpdf/hebrew/ISO-8859-8.unicodeMap unicodeMap Windows-1255 /usr/share/xpdf/hebrew/Windows-1255.unicodeMap #----- end Hebrew support package >> ls /usr/share/xpdf/hebrew/ ISO-8859-8.unicodeMap Windows-1255.unicodeMap

  • Centos 5.5 [Read-only file system] issue after rebooting

    - by canu johann
    I have a virtual server under centos 5.5 (hosted by a japanese company called sakura ) Since yesterday, connection through ssh couldn't be established.

  • SFTP ChRoot result in broken pipe

    - by Patrick Pruneau
    I have a website that I want to add some restricted access to a sub-folder. For this, I've decided to use CHROOT with SFTP (I mostly followed this link : http://shapeshed.com/chroot_sftp_users_on_ubuntu_intrepid/) For now, I've created a user (sio2104) and a group (magento).After following the guide, my folder list look like this : -rw-r--r-- 1 root root 27 2012-02-01 14:23 index.html -rw-r--r-- 1 root root 21 2012-02-01 14:24 info.php drwx------ 15 root root 4096 2012-02-25 00:31 magento As you can see, i've chown root:root the folder magento I wanted to jail-in the user and ...everything else by the way. Also in the magento folder, I chown sio2104:magento everything so they can access what they want. Finally, I've added this to sshd_config file : #Subsystem sftp /usr/lib/openssh/sftp-server Subsystem sftp internal-sftp Match Group magento ChrootDirectory /usr/share/nginx/www/magento ForceCommand internal-sftp AllowTCPForwarding no X11Forwarding no PasswordAuthentication yes #UsePAM yes And the result is...well, I can enter my login, password and it's all finished with a "broken pipe" error. $ sftp [email protected] [....some debug....] [email protected]'s password: debug1: Authentication succeeded (password). Authenticated to 10.20.0.50 ([10.20.0.50]:22). debug1: channel 0: new [client-session] debug1: Requesting [email protected] debug1: Entering interactive session. Write failed: Broken pipe Connection closed Verbose mode gives nothing to help. Anyone have an idea of what I've done wrong? If I try to login with ssh or sftp with my personnal user, everything works fine.

  • bash script - spawn, send, interact - commands not found error

    - by Sandeepan Nath
    I my shell script, I am trying to remove password prompt for scp command (as given in http://stackoverflow.com/questions/459182/using-expect-to-pass-a-password-to-ssh/459225#459225) and this is what I have so far :- #!/usr/bin/expect spawn scp $DESTINATION_PATH/exam.tar $SSH_CREDENTIALS':/'$PROJECT_INSTALLATION_PATH expect "password:" send $sshPassword"\n"; interact On running the script, I am getting errors spawn: command not found send: command not found interact: command not found I was also getting error expect: command not found also, then I realised the path to expect was not correct and expect was not installed at all. So, I did yum install expect, corrected the path and the error was gone. But not able to remove the other 3 errors still.

  • lighttpd: weird behavior on multiple rewrite rule matches

    - by netmikey
    I have a 20-rewrite.conf for my php application looking like this: $HTTP["host"] =~ "www.mydomain.com" { url.rewrite-once += ( "^/(img|css)/.*" => "$0", ".*" => "/my_app.php" ) } I want to be able to put the webserver in kind of a "maintenance" mode while I update my application from scm. To do this, my idea was to enable an additional rewrite configuration file before this one. The 16-rewrite-maintenance.conf file looks like this: url.rewrite-once += ( "^/(img|css)/.*" => "$0", ".*" => "/maintenance_app.php" ) Now, on the maintenance page, I have a logo that doesn't get loaded. I get a 404 error. Lighttpd debug says the following: 2012-12-13 20:28:06: (response.c.300) -- splitting Request-URI 2012-12-13 20:28:06: (response.c.301) Request-URI : /img/content/logo.png 2012-12-13 20:28:06: (response.c.302) URI-scheme : http 2012-12-13 20:28:06: (response.c.303) URI-authority: localhost 2012-12-13 20:28:06: (response.c.304) URI-path : /img/content/logo.png 2012-12-13 20:28:06: (response.c.305) URI-query : 2012-12-13 20:28:06: (response.c.300) -- splitting Request-URI 2012-12-13 20:28:06: (response.c.301) Request-URI : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.302) URI-scheme : http 2012-12-13 20:28:06: (response.c.303) URI-authority: localhost 2012-12-13 20:28:06: (response.c.304) URI-path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.305) URI-query : 2012-12-13 20:28:06: (response.c.349) -- sanatising URI 2012-12-13 20:28:06: (response.c.350) URI-path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (mod_access.c.135) -- mod_access_uri_handler called 2012-12-13 20:28:06: (response.c.470) -- before doc_root 2012-12-13 20:28:06: (response.c.471) Doc-Root : /www 2012-12-13 20:28:06: (response.c.472) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.473) Path : 2012-12-13 20:28:06: (response.c.521) -- after doc_root 2012-12-13 20:28:06: (response.c.522) Doc-Root : /www 2012-12-13 20:28:06: (response.c.523) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.524) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.541) -- logical -> physical 2012-12-13 20:28:06: (response.c.542) Doc-Root : /www 2012-12-13 20:28:06: (response.c.543) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.544) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.561) -- handling physical path 2012-12-13 20:28:06: (response.c.562) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.618) -- file not found 2012-12-13 20:28:06: (response.c.619) Path : /www/img/content/logo.png, /img/content/logo.png Any clue on why lighttpd matches both rules (from my application rewrite config and from my maintenance rewrite config) and concatenates them with a comma - that doesn't seem to make any sense?! Shouldn't it stop after the first match with rewrite-once?

  • Explanation of command to uppercase the first letter of a filename

    - by hazielquake
    I'm trying to learn to rename files with the command line, and after browsing around a lot of pages I finally found a command that uppercases the first letter of a file, but the problem is that I want to understand the meaning of each command. The command is: for i in *; do new=`echo "$i" | sed -e 's/^./\U&/'`; mv "$i" "$new";done I understand the 'for' kinda... but not the 'echo' or '`' and especially the sed command. if someone has a little patience to explain the meaning of each thing that'd be awesome! Thanks!

  • How to query a DHCP server to get the local DNS serves

    - by Dan Berlyoung
    I have a ClarkConnect (CentOS based) box running as my home router on a RR connection. I had the DNS servers set up to use Google's DNS server. I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a)reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b)calling their T/S (kill me now!). Is there a command line tool/command I can use to query the DHCP server on the external NIC to see what DNS servers it would set me up with w/o munging my existing setup?

  • bash code in rc.local not excuting after bootup

    - by mrTomahawk
    Does anyone know why a system would not execute the script code within rc.local on bootup? I have a post configuration bash script that I want to run after the initial install of VMware ESX (Red Hat), and for some reason it doesn't seem to execute. I have the setup to log its start of execution and even its progress so that I can see how far it gets in case it fails at some point, but even when I look at that log, I am finding that didn't even started the execution of the script code. I already checked to see that script has execution permissions (755), what else should I be looking at? Here is the first few lines of my code: #!/bin/sh echo >> /tmp/configLog "" echo >> /tmp/configLog "Entering maintenance mode"

  • How to make working TFTP server on CentOS 6.2

    - by Dima
    I'm trying to setup TFTP server on CentOS 6.2. The /etc/xinet.d/tftp configuration file is the following: service tftp { disable = no socket_type = dgram protocol = udp wait = yes user = root server = /usr/sbin/in.tftpd server_args = -s /tftpboot -vvv per_source = 11 cps = 100 2 flags = IPv4 } The selinux and firewall are disabled. The /etc/hosts.allow and /etc/hosts.deny files are empty. When I'm trying to get a file from the TFTP server, the file transfer always failed and I see the following errors into /var/log/messages Jul 11 03:16:53 localhost xinetd[4155]: xinetd Version 2.3.14 started with libwrap loadavg labeled-networking options compiled in.

  • Millions of files in php's tmp error - how to delete?

    - by Jonatan Littke
    Hey. I've got a tmp-folder with 14 million php session files in my home directory. At least that's what I think it is, it's not like I could ls it or anything. How can I empty this folder? I've tried using find with the -exec rm {} \; commands but that didn't work. ls 'sess_0*' | xargs rm did neither. I'm currently running rm -rf tmp but after two hours the folder appears to be the same size. REFERENCE INFO: I suddenly encountered an error where SESSIONS could no longer be written to disk: [Mon Apr 19 19:58:32 2010] [warn] mod_fcgid: stderr: PHP Warning: Unknown: open(/var/www/clients/client1/web1/tmp/sess_8e12742b62aa68a3f9476ec80222bbfb, O_RDWR) failed: No space left on device (28) in Unknown on line 0 [Mon Apr 19 19:58:32 2010] [warn] mod_fcgid: stderr: PHP Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/www/clients/client1/web1/tmp) in Unknown on line 0 I ran: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/md0 457G 126G 308G 29% / tmpfs 1.8G 0 1.8G 0% /lib/init/rw udev 10M 664K 9.4M 7% /dev tmpfs 1.8G 0 1.8G 0% /dev/shm But as you can see, the disk isn't full. So I had a look in the syslog which says the following 20 times per second: kernel: [19570794.361241] EXT3-fs warning (device md0): ext3_dx_add_entry: Directory index full! This led me thinking to a full folder, obviously, but since my web folder only has 60k files (having counted them), I guessed it was the tmp folder (the local one, for this instance of php) that messed things up. Some commands I ran: $ sudo ls sess_a* | xargs rm -f bash: /usr/bin/sudo: Argument list too long find . -exec rm {} \; rm: cannot remove directory '.' find: cannot fork: Cannot allocate memory I'm running Debian Lenny, php5, ISPConfig, SuEXEC and Fast-CGI.

  • Oracle 10.2.0.1 --> 10.2.0.4 patchset errors on Advanced Queuing tables. Serious or not?

    - by hurfdurf
    We're running Oracle on RHEL 5.4 64-bit. We recently did an upgrade from 10.2.0.1 to 10.2.0.4. Many errors were generated during the upgrade (sample listed below from trace.log) but during application testing afterward everything seemed fine (clean EXP, inserts, updates, deletes, etc.). The errors look like they are all related to Advanced Queuing tables and views. We are not using replication at all, this is a simple single instance db. ORA-24002: QUEUE_TABLE SYS.AQ_EVENT_TABLE does not exist ORA-24032: object AQ$_AQ_SRVNTFN_TABLE_T exists, index could not be created ORA-24032: object AQ$_ALERT_QT_S exists, index could not be created for queue ORA-06512: at "SYS.DBMS_AQADM_SYSCALLS", line 117 ORA-06512: at "SYS.DBMS_AQADM_SYS", line 5116 Is this worth worrying about, and if so, how do I go about cleaning up/recreating the corrupted and/or missing objects?

  • Permanently mount multiple directories from different disks under /

    - by piotrek
    I have SSD and HDD. Some directories like /var, /srv and /tmp should be on HDD, while /boot, /usr and /lib on SSD. But do I have to create separate partition for every single directory? I want to have 2 or so partitions. One for each disk and distribute directories as needed. Is it possible and how? I've heard about symlinks, mount --bind, mhddfs but: symlinks are treated differently by tools like cp, so I'm not sure if it's safe to have main system directories symlinked I have no idea how can I use mount --bind or mhddfs in fstab

  • Motherboard/PSU crippling USB and Sata

    - by celebdor
    I very recently bought a new desktop computer. The motherboard is: Z77MX-D3H and the power supply is ocz zs series 550w. The issue I have is that once I boot to the operating system (I have tried with fedora and Ubuntu with kernels 2.6.38 - 3.4.0), my hard drive (2.5" Magnetic) occasionally makes a power switch noise and it resets. Needless to say, when this drive is the OS drive, the OS crashes. I also have a SSD that works fine with the same OS configurations, but if I have the magnetic hard drive attached as second drive, it works erratically and the reconnects result in corrupted data. I also noticed that whenever I plug an external hard drive USB2.0 or USB3.0 to the computer the issue with the reconnects is even worse: [ 52.198441] sd 7:0:0:0: [sdc] Spinning up disk...

Also the issue of the usb reconnects is less frequent if the hard drive is plugged before I switch on the computer. Does anybody have some advice as to what I could do? Which is the faulty part/s that I should replace? As for me, I really don't know if to point my finger to the PSU or the Motherboard (I have updated to the latest firmware and checked the BIOS settings several times). EDIT: The reconnects are happening both in the Sata connected drives and the USBX connected drives.

  • synchronous network audio

    - by intuited
    I'd like to have an audio transmission shared among computers on a LAN. Although there are various systems to do this -- shoutcast/icecast, pulseaudio, etc. -- I'm not aware of any that provide synchronization. I'd like to have different computers in the house playing the same audio, and have the same sample playing at the same time. Is there a system which can do this?

  • Redhat doesn't set my desired hostname on reboot

    - by tomdee
    I have a redhat (EL5) server that I need to change the hostname on. I'm trying to put it back into a known state to help with server provisioning activities. As part of changing the hostname, I'm updating /etc/sysconfig/network and /etc/hosts. I also have an explicit call to hostname. My desired state is that the server thinks its hostname is "localhost". And a call to "hostname" returns "localhost". The problem I'm having is that when I reboot, the hostname is reverted to "localhost.companyname.com" which is not what I want. How do I ensure that the hostname is set up as just "localhost" when I reboot? My /etc/sysconfig/network file contains: NETWORKING=yes HOSTNAME=localhost GATEWAY=123.123.123.123 #I do have a proper IP address here My /etc/hosts file contains: 127.0.0.1 localhost.localdomain localhost 172.21.1.1 localhost.companyname.com localhost

  • How to query a DHCP server to get the local DNS serves

    - by Dan Berlyoung
    I have a ClarkConnect (CentOS based) box running as my home router on a RR connection. I had the DNS servers set up to use Google's DNS server. I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a)reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b)calling their T/S (kill me now!). Is there a command line tool/command I can use to query the DHCP server on the external NIC to see what DNS servers it would set me up with w/o munging my existing setup?

  • Supervisor VS cronjob

    - by Guandalino
    Actually I'm using supervisor to monitor a process and restart it when it stops for some reason. The problem is that in case of a supervisor crash the process stops get monitored. So I thought to schedule a cronjob to check supervisor is running, and eventually restart it. The next thing I'm considering is to get rid of supervisor and check my process directly from the cronjob. I read that sometimes supervisor uses too much memory (to be verified, though). What are the pros in having supervisor VS cronjob monitoring the process?

  • Excluding child processes from ps

    - by stefpet
    Background: To reload app configuration I need to kill -HUP the parent processes' PIDs. To find PIDs I currently use ps auxf | grep gunicorn with the following example output: $ ps auxf | grep gunicorn stpe 4222 0.0 0.2 64524 11668 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 4225 0.0 0.4 76920 16332 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 4226 0.0 0.4 76932 16340 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 4227 0.0 0.4 76940 16344 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 4228 0.0 0.4 76948 16344 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 4229 0.0 0.4 76960 16356 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 4230 0.0 0.4 76972 16368 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 4231 0.0 0.4 78856 18644 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 4232 0.0 0.4 76992 16376 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 5685 0.0 0.0 22076 908 pts/1 S+ 11:50 0:00 | \_ grep --color=auto gunicorn stpe 5012 0.0 0.2 64512 11656 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py stpe 5021 0.0 0.4 77656 17156 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py stpe 5022 0.0 0.4 77664 17156 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py stpe 5023 0.0 0.4 77672 17164 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py stpe 5024 0.0 0.4 77684 17196 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py stpe 5025 0.0 0.4 77692 17200 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py stpe 5026 0.0 0.4 77700 17208 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py stpe 5027 0.0 0.4 77712 17220 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py stpe 5028 0.0 0.4 77720 17220 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py Based on the above I see that it is 4222 and 5012 I need to HUP. Question: How can I exclude the child processes and only get the parent process (please note however that the processes I want do also have a parent (e.g. bash) that I'm uninterested with)? Using a regexp with grep on how much indentation there is in the ascii tree feels dirty. Is there a better way? Example: The desired output would be something like this. stpe 4222 0.0 0.2 64524 11668 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 5012 0.0 0.2 64512 11656 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py This would be easily parseable to be able to automatically find the PIDs in a script that does the HUPing which is the goal.
