  • Removing port forwardings programmatically on a ControlMaster SSH session

    - by aef
    Quite a while ago I got an answer telling me how to add a port-forwarding on a running SSH ControlMaster process. To know that helps a lot, but I'm still missing a way to remove such a port forwarding after I don't need that anymore. As far as I know, you can do that through the internal command key sequence on normal connections, this seems to be disabled for ControlMaster clients. Even if that would be possible I would need a solution which I can automatize with scripts, which is surely not so easy this way. Is there a way to do it? And is it easily automatizable?

  • what is uninstall procedure for software installed via "make install" on CentOS 6.2

    - by gkdsp
    I installed OCILIB on my CentOS 6.2 server some time ago, and now I want to install a newer version. The vendor requires an uninstall, but doesn't provide instructions. I'm guessing that's because it's trivial for people with a Linux background. http://orclib.sourceforge.net/doc/html/group_g_install.html If I installed this software using: step 1: # ./configure --with-oracle-headers-path=/usr/include/oracle/11.2/client64 --with-oracle-lib-path=/usr/lib/oracle/11.2/client64/lib step 2: # make step 3: # su root step 4: # make install step 5: # gcc -g -DOCI_IMPORT_LINKAGE -DOCI_CHARSET_ANSI -L/usr/lib/oracle/11.2/client64/lib -lclntsh -L/usr/local/lib -locilib conn.c -o conn How would I go about uninstalling this? I tried following this http://www.cyberciti.biz/faq/delete-uninstall-software-linux-commands/ but nothing was found on my disk using rpm -qa *oci* or yum list *oci*. Maybe since it wasn't installed with yum or rpm then I shouldn't expect either of these to find it. Are there generic instructions for uninstalling software on Linux that I could use, or do the instructions really depend on the specific software? Any help much appreciated.

  • Linux NIC Bonding Issue (CentOS 4 / RHEL 3)

    - by jinanwow
    I am having an issue with bonding NICs on CentOS 4. It appears the bonding driver does work, but it is stuck in round-robin mode and I am trying to get to active-backup. The current config is: ifcfg-bond0 DEVICE=bond0 IPADDR=192.168.204.18 NETMASK=255.255.255.0 ONBOOT=yes BOOTPROTO=none USERCTL=no TYPE=Bonding BONDING_OPTS="mode=1 miimon=100" ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none ONBOOT=yes TYPE=Ethernet MASTER=bond0 SLAVE=yes ifcfg-eth3 DEVICE=eth3 ONBOOT=yes BOOTPROTO=none TYPE=Ethernet MASTER=bond0 SLAVE=yes cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v2.6.3-rh (June 8, 2005) Bonding Mode: load balancing (round-robin) MII Status: up MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth1 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:17:a4:8f:94:b1 Slave Interface: eth3 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:1b:21:56:b8:69 cat /etc/modprobe.conf alias eth0 tg3 alias eth1 tg3 alias eth3 e1000 alias eth2 e1000 alias bond0 bonding options bond0 mode=1 miimon=100 I have tried moving the bonding information out of the ifcfg-bond0 into the modprobe configuration file. It seems that it is stuck in RR and I am trying to get it into the Active-backup (mode 1) state. Any ideas what would be causing this issue?

  • List all symbolic links on a directory

    - by Mathias
    Hey, a short question: is it possible to list all symbolic links onto a directory other than running a find over the whole filesystem? Background: I have a directory containing a lot of different versions of a library and I'd like to do some cleanup work and delete the versions which weren't used in any projects. Thanks, Mathias

  • Vmware server - 3d graphics upgrade like WKS 7 and vmware player

    - by jimbo45
    Hi all Anybody have an idea as to when VMWARE SERVER will have an upgrade to support 3-d graphics etc. I have created some W7 VM's under WKS7 and an upgraded vmware tools -- the W7 VM's run full aero etc. I believe that vmware tools and graphics for VM's running under vmware server are at the WKS 6.5 level -- hence problems can occur. Any info on an upgrade. Cheers jimbo

  • Autoloading Development or Production configs (best practices)

    - by Xeoncross
    When programming sites you usually have one set of config files for the development environment and another set for the production server (or one file with both settings). I am assuming all projects should be handled by version control like git or svn. Manual file transfers (like FTP) is wrong on so many levels. How you enable/disable the correct settings (so that your system knows which ones to use) is a problem for me. Each system I work on just kind of jimmy-rigs a solution. Below are the 3 methods I know of and I am hoping that someone can submit a more elegant solutions. 1) File Based The system loads a folder structure based on the URL requested. /site.com /site.fakeTLD /lib index.php For example, if the url is http://site.com then the system loads the production config files located in the site.com folder. However, if I'm working on the site locally I visit http://site.fakeTLD to work on the local copy of the site. To setup this I edit my hosts file and add site.fakeTLD to point to my own computer (127.0.0.1/localhost) and then create a vhost in apache. So now I can work on the codebase locally and then push to the server without any trouble. The problem is that this is susceptible to a "host" injection attack. So someone loading site.com could set the host to site.fakeTLD and then the system would load my development config files instead of production. 2) Config Based The config files contain on section for development - and one for production. The problem is that each time you go to push your changes to the repo you have to edit the file to specify which set of config options should be used. $use = 'production'; //'development'; This leaves the repo open to human error should one of the developers forget to enable the right setting. 3) File System Check Based All the development machines have an extra empty file called "development.txt" or something. Each time the system loads it checks for this file - if found then it knows it is in development mode - if missing then it knows it is in production mode. Since the file is NEVER ADDED to the repo then it will never be pushed (and checked out) on the production machine. However, this just doesn't feel right and causes a slight slow down since all filesystem checks are slow.

  • Trying to use Nginx try_files to emulate Apache MultiViews

    - by Samuel Bierwagen
    I want a request to http://example.com/foobar to return http://example.com/foobar.jpg. (Or .gif, .html, .whatever) This is trivial to do with Apache MultiViews, and it seems like it would be equally easy in Nginx. This question seems to imply that it'd be easy as try_files $uri $uri/ index.php; in the location block, but that doesn't work. try_files $uri $uri/ =404; doesn't work, nor does try_files $uri =404; or try_files $uri.* =404; Moving it between my location / { block and the regexp which matches images has no effect. Crucially, try_files $uri.jpg =404; does work, but only for .jpg files, and it throws a configuration error if I use more than one try_files rule in a location block! The current server { block: server { listen 80; server_name example.org www.example.org; access_log /var/log/nginx/vhosts.access.log; root /srv/www/vhosts/example; location / { root /srv/www/vhosts/example; } location ~* \.(?:ico|css|js|gif|jpe?g|es|png)$ { expires max; add_header Cache-Control public; try_files $uri =404; } } Nginx version is 1.1.14.

  • Way to speed up load-balanced ssl using nginx?

    - by paulnsorensen
    So the setup for our website is 4 nodes running rails 3 and nginx 1 that all use the same GoDaddy certificate. Because we are a paid site, we have to maintain PCI-DSS compliance and thus have to use the more expensive SSL ciphers -- also we force SSL using Rack. I've recently switched over to Linode's NodeBalancer (which I've read is an HACluster), and we're not getting the performance we'd ideally like. From what I've read, it looks like terminating the SSL on the nodes using the high cipher is what is causing the poor performance, but I'd like to be thorough. Is there anything I can do? I've read about other ways to terminate the SSL before the NodeBalancer (like using stud), but I don't know enough about these solutions. We certainly don't want to do anything experimental or anything that has a single point of failure. If there really isn't anything I can do to speed up the SSL handshake, my alternative would be to support certain pages on Rails using a secure and insecure subdomain. I've found a few guides that walk through that, but my resulting question is in this situation, would it be better to have nginx handle forcing ssl on the secure subdomain instead of rails? Thanks!

  • Jboss unreachable/ slow behind apache with ajp

    - by Niels
    I have an linux server running with a JBoss Instance with apache2. Apache2 will use AJP connection to reverse proxy to JBoss. I found these messages in the apache error.log: [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header [error] ajp_read_header: ajp_ilink_receive failed [error] (120006)APR does not understand this error code: proxy: read response failed from 8.8.8.8:8009 (hostname) [error] (111)Connection refused: proxy: AJP: attempt to connect to 8.8.8.8:8009 (hostname) failed [error] ap_proxy_connect_backend disabling worker for (hostname) [error] proxy: AJP: failed to make connection to backend: hostname [error] proxy: AJP: disabled connection for (hostname)25 I googled around but I can't seem to find any related topics. There are people say this behavior can be caused by misconfigured apache vs jboss. Telling the max amount of connections apache allows are far greater then jboss, causing the apache connection to time out. But I know the app isn't used by thousands of simultaneous connections at the time not even hundreds of connections so I don't believe this could be a cause. Does anybody have an idea? Or could tell me how to debug this problem? I'm using these versions: Debian 4.3.5-4 64Bit Apache Version 2.2.16 JBOSS Version 4.2.3.GA Thanks

  • Multiple IPv6 addresses being assigned to single interface

    - by Steven Copestake
    I'm configuring a DHCP scope for IPv6, however all my clients are getting 2 or more IPv6 addresses assigned to the interface. I'm using fda8:6c3:ce53:a890:/64 as the prefix. The scope is on a machine running Windows Server 2008 R2 however I'm looking to roll it out on Server 2012 as well. My clients are getting the following: IPv6 Address. . . . . . . . . . . : 1024::1492:9288:7357:7d30(Preferred) IPv6 Address. . . . . . . . . . . : fda8:6c3:ce53:a890::1(Preferred) IPv6 Address. . . . . . . . . . . : fda8:6c3:ce53:a890:1492:9288:7357:7d30(Pr rred) Link-local IPv6 Address . . . . . : fe80::1492:9288:7357:7d30%10(Preferred) In this example there's no DHCP scope and the machine has a static IP of fda8:6c3:ce53:a890::1. With this in mind where are the 1024 address and the fda8:6c3:ce53:a890:1492:9288:7357:7d30 address coming from?

  • Linux: Force fsck of a read-only mounted filesystem?

    - by Timothy Miller
    I'm developing for a headless embedded appliance, running CentOS 6.2. The user can connect a keyboard, but not a monitor, and a serial console would require opening the case, something we don't want the user to have to do. This all pretty much obviates the possibility of using a recovery USB drive to boot from, unless all it does is blindly reimage the harddrive. I would like to provide some recovery facilities, and I have written a tool that comes up on /dev/tty1 in place of getty to provide these functions. One such function is fsck. I have found out how to remount the root and other file systems read-only. Now that they are read-only, it should be safe to fsck them and then reboot. Unfortunately, fsck complains to me that the filesystems are mounted and refuses to do anything. How can I force fsck to run on a read-only mounted partition? Based on my research, this is going to have to be something obscure. "-f" just means to force repair of a clean (but unmounted) partition. I need to repair a clean or unclean mounted partition. From what I read, this is something "only experts" should do, but no one has bothered to explain how the experts do it. I'm hoping someone can reveal this to me. BTW, I've noticed that e2fsck 1.42.4 on Gentoo will let you fsck a mounted partition, even mounted read-write, but it seems only to do so if fsck is run from a terminal, so it can ask the user if they're sure they want to do something so dangerous. I'm not sure if the CentOS version does the same thing, but it appears that fsck CAN repair a mounted partition, but it flatly refuses to when not run from a terminal. One last-resort option is for me to compile my own hacked fsck. But I'm afraid I'll mess it up in some unexpected way. Thanks! Note: Originally posted here.

  • Multiple subnets on isc-dhcp-server using ddns with bind9

    - by legioxi
    On my network I have two subnets: 10.100.1.0/24 - Wired/wireless 10.100.7.0/24 - VPN Both subnets are served by isc-dhcp-server running on a Debian VM. This same VM runs bind9 for my DNS. ISC-DHCP-SERVER is configured to use DDNS and update BIND9 with hosts/IPs. Everything runs great until a device drops off the wired/wireless network and pops onto the VPN. When connecting on the VPN, a DHCP lease is handed out on the new subnet but DDNS does not update BIND9. Since the device has A/TXT/PTR records it appears ISC-DHCP-SERVER won't switch them to the new IP. The logs show: Connect to wireless: Nov 6 20:55:13 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': adding an RR at 'demo-iphone.internal.mydomain.com' A Nov 6 20:55:13 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': adding an RR at 'demo-iphone.internal.mydomain.com' TXT Nov 6 20:55:13 core-server dhcpd: DHCPACK on 10.100.1.160 to FF:FF:FF:FF:FF:FF (demo-iphone) via eth0 Nov 6 20:55:13 core-server dhcpd: Added new forward map from demo-iphone.internal.mydomain.com to 10.100.1.160 Nov 6 20:55:13 core-server dhcpd: Added reverse map from 160.49.21.172.in-addr.arpa. to demo-iphone.internal.mydomain.com Switch to VPN: Nov 6 20:56:34 core-server dhcpd: DHCPOFFER on 10.100.7.101 to BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': update unsuccessful: demo-iphone.internal.mydomain.com: 'name not in use' prerequisite not satisfied (YXDOMAIN) Nov 6 20:56:34 core-server dhcpd: DHCPREQUEST for 10.100.7.101 (10.100.1.2) from BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server dhcpd: DHCPACK on 10.100.7.101 to BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': update unsuccessful: demo-iphone.internal.mydomain.com/TXT: 'RRset exists (value dependent)' prerequisite not satisfied (NXRRSET) Nov 6 20:56:34 core-server dhcpd: Forward map from demo-iphone.internal.mydomain.com to 10.100.7.101 FAILED: Has an address record but no DHCID, not mine. One thing to note is that the MAC of the device when connecting via VPN is the MAC of my Cisco ASA5512X and not the actual device. The ASA is relaying the DHCP request from the VPN client to the VM running ISC-DHCP-SERVER. Is there a way to get DDNS working in this scenario?

  • RDP Connection to XP from Windows 7 crashes part of XP

    - by Oliver Nelson
    I have some XP machines that my users RDP into. If I RDP into the machine from something other than a Windows 7 box, and then RDP into the machine with a Windows 7 box, the XP machines crash (not BSOD though). I get an event ID 1003 with these details: Error code 1000008e, parameter1 c0000005, parameter2 bf85b6b7, parameter3 b6149a88, parameter4 00000000. I have this happening on quite a few machines, and I can reliably reproduce it. I've found no way to fix it. If I only connect from Windows 7 machines, it never fails. Any suggestions? (I've checked color settings and basic RDP client settings, and they all seem to match between the Windows 7 Clients and the XP clients).

  • DFSR - What happens when one server gets maxed out?

    - by Jared
    What happens when one server in a DFSR pool maxes out its disk space? I am at the very beginning of my research in DFS/R and this struck me. I plan on implementing this on one server with RAID1 (160GB) and on another server with a RAID5 (500GB). What happens when my 1st server with 160GB disks, run out of space? Will it spill over to the 500GB server? Is it advisable at all to even have the RAID1 server in the DFSR pool? Because the RAID1 server is also my Domain Controller. Hope you guys can help me out here (OS are Win2k3R2)

  • How to prevent nginx from locking files on mounted samba partition in Centos 6

    - by Bruce Kirkpatrick
    I'm using nginx 1.3.8 inside a centos 6.3 virtualbox 4.2.4 virtual machine. The system is running the latest software available via yum update. The host OS is windows 7. The site files nginx is serving are on mounted samba partition, which is a folder on the host Windows system. I.e., inside linux, nginx paths are referring to /home/vhosts and this is mounted from D:\vhosts\ on windows. The samba partition is mounted as root with 777 privileges. /etc/fstab looks like this, but with real ip, username, password: //hostip/vhosts /home/vhosts cifs username=username,password=SECRETPASSWORD,uid=root,gid=root,file_mode=0777,dir_mode=0777,rw,_netdev 0 0 I.e. linux/nginx reads from the windows share, and not the opposite. in /etc/samba/smb.conf, I have tried to disable all samba locking features, but it seems to have no effect even after rebooting the virtual machine. locking=no share modes=no oplocks = no level2 oplocks = no kernel oplocks =no I'm receiving "Access is denied" errors in Windows or linux when attempting to overwrite the javascript file in windows that has been accessed at least once with nginx. If I run "service nginx reload", the lock is removed and I'm able to save the file. That's why I think it is nginx causing the lock. The same problem occurs with directories. However, that may be a different issue not related to the use of samba. I'm using samba so that I can manage the source code outside of the virtual machine. Also note that after I run "service nginx reload", the file I'm editing is actually automatically deleted from the windows host. SOLVED: I just reviewed my nginx.conf file. It appears the "open_file_cache" feature is what is causing the lock and deleted files. When I set this option to open_file_cache off;, My problem is resolved. I will repost as the answer when it allows me to do so.
