  • tmux -- any way to enable scrolling, but not selection?

    - by gatoatigrado
    I like that when mode-mouse is on in tmux, I can scroll through the buffer, but I don't like that I can't copy stuff to my OS clipboard by selecting it (as when tmux is disabled). Question: Is there any way to enable mouse scrolling, but not selection? I'm using KDE's konsole, if it matters. I've tried setting, set -g mouse-select-pane off set -g mouse-select-window off but no luck -- the only difference seems to be whether mode-mouse is on (tmux captures scrolling and selection) or off (tmux captures neither scrolling nor selection).

  • Windows 7: How to enable firewall disabled by global policy on a computer joined to a domain?

    - by kzen
    On a Windows 7 Enterprise 64-bit laptop joined to a corporate domain, the Windows Firewall is disabled by a global policy. Is there any way to enable the Windows Firewall in this scenario? The gpedit.msc setting Windows Firewall: Protect all network connections is inaccessible. EDIT: It appears that changing HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\gpsvc\Start value to 4 will disable the GPO and allow you to start the firewall and stop the bots from pushing cr*p to your computer... will check on Monday and if it works I'll confirm here in case someone else in my situation wonders upon this question... EDIT: It's probably better if I write a mock windows service not doing anything and name it according to what is expected to be on my box and than crete mock McCrappy executable and mock McCrappy folder structure and remove all the actual stuff... That would take a little time but would most certainly make my box completely stealthy...

  • Do HTTP reverse proxies typically enable HTTP Keep-Alive on the client side of the proxied connection and not on the server side?

    - by LostInComputer
    HAProxy has the ability to enable HTTP keep-alive on the client side (client <- HAProxy) but disable it on the server side (HAProxy <- server). Some of our clients connect to our web service via satellite so the latency is ~600ms and I think that by enabling keep-alive, it will speed things up a bit. Am I right? Is this supported by Nginx? Is this a widely implemented feature in other software and hardware load balancers? What else besides HAProxy?

  • How would I Enable FTP on Home PC (Win7)?

    - by jp2code
    In my home, all PCs connect through a small router. Some wired and some wireless. Our Media PC (HTPC) is controlled via a Media Center TV style remote, so managing files on it is tedious. I can access all of the files on the HTPC from my desktop PC, but moving a 6 GB file from \\HTPC\Folder1 to \\HTPC\Folder2 involves copying the data to the desktop and then transferring it back. If I were on the HTPC, this would likely be handled by a simple address change for the file (i.e. it would be done almost instantly). I'm thinking if I could get an FTP program to connect to the HTPC, I could simplify things ...but how do I enable that ability on the HPTC? Then, how would I go about connecting to the HTPC? Would I simply enter \\HTPC as the FTP address?

  • How to enable Postfix filter on OS X server (Lion) without getting overwritten?

    - by mjbraun
    I have a Postfix after-queue content filter that works fine on stock Ubuntu Postfix install. However, on a OS X Lion Server I'm testing out, I see this "auto-generated" language in the master.cf file: # ==== Begin auto-generated section ======================================== # This section of the master.cf file is auto-generated by the Server Admin # Mail backend plugin whenever mails settings are modified. smtp inet n - n - 1 postscreen smtpd pass - - n - - smtpd -o receive_override_options=no_address_mappings The problem is, to enable the filter the same area of the master.cf file has to be changed to have an entry like this: smtp inet n - - - - smtpd -o content_filter=mytest_filter:dummy So, it looks like the line would be blown away every I make a change in Server Admin. Is there a better place for me to put the call to the filter such that it's persistent? I appreciate any assistance and/or guidance!

  • How can I set clean urls (enable rewrite) if I don't have a domain ?

    - by Patrick
    In order to enable clean urls in Drupal, I add the lines below to the lighttpd configuration file. However I'm now working on a local server and I don't have a domain available. So I need to work with this address http://local.ip/Sites/mywebsite I've tried to replace ["host"] with ["socket"] and replace the domain with ip and subfolders (see address above), but unsuccessfully. How can I set the configuration file to set clean urls even if I don't have a domain ? thanks $HTTP["host"] =~ "(^|\.)mywebsite\.com" { server.document-root = "/var/www/sites/mywebsite" server.errorlog = "/var/log/lighttpd/mywebsite/error.log" server.name = "mywebsite.com" accesslog.filename = "/var/log/lighttpd/mywebsite/access.log" include_shell "./drupal-lua-conf.sh mywebsite.com" url.access-deny += ( "~", ".inc", ".engine", ".install", ".info", ".module", ".sh", "sql", ".theme", ".tpl.php", ".xtmpl", "Entries", "Repository", "Root" ) # "Fix" for Drupal SA-2006-006, requires lighttpd 1.4.13 or above # Only serve .php files of the drupal base directory $HTTP["url"] =~ "^/.*/.*\.php$" { fastcgi.server = () url.access-deny = ("") } magnet.attract-physical-path-to = ("/etc/lighttpd/drupal-lua-scripts/p-.lua") }

  • Why are my httpd mpm_prefork processes being reaped so quickly?

    - by Dan Pritts
    We've got a system running RHEL6, x64. We are using a local installation of apache 2.2.22 from source. we serve primarily: mod_perl applications (with a local installation of perl 5.16.0) tomcat applications proxied with mod_jk Here is some context; the main question is below. All of this talks to an Oracle backend. We are having issues with Oracle becoming unresponsive. We think this is because we're hitting the maximum process limit in oracle. We've upped the process limit, but now we are hitting memory pressure on the oracle server. We have tons of oracle sessions sitting idle. I can trace a bunch of them back to the httpd processes. We have mod_perl's Apache::DBI start up a new connection to the database with each httpd child that's spawned. We are concerned that these are not always getting closed out properly when the httpd's exit...and the httpd's are exiting very frequently. I know that it would be good to modify the mod_perl applications to use some better form of db connection pooling; we plan to pursue that but would like to solve our immediate problem sooner. So here's the main question. We are using the prefork MPM. The apache child processes are lasting at most a few minutes. Log analysis shows that each one is serving fewer than 50 clients before exiting; the last request each child serves is OPTIONS * HTTP/1.0 on some sort of internal connection; I'm under the impression that this is a "ping" from the master process. I've adjusted the MPM config as follows. I didn't want to raise MinSpareServers too high, because, after all, i'm trying to minimize the number of sessions to oracle. MinSpareServers 5 MaxSpareServers 30 MaxClients 150 MaxRequestsPerChild 10000 Right now we're serving 250-300 requests per minute. We've got 21 httpd's running, the eldest (other than the master, owned by root) being 3 minutes old. This rate of reaping of the apache children really seems excessive. What could be causing it? Apache was built with: $ ./configure --prefix=/opt/apache --with-ssl=/usr/lib --enable-expires --enable-ext-filter --enable-info --enable-mime-magic --enable-rewrite --enable-so --enable-speling --enable-ssl --enable-usertrack --enable-proxy --enable-headers --enable-log-forensic Apache config info: % /opt/apache/bin/httpd -V Server version: Apache/2.2.22 (Unix) Server built: Jul 23 2012 22:30:13 Server's Module Magic Number: 20051115:30 Server loaded: APR 1.4.5, APR-Util 1.4.1 Compiled using: APR 1.4.5, APR-Util 1.4.1 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/opt/apache" -D SUEXEC_BIN="/opt/apache/bin/suexec" -D DEFAULT_PIDLOG="logs/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="logs/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="conf/mime.types" -D SERVER_CONFIG_FILE="conf/httpd.conf" modules are compiled into apache rather than shared libs: % /opt/apache/bin/httpd -l Compiled in modules: core.c mod_authn_file.c mod_authn_default.c mod_authz_host.c mod_authz_groupfile.c mod_authz_user.c mod_authz_default.c mod_auth_basic.c mod_ext_filter.c mod_include.c mod_filter.c mod_log_config.c mod_log_forensic.c mod_env.c mod_mime_magic.c mod_expires.c mod_headers.c mod_usertrack.c mod_setenvif.c mod_version.c mod_proxy.c mod_proxy_connect.c mod_proxy_ftp.c mod_proxy_http.c mod_proxy_scgi.c mod_proxy_ajp.c mod_proxy_balancer.c mod_ssl.c prefork.c http_core.c mod_mime.c mod_status.c mod_autoindex.c mod_asis.c mod_info.c mod_cgi.c mod_negotiation.c mod_dir.c mod_actions.c mod_speling.c mod_userdir.c mod_alias.c mod_rewrite.c mod_so.c One final note - the red hat httpd, apr, and perl packages are all installed, but ldd shows that none of those libraries are linked with the running httpd.

  • How to enable hotlink protection without hardcoding my domain in the Apache config file?

    - by Jeff
    Been surfing around for a solution for a couple days now. How do I enable Apache hotlink protection without hardcoding my domain in the config file so I can port the code to my other domains without having to update the config file every time? This is what I have so far: RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://www\.example\.com [NC] RewriteRule \.(gif|ico|jpe|jpeg|jpg|png)$ - [NC,F,L] ... And this is what Apache suggests: SetEnvIf Referer example\.com localreferer <FilesMatch \.(jpg|png|gif)$> Order deny,allow Deny from all Allow from env=localreferer </FilesMatch> ... both of which hardcode the domain in their rules. The closest I came to finding any info that covers this is right here on ServerFault, but the conclusion was that it cannot be done. Based on my research, that appears to be true, but I didn't find any questions or commentary dedicated soley to this question. If anyone's curious, here is the link to the Apache 2 docs that cover this topic. Note that Apache variables (e.g. %{HTTP_REFERER}) can only be used in the RewriteCond text-string and the RewriteRule substitution arguments.

  • How do you enable webcam support in facebook for ubuntu 10.04?

    - by Jonathan
    I think I have finally arrived at an insolvable equation: Chromium v.7 + Ubuntu 10.04 + Sun Java 6 + Webcam + Facebook + Flash 10 = non-functional All of those items listed above are potential points of failure in this situation, and any help narrowing them down would be fantastic. I am simply trying to enable webcame support directly through Facebooks website. Forum searches and the usual googling turn up few posts related to this specific equation. Two of the major suggestions include: 1) Installing the Sun (I refuse to say oracle sob)-provided Java implementation instead of the OpenJDK normally installed in ubuntu. And yes, after installing it, I did update all my default supports to use the sun commands over the openjdk. 2) Somehow enabling Facebook as a permitted site to access my webcam using Flash settings. I have not been able to explore option 2 because I cannot find a way to adjust the Flash settings in chromium 7. Other factors that do not help include the fact that I am pretty sure facebook changes its webcam interface every 10 seconds just to keep troubleshooters and support personnel on their toes. If anyone has a OTP that informs us of the next shift in the app, a leak would be greatly appreciated! Cheers!

  • Why won't sql server express 2008 service restart after I enable TCP/IP Protocol?

    - by John
    Whenever I enable TCP/IP connections on my SQL Server Express 2008 database server running on Windows XP SP3, I cannot restart the service, it simply states "The request failed or did respond in a timely fashion". Any suggestions of what I may have configured incorrectly? [update] Here is the applicable part of the Error Log: MSSQL$SQLEXPRESS Server failed to list on 'any' 3060. Error: 0x2747. To proceed, notify you system administrator. MSSQL$SQLEXPRESS TDSSNIClient initialization failed with error 0x2747, status code 0xa. Reason: Unable to initialize the TCP/IP listener. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. MSSQL$SQLEXPRESS TDSSNIClient initialization failed with error 0x2747, status code 0x1. Reason: Initialization failed with an infrastructure error. Check for previous errors. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. MSSQL$SQLEXPRESS Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log. MSSQL$SQLEXPRESS SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.

  • Coding Practices which enable the compiler/optimizer to make a faster program.

    - by EvilTeach
    Many years ago, C compilers were not particularly smart. As a workaround K&R invented the register keyword, to hint to the compiler, that maybe it would be a good idea to keep this variable in an internal register. They also made the tertiary operator to help generate better code. As time passed, the compilers matured. They became very smart in that their flow analysis allowing them to make better decisions about what values to hold in registers than you could possibly do. The register keyword became unimportant. FORTRAN can be faster than C for some sorts of operations, due to alias issues. In theory with careful coding, one can get around this restriction to enable the optimizer to generate faster code. What coding practices are available that may enable the compiler/optimizer to generate faster code? Identifying the platform and compiler you use, would be appreciated. Why does the technique seem to work? Sample code is encouraged. Here is a related question [Edit] This question is not about the overall process to profile, and optimize. Assume that the program has been written correctly, compiled with full optimization, tested and put into production. There may be constructs in your code that prohibit the optimizer from doing the best job that it can. What can you do to refactor that will remove these prohibitions, and allow the optimizer to generate even faster code? [Edit] Offset related link

  • Enable RFC1323 on a per socket basis in Windows?

    - by Sheado
    Howdy.. Anybody know if it's possible to enable RFC1323 on a per TCP socket basis in windows? I know it can be changed system wide via the registry ( http://www.psc.edu/networking/projects/tcptune/OStune/winxp/winxp_stepbystep.html ) Also, it seems like this is possible *nix via: int on=1; setsockopt(s,IPPROTO_TCP,TCP_RFC1323,&on,sizeof(on)); Is there a Windows equivalent? Thanky much!
