  • How to copy directory from one Linux server to another with a minimum in-between period?

    - by yegor256
    I have a rather big directory on one server (over 4000 files), which I'd like to copy to another server (which contains a previous version of this directory). rsync is the first option, but it will put the destination folder into waiting status for a rather long period of time (more than a minute). I'd like to do it a bit differently: gzip the source folder scp the archive to the destination server gunzip the file there delete the archive at the source and the destination What is the best way to accomplish all this?

  • Are two periods allowed in the local-part of an email address?

    - by Mike B
    A third-party email gateway relay is refusing to process a message for an email address we're sending to. The address is in the format of [email protected] (note the two periods). Is this allowed by RFC guidelines? RFC 2822 seems to object to this in section 3.4.1: The locally interpreted string is either a quoted-string or a dot-atom. If the string can be represented as a dot-atom (that is, it contains no characters other than atext characters or "." surrounded by atext characters), then the dot-atom form SHOULD be used and the quoted-string form SHOULD NOT be used. Comments and folding white space SHOULD NOT be used around the "@" in the addr-spec. Furthermore, in that same section, it references this: addr-spec = local-part "@" domain local-part = dot-atom / quoted-string / obs-local-part I interpret this to mean that the localpart can have content separated by dots but there cannot be two successive dots, and it cannot start or end with a dot. That being said, I'm not familiar with dot-atom syntax so maybe I'm mistaken here. Can someone please confirm and explain?

  • My server is taking too long to respond when I connect to it outside the local network [closed]

    - by Buzu
    I have my local server online most of the time because it is easy for clients to access a url and see how their project is coming along. They can see updates in real time. However, I got a message from one of my clients saying that the server was not responding. I have a hosts file, and in that file I have my server's address pointed to the local ip. This is because some problem with the ftp. Due to this setup, I had not noticed that the server was not accessible from outside the local network. The address is http://imbuzu.dyndns.info SSH works fine, I can connect from my windows machine to the server, but HTTP does not. The server is taking too long to respond. Looking at the logs, I see that the last incoming connection to the server from outside the network is this: 77.242.153.180 - - [04/Dec/2012:12:11:01 -0800] "\xce\x89\x8d\x85b\ro" 400 317 "-" "-" I'm going to restart the server, but I doubt that will have any effect on it. --EDIT-- I restarted the server, and it did not help. Also, I pinged the server and it seems to be resolving correctly.

  • How to copy files without slowing down my app?

    - by Kevin Gebhardt
    I have a bunch of little files in my assets which need to be copied to the SD-card on the first start of my App. The copy code i got from here placed in an IntentService works like a charm. However, when I start to copy many litte files, the whole app gets increddible slow (I'm not really sure why by the way), which is a really bad experience for the user on first start. As I realised other apps running normal in that time, I tried to start a child process for the service, which didn't work, as I can't acess my assets from another process as far as I understood. Has anybody out there an idea how a) to copy the files without blocking my app b) to get through to my assets from a private process (process=":myOtherProcess" in Manifest) or c) solve the problem in a complete different way Edit: To make this clearer: The copying allready takes place in a seperate thread (started automaticaly by IntentService). The problem is not to separate the task of copying but that the copying in a dedicated thread somehow affects the rest of the app (e.g. blocking to many app-specific resources?) but not other apps (so it's not blocking the whole CPU or someting) Edit2: Problem solved, it turns out, there wasn't really a problem. See my answer below.

  • Looking for out-of-place directories in an SVN working copy?

    - by jthg
    An annoyance that I sometimes come across with SVN is the working copy getting corrupted by one of the .svn folders getting moved from its original location. It doesn't happen often if you're careful and use the proper tools for all moves and renames, but it still somehow happens from time to time. First, does anyone know if there's a good way to catch the problem before a commit is even done? Cruise control usually catches the problem, but there are plenty of cases it wouldn't catch. Second, is there a quick and easy way to check for out-of-place .svn folder if I suspect that there is one? I can definitely do it manually by deducing what directory is out of place based on the compiler errors or by diffing the working copy with another clean checkout. But, this seems like a problem that SVN can diagnose in a second by giving me a list of all directories whose parent directory in the working copy doesn't match its parent directory in the repository. There there some way to have SVN give me a list like that? Thanks.

    I am sorry if this is the wrong section but I am starting to get desperate, please someone help me... I need to install the program mrcwa-20080820 (sourceforge.net/projects/mrcwa/) because a summer project that I am involved.

  • WEBrick::HTTPStatus::LengthRequired error when accessing create method in controller

    - by Chris Bisignani
    I have a very simple controller set up: class LibrariesController < ApplicationController ... def create @user.libraries << Library.new(params) @user.save render :json => "success!" end ... end Basically, whenever I try to access the create method of LibrariesController using HTTParty.post I get a WEBrick::HTTPStatus::LengthRequired error on the server.

  • what do i need to do so that mod_wsgi will find libmysqlclient.16.dylib? (osx 10.7 with apache mod_wsgi)

    - by compound eye
    I am trying to run django on osx 10.7 (lion) with apache mod_wsgi and virtualenv. My site works if I use the django testing server: (baseline)otter:hello mathew$ python manage.py runserver but it doesn't work when I run apache.

  • ImageMagick on Mac OSX Snow Leopard. Is there any way to get it to compile and run?

    - by ?????
    It seems that I have more trouble getting standard Unix things to run on Snow Leopard than any other platform--including Windows cygwin For the past couple of days, I've been trying to get ImageMagick to run on Snow Leopard. The most obvious way, Mac Ports, fails: tppllc-Mac-Pro:ImageMagick-sl swirsky$ sudo port install imagemagick ---> Computing dependencies for p5-locale-gettext ---> Configuring p5-locale-gettext Error: Target org.macports.configure returned: configure failure: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_perl_p5-locale-gettext/work/gettext-1.05" && /opt/local/bin/perl Makefile.PL INSTALLDIRS=vendor " returned error 2 Command output: checking for gettext... no checking for gettext in -I/opt/local/include -arch i386 -L/opt/local/lib -lintl...gettext function not found.

So now I'm two steps away from ImageMagick, trying to get a newer libiconv on my machine. I downloaded the latest libiconv, compiled and built it. I put the resulting library in /opt/local/lib, and I still get the same error message: tppllc-Mac-Pro:.libs swirsky$ sudo mv libiconv.2.dylib /opt/local/lib/libiconv.2.dylib tppllc-Mac-Pro:.libs swirsky$ convert dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib Referenced from: /opt/local/lib/libfontconfig.1.dylib Reason: Incompatible library version: libfontconfig.1.dylib requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0 Trace/BPT trap Now here's something interesting. The error message shows it's looking in /opt/local/lib/libiconv.2.dylib. otools -L shows that this does implement 8.0.0: tppllc-Mac-Pro:.libs swirsky$ otool -L /opt/local/lib/libiconv.2.dylib /opt/local/lib/libiconv.2.dylib: /usr/local/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.0) tppllc-Mac-Pro:.libs swirsky$ And, for good measure, I set the DYLD_LIBRARY_PATH to make sure this directory is the one for dynamic libraries. So even though I do have a library that provides 8.0.0, it's being seen as 7.0.0! Any ideas why this would happen? So here's my question: Is it possible to get ImageMagick to run on OSX Snow Leopard? Are there any binary distributions that have static libraries baked in so I don't have to worry about these issue/

  • How can I force a subscriber to be synchronized from a local snapshot?

    - by Brian
    Hello, I have a SQL 2005 server replicating(merge\push) to SQL 2005 and SQL 2000 servers. I have multiple subscribers spread througout the United states. I have set , @snapshot_in_defaultfolder = N'false', @alt_snapshot_folder = N'c:\snapshots\Merge\' (sample location). I take the snapshot from the publisher that is in the same location, 'c:\snapshots\Merge\', and copy it to the subscribers. I wanted to avoid applying the snapshot over the WAN but from the performance I am getting the synchronization is going over the WAN. Does anybody have any ideas how to make sure that I am using the local copy of the snapshot and not the copy at the publisher? Thanks

    I've installed Python 2.6.4 into (a subdirectory in) my home directory on a Linux machine with Python 2.3.4 pre-installed, because I need to run some code that I've decided would require too much work to make it run on 2.3.4. (I'm not on the sudoers list for that machine.) I was hoping I could run ~/Python-2.6.4/python setup.py install (from the PyYAML directory in my home directory, where I untarred the PyYAML sources) and it would be smart enough to install it into my local Python 2.6.4 install. But it's not. (See the P.S.) Is it possible to install PyYAML into my local Python install, so that "import yaml" will work when I invoke that Python? If so, how do I do that? P.S. Here's the output when I ran ~/Python-2.6.4/python setup.py install: running install running build running build_py creating build/lib.linux-ppc64-2.6 creating build/lib.linux-ppc64-2.6/yaml copying lib/yaml/composer.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/nodes.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/dumper.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/resolver.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/events.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/emitter.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/error.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/loader.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/cyaml.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/scanner.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/__init__.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/serializer.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/reader.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/representer.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/constructor.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/tokens.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/parser.py -> build/lib.linux-ppc64-2.6/yaml running build_ext creating build/temp.linux-ppc64-2.6 checking if libyaml is compilable gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/home/dspitzer/Python-2.6.4/Include -I/home/dspitzer/Python-2.6.4 -c build/temp.linux-ppc64-2.6/check_libyaml.c -o build/temp.linux-ppc64-2.6/check_libyaml.o build/temp.linux-ppc64-2.6/check_libyaml.c:2:18: yaml.h: No such file or directory build/temp.linux-ppc64-2.6/check_libyaml.c: In function `main': build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: `yaml_parser_t' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: (Each undeclared identifier is reported only once build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: for each function it appears in.) build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: syntax error before "parser" build/temp.linux-ppc64-2.6/check_libyaml.c:6: error: `yaml_emitter_t' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:8: warning: implicit declaration of function `yaml_parser_initialize' build/temp.linux-ppc64-2.6/check_libyaml.c:8: error: `parser' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:9: warning: implicit declaration of function `yaml_parser_delete' build/temp.linux-ppc64-2.6/check_libyaml.c:11: warning: implicit declaration of function `yaml_emitter_initialize' build/temp.linux-ppc64-2.6/check_libyaml.c:11: error: `emitter' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:12: warning: implicit declaration of function `yaml_emitter_delete' libyaml is not found or a compiler error: forcing --without-libyaml (if libyaml is installed correctly, you may need to specify the option --include-dirs or uncomment and modify the parameter include_dirs in setup.cfg) running install_lib creating /usr/local/lib/python2.6 error: could not create '/usr/local/lib/python2.6': Permission denied

  • Postmaster uses excessive CPU and Disk Writes

    - by wolfcastle
    using PostgreSQL 9.1.2 I'm seeing excessive CPU usage and large amounts of writes to disk from postmaster tasks. This happens even while my application is doing almost nothing (10s of inserts per MINUTE). There are a reasonable number of connections open however. I've been trying to determine what in my application is causing this. I'm pretty newb with postgresql, and haven't gotten anywhere so far. I've turned on some logging options in my config file, and looked at connections in the pg_stat_activity table, but they are all idle. Yet each connection consumes ~ 50% CPU, and is writing ~15M/s to disk (reading nothing). I'm basically using the stock postgresql.conf with very little tweaks. I'd appreciate any advice or pointers on what I can do to track this down. Here is a sample of what top/iotop is showing me: Cpu(s): 18.9%us, 14.4%sy, 0.0%ni, 53.4%id, 11.8%wa, 0.0%hi, 1.5%si, 0.0%st Mem: 32865916k total, 7263720k used, 25602196k free, 575608k buffers Swap: 16777208k total, 0k used, 16777208k free, 4464212k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 17057 postgres 20 0 236m 33m 13m R 45.0 0.1 73:48.78 postmaster 17188 postgres 20 0 219m 15m 11m R 42.3 0.0 61:45.57 postmaster 17963 postgres 20 0 219m 16m 11m R 42.3 0.1 27:15.01 postmaster 17084 postgres 20 0 219m 15m 11m S 41.7 0.0 63:13.64 postmaster 17964 postgres 20 0 219m 17m 12m R 41.7 0.1 27:23.28 postmaster 18688 postgres 20 0 219m 15m 11m R 41.3 0.0 63:46.81 postmaster 17088 postgres 20 0 226m 24m 12m R 41.0 0.1 64:39.63 postmaster 24767 postgres 20 0 219m 17m 12m R 41.0 0.1 24:39.24 postmaster 18660 postgres 20 0 219m 14m 9.9m S 40.7 0.0 60:51.52 postmaster 18664 postgres 20 0 218m 15m 11m S 40.7 0.0 61:39.61 postmaster 17962 postgres 20 0 222m 19m 11m S 40.3 0.1 11:48.79 postmaster 18671 postgres 20 0 219m 14m 9m S 39.4 0.0 60:53.21 postmaster 26168 postgres 20 0 219m 15m 10m S 38.4 0.0 59:04.55 postmaster Total DISK READ: 0.00 B/s | Total DISK WRITE: 195.97 M/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO> COMMAND 17962 be/4 postgres 0.00 B/s 14.83 M/s 0.00 % 0.25 % postgres: aggw aggw [local] idle 17084 be/4 postgres 0.00 B/s 15.53 M/s 0.00 % 0.24 % postgres: aggw aggw [local] idle 17963 be/4 postgres 0.00 B/s 15.00 M/s 0.00 % 0.24 % postgres: aggw aggw [local] idle 17188 be/4 postgres 0.00 B/s 14.80 M/s 0.00 % 0.24 % postgres: aggw aggw [local] idle 17964 be/4 postgres 0.00 B/s 15.50 M/s 0.00 % 0.24 % postgres: aggw aggw [local] idle 18664 be/4 postgres 0.00 B/s 15.13 M/s 0.00 % 0.23 % postgres: aggw aggw [local] idle 17088 be/4 postgres 0.00 B/s 14.71 M/s 0.00 % 0.13 % postgres: aggw aggw [local] idle 18688 be/4 postgres 0.00 B/s 14.72 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle 24767 be/4 postgres 0.00 B/s 14.93 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle 18671 be/4 postgres 0.00 B/s 16.14 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle 17057 be/4 postgres 0.00 B/s 13.58 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle 26168 be/4 postgres 0.00 B/s 15.50 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle 18660 be/4 postgres 0.00 B/s 15.85 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle
