i'm having a problem with remote command in ssh.

The following commands run just fine:

ssh remote_server ls /path/to/folder/

(list all files of the folder - OK)

ssh remote_server ls /path/to/folder/file_000*

(wildcard match one file of the folder - OK)

The following command hangs:

ssh remote_server ls /path/to/folder/file*

(wildcard matchs some of the files - HANGS)

ssh remote_server ls /path/to/folder/*

(wildcard matchs all the files - HANGS)

The remote folder does not have a unreasonable amount of files: about 50, 40 of them would match 'file*' regex.

Running ssh with -vvv flag gives me the following output

[...]

in which point, hangs.

Any ideas?

Source is Oracle Linux 6.9 Destiny is Oracle Linux 7.5

I'm using Oracle RAC in RH6, and when i try to use the 'oraenv' utility to set the variables with the user oracle, i get an error:

[oracle@vhor12 ~]$ . oraenv
/bin/.: Permission denied.

Using it in the same way with the root user works normally. Also, without the "dot space" preceding 'oraenv', also works.

Unfortunally, using without the 'dot space' will not have the same effect.

Anyone can give a clue?

Tks in advance.

I have a git over http using apache+webdav, autenticating on a ldap directory.

It is working ok for most users, but since last friday (FUN FUN FUN!!! just kidding), when one particular client tries to push to the server, his client gets in a loop, and none of the other clients can push, although they can pull.

To solve this, a have to stop apache, remove the DavLockDB file, create it again and start apache again.

This will work until this client tries to push again.

This is what i already have tried:

• update the client software (tortoiseGIT)
• check the client clock
• check client user permissions (client can authenticate against ldap and pull code from git)
• check client network permissions (client is able to access the apache directory)

Other infos: client can't push in any existing project, but can push in a newly created test project.

If anyone needs more info to help me with this, its just ask =D

I have a root directory 'data_0'. Under this directory are about 15,000 directories ('a', 'b', 'c', ... 'aa', 'ab' ...). Under each of theses directories there are thousands of very small files (4~10kB), something between 1,000 and 2,000 files each.

All this leads to 30 million files. I need to move these from 'data_0' to a 'data_1' folder, but without the "level 2" folders (a, b, c etc), so:

/data_0/a/1.txt --> /data_1/a_1.txt
/data_0/a/2.txt --> /data_1/a_2.txt
...
/data_0/ccc/989.txt --> /data_1/ccc_989.txt
...

How far can I go with this? Performance is unimportant here. Is there a logical limit or just a performance limit?

i have a Windows Server 2008 R2 (64bit) running a 64bit installation of Firebird 2.1.4.18393_0 in a 4GB phisical server.

After a while, the task manager show that all memory is used, but the sum of the memory of all process does not stack to the half of the memory. Unfortunally, it's start swapping.

Using RAMMAP, i can see that my entire database file is mapped into the memory. This only occours in windows server 2008 r2 and windows 7 64 bit. i can use firebird 32 or 64bit installations, doesn't matter.

How can i prevent this? Why this only occours in w2k8r2 and w7?

tks in advance

** UPDATE

Aparently, this occours by the use of all memory by the file system cache. The microsoft documentations explain that this WAS a issue in windows xp, 2k3, vista and 2k8, but it was solved in 7 and 2k8r2. also adds that this issue is more common in 64bit hosts. (http://support.microsoft.com/kb/976618)

there are some tools (DynCache, setcache and the Get/SetSystemFileCacheSize system calls from windows API) that allows me to fix a upper limit to the memory usage by the fscache, but the documentation argues that i should not do this in w2k8r2 because it will severely impact on the overall system performance. anyway, i tried, the performance remained the same shit and the use of the page file remained, although there is now more the 1gb of free memory.

i have an application that make use of nginx and the Nginx Http Push Module (http://pushmodule.slact.net/). Today i use it on linux, but i want to use it on windows. Is there a way or a a pre-compiled package?
