Are there any good "GUI"s, webGUIs for managing an "Linux" server? For several use, like the mandriva directory server? thanks

GFS and Small Files
by Hairul Ikmal Mohamad Fuzi 03 May '09

03 May '09

Hi all, We are running CentOS 5.2 64bit as our file server. Currently, we used GFS (with CLVM underneath it) as our filesystem (for our multiple 2TB SAN volume exports) since we plan to add more file servers (serving the same contents) later on. The issue we are facing at the moment is we found out that command such as 'ls' gives a very slow response.(e.g 3-4minutes for the outputs of ls to be printed out, or in certain cases, 20minutes or so) This is completely true especially in directories containing "large number" of small files (e.g 90000+ of 1-4kb files). The thing is, most of system users are generating these small files frequently as part of their workflow. We tried emulating the same scenario (90000+ of small files) on a ext3 partition and it gives almost the same result. I believe most of the CLVM/GFS settings done are using the defaults parameters. Additionally, we would prefer to stick to GFS (or at least ext3) as it is part of CentOS / RHEL distribution rather than changing into other small-files 'friendly' filesystems (such as XFS, ReiserFS). I'm exploring whether is there anyway we can tune the GFS parameters to make the system more responsive? I have read that we can apply 'dir_index' option to ext3 partition to speedup things, but I'm not so sure about GFS. Below are the output from "gfs_tool gettune /export/gfs" : ilimit1 = 100 ilimit1_tries = 3 ilimit1_min = 1 ilimit2 = 500 ilimit2_tries = 10 ilimit2_min = 3 demote_secs = 300 incore_log_blocks = 1024 jindex_refresh_secs = 60 depend_secs = 60 scand_secs = 5 recoverd_secs = 60 logd_secs = 1 quotad_secs = 5 inoded_secs = 15 glock_purge = 0 quota_simul_sync = 64 quota_warn_period = 10 atime_quantum = 3600 quota_quantum = 60 quota_scale = 1.0000 (1, 1) quota_enforce = 1 quota_account = 1 new_files_jdata = 0 new_files_directio = 0 max_atomic_write = 4194304 max_readahead = 262144 lockdump_size = 131072 stall_secs = 600 complain_secs = 10 reclaim_limit = 5000 entries_per_readdir = 32 prefetch_secs = 10 statfs_slots = 64 max_mhc = 10000 greedy_default = 100 greedy_quantum = 25 greedy_max = 250 rgrp_try_threshold = 100 statfs_fast = 0 TIA. .ikmal

apache slow on lan transfers?
by Gordon McLellan 02 May '09

02 May '09

When I download a file from apache on the lan (gigabit lan), I only get 3-4mbps of download speed, opposed to accessing the file via FTP or SMB which results in 500+ mbps of transfer speed. As far as I know, I'm running the stock apache (httpd) that is distributed with centos 5.3, and haven't changed anything in the config file with the exception of setting up various virtual directories. I'm hoping someone can give me pointers on what I need to search for to research this problem. Apache + slow + lan isn't really getting me anywhere. The apache process itself on the server doesn't even register 1% of cpu usage, and iowait is 0% All suggestions are appreciated, Gordon

Rsync/SSH automation problem?
by James Bensley 02 May '09

02 May '09

Hi All, I have a win2k3 server that its backing up to a CentOS 5.3 server. On the Win2k3 machine I plan to have rsync back up nightly to the CentOS server through ssh. The command I am using is as follows: rsync -vrPtz -e ssh myuser@myserver:/remote/backup/folder/ /local/backup/folder/ This all works great for the inital test except its prompts me for a password for "myuser" (as you would except) but how can I embed the password for ssh into the command line? Or can I not? Is the following some how possible: rsync -vrPtz -e ssh myuser@myserver mypassword /remote/backup/folder/ /local/backup/folder/ Or something like that? I can't find anything that says it is possible so its probably isn't but I know that some of you out there have far superior searching skills than I or hopefully, you might already know? Assuming this isn't possible as I've got that gut feeling it won't be, does anyone else have a better idea? BTW; Rsync in running on the windows box through cygwin in case you wondered or hadn't guessed ;) Many thanks, James ;) -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GIT/MU/U dpu s: a--> C++>$ U+> L++> B-> P+> E?> W+++>$ N K W++ O M++>$ V- PS+++ PE++ Y+ PGP t 5 X+ R- tv+ b+> DI D+++ G+ e(+++++) h--(++) r++ z++ ------END GEEK CODE BLOCK------

Web Serving
by Jason Todd Slack-Moehrle 01 May '09

01 May '09

Hi All, My quest is going slowly but surely and I am learning a lot. I use ColdFusion. I installed in on My CentOS 5.3 instance and all was well. I added: DirectoryIndex index.html index.html.var index.php index.cfm index.cfml to httpd.conf and restarted. I put an index.cfm page in /var/www/html and removed the standard index.html and I can see when I hit my IP it works. I then created virtual hosts for a few coldfusion websites in httpd.conf and added the directories to /var/www/html One thing I notice is the owner/group is 501 and games like: drwxr-xr-x 5 501 games 4096 Apr 25 23:57 www_sheldony_com Is this normal? I just did a simply mkdir statement. Did I screw something up? And when I try to hit an index.cfm page Firefox prompts me to download binary data. When I try to hit the CF Administrator I get the same 'binary' data file download. I am running CF on port 80 as I need to. Examples that works: http://67.23.34.37/ Does not work: http://67.23.34.37/cfide/administrator Ideas? -Jason
