CentOS 5 :: Purpose Of Fs.file-max In /etc/sysctl.conf?
Jul 29, 2010On a production Centos 5.3 system, I want to raise the hard & soft limits of open file handles from 1024 -> 8192 (not a "biggie", I'd think) Right now, "sysctl -a | grep file" shows fs.file-max=463144 (a default, I'd guess) I'm guessing file-max is the maximum number of open file handles on the system, vs the per-user limits seen with "ulimit -Hn" and "ulimit -Sn". Right? If so, I shouldn't think I'd have to touch this on a server with few users.
Also, after doing a lot of reading, I still don't understand the mentions of needing to also add: "session required pam_limits.so" to /etc/pam.d/loginor adding "session required /lib/security/$ISA/pam_limits.so" to /etc/pam.d/system-auth Maybe I've gotten off into the deep weeds in goggling about raising file handle limits.

View 8 Replies View RelatedNetworking :: Sysctl.conf Settings For Best Internet Connection Speeds?
Mar 7, 2011Last week I attempted to get "up to speed" with my Comcast cable connection... Ubuntu 9.10, Dell Vostro 400 desktop, Firefox 3.6.13... Comcast says I should have 12 Mbps connection... if I get 1.0 Mbps, I'm doing good... they just tested everything, and said everything is fine on their end. They use [URL] and connects to a server in Chicago, 60 miles away. That gets fantastic speeds, and it's a durn shame the internet doesn't store all its files there!! I use [URL] for my tests, and it uses a server in Dallas TX.
I go to my girlfriends house, and her AT&T DSL line has d/l speeds of 4.5 Mbps or better!!! She's running XP Pro on a Dell machine. So, started digging on the web and thru the forums, and found this:
[URL]
But, like ALL too many things, it's dated... it's from 2008... I've set my settings to what is there, and disabled ipv6 in Firefox. Hey, now, I'm sometimes up to 1.4 Mbps!! Also found this, but no date...
[URL]
Reading forums, I see that folks have said there is a network connection problem with 9.10... and then I see that others are saying the same thing about 10.04 and 10.10!! I have 10.10 on my laptop and had to fight to get its Atheos card to be recognized. Running some tests [URL] gives me weird results: Download 2.64 Mbps, Upload 4.12 Mbps. NOT what it should be. Similar results from testmy.net.
Dunno exactly what info is needed... Speedguide.net gives me results below, but I've tried changing numbers (says my RWIN is low) and nothing changes:
--------------------------------
TCP options string = 020405b40402080adf1dca100000000001030306
MTU = 1500
MTU is fully optimized for broadband.
[code]....
So, today, find, once again, that I'm d'ling in the range of 90/KB/s (719 Kbps)... disgustingly slow. I go on my HP laptop and run the test, and it says 1.6 Mbps. So, desktop directly connected to router is not even 1 Mbps, and wireless connection is faster? Neither of which is close to what I should be getting...
CentOS 5 Server :: Loading Multiple Virtual Host Conf Files From Httpd.conf?
Jun 1, 2009I've been scanning the apache2 docs for the past few days and have not come up with an answer my following issue:
In my httpd.conf file, at the very end, I have the line
Include conf/vhosts/vhost_*.conf
However, when I run apache checkconfig or try to start apache, it gives me the error:
httpd: Syntax error on line 993 of /etc/httpd/conf/httpd.conf: Could not open configuration file /etc/httpd/conf/vhosts/vhost_1.conf: Permission denied
It appears as if the Include line is correct - in terms of it grabbing the first virtual host conf file. However, I'm confused on the permissions. the /etc/httpd folder is owned by root:root, as are the subfolders. As a test, I chown'd the conf/vhost folder combination and all the vhost files to apache:apache to see if that made a difference, and it appeared to make no difference at all. The log files don't contain anything (assumed because apache isn't starting). If I place the contents of the vhosts in a singular vhosts.conf it works - with the permissions set to root:root. I'd like to avoid having to use one vhosts conf for the configuration I'm trying to achieve - as it would make my life a lot easier.

Apr 11, 2011I am running an application that requires use of my /etc/hosts file. In it, I have my machine name and its LAN ip address. The program creates a service on a specific port, then attempts to connect to it based on the host name. So my hosts file has to be correct.I added the nameservers to resolv.conf and now my application will not run. My guess is that the computer is checking the name servers first, timing out then checking the hosts file.Is there a way I can tell the system to check the hosts file first, then DNS. I thought it should behave that way by default, but it does not appear to.

Mar 1, 2010OS CentOS 5.4 I have a DNS server that is logging all named and dns requests to the chrooted named directory. By default named logs to /var/log/messages but I want to isolate all the dns queries and requests to separate files. I know I can add entries to /etc/syslog.conf to "roll" the logs and logrotate should pick them up but fuzzy as to the syntax. I don't know what "tag" to use in the first fieild. for example
# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none/var/log/messages

Server :: Change Of Apache Httpd.conf Doesn't Work On CentOS/RedHat?
Jun 30, 2010I've been trying to make install apache 2.1.8 and php 5.2.3 and work on them. After updating and installing some dependence files, apache and php could both be installed.
Then I tried to configure them. I added the following content to the end of Apache httpd.conf:
Code:
Then I run /path/to/apachectl start, and saw the message:
Quote:
Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration
Then I remembered that I didn't include the rewrite module while making install apache. So I removed the 2 lines I just added to httpd.conf.
But, after running /path/to/apachectl stop and start again, I could still see:
Code:
When I use firefox to open http://host_ip:8080/, I could see "It works!". But when I open http://host_ip:8080/hello.php (the file is already under htdocs), firefox said
Quote:
Failed to Connect
Why and how to solve it?
I noticed that for some stupid reason, the conf file wasn't updated at all and the 2 erroneous lines were still there.
Ubuntu :: 10.04 Server - Apache Reload SSL Passphrase
Jul 2, 2010I have written a shell script which amongst a heap of other stuff creates virtual hosts, and consequently also reloads apache, however my problem is that unless I include a restart in the shell script, the reload is causing the server to stop, yet restarting everytime a new vhost is created is not really an option since it will disrupt the service for other users. I know this is directly to do with the SSL passphrase as simply restarting gets everything running again with no errors.
I have configured mods-available/ssl.conf so the SSLPassPhraseDialog directive uses the passphrase file instead of bulletin, hence the restart can work fine from within the shell script, but obviously reload and force-reload must be running some sort of background process which involves reloading the SSL certs or something?? so my question is can I over ride this and if so what directive / params do I use? Im on ubuntu lucid 10.04 server and apache v2.2.14.

Server :: Ldap Cannot Carry Slapd.conf Changes Or Did Not Use /etc/openldap/slapd.conf?

it seems that it did not use my slapd.conf so i tried removing my slapd.conf from /etc/openldap and start slapd again and it did start with no errors. and when i do ldapsearch again still uses dc=my-domain,dc=com
I tried searching about this in google and found no answers,
my reference in setting up ldap is the link below. but it seemed that it always uses another configuration not the one i modified

View 2 Replies View RelatedServer :: Phone System Reload Backup System?
Oct 7, 2010At work we have a linux based ip phone system. Now this system was buggy for a bit but we now have it working perfectly. As it is we clone this hard drive and on backup I clone it back. This works but if for whatever I'm not in the office the backup can't go through because apparently no one can read the VERY simple instructions. What i would like to do is burn a cd with a copy of the hard drive (this configuration will change once every 6-12 months at maximum) as well as a VERY minimal linux install.
The goal is they stick the cd in and reboot. The system loads the super minimal linux then it runs a batch file that clones the portion of the CD that has the hard drive onto the system then it asks the nice moron....err....person...to remove the cd and reboot All I need is a a bootable system to a bash script that will run live from cd. I can make the nice bash script that puts to the screen a nice ascii graphic telling the lucky sap it's running and to come back in a little bit to make sure it's done.
Server :: Resolv.conf Was Edited, Server Stopped Serving Websites?
Feb 21, 2010I'll preface this by saying i'm by no means an expert on Linux. A competant beginner at most.We have a dedicated server, the 'resolv.conf' was changed, specifically the domain that was listed (this is the primary domain).I only became aware of this change, when we get into work on Friday and all our sites were down - I attributed this to DNS fault as if I changed my host file (I work on a windows machine) and specifically routed to the domains to the correct IP address, the websites were served fine.I tracked down the resolv.conf change by quizzing a collegue. I then switched the resolv.conf file back to it's original state - luckily a backup was made so I am 100% sure that the current resolv.conf is the correct one.
change was made Friday morning, around 9.30am (UK time). It is now 5.05pm (UK time). The original change was made sometime on Weds afternoon, and the sites stopped serving between Thursday night and Friday morning.Does anyone have any idea how long it should take for the fix to be picked up? Will it be picked up? I just started to think that the change can't be picked up due to some DNS related voodoo.
