Im building a LVS system with 3 server, 1 for Load Balance Server and the others for Real Web server.
LB Server: 192.168.1.111
eal Server1: 192.168.1.112
Real Server2: 192.168.1.113
# echo "1" > /proc/sys/net/ipv4/ip_forward
# ipvsadm -L -n

But I can't connect to http://192.168.1.111.
I'm no expert on DHCP. My problem is that i have a CentOS 5.5 server on which i want to install a DHCP server. I have two NICs where eth0 has access to the internet and where eth1 should act as an DHCP server.
I have installed dhcpd and this is how my dhcpd.conf file looks like.
Code:
ifconfig looks like this
Code:
When i start dhcpd on eth1 i get no error messages but when i connect any devices to eth1 they don't get any IP. I cant find anything in any logs about devices trying to get an IP address. I dont have any firewall rules in iptables.
i compiled and install postfix, and i using relayhost that point to my ISP. but my "DNS server" is on the same server where is installed postfix. and there is running apache with vhosts so i have domain that hosted on same server and in zonefiles of my domain my MX records points to Google Apps, to google's MX servers. But when i try send E-mail via sendmail to mail@mydomainonsameserver.com it not deliver mail to Google Apps totally, if i try to send to another E-mail everything fine it deliver it. so finally i done research this problem in Internet. And find that need to disable deliver mail to localhost(localdelivery)as i think postfix understand that the domain point to the same server where postfix have itself. and try to deliver mail local. but zonefile MX record even the domain on same server can point to another server outside. So i disabled localdelivery in postfix. and problem not fixed

All the howto's I've read so far tell you how to set up certain things, but I don't know what I actually need to set up.Rather than asking the same questions all over again on a forum like this, and generally being a bit of a noob, I wonder if there's a resource somewhere that someone could direct me to in order to know what I need to do to set up a fileserver.

vsftpd ver: vsftpd-2.0.5-12.el5_3.1
I installed vsftpd server in one of my servers using "yum install vsftpd" command. NFS server is running in the other server and mounted as "/data" in this FTP server. root in FTP server has also root authority in NFS server. All the files and sub-folders under "/data" in FTP server have 755 or 766 mode. Even I modified vsftpd setting to allow root login.
When I login as root to FTP server with FileZilla client, I can see all the file list in root home directory and move to /data directory. I can download any file in a local HDD but I can not download any file in /data directory.

View 2 Replies View RelatedI am still quite new to all this but I guess we were all beginners once, this forum seems very helpful.Here is my situation, I will give as much detail as I can.I have a dedicated server which is running CentOS release 5.5.Initially I had Plesk installed, but when I upgraded PHP I damaged the Plesk configuration, and so I installed Webmin instead.
All seems to be fine with this, apart from the DNS configuration / BIND server.I know this because I have one site which uses an external DNS server and this works fine (i.e I can access it from a browser). All the others don't resolve - i.e the ones I set up in Plesk.I've done a bit of investigating to see what is going on, but I'm stabbing in the dark a little.

Running web service and dhcp only on 1pc of a 4pc lan. Optomized minimal slackware 13.1 install (no GUI)on 30g fireball for only one user (myself):
Question is howto work properly in terminal environment: the rule of thumb is not to work on system as root to maintain root's integrity; since i do not have /home for users - what identity do i create to work on files safely? Can you adduser identity without /home as to not work as root? I found 'netgroup' but i am not sure that setting up the id of other machines on lan is what need to do?

I do not see any errors. I also looked in /var/log/messages for any errors and it does not list any.

I have searched and can not find what it going on. Is there some where else errors might be? Could there be a permission issue? The cron job is not being added by the root user.

We are using a hadoop server & we dont want the server memory to overload. So, I have set the ulimit for max memory size and for some time it was working fine but memory was overloading before EOD. I came to know about soft & hard limits and set the hard limit for the maximum memory size in /etc/security/limits.conf file. But, the limits were not shown in ulimit -a command ouput. So, I restarted the server. Then, the limit was shown in the ulimit command output. But, memory is still getting overloaded as you can see the memory used is more than the limit set. Anyone kndly suggest me on this issue.

I'm trying to get nfs server working at boot up and it isn't starting because it says portmapper isn't running. I've read through a bunch of documentation on this and have gotten to the point that if the documentation tells me to Code: Select all$ apt-get install nfs-kernel-server portmap I usually stop there as it is outdated. I cant find a process doc that utilizes rpcbind. So, here is what I've done on my own:
setup /etc/exports with a proper nfs dir and exportfs it
Code: Select all$ apt-get install nfs-common nfs-kernel-server
$ sysv-rc-conf
---│ nfs-kerne$ [ ] [X] [X] [X] [X] [ ] [ ] [ ] │
---│ rpcbind [ ] [X] [X] [X] [X] [ ] [ ] [ ] │
$ service rpcbind start
[Code] ....
The errors however don't seem critical as I'm able to mount the exported directory. OK so it appears to me that nfs server is working. However through a boot, the nfs-kernel-server and the rpcbind services are not starting. The nfs-kernel-server didn't start because rpcbind wasn't running. So I start rpcbind and then nfs-kernel-server and then nfs server works. So what am I missing? Why will rpcbind not start at boot?

(we are both using win 7. he has also disabled firewall both on network and his router)Even more interesting are what I can gather from the command:netstat -anp | grep pptpdIf I run one netstat when I make a successfull connection from my LAN, and one when my friend tries to connect through the internet, the results are identical apart from our IP's. This leads me to believe that there is nothing wrong with neither my network or my friends.

I have changed some settings on my DNS / DHCP config under Debian Lenny, and now when i try to ping some box it only works with long names.
For example:
Ping borsti doesnt work (can not find host) but if i use ping borsti.borsti.iss it works. I have no idea why it doesnt work because i only modified the dnssec-key (created a new key) and nothing else in te config Here is the config i used for bind: (taken from named.conf.options and named.conf.local)

I have created a sub directory on my box on a website for my company. It is a page that has links to my tools I want to use when I do service calls. Links that connect to my servers webmin etc. Of course I don't want them found by webcrawling bots. I have created a .htpasswd file using htpasswd -c /location/to/file/.htpasswd.
This file is located outside the web. Just under the public_html folder. Then I went to the sub directory I want to protect and added a text file named .htaccess. It contains:
/home/sites/www.domain.net/tech/
AuthType Basic
AuthName "Some long name"
AuthUserFile /home/sites/www.domain.net/.htpasswd
Require valid-user
ErrorDocument errornumber /home/sites/errorpages/403.html
I also opened the httpd.conf and changed AllowedOverride to All
The error document doesn't work either.

If I move <directory> in the main httpd.conf (ie , outside virtual host section), then again it works fine.
