View 3 RepliesI have a rented vserver running at Strato [URL]. It came preinstalled with Debian 7. I upgraded it to Debian 8, what seemed to run fine, all services running. The problems came up when I tried to reboot the server to test the init system. It just does not come up, I cannot ping it, nothing. I can boot into the rescue system, mount the system partitions and chroot in to the filesystem. In this state I also can run my services, including apache2 and mysql. In the syslog I find nothing about the reboot. Now I need to reboot ino the normal system. I already tried to resume to sysvinit without success.

In the virtual machine, I need update the kernel. I used "yum update kernel" and this is downloaded correctly and the menu.lst file is updated too, but the kernel not ran. I ran "grub-install /dev/sda" or "grub-install /dev/xvda" and received a error return. I read the device.map file and i ran "grub-install /dev/sde" and received a error return too.
The errors:
[root@vm01 ~]# grub-install /dev/sda
/dev/sda: Not found or not a block device.
[root@vm01 ~]# grub-install /dev/sde
/dev/sda1 does not have any corresponding BIOS drive.
[root@vm01 ~]# grub-install /dev/xvda
/dev/xvda: Not found or not a block device.
I'm using Debian 5 with Exim 4 on my VPS. My purpose is to make mailboxes for each virtual host on my server. What do I have: 1. Exim is set correctly - receiving mail from [URL]... is successfull. 2. Mail for [URL]... is delivered, and the mail for [URL]... too. But [URL]... is the site written to /etc/hosts (it's localhost), and [URL]... is virtual host. But mail from both boxes writes to /var/mail/mail. Now what do I need: 1. Make mail for [URL]... store in [URL].... and mail for [URL].. store in www/Maildir. 2. Make mailboxes like [URL].... to receive mail by Thunderbird. 3. Set passwords for [URL]... and [URL]... (I don't want to enter my system user/root passwords).

View 2 Replies View Relatedwhat is happening on my Centos virtual server (ps I'm having a great time re-learning Linux after a large gap and usually try and find out myself but this has me confused) First thing I did was install Tomcat and try and change the port to 80 using iptables -nat and it complained a kernel module was missing. Instead setup Apache to redirect requests so that's now working I then tried to install CSF firewall and the validation perl script returned fatal errors so I assumed OK my virtual server Kernel is restricted and used denyhosts instead which is working great
Here's the confusion.. I later retried the csftest script and it now works including all the iptables and nat stuff that fataled before. I've not rebooted or changed anything except run denyhosts and the postgres daemon + ended a few daemons that I didn't need (eg pickup,tlsmgr,courier,postfix,qmgr,saslauthd) Running lsmod returns nothing and /proc/modules is zero bytes so I'm not able to tell what is loaded? I'm tempted to try and get Tomcat redirecting via iptables and see what happens but if it works I don't like that something seems to have changed.. before I ran it direct as root now I'm SU into root from another login
I've installed Nginx-full on a debian jessie server and want to install Wordpress, but for some reason Nginx-full isn't being seen as providing the httpd virtual package, so wordpress insists on installing apache.
According to everything I can find, nginx-full provides the httpd virtual package and this shouldn't happen. Is this a bug?
How to best manage both http and https pages on the same apache-server without conflicts. For example, if i have both 000-default.conf and 000-default-ssl.conf pointing to mydomain.com, and don't want users who visit mydomain.com without specifically type the https-prefix to be redirected to the https-page - how to handle users using browserplugins such as https-everywhere etc?
Another option would be to create a subdomain ssl.mudomain.com and have users who want to reach the ssl site to have to type ssl. I have tested several things with https everywhere enabled in my own browser, and it seems really hard to make this working the way i want, in one way or another i always end up getting redirected to the ssl-site automatically.
The reason i need this to work is because i run one site that i don't care much about SSL, that is the "official" part of that site, and i also host some things for friends and family on the SSL-part. This would not have been a problem if it wasn't that i use self-signed certificates for my ssl-site and the major user become afraid when a certificate-warning pops up in their browser and therefor leave the site.

I installed a new squeeze serverXen Hypervisor runs the server as Dom0 anda virtual Windows XP.The server runs samba, postfix, dovecot, squid, cups and hylafax with a Frritz ISDN card (module fcpci.ko).The used memory of Dom0 rises slowly (about 5MB /h) until the system crashes.As a workaround i installed a reboot every 24 hours.htop shows normal behavior.The system is already in production, so i can't stop services to track this bug.I need some hints how to debug the running system to find out, where the memory gets lots.

apache virtual host to limit the concurrent connections of virtual hosts? Taking into account the host of each virtual user's home directory can also have more than one subdirectory, which should be restricted to a subdirectory. Is beyond the control of the operation of these sites in a subdirectory. Best local restrictions or limitations to the overall situation.
View 1 Replies View RelatedI'm having an issue with setting up the virtual hosts on my web server. I have 2 virtual hosts (example1.com, example2.com). example1.com works but example2.com is sent to the index file of example1.com. I did some searching on google and it seems the problem might be with my /etc/hosts file.
First virtual host that the second is also directed to...in sites-available/sites-enabled (note port 80 is blocked by my isp so I use 8080)
Code:
Second virtual host file
Code:
And my hosts file
Code:
# The following lines are desirable for IPv6 capable hosts
Also I'm using a dyndns.org...would that make a difference?
Is there anyway for one Virtual Server to access the main host, or another Virtual Server? Or would they be totally 100% independent?

View 8 Replies View RelatedIn the past I found some great help on this forum, so here goes. Bare with me because it's a long story. I'll try to be as complete as possible. I've installed and configured OpenLdap on a virtual machine with ip 192.168.39.134. I've added 2 users via LAM. In the ou WikiUsers and the domain is wiki.local.
I've then created another host with ip 192.168.39.133 with mediawiki installed on it. Then I added the extension LDAPAuthenthication. In the LdapAuthentication file I added this code (only the last paragraph is mine, I added the others to show it's location in the script):
Quote:
$path = array( $IP, "$IP/includes", "$IP/languages" );
set_include_path( implode( PATH_SEPARATOR, $path ) . PATH_SEPARATOR . get_include_path() );
[code]...
I know I'm close because I can't register any new users or accounts on the mediawiki site. Although I could before I added the LDAP service. This is indeed all just to test and get to know how LDAP works. That's why it's all virtual in VMWare. I did not really configure anything on the LDAP, i just installed it and chose a domain (wiki.local).
I've got a working Virtual Postfix server running with mysql doing user authentication. I have a support email address set as support@hostname.com, which has 5 aliases associated; user1, user2, user3, user4, and user5. When an email is sent to support@hostname.com, all 5 users receive the email, just as planned. What I'm looking to do is when an email is sent to support@hostname.com to have it rotate through the members of the alias group. That way all members of the group get support emails evenly and not everybody all at once. Is this possible?

View 2 Replies View RelatedI have a set of vm's with stable, testing, and sid to keep track of how things are going. When I did an apt-get dist-upgrade with squeeze last week, things seemed to OK (350 package updates) until the end. It didn't seem to like and / or was confused by a kernel dependency.
I am not too concerned yet. Because these are in vm's, I do a snapshot before any significant change. I can futz around with impunity because I have that backup.
I re-booted, and tried the apt-get dist-upgrade again with same results. I think I also tried apt-get -f install.
So I reverted to the snapshot, and will simply try again in the future. I recall that with lenny as testing, the font-desktop was really screwed up for about a period of 6 weeks.
However, just in case someone else runs into this:
1) a re-boot worked, but the failure of apt-get made me nervous enough to revert.
2) waiting for corrections has seemed to work in the past (with a single exception with a 4-disk SCSI software RAID10 update that failed to re-boot lenny successfully after what seemed to be a minor update -- that was on a real system, not a vm. I haven't gotten back to look at that.)
My company support a client with an old Redhead server " Linux version 2.6.9-5.ELsmp [URL] (gcc version 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)) #1 SMP Wed Jan 5 19:30:39 EST 2005" My IT department wants to move this old server to a VMware machine and I'm trying to check if this project can fly. Me my self never worked on an old Linux server there for my first question is can I upgrade the kernel with the command yum -y install kernel..... and when I'm done I'm still going to have the old kernel just in case?

I'm just trying to know if is there is a way to run the first version of linux in a virtual machine. Since I am very new to this, my aim is to learn something basic on how the first version of linux kernel was built and worked.

How can i get a RAID virtual image disk?
What i need is to mount several directories from any other partiton (or file system) as a new merge file system that can grow or decrease depending on the free space. As if it was a dinamic RAID,so i can work with huge files distributed over the partitions mounted.
Ejemp: /mnt/sda1/dir_raid1 + /home/dir_raid2 + /mnt/sda3/dir_raid3 ---> /mnt/RAID/
mhddfs and unionfs <---- are not the solution im searching (cant use huge files)

I have a debian squeeze box with dual NICs that I'm trying to configure with two virtual hosts. I'd like to have one of these machines act as a router for the 2nd NIC so I can plug in a switch and have a separate subnet.
Something like:
- Openwrt router 192.168.1.1 (firewall/vpn/stats for 192.168.1.0/24 domain)
- KVM machine with 2 NICs (192.168.1.2)
- Virtual machine #1 has a fixed IP of 192.168.1.3 (virtual nic)
- Virtual machine #2 has a fixed IP of 192.168.1.4 (virtual nic) but also controls the 2nd nic and routes 192.168.80.0/24
I'd like to use the 192.168.80.0/24 network for testing equipment without poisoning my existing network.
