than setting another VLAN and adding to it virtual interfaces Sorry dude, this shows you have no idea what you're talking about. Why in the world do you want this anyways? Are those networks routed to you? Or directly attached? It matters - you'll configure things differently. Anyway assuming that the networks are routed to you, do something like ...

Assigning 512 additional ip addresses to an interface shouldn't be any problem. Here is me adding 1000 additional addresses, ending up on a total of 1001. root@tbox:~# for c in $(seq 1 4); do for d in $(seq 1 250); do ip addr add 10.0.$c.$d/32 dev eth0; done; done root@tbox:~# ip addr show eth0 | grep -E "\binet\b" | wc -l 1001 root@tbox:~#

It is actually possible. You need the debug kernel for that particular distro. On a seperate host. Download the kebug version of that kernel. It will contain a vmlinux file. Open the vmlinux file in gdb. $ gdb /usr/lib/debug/lib/modules/3.14.9-200.fc20.x86_64/vmlinux GNU gdb (GDB) Fedora 7.7.1-13.fc20 Copyright (C) 2014 Free Software Foundation, Inc. ...

Failed to tls handshake with 192.168.2.107 x509: cannot validate certificate for 192.168.2.107 because it doesn't contain any IP SANs SSL needs identification of the peer, otherwise your connection might be against a man-in-the-middle which decrypts + sniffs/modifies the data and then forwards them encrypted again to the real target.

/var/log/syslog is a good place to start. Find the first log messages after the reboot. They will say something about syslog starting and what kernel version you are running. Then scroll up and find the last line, which was logged before the system crashed. Scroll up further to see if you can find any log messages from the kernel itself. Go through other ...

Some of the output is missing, since it scrolled off the screen already, but it's possible to see that the kernel crashed in mount_root(). This means that it had a problem with mounting whatever you passed as the root filesystem. Check to ensure that you have passed the correct parameters to the kernel to boot from whatever media it is supposed to be booting ...

Since it's probably a hardware fault, I'd look at some hardware diagnostics. If you have a hardware RAID controller, I'd find out if you can read its log (if 3Ware, use tw_cli). And, whether you have hardware or software RAID, you can look at the SMART parameters of the disks (if the disks are connected to a RAID controller, you may need special commands ...

https://forums.virtualbox.org/viewtopic.php?f=1&t=45571 Most wireless adapters do not support bridged mode, and even if they do, most wireless APs do not. I suggest you check that bridging is supported in general on your host network interface. Sometimes DHCP requests can get accross, but that doesn't mean the adapter itself can handle answering to ...

installing a monitoring tool If this is only one box, i would not install any monitoring tool, rather rely on scripts. However if you want to go with monitoring tools, i would pick zabbix [monitoring] & ossec [IDS] doing often the updates (how often?) Depends lets take e.g of recent vulnerability on heartbleed, how would you choose to get ...

Change the datadir in my.cnf to the new location. Shut down MySQL (make sure it's fully stopped by tailing the logs!) and just move the contents to the new directory and start MySQL.

I usually do this, just to minimize the downtime.. While MySQL is running, rsync the datadir to a new location First rsync takes a long time, so do another rsync pass or two after that, to minimize the difference. Change the datadir variable in your my.cnf file to the new location Stop MySQL Do another rsync pass to make sure everything is copied to the ...

You defined the default server in 000-default.conf as sub.example.com and it is pointed to the Apache test page. Because it comes first, it overrides the second sub.example.com virtual host you had defined in sub.conf. To fix the problem, edit 000-default.conf and remove ServerName sub.example.com from it.

I see you do not have logs. I would stop puppetmaster on the master server then run it this way: puppet master --verbose --no-daemonize On the node server, stop puppet service and run it verbose with noop: puppet agent --test --noop This should give you some output that will hopefully help troubleshooting. My guess: Certificate issues. It usually is ...

I could not use the host's Cntlm server in the client because I was using the wrong source IP address. If VMware is using NAT (which is how my virtual machine is configured), Cntlm has to listen to the host's IP address in the virtual VMware network, not the host's IP in the corporate network. The following commands were executed on the host. $> ...

Part of me wants to say that Linux shouldn't just crash... Modern operating systems under normal usage patterns should be fairly stable. When I do start seeing server instability, it's almost always a hardware or driver interaction. I would recommend looking very closely at the server, it's conditions and related components (RAM, storage, etc.). If you're ...

The load imposed by a DHCP server with that number of clients is pretty minimal, so any reasonably modern computer would suffice. Bear in mind that you might want to hold on to your DHCP logs for a while, so plan to allocate some disk space to that. However, you should think carefully about redundancy. If your DHCP server fails, it could be pretty ...

The quoted link does not have the complete set of parameters (append line) required for PXE booting Lubuntu 14.04. The kernel panic => the mount cannot be performed correctly because of 1).

According to the docs, busybox 1.12.1 has vi. Anyway, here's your sed regex: sed -i "s/filter\ \=\ \[\ \"a\/loop2\/\",\ \"r\/\.\*\/\"\ \]/filter = [ \"a\/.*\/\" ]/" /etc/lvm/lvm.conf

Either you are using an ancient version of nginx (< 0.7.21) or ngx_http_limit_req_module module is not compiled into your nginx build (which is a bit odd). Run nginx -V 2>&1 | grep --colour=auto limit to check if maybe it's been disabled at build.

Sudo shouldn't care about the hostname of the machine unless it is specified in the /etc/sudoers file. But if it were wrong there you wouldnlt be able to use sudo. If you just want to get rid of the error edit your /etc/hosts and add 127.0.0.1 newhostname.yourdomain newhostname then your machine will be able to resolve that hostname.

Your Apache configuration has a correspondent part in the config files where you can specify how many httpd processes are pre-spawned. This way even on a no-traffic website you can pre-spawn a specific amount of processes. You may need to re-visit that part and lower the values. You can get more information here: ...
