I get errors trying to virtual IPv6 Addresses i a lab environment. It works fine up to 2033 (?) adrressses, but when I try to add more i get "Cannot allocate memory" error:
# ifconfig eth0 add 2001:1b70:8282:2021:18:0:20:1
SIOCSIFADDR: Cannot allocate memory
This is on Ubuntu Server 9.10 (64-bit).
I get this error when I run "sudo apt-get install python-software-properties"

I'm trying to install deluge via ssh and my vps has 512mb ram and is only using 11% of it prior to running the code.
While Apache is off, then everything is OK, but if I start apache server after some time I get messages "Unable to fork: Cannot allocate memory" when trying to do some commands with ssh(dir,rm,top and so on).
P.S. There is free RAM when I get that message.
I'm trying to assign like 80 IPv6 addresses on eth0 for virtual webhosting, but after 55 addresses I get the following error:# ip addr add 2a01:9f8:a171:1651::4b:a8af dev eth0 RTNETLINK answers: File exists.What's the problem? I don't understand that error message at all. Is the number of IPv6 addresses per device somehow limited?Ubuntu 10.4.1 server, 64 bit.

I can not use getifaddrs() since it has to be common code between linux, solaris and aix. Solaris and AIX are not having getifaddrs(). Following code is returning only IPv4 addresses.

Does anyone know if there is any way to configure 50K "virtual" IPv6 addresses on loopback device in Linux?
The aim is not to add all 50K IPv6 addresses one by one on the loopback/ETH device which will probably mess up the ip table on the system. In IPv4, I am able to achieve that by specifying the IP address subnet on loopback device (e.g: "ip addr add 10.1.0.0/16 dev lo"). The same command does not seem to work the same way for IPv6. It only adds a single IPv6 address on loopback device and it automatically adds an "unreachable route" entry on the ipv6 route table for that IPv6 network prefix.
The reason I need this is because I am working on an application which tries to simulate 50K IPv6 addresses on a single Linux box. The kernel version I am currently using is RHEL 2.6.9.55.
We have connected two systems with ethernet cables and have configured the two systems with ipv6 addresses. The IP of one system is 2001:0db8:0:f101::1 (let's say X::1) (This system runs OS Fedora 10) and the other is 2001:0db8:0:f101::2. (Let's say X::2) (This system runs OpenSuSE 10.3) We are able to ping from both systems to the other. We are able to ssh into the one with IP X::2 from the one with IP X::1, but not vice versa.
We have disabled iptables on both systems by using the following commands:
/etc/init.d/iptables save
/etc/init.d/iptables stop
on the fedora 10 system and
# iptables -X
# iptables -t nat -F
# iptables -t nat -X
# iptables -t mangle -F
# iptables -t mangle -X
# iptables -P INPUT ACCEPT
# iptables -P FORWARD ACCEPT
# iptables -P OUTPUT ACCEPT
on the openSuse system.
The error we get in trying to ssh from the openSuse system to the fedora system is:
ssh: connect to host 2001:0db8:0:f101::1 port 22: Connection refused
We're trying to write server and client code to send data from one system to the other using SOCK_DGRAM. The code works fine when we run both the client and server on the same system. However, we are not able to send data from one system to another when we use the IPv6 addresses to run the client and server programs.
The error we get is:
sendto(): Operation not permitted
The codes we are using for the server and client programs can be found here in beej's guide here : [URL]. We've only substituted the appropriate addresses in the right places... We've disabled the iptables...
I am trying to use link scope IPv6 addresses to permit two machines to connect using IPv6, but I cannot figure out how to do it without specifying the interface to use on every connection. Here is an example ping:
[root@ppatel-brn1 ~]# ping6 -c 3 fe80::204:75ff:feb6:2994
connect: Invalid argument
[root@ppatel-brn1 ~]# ping6 -c 3 -I eth0 fe80::204:75ff:feb6:2994

I am trying to configure my IPv6 network. My computers are behind a Fedora gateway IPv6-configured, which is working great. But for computers inside my network, it seems I am getting only internal addresses from DHCP. Here is my ifconfig for an internal computer:

I currently have a home server, running Gentoo, with IPv4 connectivity through Qwest.I feel that it is important that this server also be available through IPv6 (I'm aware that, after exhaustion, my end still might not get an address through DHCP).I currently use dyndns.org to provide me with a DNS entry mapping jrvanwhy.homelinux.net to my IPv4 address.I do not have any sort of tunnel set up yet for IPv6 traffic yet. The new domain name does not necessarily have to be the same [URL].I do not wish to spend any money on this.Is there some free service I can register for that would do both the tunneling and the DNS entry? Is there a service that can supply me with an IPv6 DNS entry, if I get a static IPv6 address with another tunnel broker, like Hurricane Electric?

My memory_limit in php.ini is set to 20M. I tried to increase that however it didn't quite work. PHP seems to allocate all possible space and return that message every time i try.

I spend quite a long time searching for an answer however the all things i found suggested increating memory_limit which in this case doesn't work.

View 2 Replies View RelatedI'm running a quite complex model, and it's taking me around a week to complete the run, and one of my colleagues says that he can run it in one-two days. After looking to several forums to know how does it work, I've seen how the memory is used (using the command ps -A --sort -rss -o comm,pme), and the model run just takes 0,3% of the memory. I bought a 4 cores and 8gb of RAM laptop to be able to run the model fast, but I don't know how to allocate the use of the memory to concentrate it in developing that task. Is that possible?

I just switched over to openSUSE about a week ago from Ubuntu and I just purchased an Asus N13 PCI-E wireless network adapter which uses an RALink 2860 chipset. I plugged it in and openSUSE was able to detect it and everything but when I went to go configure it using YaST, it wouldn't be able to scan for networks.
So, I reinstalled my old adapter, downloaded the latest source from RALink and compiled the drivers. When I tried to use insmod on the new .ko that was compiled, I got the "Could not allocate memory" error.
If you need dmsg logs or anything else, I can reinstall the card and get those.
I went to an interview last week and there was this guy who asked a simple question that i have been trying to solve for a couple of days. I tried google but i just cant get the search keywords right. The result were just useless. Well, the question is : "How can we allocate a limited memory to a process before we start its execution" well, the question is related to an X11 system so may be some flags must be set to limit its memory.

View 5 Replies View RelatedMy current plan is to choose a lightweight host OS such as Ubuntu or XP, and then install a virtual machine with Windows 7 as the guest OS. Most importantly, I will use the guest OS almost exclusively. I would like to install all of my software onto the guest OS and then save a "snapshot", as Virtual Box puts it. This is to keep my system free of any unwanted programs I will undoubtedly encounter.
Here are some specific questions I would like answered:
What would be good choices for host operating systems?
What percent of my total RAM (4GB) should I allocate to the virtual machine?
What are the advantages and disadvantages of using different visualization software such as Virtual PC, Virtual Box, and VMware Server?
