The three lines in /etc/services for nfs (2049) has UDP, TCP and one I haven't seen before sctp. what is sctp and does iptables block it?
View 3 Replies View RelatedIf I open a raw SCTP socket, am I able to bind to a specific port? (I only want to see SCTP packets from a particular IP address AND port.) Or, any raw SCTP socket, regardless of port binding , will get all SCTP packets received by the OS from that IP address? The port doesn't matter and is ignored.

When I try to close the socket with the socket descriptor, sometimes it is not closed without errno.
Like in the subject. Does anyone knows how to do it without restart
View 1 Replies View RelatedOn 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.
My sysctl.conf in /etc isn't loaded at boot, it does however get parsed with the command # sysctl -p I believe this problem started when I got the 3.0.0 kernel just a few days ago. Does everyone has this problem? Then it's probably a bug.
My system:
Debian Testing (Wheezy)
3.0.0-1-amd64
up2date
I made some change to my sysctl.conf file and it they doesn't seem to load at boot? Each time I boot I need to send a sudo sysctl -p command to load the new parameter!

Add the following line to /etc/sysctl.conf
vm.swappiness=10
How can I find the size of units in sysctl.conf e.g whatis the size of the shmmax variable i.e. is it byte kb , Mb etc....???

View 8 Replies View RelatedLast 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...
Does anybody have experience with linux tuning. I`m realy interesting about sysctl.conf tuning settings for batch(3d rendering, phisycs simulations, etc.) servers. Does anybody has an experience with linux tuning - I mean memory and CPU settings for heavy loaded systems. What kind of settings You have in Your clusters ? I`m working with Red Hat Enterprise 5 x86_64.

i installed firefox 4 and removed the old 3.X version. did a general update that my computer showed me was available then i noticed the first problem. firefox 4 would not launch when i clicked it, it would only launch when i clicked the gnome 3 applications button and then clicked and dragged the firefox logo to the desktop, then it opened. the second problem i am now having which at the moment is more bothersome is that after i closed the lid to my laptop and opened it up again after a while and logged back in and noticed that the ENTIRE gnome 3 environment was gone. no panel no menu nothing just the desktop and a few desktop icons. i tried the command "yum install gnome-shell" but it just sed that gnome 2.31.5-7 .fc14.i686 was already installed so it wasnt gonna do anything, then i tried the "gnome-shell --replace" command and it just said

I've installed openSuse 11.4 server-mode (text only) on my desktop, and I'm trying to configure IceWM so i'll eventually have it set up so it always boots into text only mode, but I could be able to quickly start icewm via the command line.using Yast, I installed the Xorg server, and icewm.when I type X, the screen goes black and it just doesn't seem to do anythingI found if I hit ctrl+alt+f1 it kinda puts me back into text only mode, but I can't put in commands anymore. The last thing it says on the screen is:
Failed to load module "fglrx" (module does not exist, 0)
I've goggled that error message and the discussions that popped up around it made no sense to me at all. I've never configured X from scratch before, can someone point me towards a tutorial or something?
