My new box has gotten laggy as all get out.I did a netstat just for the heck of it and:
Code:
0 0 localhost.localdoma:ipp localhost.localdo:47567 TIME_WAIT -
tcp 0 0 localhost.localdoma:ipp localhost.localdo:47557 TIME_WAIT
[code]...
When I typed netstat -lna, the output:
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:580 0.0.0.0:* LISTEN
...
...
Active UNIX domain sockets (servers and established)
Proto RefCnt Flags Type State I-Node
unix 2 [ ACC ] STREAM LISTENING 23581
...
...
Can anyone explain to me:
1. What is "Active Internet connections" & "Active UNIX domain sockets"?
2. What is unix Proto?
3. Difference between LISTEN and LISTENING state.

View 6 Replies View RelatedIs it fair to say that connLimit and hashlimit are very similiar on Linux i.e. while hashlimit caters to limits for groups of ports, they both set the connection rate limit per host? How in IPTables, do I configure a policy that limits connections on a port that encapsulates the total sum of all connections from all hosts? i.e. I do not want to allow more than 6000conn/minute for port range that is the sum of all connecting hosts?

View 1 Replies View RelatedBasically it looks like someone is flooding the UDP port for our server, which is running a game (Halo PC) through wine on Linux.I've tried "netstat -aun" but only get 0.0.0.0.'s as the IP address. there's anything I can install to log connections or any command I can run. Specifically they need to be UDP on port 2302 and port 2304- but since these Halo servers are the only thing running on this server, logging all connections would equally suffice.
View 1 Replies View RelatedFor some time now I've been noticing the network activity light for my linux box blinking like mad on my router. After a little looking around for ways to see what connections my box has established, I found the following using lsof -i
Code:
bash 13839 root 1u IPv4 3118972 TCP shana:49148->Oslo.NO.EU.undernet.org:ircd (SYN_SENT)

I know I'm not using IRC, and I have my sshd locked down fairly tight, requiring a key to log in, so obviously, it looks like there's something or somebody in Croatia (the origin of that IP address) connecting my system to undernet.org for some nefarious purpose. Looking at my processes, ID 13839 shows up as
Code:
13839 ? S 0:00 bash
Just 'bash', not '-bash' as
Code:
13426 pts/0 S 0:00 -bash
my session appears. Previously, this odd bash process was ID 2704, which seemed to imply that it had launched fairly soon after my system booted up which really makes me wonder. Oh, and yes, I did kill that 2704 process, and it returned as this 13839. 2704 also had those same IRC connections present in lsof.
I have a little file server, which also acts as a printer server and it has a web server implementation for Mapserver too.

View 2 Replies View RelatedI am developing a node application and there is an option to set the process title (process name). This only sets it in some tools (like ps and top), but not in htop or netstat.
I found this article that explained how most applications do it, but it doesn't change in netstat.
That lead me to wonder where those programs are getting the process name. Would they be getting it from /proc/##/cmdline? (## being the PID of the process)
I figure messing with things in /proc is a bad idea (and probably not possible), so if this is where those programs are getting it, is there a way to change it?
I need to know what this means and what to do to fix this. code...
View 9 Replies View RelatedI have a question, regarding the use of two internet connection on the same server. So, the thing is like this: The server will have 3 network adapters: connected to a DSL modem (on this adapter I have one of the internet connections, a PPPoE connection. It's only purpose is to share the internet connection to all LAN users using SNAT.
eth1 ----> the other internet connection, a much more expensive one actually, used for hosting a website, a domain name server, and a qmail server. eth2 ----> LAN connection So what I want is to make eth1 the "default gateway" (for outgoing mail, DNS requests, etc) and, as I said, use the ppp0 connection on eth0 only for internet sharing in LAN.
My question is (since I'l configure this server in about one week), does anybody have any suggestions regarding how could I accomplish this? I mean, I'm affraid that ppp0 will also try to use the default gateway from the other internet connection and vice-versa. Now, I know I can use the ip route/ip rule commands, but for many reasons I'd like to keep it simple and not use them.
I'm curious how I can use a Windows client with two separate accounts to connect, at the same time, to a SMB server hosting two shares. (Provided permissions and accounts are all in order)
Scenario:User1 is always logged onto a Windows client mapped to a Public share on a Linux SMB server.I need a way to keep User1 connected to the Public share and then when needed, allow User1 to provide User2's credentials to connect to a Restricted share.The only way I've been able to do this is to disconnect from the Public Share then reconnect to the Restricted share using User2's credentials. (This is the issue because I need to keep User1 connected to the Public share).Is this a limitation of SMB? Or am I missing a configuration? Please point me in the right direction
I'm having problems getting openssh server to accept connections in Ubuntu 10.04.Here's what I've done (twice): Installed Ubuntu 10.04 on USB drive with pendrive installer. This creates a default user "ubuntu" and you don't get the chance to choose a password for it. Started a keyring for network access and selected password. Works.Enabled VNC and selected password. Works fine with VNC client on local network. Logs in as "ubuntu" user and asks for the VNC password, then connects. Note: the client doesn't know the "ubuntu" user password, and neither do I! However, it works.Installed openssh client and server from Ubuntu s/w center.
$ ssh localhost OR $ ssh ubuntu@localhost try to connect, but asks for password, which I don't know (see step one, above) so, then I created a new user, with known password, logged in as new user in Ubuntu, works.however, $ ssh newuser@localhost still fails, even when correct password for <newuser> is supplied. Rejects the password three times, then gets the usual error about keys.I also tried connecting with an SSH terminal app from my iPad, again using <newuser>. It gets essentially the same error, "failure to authenticate".
All this is still on my own LAN, haven't gotten to going outside the router yet.What I want to do in the end is use VNC over SSH from a client on my iPad to talk securely to Ubuntu while I'm traveling.
I ran an update on ubuntu server today, and after a long install process, it spat out an error, telling me to run "sudo dpkg --configure -a".

View 8 Replies View RelatedI have a server running on Ubuntu and I am having 2 problems: SSH-KEYGEN related-> I have several computers and I ssh into each, so I initially set up keyless connection via the following commands (more or less)
ssh-keygen -t rsa scp id_rsa.pub user@host:
#remote computer
touch .ssh/authorized_keys
chmod 600 .ssh/authorized_keys
cat id_rsa.pub >>.ssh/authorized_keys
everything works fine at first when, for example, connecting computer A to computer B. And it still works when connecting computer B to computer A. But when I introduce computer C, all of a sudden computer B gets fussy and no longer does keyless connections. Or if I have multiple users on computer A, lets call them A1-A9, then only A1 accepts keyless connections. My question is this: what is the rational between allowing keyless connection for some, but not all computers and/or users?
