I have installed Debian Lenny 5 and am trying to access the server via SSH port 22 but it keeps telling me : Connection refused .Any ideas how to enable this SSH on Debian server for connections ???
View 6 RepliesI run a webserver Apache2, php5, and MySQL. They are all set up correctly and I can access my website at [URL] I have, also installed, noip2 to update my IP address to no-ip.com for my domain name. Here's the problem: I can access my website through that domain name on other computers, both on internet and on the same network. But I cannot access it from my own computer (using the domain name instead of localhost). I need to be able to access the domain name on my computer because some pages on my website have been defined as the address to my domain name and not localhost. I cannot change this to localhost because if I do then people outside cannot work the webpages correctly. I had the same troubles on Windows before and I simply enabled loopback connections by typing in my private IP address along with the domain name into the Windows hosts file. I use version 10.04.

View 1 Replies View RelatedI have a server that I can only access via SSH (it's located far away) and I would like to secure it by blocking all ports except the ones that I need (which are HTTP and SSH). I still want to be able to make outgoing connections to enable software updates and other things.This is my iptables -L -n :
Code:
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:1:21
DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:23:79
DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:81:65535
code....
In my opinion, this should block all incoming packets except the ones on port 80 and 22, but allow responses to outgoing connections. But a wget http://google.com does not work, it can't establish the connection.
Maybe this is not the best style for iptables rules, but I want to be absolutely sure to not accidently lock myself out from SSH, so I chose not to configure a "block-everything rule".
Does this configuration not enable incoming packets from connections initiated from inside?
Is there a way to enable a web interface to access openssh-server on my vps incase i'm on a network that does not permit outbound port tcp 22 or any other port of my choosing?

View 3 Replies View RelatedMy Apache web server (respectively a child process) is crashing several times a day. I wanted to find the exact reason and activated the core dumps but even though the crashing-issues continue, the core dumps were never created. I have found several howto's which basically point to the same steps:
- set "ulimit -c unlimited"
- add "CoreDumpDirectory" directive into apache2.conf (Debian's httpd.conf)
Another info I've found is that /proc/sys/fs/suid_dumpable shouldn't be 0 - so on one howto it said to echo 2 into it, on another one to echo 1 to /proc/sys/fs/suid_dumpable - didn't work with neither of them.
Does anyone know how to permanently enable X connections from all machines on my local network. I keep having to enter 'xhost +' to allow X connections.

One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine.

Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?
View 3 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 5 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)
bash 13839 root 2u IPv4 3118986 TCP shana:34323->161.53.178.240:distinct
[code]....
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.
Suddenly, nothing can connect.

Is it possible to do limit the SSH connections using IPTABLES, like per day minimum 10 times only ssh connections can allow like that, or any other way to limit the SSH connections.
View 1 Replies View RelatedOk so, buddy of mine has his ssh server setup and upon checking his logs he sees a ton of failed attempts.

I am trying to add an OpenVPN connection from the Network Connections GUI. The problem is everything is greyed out when I am logged on as a user. When I log in the GUI as root I can create the OpenVPN connection no problems. The problem with that is the option to use my newly created VPN connect does not appear when I log back into my user. I have tried adding my user into the sudoers file to no avail.
How can I give my user privileges to add OpenVPN connections?
I have ssh installed and running on my laptop(Debian Sequeeze). I can run "ssh localhost" without any problem. But for some reason I cannot connect to it from other computers.

View 5 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".
