I just downloaded the DenyHosts2.6python2.5.rpm for deny.hosts from sourceforge and would like to set it up. I normally use fish://, smb:// and ftp:// on the boxes on my lan. I already have files called hosts.allow and hosts.deny in the /etc folder. Will the rpm configure hosts.deny when first run?
View 1 RepliesI'm having troubles trying to understand this problem:my homeserver until yesterday had a public IP, staying on network, with sshd running and all was fine;this evening I changed the IP, giving it a local lan address, and what happened if I tried to connect to it by ssh?I got an error about "Connection closed by remote host". Google helped me finding that was regarded to hosts.deny file, that was actually containing a lineALL:ALLthat I commented, and all was fine.My question is: why the hosts.deny (that has never changed) was observed only with the local IP?I tried to switch back to the public IP and leaving ALL:ALL, and it did connect without any problem

My question is the following blog says to remove an IP from /etc/hosts.deny which denyhost has blocked
[URL] you need to have a directory /usr/share/denyhosts/data I do not find any such directory
Also when I tried to check tcp wrapper configuration as given here
[URL]
tcpdchk -v Cannot find your inetd.conf or tlid.conf file. Please specify its location.
what does the above output mean? How do I make sure denyhosts is doing its job?

Probably an easy (which means stoopid) question...I am trying to reroute a website using my hosts file so that it matches my servers certificate file for testing without effect dns and the live site.When I went to edit my /etc/hosts file it is non-existent. I have, I am assuming in it's place, hosts.allow and hosts.deny. Can anyone explain why I do not have a hosts file?

I have read the man files on hosts (deny/allow) and think I understand how they are supposed to work but reality has proven me wrong.
My simple test case was to add "ALL: ALL " to the end of hosts.deny which I though should make the Internet not work. I can still look up hosts fine so apparently I don't understand these files or Ubuntu is ignoring them.
This is my hosts.deny file

I have setup Denyhosts to run on my server, and have been using it succesfully for the last few weeks, to allow me to ssh into my server from my home dev machine.
This morning, I accidentally typed my password incorrectly three times - and ended up being locked out of the system (tghat was ok, because that was what was supposed to happen). I logged into the server via another way and took the following actions (in the order given)
/etc/init.d/ssh stop
/etc/init.d/denyhosts stop
removed my IP address from /etc/hosts.deny
/etc/init.d/ssh start

I'm trying to use ssh-keyscan to get some known_host file population going on, but I have a ton of hosts I want to scan, all with multiple aliases in /etc/hosts. Is there a way to use my current /etc/hosts file to do an ssh-keyscan instead of making a special list of hosts that (from what I've read) ssh-keyscan needs?

i was hoping that someone in here could possibly help me out with my iptables rule set. First here is what i would like iptables to do, i want iptables to deny all packets or traffic from the outside coming in and for output allow the things i need like web and irc etc... Also, i would like iptables to deny access to all services like sendmail and ssh except i would like localhost to have access to everything. What i mean by localhost is that when i run my iptables script it loads fine except when i try ssh from localhost i get this output:ssh -l user localhostssh_exchange_identification: Connection closed by remote hostI know what most of you are thinking, why do i need to ssh into localhost from localhost just open another terminal, well i am getting myself familiar with iptables i want all services logged and blocked but not from localhost. I cant seem to figure out this problem and i have tried several different things. Here is my iptables script, I am hoping that someone out there can tell me what i am doing wrong...
#!/bin/bash
iptables -v -F;
iptables -v -A INPUT -i lo -j ACCEPT;

View 6 Replies View RelatedI have an Asterisk on an externally hosted vServer with Lenny. In order to further protect the SSH access I intended to change the Port number 22 to something like 55555. For this I changed the /etc/ssh/sshd_config file and restarted ssh. This caused unfortunately the following problems:
(1) The first login works but DenyHost writes now the IP in its list so that the second login with the same IP is blocked.
(2) With RESET_ON_SUCCESS = yes several logins were possible with the same IP, but later it also was blocked for some still unknown reasons.
(3) Files can be uploaded for being edited, but they can't always be saved. When they can't be saved the next login with this IP is blocked. It thus looks like the blocking can occur while being connected. When the files can't be saved it is however still possible to copy files from the computer to the vServer.
I add below the entries in the auth.log from a logout and a login. It shows further how suddenly the attempts to save files were blocked. After this session the IP used for it was blocked. I don't know where the message "Unable to open env file: /etc/default/locale" comes from. If I remember right I had these messages already before. I don't know how much that is really important.

If I allow, my server's IP is:
11.11.11.11
If I allow 11.11.11.11, and block 22.22.22.22
22.22.22.22 can't access the server
But if I allow 11.11.11.0/24, and block 22.22.22.22
22.22.22.22 can still access the server!!
Does anyone know why that is?

I made a Desktop User account. When I went on that account, it allowed me to execute sudo as if I was an administrator. I don't know what might be causing this. I do have ufw set up and blocking incoming connections. Do you guys know what might be at the root of this?Also, when I used sudo from the user account (which I shouldn't have been able to do), I provided the password for my admin account.

where realmailserver1.yourdomain.com. and realmailserver2.yourdomain.com. will be our email gateway.

I've set up two security associations(in and out) on two hosts, and then set up two policies per host that should filter traffic to those SA's. Yet when I try to ping one host from the other I get no response, meaning that the filters on one side work and drop unprotected packets, but both hosts are configured to communicate using ipsec. Can anyone point me in the right direction?

View 10 Replies View RelatedI have set up SSH and redirected the ssh server to listen on another port other than 22 for a bit of added security.
Now in hosts.deny I have:
ALL : ALL
In hosts.allow I have:
SSH : ip_address_of_client
I can no longer connect. I get the message: ssh_exchange_identification: Connection closed by remote host.
When I change hosts.allow to read:
ALL : ip_address_of_client
I can successfully connect the server.
However, I only want to allow SSH access in hosts.allow. What is the correct syntax?
I have tried and failed with each one of these:
SSH : ip_address:port_number
SSH2 : ipaddress

Well, as many proxy applications, GNOME Network Proxy Preferences only allow to ignore hosts. What I want to do is exactly the opposite. I only want to use the proxy for few sites. Is it possible to define only the allowed hosts in any way?
PS: I know FoxyProxy add-on for Firefox does this, but 1)I don't use Firefox and 2)I want the proxy settings system wide not only for browser.
Is 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?
