![]() As saving a new configuration would override any manual edits. The setback with manually modifying the nf file is that it then prevents you from using the Firewall tab in the IceFloor interface. So it looks like the set skip on lo0 line has some issues. After reloading with this modified configuration, I was successfully able to access my web server via my DNS name (problem solved). On a hunch, I decided to comment out that line and add a new rule (just after the table include): pass quick on lo0. Every other piece of lo0 appeared unhindered by the pf rules. What I have done so far is that I have activated SonarLint support via changing pom.xml of alpha, and have used. At first, this seems like a very standard, welcomed line (see ). We have created a plugin which includes a bunch of Sonar Java custom rules for alpha, called alpha-custom-java-rules, and right now I would like to apply these rules to SonarLint. The default IceFloor configuration ( /Library/IceFloor/nf) is generated with a line that has set skip on lo0. Packets were, however, found with tcpdump -nvvvi lo0 tcp and port 80, thus confirming that the traffic was (as expected) happening on lo0. However, doing a tcpdump -nvvvi en0 tcp and port 80 showed that no packets were actually traveling on en0. The log entry contains some puzzling information, specifically the block in on en0, which leads you to believe something is happening on interface en0. Your machine's routing table ( netstat -r) has an entry for your DNS name that points to localhost on the lo0 interface. It has to do with how your DNS name is handled locally. It has nothing to do with the no-route or anything in the visible ruleset. The inbound connection is what is blocked. You can confirm that rule's number by running pfctl -gsr as root. ![]() To answer your first question, which one the rule 7/0(match) is: It is the "Generic_blocks_(IPv4)" rule automatically added by IceFloor to block and log all non-explicitly authorized traffic. I too was facing this issue and it took quiet a bit of testing and tcpdump to figure it all out.

And why it is not allowed to connect from localhost to the public key (on any open ports)? Has it something to do with the no-route f rule? Or the two Generic_blocks_-rules? Here is the log I get (x.x.x.x is the public IP of the host): rule 7/0(match): block in on en0: x.x.x.x.80 > x.x.x.x.64460: Flags, seq 1, ack 1, win 65535, length 0Īnd here is the list of rules $ sudo pfctl -s rules ![]() The connection from the machine to localhost/127.0.0.1 works. I can connect to http/port 80 from the internet, but not from the machine itself using the public IP. Everything seems to be fine except that I can not connect to the system using the DNS name or the public IP from localhost. First make sure to compile noImportsRule.I have set up pf using IceFloor on my OSX 10.9 system running Server 3.0.2. We still need to hook up this new rule to TSLint. To see what your Typescript file or snippet looks like as an AST, visit ( note: current version of TypeScript may not be supported, yet). For reference, the base walker can be found in syntaxWalker.ts. So the rule walkers only need to override the appropriate visitor methods to enforce its checks. Given a walker, TypeScript’s parser visits the AST using the visitor pattern. Import * as Lint from " tslint " import * as ts from " typescript " import * as tsutils from ' tsutils ' export class Rule extends Lint. Now, let us first write the rule in TypeScript: The exported class must always be named Rule and extend from.Rule files must contain the suffix Rule.Rule files are always camel-cased ( camelCasedRule.ts).Rule identifiers are always kebab-cased.Rules are referenced in tslint.json with their kebab-cased identifier, so "no-imports": true would configure the rule. Let us name the rule file noImportsRule.ts. Let us take the example of how to write a new rule to forbid all import statements (you know, for science). New rules can be written in either TypeScript or JavaScript if written in TypeScript, the code must be compiled to JavaScript before invoking TSLint. TSLint’s internal rules are itself written to be pluggable, so adding a new rule is as simple as creating a new rule file named by convention. ![]() However, users are also allowed to write their own rules, which allows them to enforce specific behavior not covered by the core of TSLint. TSLint ships with a set of core rules that can be configured.
