  • Postfix configuration problem

    - by dhanya
    Can anyone help me by giving your postfix configuration file as a reference so that I can find my mistakes? I'm working on SUSE Linux Enterprise Server. My goal is to set up a mailserver in a campus network. Postfix shows it is running but no mail is sent to var/spool/mail I send mail using mail command at terminal. Here is my main.cf file, please help me finding a solution: readme_directory = /usr/share/doc/packages/postfix-doc/README_FILES inet_protocols = all biff = no mail_spool_directory = /var/mail canonical_maps = hash:/etc/postfix/canonical virtual_alias_maps = hash:/etc/postfix/virtual virtual_alias_domains = hash:/etc/postfix/virtual relocated_maps = hash:/etc/postfix/relocated transport_maps = hash:/etc/postfix/transport sender_canonical_maps = hash:/etc/postfix/sender_canonical masquerade_exceptions = root masquerade_classes = envelope_sender, header_sender, header_recipient myhostname = cmail.cetmail delay_warning_time = 1h message_strip_characters = \0 program_directory = /usr/lib/postfix inet_interfaces = all #inet_interfaces = 127.0.0.1 masquerade_domains = cetmail mydestination = cmail.cetmail, localhost.cetmail, cetmail defer_transports = mynetworks_style = subnet disable_dns_lookups = no relayhost = postfix mailbox_command = cyrus mailbox_transport = strict_8bitmime = no disable_mime_output_conversion = no smtpd_sender_restrictions = hash:/etc/postfix/access smtpd_client_restrictions = smtpd_helo_required = no smtpd_helo_restrictions = strict_rfc821_envelopes = no smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination smtp_sasl_auth_enable = no smtpd_sasl_auth_enable = no smtpd_use_tls = no smtp_use_tls = no alias_maps = hash:/etc/aliases mailbox_size_limit = 0 message_size_limit = 10240000

  • Varnish 503 Guru Mediation errors with pfsense and healthy apache

    - by Fammy
    We are running a pfsense firewall / load balancer with varnish as service, In front of Fedora linux webservers running apache. We are getting intermittent 503 guru mediation errors. We are a bit stuck scratching our heads because it is not easily repeatable. The timeouts are set to 30s (connect and first byte) but yet the 503 page will show instantly, not after 30s. Then if you refresh immediately it may very well work instantly and sometimes for a 100 refreshes. The load average on the web servers is < 1, the DB server is < 3 (all servers (web, db, pfsense/varnish) are physical rather than VM. I would have thought if the timeouts were being hit then the 503 page would only appear after 30s am I mistaken? Also when an error happens there does not appear to be any corresponding error in apache's log files. This seems to affect pages as well as images, so it is possible to have the page load fine, and for 9/10 images on the page to be fine but 1 not work An example of the varnish debug is below. It says no backend connection but I can't figure out why, if the load was high on apache I could understand it being flaky The machines are on the same gig ethernet lan 21 ReqStart c *IP-REMOVED* 33418 1274368062 21 RxRequest c GET 21 RxURL c /fashion/ 21 RxProtocol c HTTP/1.1 21 RxHeader c User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.5) Gecko/2008121622 Fedora/3.0.5-1.fc10 Firefox/3.0.5 21 RxHeader c Host: *ourdomain.com* 21 RxHeader c Accept: */* 21 RxHeader c Accept-Encoding: deflate, gzip 21 VCL_call c recv lookup 21 VCL_call c hash 21 Hash c /fashion/ 21 Hash c *ourdomain.com* 21 VCL_return c hash 21 VCL_call c miss fetch 21 FetchError c no backend connection 21 VCL_call c error restart 21 VCL_call c recv lookup 21 VCL_call c hash 21 Hash c /fashion/ 21 Hash c *ourdomain.com* 21 VCL_return c hash 21 VCL_call c miss fetch 21 FetchError c no backend connection 21 VCL_call c error restart 21 VCL_call c recv lookup 21 VCL_call c hash 21 Hash c /fashion/ 21 Hash c *ourdomain.com* 21 VCL_return c hash 21 VCL_call c miss fetch 21 FetchError c no backend connection 21 VCL_call c error deliver 21 VCL_call c deliver deliver 21 TxProtocol c HTTP/1.1 21 TxStatus c 503 21 TxResponse c Service Unavailable 21 TxHeader c Server: Varnish 21 TxHeader c Content-Type: text/html; charset=utf-8 21 TxHeader c Content-Length: 384 21 TxHeader c Accept-Ranges: bytes 21 TxHeader c Date: Wed, 11 Apr 2012 10:36:17 GMT 21 TxHeader c X-Varnish: 1274368062 21 TxHeader c Age: 0 21 TxHeader c Via: 1.1 varnish 21 TxHeader c Connection: close 21 TxHeader c X-Cache: MISS 21 Length c 384 21 ReqEnd c 1274368062 1334140577.449995041 1334140577.450334787 1.794108152 0.000282764 0.000056982

  • How can I uninstall a clustered SQL instance if the cluster has been destroyed?

    - by Bob
    First time going through this scenario, and apparently I did it very wrong. On the DB servers I deleted the cluster group that held SQL and Reporting Services. I then destroyed the cluster. Then I tried to uninstall SQL. No dice. SQL still thinks its part of the non-existant cluster and will not let me uninstall it. I went into the Maintenance menu of the SQL setup and tried to Remove Node...nope. Unless I find a way out of this I will have to rebuild the OS if I can't get SQL off the box.

Has my server been rooted? I am running fail2ban and do monitor failed ssh logins. nothing has come up. Could someone compare these hashes to their copy of Ubuntu Server (lts)? Please tell me these are false positives..... Edit: is something else like rkhunter I can run for a second scan?

  • Approach to Authenticate Clients to TCP Server

    - by dab
    I'm writing a Server/Client application where clients will connect to the server. What I want to do, is make sure that the client connecting to the server is actually using my protocol and I can "trust" the data being sent from the client to the server. What I thought about doing is creating a sort of hash on the client's machine that follows a particular algorithm. What I did in a previous version was took their IP address, the client version, and a few other attributes of the client and sent it as a calculated hash to the server, who then took their IP, and the version of the protocol the client claimed to be using, and calculated that number to see if they matched. This works ok until you get clients that connect from within a router environment where their internal IP is different from their external IP. My fix for this was to pass the client's internal IP used to calculate this hash with the authentication protocol. My fear is this approach is not secure enough. Since I'm passing the data used to create the "auth hash". Here's an example of what I'm talking about: Client IP: 192.168.1.10, Version: 2.4.5.2 hash = 2*4*5*1 * (1+9+2) * (1+6+8) * (1) * (1+0) Client Connects to Server client sends: auth hash ip version Server calculates that info, and accepts or denies the hash. Before I go and come up with another algorithm to prove a client can provide data a server (or use this existing algorithm), I was wondering if there are any existing, proven, and secure systems out there for generating a hash that both sides can generate with general knowledge. The server won't know about the client until the very first connection is established. The protocol's intent is to manage a network of clients who will be contributing data to the server periodically. New clients will be added simply by connecting the client to the server and "registering" with the server. So a client connects to the server for the first time, and registers their info (mac address or some other kind of unique computer identifier), then when they connect again, the server will recognize that client as a previous person and associate them with their data in the database.

  • Convert URI to GUID

    - by David Rutten
    What is a good way to convert a file path (URI) into a System.Guid? I'd like to minimize the possibility of a collision, but I'm happy with a reasonably unique hashing (probably never more than a few dozen/hundred items in the database)

  • Spring Security DB Authentication w/Hibernate and hashed passwords?

    - by Seth
    I'm trying to set up spring security 3 to authenticate users against my hibernate 3 database. I'm storing only sha1 hashes of the passwords in the database (not plaintext). I've looked at this and this, which tell me to implement my own UserDetailsService. Unfortunately, the UserDetails that loadUserByUsername spits out seem to need the plaintext password, which I don't have. How is this usually handled? Can Spring Security actually do what I need here? Am I missing something?

  • Generate unique hashes for django models

    I want to use unique hashes for each model rather than ids. I implemented the following function to use it across the board easily. import random,hashlib from base64 import urlsafe_b64encode def set_unique_random_value(model_object,field_name='hash_uuid',length=5,use_sha=True,urlencode=False): while 1: uuid_number = str(random.random())[2:] uuid = hashlib.sha256(uuid_number).hexdigest() if use_sha else uuid_number uuid = uuid[:length] if urlencode: uuid = urlsafe_b64encode(uuid)[:-1] hash_id_dict = {field_name:uuid} try: model_object.__class__.objects.get(**hash_id_dict) except model_object.__class__.DoesNotExist: setattr(model_object,field_name,uuid) return I'm seeking feedback, how else could I do it? How can I improve it? What is good bad and ugly about it?

  • Logging IP address for uniqueness without storing the IP address itself for privacy

    - by szabgab
    In a web application when logging some data I'd like to make sure I can identify data that came at differetn times but from the same IP address. On the other hand for privacy concerns as the data will be released publicly I'd like to make sure the actual IP cannot be retrieved. So I need some one way mapping of the IP addresses to some other strings that ensures 1-1 mapping. If I understand correctly then MD5, SHA1 or SHA256 could be a solution. I wonder if they are not too expensive in terms of processing needed? I'd be interested in any solution though if there is implementation in Perl that would be even better.

  • Hashing words to numbers with respect to definition

    - by thornate
    As part of a larger project, I need to read in text and represent each word as a number. For example, if the program reads in "Every good boy deserves fruit", then I would get a table that converts 'every' to '1742', 'good' to '977513', etc. Now, obviously I can just use a hashing algorithm to get these numbers. However, it would be more useful if words with similar meanings had numerical values close to each other, so that 'good' becomes '6827' and 'great' becomes '6835', etc. As another option, instead of a simple integer representing each number, it would be even better to have a vector made up of multiple numbers, eg (lexical_category, tense, classification, specific_word) where lexical_category is noun/verb/adjective/etc, tense is future/past/present, classification defines a wide set of general topics and specific_word is much the same as described in the previous paragraph. Does any such an algorithm exist? If not, can you give me any tips on how to get started on developing one myself? I code in C++.

  • Can I use a ShareThis/AddThis Button if my site's navigation relies on Hash tags in the url?

    - by John Himmelman
    I want to embed a ShareThis/AddThis button on my site but the site's navigation relies on Hash tags in the url. Each page is assigned a unique hash value (ie, http://domain.com/index.php#products). Changing the navigation/page design isn't an option. Will these service preserve the hash value (both embed JS on the page)? If they don't, what are some alternative solutions?

  • Mysql password hashing method old vs new

    - by The Disintegrator
    I'm trying to connect to a mysql server at dreamhost from a php scrip located in a server at slicehost (two different hosting companies). I need to do this so I can transfer new data at slicehost to dreamhost. Using a dump is not an option because the table structures are different and i only need to transfer a small subset of data (100-200 daily records) The problem is that I'm using the new MySQL Password Hashing method at slicehost, and dreamhost uses the old one, So i get $link = mysql_connect($mysqlHost, $mysqlUser, $mysqlPass, FALSE); Warning: mysql_connect() [function.mysql-connect]: OK packet 6 bytes shorter than expected Warning: mysql_connect() [function.mysql-connect]: mysqlnd cannot connect to MySQL 4.1+ using old authentication Warning: mysql_query() [function.mysql-query]: Access denied for user 'nodari'@'localhost' (using password: NO) facts: I need to continue using the new method at slicehost and i can't use an older php version/library The database is too big to transfer it every day with a dump Even if i did this, the tables have different structures I need to copy only a small subset of it, in a daily basis (only the changes of the day, 100-200 records) Since the tables are so different, i need to use php as a bridge to normalize the data Already googled it Already talked to both support stafs The more obvious option to me would be to start using the new MySQL Password Hashing method at dreamhost, but they will not change it and i'm not root so i can't do this myself. Any wild idea? By VolkerK sugestion: mysql> SET SESSION old_passwords=0; Query OK, 0 rows affected (0.01 sec) mysql> SELECT @@global.old_passwords,@@session.old_passwords, Length(PASSWORD('abc')); +------------------------+-------------------------+-------------------------+ | @@global.old_passwords | @@session.old_passwords | Length(PASSWORD('abc')) | +------------------------+-------------------------+-------------------------+ | 1 | 0 | 41 | +------------------------+-------------------------+-------------------------+ 1 row in set (0.00 sec) The obvious thing now would be run a mysql SET GLOBAL old_passwords=0; But i need SUPER privilege to do that and they wont give it to me if I run the query SET PASSWORD FOR 'nodari'@'HOSTNAME' = PASSWORD('new password'); I get the error ERROR 1044 (42000): Access denied for user 'nodari'@'67.205.0.0/255.255.192.0' to database 'mysql' I'm not root... The guy at dreamhost support insist saying thet the problem is at my end. But he said he will run any query I tell him since it's a private server. So, I need to tell this guy EXACTLY what to run. So, telling him to run SET SESSION old_passwords=0; SET GLOBAL old_passwords=0; SET PASSWORD FOR 'nodari'@'HOSTNAME' = PASSWORD('new password'); grant all privileges on *.* to nodari@HOSTNAME identified by 'new password'; would be a good start?

    Let's say I have two objects: User and Race. User has two attributes: first_name, last_name. And Race has three attributes: course, start_time, end_time. Now let's say I create an array of hashes like this: user_races = races.map{ |race| {:user = race.user, :race = race} } How do I then convert user_races into an array of structs, keeping in mind that I want to be able to access the attributes of both user and race from the struct element?

  • Creating a short unique string for each unique long string

    - by king.net
    I'm trying to create a url shortener system in c# and asp.net mvc. I know about hashtable and I know how to create a redirect system etc. The problem is indexing long urls in database. Some urls may have up to 4000 character length, and it seems it is a bad idea to index this kind of strings. The question is: How can I create a unique short string for each url? for example MD5 can help me? Is MD5 really unique for each string? NOTE: I see that Gravatar uses MD5 for emails, so if each email address is unique, then its MD5 hashed value is unique. Is it right? Can I use same solution for urls?

  • MD5 file processing

    - by Ric Coles
    Good morning all, I'm working on an MD5 file integrity check tool in C#. How long should it take for a file to be given an MD5 checksum value? For example, if I try to get a 2gb .mpg file, it is taking around 5 mins+ each time. This seems overly long. Am I just being impatient? Below is the code I'm running public string getHash(String @fileLocation) { FileStream fs = new FileStream(@fileLocation, FileMode.Open); HashAlgorithm alg = new HMACMD5(); byte[] hashValue = alg.ComputeHash(fs); string md5Result = ""; foreach (byte x in hashValue) { md5Result += x; } fs.Close(); return md5Result; } Any suggestions will be appreciated. Regards
