• How to unblacklist an IP at Google?

  - by DJRayon

  I own a small business with two servers for webhosting. When setting up the primary (CentOS 5.5 + WHM, secondary is WHM DNS Only) server I kinda messed up the firewall, so the hackers could send stuff from my server. My primary IP is x.y.29.218. Anyway - I got blacklisted in several places, but now those blacklistings are gone. For a week or so, but Google still has my IP blacklisted. I handling serious damages because of that. Many clients want to switch from my hosting, etc. I've fixed the hole with CSF firewall SMTP_BLOCK option and enabled also the WHM SMTP TEAK Currently all I see from the Main Email View Mail Statistics (Errors section) in WHM is rows and rows of the following message removed-the-email-address-for-security R=lookuphost T=remote_smtp: SMTP error from remote mail server after end of data: host aspmx.l.google.com [a.b.39.27]: 550-5.7.1 [x.y.29.218 1] Our system has detected an unusual rate of\n550-5.7.1 unsolicited mail originating from your IP address. To protect our\n550-5.7.1 users from spam, mail sent from your IP address has been blocked.\n550-5.7.1 Please visit http://www.google.com/mail/help/bulk_mail.html to review\n550 5.7.1 our Bulk Email Senders Guidelines. h24si3868764fas.171 What are my options? I have one IP free. How can I configure Exim to send mail from that IP? My brain is like constantly blowing up because of this problem. Please someone, who has any knowledge how to deal with the current situation, please give me some kind of help - any help, suggestions, etc. I've tried everything I know, and I still don't know much, because this is the first time (I just started to webhost, etc) I deal with real physical servers not some kind of pre-setup VPS solution. Many - many thanks, whoever has time to offer some help.

• Outbound mail issue during Exchange 2003 migration

  - by user27574

  Dear all, I am having an outbound email issue during the Exch 03 migration. Basically, we are migrating Exch03 to new hardware, both servers are Server 03 based. Everything runs smooth while setting up and installing Exch 03 on the new box. Public folders are all replicated. My issues are shown below.... 1) After starting to move users' mailboxes to new Exch 03, they receive some undeliverable mail and bounced back mail from some vendors, then I move few users back to test around, they have no problem at all after moving back to old Exch 03. 2) Another issue is our company has Blackberry users, we don't have BES. Under each user's mailboxes, we have forward rule setup, so that both user inbox and BB can receive email. User who is moved to the new Exch 03 server, they can only send email to the BB user's inbox, mail cannot be forwarded to BB at all, smtp queue stacks up and keep trying until the time is expired. Since not all emails that the users send out from the new Exch have problem, I am not able to narrow down what is the issue here. Can anyone give me some ideas? Could this be MX record / Reversed DNS relate? Or firewall NAT rule setting? Thanks.

• append $myorigin to localpart of 'from', append different domain to localpart of incomplete recipient address

  - by PJ P

  We have been having some trouble getting Postfix to behave in a very specific fashion in which sender and recipient addresses with only a localpart (i.e. no @domain) are handled differently. We have a number of applications that use mailx to send messages. We would like to know the username and hostname of the sending party. For example, if root sends an email from db001.company.local, we would like the email to be addressed from [email protected]. This is accomplished by ensuring $myorigin is set to $myhostname. We also want unqualified recipients to have a different domain appended. For example, if a message is sent to 'dbadmin' it should qualify to '[email protected]'. However, by the nature of Postfix and $myorigin, an unqualified recipient would instead qualify to [email protected]. We do not want to adjust the aliases on all servers to forward appropriately. (in fact, every possible recipient doesn't have an entry in /etc/passwd) All company employees have mailboxes on Exchange, which Postfix eventually routes to, and no local Linux/Unix mailboxes are used or access. We would love to tell our application owners to ensure they use a fully qualified email address for all recipients, but the powers that be dictate that any negligence must be accommodated. If we were to keep $myorigin equal to $myhostname, we could resolve this issue by having an entry such as the following in 'recipient_canonical_maps': @$myorigin @company.com However, unfortunately, we cannot use variables in these map files. We also want to avoid having to manually enter and maintain the actual hostname in 'recipient_canonical_maps' for each server. Perhaps once our servers are 'puppetized' we can dynamically adjust this file, but we're not there yet. After an afternoon of fiddling I've decided to reach out. Any thoughts? Thanks in advance.

• Thunderbird does not delete messages from the POP server

  - by Max888

  Thunderbird does not delete messages from the POP server. I am a Yahoo Plus user and I can download messages from the inbox in Thunderbird from the Yahoo POP3 server. However, I want to delete read messages directly on the email client rather than go to Yahoo mail. When I do this, emails are still on the server In accounts setting, I have the following options ticked: -Automatically download new messages -Leave messages on server, Until I delete them Thanks for any guidance Update: Thanks for the replies so far. Some clarification: I do want to keep some messages on Yahoo for filling them in my online folders, hence the reason I do not download ALL my messages to Tbird and delete server message automatically **Update 2: Cracked it!! OK, boys and girls, here is the way to do it. Go to Options- Advanced - Config Editor find the Name 'mail . pop3 . deleteFromServerOnMove' Set it to True True: Delete the copy of the message on the POP3 server if you move or delete the message. False(default): Only delete the copy of the message on the POP3 server if you delete the message. That's it, restart Thunderbird. You need to press 'Get Mail' everytime you want to sync with the email server, in order for you to make sure messages in the application is in sync with the email server.**

• Too many concurrent connections Exchange 2010. What else is there to check?

  - by hydroparadise

  I thought that I had this under control before. But for some reason during our last email marketing promo, I start receiving from our mass email client (built in house).. The message could not be sent to the SMTP server. The transport error code is 0x800ccc67. The server repsonse was 421 4.3.2 The maximum number of concurrent connections has exceeded a limit, closing transmission channel again. There's several places I've checked to make sure that wouldn't be an issue. First I checked that receive connector was set to receive an adequate number of connections on our relay connector (1000 connections). Then, I would later find out about Throttling Policies. I created one and set all the properties I knew to set in terms of the policy following properties to 1000; EWSMaxConcurrency, OWAMaxConcurrency, CPAMaxConcurrency, and CPAMaxConcurrency. Still, the email client starts receiving the error shortly after 100 has been sent and takes about 15-30 seconds. The process is then repeatable, but still the error gets received at the same spot everytime. Is there a rate setting that I am missing? Was there a windows update that I missed looking at? Should the software have it's own throttling feature?

• How can visiting a webpage infect your computer?

  - by Cybis

  My mother's computer recently became infected with some sort of rootkit. It began when she received an email from a close friend asking her to check out some sort of webpage. I never saw it, but my mother said it was just a blog of some sort, nothing interesting. A few days later, my mother signed in on the PayPal homepage. PayPal gave some sort of security notice which stated that to prevent fraud, they needed some additional personal information. Among some of the more normal information (name, address, etc.), they asked for her SSN and bank PIN! She refused to submit that information and complained to PayPal that they shouldn't ask for it. PayPal said they would never ask for such information and that it wasn't their webpage. There was no such "security notice" when she logged in from a different computer, only from hers. It wasn't a phishing attempt or redirection of some sort, IE clearly showed an SSL connection to https://www.paypal.com/ She remembered that strange email and asked her friend about it - the friend never sent it! Obviously, something on her computer was intercepting the PayPal homepage and that email was the only other strange thing to happen recently. She entrusted me to fix everything. I nuked the computer from orbit since it was the only way to be sure (i.e., reformatted her hard drive and did a clean install). That seemed to work fine. But that got me wondering... my mother didn't download and run anything. There were no weird ActiveX controls running (she's not computer illiterate and knows not to install them), and she only uses webmail (i.e., no Outlook vulnerability). When I think webpages, I think content presentation - JavaScript, HTML, and maybe some Flash. How could that possibly install and execute arbitrary software on your computer? It seems kinda weird/stupid that such vulnerabilities exist.

• fail2ban regex working but no action being taken

  - by fpghost

  I have the following snippet of fail2ban configuration on Ubuntu 13.10 server: #jail.conf [apache-getphp] enabled = true port = http,https filter = apache-getphp action = iptables-multiport[name=apache-getphp, port="http,https", protocol=tcp] mail-whois[name=apache-getphp, dest=root] logpath = /srv/apache/log/access.log maxretry = 1 #filter.d/apache-getphp.conf [Definition] failregex = ^<HOST> - - (?:\[[^]]*\] )+\"(GET|POST) /(?i)(PMA|phptest|phpmyadmin|myadmin|mysql|mysqladmin|sqladmin|mypma|admin|xampp|mysqldb|mydb|db|pmadb|phpmyadmin1|phpmyadmin2|cgi-bin) ignoreregex = I know the regex is good, because if I run the test command on my access.log: fail2ban-regex /srv/apache/log/access.log /etc/fail2ban/filter.d/apache-getphp.conf I get a SUCCESS result with multiple hits, and in my log I see entries like 187.192.89.147 - - [13/Apr/2014:11:36:03 +0100] "GET /phpTest/zologize/axa.php HTTP/1.1" 301 585 "-" "-" 187.192.89.147 - - [13/Apr/2014:11:36:03 +0100] "GET /phpMyAdmin/scripts/setup.php HTTP/1.1" 301 593 "-" "-" Secondly I know email is configured correctly, as each time I service fail2ban restart I get an email for each of the filters stopping/starting. However despite all this no action seems to be taken when one of these requests comes in. No email with whois, and no entries in iptables. What possibly could be preventing fail2ban from taking action? (everything looks in order in fail2ban-client -d and I can see the chains have loaded with iptables -L)

• VPS to replace MobileMe or Google Apps.

  - by Alex

  All, Yes, this has been touched on in other questions, but I can't find something similar enough. I currently have Google Apps hosting personal email, calendars, contacts, etc. I do like the other google services, but they're outside of Apps. One of the little google irritations that I have to maintain a separate account for Picassa, etc. So, I'm thinking about moving myself away from Google, but purely for personal, privacy type issues. Do I really like the ads, the email snooping, etc? I've had, and liked MobileMe, back when it was iTools, and then .Mac, but it doesn't offer that much really. How easily can I replicate it all on a VPS? I don't want to host it myself at home, I'd lose all the wonderful datacenter goodness. THis isn't about personal geekery in my own basement, just about taking a little control back from Google. So, email is fine running an IMAP server, a nice front-end, etc. What about Calendars and Contacts? And, how easily can it be setup to sync to the desktop and iPhone? Thanks.

• Automated Syslog Error Solution Finder

  - by Dru

  Any automated syslog solution finding frameworks? I want my central syslog server to email a list of problems, their severity and suggested solutions. There have been several questions about centralising system logs and alternative log analysis systems, but I don't get the impression that any of them help with issue resolution. A little background: At work I am now literally doing the work of two people, and both jobs have expanded beyond their initial frameworks. It is not so bad as I have helpers, but they are little more than smart monkeys. While one of my predecessors [I have two, that is how I know I have the jobs of two people] set-up logwatch to email its results out, my monkeys don't have the skills necessary to identify unimportant data. This has caused all of them, and myself sadly, to setup email filters and ignore the whole thing until something goes "bang". It would be handy to have someone else tell them what is important, what is connected, and to suggest a few ways to resolve the issue (I could train then to research the solution first, ha!). My reading of the Splunk and Octopussy sites indicates that I still need to bring my own highly trained monkey to the party. Which I am several years from having.

• Postfix relay all mail through SES except for one sending domain / address

  - by Kevin

  I'm thinking this is really really super simple, but I can't figure out what I need to do. I don't mess with Postfix much (Just let it run and do its thing) so I've got no idea where to even start with this. We have postfix currently configured to relay all mail out through SES using the code below. We need to modify this so that emails sent from one of our domains (domain.com) DO NOT go through SES. Everything else should continue to flow out through the SES connection. I'm assuming this is like a one line thing but my google skills are not helping me at all. relayhost = email-smtp.us-east-1.amazonaws.com:25 smtp_sasl_auth_enable = yes smtp_sasl_security_options = noanonymous smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_use_tls = yes smtp_tls_security_level = encrypt smtp_tls_note_starttls_offer = yes smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt smtp_destination_concurrency_limit = 450 Update I have created sender_transport file in /etc/postfix. In it is @domain.com smtp: I then ran this through postmap and placed sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transport above the above block of code and restarted postfix, but still all email is going out through SES. Log after sending Oct 22 14:38:48 web postfix/smtp[19446]: 4B19D640002: to=<[email protected]>, relay=email-smtp.us-east-1.amazonaws.com[54.243.47.187]:25, delay=1.4, delays=0.01/0/0.92/0.44, dsn=2.0.0, status=sent (250 Ok 00000141e21b181f-ee6f7c4f-f0f5-4b0f-ba69-2db146a4f988-000000) Oct 22 14:38:48 web postfix/qmgr[19435]: 4B19D640002: removed I don't think this log is what you're looking for, but it's the only thing that is logged when mail goes out, and this is with me running /usr/sbin/postfix -v start manually and not with the init script.

• Can a Windows Domain play along with a Hosted Exchange service?

  - by benzado

  I'm setting up a computer network for a small (10-20 people) company. They are currently using a Hosted Exchange service they are totally happy with. Other than that, they are starting from scratch (office doesn't even have furniture yet). They will need some kind of file sharing server set up in their office. If I set up a machine as a file server and nothing more, users will have three passwords to deal with: local machine, file server, and email. If I set up a Domain Controller, identities for local machine and file server will be the same. But what about the Hosted Exchange server? Must the users have a separate email password, or is it possible to combine the two? (I realize it might depend on the specific hosting provider, but is it possible?) If not, it seems like I have these options: Deal with it: users have a separate email password. Host Exchange on the local server: more than they want to manage in-house? Purchase a hosted VPS, make it part of the domain, and host Exchange there. (Or can/should a VPS be a domain controller?) I realize I have a lot of questions in there. The main one: is there any reason to use a Hosted Exchange service if I'm setting up other Windows services?

• Sending eMails in a external subnet in vmware ESXi

  - by user80658

  This might be a bit hard for me to explain - and it is a pretty individual situation. I got a native server at Hetzner (www.hetzner.de). The public IP is 88.[...].12. I got ESXi running on this server. I can access the esxi console by the public ip, but none of the virtual machines. That's why I bought a public subnet with 8 (6 usable) IPs (46.[...]) and an additional public ip (88.[...].26). This additional public ip belongs to the first virtual maschine - a firewall appliance - which is connected to the WAN. This need to be done this way - since it is the official way by hetzner. My 46. subnet is behind the firewall. I got a virtualmin server with dovecot imap/pop3 server. When sending a email, most provider (gmail) will accept those mails, but a lot will put it into spam (aol). My theory is: The MX line of my domain says of course the ip of the virtual machine (46.[...]), but in the raw email it says that email is sent by the ip of the firewall (88.[...].26), which doesnt sound trustworthy. A solution would be if the firewall could handle mail, but it simply cant. How can I prevent this problem? Thanks.

• #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

  - by gtaylor85

  I've searched serverfault and found this question pop-up quite a bit. Unfortunately others problems aren't exactly like mine, and because I'm a true beginner I wanted some more "specific to me" help. If you don't mind. I just set-up a new computer for a user. Copied over her auto-populate and archive emails. Her email, for the most part, works fine. But when she tries to send anything to [email protected] she gets the #550 5.1.1 error. If she uses the exchange webapp she does not have the issue. I can send email to BSMITH, and so can everyone else. The user, as far as I can tell from the EMC reports, is the only person having emails sent back to them and only from BSMITH. I have googled the crap out of this, and attempted some of the solutions to no avail. I've looked for the bmith account in the disabled accounts and copied and attempted to add "IMCEAEX-_O=CHILD+20STUDY+20CENTER_OU=FIRST+20ADMINISTRATIVE+20GROUP_CN=RECIPIENTS_CN=BSMITH@mydomain.com" as an X500 email. I honestly am just following instructions though and I don't really understand what it is I'm doing. Diagnostic information for administrators: Generating server: FS2.FS1D.local IMCEAEX-_O=CHILD+20STUDY+20CENTER_OU=FIRST+20ADMINISTRATIVE+20GROUP_CN=RECIPIENTS_CN=BSMITH@mydomain.com #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ## BTW I love this site and only found out about it a few weeks ago. My girlfriend now loves the photo.stackexchange. So thanks for such a helpful community.

• Software for RAID Failure Alerts?

  - by QF_Developer

  I have two 256 GB Samsung 840 Pro SSD disks in a RAID 1 array. I would like to receive a notification if one of the disks in the array fails. Can anybody recommend an application I can install on the server to fire an email if such an event occurs? Here are some additional specs: Supermicro X9SCM-IIF motherboard utilising the hardware RAID controller. OS = Windows 2012 Standard Also is it possible to simulate a disk failure by pulling it out of the bay? SSDs appear to fail close together when in a mirrored config so I'd like to know ASAP if one goes down so I can swap them out with minimum delay. UPDATE 26th June 2013 ------------------------ None of the software that ships with the Supermicro X9SCM-* motherboards offer support for RAID monitoring. As has been pointed out here, these boards are built on an Intel chipset for RAID and so I installed Intel Rapid Storage Technology that supports automated email notifications on RAID failure http://www.intel.com/support/chipsets/imsm/sb/cs-020784.htm One small issue, the software only allows you to send email notifications without SMTP authentication. There's a bunch of different workarounds here: http://communities.intel.com/thread/30771

• puppet execution of a python script where os.system(...) command is not working

  - by philippe

  I am trying to manage Unix users with puppet. Puppet provides enough tools to create accounts and provide authorized_keys files for instance, but no to set up user password, and it tell to the user. What I have done is a python script which generate a random password and send it to the user by email. The problem is, it is not possible to launch passwd Unix command with python, I have then written a bash script with the command: echo -ne "$password\n$password\n" | passwd $user passwd -e $user Launched manually, the script works fine and the created user has its password sent by email. But when puppet launches it, only the python script gets executed, as if the os.system('/bin/bash my_bash_script') is ignored. No error is displayed. And the user gets its password, but the passwd commands are not launched. Is there any limitation with puppet preventing to perform what I described? Or, how can I otherwise change the user account, its expiration, and send password by email? I can provide more information, but right now, I don't know which are accurate. Many thanks!

• Can my employer force me to backup my personal machine? [closed]

  - by Eric B

  Here's the background: Approximately 1.25 years ago, the company I work for was acquired by a larger 400 person company. Before acquisition (and today still) we are all remote employees using our own personal hardware for work-related duties (coding, email, etc). We are approximately 15 employees within the larger organization. Some time after acquisition, the now owning company was slapped with a civil lawsuit. Part of this lawsuit (discovery) is requiring them to retrieve & store from us any related information. Because we were a separate company up until acquisition, there is a high probability that our personal machines might contain information about what the lawsuit alleges (email, documents, chat logs?, etc). Obviously, this depends largely on the person's job function (engineer vs. customer support vs. CEO). All employees are being required to comply. Since acquisition (1.25 yrs), the new company has not provided us with company laptops/desktops. We continue to use personal hardware, licenses, etc for work. Email is via POP3s and not hanging around on the mail server - it's on everyone's client. Documents are spread across personal machines. So, now they want us each to backup our complete personal machines. They are allowing us to create a "personal" folder where we can place personal documents. That single folder will be excluded from backup. Of course, that means total re-arrangement of documents, etc. For most of us, 99% of the data on the machine is NOT related to work. So, what's the consensus? Should we comply? What is their recourse if we do not?

• MEB: Taking Incremental Backup using last successful backup

  - by Sagar Jauhari

  Introduction In MySQL Enterprise Backup v3.7.0 (MEB 3.7.0) a new option '–incremental-base' was introduced. Using this option a user can take in incremental backup without specifying the '–start-lsn' option. Description of this option can be found here. Instead of '–start-lsn' the user can provide the location of the last full backup or incremental backup using the 'dir:' prefix. MEB would extract the end LSN of this backup from the mysql.backup_history table as well as the backup_variables.txt file (for verification) to use it as the start LSN of the incremental backup. Because of popular demand, in MEB 3.7.1 the option '-incremental-base' has been extended further. The idea is to allow the user to take an incremental backup as easily as possible using the '–incremental-base' option. With the new option MEB queries the backup_history table for the last successful backup and uses its end LSN as the start LSN for the new incremental backup. It should be noted that the last successful backup is used irrespective of the location of the backup. Details A new prefix 'history:' has been introduced for the –incremental-base option and currently the only permissible value is the string "last_backup". So using the new option an incremental backup can be taken with the following command: $ mysqlbackup --incremental --incremental-backup-dir=/media/mysqlbackup-repo/ --incremental-base=history:last_backup backup When MEB attempts to extract the end LSN of the last successful backup from the mysql.backup_history table, it also scans the corresponding backup destination for the old backup and tries to read the meta files at this backup destination. If a valid backup still exists at the backup destination and the meta files can be read, MEB compares the end LSN found in the mysql.backup_history table with the end LSN found in the backup meta files of the old backup. Assuming that the host MySQL server is alive and mysql.backup_history can be accessed by MEB, the behaviour of MEB with respect to verification of the old end LSN can be summarized as follows: If 'BD' is the backup destination of the last successful backup in mysql.backup_history table and 'BHT' is the mysql.backup_history table if can_read_files_at_BD:     if end_lsn_found_at_BD == end_lsn_of_last_backup_in_BHT:         continue_with_backup()     else         return_with_error() else     continue_with_backup() Advantages Apart from ease of usability an important advantage of this option is that the user can do repeated incremental backups without changing the command line. This is possible using the '–with-timestamp' option along with this new option. For example, the following command $ mysqlbackup --with-timestamp --incremental --incremental-backup-dir=/media/mysqlbackup-repo/ --incremental-base=history:last_backup backup  can be used to perform successive incremental backups in the directory /media/mysqlbackup-repo . Limitations The option '--incremental-base=history:last_backup' should not be used when the user takes different kinds of concurrent backups on the same MySQL server (say different partial backups at multiple locations). should not be used after any temporary or experimental backups performed on the server (which where successful!). needs to be used with precaution since any intermediate successful backup without the –no-connection will be used as the base backup for the next incremental backup.  will give an error in case a valid backup exists at the location of the last successful backup and whose end LSN is different from that of the last successful backup found in the backup_history table.

• JDK 7u25: Solutions to Issues caused by changes to Runtime.exec

  - by Devika Gollapudi

  The following examples were prepared by Java engineering for the benefit of Java developers who may have faced issues with Runtime.exec on the Windows platform. Background In JDK 7u21, the decoding of command strings specified to Runtime.exec(String), Runtime.exec(String,String[]) and Runtime.exec(String,String[],File) methods, has been made more strict. See JDK 7u21 Release Notes for more information. This caused several issues for applications. The following section describes some of the problems faced by developers and their solutions. Note: In JDK 7u25, the system property jdk.lang.Process.allowAmbigousCommands can be used to relax the checking process and helps as a workaround for some applications that cannot be changed. The workaround is only effective for applications that are run without a SecurityManager. See JDK 7u25 Release Notes for more information. Note: To understand the details of the Windows API CreateProcess call, see: http://msdn.microsoft.com/en-us/library/windows/desktop/ms682425%28v=vs.85%29.aspx There are two forms of Runtime.exec calls: with the command as string: "Runtime.exec(String command[, ...])" with the command as string array: "Runtime.exec(String[] cmdarray [, ...] )" The issues described in this section relate to the first form of call. With the first call form, developers expect the command to be passed "as is" to Windows where the command needs be split into its executable name and arguments parts first. But, in accordance with Java API, the command argument is split into executable name and arguments by spaces. Problem 1: "The file path for the command includes spaces" In the call: Runtime.getRuntime().exec("c:\\Program Files\\do.exe") the argument is split by spaces to an array of strings as: c:\\Program, Files\\do.exe The first element of parsed array is interpreted as the executable name, verified by SecurityManager (if present) and surrounded by quotations to avoid ambiguity in executable path. This results in the wrong command: "c:\\Program" "Files\\do.exe" which will fail. Solution: Use the ProcessBuilder class, or the Runtime.exec(String[] cmdarray [, ...] ) call, or quote the executable path. Where it is not possible to change the application code and where a SecurityManager is not used, the Java property jdk.lang.Process.allowAmbigousCommands could be used by setting its value to "true" from the command line: -Djdk.lang.Process.allowAmbigousCommands=true This will relax the checking process to allow ambiguous input. Examples: new ProcessBuilder("c:\\Program Files\\do.exe").start() Runtime.getRuntime().exec(new String[]{"c:\\Program Files\\do.exe"}) Runtime.getRuntime().exec("\"c:\\Program Files\\do.exe\"") Problem 2: "Shell command/.bat/.cmd IO redirection" The following implicit cmd.exe calls: Runtime.getRuntime().exec("dir temp.txt") new ProcessBuilder("foo.bat", "", "temp.txt").start() Runtime.getRuntime().exec(new String[]{"foo.cmd", "", "temp.txt"}) lead to the wrong command: "XXXX" "" temp.txt Solution: To specify the command correctly, use the following options: Runtime.getRuntime().exec("cmd /C \"dir temp.txt\"") new ProcessBuilder("cmd", "/C", "foo.bat temp.txt").start() Runtime.getRuntime().exec(new String[]{"cmd", "/C", "foo.cmd temp.txt"}) or Process p = new ProcessBuilder("cmd", "/C" "XXX").redirectOutput(new File("temp.txt")).start(); Problem 3: "Group execution of shell command and/or .bat/.cmd files" Due to enforced verification procedure, arguments in the following calls create the wrong commands.: Runtime.getRuntime().exec("first.bat && second.bat") new ProcessBuilder("dir", "&&", "second.bat").start() Runtime.getRuntime().exec(new String[]{"dir", "|", "more"}) Solution: To specify the command correctly, use the following options: Runtime.exec("cmd /C \"first.bat && second.bat\"") new ProcessBuilder("cmd", "/C", "dir && second.bat").start() Runtime.exec(new String[]{"cmd", "/C", "dir | more"}) The same scenario also works for the "&", "||", "^" operators of the cmd.exe shell. Problem 4: ".bat/.cmd with special DOS chars in quoted params” Due to enforced verification, arguments in the following calls will cause exceptions to be thrown.: Runtime.getRuntime().exec("log.bat \"error new ProcessBuilder("log.bat", "error Runtime.getRuntime().exec(new String[]{"log.bat", "error Solution: To specify the command correctly, use the following options: Runtime.getRuntime().exec("cmd /C log.bat \"error new ProcessBuilder("cmd", "/C", "log.bat", "error Runtime.getRuntime().exec(new String[]{"cmd", "/C", "log.bat", "error Examples: Complicated redirection for shell construction: cmd /c dir /b C:\ "my lovely spaces.txt" becomes Runtime.getRuntime().exec(new String[]{"cmd", "/C", "dir \b \"my lovely spaces.txt\"" }); The Golden Rule: In most cases, cmd.exe has two arguments: "/C" and the command for interpretation.

• Subterranean IL: Compiling C# exception handlers

  - by Simon Cooper

  An exception handler in C# combines the IL catch and finally exception handling clauses into a single try statement: try { Console.WriteLine("Try block") // ... } catch (IOException) { Console.WriteLine("IOException catch") // ... } catch (Exception e) { Console.WriteLine("Exception catch") // ... } finally { Console.WriteLine("Finally block") // ... } How does this get compiled into IL? Initial implementation If you remember from my earlier post, finally clauses must be specified with their own .try clause. So, for the initial implementation, we take the try/catch/finally, and simply split it up into two .try clauses (I have to use label syntax for this): StartTry: ldstr "Try block" call void [mscorlib]System.Console::WriteLine(string) // ... leave.s End EndTry: StartIOECatch: ldstr "IOException catch" call void [mscorlib]System.Console::WriteLine(string) // ... leave.s End EndIOECatch: StartECatch: ldstr "Exception catch" call void [mscorlib]System.Console::WriteLine(string) // ... leave.s End EndECatch: StartFinally: ldstr "Finally block" call void [mscorlib]System.Console::WriteLine(string) // ... endfinally EndFinally: End: // ... .try StartTry to EndTry catch [mscorlib]System.IO.IOException handler StartIOECatch to EndIOECatch catch [mscorlib]System.Exception handler StartECatch to EndECatch .try StartTry to EndTry finally handler StartFinally to EndFinally However, the resulting program isn't verifiable, and doesn't run: [IL]: Error: Shared try has finally or fault handler. Nested try blocks What's with the verification error? Well, it's a condition of IL verification that all exception handling regions (try, catch, filter, finally, fault) of a single .try clause have to be completely contained within any outer exception region, and they can't overlap with any other exception handling clause. In other words, IL exception handling clauses must to be representable in the scoped syntax, and in this example, we're overlapping catch and finally clauses. Not only is this example not verifiable, it isn't semantically correct. The finally handler is specified round the .try. What happens if you were able to run this code, and an exception was thrown? Program execution enters top of try block, and exception is thrown within it CLR searches for an exception handler, finds catch Because control flow is leaving .try, finally block is run The catch block is run leave.s End inside the catch handler branches to End label. We're actually running the finally before the catch! What we do about it What we actually need to do is put the catch clauses inside the finally clause, as this will ensure the finally gets executed at the correct time (this time using scoped syntax): .try { .try { ldstr "Try block" call void [mscorlib]System.Console::WriteLine(string) // ... leave.s End } catch [mscorlib]System.IO.IOException { ldstr "IOException catch" call void [mscorlib]System.Console::WriteLine(string) // ... leave.s End } catch [mscorlib]System.Exception { ldstr "Exception catch" call void [mscorlib]System.Console::WriteLine(string) // ... leave.s End } } finally { ldstr "Finally block" call void [mscorlib]System.Console::WriteLine(string) // ... endfinally } End: ret Returning from methods There is a further semantic mismatch that the C# compiler has to deal with; in C#, you are allowed to return from within an exception handling block: public int HandleMethod() { try { // ... return 0; } catch (Exception) { // ... return -1; } } However, you can't ret inside an exception handling block in IL. So the C# compiler does a leave.s to a ret outside the exception handling area, loading/storing any return value to a local variable along the way (as leave.s clears the stack): .method public instance int32 HandleMethod() { .locals init ( int32 retVal ) .try { // ... ldc.i4.0 stloc.0 leave.s End } catch [mscorlib]System.Exception { // ... ldc.i4.m1 stloc.0 leave.s End } End: ldloc.0 ret } Conclusion As you can see, the C# compiler has quite a few hoops to jump through to translate C# code into semantically-correct IL, and hides the numerous conditions on IL exception handling blocks from the C# programmer. Next up: catch-all blocks, and how the runtime deals with non-Exception exceptions.

• methods DSA_do_verify and SHA1 (OpenSSL library for Windows)

  - by Rei

  i am working on a program to authenticate an ENC signature file by using OpenSSL for windows, and specifically methods DSA_do_verify(...) and SHA1(...) hash algorithm, but is having problems as the result from DSA_do_verify is always 0 (invalid). I am using the signature file of test set 4B from the IHO S-63 Data Protection Scheme, and also the SA public key (downloadable from IHO) for verification. Below is my program, can anyone help to see where i have gone wrong as i have tried many ways but failed to get the verification to be valid, thanks.. The signature file from test set 4B // Signature part R: 3F14 52CD AEC5 05B6 241A 02C7 614A D149 E7D6 C408. // Signature part S: 44BB A3DB 8C46 8D11 B6DB 23BE 1A79 55E6 B083 7429. // Signature part R: 93F5 EF86 1FF6 BA6F 1C2B B9BB 7F36 0C80 2F9B 2414. // Signature part S: 4877 8130 12B4 50D8 3688 B52C 7A84 8E26 D442 8B6E. // BIG p C16C BAD3 4D47 5EC5 3966 95D6 94BC 8BC4 7E59 8E23 B5A9 D7C5 CEC8 2D65 B682 7D44 E953 7848 4730 C0BF F1F4 CB56 F47C 6E51 054B E892 00F3 0D43 DC4F EF96 24D4 665B. // BIG q B7B8 10B5 8C09 34F6 4287 8F36 0B96 D7CC 26B5 3E4D. // BIG g 4C53 C726 BDBF BBA6 549D 7E73 1939 C6C9 3A86 9A27 C5DB 17BA 3CAC 589D 7B3E 003F A735 F290 CFD0 7A3E F10F 3515 5F1A 2EF7 0335 AF7B 6A52 11A1 1035 18FB A44E 9718. // BIG y 15F8 A502 11C2 34BB DF19 B3CD 25D1 4413 F03D CF38 6FFC 7357 BCEE 59E4 EBFD B641 6726 5E5F 0682 47D4 B50B 3B86 7A85 FB4D 6E01 8329 A993 C36C FD9A BFB6 ED6D 29E0. dataServer_pkeyfile.txt (extracted from above) // BIG p C16C BAD3 4D47 5EC5 3966 95D6 94BC 8BC4 7E59 8E23 B5A9 D7C5 CEC8 2D65 B682 7D44 E953 7848 4730 C0BF F1F4 CB56 F47C 6E51 054B E892 00F3 0D43 DC4F EF96 24D4 665B. // BIG q B7B8 10B5 8C09 34F6 4287 8F36 0B96 D7CC 26B5 3E4D. // BIG g 4C53 C726 BDBF BBA6 549D 7E73 1939 C6C9 3A86 9A27 C5DB 17BA 3CAC 589D 7B3E 003F A735 F290 CFD0 7A3E F10F 3515 5F1A 2EF7 0335 AF7B 6A52 11A1 1035 18FB A44E 9718. // BIG y 15F8 A502 11C2 34BB DF19 B3CD 25D1 4413 F03D CF38 6FFC 7357 BCEE 59E4 EBFD B641 6726 5E5F 0682 47D4 B50B 3B86 7A85 FB4D 6E01 8329 A993 C36C FD9A BFB6 ED6D 29E0.
