• Upgraded AGPM Server cannot connect to relocated archive

  - by thommck

  We were using the Advanced Group Policy Management (AGPM) v3.0 on out Windows Server 2008 DC. It kept the archive on the C: drive. When we upgraded to AGPM v4 we relocated the archive to the D: drive. Now when we try to look at a GPO's hisory in GPMC we get the following error Failed to connect to the AGPM Server. The following error occurred: The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs. System.ServiceModel.FaultException (80131501) You are able to click Retry or Cancel. Retry brings up the same error and Cancel takes you back to GPMC and the History tab displays "Archive not found". I installed the client on a Windows 7 computer (which is a n unsupported set up) and it could read the server archive without any issues. I followed the TechNet article "Move the AGPM Server and the Archive" but that didn't make a difference How can I tell the server where the archive is?

• Timer_EntityBody, Timer_ConnectionIdle and Connection Closed Unexpectly

  - by ihsany

  We have a windows application, it connects to a web service (XML web service hosted on a Windows 2008 Server IIS 7.5, no antivirus) and fetches some data to the client. But sometimes (around 5%-10% of the requests), it gives an error when trying to connect web service. Here is the client application error log; Exception:System.Net.WebException: The underlying connection was closed: The connection was closed unexpectedly. at System.Web.Services.Protocols.WebClientAsyncResult.WaitForResponse() at System.Web.Services.Protocols.WebClientProtocol.EndSend(IAsyncResult asyncResult, Object& internalAsyncState, Stream& responseStream) at System.Web.Services.Protocols.SoapHttpClientProtocol.EndInvoke(IAsyncResult asyncResult) at APPClient.APPFPService.WEBService.EndAddMoney(IAsyncResult asyncResult) at APPClient.BLL.ServiceAgent.AddMoneyCallback(IAsyncResult ar) From other hand, on the web server, i checked HTTP error logs and i see a long file like this; 2014-06-05 14:02:04 65.82.178.73 53798 SERVER.IP.ADDRESS 80 - - - - - Timer_ConnectionIdle - 2014-06-05 14:07:24 76.109.81.223 58985 SERVER.IP.ADDRESS 80 - - - - - Timer_ConnectionIdle - 2014-06-05 14:07:39 76.109.81.223 2803 SERVER.IP.ADDRESS 80 - - - - - Timer_ConnectionIdle - 2014-06-05 14:08:59 76.109.81.223 52656 SERVER.IP.ADDRESS 80 - - - - - Timer_ConnectionIdle - 2014-06-05 14:09:05 65.82.178.73 53904 SERVER.IP.ADDRESS 80 HTTP/1.1 POST /webservice/webservice.asmx - 2 Timer_EntityBody SYPService 2014-06-05 14:10:55 50.186.180.191 50648 SERVER.IP.ADDRESS 80 - - - - - Timer_ConnectionIdle - Here is a similar situation but it did not help me.

• Cannot connect with Cisco VPN but can connect with ShrewSoft VPN

  - by rodey

  EDIT: We connected an air card to the computer to use a different Internet connection and using the Cisco software, we were able to successfully connect to our VPN server. I just don't understand why the ShrewSoft VPN client would connect but the Cisco connection won't. I'm not our network admin so sorry if I butcher some of the terminology. I have a computer at remote site that connects to our network through Cisco VPN. It uses the Cisco VPN software to do so. The problem is that the computer at this site cannot connect to our VPN because it is getting error "Reason 412: The remote peer is no longer responding." To see if perhaps something on their network was blocking the connection, I installed the ShrewSoft VPN client on the computer, imported our .pcf file and connected with no problem. I have tried two different versions of the Cisco VPN software (4.8.0.* and 5.0.03.*) and have the same problem. I installed Wireshark on the computer and have confirmed (while trying to connect through Cisco) that the computer is trying to contact the VPN server but is not receiving a response. We are not having any other problems regarding users not being able to connect. I'm at a loss at what else to check. I'll be monitoring this and have access to the computer at any time.

• configure a Cisco ASA to use MS-CHAP v2 for RADIUS authentication

  - by DrStalker

  Cisco ASA5505 8.2(2) Windows 2003 AD server We want to configure our ASA (10.1.1.1) to authenticate remote VPN users through RADIUS on the Windows AD controller (10.1.1.200) We have the following entry on the ASA: aaa-server SYSCON-RADIUS protocol radius aaa-server SYSCON-RADIUS (inside) host 10.1.1.200 key ***** radius-common-pw ***** When I test a login using the account COMPANY\username I see the users credentials are correct in the security log, but I get the following in the windows system logs: User COMPANY\myusername was denied access. Fully-Qualified-User-Name = company.com/CorpUsers/AU/My Name NAS-IP-Address = 10.1.1.1 NAS-Identifier = <not present> Called-Station-Identifier = <not present> Calling-Station-Identifier = <not present> Client-Friendly-Name = ASA5510 Client-IP-Address = 10.1.1.1 NAS-Port-Type = Virtual NAS-Port = 7 Proxy-Policy-Name = Use Windows authentication for all users Authentication-Provider = Windows Authentication-Server = <undetermined> Policy-Name = VPN Authentication Authentication-Type = PAP EAP-Type = <undetermined> Reason-Code = 66 Reason = The user attempted to use an authentication method that is not enabled on the matching remote access policy. My assumption is that the ASA is using PAP authentication, instead of MS-CHAP v2; the credentials are confirmed, the proper Remote Access Policy is being used, but this policy is set to only allow MS-CHAP2. What do we need to do on the ASA to make it us MS-CHAP v2? In the ADSM GUI The "Microsoft CHAP v2 compatible" tickbox is enabled, but I don't know what this corresponds to in the config.

• Why am I getting Network error: 403 Forbidden in firebug for files I am not trying to access?

  - by moomoochoo

  QUESTIONs I'd like to know why I am getting Network error: 403 Forbidden in firebug for files that I am not trying to access? is it likely to cause any serious problems on the webserver? how to fix it. Why is my browser trying to access those files in the error message? DETAILS I’m using wampserver 2.2 to access a folder via the browser. The browser is on the same computer as the server. The computer is running windows 7 ultimate. When I view a web folder via my browser hXXp://localhost/folder I can see the folder contents ok but in firebug I get Network error: 403 Forbidden I’m not deliberately trying to access those files in the error msgs. You will notice they are in a completely different folder to the one I am looking at. I check the apache_error.log and see [Wed Sep 26 00:05:10 2012] [error] [client 127.0.0.1] client denied by server configuration: C:/apache2, referer: hxxp://localhost/folder/ Wampserver 2.2 is installed on D drive.

• Performance analytics via DBMS "plugins", or other solution

  - by Polynomial

  I'm working on a systems monitoring product that currently focuses on performance at the system level. We're expanding out to monitoring database systems. Right now we can fetch simple performance information from a selection of DBMS, like connection count, disk IO rates, lock wait times, etc. However, we'd really like a way to measure the execution time of every query going into a DBMS, without requiring the client to implement monitoring in their application code. Some potential solutions might be: Some sort of proxy that sits between client and server. SSL might be an issue here, plus it requires us to reverse engineer and implement the network protocol for each DBMS. Plugin for each DBMS system that automatically records performance information when a query comes in. Other problems include "anonymising" the SQL, i.e. taking something like SELECT * FROM products WHERE price > 20 AND name LIKE "%disk%" and producing SELECT * FROM products WHERE price > ? AND name LIKE "%?%", though this shouldn't be too difficult with some clever parsing and regex. We're mainly focusing on: MySQL MSSQL Oracle Redis mongodb memcached Are there any plugin-style mechanisms we can utilise for any of these? Or is there a simpler solution?

• Windows 2008 Terminal Services "Easy Print" and Matrix Printers

  - by Cesar87

  Server: Windows 2008 Server Standard SP2 with "Terminal Services" role Clients: Windows XP SP3 + .NET 3.5 Framework SP1 + Remote Desktop Client 7.0 We are using "Easy Print" feature which allows programs running on server to "see" printers installed on client machines. Everything works fine, EXCEPT when we send a text-only output to a dot-matrix printer. In this case, the printer only outputs a blank page. At first, we had problems with the error "Windows Presentation Foundation Terminal Server Print W has encountered a problem and needs to close." but this was fixed by replacing TsWpfWrp.exe with the one from Vista SP1 as suggested here. But now, we only get a blank page! Every other (graphical) document we sent to printer works 100%. We also tried to use the "Generic text-only" driver, but the result is same. Now we are trying to change parameters like print processor on "advanced" tab from printer driver to see if something happen. But this is just guessing and we really don't know what to try anymore. The problem appears to be on Easy Print driver, but we found almost no resources about it. Any tips are welcome.

• LDAP authentication issue with Kerio Connect

  - by djk

  We have Kerio Connect (mail server) running on a Windows Server 2003 server on a domain. In the webmail client, users are able to change their domain password. This functionality used to work fine until a user tried to change their password a few days ago, when every password they'd try would result in the webmail client claiming their password was "invalid". I spoke to Kerio about this and they claim that this error is returned by the domain controller, which supports my initial investigations. The error that the DC is logging when an attempt is made to change the password is this: "80090308: LdapErr: DSID-0C090334, comment: AcceptSecurityContext error, data 52e, vece" The "data 52e" part indicates that this is an "invalid credentials" error. I don't see how this can be as I've tried (in the Kerio Connect configuration) various accounts that have privileges to modify accounts, including my own as I am a domain admin. I have ran 'dcdiag' (all tests) on the DC and it came back passing every single one of them. I've searched high and low for an answer to this and came up empty. Does anyone have any idea why this may have suddenly started happening? Thanks! Edit: I should mention that the passwords we are changing to do comply with the complexity policy.

• How to ask memcached auth connection by sasl and pam?

  - by user199216

  I use memcached in a untrust network, so I try to use sasl and pam to auth connection to memcached. I installed sasl and pam module, compiled and installed memcached with sasl enabled. Also I created db and table for pam user. I run: $ sudo testsaslauthd -u tester -p abc123 -s /etc/pam.d/memcached 0: OK "Success." where the tester and abc123 is the authed user in db, which I inserted. But my python script cannot be authed, always authentication failed returned. It seems it dose not use pam to authentication, still use sasldb, because when I add user by: $ sudo saslpasswd2 -a memcached -c tester and input password: abc123, It can passed. Python script: client = bmemcached.Client(('localhost:11211'), 'tester', 'abc123') and error: bmemcached.exceptions.MemcachedException: Code: 32 Message: Auth failure. memcached log: authenticated() in cmd 0x21 is true mech: ``PLAIN'' with 14 bytes of data SASL (severity 2): Password verification failed sasl result code: -20 Unknown sasl response: -20 >30 Writing an error: Auth failure. >30 Writing bin response: no auth log found in: /var/log/auth.log Configurations: vi /etc/default/saslauthd MECHANISMS="pam" vi /etc/pam.d/memcached auth sufficient pam_mysql.so user=sasl passwd=abc123 host=localhost db=sasldb table=sasl_user usercolumn=user_name passwdcolumn=password crypt=0 sqllog=1 verbose=1 account required pam_mysql.so user=sasl passwd=abc123 host=localhost db=sasldb table=sasl_user usercolumn=user_name passwdcolumn=password crypt=0 sqllog=1 verbose=1 vi /etc/sasl2/memcached.conf pwcheck_method: saslauthd Do I make my question clear, english is not my native language, sorry!

• Is there a good Lotus Notes open-source alternative?

  - by Ben S

  At my work we use Lotus Notes 6.5 for our email, meeting scheduling and instant messaging. I can't stand the horrible UI, buggy meeting scheduling and overall '90s feel when using it and would love to replace it with open-source alternatives. So far I've been able to setup Thunderbird for email, and I should also be able to configure pidgin to do IM, but I can't find any replacement for the meeting scheduling. I need to be able to receive meeting requests and respond to them. I've looked around trying to get the Thunderbird plugin Lightning to manage the scheduling, but everything I've read so far requires me to export .ics files from Lotus Notes or otherwise keep Lotus Notes around for day-to-day activities. I've also looked into using Evolution as the client, but I found even less information for it than I did for Thunderbird. How can I easily send, receive and respond to Lotus Notes meetings using an open-source alternative? Alternatively, if there exists a full drop-in replacement to Lotus Notes I would also consider it. Note: My desktop at work is a Windows XP machine, though I wouldn't be opposed to a solution requiring cygwin at this point. Edit: I have no power over the server. I only want a compatible client.

• Replacing DropBox with: Amazon S3 + SSL + GPG/TrueCrypt + Mounting on OSX ??

  - by Matt Rogish

  So, right now we're using DropBox to share various data files around between approximately 10 Mac OS X systems. However, we already have an S3 account and everyone on the lowest DropBox plan of $10/mo seems too expensive. We'd like to avoid any kind of local storage (share a disk on a desktop or something) since we're a geographically distributed team). So, I am contemplating something that would allow us to replace DropBox with our own home-grown solution. We are all fairly technical people and/or smart enough to follow some steps, so if it's not as "user friendly" as DropBox we're all comfortable with that. There are plenty of docs out there that have bits and pieces of what I want but some of the tools don't seem to fit the requirements: Transport security via SSL to the bucket Encryption of bucket contents Bi-directional syncing Most of the scripts I can find on the internet use "duplicity" which appears to fail #1 (it doesn't look like duplicity supports SSL to S3 - the docs don't state but the protocol looks plain old http http://www.nongnu.org/duplicity/duplicity.1.html#sect6 ) Many scripts use gpg to encrypt files. This seems like it could work, however I have to make sure that each OSX client is able to use the same key to encrypt and decrypt files (key management is left to me to manage). FTP and other client-based apps don't seem to support this at all. Finally, most of the scripts use one-way replication, e.g. using Amazon S3 as a simple backup store. As we'd be using Amazon S3 as the "repository" they fail this one. Whew. So, I'd love a single tool that does this but after an exhaustive search I don't think one exists. In my mind, the magical tool would be some combination of TrueCrypt and rsync. I'd be happy just knowing which tools out there can fulfill my 3 requirements, after that I can stitch together the rest. Any thoughts? THANKS!

• WebDav rename fails on an Apache mod_dav install behind NginX

  - by The Daemons Advocate

  I'm trying to solve a problem with renaming files over WebDav. Our stack consists of a single machine, serving content through Nginx, Varnish and Apache. When you try to rename a file, the operation fails with the stack that we're currently using. To connect to WebDav, a client program must: Connect over https://host:443 to NginX NginX unwraps and forwards the request to a Varnish server on http://localhost:81 Varnish forwards the request to Apache on http://localhost:82, which offers a session via mod_dav Here's an example of a failed rename: $ cadaver https://webdav.domain/ Authentication required for Webdav on server `webdav.domain': Username: user Password: dav:/> cd sandbox dav:/sandbox/> mkdir test Creating `test': succeeded. dav:/sandbox/> ls Listing collection `/sandbox/': succeeded. Coll: test 0 Mar 12 16:00 dav:/sandbox/> move test newtest Moving `/sandbox/test' to `/sandbox/newtest': redirect to http://webdav.domain/sandbox/test/ dav:/sandbox/> ls Listing collection `/sandbox/': succeeded. Coll: test 0 Mar 12 16:00 For more feedback, the WebDrive windows client logged an error 502 (Bad Gateway) and 303 (?) on the rename operation. The extended logs gave this information: Destination URI refers to different scheme or port (https://hostname:443) (want: http://hostname:82). Some other Restrictions: Investigations into NginX's Webdav modules show that it doesn't really fit our needs, and forwarding webdav traffic to Apache isn't an option because we don't want to enable Apache SSL. Are there any ways to trick mod_dav to forward to another host? I'm open to ideas :).

• Server 2008 R2 Dns Lockup

  - by Richard Maynard

  Hi, We've deployed our first 2008 R2 server on a client site which has replaced their existing 2003 DC. This server provides DNS resolution services to all client machines on that site for general internet usage. Since using the 2008 R2 DNS services we have noticed every couple of days the DNS server starts timing out when requests to certain sites are made (google is the only example I can provide at this time although it seems to be larger sites with problems rather than small - CDN compatiblity issue?). When you restart the DNS Server service then resolution returns to normal... just only for a day or so. Is anybody aware of any significant changes to the DNS server architecture or configuration out of the box in R2 that may explain this intermittent behaviour? I have already tried the fix listed here to no avail: http://weblogs.asp.net/owscott/archive/2009/09/15/windows-server-2008-r2-dns-issues.aspx The following PS command prompt info illustrates the issue: PS C:\Users\Administrator.UK> nslookup Default Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 > www.google.com Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 Non-authoritative answer: Name: www.l.google.com Addresses: 66.102.9.99 66.102.9.104 66.102.9.105 66.102.9.103 66.102.9.147 Aliases: www.google.com > www.google.co.uk Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 * s8209001.uk.kingdomfaith.com can't find www.google.co.uk: Server failed Thanks in advance.

• apache2 VirtualHost in Mac OS X home directory

  - by aaron

  I am running Macports apache2 on Mac OS X 10.5. Whenever I configure a virtual host in the default folder, it works, however when I configure the virtual host in my home directory I get a "403 Forbidden" error. How do I configure a vhost in my home directory? Here is the configuration that yields "403 Forbidden" when I access "devel.mysite.com": /opt/local/apache2/conf/extra/httpd-vhosts.conf: DocumentRoot "/opt/local/apache2/htdocs" ServerName * #CustomLog "" common <VirtualHost *:80> #DocumentRoot "/opt/local/apache2/htdocs/mysite" DocumentRoot "/Users/myuser/Sites/mysite" ServerName devel.mysite.com </VirtualHost> The error message in /opt/local/apache2/logs/devel.mysite.com-error_log: [Sat Apr 17 19:54:49 2010] [error] [client 127.0.0.1] client denied by server configuration: /Users/myuser/Sites/mysite/ When I uncomment the line to make DocumentRoot in /opt/local/apache2/htdocs/mysite, it works: DocumentRoot "/opt/local/apache2/htdocs" ServerName * #CustomLog "" common <VirtualHost *:80> DocumentRoot "/opt/local/apache2/htdocs/mysite" #DocumentRoot "/Users/myuser/Sites" ServerName devel.mysite.com </VirtualHost> I get no errors or warnings when I start apache, and the only thing that is logged on startup is this (in /opt/local/apache/logs/error_log): [Sat Apr 17 19:56:29 2010] [notice] Digest: generating secret for digest authentication ...

• Problems configuring an SSH tunnel to a Nexentastor appliance for use with headless Crashplan

  - by Rob Smallshire

  Problem I am attempting to configure an SSH tunnel to a NexentaStor appliance from either a Windows or Linux computer so that I can connect a Crashplan Desktop GUI to a headless Crashplan server running on the Nexenta box, according to these instructions on the Crashplan support site: Connect to a Headless CrashPlan Desktop. So far, I've failed to get a working SSH tunnel from from either either a Windows client (using Putty) or a Linux client (using command line SSH). I'm fairly sure the problem is at the receiving end with NexentaStor. A blog article - CrashPlan for Backup on Nexenta - indicates that it could be made to work only after "after enabling TCP forwarding in Nexenta in /etc/ssh/sshd_config" - although I'm not sure how to go about that or specifically what I need to do. Things I have tried Ensuring the Crashplan server on the Nexenta box is listening on port 4243 $ netstat -na | grep LISTEN | grep 42 127.0.0.1.4243 *.* 0 0 131072 0 LISTEN *.4242 *.* 0 0 65928 0 LISTEN Establishing a tunnel from a Linux host: $ ssh -L 4200:localhost:4243 admin:10.0.0.56 and then, from another terminal on the Linux host, using telnet to verify the tunnel: $ telnet localhost 4200 Trying ::1... Connected to localhost. Escape character is #^]'. with nothing more, although the Crashplan server should respond with something. From Windows, using PuTTY have followed the instructions on the Crashplan support site to establish an equivalent tunnel, but then telnet on Windows gives me no response at all and the Crashplan GUI can't connect either. The PuTTY log for the tunnelled connection shows reasonable output: ... 2011-11-18 21:09:57 Opened channel for session 2011-11-18 21:09:57 Local port 4200 forwarding to localhost:4243 2011-11-18 21:09:57 Allocated pty (ospeed 38400bps, ispeed 38400bps) 2011-11-18 21:09:57 Started a shell/command 2011-11-18 21:10:09 Opening forwarded connection to localhost:4243 but the telnet localhost 4200 command from Windows does nothing at all - it just waits with a blank terminal. On the NexentaStor server I've examined the /etc/ssh/sshd_config file and everything seems 'normal' - and I've commented out the ListenAddress entries to ensure that I'm listening on all interfaces. How can I establish a tunnel, and how can I verify that it is working?

• ASP.Net application can no longer write to DB after having run out of disk space

  - by remi.despres-smyth

  I'm a software developer troubleshooting a sticky problem on a client's production server, and I've got a bit of a problem. They have a virtual server running Windows Server 2008, SQL Server 2008 R1 and IIS7. It was provisioned with two partitions: one that has the OS (~15 Gig), and the other has IIS' web sites (another ~15 Gig). My application that's running this server has been running perfectly well, up until about an hour ago, when it started throwing System.IO.IOException: "There is not enough space on disk". As soon as my client notified me, I cleared up some space on C:\, emptied the recycle bin, and restarted SQL Server and IIS. The web server came back up and the application was running, but it no longer saves information to the database. No error message is coming up, the application can get information out of the DB, but it can no longer save data back to it. I rebooted the server, to no effect. I spoke with a sys admin at the hosting company, and he says SQL Server appears to have come up fine and the database is not in read-only mode. I confirmed that, as I can add records to tables from SQL Server Management Studio. I looked at the event log immediately after trying to save an edited record in the app, and no new events appear in there that I can tell. I'm assuming this is related to having run out of space, as it was all working fine prior to that, but I'm at a bit of a loss as to what exactly needs a kick in the pants to get going again. Can anyone help me out? What the heck is going on here?

• Can connect through Watchguard mobile VPN, but can't ping or access network drives

  - by johnnyb10

  We're having any issue in which some of our employess can no longer connect to our network drives when out of the office. We use Watchguard Mobile VPN (we have a Watchguard Firebox firewall) and the users are able to connect. That is, their status in the the VPN client says "Connected" and they have the correct IP address listed as the VPN Endpoint. The problem is, when they try to map drives, or even ping the IP address of a server on our network, it fails. Last week, we temporarily switched one of our Comcast modems to our backup DSL modem because the Comcast was accidentally shut off by Comcast, and the problem seemed to start around then. We've since switched back and the problem persists, so that doesn't seem to have been it (which makes sense). But we also made other changes at the time that might have thrown something off, although we feel like we've checked them all. Plus, some people can successfully connect to network drives through the VPN. Can someone please suggest some steps to help troubleshoot? We've checked the policies on our Watchguard box, and they seem fine. We've looked at the settings on the Mobile VPN client, but nothing seems like a probable cause. Thanks.

• How does a web server/the http protocol handle version control and compression?

  - by Sune Rasmussen

  When a client browser requests a file from the web server, I know that some kind of check is performed, because the files needed to serve the web page may already be cached by the web browser. So, if a file exists in the cache, no files are sent. But if the file on the server has changed since the file was cached in the browser, the file is sent and updated anyhow. Then, if you have compression like gzipping enabled on the server, the files that are to be provided to the client must be gzipped on the way, requiring some amount of server side processing. But how is this managed? The logical approach seems to me, that the web server should have a cache as well, containing the newest version of all files that have been requested within a certain time span, thus a compressed version of these files, so that compression would not have to be done each time a files is requested. And also, how are files eventually requested? Does the browser ask for files, each time it encounters one in the HTML code and the specific file is not stored in the local cache, or does it sum all the files that are needed up and ask for the whole bunch at the same time? But that's only guessing from a programming point of view, and I don't really know. If the answers are very different among web server systems, I'm primarily interested in Apache, but other answers are appreciated, too.

• snmpd dead but subsys locked

  - by Hina NMS

  Hi folks I have an NMS and a Client machine. I want the client to send traps to the NMS. I have been configuring the snmpd.conf file testing if i disable a process do i receive an alert or not. For the changes to reflect that were made in the conf file i restarted the snmpd daemon each time. The testing was going fine. All of a sudden when i restarted snmpd i recieved the error msg "snmpd dead but subsys locked". I googled for answer as to what it actually meant and found out that when a service is started a logfile is created in the /var/lock/subsys. Sometimes if the service is not stopped properly or whatever the logfile remains created. Though i started/stopped the snmpd service properly it didnt go away so i removed the file manually (via rm cmd). when i checked the status the error "snmpd dead but subsys locked" was gone. On my NMS i recieved the alert of snmpd coldstart. i started the snmpd service everything goes fine! BUT after 5 mins again i recieve the same error message and this keeps on happening..what do i need to do now?

• What might cause https failure when not specifying SSL protocol?

  - by user35042

  I have a VBScript program that retrieves a web page from a server not under my control. The URL looks something like https://someserver.xxx/index.html. I use this code to create the object that does the page getting: Set objWinHttp = CreateObject("WinHttp.WinHttpRequest.5.1") When I wrote my program it had no problem retrieving this page. Recently, the web server serving this page went through an upgrade. Now my program can no longer fetch the page. Some clues: Clue 1. I can fetch the web page if I use a browser (I tried Firefox, IE, and Chrome). Clue 2. The VBScript code yields this error: The message received was unexpected or badly formatted. Clue 3. I can fetch the web page from the command line in certain cases but not in others: curl --sslv3 -v -k 'https://someserver.xxx/index.html' # WORKS! curl --sslv2 -v -k 'https://someserver.xxx/index.html' # WORKS! curl -v -k 'https://someserver.xxx/index.html' # FAILS curl --tlsv1 -v -k 'https://someserver.xxx/index.html' # FAILS In the case where I do not specify a protocol I get this error: * SSLv3, TLS handshake, Client hello (1): * error:14077417:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert illegal parameter * Closing connection #0 In the case where I specify --tlsv1 I get this error: * SSLv3, TLS handshake, Client hello (1): * SSLv3, TLS alert, Server hello (2): * error:14094417:SSL routines:SSL3_READ_BYTES:sslv3 alert illegal parameter * Closing connection #0 A. Does anyone have any suggestions or ideas on what might be going on at the web server end (I am unable to talk to the admins of the web server to find out what they changed). B. Is there a way I can change my VBScript code to work around this issue? Can the SSL version be forced?
