i am attempting to use Rebex ftp using a shared virtual server, CloudSites from www.rackspace.com. This hosting strictly imposes medium trust restrictions. when I run the app on my development PC which runs IIS locally -no problem. Same code on the host I get the following error message. Is there something I can set or switch off to make it work. Googling this, i see this is a medium trust My application is an ASP.NET version 3.5 web based application rather than windows forms Code which fails |

Unfortunately, there are some permissions we need that are not available in medium trust. For example, one of them is Is it possible to ask rackspace to prepare a customized permission set for you and add at least Some methods (like using proxy with NLMN or Windows integrated authentication) also require permission to execute unmanaged code but if you do not call them rest of app should execute fine). unfortunately Rackspace requires that all applications conform to medium trust condtions. Can you prepare a customised version which does not sue socketpermission? If not I am unable to use this control and would kindly request a refund. Thanks

The SocketPermission means that application is allowed to communicate over network. Creating a functional FTP component without using this permission is impossible to anyone, sorry. Regarding refund - sure, no problem - each order come with a money back guarantee (30 days by default). To request a refund send us your order number to support@rebex.net.

I have the same problem, but the issue is not related to SocketPermission, which Rackspace Cloud grants. The problem is that the Rebex SFTP library demands FileIOPermission, even if I am using Streams and not file names in my API calls. Actually the Connect method fails because it requires FileIOPermission. Is it possible to have a version which does not require FileIOPermission? Here's the stack trace: why do you try reading the Assembly location? Is that for licensing purposes? It just does not work. System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Reflection.Assembly.get_Location() at cfDEPv.blAlGPZ.COzXmRZ() at cfDEPv.blAlGPZ.AiWkiLZ() at Rebex.Net.Sftp.beYqct() at Rebex.Net.Sftp.Connect(String serverName, Int32 serverPort, SshParameters parameters) at Rebex.Net.Sftp.Connect(String serverName) at Antea.ECG.NetworkProtocols.SFTP.Connect() |
