Regards, Sanjeev Posted by admin (Graham Ellis), 1 April 2006 The extra characters are a terminal control sequence that's sent out by your remote host to provide formatting. If you set the terminal type for your session to DUMB, you should be able to prevent the problem. Do so via the login's .bashrc file or via an export command that's a part of your sequence if you're using the bash shell ... the commands / files vary a bit for other shells.Sanjeev, welcome to Opentalk. You write "Please help me out by gving a fast reply" I have a target of making technical comment (at least) on 90% of questions within 24 hours, and I always get back quicker if I can. I prioritise questions raised by people who give (i.e. help answering questions) as well as take, and questions raised by people I have trained (for whom the service was created in the first place). If you are not in one of these groups and require a faster support service, you can buy it; have a look here for example - "Entry P4" lists a contract at $2500 per annum with 24 hour emergency support available on an additional time and materials basis. However, that is not something I can provide. This page is a thread posted to the opentalk forum
