Dear brothers. one office with ADSL is using ADSL modem. interfaces are two ports for phone line in and out and RJ45 port link from which we can use internet. THat adsl is DHCP client IP with authentication of username and password. the other is broadband with static IP with which we can enter on client to use internet . I wanna use is like below side A clients<--------VPN1(ubuntu box)---------VPN2(UBuntu)----------> side B clients the main reason is to share everything between two offices. mainly file share and local messaging. thanks <div class="gmail_quote">On Wed, Jan 27, 2010 at 8:28 AM, <<a href="mailto:ubuntu-users-request@lists.ubuntu.com">ubuntu-users-request@lists.ubuntu.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Send ubuntu-users mailing list submissions to <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> To subscribe or unsubscribe via the World Wide Web, visit <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> or, via email, send a message with subject or body 'help' to <a href="mailto:ubuntu-users-request@lists.ubuntu.com">ubuntu-users-request@lists.ubuntu.com</a> You can reach the person managing the list at <a href="mailto:ubuntu-users-owner@lists.ubuntu.com">ubuntu-users-owner@lists.ubuntu.com</a> When replying, please edit your Subject line so it is more specific than "Re: Contents of ubuntu-users digest..."

If both offices are using a router, you need access to those routers to setup routing rules. Or you have to use the Ubuntu VPN boxes as the routers. I hope you are not new to networking also. If you are new at all this, you must be prepared to spend time learning (could take a week or more) or you might be better off hiring an expert. Again, if you are using routers and they are supplied by the ISP, then you need access to those routers. ---------- Forwarded message ---------- From: Brian McKee <<a href="mailto:brian.mckee@gmail.com">brian.mckee@gmail.com</a>> To: "Ubuntu user technical support, not for general discussions" <<a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a>> Date: Tue, 26 Jan 2010 20:27:13 -0500 (EST) Subject: Re: How to monitor server availability and send alert via SMS when down <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Do anyone know how to monitor server availability and send alert via SMS when down? </blockquote> You can try to monitor the availability via cacti/nagios/zabbix.

If you say it is not > true can you *explain* please. This is the first time ever that I had to dig up the source of a program to settle an argument. I hope it will be the last time too... In the coreutils source, in ls.c, you will find the following piece of code starting on line 2818: if (err != 0) { /* Failure to stat a command line argument leads to an exit status of 2. For other files, stat failure provokes an exit status of 1. */ file_failure (command_line_arg, _("cannot access %s"), absolute_name); if (command_line_arg) return 0; f->name = xstrdup (name); cwd_n_used++; return 0; } You see, nepal? If ls can't stat an argument (like a filename with or without wildcard), it will throw an error. Statting a file means getting its properties from the filesystem. > Let me put it another way then, the command "ls" is supposed to return > a list, that is the meaning of the shortened version of the word list > (ls). I am not an idiot, nepal. I have taken AND passed an LPI exam. (Linux Professionals Institute) > The command is not supposed to make clever comments like I > cannot find what you asked for. That is not what was asked for. That's not what the source code says, and the source code is always right. Of course there is a remote possibility that you have hacked your version of ls and that you have stripped it from all error reporting, but I find that very unlikely. > Talk to > it like it is an idiot.

Again, wrong. Basic error reporting is part of normal program operation, and Linux even makes it easy by giving us not one but two outputs: out (first output) and err (second output). By default, output 1 and 2 are both printed to the console, but they can be redirected. That's why Werner's suggestion will probably be the simplest solution for Linda: just redirect the error output (second output) to something else than the console, for example to /dev/null aka the bit bucket: ls [non-existing filename] 2>/dev/null For me this thread is closed. Linda has an answer that will work (Linda, please say so if you still have problems). I'm not interested in further discussion because that does not help Linda. -- Amedee ---------- Forwarded message ---------- From: Linda <<a href="mailto:haniganwork@earthlink.net">haniganwork@earthlink.net</a>> To: "Ubuntu user technical support, not for general discussions" <<a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a>> Date: Tue, 26 Jan 2010 19:50:19 -0600 Subject: Re: ls Werner Schram wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> nepal wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> On Tuesday 26 Jan 2010 21:03:53 Linda wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Is there a way to make ls silent if there is no match?

The correct response to *ls* for a non-existent target should be an empty list. nepal. </blockquote> ls does print an error message if you provide a filter which doesn't yield a result (ls: cannot access ...: no such file or directory). I think she is refering to that. But because the error message is sent to the standard error output, you can dispose of it by using: ls [non-existing filename] 2>/dev/null Werner </blockquote> The cannot access is the message I was refering to. I was using an ls system call inside of a program. ls -1 partial-filename* it dumps the results into a file and gives the user a list to choose from. I just was hoping for a flag to silence the error message but I can redirect standard error instead.

Linux has built-in separation between normal output and error output, so programs don't have to provide special flags. The user only has to use the built-in output redirection. That will work for all programs and the programmers don't need to define extra flags. Isn't Linux great? :-) -- Amedee ---------- Forwarded message ---------- From: "Amedee Van Gasse (ub)" <<a href="mailto:amedee-ubuntu@amedee.be">amedee-ubuntu@amedee.be</a>> To: <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Date: Wed, 27 Jan 2010 02:58:01 +0100 (CET) Subject: Re: ls On Wed, January 27, 2010 02:53, Demis Cunha wrote: > Linda, > > If you write a script you could use perl for that.
