The real problem is likely within Tcl, but I do not have the time to invest in tracking it down. The patches do fix the problem. The bug has been reported to the expect folks, but I've not seen any reply or progress on it. Just use the hacks, err patches. For linux, use expect-hack1 , which makes the file descriptors non-blocking. This is the original patch and as expect versions advance, this may apply with some fuzz. For Solaris, expect-hack2 , which uses poll 2 to test the file descriptors for waiting data.
Making the file descriptors non-blocking caused streams problems for us under Solaris 2. This patch ought to work just fine for Linux as well. For FreeBSD, it seems that this problem, or similar, may have recently appeared with the expect-devel port 5. What we've seen is that it does not hang but otherwise resembles this same bug.
The non-devel expect port is still 5. One more bit on Solaris. If you have experienced rancid or more precisely, telnet hanging on a solaris 2. There may be more recent versions of these patches and they are likely included with 2. The version of Tcl that is there is the mate to this Expect. They are there merely for convenience, since we get some folks not familiar with C or patching. Some folks have tried to argue with me about these patches.
The fact is that I just don't care to argue about it. You can use the patches or not, but do not ask for help and refuse to use them. Man pages on-line. Libraries 3 : rancid 3. File formats 5 : cloginrc 5 lg. Version-specific information. This means that some combination of sudo apt-get update , sudo apt-get upgrade , sudo apt-get dist-upgrade , and sudo apt-get autoremove should have been recently run. Please understand what the commands do before blindly running them as any system update has the potential to render a system inoperable.
Groups can be based on any criteria you wish. So if you've got one physical location you could create "router", "firewall", and "switch" groups, or, in larger environments with multiple physical locations, group names such as "Los Angeles", "San Francisco", and "New York" may be a better choice.
For this example we'll create groups based on the geographical location of devices. So let's create a group for each of these locations. Even though it's a blank file, it's good practice to start by making a backup copy of the original rancid. Since Ubuntu use sendmail by default, this can be accomplished by running This provides a way to track changes over time as well as provides you with a bit of disaster recovery.
Since everything went smoothly and you received an e-mail and the directories was populated with configuration files, you probably want RANCID to run automatically. Cron will aid you with this. Configure cron with the rancid-user. Have been working in the IT business since and have had network and security as field of focus since Hi, I was looking for information for configuration of sending one email a day, I read your configuration file but do not understand how effected this configuration?
Greetings and thank you. The mail job is triggered within rancid-run. The following cron job runs at every day. This has bee really a great article. Thanks for sharing. The whole purpose of configuring it was to use rancid. I can successfully execute the CGIform script but when I try to ping it give me error. Can you please help.
