The problem is best explained in this e-mail. To correct this, we worked out the following patches, which amount to making the socket or file descriptor non-blocking. OK, these are not so much patches, as they are hacks. 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. To prepare the CVS database you have to run the command rancid-cvs as the rancid user which was created by the install. This needs to be done each time you add a new group. The router. Add devices to the group as per below.
Credentials to access the devices is stored in the. Edit the file and add these lines:. To login with the username rancid and password s3ctetp ssw0rd to all devices. The autoenable line tells RANCID that the devices are configured to place the rancid user in enabled mode directly after login. It is also possible to configure the.
Or use a different username and password against some of your devices such as:. Once the authentication has been setup you can test to see that it works. Using the rancid user sudo -i -u rancid you can try to login to one of the devices.
You might want to add these to your path. For example hlogin is for HP devices and flogin is for Foundry. This will schedule a run each hour and notify the members of the respective group each time any of the devices change.
You can of course set it to run how often you like, for some environments once every night might be enough. Another option is to have separate schedules for each group. If rules are added or removed constantly in your firewalls but your switches rarely change you might want to have different schedules for those groups. Once you have executed rancid-run or it has been run by cron your device configurations will be stored in the configs directory for each group.
Examining the output you can see that there are three revisions of sth-asw-2 so far.
