[rancid] Ubuntu 8.04 LTS, rancid, and Expect 5.43.0-14

[Chris Gauthier]

Hi all,

 

In trying to track down what was ultimately a typing problem in front of
the keyboard, I've developed a set of steps to include the expect patch
in Ubuntu 8.04 LTS (Server Ed)'s expect package.  I've also tried to
submit this to the maintainer of the package, so we shall see what
happens. 

 

A handy page I referred to for compiling packages:

http://www.cyberciti.biz/faq/rebuilding-ubuntu-debian-linux-binary-packa
ge/

 

Here are the steps:

 

1)      paco at test:~$ sudo apt-get install build-essential fakeroot
dpkg-dev

2)      paco at test:~$ cd /usr/src/

3)      paco at test:/usr/src$ sudo apt-get source expect

4)      paco at test:/usr/src$ cd expect-5.43.0/

5)      paco at test:/usr/src/expect-5.43.0$ sudo patch <
~/expect-rancid-ubuntu804lts.patch

a.       Patch contents:

--- exp_chan.c.bak      2008-08-29 11:46:51.000000000 -0700

+++ exp_chan.c  2008-08-29 12:14:28.000000000 -0700

+       fcntl(esPtr->fdin, F_SETFL, O_NONBLOCK); /* patched line for
rancid */

     bytesRead = read(esPtr->fdin, buf, (size_t) toRead);

     /*printf("ExpInputProc: read(%d,,) =
%d\r\n",esPtr->fdin,bytesRead);*/

     if (bytesRead > -1) {

6)      paco at test:/usr/src/expect-5.43.0$ cd ..

7)      paco at test:/usr/src$ sudo apt-get build-dep expect

a.       Just say "yes" when it wants to install a ton of dependencies.
You need this for compiling.

8)      paco at test$ sudo dpkg-buildpackage -rfakeroot -b

a.       This step could take a while, depending on your processor speed
and memory for compiling.

b.      Don't worry about the package signature errors at the end.
You're not the maintainer anyway. ;-)

9)      paco at test:/usr/src$ sudo /usr/bin/dpkg -i
expect_5.43.0-14_amd64.deb

a.       Your actual filename may differ, depending on architecture.
Adapt and move on.

Processing triggers for libc6 ...

ldconfig deferred processing now taking place

10)   That's it!  You're package is installed with a patched version of
Expect.
