Weird DNS problem on my Unbuntu box. I can ping, curl the homepage, but the curl upload command fails. See trace below:

    <p>It's showtime in a terminal near you! Put on your best colours,
        resize to 80 columns, and let your fingers fly!</p>

    <p>Termshows are purely text based. This makes them ideal for demoing
        instructions (as the user can copy-paste), making fail-safe
        "live-coding" sessions (plain text is very scalable), and sharing all
        your l33t terminal hacks.</p>

    <p>Installation instructions have been showtermed for your enjoyment :)</p>

    <h2 id="install">Install</h2>

    <p>There are two ways to install showterm. The recommended way is to use ruby:</p>

    <ul>
        <li>gem install showterm</li>
    </ul>

    <p>This works for all Mac users, and Linux users with ruby configured correctly.</p>

    <p>If you are a Linux user who does not have ruby configured correctly, you can
    install showterm with:</p>

    <ul>
        <li>curl showterm.io/showterm &gt; ~/bin/showterm</li>
        <li>chmod +x ~/bin/showterm</li>
    </ul>

    <h2 id="use">Use</h2>

    <p>If you have installed showterm, you can just run it:</p>

    <ul>
        <li>showterm [program to run]</li>
    </ul>

    <p>If [program to run] is omitted it defaults to your shell (usually bash)</p>

    <p>If you have not installed showterm, you can run the standalone version:</p>

    <ul>
        <li>bash &lt;(curl record.showterm.io)</li>
    </ul>

    <h2 id="link">Linking</h2>

    <p>Each termshow gets its own link. You can add hash-fragments to customize playback,</p>

    <ul>
        <li><a href="http://showterm.io/7b5f8d42ba021511e627e">http://showterm.io/7b5f8d42ba021511e627e#slow</a>
            — realtime</li>
        <li><a href="http://showterm.io/7b5f8d42ba021511e627e#fast">http://showterm.io/7b5f8d42ba021511e627e#fast</a>
            — double-speed</li>
        <li><a href="http://showterm.io/7b5f8d42ba021511e627e#stop">http://showterm.io/7b5f8d42ba021511e627e#stop</a>
            — stopped</li>
    </ul>
    <p>access the site over https,</p>
    <ul>
        <li><a href="https://showterm.io/7b5f8d42ba021511e627e">https://showterm.io/7b5f8d42ba021511e627e</a>
        — secure!</li>
    </ul>

    <p>and embed termshows in your own website with iframes.</p>

    <div style="border: 1px solid #444; font-size: small; padding: 10px; width: 642px">
        &lt;iframe src="http://showterm.io/7b5f8d42ba021511e627e" width="640" height="480">&lt;/iframe>

I got this error too(install via curl showterm.io/showterm > ~/bin/showterm), but the upload is done already. See https://github.com/ConradIrwin/showterm/issues/31 also.

Ping @ConradIrwin :smile:

Had the same confusing error message. Adding the --silent flag to the curl command "solves" the "problem".

No freaking idea though what causes the problem. The answer from the showterm.io server looks perfectly normal.

joomlagate commented 8 years ago

I got the same error. I thought my recording was NOT uploaded until I read this thread. Well, now I know in fact the recording was already uploaded. But I still got this error:

[root@localhost ~]# exit exit Uploading... http://showterm.io/4938e5a0dfd1c8782cb04curl: (6) Could not resolve host: ; Name or service not known Uploading failed, but don't worry! Your work is safe. You can try uploading again with: curl showterm.io/scripts --data-urlencode cols=113 --data-urlencode lines=22 --data-urlencode scriptfile@/tmp/Bqb7Y.script --data-urlencode timingfile@/tmp/6LKEr.timing secret@/root/.showterm [root@localhost ~]#

I too have this issue. Using Arch Linux, for what that's worth.

ConradIrwin commented 8 years ago

It looks like there's a stray semi-colon "Could not resolve host: ;". Can someone find it and send a PR to remove it?

victorbrca commented 8 years ago

I think the issue is because the secret is being passed on as an argument without being giving it a curl flag.

Try changing the script from: if curl --fail "$url" --data-urlencode "cols=$cols" --data-urlencode "lines=$lines" --data-urlencode "scriptfile@$scriptfile" --data-urlencode "timingfile@$timingfile" "secret@$HOME/.showterm"

To: if curl --fail "$url" --data-urlencode "cols=$cols" --data-urlencode "lines=$lines" --data-urlencode "scriptfile@$scriptfile" --data-urlencode "timingfile@$timingfile" --data-urlencode "secret@$HOME/.showterm"

And that should fix it.
