Re: Webmin/Usermin & proxies
by Matthew 05 Apr '07

05 Apr '07

Progress! With a <Proxy> block to Allow from all, I get 500 rather than 403 ;-) It looks like an Apache issue still, although I can't be sure. I saw a neat trick somewhere about trapping errors in your proxy (so that you can serve a different page if your backend application server is down); maybe I can find the instructions again and use that to work out where the fault is. Curiously, I have a set of other virtual servers that proxy heavy requests to another instance of Apache and I don't recall having declared a <Proxy> with Allow for them. They use mod_rewrite instead of ProxyPass, but I get the same results either way when passing requests to Usermin. I'll try some more tweaking; thanks for the help. >> I believe you need to add something like >> >> <Proxy *> >> Order deny,allow >> Allow from all >> </Proxy> >> >> To allow access to the proxy. > > I've just been reliably informed (by Brett on IRC) that <Proxy *> is > not a good idea and that you should bind it to a particular ip:port > > So.. > > <Proxy ip:port> > Order deny,allow > Allow from all > </Proxy>

Use of () in 'test' (or [ ])
by Chris G 05 Apr '07

05 Apr '07

I want to group some logic in a test in a bash script. I.e. I am trying to write something like:- if [ this -a (that -o theOther) ] but bash always complains about 'syntax error'. I have reduced the code to the trivial:- home$ if [ ( true ) ]; then but still get the syntax error. According to the man page for test the format is:- ( EXPRESSION ) EXPRESSION is true I *think* that is trying to tell me that I can use () to group parts of what is inside the []. However, as I said, it refuses to work as I expected. I have tried all combinations of spaces etc. either side of the () but it still just gives a syntax error. Is this just a case where the () are punctuation in the man page rather than real () to use in the expression? Or am I doing something obvious wrong? (probably!). I know I *could* rely on precedence in the tests to get the result I want but it's much easier to write and to understand using () for grouping the logic. -- Chris Green

Linux 'split' OK; Windows 'join' ???
by ted.harding＠nessie.mcc.ac.uk 04 Apr '07

Hi Folks, A bit one foot in each camp this time. I have a large file to transfer from a Linux machine to a Win98 machine, and for practical reasons only able to use floppies. On Linux, split -C 1m nicely produces 1MB size chunks that fit on floppies and can then be read into the win98 machine. Done. So far so good. But -- what's the way to paste the bits together again on Windows? On Linux there's a choice of ways! But Windows??

Webmin/Usermin & proxies
by Matthew 04 Apr '07

04 Apr '07

This may be a bit of a long shot but is anyone familiar with Webmin or Usermin, and has anyone tried serving either from behind a proxy? I'd like to offer minimal Usermin to mail users and the like, but I'd like to proxy it through Apache to keep it in the same namespace (and on the same port) as the rest of my HTTPS applications. The most likely culprits for an Apache config issue are the proxy statements: ProxyPass / https://localhost:20000/ ProxyPassReverse / https://localhost:20000/ Usermin works fine as a direct request on port 20000, but the proxy returns 403: Forbidden. The Apache logs show the 403, but I think it was originated by Usermin and I can't find anything useful in its logs (it's not even producing one of the log files). Turning off Usermin's SSL doesn't make any difference, nor does using IP or FQDN instead of 'localhost' in the proxy directives. Usermin should be accepting connections from any IP, so I think it dislikes something about the proxying. I barely understand what mod_proxy is up to at the best of times. Anyone got any suggestions? Anything else I could look at? Thanks, Matthew

How to put newlines or returns in a shell variable *and* check they're there?
by Chris G 03 Apr '07

03 Apr '07

I want to set a variable in a shell (bash) script with a newline as one of the characters. First question, how do you do it? Second question, how do you prove it's there once you've done it? I *think* there are several fairly obvious ways of doing it, e.g. things like:- export fred="abcde ghijk" However the problem is that using 'echo' to see what you have done is totally useless as echo does so many clever things under the cover that you don't get to see what's actually in the variable at all. If you do the above and then say "echo $fred" you just get:- abcde ghijk Harrumph! *Surely* there's some way of saying "show me what's really in this variable/string" (a bit like 'od' but for variables). -- Chris Green

bt home hub - how to setup ubuntu to recognise modem
by elc＠freeola.net 02 Apr '07

02 Apr '07

JT I stand advised re your first para. Currently connected to my main machine via usb is an epson 680 printer, a wireless optical mouse, and of course the bt wireless home hub . Also on occasion I plug in and use Integral flash drive memory sticks. All of these are working well in windows and linux, with the exception that is, of the home hub in linux. Eric Eric, As an asside, please post replys to main(a)lists.alug.org.uk because that way other people can step in with advice... Ok, what we need to work out is whether or not your USB is actually working. Now this might be simple as turning it on - but are you aware of any other USB devices working ok in linux (for example, your USB keyboard or USB mouse or USB printer or anything (any one of these working suggests that USB hotplug stuff will be enabled and thats all ok).. If thats all ok, then it might be as simple as configuring it as a USB network card, to which I would have to pass you over to someone else on the list for that... As for wireless network cards (usb ones) not all of them are erm "compatible" with linux or are very hard to configure where some are very much so (due to openness of hardware spec and manufacturers niceness towards open source community) so someone on the list can suggest good ones that will work in Linux and Windows.

Any NFS experts out there
by Charles Garcia-Tobin 02 Apr '07

02 Apr '07

Hi there I'm trying to set up my NFS mount options so that if my server goes down, the file access fails as immediately as possible. Instead it seems to hang forever. Currently I have the following: rw,nolock,soft,intr,timeou=1,retrans=1 With these option I can get the mount either fail or succeed instantly which is great. But if the server goes down, and the client tries to access a file, or cd into the mount, it just hangs forever. Ideally it would also fail quickly. I am mounting via autofs files from a server that is not always turned on. Global warming and big electric bill!! Any ideas welcome Cheers Charles
