[SLUG] Thanks and next
Thanks to those who gave advice on moving a directory and leaving a symbolic link. Seems to work. As a matter of fact the whole system seems better now that the pressure is off hd6. It was over 90% full. Next. Back when I used another OS, I had a Norton Utilities program that was a rescue package using both a floppy and a zip disk. Needless to say, it came in handy. I don't believe there is anything like that for Linux, but if I was to fill a zip with 100Mb of the most important stuff, what would be the best candidates. This would be sort of a partial backup of essentials since I don't have a tape unit or a CD burner. Any ideas?

Re: [SLUG] wget with proxy authentication
How to use proxy user/passwd on wget? I didn't find it on the command line options or config file (.wgetrc). You left one out, the documentation. It has this under the heading "Proxies". Proxies Proxies are special-purpose HTTP servers designed to transfer data from remote servers to local clients. One ... Some proxy servers require authorization to enable you to use them. The authorization consists of username and password, which must be sent by Wget. As with HTTP authorization, several authentication schemes exist. For proxy authorization only the Basic authentication scheme is currently implemented. You may specify your username and password either through the proxy URL or through the command-line options. Assuming that the company's proxy is located at `proxy.srce.hr' at port 8001, a proxy URL location containing authorization data might look like this: http://hniksic:[EMAIL PROTECTED]:8001/ Alternatively, you may use the `proxy-user' and `proxy-password' options, and the equivalent `.wgetrc' settings proxy_user and proxy_passwd to set the proxy username and password. So depending on the type of authenticate you need you may be out of luck. Especially if the proxy server is MS proxy. Rodos -- [EMAIL PROTECTED] | What goes up must come down.

RE: [SLUG] [OT] repeaters hubs ##
The bonus job of a repeater is also that it can extend the network limit of 100 metres by rebroadcasting the packets onto the other network. Similar to a linux box with 2 network cards and a route between the two. The drawback is there are alot more chances of getting collisions and the delays are larger due to the retransmission.. but really you don't notice it.

Re: [SLUG] wget with proxy authentication
http://hniksic:[EMAIL PROTECTED]:8001/
Yes, thanks, but...
My username contain the '@' character (I can't change it) and wget responds
with invalid port specification or not recognized it at all. How to solve the
problem?
Go with the source gizmox.
In url.c there is the following function that does all the parsing of the
URL you enter. It determines if you have a user and password set by
looking for the literal @ character (in a function named skip_uname).
parseurl (const char *url, struct urlinfo *u, int strict)
{
/* Allow a username and password to be specified (i.e. just skip
them for now). */
if (recognizable)
l += skip_uname (url + l);
for (i = l; url[i] url[i] != ':' url[i] != '/'; i++);
So you cant have the @ anywhere else or it brakes it. A little futher on
it does the actual parsing out of the user and password.
/* Parse the username and password (if existing). */
parse_uname (url, u-user, u-passwd);
/* Decode the strings, as per RFC 1738. */
decode_string (u-host);
decode_string (u-path);
if (u-user)
decode_string (u-user);
if (u-passwd)
decode_string (u-passwd);
Now the good news is that after it has extracted out the user and password
it calles decode_string on them. This means that you can escape your
special characters and it will decode them for you,
You should therefore be able to use %40 instead of your @ character.

There isn't one - except that the word "repeater" is usually used when
referring to devices which use 10Base2 {coaxial} cable, and hub is usually
used when referring to 10BaseT {Unshielded twisted pair} cable.
Electrically they're identicle devices.

The bonus job of a repeater is also that it can extend the network limit of
100 metres by rebroadcasting the packets onto the other network. Similar to
a linux box with 2 network cards and a route between the two.
The drawback is there are alot more chances of getting collisions and the
delays are larger due to the retransmission.. but really you don't notice
it.
Absolute bollux.
You can extend your network using hubs as well - as long as you apply the
5-4-3 rule to the total segment length and number of repeaters.
As far as collisions go - there's the same chance using a hub as there is
using a repeater - which is entirely network traffic dependant. The only
devices which will reduce your level of collisions are routers
{overkill!}, and switches.

RE: [SLUG] [OT] repeaters hubs ##
I was told that the cable length limit was the longest 2 cable ends from
point to point. So if you had 30 cables plugged into a hub and the longest
cable was 80 meters and the second longest was 50 then you would have gone
over the limit length by 10 metres right??? Makes sense in a way but doesn't
make sense or may not apply to your diagram...
As it is effectively one network, you have 500 meters there from node 1 to
node 2

Not on 10BaseT, no. But it's not much [1] beyond the 100 metre limit -

It might have worked with power cables, but once the segment started to get loaded the collisions weren't being propgated fast enough so down the network went. I put a TDR onto the segment and swore never to employ that sparky again.

DaZZa Sorry, going to have to contradict you again there. That would be a repeater. Bridges segment a network at the data link later. They can be used to physically break up a network and build a forwarding table of MAC addresses such that a broadcast to a particular address will only pass through the bridge to a particular network segment if a) the destination address is known to the bridge to be on that segment or b) the bridge doesn't know where the destination is, in which case it will forward the frame on to all network segments barring the originating port. This forwarding table is dynamically built, the bridge learns new destinations as it goes and adds these MAC addresses to this forwarding table. -- Alexander Else http://cyberchrist.org -- SLUG - Sydney Linux Users Group Mailing List - http://www.slug.org.au To unsubscribe send email to [EMAIL PROTECTED] with unsubscribe in the text

So if you had 30 cables plugged into a hub and the longest cable was 80 meters and the second longest was 50 then you would have gone over the limit length by 10 metres right??? Makes sense in a way but doesn't make sense or may not apply to your diagram... As it is effectively one network, you have 500 meters there from node 1 to node 2 What's the go? You were told wrong. The maximum cable length is dependant on media type - 100 metres for 10BaseT, 185 metres for 10Base2, 500 metres for 10Base5 For 10Base2 and 10Base5, these lengths _include_ any taps or runs to connect nodes, because they are a bus type system. for 10BaseT, this length refers to the distance between any one node and its repeater/hub, or between ahy two cascaded hubs.

This makes alot more sense otherwise the worlds networks would be bl#dy damn small.. Referring specifically to 10BaseT, and nothing else... You can run a _total_ cable length, including patch leads from your network wall point, of 100 metres from hub point to NIC _for each port on the hub_. So yes - you can run 1 PC 100 metres from the hub, and another PC 100 metres from the hub, and they'll work fine.

Sorry, going to have to contradict you again there. That would be a repeater. Bridges segment a network at the data link later. They can be used to physically break up a network and build a forwarding table of MAC addresses such that a broadcast to a particular address will only pass through the bridge to a particular network segment if a) the destination address is known to the bridge to be on that segment or b) the bridge doesn't know where the destination is, in which case it will forward the frame on to all network segments barring the originating port. This forwarding table is dynamically built, the bridge learns new destinations as it goes and adds these MAC addresses to this forwarding table. And I'm going to disagree again. :-) A repeater connects similar media types, and repeats. A bridge conencts _dissimilar_ media types, and repeats. You're describing a switching farbric, using spanning tree and the like to me, not a bridge. My definition is much more old school. ;-) I've known it that way for 15 odd years, and I'm not gonna change just because somebody decides to use a funkier name. And this is _way_ off topic for here, so all else had better be taken to email instead of list mail. :-) DaZZa -- SLUG - Sydney Linux Users Group Mailing List - http://www.slug.org.au To unsubscribe send email to [EMAIL PROTECTED] with unsubscribe in the text

I have had 10base2 up to 300 metres in the early days when the sparky who
was brought in to run the cable didn't know what he was doing and thought
"I'd better leave some slack in the roof space, just in case". It might
have worked with power cables, but once the segment started to get loaded
the collisions weren't being propgated fast enough so down the network
went. I put a TDR onto the segment and swore never to employ that sparky
again.
Ouch. That woulda been ugly!
The case where I got up to 227 metres was extremely specialised - two
workstations at one end, two at the other, seperate segment off the server
- grand total of 5 workstations. Oh, and the line drivers on the LAN cards
we used {stuffed if I can remember the brand now} were amazingly above
spec.
Collisions were extremely low, thankfully, or it'da never worked. When the
guy who replaced me tried to stick another 20(!) workstations at the other
end, despite being told not to, it all fell into a screaming heap.

[SLUG] OT: New Toys
Always desiring to keep up to date on the latest "toys" on the markey (and lustfully desiring same !!), I came across this MP3 player that some of you might be interested in; http://www.nomadworld.com/products/nomad-jukebox/ Having spoken to the guys at Creative Labs (Aust), they say no support for Linux is planned because "...all LInux users have Windows anyway, so they can use that..." Talk about alienating your potential customer base !!! Jon P.S.
