How does "Device File: LocLCS1788" become associated with the

A cache in wicd?

TWAIN in Debian 10.
Hi again, I'm interested in moving an image from a JVC Digital Camera KY-F70 to Debian 10. The camera is pre-USB; it has a 50 pin SCSII connector. Probably what the Wikipedia SCSII connector article mentions as HPCN50. The JVC manual mentions TWAIN software for image transfer and claims their software works in Windows 95/98/NT 4.0. Has anyone used TWAIN in Debian? Is there any chance of Debian receiving images using TWAIN directly? Try to make the Windows TWAIN software provided by JVC work under wine? If wine is necessary, can anyone recommend a Windows version from the three noted above? Other ideas? Thanks,...

What you want to do is to apply a > transformation to L7 (application layer), and that's something that > netfilter cannot do. OK, good. In case anyone is interested, this is from https://en.wikipedia.org/wiki/Transport_Layer_Security . "TLS and SSL do not fit neatly into any single layer of the OSI model or the TCP/IP model.[8][9] TLS runs "on top of some reliable transport protocol (e.g., TCP),"[10] which would imply that it is above the transport layer. It serves encryption to higher layers, which is normally the function of the presentation layer. However, applications generally use TLS as if it were a transport layer,[8][9] even though applications using TLS must actively control initiating TLS handshakes and handling of exchanged authentication certificates.[10]" There are two kinds of browser here. (1) Firefox and dillo which handle HTTP and HTTPS properly. (2) The Oberon browser which currently handles only HTTP. So this is the problem which interests me. When firefox or dillo requests any URL, process it as usual. When the Oberon browser requests a HTTP URL, process it as usual. When the Oberon browser requests a HTTPS URL, divert it and apply TLS. Not obvious how these three cases should be separated but this is an idea. For Oberon HTTPS I choose a private port which won't interfere with anything else. 65535 for example. To open a HTTPS page with Oberon, request this URL: HTTP://:65535/. In the host system, where the Oberon browser is running, set up a proxy to intercept traffic to 65535 and apply TLS. Any sense in that? Further tips welcome of course. Thanks,... P. -- https://en.wikibooks.org/wiki/Oberon Tel: +1 604 670 0140Bcc: peter at easthope. ca

Oberon has a client for protocol Telnet and a client for SSH. bash, dash, sudo, rlogin and many other tools don't exist in Oberon. I avoided discussing this deliberately. For most readers it's an annoying digression; for some will cause mental upset. In most Debian situations, once a user is logged in to the system, a shell session is opened without a password.

Re: Authentication for telnet.
From: David Wright Date: Fri, 11 Oct 2019 00:12:45 -0500 > Maybe sometime you'd explain why you prefer telnet to ssh. Several years ago ssh was about 15-20 s connecting whereas telnet required less than a second. Consequently I adopted the habit of using telnet with a password. Recently I wondered about skipping the password and posted the original question about authentication. After the suggestion to use SSH I tried it found it not working. A2 was being overhauled; I won't pursue SSH until that settles. Superimposed on the authentication story was the broken threading causing annoyance to me and too many others. Ideally the syntax required for correct threading would be posted in the debian site. Otherwise one should aim to study the source for MHonArc?

Re: Reply to a message in the Web presentation.
Andrei, Now we can see the result of the test. Messages https://lists.debian.org/debian-user/2020/02/msg00416.html and https://lists.debian.org/debian-user/2020/02/msg00420.html both thread back to your reply which threads back to my original message. They have the same References. 416 was issued with an In-Reply-To field; 420 was issued without In-Reply-To. So, for a 2nd reply at least, the list software maintains the thread without In-Reply-To. Consistent with casual observations a few years back. We might hypothesize a problem in a later generation. Then do further tests or study the source. =8~( At present I'm not so eager.

Trimming boundary of image in GIMP.

Rectangle select can be chosen before any other action. Unfortunately the "rectangle" here is constrained to square. Thanks, ... P. -- Tel: +1 604 670 0140 Bcc: peter at easthope. ca

At least one earlier reply had output in the launching terminal. Here nothing in the terminal. No exit status. Nothing. > More details on exactly what you are doing and how you are getting > your environment set up would be helpful. Obvious factor: replies mention 64 bit machines. 32 b here. Anyone have Zoom running on a 32 b machine with Debian 10? LXDE environment here. Installed strictly according to the instructions at zoom.us. Used apt or apt-get. Checked all the dependancies specified in zoom.us. I found nothing to configure zoom. I guess a working zoom window might have an edit or preferences button. No such thing here.

The automatic startup happens here; about every 30 minutes. The window is always empty. Seems I should carefully work through the installation again. Wondering whether I am the only person try a 32 bit machine. Thanks for all the feedback, ... P. -- Tel: +1 604 670 0140Bcc: peter at easthope. ca

Linphone contacts.
Hi, In Debian 10, linphone contacts are likely stored in ~/.linphone-friends.db. Documentation that I've found doesn't explain. Can some other application extract the contacts as plain text? SQlite? What packages are required? Thanks, ... Peter E. -- https://en.wikibooks.org/wiki/Medical_Machines https://en.wikibooks.org/wiki/Oberon Tel: +1 604 670 0140Bcc: peter at easthope. ca

For others who might be interested, a few observations. https://sqlite.org/cli.html is more complete than the manual. =8~) "man sqlite3" and the Web page list meta-commands, also referred to as dot-commands. Statements are mentioned but not listed. >From the manual, .schema ?PATTERN? Show the CREATE statements matching PATTERN .schema seems to list statements. ".schema main.*" gives some unformatted output. I don't get the question marks. Delimiters? Regular expressionese? Found all I need from linphone contacts. Thanks, ...

Offline systems
Hi, I want to setup a few servers(30+) on intranet network and NONE(not even a master server or anything like that) of them having internet access. What is best approach so I can still install packages on demand ? Try to make custom repo ? But in this case what will be the proper procedure to update the repo ? What is your advice ? Thank you, Peter
