remote graphical usage
Hi I am looking of a way to have a local display/keyboard, which is connected on a slow channel ( i.e. modem ) to unix servers. I need a way to run X applictions on the remote server, and see them as they were local. I tried using X - was too slow I tried to use X protocol compression called 'dxpc' - still too slow I tried to use Xvnc - better but still not fast enough. anyone knows of a way to do so except using Citrix or X-win32-server over microsoft's rdesktop ? thanks erez. = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
Re: Bezeq ADSL setup
Shachar, There is no point trying to send a packet larger than your own intrface MTU, with the dont fragment bit set. It shouldn't leave your machine in the first place (because the packet must be fragmented). Dani On Wed, 13 Jun 2001, Shachar Shemesh wrote: Shachar Shemesh wrote: Can someone verify that the setup does, in fact, support the RFC? I.e. - use hping or other packet crafting tool to generate a big (say, 4K) TCP packet with the don't fragment flag set, and see (with tcpdump, or a real sniffer, such as ethereal) whether a fragment needed ICMP is sent. If it is not sent, but the packet does not go through, then there is a real problem. I would try, at this stage, incrementing the TTL, starting from one, and seeing where the ICMP time exceeded messages stop arrive. Wherever that happens - that's the curlpit (or the one before). hping2 can be D/L from http://www.kyuzz.org/antirez/software.html The command line for a single, established, ~ 4KB packet to host foo, with the don't fragment flag set is hping2 foo -c 1 -A -d 4096 --dontfrag hping will display any reply packets received. If you want to test the TTL as well, add --ttl # to the arguments. Shachar Hmm. Now this is interesting. I tried my own advice. I don't have an ADSL modem, but I tried it on our local network. I sent UDP packets, as the company I work for is heavily firewalled, and I wanted to send packets with payload. I tried sending 32K UDP packets (assuming that they must get fragmented on the way). Instead, this is what I got: [root@sshemesh ~]# hping2 www.microsoft.com -2 -c 1 -p 53 -d 32768 --dontfrag --ttl 12 eth0 default routing interface selected (according to /proc) HPING www.microsoft.com (eth0 207.46.230.229): udp mode set, 28 headers + 32768 data bytes TTL 0 during transit from 152.63.21.90 (189.at-1-0-0.TR1.NYC8.ALTER.NET) --- www.microsoft.com hping statistic --- 1 packets tramitted, 0 packets received, 100% packet loss round-trip min/avg/max = 0.0/0.0/0.0 ms Which means that the 32K+change packet got a TTL exceeded, instead of a Fragmentation needed. Strange! So, I ran a sniffer, and tried again. It turns out that the packet got fragmented leaving my own machine. The packet left the network interface, already fragmented. The Don't fragment flag got reset, and the usual more fragments flag was set. The reason I am bringing this up is because it turns out that the MTU on my network interface (Ethernet 10/100, currently in 100) is 100bytes (meaning 1480 bytes + header). Ok, now for a possible answer to the question that has been bothering all of us - why set the MTU on all computers on the network. Could it be that the MTU for ethernet, at least on Linux, is 1500 bytes? Could it be that some computers on the LAN don't autodetect this? Could it be that they then send (or try to) a packet longer than 1500 bytes, which then unceremonially gets dropped by the Linux gateway (incapable of handling the receive)? Could it be that the set MTU on all computers on the network is merely a workaround for this fix?

Re: remote graphical usage
to conclude, as Isee, compressed or not, X sucks on slow lines, so do vnc the only operational solutions are either citrix or ( I'm not so happy to say )Win2K's Rdesktop with both, you can use a 33.6k modem and feel like you are connected directly to the computer regards erez.

Anyway, the fewer less graphics that you have, the better compression can work. Have you tried changing to a theme with no bitmaps and no gradients?

Since then the attendance has gonedown to 25-35, but this is also fine.I think the beginners' series would have worked better if we had asked oneor two people to give all 6 lectures (I apologize to those who told methey were willing to give all the lectures and I pushed them off). 6lectures is plenty of time to show people what a linux system looks like,what you can do with it, how to look after it, and how to install it. Butthe lectures need to be well-coordinated, and the way we divided up thematerial did not work out so well. I think it would also be better to havebeginners' lectures week-after-week, not with large gaps between them. Ifwe try again to run a 6-lecture beginners' course, we will try to correctthese problems. Also I think the right time for a beginners' course is atthe start of the academic year, when it will hopefully appeal to newstudents on campus, who will benefit a lot if they have a unix system ontheir PCs at home. THE ACTIVITY WILL OF COURSE REMAIN OPEN TO ALL!!With the "advanced" lectures, I notice that we get a lot of differentfaces at each of the lectures. I think this is very natural: some peoplecome to all lectures because they want to learn new stuff, but most selectthe subjects they are interested in, and don't have time for the rest. Iam keen that we continue the advanced lectures as a service to the opensource community in the Gush Dan area. The way I suggest to run things issimply that anyone who thinks they have a good lecture to give, or whoknows someone who has a good lecture to give, should contact me with theproposal. I will consult with a few people to check there is interest, andassuming there is, I will arrange a room and a projector at a time that isgood for the lecturer, and put up posters on campus. Thelecturer/organizer can post information to the linux-biu mailing list andon IGLU. I have spent quite a lot of time this semester getting equipmentready for the lectures, and I think from now I will have to insist thatall I can offer is the projector, lecturers will have to bring their own laptops and/or computers. I would like to hear people's feedback on the ideas above. You can writeto me privately at [EMAIL PROTECTED], or post your comments to thelinux-biu list, if you think they are of general interest. Sincerely,Jeremy SchiffPS I will reply separately to the various comments that have been sent tothe list this week.

I need a way to run X applictions on the remote server, and see them as they were local. I tried using X - was too slow I tried to use X protocol compression called 'dxpc' - still too slow I tried to use Xvnc - better but still not fast enough. anyone knows of a way to do so except using Citrix or X-win32-server over microsoft's rdesktop ? How about mlview? I havn't tried it myself, but it seems very promising. (a search on google for mlview finds this as first:) http://www.medialogic.it/projects/mlview/ (Also the 4th in google when searching for 'dxpc citrix'. Of course it helps when you know what to look for - I know this one from an announcement on cola). thanks erez. = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED] didi = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
Re: Bezeq ADSL setup
On Tue, 12 Jun 2001, Dani Arbel wrote: WHY CHANGE DEFAULT MTU ON THE CLIENTS? I do not realy know, but otherwise it won't work Hmmm. Sounds more like a pptp bug than an Orkit bug. The problem occurs only when the LINUX box needs to handle larger packets than 1452 bytes on it's etherside. Warning: (not unlike my previous posts) this is gonna be a bit long: Let's take this setup: Client MTU, linux eth MTU and linux ppp MTU all get set to 1452. Scenario 1: 1. SMTP packet (NO FRAG bit set to 1) leaves client, 2. reaches Linux box, (as a 1452 bit packet because that's how large windows made it), 3. gets stuffed into the 1452 byte ppp interface, 4. gets fed to the pptp program, 5. pptp should now open a tunnel session to the DSL modem, transmit a new packet with ppp capsule inside as a 1500 byte packet (additional acquired headers) over the same 1452-byte-limited ethernet interface, and on these tunnel packets the NO FRAG bit is also set, so it (theoretically) cannot send it (yet, as the hping results showed, it probbably ignores this bit and frags it anyway. bug/feature? ) Now, first let's decide on what's the right thing to do under the circumstances I *think* it's to take the 1452 byte SMTP packet, dump it, and send an ICMP packet to the windows box saying smaller please because 1452 bytes plus the mandatory ppp/tunnel header make up for 1500 bytes which MUST be sent with the DON'T FRAG flag set to the modem, and it can only convey 1452 byte chunks on the ethernet interface. So, given proper operation, the inability to frag further there are only two possibilities: 1. It frags it nontheless, like in the hping example we saw yesterday, and it still works. 2. The pptp program can send an ICMP message back to the windows client saying smaller please. This raises some questions I don't know how to answer: When, on the linux box, the 1452-limited eth interface rejects pptp's 1500 byte capsule packet, an ICMP return message should be sent to the to the IP socket by the routing mechanism, and since ICMP messages are portless, how exactly does the socket know which of it's potentially many TCP or UDP applications should be asked to generate smaller traffic? And how exactly is our application (pptp in this case) notified by the socket that collected the ICMP message that it needs to generate smaller chunks? Scenario 2: SMTP packet (NO FRAG bit set to 0) leaves client, reaches linux box, pptp builds a header over it, comes up with a 1500 byte packet, tries to send over 1452 interface, doens't manage to, and it's in a fix. It can: A. frag the original packet (If it's smart enough; is it?) or: B. the linux routing mechanism can disregard the DON'T FRAG field, frag it nontheless, and it may work, yet we should assume it should not.

I doubt that. The limitation are for a reason. I don't think you understood what I'm suggesting. I'm not suggesting we remove all packet-size limits on the intenet and go off downloading 15MB MP3's in a single chunk. I'm suggesting perhaps this mechanism can be used to overcome the Orkit modem bug broken fragmentation mechanism problem that does not get solved by setting your ppp MTU to 1452 bytes by impopsing a stricter packetsize limitation where it might help solve the problem :-) ---= Miki Shapiro =-- ---= Cell: (+972)-56-322433 = ---= ICQ: 3EE853 =--- ---= Windows Programmer in Rehab =--- - If at first you don't succeed... ..

RE: Bezeq ADSL setup
Just wondering, does anyone know how to return to the root command tree? If you type 'ip' for example, IIRC you will get a prompt something like 10.0.0.138 ip Doing a @atm, for example, will change you to the atm process, but I can't figure out how to get back to root. Closing (@close) the connection and connecting again brings you back to the same place.
