Current setup:
1. 2 RS232 com ports connected with a null modem in between.
2. Open minicom on both
3. Put in 19200,8,N,1 as parameters
4. Open text travels both ways
5. Files sent over Zmodem transfer well.
Both serial adapters are USB, but I tried it also with real com ports, and same story. For simplicity, I will call one adapter "receiving" and the other "sending" to signify from which side I want to send the files through zmodem.
Then I close minicom on the "sending" site without reseting the port (I have also tried setting everything up with stty)
On sending site:
Code:
I tried googling but no solution helps. Please do not try to suggest to use minicom on both sides, because this is going to be an unattended process in the end.

I have a server running Red Hat Enterprise Linux ES (2.6.9.55.ELsmp). When it starts up I get the following error: Uncompressing Linux... Ok, booting the kernel. Red Hat nash version 4.2.1.10 starting WARNING: can't access (null) exec of init ((null)) failed!!!: 14 unmount /initrd/dev failed: 2 Kernel panic - not syncing: Attempted to kill init!
After that I got no response from the OS. I have the installation CD, so I tried to start the rescue mode, while going through the steps I received an error stating that mounting to /mnt/sysimage failed and that if I want to I can access a shell. I really don't know what to do from here
I got a new cable modem so I could get rid of the one I've been leasing from the cable company. It is a Motorola sb6120. Everything is fine with the ISP, it's approved for operation on their network, the only hitch was I had to use my Windows laptop to run their activation software.
At any rate, with the new modem installed, I hop on my Linux box and go to work. I'm seeing some terrible delays in looking up names. When I look with firebug, all the dns lookups for new names are taking 15+ seconds. First I just think maybe the names aren't cached or something is weird for a minute and it will get better, but no. After several restarts and then a couple days persevering with the new cable modem, all DNS queries are still terribly slow (including zypper, mail client, web client).
Suddenly I remember an issue I was having with, I believe version 11.1 when I first installed it. For just the computer on my network with a fixed IP address, DNS resolution was slow like this and if I disabled IPv6 then all was well. I believe there was even a patch issued back then for gethostbyname() that was supposed to fix the issue? So, when I disable IPv6, DNS lookup is back to normal. The two Linux computers on my network had been working fine with IPv6 and the old modem, though, and the Windows box is still working fine even with the new modem.
I can disable IPv6 and make it fast again, but really why should I have to?
Linux box could act as a router? I have one machine running ubuntu, another running windows 7, a cable modem and a switch. Is it posible to share the connection between both computers by making the linux box a "router"?

I am using a cable modem wired to my PC via ethernet. My ISP is Road Runner, through Time Warner Cable.
I entered my IP address, Netmask, and DNS Servers into the network, not using DHCP. This was how I was able to achieve a network connection.
I am connected to the modem, but I cannot get internet.
Here are my stats:
Ubuntu and Xubuntu read my Motorola Surfboard SBV5120 cable modem via USB "out of the box"; Puppy LInux doesn't. The computer I've run them on doesn't support ethernet, so it has to be via USB. what can I do to get Puppy online?
Computer: Systemax
Processor: AMD athlon
Memory: 189 Mb
Hard drive: 40 Gb
I cannot connect my Dell Inspiron 1300 through the NetworkManager "wired" connection, when I try to go direct to the cable modem. It fails to connect.
If I connect the cable modem to my (linksys WRT54GS) wireless router, and then connect my laptop to a wired port in the router, it connects in seconds, successfully.
This has happened to me 2 other times, when I tried to connect my laptop to a client's cable modem, because my client did not have a wireless router available, in their home.
My wireless works fine. This has me perplexed. I'm using Ubuntu 10.04 LTS and NetworkManager Applet 0.8
I've tried some things to see what is going on, such as "ifconfig" "dhclient" as well as modifying the "Auto eth0" parameters and adding my laptop's MAC address, etc. Results were no fix or solution. I feel like I'm headed down the wrong road. Would someone set me straight? I have a feeling this is simpler than I think.
Do I have to actually reset my own or someone's cable modem to get this to work? I don't want to do that unless there's no other way. Is there? Let me know what commands I can or should run.

Running Gentoo with kernel 2.6.29 on a Sparc Ultra 10.

View 1 Replies View RelatedI just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.

View 4 Replies View Relatedhow I could file share, or make the whole Hard Drive (HDD) accessible to another computer. The two other computers I have are a Toshiba Laptop with Ethernet and USB, and a iMac Intel with Firewire, USB, and Ethernet. Putting these to use along with:
Three Ethernet Cables
Two Printer Peripheral USB Cables
The Two Computers
A 2GB Flash Drive
That is all I can think of right now. I do not want to use CDs. In a way, I would like to do a network boot. So, how do I get the whole HDD visible to the others computers (either/both) and be able to write to it? I want to put Xubuntu on it, and earse the rest of the Hard Drive. The computers getting this are the iMac G3s and the eMac G4. The eMac has 256MB RAM, 40GB HDD, and a 700MHz processor. Two iMacs have 128MB RAM, 40GB HDD, and a 600MHz Processor. The other iMac is the same as the rest but has a 500MHz processor.
I ran a program that writes continuously from 1 every line. After some time I ran '/dev/null > temp' Problem1: bash: /dev/null: Permission denied (Yes, the permissions of /dev/null are correct ... crw-rw-rw-. I removed and created it again, but no change) I used 'cat temp' to see the contents and first few lines deleted (working correctly). Problem2: I can't open the file (with double click or with any graphical editor like gedit)
Apart from these problems, I have another question... Is there a way to trim a active log file to say 80% without affecting any logs that server might be writing.
I know GEdit has a bug which prevents it from opening a file with null () characters in it. This is a huge inconvenience for me because I frequently have to open big log files with only a couple rogue 's in them.
Sometimes I just run a quick tr -d '' < file.log > file.log.correct and open the correct file. This is a big nuisance. I would like to have maybe an external tool in GEdit that would execute the above command. I tried writing an external tool action (GEdit plugin) using just:
#!/bin/bash
tr -d ''
Input is "current document", output action is "replace current document". But this isn't working. When I open the file, GEdit shows the familiar red warning; activating the external tool with the warning showing apparently has no effect (I think the script is being called but its input/output are not set).
