Network (in)Security Interesting hacks and cracks. Info on firewalls, TCP/IP, encryption, networks, and security. The ins and outs of the phone system, caller services, how things work, what's illegal and what's not, cellular phones, beepers, telephony legislation, the PUC, ISDN, taps, who's listening, and switches. Talking about phones, hacking systems, technical advice, and such is completely LEGAL in the United States -- it's covered by the First Amendment. What's illegal is conspiracy to commit a crime. So if you say something like "Meet me at 2am so we can crack a can" or "I changed my cell phone's number myself" you are criminally liable. Stating "You can crack a can by doing thus-and-so" or "If you wanted to change a cell phone's number, you could do it like so" is perfectly OK. Posting passwords, calling card numbers, or credit card numbers is forbidden on this network. Posting such info will get you booted off the net.

Default NFS transfers just hang

On my 2 Linux boxes, Slackware 10 as the NFS server and Fedora Core 3 running as the client NFS transfers just hang.

Any insight into what might be wrong here, this is unnatural by far.

Ive already waited 5 minutes transferring a file to a mounted directory thats less than half a megabyte.

It seems cp'ing to the mounted directory only works on VERY small files like the .bashrc file or another small home directory file.

I'm at a loss here I need help.

Does Slackware 10 support nfs over tcp?

Could it be my rsize and wsize settings?

Server /etc/exports:

code:<pre>

/home/bil 10.0.0.1(rw,async,no_root_squash)

</pre>

Client /etc/fstab:

code:<pre>

10.0.0.2:/home/bil /home/bil nfs noauto,tcp,rw,async,rsize=1024,wsize=1024,nolock 0 0

</pre>

Default Re: NFS transfers just hang

Nevermind I finnally fixed it, it was the NFS client settings, I now used:

code:<pre>

noauto,soft,bg,intr,timeo=2,retrans=2,retry=2,tcp, rsize=32768,wsize=32768

</pre>

and it works fine now.
